专题4 现在进行时讲义与练习 (含答案)
一、现在进行时的构成与语义
句型:be doing sth.
语义:表示现在正在进行的动作
be动词:am , is , are
2、 现在进行时的标志性单词:now,listen, look,at the moment
三、 动词的现在分词(又称-ing形式,现在进行式) 的词形变化
1、以不发音的字母e结尾的单词,去掉e再加ing 如: dance — dancing
2、以一个辅音字母结尾的重读闭音节,双写后面的辅音字母,再加ing
如:run — running swim — swimming
3、 除此以外直接+ing,如:do — doing wash — washing
4、 以ie结尾的,变ie为y 再加ing 如:lie--lying
四、现在进行时口诀(背熟)
主语在句首,am are is 跟在后,动词ing形式跟着走,其他成分不可丢。
一般疑问句这样变,把be提到主语前,否定句也很简单,be后再把not来添。
看到now,listen, look 表示动作在进行。
五:不是所有的动作都可以用现在进行时(了解)
有一些表示状态、结果、感觉和感情的动词,如have(有),be(是),like(喜欢),know(知道),want(想要),think(认为),see(看见),hear(听见),forget(忘记)等,一般不用现在进行时。
如:I have a new bike now.现在我有一辆新的自行车。
但不说:I'm having a new bike now.
