(五)重点、难点分析
1. 过去进行时:表示在过去某一时间内正在进行的动作。
构成:was / were + 现在分词(其中was是am、is的过去式,were是are的过去式)eg. 1) I was doing my homework then . 那时,我正在做作业。
2) He was cooking in the kitchen at 12 o'clock yesterday .昨天12点,他正在厨房烧饭。
用法:1)过去进行时表现过去某一时刻正在进行的动作。
eg. She was writing a letter when I came in .我进来时,她正在写封信。
2)过去进行时还表示过去某阶段正在进行的动作。
eg. They were waiting for you yesterday .他们昨天一直在等你。
2. 现在分词的构成
1)一般动词在词尾加-ing,读[iη],如go→going。
2)以不发音字母e结尾的动词,先去掉e,再加-ing。
come→coming make→making write→writing
3)以重读闭音节结尾的动词,如果末尾以一个辅音字母结尾,应先双写这个字母,再加ing,x和w结尾的除外。
如get→getting swim→swimming show→showing
4)以字母y结尾的单词,直接加ing。
如carrying、playing、studying。
5)以字母ie结尾的动词,变ie为y,再加ing。
die→dying lie→lying
6)以元音字母加e结尾,或以e结尾,且e发音的动词,直接加-ing 。
see→seeing be→being
3. 使用进行时态的注意事项
1)一些动词,如see、hear、love、like、know、remember;understand、have等表示感情、知觉和状态的词,一般不用于进行时态。
2)在there和here引起的句子中,常用一般现在时代替现在进行时。
eg. Here comes the bus .
There goes the bell .
4. 过去进行时和一般过去时的区别
1)过去进行时表示过去正在进行的动作,而一般过去时则表示一个完整的动作。如:
They were writing letters to their friends last night .昨晚他们在写信给他们的朋友。(没有说明信是否写完)
