例1 When I was at college
I ______ three foreign languages, but
I ______ all except a few words of each.
A. spoke; had forgotten
B .spoke; have forgotten
C. had spoken; had forgotten
D. had spoken; have forgotten
解析:“When I was at college”表示具体的过去时间,所以第一个空格处应用一般过去时。but部分强调与现在有关的行为。正确答案为B项。
例2. ______I haven't heard from him yet.
A. Before long B. By then C. So far D.
So long .
解析:so far意为“到现在为止”,谓语动词用现在完成时;before
long意为“不久”,常与过去时或将来时连用; by then,意为“到那时为止”,如果表示过去,用过去完成叶,若表示将来,则与将来完成时连用。正确答案为C项。
例3. What he said ______ us much to think
about.
A. let B. made C. kept D. left
解析:let和make后接不带to的不定式,即let / make sb.
do sth; keep后接doing, 即keep sb./ sth. doing
sth. leave sb. sth.表示“给某人留下,……”。正确答案为D项。
例4. I heard the news ______on the radio
last night.
A. broadcasted B .broadcasting
C. broadcasts D. broadcast
解析:在“hear +复合宾语”结构中,宾语与宾补之间构成逻辑上的动宾关系,故选用过去分词形式。broadcast的过去式,过去分词与原形相同。正确答案为D项。
例5. Were you successful _____ the experiment?
A. to B. in C. on D. at
解析:表示“在……方面成功”用be successful in (going)
sth. 正确答案为B项。
例6.The police found that the house ______and
a lot of things ______.
A. has broken into; has been stolen
B. had broken into; has been stolen
C. has been broken into; stolen
D. had been broken into; stolen
解析:因为主句有谓语动词是一般过去时,根据宾语从句与主句的时态的对应关系,宾语从句要用过去时的某种时态,所以A、C不能作为选择答案。又因为宾语从句的主语是the
house,所以要用被动语态。故本题的最佳答案为D项。
例7.The room is so dirty. I have to _______
at home for hours to do some cleaning,
or everything will ______as it is now.
A. stay; be remained B. remain; be
remained
C. stay; be stayed D. remain; remain
解析:remain常用作连系动词,后接名词、形容词、分词等。remain没有被动语态。remain
也可作“停留”的意思,与stay同义。本题最佳答案为D项。
