1．The reason he is late is there was a breakdown on the railway．
A．why; that B．because; that C．that; because D．why; why

全面分析：经过分析句子结构，可知这个句子中包含一个定语从句和一个表语从句。关系词在定语从句中作原因状语，故用why。引导词在表语从句中不作任何成分，且没有实际意义，故用that。

2．_______, nobody was injured in the accident．
A．As it may seem strange B．Because it may seem strange
C．Strange as it may seem D．Strange as may it seem

全面分析：这题考查as用于倒装句表示让步的用法，句型是：形容词/名词/副词/动词+as/though+主语+谓语…，这句话提前的是形容词，句意是，虽然看起来有些奇怪，但在事故中没有人受伤。
3．—How do you think I should receive the reporter?
—______ you feel about him, try to be polite.
A．How B．What C．Whatever D．However

全面分析：根据语境可知不管你觉得他怎样，尽量礼貌地对他。however引导让步状语从句，在从句中作feel的表语。
4．While watching television, ____.
A．the doorbell rang
B．we heard the doorbell ring
C．there was someone knocking at the door
D．the doorbell was ringing

全面分析：这题考查状语从句的省略式，由前面的While watching television可知省略了sb was，所以几个选项中，选主语是人的就可以了，所以B正确，句意是：当看电视时，我们听到门铃响了。选B。
5．Was it through Li Ning, ________working at a high school, ________you got to know Wangke?
A．who I think it was; who B．that I think were; which
C．who I think was; that D．I think who was; which

全面分析：第一空考查定语从句：修饰Li Ning，I think是插入语，所以填who I think was，who在定语从句中做主语，第二空填that是个强调句。句意是：你是通过在一所高中工作的李宁认识王珂的吗？选C。
6．When somewhat better ________ academically, he returned home to continue his research.
A．equipped B．had equipped C．provided D．providing

全面分析：考查非谓语动词。句意：当他在学术上被装备的好一些的时候，他回到祖国继续他的研究。他与装备之间是被动关系，故用过去分词equipped，provided提供，这在不合题意，所以选A。
7．Mark Zuckerberg is the founder of the site Facebook, ______ you can have a
look at each other's pictures.
A．where B．which C．when D．as

全面分析：这题考查定语从句的用法，where引导定语从句修饰Facebook，而且where在定语从句中做地点状语，句意是：Mark Zuckerberg 是Facebook的创始人，在facebook你可以看见彼此的照片。选A。
8．Not having worked out the program, ________ leave the office.
A．so he was forbidden to B．and he didn;t want to
C．his little son couldn;t make him D．he couldn't free himself to

全面分析：这题考查句子结构分析，Not having worked out the program,是现在分词做状语，后面只能是主句，排除AB，又因为Not having worked out the program,的逻辑主语是he，所以选D。
9．____ interested in English may join this club.
A．Whoever B．All who C．Anyone D．Who

全面分析：这题考查anyone的用法，因为interested是形容词作定语，这里只能选代词，如果是A，应该是whoever are，B项也是，选C。
10．It wasn't until then _______ their marriage was breaking up because they had little in common.
A．did I realize B．that I realized

14．The house caught fire last week, with little of the original building _________.
A．remain B．remained C．remains D．remaining

全面分析：句意是：上星期这个房子着火了，原来的建筑几乎没有留下。因为remain是不及物动词，所以用现在分词做宾语补足语。故选D。

A．apology B．change C．difference D．appearance

全面分析：make apology"道歉”；make a change “进行变更”；make a difference“有影响"；make an appearance“出现”。句意：昨天的面试会，他压根儿没露面。他出什么事了？

19．Not until the end of the performance ________ the chance to take photos with the respectable actor.

全面分析：这题考查的with复合结构，with+宾语+宾语补足语，printed就是宾语补足语，因为和修饰的her name是被动关系，句意是：打开书，她发现有一个白色的普通的信封，有她的名字印在上面。选B。

C．Fierce as we are faced with pressure
D．Faced with fierce pressure as we are

全面分析：尽管我们所面临的巨大压力，但是我们需要保持乐观，不管发生什么，都要努力工作以达到目标。as引导的让步状语从句必须倒装。其结构：名词 + as / though + 主语 + 动词 ，位于句首的名词前习惯上不用冠词，即使其前有形容词修饰也不用冠词。故选A。

48．Every year, __________ makes the most beautiful kite will win a prize in the Kite Festival.
A．whoever B．whomever C．no matter who D．no matter whom

全面分析：每年，无论是谁制作出了最漂亮的风筝都可以在风筝节上获奖。分析句子成分，可知这句话缺少主语。A. whoever“无论是谁”，主格形式；B. whomever“无论是谁”，宾格形式；C. no matter who“无论是谁”；D. no matter whom“无论是谁”。这四个词意思都很接近，但是语法功能不同。no matter+疑问词只能引导状语从句，不能引导名词性从句。Whomever是宾格，不能在句中充当主语。综合以上分析，whoever作主语。故选A。

49．Not having a good ________ of English can be a serious barrier to achieving your goals.
A．demand B．appreciatio C．command D．experience

全面分析：这题考查固定词组：having a good command of“精通”，句意是：不能精通英语可能是你取得成功的严重的障碍。选C。
50．One night, at about midnight, I ______ the sky for about an hour. The stars were shining like diamonds.
A．have watched B．had watched C．watch D．watched

全面分析：一天晚上，午夜时分，我看了大约一个小时的天空。星星像钻石一样闪闪发光。根据时间状语one night，可知此句描述的是在过去的时间里发生的事，和现在没有联系，也没有和过去的动作以及时间上的先后对比，所以用一般过去时，故选D。
