现在完成时练习题及答案(老师专用) (1)

现在完成时讲解一．现在完成时结构：

AAA cut put

ABC fly begin write ABB buy lose dream

二．现在完成时的标志

already（已经），yet(只用于否定句和疑问句句尾，用在否定句中翻译成“还没”，用在疑问句中翻译成“已经”),just(刚刚),ever(曾经),never(绝不，从不),before(之前),so far(到目前为止),since(自...以来),for+时间段

1.我已经刷过牙了。

2.我还没吃早饭。

3.我刚刚完成了我的家庭作业。

4.到目前为止我已经学习2000个单词。

5.我之前从没去过北京。

2)since+时间段+ago

2.从五个小时以前他就一直呆在这里。

3)since+从句（从句用过去时）

3.她在这教英语自从她来到这里。②for+时间段

1.）他已经学了五年的英语了。

③对for或since引导的时间状语提问必须用how long,决不能用when.

1).I have lived here for six years.(划线提问)

2).He has been in China since he came.（划线提问）

四．瞬间动词和延续性动词的转化

瞬间动词，也叫终止性动词、点动词、非延续性动词、短暂性动词。这类动词所表示的动作在瞬间就可以完成，不能延续下去，即动作从开始到结束所持续的时间极短。瞬间动词往往表示动作的结果，或表示短暂性、一次性的动作。（arrive,leave,borrow,buy,begin,start,die）

在完成时当中瞬间动词不能和表示一段时间的状语连用（不能和since,for, how long连用）

延续性动词表示能够延续的动作。如：study,work,stand,lie,walk,keep,have, wait,watch,sing,read,sleep,live,stay等等。

那如果非要与表示时间段的时间状语连用怎么办？

把瞬间动词转换成延续性动词。

1.这支钢笔我已经买了五年了。

2.Tom的爷爷已经过世5年了。

3.这场电影已经开始了5分钟。

但在否定句中，短暂性动词可以与时间段连用。

1）我买这辆自行车还不到一年。

五．have been to/have gone to/have been in的问题

①have been to---曾经去过某地，但是现在不在那里了。常和just，ever，never 搭配。

A B说话时人在A点I have been to Beijing.

②have gone to----到某地去了，不在A点，到没到B不知道，可能到了，可能在途中，反正不在A点

A B---Where is your father?-----He has gone to Shanghai.

③have been in----在某地带了一段时间，后面加时间段

B M r.Chen has been in Suzhou for three months.

陈先生在苏州呆了三个月了。

但在否定句中，短暂性动词可以与时间段连用。

1.）我买这辆自行车还不到一年。
