【现在进行时】

1.(2010北京) -- I’m not finished with my dinner yet.
-- But our friends _______ for us.
A. will wait B. wait C. have waited D. are waiting
答案：D
解析：“我还没有吃晚饭呢。”“可是朋友们在等我们”。本题考查动词的时态。根据语境“这个在等我们”可以判断此处为正在进行时，故选D。

2.(2010陕西) It is reported that many a new house _______ at present in the disaster area.
A. are being built B. were being built C. was being built D. is being built
答案：D
解析：“据报道，目前在这个受灾地区正在建很多新房子”，本题考查的是主谓一致和时态。many a：a large number of许多。many a + 单数名词 + 单数动词。如：Many a strong man has weakened before such a challenge.很多坚强的人面对这种挑战都动摇了。Many a famous pop star has been ruined by drugs.很多流行的音乐歌星都因毒品而被毁了。根据谓语动词应该用单数，故排除AB两项。根据at present，时态应该是现在时态，所以D选项是正确的。

3.(2008重庆) Teenagers __________ their health because they play computer games too much.
A. have damaged B. are damaging C. damaged D. will damage
答案：B
解析：因为年轻人玩电子游戏玩得太多，所以他们正在损害自己的健康。

4.(2008辽宁) — Have you got any job offers?
— No. I __________.
A. waited B. had been waiting C. have waited D. am waiting
答案：D
解析：依上文可见，甲在询问乙是否有人提供给乙工作，而乙回答说还没有，还在等待，显然在说现在的状况，现在一直在等。进行时有两种常见的用法：①正在进行的动作；②近一段时间一直持续的动作。该处考察的是进行时态的第二种用法。

【过去进行时】

1. (2010课标全国I) -- Have you finished reading Jane Eyre?
-- No, I _______ my homework all day yesterday.
A. was doing B. would do C. had done D. do
答案：D
解析：“你读完《简爱》了吗？”“没有，我昨天一整天都在写作业”。本题考查动词的时态。从all day yesterday可知，昨天一整天都在写作业，用过去进行时表示过去某段时间一直在进行的动作。一般过去时与过去进行时的区别：一般过去时表示过去完整的、已经结束的动作，如果表示过去某个时间或某段时间正在做或一直在做的某事则用过去进行时。

2.(2010湖南) I walked slowly through the market, where people _______ all kinds of fruits and vegetables. I studied the prices carefully and bought what I needed.
A. sell B. were selling C. had sold D. have sold
答案：B
解析：“我慢慢地穿过市场。在市场里，人们正在出售各种水果和蔬菜。我仔细研究了价格之后购买了我所需要的东西”。本题考查动词的时态。根据句意可知说话者谈论的是过去的事情，故排除AD两项；sell的动作并未发生在walk之前，故不表示“过去的过去”，排除C项；“进行体”具有“未完性，暂时性”的特点，故B项为答案。

3.(2008四川) The telephone __________, but by the time I got indoors, it stopped.
A. had rung B. was ringing C. rings D. has rung
答案：B
解析：本句后半句用的是一般过去时，由此可排除C、D两项；根据句意可知，在说话人去接听之前，电话一直在响，因此用过去进行时。如果选择A项，表示电话已经响过，与后半句不符合。

4.(2007全国II) — Is this anything wrong, Bob? You look sad.
— Oh, nothing much. In fact, I __________ of my friends back home.
A. have just thought B. was just thinking C. would just think D. will just be thinking
答案：B
解析：过去进行时表示过去某时的状态或从过去某个时候开始一直延续到现在的动作。根据时间状语in the past years可确定用现在完成时。又因为substances是discover的被执行者，所以要用被动语态，表示“近几年来，越来越多的物质被发现”。

5.(2007北京) — It was really very kind of you to give me a lift home.
— Oh, don’t mention it. I __________ past your house anyway.
A. was coming B. will come C. had come D. have come
答案：A
解析：根据提供的情景可判断出动作发生在过去，而“路过对方的家”表示过去正在发生的事，所以要用过去进行时。

6.(2007福建) — I saw Jane and her boyfriend in the park at eight yesterday evening.
— Impossible. She __________ TV with me in my home then.
A. watched B. had watched C. would watch D. was watching
答案：D
解析：过去进行时常常表示过去某一时刻或过去某一阶段内正在进行的动作。根据所提供的情景可判断出所指的是昨天晚上8点正在发生的事，所以要用过去进行时。

【将来进行时】

1.(2010福建) -- Guess what, we’ve got our visas for a short-term visit to the UK this summer.
-- How nice! You _______ a different culture then.
A. will be experiencing B. have experienced C. have been experiencing D. will have experienced
答案：A
解析：“你猜怎么着，我们获得了今年夏天去英国进行短期访问的签证。”“太棒了！到时候，你将会体验到不同的文化”。本题考查动词时态。由this summer可知此处应该用将来时，而then表示将来的某个时间，故用将来进行时。

2.(2010浙江) If you plant watermelon seeds in the spring, you _______ fresh watermelon in the fall.
A. eat B. would eat C. have eaten D. will be eating
答案：D
解析：“如果在春天种下西瓜种子，秋天你就会吃到新鲜的西瓜”。本题考查动词的时态。A项为一般现在时态；B项为过去将来时态；C项为现在完成时态；D项为将来进行时态，表示将来某时间正在进行或某时间段内一直在进行的动作，in the fall为表示将来的时间状语，故选D。

3.(2009安徽) Daniel’s family __________ their holiday in Huangshan this time next week.
A. are enjoying B. are to enjoy C. will enjoy D. will be enjoying
答案：D
解析：句意“丹尼尔一家人下个星期的这个时候正在黄山度假”。根据this time next week判断，选用将来进行时will be doing。
