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 not forgetfulness but not being aware that we39。 The researchers began with the assumption that one mon feature of Alzheimer39。 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.The memory of the young is better than the old.C.s disease.D.s a rare phenomenon when young people forget something.（2）What statement does the researchers in the new study agree with? A.Illness awareness has nothing to do with Alzheimer39。Recognizing forgetfulness doesn39。s disease.D.s disease.（3）What can be a sign of developing Alzheimer39。Realizing others39。B.Having higher intake of glucose.D.Science fiction.A chemistry book.A science research.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。根據(jù)第一段中的“t remember our neighbor39。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。 （2）考查細節(jié)理解。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。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。 （4）考查推理判斷。故選C。4．犇犇閱讀理解 t just for puters and smartphones, According to a study published last week in the journal Science, scientists have found a way to hack a plant39。 Photosynthesis（光合作用）is the word used to describe how plants use sunlight, water, and carbon dioxide to make their own food. Scientists who conducted the new study say this is a very slow process. Plants use less than 1 percent of the energy available to therm. But by hacking a plant39。 Specifically, scientists hacked the plant39。 Stephen Long is the lead author of the study. He pared a plant39。 The new study sped up the process. By changing the plant39。 genes？ A.B.They will have more beautiful flowers.They will depend less on sunlight.（2）Why does the author mention lightadjusting glasses？ A.To explain the principle of plants39。To help leaves of the plants absorb sunlight.D.improve tobacco plants39。B. leaves and rootsC. living timeincrease the production of corn and rice（4）Which of the following can be the theme of this text？ A.Leaf growing more quicklyC.Photosynthesis and production【答案】 （1）B（2）B（3）D（4）A 【解析】【分析】本文是一篇說明文，科學家通過改變植物的基因，加快光合作用的速度，使植物葉子生長迅速，從而提高植物產(chǎn)量。根據(jù)第一段中的“ scientists have found a way to hack a plant39。故選B。根據(jù)第四段中的“ He pared a plant39。故選B。根據(jù)最后一段中的“ But they think the genetic changes will produce the same results in corn and rice. ”但是他們認為基因的改變將在玉米和水稻中產(chǎn)生相同的結(jié)果。 （4）考查主旨大意，根據(jù)文章內(nèi)容可知，科學家改變植物的基因，加快光合作用的速度，使植物葉子生長迅速，從而提高植物產(chǎn)量。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科研類閱讀，要求考生在捕捉細節(jié)信息的基礎上，進一步根據(jù)上下文的邏輯關(guān)系，進行分析，推理，概括和歸納，從而選出正確答案。 In my memory, winters always used to be really unpleasant.
