21. John plays basketball well, ________ his favorite sport is badminton. (2009北京卷)

A. so                      B. or                       C. yet                     D. for

【答案】C。

【考点】考查连词的用法。

【解析】yet在此表转折，与but的意思比较接近。句意为：约翰篮球打得好，但他最喜欢的运动是羽毛球。又如：He worked hard, yet he failed. 他工作努力，可是他失败了。

22. You may use the room as you like ________ you clean it up afterwards. (2009北京卷)

A. so far as           B. so long as        C. in case              D. even if

【答案】B。

【考点】考查连词的用法。

【解析】根据句意，只有B最符合语境。比较四个选项的意思：so far as主要用于表示范围或程度，如：So far as I know, that is highly unlikely. 就我所知，那是极不可能的。so long as表示条件，意为“只要”，如：You can take my car so long as you drive carefully. 你可以用我的汽车，只要你小心点儿开。in case可以表示条件或目的，其意为“如果”“以防”，如：In case I forget, please remind me about it. 万一我忘记，请请醒我一下。I bought the car at once in case he changed his mind. 我马上买下了那辆汽车，以免他变卦。even if表示让步，意为“即使”，如：You must go tomorrow even if you aren’t ready. 哪怕你没有准备好，明天你也得走。

23. Scientists have many theories about how the universe ________ into being. (2009北京卷)

A. came                B. was coming     C. had come         D. would come

【答案】A。

【考点】考查动词时态的用法。

【解析】根据常识可知，宇宙的形成是发生在过去，故用一般过去时。句意为：关于宇宙如何形成科学家们有很多推测。又如：When did the world come into being? 世界是何时开始存在的?

24. For breakfast he only drinks juice from fresh fruit ________ on his own farm. (2009北京卷)

A. grown               B. being grown    C. to be grown      D. to grow

【答案】A。

【考点】考查非谓语动词的用法。

【解析】由于名词fresh fruit与动词grow之间为被动关系，所以首先可排除选项D。而B和C虽然可以表示被动，但与句意不吻合，因为being grown表示一个正在进行的被动动作，to be grown表示一个尚未发生的被动动作，均不合题意。

25. One of the few things you ________ say about English people with certainty is that they talk a lot about the weather. (2009北京卷)

A. need                 B. must                  C. should              D. can

【答案】D。

【考点】考查情态动词的用法。

【解析】此题可用排除法做，分别将四个选项代入句中，只有can使句意最通顺。全句意为：关于英国人，你能够很确信地说的为数很少的事之一就是他们聊得较多的是天气。答案D。

26. ―What do you think of teaching, Bob?

―I find it fun and challenging. It is a job ________ you are doing something serious but interesting. (2009北京卷)

A. where               B. which                C. when                D. that

【答案】A。

【考点】考查定语从句的用法。

【解析】由于定语从句you are doing something serious but interesting是一个结构完整的句子，不缺主语或宾语，所以不能选关系代词which或that，故可排除B和D；而关系副词when只用于修饰表示时间的名词，故也可排除；where在此相当于in which，引导定语从句，并在定语从句中用作地点状语。又如：I don’t want a job where I’m chained to a desk for eight hours a day. 我不想要一份一天8小时都得守在办公桌前的工作。

27. The way the guests ________ in the hotel influenced their evaluation of the service. (2009北京卷)

A. treated              B. were treated     C. would treat       D. would be treated

【答案】B。

【考点】考查动词的时态与语法。

【解析】因“客人”与“对待”之间为被动关系，故可排除表主动关系的A和C；再根据句意，“影响”已成为事实，而不是“将要影响”，所以这家宾馆对待客人的方式也应是事实，而不是“将如何对待客人”，故选B不选D。

28. All of them try to use the power of the workstation ________ information in a more effective way. (2009北京卷)

A. presenting       B. presented         C. being presented D. to present

【答案】D(http://ask.yygrammar.com/)。

【考点】考查非谓语动词的用法。

【解析】具体说来，本题考查use sth to do sth结构，意为“用……做某事”，其中的不定式为宾语补足语。句意为：他们都试图用工作站的力量来更有效地展示信息。又如：People use a knife to cut things. 人们用刀切东西。The boy used the box to keep his toys in. 这男孩用这个箱子装他的玩具。

30. When I talked with my grandma on the phone, she sounded weak, but by the time we ________ up, her voice had been full of life. (2009北京卷)

A. were hanging B. had hung         C. hung                 D. would hang

【答案】C。

【考点】考查动词时态的用法。

【解析】C。从意思上说，当我在电话里和奶奶聊天时，她的声音听起来很虚弱；但到我们要挂电话时，她的声音又充满朝气。从逻辑上说，应该是“奶奶的声音又充满朝气”在先，“我们挂断电话”在后，如果是反过来的话，那说话者就无法知道“奶奶的声音又充满朝气”这回事了。所以“挂断电话”应用一般过去时。另外，由于by the time后接的定语从句通常要用一般现在时代替一般将来时，用一般过去时代替过去将来时，所以选项D不能选。

31. At first he hated the new job but decided to give himself a few months to see ________ it got any better. (2009北京卷)

A. when                B. how                   C. why                   D. if

【答案】D。

【考点】考查宾语从句的用法。

【解析】分别将四个选项代入空格处，可根据句意排除A、B、C。if在此引导宾语从句，意为“是否”。句意为：开始他很讨厌这份新的工作，但他还是决定给自己几个月时间看是否有所好转。又如：Every now and again she went upstairs to see if he was still asleep. 她时而到楼上看看他是否还在睡着。

32. John was given the same suitcase his father and grandfather ________ with them to school. (2009北京卷)

A. took                  B. had taken         C. were taking      D. would take

【答案】B。

【考点】考查动词时态的用法。

【解析】B。根据句意，约翰的爸爸和爷爷用这个皮箱是发生在约翰得到这个皮箱之前，所以空格处应填过去完成时。句意为：约翰的爸爸和爷爷以前上学用的皮箱现在被拿给约翰用了。

33. The biggest whale is ________ blue whale, which grows to be about 29 meters long―the height of ________ 9-story building. (2009北京卷)

A. the; the            B. a; a                    C. a; the                 D. the; a

【答案】D。

【考点】考查冠词的用法。

【解析】第一空填定冠词，表示类别；第二空填不定冠词，表示泛指，a 9-story building意为“一座9层高的楼房”。

34. ________ twice, the postman refused to deliver our letters unless we chained our dog. (2009北京卷)

A. Being bitten    B. Bitten                C. Having bitten   D. To be bitten

【答案】B。

【考点】考查非谓语动词的用法。

【解析】根据句意，句子主语the postman与动词bite之间为被动关系，所以首先可排除选项C；再根据句意（尤其是注意关键词twice）可知，表示正在进行选项A和表示将要发生的选项D均不合题意。全句意为：邮递员被狗咬了两次之后要我们把狗拴起来，不然就不给我们送信了。

35. Being a parent is not always easy, and being the parent of a child with special needs often carries with ________ extra stress. (2009北京卷)

A. it                        B. them                  C. one                    D. him

【答案】A(http://www.yygrammar.com/)。

【考点】考查代词的用法。

【解析】it 用于代替前面的being the parent of a child with special needs（做一个有特殊需求的孩子的父母）。carries with it extra stress的正常结构是carries extra stress with it。句意为：为人父母并非总是一件容易的事，作为一个有特殊需求的孩子的父母，会有更多的额外的压力。
