1.Don't dig the field ___ I come home .
A.until B.before应该选哪个呢?为什么?
2.The doctor said;"I am afraid several of your teeth need ___to .
A check B.examining C.seeing
答案是选C的,是不是跟后面的to有关..?

NEED DOING SOMETHING 是固定词组

1. A not until

2.跟to无关,可以理解为need to be

1.B
2.题目完整了吗?need 后面不一定都跟doing ,也可以是need to do.
有这样一句例句:“I am afraid several of your teeth need to be checked.”
