4、the end of the century,if not sooner,the worlds oceans will be bluer and greener thanks to a warming climate,according to a new study.At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物) called phytoplankton.Because of the way light reflects off the organisms,these phytoplankton crea

5、te colourful patterns at the ocean surface.Ocean colour varies from green to blue,depending on the type and concentration of phytoplankton.Climate change will fuel the growth of phytoplankton in some areas,while reducing it in other spots,leading to changes in the oceans appearance.Phytoplankton liv

6、e at the ocean surface,where they pull carbon dioxide(二氧化碳)into the ocean while giving off oxygen.When these organisms die,they bury carbon in the deep ocean,an important process that helps to regulate the global climate.But phytoplankton are vulnerable to the oceans warming trend.Warming changes ke

7、y characteristics of the ocean and can affect phytoplankton growth,since they need not only sunlight and carbon dioxide to grow, but also nutrients.Stephanie Dutkiewicz,a scientist in MITs Center for Global Change Science,built a climate model that projects changes to the oceans throughout the centu

8、ry.In a world that warms up by 3 ,it found that multiple changes to the colour of the oceans would occur.The model projects that currently blue areas with little phytoplankton could become even bluer.But in some waters,such as those of the Arctic,a warming will make conditions riper for phytoplankto

9、n,and these areas will turn greener.“Not only are the quantities of phytoplankton in the ocean changing,”she said,“but the type of phytoplankton is changing.”And why does that matter?Phytoplankton are the base of the food web.If certain kinds begin to disappear from the ocean,Dutkiewicz said,“it wil

11、cally show that the changes are happening because of climate change,”Dutkiewicz said,“but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”1.What are the first two paragraphs mainly about?A.The various patterns at the ocean surfac

12、e.B.The cause of the changes in ocean colour.C.The way light reflects off marine organisms.D.The efforts to fuel the growth of phytoplankton.答案B解析主旨大意题。根据文章前两段的内容可知,这两段主要介绍了海洋颜色发生变化的原因。所以选B项。2.What does the underlined word“vulnerable” in Paragraph 3 probably mean?A.Sensitive.B.Beneficial.C.Significa

13、nt.D.Unnoticeable.答案A解析词义猜测题。根据下一句“Warming changes key characteristics of the ocean and can affect phytoplankton growth”可知,浮游生物容易受到气候变暖的影响,vulnerable的含义与sensitive最为接近。所以选A项。3.What can we learn from the passage?A.Phytoplankton play a declining role in the marine ecosystem.B.Dutkiewiczs model aims to

14、project phytoplankton changes.C.Phytoplankton have been used to control global climate.D.Oceans with more phytoplankton may appear greener.答案D解析细节理解题。根据第四段第四句“But in some waters., a warming will make conditions riper for phytoplankton, and these areas will turn greener.”可知在某些海域,气候变暖给浮游生物提供更成熟的条件,而这些

15、水域将会变得更绿。所以选D项。4.What is the main purpose of the passage?A.To assess the consequences of ocean colour changes.B.To analyse the composition of the ocean food chain.C.To explain the effects of climate change on oceans.D.To introduce a new method to study phytoplankton.答案C解析写作意图题。通读文章的第一段以及最后一段的内容可知,作者

16、写这篇文章的主要目的就是解释气候变化对海洋的影响。所以选C项。BSince the 1970s,scientists have been searching for ways to link the brain with computers.Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.Recently,two researchers,Jose Milan and Michele Tavella from the Feder

17、al Polytechnic school in Lausanne,Switzerland,demonstrated(展示) a small robotic wheelchair directed by a persons thoughts.In the laboratory,Tavella operated the wheelchair just by thinking about moving his left or right hand.He could even talk as he watched the vehicle and guided it with his thoughts

18、.“Our brain has billions of nerve cells.These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move.But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,”Tavella says.“Our system allows disabled people to c

19、ommunicate with the external world and also to control devices.”The researchers designed a special cap for the user.This head cover picks up the signals from the scalp(头皮) and sends them to a computer.The computer interprets the signals and commands the motorized wheelchair.The wheelchair also has t

20、wo cameras that identify objects in its path.They help the computer react to commands from the brain.Prof.Milan,the team leader,says scientists keep improving the computer software that interprets brain signals and turns them into simple commands.“The practical possibilities that BCI technology offe

21、rs to disabled people can be grouped in two categories:communication,and controlling devices.One example is this wheelchair.”He says his team has set two goals.One is testing with real patients,so as to prove that this is a technology they can benefit from.And the other is to guarantee that they can

22、 use the technology over long periods of time.5.BCI is a technology that can .A.help to update computer systemsB.link the human brain with computersC.help the disabled to recoverD.control a persons thoughts答案B解析细节理解题。根据第一段可知,自20世纪70年代以来,科学家一直寻找途径能将人脑与电脑相连。BCI技术能帮助残疾人向机器发送指令。故此处B项正确。而C项只是部分正确,虽然能帮助残疾

23、人,但却不能帮他们康复。6.How did Tavella operate the wheelchair in the laboratory?A.By controlling his muscles.B.By talking to the machine.C.By moving his hand.D.By using his mind.答案D解析细节理解题。根据第三段可知Tavella只是思考动他的左右手就能操作这个轮椅。甚至当他观察这台机器时就能进行交流,也能用他的思想指导机器人工作。因此机器人是在人脑的思想支配下进行工作的。故D项正确。7.The team will test with r

24、eal patients to .A.make profits from themB.prove the technology useful to themC.make them live longerD.learn about their physical condition答案B解析推理判断题。根据最后一段第二句“One is testing with real patients,so as to prove that this is a technology they can benefit from.”可知,在患者身上进行实验是他们团队工作的一个目标,旨在证明这项技术对他们有益。故答案

25、选B项。8.Which of the following would be the best title for the text?A.Switzerland,the BCI Research CentreB.New Findings about How the Human Brain WorksC.BCI Could Mean More Freedom for the DisabledD.Robotic Vehicles Could Help to Cure Brain Injuries答案C解析主旨大意题。本文为科技说明文,开篇点题。介绍科学家研究的这项新技术BCI,对残疾人大有裨益。故答
