The study was done with a variety of animals using phenomenon based on the maximum speed of flashes of light an individual can see before the light source is seen as constant. Dogs, for example, have eyes with a refresh rate higher than humans. 故選D。根據(jù)最后一段中的“Leaning to be wise is basically learning what is not possible；and what is possible but so difficult that it is not worth all the trouble one has to go through to get there. Mostly, it is learning about human nature；how real people behave and react, as against how one would like them to behave and react. One can read and hear lot of idealistic stuff about how to make the world a better place, which would be found if it was based on an accurate observation of human nature,”成為智者，要大體上知道什么是不可能的。最重要的是了解人性，了解真實的人是如何行為和反應(yīng)的，以及人們希望他們?nèi)绾涡袨楹头磻?yīng)的。故選A。根據(jù)對愛因斯坦所的發(fā)現(xiàn)可知，他的偉大的發(fā)現(xiàn)是在2025歲之間，更是印證了人類大腦在20年代初達(dá)到了巔峰，可推斷出，本段主要研究人類大腦巔峰期，故選B。根據(jù)第一段“It has been discovered that after the age of sixteen, the number of our brain cells begins to decrease at a speed of several million a year. They simply die off. In certain types of activity, the human brain is at its highest point in the early twenties, ... and we know that Albert Einstein made all his worldshaking discoveries between the age of about 20 and 25, and spent the rest of his life tidying them up and arranging them.” 人們發(fā)現(xiàn)，16歲以后，我們的腦細(xì)胞數(shù)量開始以每年幾百萬的速度減少。. is always a waste of time to make plans about the future is human nature to make attempts on what looks impossible should always challenge the impossible to push the society forward has to use wisdom in deciding what is the best thing to do【答案】 （1）B（2）A（3）D（4）D 【解析】【分析】本文是一篇說明文，介紹了人類的大腦在20歲左右于巔峰，在以后的成就多數(shù)是因為需要豐富的經(jīng)驗。 . helps to avoid various mistakes contributes to one39。 5．閱讀理解 （4）考查推理判斷。人工智能不可能像科學(xué)家,小說家和藝術(shù)家那樣進(jìn)行發(fā)明創(chuàng)造。結(jié)合下文推斷人工智能能夠具有取代人類的工作是因為AI在日常任務(wù)中表現(xiàn)超過了人類,劃線詞的意思是勝過,超過,故選A。而后文主要與人工智能有關(guān),由此推斷作者寫第一段的目的是引出人工智能這個話題。根據(jù)第一段可知一個名叫奈杰爾Upgrade people39。The psychologist.（4）Which of the following suggestions can the author give about job replacement of AI?

In fact 以及結(jié)合文章內(nèi)容主要介紹了微笑能夠讓我們放松進(jìn)而有利于我們的健康，所以要健康那就要多微笑，所以選B。故選A。根據(jù)最后一段中的“If we are smiling, we are breaking that link between stress and health. And it just may provide a little extra protection to everyone39。根據(jù)第三段中的“If you are truly in danger, these hormones can help you.”如果你真的有危險，這些荷爾蒙會幫助你。釋放出的化學(xué)物質(zhì)更積極。s opinion? has the same effects as laughter. can be used to take the place of medicine. is better than any healthy lifestyle to health. can make our body produce beneficial chemicals.（2）What can we know about the mentioned stress hormones? can lower our blood pressure. will surely lead to heart diseases. can benefit us when we are in danger. will make us live an unhealthy lifestyle.（3）Why does Dr. Chockalingam think smiling is helpful to our health? can make us relax. increases sugar levels. has little bad side effects. can happen for no reason.（4）What can be the best title for the text?

A warming ocean loses oxygen for two reasons: First, the warmer a liquid bees, the less gas it can hold. That is why carbonated drinks go flat faster when left in the sun. Second, as polar sea ice melts, it forms a layer of water above colder, more salty sea waters. This process creates a sort of lid that can keep currents from mixing surface water down to deeper depths. And because all oxygen enters the surface, less mixing means less of it at dep
