31、 been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you？” asked Jamie Taylor of the Wave Energy Group at University of Edinburgh “There is certainly a lot of energy in waves，” he said Scientists are working to use that e

32、nergy to make electricity Most waves are created when winds blow across the ocean “The wind starts out by making little ripples (漣漪), but if they keep on blowing, those ripples get bigger and bigger and turn into waves，” Taylor said “Waves are one of natures ways of picking_up energy and then sendin

33、g it off on a journey” When waves come toward the shore, people can set up dams to block the water and send it through a large wheel called a turbine (渦輪機(jī)) The turbine can then power an electrical generator to produce electricity“The resource is huge，” said Janet Swain of the Worldwatch Institute “W

34、e will never run out of wave power” Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal Oceans cover three quarters of the Earths surfacethat would make wave power seem ideal for creating energy throughout the world, though there are some weak points

35、yet to overcomeSwain said that wave power still costs too much money She also said that its effects on sea animals are still unknown What is more, wave power could affect fishing and boat traffic Traditional sources of energy like oil and gas may someday run out “Demand for energy to power our TVs a

36、nd computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world，” Swain said In the future when you turn on a light, an ocean wave could be providing the electricity!13The writer uses the two questions at the beginning of the passage to _Atest the readers knowledge a

37、bout wavesBdraw the readers attention to the topicCshow Jamie Taylors importanceDinvite the readers to answer them答案：B推理判斷題。作者在問題后談到了波浪能源的相關(guān)內(nèi)容，所以文章開頭的兩個(gè)問句是為了引起讀者的注意，從而引出文章主題。故選B。14The underlined phrase “picking up” is closest in meaning to “_”Astarting again Bspeeding upCimproving Dgathering答案：D詞義猜測

38、題。本句中的“and then sending it off on a journey”是關(guān)鍵信息，it指代energy, send off意為“把發(fā)散出去”，由此可知，前一動(dòng)作是收集能源的過程。故picking up在此意為“收集”，與gathering同義。故選D。15It can be inferred that someday we might not worry about _ Aour power supply Bour boat traffic Cair pollution Dour supply of sea fish答案：A細(xì)節(jié)理解題。由第二段前兩句可知，資源很龐大，所以將來

39、終有一天我們不必再為電力供應(yīng)擔(dān)憂。never run out of “永遠(yuǎn)不會(huì)用完”是關(guān)鍵信息。故選A。16We can make better use of wave energy if we _ Ashorten its journey to thousands of homes Bbuild more small power stations on the oceans Creduce the cost of turning it into electric power Dquicken the steps of producing electricity答案：C細(xì)節(jié)理解題。根據(jù)第三段第

40、一句“Swain said that wave power still costs too much money”可知，波浪能源仍耗資很多。由此可知，如果我們能降低波浪能源的發(fā)電成本，我們將會(huì)更好地利用波浪能源。故選C。A限時(shí)8分鐘(2019成都市高中畢業(yè)班摸底測試)As evolution tends to remove waste，how come we evolved such large, energyconsuming brains? The dominant hypothesis (假設(shè)) suggests that tough social interactions are th

41、e driving force But our new study done in an unusual way shows that human brain expansion is likely driven by ecology (生態(tài)) Scientists have tested the ecological and social hypotheses before The common approach is to look at many species and investigate whether large brains are associated with specif

42、ic problems For example, do primates or other animals with large brains have a diet that is challenging to find but nutritionally rewarding? This would indicate an ecological origin Or do they live in large groups where they face lots of social problems? While many studies have found such associatio

43、ns, there is a problem It cannot tell whether large brains evolved to solve the difficult problems or whether they evolved for other reasons and then enabled their bearers to deal with the hard problemsTo find out the causes of brain expansion, we recreated the scenarios (可能出現(xiàn)的情況) of the two hypothe

44、ses using a mathematical model We found that a combination of ecological and social challenges do produce the brain size we see in humans But it was ecological challenges that expanded brains In contrast to the dominant view and our own expectation, we found that social challenges contributed by dec

46、rains? We found that ecological problems only lead to humansized brains when individuals can keep learning hard skills as they grow So our results and those of others suggest that hard ecology and the accumulation of cultural knowledge could act together to produce a humansized brainWill the human b

The complexity of the systems involved makes it impossible to say much with certainty at present1In most peoples view, what makes human evolve large brains?ASocial challengesBSocial and ecological challengesCEcological challengesDCompetition with other large animals答案：A細(xì)節(jié)理解題。根據(jù)第

48、一段第二句“The dominant hypothesis (假設(shè)) suggests that tough social interactions are the driving force”并結(jié)合第一段內(nèi)容可知，大部分人認(rèn)為棘手的社會(huì)交往活動(dòng)是人類大腦進(jìn)化的動(dòng)力，故A項(xiàng)正確。2Whats the problem of the common approach?AIts model is not reliable enoughBIt doesnt tell the cause and effect clearlyCIts hypothesis cannot be proved effectiv

49、elyDIt doesnt find brain size is connected with problems答案：B細(xì)節(jié)理解題。根據(jù)第三段第二句“It cannot tell whether large brains evolved to solve the difficult problems or whether they evolved for other reasons and then enabled their bearers to deal with the hard problems”可知，傳統(tǒng)的研究方法無法解釋清楚大腦進(jìn)化的原因和影響，故B項(xiàng)正確。3Why dont ma

50、ny animals have large brains?AThey dont learn from each otherBThey dont face hard ecological problemsCThey dont need to cooperate with each otherDThey dont keep learning tough skills as they grow答案：D推理判斷題。根據(jù)第五段第二、三句“Why dont they all have large brains? We found that ecological problems only lead to

51、humansized brains when individuals can keep learning hard skills as they grow”可知，只有當(dāng)個(gè)體在成長過程中不斷學(xué)習(xí)艱難的技能時(shí)，生態(tài)環(huán)境才會(huì)導(dǎo)致人類特定大小的大腦。據(jù)此可以判斷，動(dòng)物在成長過程中并沒有持續(xù)學(xué)習(xí)艱難的技能，所以動(dòng)物沒有大的大腦，故D項(xiàng)正確。4Which of the following do the researchers find most surprising?AAnimals dont have large brainsBSocial challenges decrease brain sizeC

52、Ecological challenges increase brain sizeDIts unclear whether human brains will expand further答案：B細(xì)節(jié)理解題。根據(jù)第四段第四句“In contrast to the dominant view and our own expectation, we found that social challenges contributed by decreasing brain size”可知，與主流觀點(diǎn)及我們自己的預(yù)期相反，我們發(fā)現(xiàn)社會(huì)挑戰(zhàn)導(dǎo)致大腦變小。據(jù)此可知，社會(huì)挑戰(zhàn)導(dǎo)致大腦變小是令人驚訝的發(fā)現(xiàn)，故B

53、項(xiàng)正確。B限時(shí)8分鐘調(diào)題庫4D篇，序號與A篇順排(2019合肥市高三調(diào)研性測試)Babies teach their older brothers and sisters empathy (共鳴), according to a new study Empathy means understanding and entering others feelings Until now, younger kids have generally been regarded to learn plenty from their older brothers or sisters but dont giv
