参考答案:
一、单项选择。
14
成都少年时教育
劝君莫惜金缕衣 劝君惜取少年
时
1、现在完成时主要强调过去发生的动作对现在造成的影<
br>响,或过去发生的动作还未结束,一直持续到现在或将
来,重点在于对现在的影响。这种考查难度
较大,往往
无时间状语,需要从上下文分析、推理才行。故上两侧
根据上下文分析、推理,正确
答案是B。
2、现在完成时常与already(已经),just(刚刚,正好),
ev
er(曾经),never(从来,也不;从不),before(以
前),yet(仍然)等连用。故
2应选B。
3、C
4、现在完成时常与recently(近来),so
far(到目前
为止),in the past“last + 一段时间”等时间状语连
用。因为上述短语表示的是从现在起往前推算的一段时
间,句中的动作是从过去某一时间或时刻开始持
续到现
在的。故4应选D。
5、C
6、现在完成时时常与“for
+时间段或since +过去时间点”
连用(含从句,从句过去时)。故6应选C。
7、C
8、现在完成时还与once(一次),twice(两次),three
times(三次),several
times(几次)等表示重复次数
的词语连用。故8应选B。
15
成都少年时教育
劝君莫惜金缕衣 劝君惜取少年
时
9、现在完成时与一般过去时容易混淆,就是因为它们所<
br>表示的动作都发生在过去,但二者又有区别:一般过去
时表示过去某个时间发生的事、存在的状态
或经常发生
的动作,说话的侧重点在于陈述一件过去的事情,与现
在没有关系;现在完成时表示
与现在有关系的发生在过
去的动作,它不与表示过去的时间状语(如yesterday ,
last week , a moment ago等)连用。故9的正确答
案为B。
10、B
11、现在完成时中,非延续性动词不能与for和since引
导的表
示一段时间的状语连用,通常是用相应的延续性
动词来代替。故11的正确答案依次为:D。
12、B 13、A 14、C 15、A。
16、“havehas gone to +
地点”表示“某人去了某地
(还未回来)”,指主语所指的人不在这儿。“havehas
been in +
地点”表示“在某地呆了多长时间”,常与表
示时间的状语连用。“havehas been
to +地点”表示
“曾经去过某地(但现在已不在那儿)。”故16的正确答
案为A。
17、A 18、D 19、C 20、C
