The train ________ for just a few minutes. A．has left B．left C．has been away from D．has been away 【答案】D 【详解】句意：——打扰一下，先生。我能赶上那趟去北京的火车吗？——恐怕不能。那趟火车已经刚开走几分钟了。 考查动词时态与动词辨析。has left离开，现在完成时；left离开，一般过去时；has been away from从……离开，现在完成时，延续性短语，需接地点；has been away离开，现在完成时，延续性短语。根据“...for just a few minutes”可知，此处需用现在完成时且动词为延续性动词，“has been away” 符合语境，故选D。 2.The famous writer ________ for over a hundred years, but his works still have great influence (影响) today. A．died B．has died C．was dying D．has been dead 【答案】D 【详解】句意：这位著名作家已去世一百多年，但他的作品至今仍有很大影响。 考查现在完成时的延续性动词用法。died死，过去式；has died死，现在完成时结构，瞬间性动作；was dying正在死，过去进行时结构；has been dead已经死了，现在完成时结构，延续性状态。根据“for over a hundred years”可知，此句时态为现在完成时，结构为have/has done，且需用延续性动词或状态。故选D。 3.— When will the men’s badminton team final begin? — Oh, it ________ for ten minutes, ending in 3:1. China won the game. A．has been on B．has started C．has been over D．has ended 【答案】C 【详解】句意：——男子羽毛球队决赛什么时候开始？——哦，它已经结束十分钟了，最终比分3:1。中国赢得了比赛。 考查现在完成时。has been on已经开始且一直在持续；has started表述有误；has been over已经结束；has ended表述有误。for ten minutes是一段时间，要与延续性动词连用。start和end是短暂性动词，其延续性形式分别为be on“进行”和be over“结束”。根据“China won the game”可知，比赛已经结束。故选C。 4.—Hello, may I speak to Wang Li? —Sorry, she is not at home. She ________ since a month ago. A．left B．has left C．has been away D．went away 【答案】C 【详解】句意：——你好，我可以和王丽通话吗？——对不起，她不在家。她已经离开一个月了。 考查现在完成时和延续性动词。根据“She ... since a month ago.”可知，此处应使用现在完成时，且表示延续性动作；leave是短暂性动词，对应的延续性动词是“be away”。故选C。 5.Hema Supermarket ________ for nearly a month. Let’s go shopping there. A．have opened B．has opened C．has been open D．has been on 【答案】C 【详解】句意：盒马超市已经开业近一个月了，我们去那里购物吧。 考查现在完成时的延续性表达。根据“for nearly a month”可知，此处应用现在完成时；open作动词时，是非延续性动词，不能与表示一段时间的时间状语连用，要改为延续性动词或表示状态的词；open作形容词时，表示状态，能与表示一段时间的时间状语连用，be open意为“营业的”。所以此处应为has been open。故选C。 E.单句语法填空 1.My grandparents have been (marry) for 50 years and they celebrated it last Sunday. 【答案】married 【详解】句意：我的祖父母已经结婚50年了，他们上周日庆祝了这个纪念日。 be married “结婚的，已婚的”，符合语境。故填married。 2.Mr. Sun Zhongshan has been for 100 years. (die) 【答案】dead 【详解】句意：孙中山先生已经去世100年了。根据“for 100 years”及提示词可知，此处的谓语要用延续性动词，die“死亡”是瞬间性动词，be dead是延续性形式。故填dead。 3.She (marry) him for 15 years, yet she still doesn’t know what kind of man he is. 【答案】has been married to 【详解】句意：她已经嫁给他15年了，但她仍然不知道他是个什么样的人。根据可知此处应用现在完成时“主语+have/has+done”，并且与一段时间连用，非延续动词“marry”需变为延续性动词“be married”，主语“She”是第三人称单数，助动词应用“has”，“be”需变为过去分词“been”，故此处“已经与某人结婚”has been married to sb。故填has been married to。 4.I (borrow) the magazine for two weeks. I’ll return it to the library tomorrow. 【答案】have kept 【详解】句意：我把这本杂志保存了两个星期。我明天会把它还给图书馆。根据“for two weeks”可知，本句时态为现在完成时，且句子和时间段连用，此处用延续性动词，borrow“借入”为短暂性动词，需用延续性动词keep，主语为I，助动词用have，keep的过去分词为kept。故填have kept。 5.I (join) the League for 5 years so far. 【答案】have been in 【详解】句意：到目前为止，我加入那个联合会已经五年了。