Question

问几个英语问题？

1：a number of/the number of用法？
2：escape from接sb还是sth还是someplace?
3:Think of a dream you had recently是什么意思？had和recently之间有什么关系？
4：定语从句：that，who，which这三个怎么用？

Answer 1

1.a number of 大量的(修饰可数名词)
the number of 某某的数目
例:
There are a number of trees around the house.
房子旁边有很多数
The number of the students in class 1 is 56.
一班的学生人数是56.
2.escape from 从某某地方逃离,所以后面是someplace
3.想了一下你最近做的一个梦.
think of a dream (you had recently)
you had recently这里做后置定语修饰前面的dream.
4.例:
I didn't know that you were here yesterday.
我不知道你昨天在这.
I want to know who studys best in your class.
我想知道你班上谁学习最好.
He didn't tell me which book to choose.
他没告诉我该选哪本书.
定语从句是要靠积累的,不可能一时就可以全部弄懂,
要花功夫的,加油!

Answer 2

a number of很多（修饰可数名词） a number of people
the number of具体数量 the number of the children is 5

escape from后面都可以加sb/sth/sp

recently是最近，表明是过去式
had是表明，你过去有过的梦想
所以合起来是，你最近有过的梦想

that修饰 人、东西 都可以
who修饰 人
which修饰 东西
