2022年考博英語-湖南農(nóng)業(yè)大學(xué)考前模擬強(qiáng)化練習(xí)題（附答案詳解） 1. 單選題 Smoking is so harmful to personal health that it kills ________ people each year than automobile accident. 問題1選項(xiàng) A.seven more times B.seven times more C.over seven times D.seven times 【答案】B 【解析】考查倍數(shù)的用法。根據(jù)關(guān)鍵詞than，我們可以知道答案選“A+倍數(shù)+形容詞或副詞的比較級(jí)+than+B”的變形。more和over一般是放在倍數(shù)后面，所以A，C選項(xiàng)排除。D選項(xiàng)不符合語法。 2. 單選題 The meeting’s been cancelled. Ann（  ） all that work. 問題1選項(xiàng) A.need to do B.need have C.needn’t have done D.needed not to do 【答案】C 【解析】考查need的用法。句意：會(huì)議被取消了。安娜（）所有工作。前面分句中的時(shí)態(tài)是過去完成時(shí)，所以這里的主句也是用過去時(shí)態(tài)。need作為情態(tài)動(dòng)詞時(shí)，表示“需要”或“必須”，沒有性和數(shù)的變化，通常用于否定句和疑問句，A、B、C選項(xiàng)都不符合題意，所以答案選C選項(xiàng)，needn’t have done 是做了不需要做的事情。翻譯：會(huì)議已經(jīng)被取消了，Ann做了不需要做的工作。 3. 單選題 The Indians see little（  ）for success and become frustrated, because they usually go to inferior school and often cannot adjust to life in the city. 問題1選項(xiàng) A.instinct B.proposition C.priority D.prospect 【答案】D 【解析】考查名詞辨析。A選項(xiàng)“直覺”；B選項(xiàng)“命題，主題”；C選項(xiàng)“優(yōu)先權(quán)”；D選項(xiàng)“前途，預(yù)期”。句意：印第安人似乎只有一點(diǎn)點(diǎn)對(duì)成功（）而且變得沮喪，因?yàn)樗麄兺ǔＨソ虒W(xué)質(zhì)量不好的學(xué)校而且不能適應(yīng)城市生活。從關(guān)鍵詞go to inferior school and often cannot adjust to life in the city可知，印第安人成功希望不是很大，所以答案選D。 4. 單選題 Apple Computer has unveiled its new desktop computer design, ________ all disk drives and processors into a flat display less than two inches thick. 問題1選項(xiàng) A.enclosing B.which contains C.including D.which integrates 【答案】D 【解析】考查非限制性定語從句。A選項(xiàng)“圍住，附上”；B選項(xiàng)“這些包括”；C選項(xiàng)“包括”；D選項(xiàng)“這些把……合并在了一起”。句意：蘋果公司公開了新款筆記本電腦的設(shè)計(jì)，（）所有硬盤驅(qū)動(dòng)器和處理器到一個(gè)少于兩英寸厚的平板顯示器中?？崭窈竺嬗袀€(gè)關(guān)鍵介詞into，能夠和into搭配的只有integrates，所以答案選D。 5. 單選題  I can speak French a little but（  ）you. 問題1選項(xiàng) A.not as good as B.not so well than C.not so better as D.not so well as 【答案】D 【解析】詞組辨析。句意：我會(huì)講一點(diǎn)點(diǎn)法語但是（）你。這里屬于同級(jí)比較，所以排除B，C。這里的謂語動(dòng)詞是speak，所以要用副詞well修飾，答案選D。在否定句里，good的同級(jí)比較是so good as，所以A不能選。 6. 翻譯題 靜下來想想，我這樣一個(gè)出身貧寒、經(jīng)歷坎坷的人，居然能活到92歲，實(shí)在有點(diǎn)奇怪。過了80歲，經(jīng)常有人問我，有什么養(yǎng)生之道。我不僅不懂得養(yǎng)生，而且還有一些不好的習(xí)慣。 我性急圖快，走路快，下筆快，吃飯更快，簡(jiǎn)直是狼吞虎咽，因此，得了胃病。醫(yī)生治好了我的病，但沒有治好我的習(xí)慣。 【答案】When I think about it, it’s a little strange that someone who came from such a poor background and has been through so many hardships should have lived to be 92. When I was 80 years old, I was often asked for advice on how to keep fit. I not only don’t know how to keep in good health, but also have some bad habits. I was quick to walk, quick to write, even faster to eat, just wolfed down, so I got stomach trouble. The doctor cured me of the disease, but not of my habit. 7. 