1.The population of the world ( ) still ( ) now.
A.will；grow B.have；grow C.is；growing D.is；grown
答案：C
翻译：世界人口现在仍然在增长.
分析：now 现在进行时的标志,表示动作正在进行,只有C是现在进行时
2.where do you think ( ) he ( ) the computer?
A./；bought B.has；bought C.did；buy D.does；buy
答案：A
翻译：你认为他是在哪里买的电脑
分析：原句其实可以还原成Do you think where he bought his computer?
think后面的相当于宾语从句,在宾语从句中是用陈述语气的,陈述语气就是主语+谓语+宾语的语序.where是特殊疑问词,应该放到前面去,因此整个句子变为Where do you think he bought his computer?
前面已经有助动词do,所以不能再使用has ,did 和does,淘汰其他三项.
3.He has ( ) for three or four days.
A.got a headache B.fallen ill
C.caught a cold D.had a cough
答案：D
翻译：他已经咳嗽三四天了
分析：句子中for引导一段时间,表示动作持续了一段时间,因此必须使用延续性动作,get fall catch 都是短暂性动作,只有have是延续性的.
4.What is the weather like this summer here?
—There ( ) very little rain.
A.has B.has been C.are D.have been
答案：B
翻译：这里今年夏天的天气怎么样,几乎没有下雨
分析：这里是there be 句型,there be句型单复数由后面的主语决定,rain是不可数名词,因此使用单数,淘汰CD,there be 句型不能是there have的形式,选项B是there be句型的现在完成时,这里的have不是实义动词有的意思,而是构成完成时态的助动词
5.This morning I had hardly got to my school when it ( ) to rain.
A.had begun B.was beginning C.began D.begins
答案：C
翻译：我刚一到学校就下起了雨
分析：这里有个固定句型 hardly...when ,意思是“一...就...”表示一件事紧接着另一件事发生,when从句里事情晚于主句事情的发生,因此前面部分一般用过去完成时,后面部分用一般过去时.
6.The last time I ( ) to the cinema was two years ago.
A.go B.have gone C.have been D.went
答案：D
翻译：上次我去看电影还是两年前.
分析：句子中有明确的过去时的标志时间 two years ago,因此使用一般过去时.
7.How did the accident happen?
—You know,it ( ) difficult to see the road clearly because it ( ).
A.was；was raining B.is；has rained
C.is；is raining D.will be；will rain
答案：A
翻译：意外是怎么发生的?你知道的,因为当时正在下雨,所以很看清道路.
分析：这句话是对过去正在进行的动作的描述,因此使用过去进行时
8.I ( ) my clothes,and the phone rang.
A.wash B.washed C.am washing D.was washing
答案：D
翻译：我正在洗衣服的时候,电话响了
分析：这句话表达的意思是电话铃响起来我正在进行的动作.
9.David promised to come round to have supper with us today.
—But he ( ) .I have been alone for half an hour.
A.will not B.had not C.has not D.does not
答案：A
翻译：David答应过今天来和我们一起吃晚饭,但是他不会来了,我已经一个人在这半个小时了
分析：根据翻译可知,不会来应该是用将来时.会不会来时将来才会发生的事情 而不是过去和现在 所以淘汰其他三项
10.The Harry Potter books ( ) pretty popular since they were published.
A.become B.will become C.have become D.are becoming
答案：C
