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.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 appea
3、rance.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
4、trend.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 oce
5、ans 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
6、 riper for phytoplankton,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,
7、Dutkiewicz said,“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
8、 before we can statistically 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 patte
9、rns at 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 ca
10、n we 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
11、.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.完形填空When I was diagnosed with breast cancer a few years back,I reacted like most who receiv

25、,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.A词义猜测题。根据画线词后的“Warmingchangeskeycharacteristicsoftheoceanandcanaffectphytoplanktongrowth.”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.D细节理解题。根据第四段的“Butinsomewaters.awarmingwillmakeconditionsriperforphytoplankton,andtheseareaswillturngreener.”可知在某些海域,气候变暖给浮游生物提
26、供更成熟的条件,而这些水域将会变得更绿。所以选D项。4.C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。.【解题导语】本文是一篇夹叙夹议文。作者身患癌症,但没有抱怨,而是通过写诗歌和小说来阐述人生,最终战胜了病魔。1.A上文说,作者对于患上癌症首先想到的是“死亡判决”;下文说,作者并没有抱怨。据此可以判断,空处前后文之间是转折关系,故A项正确。2.D根据该句中的insteadofcomplaining可知,作者没有选择抱怨而是决定寻找癌症积极的一面;positive意为“积极的”,符合语境。3.C根据语境可知,作者将面对新
27、的开始。face意为“面对,面临”,符合语境。4.B根据该句中的fromallmyexperiences可以判断,作者决定从自己的经历中获得战胜癌症的力量;strength意为“力量”,符合语境。5.D根据该句中的withthepain可知,作者要忍受癌症的痛苦;bear意为“忍受”,符合语境。6.B根据该句中的“Ivedealtwithallmylife.”并结合前文作者对患癌症的叙述可以判断,struggle意为“挣扎”,符合语境。7.C根据语境可知,作者提醒自己,自己仍然活着;remind意为“提醒”,故C项正确。persuade意为“说服”;show意为“展示”;teach意为“教”。
28、8.A根据上文第一段最后一句中的complaining并结合语境可知,A项正确。encourage意为“鼓励”;disappoint意为“失望”;please意为“取悦”。9.A根据下文的Itookthatpoem可知,作者将那次经历写成了一首诗;poem意为“诗歌”,符合语境。10.C根据上句中的Writing可以判断,这些诗是作者在患癌症期间写的,故C项正确。11.B根据该句中的enoughtohavethatbookpublished可以判断,作者足够幸运,出版了自己的诗集,故B项正确。confident意为“自信的”;careful意为“仔细的”;shocked意为“震惊的”。12.A