不定項(xiàng)選擇題 The energy contained in rock within the earth’s crust represents a nearly unlimited energy source, but until recently commercial retrieval has been limited to underground hot water and/or steam recovery systems. These systems have been developed in areas of recent volcanic activity, where high rates of heat flow cause visible eruption of water in the form of geysers and hot springs. In other areas, however, hot rock also exists near the surface but there is insufficient water present to produce eruptive phenomena. Thus a potential hot dry rock (HDR) reservoir exists whenever the amount of spontaneously produced geothermal fluid has been judged inadequate for existing commercial systems. As a result of recent energy crisis, new concepts for creating HDR recovery systems—which involve drilling holes and connecting them to artificial reservoirs placed deep within the crust—are being developed. In all attempts to retrieve energy from HDR’s artificial stimulation will be required to create either sufficient permeability or bounded flow paths to facilitate the removal of heat by circulation of a fluid over the surface of the rock. The HDR resource base is generally defined to included crustal rock that is hotter than 150°C, is at depths less than ten kilometers and can be drilled with presently available equipment. Although wells deeper than ten kilometers are technically feasible, prevailing economic factors will obviously determine the commercial feasibility of wells at such depths. Rock temperatures as low as 100°C may be useful for space heating (heating of spaces especially for human comfort by any means (as fuel, electricity, or solar radiation) with the heater either within the space or external to it); however, for producing electricity, temperatures greater than 200 °C are desirable. The geothermal gradient, which specifically determines the depth of drilling required to reach a desired temperature, is a major factor in the recoverability of geothermal resources. Temperature gradient maps generated from oil and gas well temperature-depth records kept by the American Association of Petroleum Geologists suggest that trappable high-temperature gradients are distributed all across the United States. (There are many areas, however, for which no temperature gradient records exist.) Indications are that the HDR resource base is very large. If an average geothermal temperature gradient of 22°C per kilometer of depth is used, a staggering 13, 000, 000 quadrillion B.T.U.s of total energy are calculated to be contained in crustal rock to a ten-kilometer depth in the United States. If we conservatively estimate that only about 0.2 percent is recoverable, we find a total of all the coal remaining in the United States. The remaining problem is to balance the economics of deeper, hotter, more costly wells and shallower, cooler, less expensive wells against the value of the final product, electricity and/or heat. 1. The primary purpose of the passage is to ________. 2. The passage would be most likely to appear in a ________. 3. According the passage, an average geothermal gradient of 22°C per kilometer of depth can be used to ________. 4. It can be inferred from the passage that the availability of temperature-depth records for any specific area in the United States depends primarily on the ________. 