注意neither与none的区别:
Neither of the two rooms has been used for more than two months.
这两个房间使用都没有超过两个月。
结构分析:Neither of the two rooms是主语,has been used是被动谓语,现在一般时,for more than two months是时间状语。
I took several kinds of medicine for cough, but none of them had any effect.
我吃了好几种咳嗽药,但都没有效果。
结构分析:I是主语,took是谓语,现在一般时,several kinds of medicine是宾语,for cough是状语, but是连接词,表示转折,none of them是主语,had是谓语,现在一般时,any effect是名词词组,作宾语。
None of the pupils knew the answer.
学生中谁都不知道答案。
结构分析:None of the pupils是主语,knew是谓语,现在一般时,the answer是名词词组,是宾语。
another指三个以上不定数目中的“另一个、类似的一个”。例如:
This route takes us too long. There must be another that is shorter.
