1、考点规范练29.阅读理解(2019北京)By 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,t
2、hese phytoplankton create colourful patterns at the ocean surface.Oceancolour 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 appear
3、ance.Phytoplankton live 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 tr
4、end.Warming changes key 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 ocean
5、s throughout the century.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 r
6、iper for phytoplankton,and these areas will turn greener.“Not only are the quantities of phytoplankton in the ocean changing,”shesaid,“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,Dut
7、kiewiczsaid,“it will change the type of fish that will be able to survive.”Those kinds of changes could affect the food chain.Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable,but they could mean significant changes.“Itll be a while bef
8、ore we can statistically show that the changes are happening because of climate change,”Dutkiewiczsaid,“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 a
9、t the ocean surface.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.2.What does the underlined word“vulnerable” in Paragraph 3 probably mean?A.Sensitive.B.Beneficial.C.Significant.D.Unnoticeable.3.What can we
10、learn from the passage?A.Phytoplankton play a declining role in the marine ecosystem.B.Dutkiewiczs model aims to project phytoplankton changes.C.Phytoplankton have been used to control global climate.D.Oceans with more phytoplankton may appear greener.4.What is the main purpose of the passage?A.To a
11、ssess the consequences of ocean colour changes.B.Toanalyse 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.完形填空Jayce Crowder began noticing when he was in kindergarten that he looked different from his cl

30、可知,和Jayce一样,TrashaunWillis左臂的大部分也是缺失的(missing)。rise“上升”;fail“失败”;cover“覆盖”。9.A根据空后的watchingonedunkafteranother可知,Jayce被TrashaunWillis的扣篮视频深深吸引(attracted)。10.B上文说到Trashaun身体虽有残疾却能够扣篮,因此对Jayce来说,当时观看Trashaun的视频是一个鼓舞人心的(inspiring)时刻。11.C但是Lewis几乎不知道(know),她的一位朋友已经联系(contact)了DesMoinesRegister。pay“付钱”;m