問題1選項(xiàng) A.warn the users of coal and oil that HDR’s are not an economically feasible alternative B.alert readers to the existence of HDR’s as an available energy source C.encourage the use of new techniques for the recovery of energy from underground hot water and steam D.document the challenges that have been surmounted in the effort to recover energy from HDR 問題2選項(xiàng) A.technical journal article concerned with the recoverability of newly identified energy sources B.petrological research report focused on the history of temperature-depth records in the United States C.consumer report describing the extent and accessibility of remaining coal resources D.congressional report urging the conservation of oil and natural gas reserves in the United States 問題3選項(xiàng) A.provide comparisons between hot water and HDR energy sources in the United States B.balance the economics of HDR energy retrieval against that of underground hot water or steam recovery systems. C.revise the estimates on the extent of remaining coal resources in the United States D.estimate the total HDR resource base in the United States 問題4選項(xiàng) A.history of successful hot water or steam recovery efforts in that area B.possibility that HDR’s may be found in that area C.failure of inhabitants to conserve oil or gas reserves in that area D.existence of previous attempts to obtain oil or gas in that area 【答案】第1題:B 第2題:A 第3題:D 第4題:D 【解析】第1題:主旨大意題。A選項(xiàng)“提醒那些使用煤炭或者石油的人熱干石不是很經(jīng)濟(jì)的替代品”；B選項(xiàng)“提醒讀者熱干石是一個(gè)可用的能源”；C選項(xiàng)“鼓勵(lì)使用新技術(shù)，從地下熱水和蒸汽中回收能量”；D選項(xiàng)“記錄在從HDR中回收能源的努力中已經(jīng)克服的挑戰(zhàn)”。根據(jù)題干定位到第一段第一句The energy contained in rock within the earth’s crust represents a nearly unlimited energy source, but until recently commercial retrieval has been limited to underground hot water and/or steam recovery systems.（地殼中巖石所含的能量是一種幾乎無限的能源，但直到最近，商業(yè)回收還僅限于地下熱水和/或蒸汽回收系統(tǒng)。）從這里可以看出HDR是可用資源，雖然還沒有被開發(fā)完全但是潛力巨大，因此答案選B。A、C、D選項(xiàng)文中沒有提及。 第2題:推理判斷題。題干：這篇文章最可能出現(xiàn)在哪里。A選項(xiàng)“有關(guān)新發(fā)現(xiàn)的能源的可恢復(fù)性的技術(shù)期刊文章”；B選項(xiàng)“集中關(guān)注美國(guó)的溫度——深度記錄的歷史巖石學(xué)研究報(bào)告”；C選項(xiàng)“描述剩余煤炭資源的范圍和可及性的消費(fèi)者報(bào)告”；D選項(xiàng)“一份敦促美國(guó)保護(hù)石油和天然氣儲(chǔ)備的國(guó)會(huì)報(bào)告”。文章都是邏輯嚴(yán)謹(jǐn)，用詞科學(xué)，所以最可能出現(xiàn)在期刊里。文章的中心內(nèi)容是HDR這種資源只是稍微提及了美國(guó)，所以不選B選項(xiàng)。 第3題:事實(shí)細(xì)節(jié)題。題干：每千米深度的平均地溫梯度為22℃就可以用來干什么？A選項(xiàng)“用來比較美國(guó)的熱水和HDR能源”；B選項(xiàng)“平衡HDR能量回收與地下熱水或蒸汽回收系統(tǒng)的經(jīng)濟(jì)效益?！保籆選項(xiàng)“對(duì)美國(guó)剩余煤炭資源的估計(jì)”；D選項(xiàng)“估計(jì)美國(guó)HDR資源總量”。根據(jù)題干我們定位到最后一段第二句話If an average geothermal temperature gradient of 22°C per kilometer of depth is used, a staggering 13, 000, 000 quadrillion B.T.U.s of total energy are calculated to be contained in crustal rock to a ten-kilometer depth in the United States.（如果使用每千米深度22℃的平均地?zé)釡囟忍荻?，?jì)算出美國(guó)10千米深度的地殼巖石中包含的總能量高達(dá)13000000萬億B.T.U）然后再根據(jù)第三段第一句話The HDR resource base is generally defined to included crustal rock that is hotter than 150°C, is at depths less than ten kilometers and can be drilled with presently available equipment.