一、單選題(本大題共15小題,共15.0分)
1. When _______ the two countries, we’ve found they have much in common.
A. compared B. compare C. being compared D. comparing
【答案】D
【解析】
【詳解】考查省略句。句意:比較這兩個國家時,我們發(fā)現(xiàn)它們有許多共同之處。在when, while, if, as if, though(或although), as, until, once, whether, unless, where等連詞連接的狀語從句中,常省略跟主句相同的主語和be動詞。從句完整為When we are comparing the two countries。省略主語與be動詞,故選D。
【點(diǎn)睛】狀語從句中的省略
(1)在when, while, if, as if, though(或although), as, until, once, whether, unless, where等連詞連接的狀語從句中,常省略跟主句相同的主語和be動詞。如:

Errors, if (there are) any, should be corrected. 如果有什么錯誤,就應(yīng)當(dāng)改正。

She studies very hard though (she is) still rather weak. 她盡管體弱,但學(xué)習(xí)仍十分努力。
(2)“when(或if, where, wherever, whenever, as soon as, as fast as, than等)+possible/necessary等”,中間省略了it is(或was)。如:
Answer these questions, if (it is) possible without referring to the book. 如果有可能,請不看書回答這些問題。
