Question

几道英语问题请问下

If you can't do it _ yourself,you can ask others for help.这里用by还是with?为啥?
Mei,take this letter home and give it to your sister.这里的home做什么词?不是to home么?
Some students have gone home.What about the rest?这个the rest 和rests怎么用?
The rest of the food is wasted.这里的is是怎么用的?不是Are么?

Answer 1

1. with...是和...
这里是独立，自己，英语的用法是by oneself
2. take...home把...拿回家，这里的home是副词，不是名词
比如go home不说go to home
3. the rest相当于the rest of the students，不说the rests
4. food是不可数名词the rest of the food仍然是不可数的，因此谓语要用is不用复数
如果主语是复数的，谓语就用are
The rest of the books are (were) sold in two days.
剩下的书两天就卖光了。
