Module7 UNIT2 It's big and round.教案(一)(7)
The things are getting worse.情况是越来越糟了。
3. 所有半系动词的被动语态要分情况讨论。
英语中某动词在作系动词用时,无被动语态,而作实义动词用时,才有被动语态,二者不可混为一谈。例如:
不能说:
The apple is tasted good.
(因为taste此时是系动词,“尝起来”之意,指的是苹果的性质,无被动语态)
但我们可以说:
The apple is tasted by me.这苹果被我尝了一下。
(taste此时指“尝一尝”这一动作,有被动语态)
因此,在平时的英语教学和学习之余,要有意识地注意半系动词在具体的语言环境中到底是系动词用法还是实义动词用法,要注意区分、识别。
4. 瞬间动态系动词能否与时间段连用的问题
英语中某些表示瞬间意义的系动词不能与“for+时间段,since+时间点,how long until+时间,by + 时间,so far”等直接连用。例如:
①不能说:He has become a teacher for 2 years.
应改为:He has been a teacher for 2 years.
②不能说:He has turned writer since 3 years ago.
应改为:He has been a writer since 3 years ago.
或It is three years since he turned writer.
③不能说:He got angry until his child came back home.
应改为:He didn’t get angry until his child came back home.
5. 系动词能接几种表语(从句)
系动词除了接adj.\n.\prep.短语,某些adv.以外,还可接以下几种表语形式:
①能接as if/as though表语从句的系动词有:look(看起来),smell(闻起来),sound(听起来),feel(觉得);appear(显得),seem(似乎)。例如:
It looks as if there are going to have snow.
看样子天要下雪了。
He looked as if he had just stepped out of my book of fairy tales.
他看来好像刚从我的童话故事中走出来似的。
