S:学生 T: 老师
S: 老师,时间状语“for+段时间”结构中, for必须加吗?比如:
He worked here three years.
这句话中three years前省略了for?
T: “for+段时间”在肯定句中,for可省。 否定句和置于句首时,不可省。比如:
The meeting lasted (for) two hours.
I haven’t seen her for a long time.
For a whole day, it has been raining.
S: 哦!原来如此!
还有,on that day和that day有什么区别?不是由this,that,these,those构成的时间状语前不用介词吗?
T: on that day 和that day区别如下:
1.词性不同:
前者为介词短语,后者为名词短语。
2.都可做时间状语,区别不大,加介词只起特别强调作用。如:
I met him (on) that day.
3.that day作为名词短语,在句中还可作主宾表成分。如:
That day is unforgettable.
S: 明白了!
那those days 和in those days区别也一样吧?
T: 对。重新总结一下:
一般情况下,时间状语前不用介词的五种情况:
1.today, yesterday, tomorrow 或后加 morning, afternoon, evening 时;
2.this, that, these, those构成的时间短语前;
3. last, next构成的时间短语前;
4. every, each, all, some, any构成的时间短语前;
5. “for+段时间”在肯定句中,for有时可省。
注意:说一般情况,是因为也有例外。
比如:during last Summer
within the next few days
(请细心体会介词存在的意义)
S: 就是说话人特别强调某一时间时,可加上适当的介词,来表达某种情感态度。
T: 理解得很透彻哦!