（HDR資源基礎(chǔ)的定義通常包括溫度高于150°C、深度小于10公里、可以用現(xiàn)有設(shè)備鉆取的地殼巖石。）因此答案選D。 第4題:事實(shí)細(xì)節(jié)題。題干：從文章中可以推斷出，美國(guó)任何一個(gè)特定地區(qū)的溫度——深度記錄的可用性主要取決于什么。A選項(xiàng)“該地區(qū)熱水或蒸汽采收率的成功歷史”；B選項(xiàng)“HDR在那個(gè)區(qū)域被發(fā)現(xiàn)的可能性”；C選項(xiàng)“居民沒有成功保存那個(gè)地區(qū)的石油或天然氣儲(chǔ)備”；D選項(xiàng)“以前在該地區(qū)曾試圖獲得石油或天然氣”。Temperature gradient maps generated from oil and gas well temperature-depth records kept by the American Association of Petroleum Geologists suggest that trappable high-temperature gradients are distributed all across the United States（根據(jù)美國(guó)石油地質(zhì)學(xué)家協(xié)會(huì)保存的油氣井溫度——深度記錄生成的溫度梯度圖顯示，可圈閉的高溫梯度分布在美國(guó)各地）從這里可知答案選D。       8. 單選題 It was no ________ that his car was seen near the bank at the time of the robbery. 問題1選項(xiàng) A.coincidence B.convention C.certainty D.complication 【答案】A 【解析】考查名詞辨析。A選項(xiàng)“巧合，一致發(fā)生”； B選項(xiàng)“大會(huì)，公約”；C選項(xiàng)“確認(rèn)”；D選項(xiàng)“并發(fā)癥，復(fù)雜”。句意：在銀行被搶的時(shí)候他的車被看到停在附近，這絕對(duì)不是（）。根據(jù)句意，這個(gè)人在推測(cè)為什么正好在銀行被搶的時(shí)候在附近看到了他的車，會(huì)不會(huì)也太巧了。這里結(jié)合選項(xiàng)應(yīng)該選A。 9. 單選題 For decades the food industry has been known for mainly providing sugary or fat-laden products, ________ with ceaseless advertising. 問題1選項(xiàng) A.developed B.lifted C.raised D.promoted 【答案】D 【解析】考查動(dòng)詞辨析。A選項(xiàng)“發(fā)展”；B選項(xiàng)“提高”；C選項(xiàng)“增長(zhǎng)，培養(yǎng)”；D選項(xiàng)“推廣，推銷”。句意：數(shù)十年來食品產(chǎn)業(yè)以主要為提供高糖高脂肪的產(chǎn)品聞名，（）無休止的廣告。廣告一般是用來推廣食品，以達(dá)到讓食品賣的更好的效果，所以答案選D。 10. 單選題 The hospital is now discounting 10 standard operations, ________ having a baby to undergoing a heart bypass. 問題1選項(xiàng) A.ranging from B.covering C.consisting of D.comprising 【答案】A 【解析】考查詞義辨析。A選項(xiàng)“從……到……”；B選項(xiàng)“覆蓋，包含”；C選項(xiàng)“包括，組成”；D選項(xiàng)“包括”。句意：這家醫(yī)院現(xiàn)在不考慮（做）10種標(biāo)準(zhǔn)手術(shù)，（）接生到心臟搭橋手術(shù)。從句子關(guān)鍵詞“to”，選項(xiàng)中和to搭配的只有range from...to；所以答案選A。consist of和comprise后面列舉的例子一般用and連接。 11. 單選題 It is time we（  ） in bed. 問題1選項(xiàng) A.should be B.were C.will be D.are 【答案】A 【解析】考查虛擬語氣。it is time后面接虛擬語氣，有兩種表達(dá)方式，一種是should+動(dòng)詞原形，另一種是用過去式表將來時(shí)，所以答案A，B都可。 12. 單選題 Not only（  ）me too much, but didn’t do a good repair job. 問題1選項(xiàng) A.did he charge B.he charged C.he has charged D.has he charged 【答案】A 【解析】考查部分倒裝。句意：他不僅收費(fèi)高，而且修理工作也沒有做得很好。Not等具有否定意義的詞放于句首時(shí)，句子用部分倒裝，所以排除B、D選項(xiàng)。but also后面那句話的時(shí)態(tài)是一般過去時(shí)，所以前面的句子也是用一般過去時(shí)，因此排除D選項(xiàng)，答案選A。 13. 單選題 I

be able to ________ between right and wrong. 問題1選項(xiàng) A.discard B.discern C.disperse D.disregard 【答案】B 【解析】考查動(dòng)詞辨析。A選項(xiàng)“拋棄”；B選項(xiàng)“辨別，察覺”；C選項(xiàng)“分散”；D選項(xiàng)“不理睬”。句意：他太年輕了不能（）對(duì)與錯(cuò)。對(duì)錯(cuò)之間是需要判斷的，所以答案選B。 15. 翻譯題 愛因斯坦（Einstein）曾把一位著名科學(xué)家的創(chuàng)造力歸因?yàn)椤八麤]上過學(xué)，因此保留了能自由思考的能力。”看起來愛因斯坦好像是在批評(píng)學(xué)校教育。實(shí)際上學(xué)校的功能是傳授知識(shí)和文明，而不只是培養(yǎng)天才。如果學(xué)校只傳授知識(shí)，就會(huì)破壞創(chuàng)造力和天才。但是，如果一個(gè)社會(huì)里都是天才，它就會(huì)解體。所以，學(xué)校教育要培養(yǎng)社會(huì)所需的各個(gè)層次的人才。 