would have to 是不是过去时的虚拟呀？

突然想到一个问题,本题比较从句的主语和谓语跟主句都是一样的,那么是否需要省略呢?也就是说没有they do也可以? 还是说如果省略了they do,就不知道到底是they have to know now还是they know now了?

感觉这题e得错误是economical。我觉得they do是可以不补出得。看og129

In an effort to reduce their inventories, Italian vintners have cut prices;their wines have been priced to sell, and they are.
a.have been priced to sell, and they are
b.are priced to sell, and they have
c.are priced to sell, and they do
d. are being priced to sell, and have
e. had been priced to sell and they have

答案是c。c中得do指带的是前面的sell，而不是price to sell

to sunnyspring：

would have done 是过去时态的虚拟语气

但是would have to do绝对是现在时态的虚拟语气

to 流沙：

有没有they do不要紧，问题是have to know的结果还是know.

所以A是know more than (know) now，逻辑不通；而D是would know more than (know) now，符合逻辑
