关键词:肯定句句末否定句

Ⅰ. also较正式,位置通常靠近动词,用于句中;且用于肯定句中。如:

① He also plays football. 他也踢足球。

② I was also there. 我也在那儿。

Ⅱ. too 多用于口语,通常置于句末,前边须用逗号隔开,也可用于句中,且前后均须用逗号隔开,用于肯定句中。如:

① He is a worker, too. 他也是名工人。

② The two cows, too, are white. 那两头奶牛也全都是白的。

Ⅲ. as well 是副词短语,多用于口语,只用于句末。如:

① She not only taught us English but taught us maths as well.

她不但教过我们英语, 还教过我们数学。

② He is a teacher and a writer as well.

他是位教师,也是一位作家。

Ⅳ. either 用于否定句中,常置于句末。在肯定句变否定句时,其中的also, too, as well都要改为either。

① Yesterday I didnt watch TV and I didnt see the film, either.

昨天我没有看电视,也没有看电影。

for/from/since

Ⅰ. 三者都能用来表示时间,但用法不同。

since “自从”,所表示的是一个时间点。可用作介词,也可用作连词,后接时间名词或短语,或引导时间状语从句;要求前面的谓语动词或主句的谓语动词必须用完成时态,要用延续性动词。而since引导的从句中的谓语动词通常应是短暂性的动词。若接时间,则应为点时间。如:

① He has worked there since1989.

② She has lived here since she moved here.

Ⅱ. from “自从” 只用作介词,表一个事情的开始点,可用于过去、现在或将来的时态。如:

① They worked from 7:00 to 12:00 this morning.

② We have been good friends from childhood.

Ⅲ. for 作为介词,后面接段时间,用于完成时、现在时、过去时和将来时,句中要用延续性动词。如:

① Well stay here for ten minutes. 我们将在这儿呆10分钟。

② They have studied English for three yeas. 他们已经学习英语三年。
