100.._____your budget, keep a careful record of each dollars you spend every day.

A.     Follow           B. To follow         C. Following           D. Followed

【解析】B本题考查非谓语动词。根据句子意思：为了和开支预算相符合，表示目的，要用动词不定式。

99.A beach house caught fire last night, ______seven students living in it.

A.     to kill                          B. killing           C. having killed    D. killed

【解析】A ：不定式和现分均可用作结果状语，不定式偏重于表示出乎意料的结果，特别是前面有only时。如：He lifted a rock only to drop it on his own feet.他搬起石头砸了自己的脚。

    Her father left home, never to be heard from.她爸爸离开了家，从此杳无音信。

98.When the American constitution ______into effect in 1789,it didn’t contain any words guaranteeing the basic rights of ordinary citizens.

A went                          B. had gone         C. has gone       D. was going

【解析】A ：本题前半部分中有明确的时间状语in 1789，表明在过去某个时间发生了某事，并非表示在过去的过去发生了某事，故排除B项；go into effect为结束性动词，不宜用进行时态。B项为现在完成时，不与表过去的时间状语连用。

97. ------Flight 302 to London_______ until 7:30 tomorrow morning.

-----No wonder I hear so many complaints from the passengers.

A.     has been delayed              B. delay           C. delayed         D. will be delayed

【解析】：确定首句时态的关键信息在于----No wonder I hear so many complaints from the passengers.既然听到了乘客的抱怨，说明航班已经被推迟。也就是说，推迟这一动作发生在过去且已对现在产生影响，所以用现在完成时。

96.------What can I do for you?

------I’d like to have the film____. How much is it?

A  developed                  B.washed           C.taken           D.made

【解析】A：本句考查汉语中“洗”在英语中的对应表达：照片的“洗”应为develop=trrat (an exposed film)with chemicals so that the picture can be seen.衣服的“洗”为wash=clean with liquid.

99. ---- I’ll be able to come to see your performance at 8:30 tomorrow evening.

---I’m sorry, by then my performance____ and I___ reporters in the meeting room.

A.     will be ended; will meet            B. is to end; will meet 

 C. will have ended; will be meeting     D. will be ended; am going to meet

【解析】C：本句分两部分，一是与时间状语by then相呼应的句子时态应用将来完成时；二是与at 8:30 tomorrow evening相对应的将来即时时间句子应使用将来进行时。

------No officer. I can’t have been.This car doesn’t do 80.

A.     are driving                B.have driven                C.had driven    D.were driving

【解析】D：本题考查即时时间，即当时我看到你违章时那个时间点。过去进行时表过去某一时刻或某一阶段正在发生的动作。

98.----Fined ￥100!You know you ________100KM an hour,don’t you?

97..I would have gone fishing yesterday,but it ______all day.

A.     had been raining           B.was raining               C.should rain     D.has rained

【解析】B本题考查时态，从but it ______all day.来看，是说昨天一直在下雨，过去正在进行的动作，要用过去进行时态。

96.When she came out, Mary looked a bit tired because she _____the house.

A. cleaned                                      B. was                 

C. had cleaned                                   D.had been cleaning

【解析】D：本题考查动词时态，侧重说明在she came out之前的动作，D项为过去进行时，表示从过去某一时间开始到过去某一时间一直进行的动作。