【答案】Einstein once ascribed the creativity of a famous scientist to that “he has never went to the school, so he could retain the ability of thought.” It seems that he was criticizing the school education. In fact, the function of school is not cultivating geniuses but imparting knowledge and advancing civilization. If school is just a place to impart knowledge, people’s creativity and talent will be ruined. However, a society in which people are all talent would be broken down. So, school education should raise all-level geniuses that the society needs. 16. 不定項(xiàng)選擇題 The idea has reigned for years that the aging brain’s neurons die off by as many as 100,000 a day—taking with them life’s cherished memories. But, in fact neuron-biologists such as Alan Peters of Boston University have shown in recent studies that, while brain cells may shrink in old age, they don’t die off in large numbers. What’s more, say neuroscientists, it’s primarily the brain’s “hardware”—the billions of telephone-line-like connections and relay switches which act as processing equipment—that is vulnerable to wearing out with age. The brain’s “software”—the actual information that fills up the mind over a lifetime—doesn’t necessarily deteriorate. If anything, it can grow more sophisticated. So, just as running the latest software program on an old computer will take more time and may involve some trouble, one car still possess a first-rate intelligence while losing some cognitive speed later in life. When mental abilities do pass their peak, memory isn’t the first to go, Powell and others say. It’s usually the brain’s capacity to make sense of spatial relationships—map-reading or finding your car at the mall—which may begin to get difficult in your 40s. A decade later, the abstract reasoning required to make analogies dips downward. Next to drop is “verbal memory after delay”—remembering details of a story after having turned attention to other tasks. But some mental skills, such as the ability to concentrate or calculate math, seem to remain sturdy long into old age. And “procedural” memory—how to play golf or ride a bike—is usually not touched by aging. Even “common” memory loss, however, shouldn’t be considered normal. It could be treatable. Neurologists at Harvard are finding that, later in life, the brain often produces less acetylcholine (乙酰膽堿), a neurotransmitter involved in memory. Tentative results suggest that drugs could mimic the missing chemical. At least a dozen other substances are also being studied as potential memory boosters. 1. According to the passage, when we are old ________. 2. According to the neuroscientists, the information in our mind ________. 3. The neuroscientists compare our brain with computer to show that ________. 4. According to the passage, at what age do our brains work best? 5. What might happen when we are in our 50s? 6. Which of the following is the best title of this passage? 