4. None of the girls has the answer to the Mathematics problem.
Practice 8
5. The salesman are trying to presuade her to buy the set of knives
salesman后面没有-s,不过,为什么答案是are呢?
或者salesman是special case?
还有,我想请问,can后面的字一定是要original word吗?
因为有一题的题目是:
He has to complete the first chapter before he can do the next.
关于Modul Word,我知道有分present和past,可是我发现有些present的句子却用past的modul word。
modul word是什么情况都适用的吗?
none of 可以加复数名词(none of the children) 或不可数名词 (none of the money)
而 none of + 复数名词 之后,可以使用单数或复数动词:
None of the taxi is 或 None of the taxis are 都正确;
None of the girls has 或 None of the girls have 都正确。
但是,正式文书中应该使用单数的动词如 is, has, does 等等。
