23、cause of the way light reflects off the organisms，these 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
24、 other spots，leading to changes in the oceans appearance.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
25、 phytoplankton are vulnerable to the oceans warming 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，bui
26、lt a climate model that projects changes to the oceans 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
27、 those of the Arctic，a warming will make conditions 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 we
28、b.If certain kinds begin to disappear from the ocean，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，bu
29、t they could mean significant changes.“Itll be a while 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.”文章大意：本文是一篇说明文。
30、调查表明，由于气候变暖，全球的海洋将会变得更蓝、更绿。1. What are the first two paragraphs mainly about？ B AThe various patterns at the ocean surface.BThe cause of the changes in ocean colour.CThe way light reflects off marine organisms.DThe efforts to fuel the growth of phytoplankton.解析：段落大意题。文章第一段点题：由于气候变暖，全球的海洋将会变得更蓝、更绿。第二
31、段介绍由于光从生物体反射的方式，这些浮游植物在海洋表面形成了五颜六色的图案；气候变化又使得这些浮游植物在某些区域加速生长而在其他地方有所减少，导致海洋表面的颜色变化。由此可知前两段讲了海洋颜色变化的原因，故B项正确。2. What does the underlined word“vulnerable”in Paragraph 3 probably mean？ A ASensitive. BBeneficial.CSignificant. DUnnoticeable.解析：词义猜测题。后一句提到，气候变暖改变了海洋的主要特点并能影响浮游植物的生长，因为它们要生长不仅仅需要阳光和二氧化碳，也需要
32、营养。由此可知，这些浮游植物对海洋变暖很敏感，故A项正确。3. What can we learn from the passage？ D APhytoplankton play a declining role in the marine ecosystem.BDutkiewiczs model aims to project phytoplankton changes.CPhytoplankton have been used to control global climate.DOceans with more phytoplankton may appear greener.解析：推理
33、判断题。文章倒数第二段提到这些浮游植物是海洋食物链的基础，如果某些种类的浮游植物消失了，会影响能存活的鱼的类型，从而影响海洋食物链，所以A项“浮游植物在海洋生态中所起的作用越来越小。”是不对的；Dutkiewicz的模型不是用来推断浮游植物的变化的，而是推断海洋的变化的，排除B项；浮游植物不是用来控制全球气候的，排除C项。由文章第四段信息“But in some waters，such as those of the Arctic，a warming will make conditions riper for phytoplankton，and these areas will turn g
34、reener.”可知浮游植物多的区域海水会变得更绿，故D项正确。4. What is the main purpose of the passage？ C ATo assess the consequences of ocean colour changes.BTo analyse the composition of the ocean food chain.CTo explain the effects of climate change on oceans.DTo introduce a new method to study phytoplankton.解析：主旨大意题。文章主要论述了
35、随着气候变暖，全球的海洋将会变得更蓝、更绿，即气候变化对海洋有影响，故C项正确。BScientists in Argentina have created the worlds first cow to own two human genes that will enable it to produce humanlike milk, which is matchless up to now.It is a breakthrough in the area of clone.Genetic engineering was used to introduce the “mothers milk”
36、 genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.As an adult, the cloned cow “will produce milk that is similar to that of humans”， which will prove “a development of great importance for the nutrition of infants”， as it is said in a

39、because she weighed around 100 pounds, roughly twice the normal weight of Jersey cows.Adrian Mutto, from the National University of San Martin said, “Our goal was to raise the nutritional value of cows milk by adding two human genes, the protein lactoferrin and lysozyme，which can provide newlyborn b

41、t what woman would like to have a cow named after her? It appeared to me to be more appropriate to call it Rosita.”文章大意：文章介绍了阿根廷科学家通过添加人类基因的方式培育出了能生产“类人乳”的牛。这是基因工程的一项突破。5. What can we know about Rosita ISA according to the passage？ A AIts milk has larger nutritional value than others.BIt is the firs
42、t cow with a human gene.CIt is as heavy as Jersey cows.DIts milk has the same proteins as human breast milk.解析：推理判断题。根据文章第一段第一句“.the worlds first cow to own two human genes.”可知，B项中的a human gene错误；根据第七段“.twice the normal weight of Jersey cows.”可知C项错误；根据第六段“.the milk will more closely resemble that of
43、 humans.”可知，这种奶只是与母乳相似，故D项错误；根据第四段可知，该克隆牛所产牛奶和母乳相似，而且根据倒数第二段可知，它所产的奶在提供婴儿所需的营养方面有重大的进步。故选A项。6. Lactoferrin and lysozyme in milk D .Acan offer more proteins in cow milkBhelp provide more milk from cowCcan increase the production of milkDare good for babies health解析：推理判断题。根据文章倒数第二段中的“.the protein lact
44、oferrin and lysozyme，which can provide newlyborn babies with antibacterial and antiviral(抗病毒) protection.”可知，牛奶中的乳铁蛋白(lactoferrin)和溶菌酶(lysozyme)可以为婴儿提供抗菌和抗病毒的保护，对婴儿的健康有好处。故选D项。7. We can infer from the last paragraph that C .Ait is hard to name the cowBthe president wants the cow named after herChono
45、rable as it is, no women like the cow named after themDCristina Kirchner objects to creating the cloned cow解析：推理判断题。根据文章最后一段第三句“.but what woman would like to have a cow named after her？”可知，该反问句表示肯定意义，表示没有一个女人愿意一头牛跟自己姓。故选C项。8. What would be the best title of the passage？ B AScientists in Argentina Co
46、uld Produce Human MilkBScientists Create a Cow That Produces “Human” MilkCThe Cloned Cow Would Bring About BenefitsDHow Was the Cloned Cow Born?解析：标题归纳题。文章第一段第一句提出“Scientists in Argentina have created the worlds first cow to own two human genes that will enable it to produce humanlike milk，which is
47、matchless up to now.”，下文围绕该主题进行阐述。由此可知，本文主题是科学家培育出了一头能生产“类人乳”的牛。故选B项。.短文改错假定英语课上老师要求同桌之间交换修改作文，请你修改你同桌的以下作文。文中共有10处错误，每句中最多有两处。错误涉及单词的增加、删除或修改。增加：在缺词处加一个漏词符号()，并在此符号下面写出该加的词。删除：把多余的词用斜线()划掉。修改：在错词下面画一横线，并在该词下面写出修改后的词。注意：1.每处错误及其修改均仅限一词；2只允许修改10处，多者(从第11处起)不计分。(2019全国卷)I became interesting in playing

51、classmates after school.I am a good player now.文章大意：本文是一篇记叙文。文章讲述了作者因为一次小“意外”而喜欢上足球运动的故事。解析：1考查形容词。become interested in“变得对感兴趣。”2考查定语从句。one afternoon是表示时间的名词，后面的定语从句应用when引导。3考查冠词。此处是泛指“一个足球”，应用不定冠词a。4考查连词。“一个足球正好落在我面前”与“差点儿打到我”之间是顺承关系，故用并列连词and。5考查副词。此处表示“用力把足球踢回操场”，应用hard(adv.用力地)。hardly意为“几乎不”。6考查固定搭配。to ones surprise“令某人惊讶的是”。7考查名词的数。根据前面的all可知，player应用复数形式players。8考查非谓语动词。分析句子结构可知，cheered是谓语动词，say前没有并列连词and等，所以say只能用非谓语动词形式，主语与say之间是主动关系，故用现在分词短语作状语。9考查句意。文章讲述的是过去发生的事情，应该用from then on，意为“从那时起”。from now on意为“从现在起”。10考查固定搭配。play football“踢足球”。
