二、语法填空：阅读短文，在空格处填入一个适当的词或用所给单词的适当形式填空(本大题共20小题，每小题1.5分，共30分) Passage 1 Like other big cities, Paris has also a traffic problem: lots of cars, traffic jams and traffic pollution. So since 2007, the city ____1____(start) a plan to improve the situation. Under a project, people can take a bicycle, use it as long as they want, and then leave it at the same or another bicycle station. The first half-hour is free, ____2____ if you don’t return it after 30 minutes, you have to pay. It’s only $1 or $29 a year. The bicycles are as heavy as 25 kilograms, and they’re all grey and have baskets. There’re a large number of ____3____(they) in the city, and the bicycle stations are more than the subway stations! Paris isn’t the first city to operate a project like this. One Parisian said, “These bicycles are only suitable for short ____4____(journey). If people want to travel across the city, they won’t use a bicycle — they’ll still use their cars.” A city spokesman said, “The bicycle project won’t solve all our traffic problems, but it might work in ____5____(reduce) air pollution. Traffic, together with factory fumes, ____6____(be) a big problem. Everyone knows about global warming and dramatic climate changes — we know this is partly because rainforests are ____7____(gradual) disappearing. And it’s also because there’s so much pollution. There aren’t any simple answers ____8____ traffic problems and pollution in cities, but the bicycles might help people lead ____9____ healthier life. Unless we do something now, there’ll be more traffic jams and temperatures will continue to rise, so the problems in our environment will get even ____10____(bad).” 【答案】 1．has started 2．but 或yet 3．them 4．journeys 5．reducing 6．is 7．gradually 8．to 9．a 10．worse 【分析】本文是一篇说明文。主要介绍了一种新的自行车骑行方案，鼓励人们为了环境和自己的身体健康，多骑自行车。 1．考查动词时态。句意：因此，自2007年以来，该市开始了一项改善现状的计划。根据上文since 2007可知应用现在完成时表达现阶段已经完成的动作，since和现在完成时态连用。故填has started。 2．考查并列连词。句意：第一个半小时是免费的，但如果30分钟后不归还，就得付费。根据语境可知上下文为转折关系，故填but或yet。 3．考查人称代词。句意：在城市里有很多这样的人，而且自行车站比地铁站还多！of为介词后跟人称代词宾格形式做宾语，故填them。 4．考查名词的数。句意：这些自行车只适合短途旅行。journey为可数名词，前面没有冠词修饰，故填复数形式journeys。 5．考查非谓语动词。句意：自行车项目不会解决我们所有的交通问题，但它可能在减少空气污染方面发挥作用。介词in 的宾语用动名词，故填reducing。 6．考查主谓一致。句意：交通和工厂的烟雾是一个大问题。当句子中together with ，along with ，with，as well， except等介词短语存在时，谓语动词单复数要和第一个主语的单复数保持一致，本句主语为Traffic。故谓语动词用第三人称单数。故填is。 7．考查副词。句意：每个人都知道全球变暖和剧烈的气候变化——我们知道这部分是因为雨林正在逐渐消失。修饰动词disappear应用副词，故填gradually。 8．考查介词。句意：对于城市中的交通问题和污染，没有任何简单的答案。短语answers to problems“问题的答案”，故填to。 9．考查冠词。句意：自行车可以帮助人们过上更健康的生活。life为可数名词，此处表示泛指“一个生活”，故填a。 10．考查形容词比较级。句意：除非我们现在采取行动，否则将会有更多的交通堵塞，气温将继续上升，所以我们的环境问题将会变得更糟。根据句意以及上文even可知应填形容词比较级worse，表示“更糟；更坏”。 【点睛】语法填空是通过语篇在语境中考查语法知识的运用能力，在解题前应快速浏览短文掌握大意，在读懂短文的基础上，结合短文提供的特定的语言环境去逐句分析。要解决好语法填空，离不开坚实的语法知识，有了坚实的语法知识才能对语言进行正确的分析和判断，从而答对题目。本篇语法填空考查到的语法知识有时态、词性、非谓语动词等。例如小题1考查时态。根据上文since 2007可知应用现在完成时表达现阶段已经完成的动作，since和现在完成时态连用。故填has started。 Passage 2 Language is sometimes written as a code so that people can communicate secrets. During ____1____ Second World War, the German Navy （海军）used a code to send messages. The British broke the code and ____2____ （learn） about many German plans. The Japanese also used a code to talk to ____3____ （they） ships at sea. It was called the Purple Code. Although the Americans soon broke this code, the Japanese didn’t know it ____4____（break）. In 1942 , the Americans began to use their own code to send ____5____ （secret）. A few Navajo（纳瓦在人）Indians made this code ____6____（base） on their language, which only some American Indians spoke. The code described a few things the American army did. Only they could understand this code, so they went with the army as it fought against the Japanese. These Navajo soldiers promised ____7____（keep） this code a secret, even though this could cause their ____8____（die）. The Japanese never broke the code because they knew nothing ____9____ the Navajo language. And the code, ____10____ connected two languages, helped win the war in the Pacific. 【答案】 1．the 2．learned/learnt 3．their 4．had been broken 5．secrets 6．based 7．to keep 8．deaths 9．about 10．which 【分析】本文是一篇说明文，主要介绍了二战时期不同国家使用的一些语言密码。 1．考查冠词。此处特指第二次世界大战，序数词前面要用定冠词 the。故填the。 2．考查时态。根据前文During the Second World War可知是过去发生的事情，所以此处用一般过去时learned/learnt。故填learned/learnt。 3．考查代词。此处表示日本人也用密码跟他们的船只交流，修饰名词ships应用形容词性物主代词their。故填their。 4．考查时态及语态。根据前文Although the Americans soon broke this code, the Japanese didn’t know it可知，美国人破解了密码，但日本人不知道密码已经被破解了。break动作发生在didn’t know之前，故本空应用过去完成时，且根据语境可知此处应用被动语态，故填 had been broken。 5．考查名词复数。根据语境可知美国人用密码传递秘密，秘密不可能是一个，应用复数 secrets。故填secrets。 6．考查过去分词。此处指一些纳瓦霍印第安人以他们的语言为基础创造了密码。be based on意为“以……为基础”，本空应用过去分词based。故填based。 7．考查不定式。promise to do sth. 意为“承诺做某事”，本空应用to keep作宾语。故填to keep。 8．考查名词复数。设空处作动词cause的宾语，并且被形容词性物主代词their修饰，所以用名词复数。故填deaths。 9．考查介词。根据语境可知，他们对纳瓦霍印第安人的语言一无所知。know nothing about...意为“对……一无所知”，本空应介词 about。故填about。 10．考查定语从句的关系词。此处引导非限制性定语从句，先行词为the code, 关系词在从句中作主语，应用which。故填which。 1 / 1乐思英语 学科网（北京）股份有限公司 $考前特训 高一下（Book2-3）期末考之核心语法综合练习（人教版） 内容提要 单句语法填空题 完成句子填空题 语篇语法填空题 班级 姓名 学号 分数
