一个关于英语的疑问
我在复习时看到这样一道题
----May I go shopping with you mum?
----You'd______
A better not B not better C better not to D not better to
答案是选的A 但我记得结论是 省略不定式时除了be 和have 时,都要保留to
求教老师,这是怎么回事啊,是我记错答案了,还是记错结论了?

Answer 1

这句省略的不是不定式.
完整句型是 you would better not go shopping with me.
would better do sth.
不是would better to do sth.
you are better to do sth.才用不定式.不过这个像你说的那样要省略to do
