【正文】 （3）What is the significance of the research? A.To show how wolves benefit from ecosystems.C.Accept.（2）For what purpose was a documentary made? A.Notice.Understand.Expect. To learn more about just how wolves are beneficial, a short documentary from Quest explains how the presence of wolves influences the behavior of deer, which eventually makes entire ecosystems more biologically diverse and healthy. In this documentary, biologist Aaron Wirsing explored why wolves and other top predators （捕食者）were needed for diverse ecosystems to develop. Using a simple video camera, Wirsing is gaining a unique view point on predatorprey relationships and changing the way we think about wolves.t adopted ecologicalprocess management—allowing natural ecological processes to take place with least human intervention. Yellowstone has benefited from the reintroduction of wolves in ways that we did not anticipate, especially the plexity of biological interactions（互動(dòng)） in the park, explained Mark Boyce, a professor in the Department of Biological Sciences. We were really surprised at that and we39。 Wolves strike fear into the hearts of many species, humans included. Our fear of them has brought them to the edge of dying out, as we have cruelly killed them as petitors and troublemakers. But researchers are discovering that the very fear they put into prey（被捕食者）species is exactly what helps make ecosystems（生態(tài)）healthy. 【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。可能有更多的人受到無形的傷害。 （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, ideally before the ocean turns into a thin soup of plastic. （1）Why does the author mention the Pilgrims in paragraph 1?

Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly, stuck by abandoned things made of plastic. Many more are probably harmed invisibly. Marine species of all sizes, from zooplankton to whales, now eat microplastics, the bits smaller than onefifth of an inch across.s last sink.

Of that, more than billion tons have bee waste. And of that waste, a surprising billion tons never made it to a recycling binthe figure that shocked the scientists who published the numbers in 2017.s oceans today, waiting to be eaten by some fish or oyster, and finally perhaps by one of us.4．犇犇閱讀理解 故選B。 （4）考查主旨大意。根據(jù)倒數(shù)第三段中的“had better attention and shortterm memory ”可知，Stephen Kaplan的研究發(fā)現(xiàn)親近大自然可以提高注意力和短期記憶力，也就是說提高了大腦的工作效率。故選A。 （2）考查推理判斷。他完全沉浸在大自然之中。 （1）考查細(xì)節(jié)理解。s as it should be.（1）What is Kang Byoungwook doing? lost in nature. up his strength. to control a forest fire. firefighters under stress.（2）What does Lisa Nisbet think of being outdoors? is overlooked by people. has nothing to do with happiness. Koreans show great interest in it. need more evidence for its benefits.（3）What benefit of nature did Stephen Kaplan find? affects people39。s more surprising is that nature may also make us more creative. David Strayer, a psychologist at the University of Utah, showed as much with a group of participants, who performed 50 percent better on creative problemsolving tasks after three days of wilderness backpacking. Another experiment conducted by psychologist Stephen Kaplan found that people who took a 50minute walk in a park had better attention and shortterm memory than those who took a walk along a city street.t think of being outdoors as a way to increase happiness, says Nisbet. We think other things will, like shopping or TV. But South Korea is starting to challenge this opinion. There is increasing evidence that being outside in a pleasant natural environment is good for us. But how many of us get to enjoy nature regularly? Fewer and fewer, it seems. According to Lisa Nisbet, a psychology professor at Canada s Trent University, evidence for the benefits of nature is pouring in at a time when we are most disconnected from it. the firefighters all have posttraumatic stress disorder (創(chuàng)傷后應(yīng)激障礙). 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，詞義猜測，推理判斷和主旨大意四個(gè)題型的考查，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。根據(jù)第三段中的“Ullman says his research shows that the human brain does not have a special area or system for making language. Over time we have simply reused or coopted (指派) parts of our brain for language.”以及全文可知，人類的語言學(xué)習(xí)是由大腦前區(qū)完成的，該區(qū)域早于人類本身。所以it是指代using grammar patterns，故選C。 （3）考查詞義猜測。根據(jù)第六段中的And procedural motor memory is what we often call motor memory39。根據(jù)第五段中的“Ullman, Hamrick and the rest of the team looked at data from 16 other studies on language.”可知，該團(tuán)隊(duì)通過研究其他語言學(xué)習(xí)的成果，得出的結(jié)論，故選D。在最古老的大腦學(xué)習(xí)記憶區(qū)域，陳述性記憶和運(yùn)動(dòng)記憶分工合作，來完成語言學(xué)習(xí)。Learning memory is more active than motor memory.