問題1選項(xiàng) A.our brain neurons die off very quickly B.our brain neurons do not die at all C.our brain neurons may become smaller D.our brain neurons take away our cherished memories 問題2選項(xiàng) A.is easy to be lost at old ages B.does not change at old ages C.wears out easily with age D.can be more complicated at old ages 問題3選項(xiàng) A.when people get old, their brains work slowly as old machines B.human beings are as intelligent as computers C.the structure of our brains is very complicated D.a great deal of information can be stored in our brains 問題4選項(xiàng) A.When we are younger than thirty. B.When we are about forty. C.When we are over fifty. D.When we are very old. 問題5選項(xiàng) A.We begin to forget where we have put our things. B.We begin to have difficulty in explaining why two things are alike. C.We begin to forget the message that we have been told. D.We begin to forget how to operate a machine. 問題6選項(xiàng) A.How To Keep Our Memories At Old Ages B.Memories Goes First When We Are Old C.Exploring The Myth Of Our Memory D.How To Stay Mentally Alert 【答案】第1題:C 第2題:D 第3題:A 第4題:B 第5題:B 第6題:C 【解析】第1題:事實(shí)細(xì)節(jié)題。根據(jù)題干定位到第一段最后一句...while brain cells may shrink in old age, they don’t die off in large numbers.（……雖然我們的腦細(xì)胞會(huì)在晚年萎縮，但是并不會(huì)出現(xiàn)大量死亡的現(xiàn)象）從這句可知腦細(xì)胞不會(huì)很快速地死亡，也不是不會(huì)死亡只是小范圍地死亡，所以A選項(xiàng)“我們的腦細(xì)胞會(huì)很快的死亡”和B選項(xiàng)“我們的腦細(xì)胞完全不會(huì)死亡”錯(cuò)誤；D選項(xiàng)“我們的腦細(xì)胞帶走珍貴的會(huì)議”不符合邏輯，因?yàn)槭悄X細(xì)胞的死亡才會(huì)造成記憶缺失并不是腦細(xì)胞帶走我們的記憶。萎縮的細(xì)胞會(huì)要比普通細(xì)胞小。所以答案是C選項(xiàng)“我們的腦細(xì)胞可能會(huì)變小”。 第2題:事實(shí)細(xì)節(jié)題。從題干定位到第二段倒數(shù)第二三句話The brain’s “software”—the actual information that fills up the mind over a lifetime—doesn’t necessarily deteriorate. If anything, it can grow more sophisticated.（大腦的“軟件”——一生中裝滿了大腦的實(shí)際信息——并不一定會(huì)退化。如果要說有什么的話，那就是它（腦細(xì)胞）變得更加復(fù)雜了）從這句話可知儲(chǔ)存著大腦信息的“軟件”不會(huì)退化，所以“軟件”里面的信息也不會(huì)輕易丟失，A選項(xiàng)“我們腦海的信息在老年的時(shí)候容易忘記”；B選項(xiàng)“我們腦海的信息在老年的時(shí)候也不會(huì)改變” C選項(xiàng)“我們腦海的信息在老年的時(shí)候容易磨損”錯(cuò)誤；D選項(xiàng)“我們腦海的信息在老年的時(shí)候會(huì)變得復(fù)雜”正確。  第3題:事實(shí)細(xì)節(jié)題。根據(jù)題干定位到第二段前面三句話it’s primarily the brain’s “hardware”—the billions of telephone-line-like connections and relay switches which act as processing equipment—that is vulnerable to wearing out with age. The brain’s “software”—the actual information that fills up the mind over a lifetime—doesn’t necessarily deteriorate. If anything, it can grow more sophisticated.（主要是大腦的“硬件”——數(shù)十億充當(dāng)處理設(shè)備的像電話線一樣的連接和繼電器開關(guān)（的細(xì)胞）——很容易隨著年齡的增長(zhǎng)而磨損。大腦的“軟件”——在一生中裝滿了大腦的實(shí)際信息——并不一定會(huì)退化。如果要說有什么的話，那就是它（腦細(xì)胞）變得更加復(fù)雜了。）隨著年齡的增長(zhǎng)腦細(xì)胞里儲(chǔ)藏的信息變得復(fù)雜了，但是處理信息的細(xì)胞卻隨著年齡的增長(zhǎng)老化，這一現(xiàn)象就很像一臺(tái)舊電腦運(yùn)行著最新的軟件，所以A選項(xiàng)“當(dāng)人們變老之后，我們大腦的工作會(huì)如同一臺(tái)舊電腦般運(yùn)行得緩慢”正確。B選項(xiàng)“人類像電腦一樣聰明”，這個(gè)說法不符合我們生活邏輯；C選項(xiàng)“我們大腦結(jié)構(gòu)非常復(fù)雜”和D選項(xiàng)“大量信息可以儲(chǔ)存在我們腦海中”文章沒有提及。 第4題:事實(shí)細(xì)節(jié)題。根據(jù)題干定位到第三段 When mental abilities do pass their peak, memory isn’t the first to go, Powell and others say. It’s usually the brain’s capacity to make sense of spatial relationships—map-reading or finding your car at the mall—which may begin to get difficult in your 40s.