Many more are probably harmed invisibly.”一些明顯受到傷害，被塑料制成的廢棄物品卡住了。可能有更多的人受到無形的傷害。可知選B。 （3）考查推理判斷。根據(jù)最后一段中的“It39。s a matter of building the necessary institutions and systems, he says, ideally before the ocean turns into a thin soup of plastic.”他說最好在海洋變成塑料湯之前建立一個必要的機構(gòu)和制度的問題，可推知選C。 （4）考查推理判斷?？v觀全文可知，本題介紹了塑料垃圾給海洋以及海洋生物帶來的危害。是一篇環(huán)境保護類閱讀，因此選C。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇環(huán)保類閱讀，考生需要準確捕捉細節(jié)信息，同時根據(jù)上下文進行邏輯推理，從而選出正確答案。4．犇犇閱讀理解 In our twenties, we find it funny when we can39。t remember our neighbor39。s cat39。s name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it brain freeze. In our forties, we laugh it off as a senior moment and follow up with one of these old age jokes. But the reality is that there es a point when being forgetful stops being funny and starts to seem a bit dreadful. You think, Am I losing it？Or worse, Is this a sign of Alzheimer39。s disease（老年癡呆癥）？ Well, don39。t worry. The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer39。s disease（AD）. The researchers in a new study show that it39。s not forgetfulness but not being aware that we39。re forgetful that we should fear. The researchers began with the assumption that one mon feature of Alzheimer39。s disease is a damaged awareness of illness. And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with mild cognitive（認知的）damage will progress to fullon AD. For the study, mild cognitive damage was defined as someone whose mental state was considered healthy but who had either plained of memory loss or had suffered objective memory loss. The researchers used existing data for 1, 062 people between the ages of 55 and 90 that had been recorded over a 12year period. The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an objective marker of the sort of reduced brain function that goes along with expected, glucose uptake was reduced in those with AD. What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness. Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.（1）What can be implied from paragraph 1？ A.People can be forgetful at different ages.B.The memory of the young is better than the old.C.Old people are most afraid of getting Alzheimer39。s disease.D.It39。s a rare phenomenon when young people forget something.（2）What statement does the researchers in the new study agree with? A.Being aware all the time is a fearful thing.B.Illness awareness has nothing to do with Alzheimer39。s disease.C.Recognizing forgetfulness doesn39。t mean developing Alzheimer39。s disease.D.Realizing forgetfulness must be a sign of developing Alzheimer39。s disease.（3）What can be a sign of developing Alzheimer39。s disease? A.Realizing others39。 forgetfulness.B.Reduced uptake of glucose.C.Having higher intake of glucose.D.Expected increase in brain function.（4）From which is the text probably taken? A.Science fiction.B.A chemistry book.C.A science research.D.A health brochure.【答案】 （1）A（2）C（3）B（4）C 【解析】【分析】本文是一篇說明文，介紹了如何預(yù)測你的記憶喪失是否是老年癡呆癥,一項新的研究表明，不是遺忘，而是沒有意識到我們的健忘讓人們感到害怕。 （1）考查推理判斷。根據(jù)第一段中的“In our twenties, we find it funny when we can39。t remember our neighbor39。s cat39。s name or a handsome actor who starred in a famous movie. In our thirties, we jokingly call it ‘brain freeze’ In our forties, we laugh it off as a‘senior moment’ and follow up with one of these old age jokes. But the reality is that there es a point when being forgetful stops being funny and starts to seem a bit dreadful. ”在二十多歲的時候，當我們記不起鄰居的貓的名字或是主演一部著名電影的英俊演員時，我們覺得很有趣。在三十多歲的時候，我們開玩笑地稱它為“大腦凍結(jié)”，在四十多歲的時候，我們把它當作“老年時期”來嘲笑，然后繼續(xù)講這些老年笑話。但現(xiàn)實是，有這樣的時候，健忘不再有趣，而且看起來有點可怕，可推知選A。 （2）考查細節(jié)理解。根據(jù)第二段中的“ The fact that you recognize your own forgetfulness may be a very good sign, at least in terms of the possibility of your developing Alzheimer39。s disease（AD） ”承認自己的健忘也許是一個很好的跡象，至少從你患老年癡呆癥,的可能性來看，可知選C。 （3）考查細節(jié)理解。根據(jù)第四段中的“ It is an objective marker of the sort of reduced brain function that goes along with expected, glucose uptake was reduced in those with AD. ”這是一個患有老年癡呆癥降低了腦功能的客觀標志。正如所料，老年癡呆癥患者的葡萄糖吸收降低，故選B。 （4）考查推理判斷。縱觀全文可知，是一項科學研究，介紹了如何預(yù)測你的記憶喪失是否是老年癡呆癥,故選C。 【點評】本題考點涉及細節(jié)理解和推理判斷兩個題型的考查，是一篇科研類閱讀，考生需要準確掌握細節(jié)信息，并根據(jù)上下文進行邏輯推理，從而選出正確答案。5．犇犇Choose the one that fits best according to the information given in the passage you have just read.
