1. When a pencil is partly in a glass of water, it looks as if it ______.
A. breaks B. has broken C. were broken D. had broken
分析：该题考查 as if引导的从句的用法。 as if引导的从句若与事实相悖，则用虚拟形态。因此C为正确答案。
2. Betty ______ a red shirt ______ today.
A. puts; on B. has; on C. dresses; up D. wear;/
分析：短语动词 have on与 wear一样，意思是"穿着"、"戴着"，表示状态，但前者无被动式和进行式；dress用作及物动词时，后面接人作宾语，而不接名词作宾语；本题不选D是因为主语是第三人称单数。故B为正确答案。
weather turned out to be very good, ______was more than we could expect.
A. it B. which C. that D. what
分析：本题考查非限制性定语从句中关系代词的选用，正确答案是B。it和what均不能用来引导定语从句，that不能用来引导非限制性定语从句。注意；该句中的.标点很重要，如果把逗号变成句号，就可用it或that来指代前文。
live in a large house, in front of ______there are many beautiful flowers.
A. that B. which C. it D. this
分析：本题考查定语从句中介词后面的关系代词的选用，很明显，A项不正确，因为that不能用在非限制性定语从句中。英语中，介词后的关系代词只能用which（指物）和whom（指人），因此本题只有B项符合要求。
r living in Paris for 50 years he returned to the small town ______he grew up as a child. .
A. which B. that C. where D. when
分析：本题考查定语从句中关系副词的使用。关系副词 where代替 in the small town，在定语从句中充当地点状语。答案为C。
6. The newly-built bridge __________ the beauty of the city.
A. is added to B. adds up to C. adds to D. adds up
解析：add to，增加；增添。add（the figures）up将（这些数字）累加起来；add up to指数目、数量总计达……；add（sugar/salt）to（the water）往水加些糖／盐。根据题意，答案为C。
7 the way home, he was _______ in a storm. As a result, he developed a cold.
A. met B. caught C. kept D. left
解析：be caught在这里的意思是"陷入困境"或"赶上……"，后面常接介词in，所以答案为B。
