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。故選D。最重要的是了解人性，了解真實(shí)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。根據(jù)第三段中的“Besides sharpness of brain and experience, here is another thing that is very important, and that is wisdom.... 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.”除了敏銳的頭腦和豐富的經(jīng)驗(yàn)外，還有一件事是非常重要的，那就是智慧。故選A。根據(jù)第二段“But in certain other types of activity (of which being an author is perhaps one), experience is more important than sharpness of brain, and there one usually finds that a person reaches his or her peak much later in life.”但在某些其他類型的活動(dòng)中(作家可能是其中一種)，經(jīng)驗(yàn)比頭腦的敏捷更重要，人們通常會(huì)發(fā)現(xiàn)一個(gè)人在他一生的晚期才達(dá)到頂峰。根據(jù)對(duì)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。愛因斯坦在20到25歲之間做出了所有震驚世界的發(fā)現(xiàn)。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。人們要用智慧來決定做什么才是最好的。. 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?yàn)樾枰S富的經(jīng)驗(yàn)。 . helps to avoid various mistakes contributes to one39。 and what is possible but so difficult that it is not worth all the trouble one has to go through to get there.

A.Global warming reduces the amount of oxygen in the air.C.The lack of attention to the warming of tropical oceans.（2）Which of the following is a reason for the oxygen loss in the ocean? A.The survival of predators and various marine animals.C. Aside from food web problems, animals face various other physiological challenges as their bodies adjust to lower oxygen levels. Chinese shrimp (蝦) move their tails less vigorously to preserve energy in lower oxygen environments. Some creatures, such as jellyfishes, are more tolerant of low oxygen than others are. But all animals will feel the impact of deoxygenation because they all have evolved their oxygen capacity for a reason, says Oschlies. Any drop in oxygen is going to damage survivability and performance, he says.（1）According to the first two paragraphs, what worries scientists the most? A. 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 depth. Escaping predators (食肉動(dòng)物), digestion and other animal activities—including those of humans—require oxygen. But that essential ingredient is no longer so easy for marine life to obtain, several new studies reveal. 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解和推理判斷兩個(gè)題型的考查，是一篇環(huán)保類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，從而選出正確答案?？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。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(gè)必要的機(jī)構(gòu)和制度的問題，可推知選C。 （3）考查推理判斷?？赡苡懈嗟娜耸艿綗o形的傷害。 （2）考查細(xì)節(jié)理解。根據(jù)第一段中的“their plastic waste would likely still be around four centuries later.A lifestyle magazine.【答案】 （1）D（2）B（3）C（4）C 【解析】【分析】本文是一篇說明文，介紹了塑料垃圾給海洋以及海洋生物帶來的危害。A travel brochure.C.A biology textbook.s time to take measures to deal with plastic waste.D.Plastics will turn the ocean into a soup of plastic.C.Some people don39。D.Being caught by humans.B.Lacking protection.To show plastic waste has a lasting effect on the ocean.（2）What39。To introduce what marine animals like eating.C.s a matter of building the necessary institutions and systems, he says,