此处与一段时间“for 5 years”连用，非延续动词“join”需变为延续性动词“be in”，根据“so far”可知此句应用现在完成时“主语+have/has+done”，主语是“I”，助动词应用“have”，“be”变为过去分词“been”。故填have been in。 八、语法填空 My topic today is about environmental protection. People 1 (do) a lot of things at the cost of the environment to develop the economy (经济) quickly in the past few years. I do think it is time for us to understand the 2 (important) of protecting the environment and do something about it. And today I would like 3 (introduce) some simple but useful ways that we can follow 4 (easy) in our daily life. Firstly, turn 5 lights if they are unnecessary. Then, go out in environment-friendly ways such as by bus, by subway or by bike. We can even walk to work when possible. It is really good for our health 6 helps us save some money. Thirdly, try our best to 7 (use) things like books, paper, magazines and so on. And we can also take a cloth bag when we go 8 (shop). Please don’t use plastic ones. Of course the public should realize it is 9 (everyone) duty to protect the environment. At 10 same time, the government should make laws to guide people’s behavior. We only have one earth. Let’s hold up a green umbrella together for the earth mother. 【答案】1.have done 2．importance 3．to introduce 4．easily 5．off 6．and 7．reuse 8．shopping 9． everyone’s 10．the 【导语】本文主要介绍了保护环境的重要性，并提出了一些日常生活中简单实用的环保建议，呼吁大家共同行动。 【详解】1．句意：在过去的几年里，人们为了快速发展经济以环境为代价做了很多事情。根据“in the past few years”可知，句子时态是现在完成时，其构成是“have/has done”，主语People是复数，助动词用have，do的过去分词为done，所以填have done。 2．句意：我确实认为，现在是我们了解保护环境的重要性并采取行动的时候了。根据“the...of”结构可知，空处应填名词，important的名词形式是importance，意为“重要性”。 3．句意：今天，我想介绍一些简单但有用的方法，我们可以在日常生活中轻松遵循。would like to do sth.意为“想要做某事”，是固定搭配，因此此处用不定式形式to introduce。 4．句意：今天，我想介绍一些简单但有用的方法，我们可以在日常生活中轻松遵循。空处修饰动词follow，需用副词形式，easy的副词是easily，意为“容易地”。 5．句意：首先，关掉不必要的灯。根据“...lights if it is unnecessary”可知，此处指“关灯”，turn off意为“关掉”，是固定短语。 6．句意：这对我们的健康真的有益并且帮助我们省些钱。前后两部分是并列关系，表示同时具备的好处，应用并列连词and连接。 7．句意：第三，尽量重复利用如书籍、纸张、杂志等物品。根据环保主题语境，此处指“重复使用”，use加上前缀re-构成reuse，符合语境，不定式符号to后跟动词原形。 8．句意：当我们去购物的时候，我们也可以带一个布袋。go shopping意为“去购物”，是固定搭配，shop需变为shopping。 9．句意：当然公众应该意识到保护环境是每个人的责任。空后是名词duty，此处需用everyone的所有格形式everyone’s，表示“每个人的”。 10．句意：同时，政府应该制定法律来指导人们的行为。at the same time意为“同时”，是固定短语，此处需填定冠词the。 九、选词填空 阅读短文，从方框中选择适当的词并用其正确形式填空，使短文通顺、意思完整。每空限填一词，每词限用一次。 pollute, recycle, protect, sustainable, responsible, reduce, harm, develop, build, policy Nowadays, environmental problems are becoming more serious.

The earth is the only home for everyone on it. It’s crying for our help now. As middle school students, we have the power to make a difference and help save the earth! To protect the earth, we can start by saving water, planting more trees, and reducing pollution. We can also save animals and recycle whenever possible.
