Today, the whole picture of this phenomenon still remains 10．________ (explore)．【语篇解读】本文是一篇科普说明文。主要讲了一项新的研究发现了一个有趣的现象： 哥哥会影响弟弟妹妹的语言发展。1．comes　考查时态。句意：然而，一项新的研究发现了一个有趣的缺点： 如果有一个哥哥，他的弟弟妹妹的语言发展就会很差。分析“with an older brother 1．________ (come) the poor language development of his younger siblings ”句子结构可知，介词短语放在句首，句子要用倒装结构，真正的主语是 “the poor language development of…”，是一个单数主语，结合上下文，时态用一般现在时，根据主谓一致原则可知。填comes。2．is linked　考查被动语态。句意：这项研究基于一些研究，这些研究表明，有年长的兄弟姐妹与语言发展不良有关。分析“having older siblings 2．________(link) with poor language development. ”的句子结构可知空格处填谓语，主语having older siblings与link之间是被动关系，结合语境和主谓一致原则可知。故填is linked。3．difficulties　考查名词。句意：现在研究人员得出了一个更具体的结论： 只有那些有哥哥的孩子表现出这些语言障碍。空格前有指示代词these，可知空格处要填复数名词。故填difficulties。4．designed　考查非谓语动词。句意：研究人员研究了1000多名儿童，从出生到5岁半。 每个孩子的语言能力分别在2岁、3岁和5．5岁时进行测试，使用专门设计的测试来衡量语言发展的许多方面。分析“using tests specially 4．________ (design)to measure numerous aspects of language development”这一部分的结构可知，“specially 4．________ (design)”是tests一词的后置定语，名词tests 与design之间为被动关系，所以用过去分词形式。故填designed。5．What　考查主语从句。句意：他们的发现意义重大……分析“5．________ they discovered was significant”句子结构可知，was之前是主语部分，主语部分是一个缺少宾语的主语从句，缺少的宾语，指物。故填What。6．on　考查介词短语。句意：……那些有哥哥的孩子，他们的语言发展平均会延迟两个月。average一般与介词on连用构成固定短语on average，意为“平均”。故填on。7．forward/forth/up　考查介词。句意：……研究人员提出了两个假设。没有提示词，考虑填冠词、介词、代词等，put为动词，考虑填介词，结合语境可知，此处要表达“提出”这一含义，put与介词forward/forth/up连用均有“提出”的意思。故填forward/forth/up。8．One　考查不定代词。句意：一是姐姐比哥哥说话更频繁……根据下文“the other…”可知此处考查固定短语one…， the other… “一个……，另一个……(一方面……另一方面……)”。故填One。9．less　考查形容词的比较级。句意：另一个原因是姐姐们通常不像哥哥们那样与兄弟姐妹争夺父母的注意力。根据空格后的than可知此处要填形容词的比较级。故填less。10．to be explored考查非谓语动词。句意：直到今天，这种现象的全貌仍有待探索。remains为谓语，则空格处填非谓语动词，表示去做将要做的事用非谓语的to do形式，this phenomenon与 explore是逻辑上的被动关系，故要用to do被动形式to be done。故填to be explored。Ⅱ. 阅读理解By the end of the century, if not sooner, the world’s 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 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 ocean’s appearance. Phytoplankton live at the ocean surface, where they pull carbon dioxide 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 ocean’s 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 MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century.  In a world that warms up by 39℃， 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 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, 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.  “It’ll 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. ”(　　)1． What directly makes the change of the ocean’s appearance?A．The increase of phytoplankton. B．The way light reflects off the organisms. C．The type and concentration of phytoplankton. D．The decline of phytoplankton. (　　)2． What does the underlined word “projects” in Paragraph 4 probably mean?A．Control. 　 B．Use. C．Predict. D．Discover. (　　)3． What can we learn from the passage?A．Phytoplankton are sensitive to the ocean’s warming trend. B．Phytoplankton absorb carbon dioxide at the bottom of the ocean. C．Oceans with more phytoplankton may appear bluer. D．Data have been found to show the change in the colour of the ocean. (　　)4． What is the main purpose of the passage?A．To introduce a new method to study phytoplankton. B．To explain the effect of climate change on oceans. C．To analyze the consequences of ocean colour changes. D．To analyze the composition of the ocean food chain. 【语篇解读】本文为一篇说明文。一项最新研究表明，由于气候变暖，世界海洋将会变得更蓝、更绿。这一现象的原因是因为一种叫作浮游植物的微小海洋微生物，因为光线反射的作用，它们在海洋表面形成了五颜六色的图案，现在浮游植物受到海洋变暖趋势的影响，让浮游植物的生长更加旺盛，所以海洋相应会变得更蓝、更绿。1．C　细节理解题。根据第二段中的“ Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. ”可知海洋的颜色从绿色到蓝色不等，取决于浮游植物的种类和浓度。故选 C项。2．C　词义猜测题。根据下文 “The model projects that currently blue areas with little phytoplankton could become even bluer. ”可知，杜基维奇的模型预测，目前只有少量浮游植物的蓝色区域可能会变得更蓝。因此推断划线句句意：麻省理工学院全球变化科学中心的科学家斯蒂芬妮·杜基维奇建立了一个气候模型，预测整个世纪海洋的变化。故划线词词义与predict意思相近。故选C项。3．A　细节理解题。根据第三段的 “But phytoplankton are vulnerable to the ocean’s warming trend. ”可知，浮游植物很容易受到海洋变暖趋势的影响，也就是很敏感。故选A项。4．B　推理判断题。第一段提出文章的主旨 “By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study. ”可知，一项新的研究表明，到本世纪末，由于气候变暖，如果不尽快的话，世界上的海洋将会变得更蓝、更绿，接下来详细讲述了原因。因此推断写作目的是解释气候变化对海洋的影响。故选B项。Ⅲ. 书面表达假定你是李华， 上周日你校举办了5公里越野赛跑活动。请你为学校英文报写一篇报道。内容包括：1． 参加人员；2． 跑步路线：从校门口到南山脚下；3． 活动反响。注意：1． 写作词数应为80左右；2． 请按如下格式在相应的位置作答。A Cross-Country Running Race________________________________________________________________________________________________________________________________________________________________________________________________________________________________________One possible version：A Cross-Country Running RaceLast Sunday witnessed an extraordinary cross-country running race, which nearly drew the attention of every student and teacher of our school. The students selected from every class took part in the competition. The route measured five kilometres, from our school gate to the foot of Nanshan Mountain. Every runner tried their best to finish the task, with their classmates along the way giving them necessarily help as well as encouragement. At last, all the runners managed to arrive the finish line, receiving cheers from all the directions. The activity was highly spoken of, because not only did it provide chance for us to exercise, but also made us more cohesive.
