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：該題考查 as if引導(dǎo)的從句的用法。 as if引導(dǎo)的從句若與事實(shí)相悖，則用虛擬形態(tài)。因此C為正確答案。

　　2. Betty ______ a red shirt ______ today.

　　A. puts; on B. has; on C. dresses; up D. wear;/

　　分析：短語(yǔ)動(dòng)詞 have on與 wear一樣，意思是"穿著"、"戴著"，表示狀態(tài)，但前者無(wú)被動(dòng)式和進(jìn)行式；dress用作及物動(dòng)詞時(shí)，后面接人作賓語(yǔ)，而不接名詞作賓語(yǔ)；本題不選D是因?yàn)橹髡Z(yǔ)是第三人稱單數(shù)。故B為正確答案。

　　3.The weather turned out to be very good, ______was more than we could expect.

　　A. it B. which C. that D. what

　　分析：本題考查非限制性定語(yǔ)從句中關(guān)系代詞的選用，正確答案是B。it和what均不能用來(lái)引導(dǎo)定語(yǔ)從句，that不能用來(lái)引導(dǎo)非限制性定語(yǔ)從句。注意；該句中的標(biāo)點(diǎn)很重要，如果把逗號(hào)變成句號(hào)，就可用it或that來(lái)指代前文。

　　4.They live in a large house, in front of ______there are many beautiful flowers.

　　A. that B. which C. it D. this

　　分析：本題考查定語(yǔ)從句中介詞后面的關(guān)系代詞的選用，很明顯，A項(xiàng)不正確，因?yàn)閠hat不能用在非限制性定語(yǔ)從句中。英語(yǔ)中，介詞后的關(guān)系代詞只能用which（指物）和whom（指人），因此本題只有B項(xiàng)符合要求。

　　5.After 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：本題考查定語(yǔ)從句中關(guān)系副詞的使用。關(guān)系副詞 where代替 in the small town，在定語(yǔ)從句中充當(dāng)?shù)攸c(diǎn)狀語(yǔ)。答案為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將（這些數(shù)字）累加起來(lái)；add up to指數(shù)目、數(shù)量總計(jì)達(dá)……；add（sugar/salt）to（the water）往水加些糖／鹽。根據(jù)題意，答案為C。

　　7 .On 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在這里的意思是"陷入困境"或"趕上……"，后面常接介詞in，所以答案為B。