（鮑威爾和其他生物學(xué)家說，當(dāng)腦力達(dá)到頂峰時(shí)，記憶力并不是最先消失的。（最先消失的）通常是大腦理解空間關(guān)系的能力——看地圖或在商場(chǎng)里找到你的車——在你40多歲的時(shí)候，這可能開始變得困難。）從begin to（開始）這個(gè)關(guān)鍵詞可知40歲的時(shí)候，我們的大腦開始走下坡路了，所以40歲時(shí)，我們大腦就處于巔峰狀態(tài)，因而答案選B。 第5題:事實(shí)細(xì)節(jié)題。根據(jù)題干定位到第四段第二句話A decade later, the abstract reasoning required to make analogies dips downward.（十年后，進(jìn)行類比所需要的抽象推理能力下降了。）分析兩件事的異同需要我們的抽象邏輯能力，所以B選項(xiàng)“我們解釋某兩件事的相似之處開始變得困難”正確，定位到最后一段第一句話Even “common” memory loss, however, shouldn’t be considered normal. It could be treatable.（然而，即使是“普通的”失憶也不應(yīng)該被視為正常。它是可以治療的。）失憶不是正常現(xiàn)象而且是可以治愈的，而A選項(xiàng)“我們開始忘記把東西放哪了”，C選項(xiàng)“我們開始忘記別人告訴我們的信息”，D選項(xiàng)“我們開始忘記怎么操作機(jī)械了”，這些都是關(guān)于失憶的現(xiàn)象的，所以A，C，D不選。 第6題:主旨大意題。文章全文都是在客觀地描述我們腦細(xì)胞隨著年齡的增長(zhǎng)會(huì)出現(xiàn)什么情況，沒有告訴我們應(yīng)該去什么措施，所以A選項(xiàng)“怎么在老年的時(shí)候保持記憶”，以及D選項(xiàng)“怎樣保持機(jī)警”不選。B選項(xiàng)“當(dāng)我們老了，記憶排在第一位”雖然文中有提及，但是不是主題，而且這句話和文章內(nèi)容相對(duì)的，所以排除。文章內(nèi)容是根據(jù)記憶來展開的，第一段以人們的錯(cuò)覺開頭，然后介紹了生物學(xué)家相關(guān)的實(shí)驗(yàn)驗(yàn)證腦細(xì)胞和記憶的關(guān)系，然后描述隨著年齡的增長(zhǎng)，記憶出現(xiàn)什么樣的情況，所以答案選C選項(xiàng)“探尋我們記憶之謎”。           17. 單選題 He noticed the helicopter hovering over the field. Then to his astonishment, he saw a rope ladder _________out and three men climbing down it. 問題1選項(xiàng) A.throwing B.being thrown C.having thrown D.having been thrown 【答案】B 【解析】考查時(shí)態(tài)。句意：他意識(shí)到直升機(jī)盤旋在上空。在他意料之外的是，他看到繩梯扔出來然后三個(gè)男人拾級(jí)而下。繩子是被扔出所以要用被動(dòng)語態(tài)，A、C選項(xiàng)排除；and連接的是兩個(gè)并列的賓語，而and后面的男人用的現(xiàn)在分詞，沒有使用現(xiàn)在分詞的完成式，所以and前面也應(yīng)該保持一致，所以答案選B。 18. 翻譯題 本把小鳥拿到廚房，輕輕地放在地板上，它沒有動(dòng)。本摘下蒙了水汽的眼鏡，把臉擦干。小鳥看著他，本輕輕地?fù)犴標(biāo)挠鹈? 他仔細(xì)地查看受了傷的翅膀?？磥頉]有希望了，翅膀幾乎被打掉，子彈打碎了骨頭。本知道小鳥正在死去，但是他無能為力。他在想小鳥是不是很疼，一只小鳥能夠活多久？他想，那個(gè)捕殺者是對(duì)的，小鳥就快死了，活不了了。 【答案】Ben took the bird to the kitchen and laid it gently on the floor. It didn’t move. Ben took off his damp glasses and dried his face. The bird looked at him, and Ben gently smoothed its feathers. He examined the injured wing carefully. There seemed to be no hope. The wing was almost blown off, the bullet shattered the bone. Ben knew the bird was dying, but there was nothing he could do. He wondered if the bird was in pain. How long would a bird live? The hunter was right, he thought. The bird was going to die. 19. 單選題 The idea of traveling through（  ）space to other planets interests many people today. 問題1選項(xiàng) A.a B.the C./ D.one 【答案】C 【解析】考查冠詞。句意：漫游太空去另一個(gè)星球這個(gè)想法現(xiàn)在引起了很多人的興趣。 sun、star一樣是物質(zhì)名詞，是獨(dú)一無二的事物，所以前面應(yīng)該加定冠詞the，因此答案選C。特指世界上獨(dú)一無二的事物或自然現(xiàn)象。但space表示“太空”，nature表示“大自然”時(shí)，均不能與冠詞連用。 20. 單選題 The solution works only for couples who are self-employed, don’t have small children and get along ________ to spend most of their time together. 問題1選項(xiàng) A.so well B.too well C.well as D.well enough 【答案】A 【解析】考查固定搭配。句意：這個(gè)解決方案只對(duì)那些自由工作者，沒有小孩且在一起的時(shí)候大部分時(shí)間都相處得（）的夫妻來說有用。結(jié)合選項(xiàng)這里詞意要填“很好”，所以不能選B選項(xiàng)，因?yàn)閠oo…to是“太……而不能”；C，D選項(xiàng)則會(huì)把因果倒置“因?yàn)橄嗵幍煤盟源蟛糠謺r(shí)間待在一起”。so…to“太……而”這個(gè)搭配與too…to的意思相對(duì)，答案選A。
