这是初三英语书上的一句话after that,knowledge and ideas spread quickly.请问为什么不是are spread quickly呢?为什么不用被动语态呢?因为书上我找了一下在问题部分他有这样一句句子how are ideas spread today?到底spread 要不要变成被动语态?books are a wonderful invention,and they are also much cheaper/cheaply than computers.请问是填哪一个,为什么?还有much more怎么回事?万分感谢回答者,plz help me!

Answer 1

1 after that,knowledge and ideas spread quickly.
此句中,spread 是不及物动词,如：The word spread fast. 消息散布得很快.
2 how are ideas spread today?
这里的spread 是及物动词,表示人为的散布思想,而spread 的过去分词就是自己,所以无需变形.
如：the pictures are spread before us.
3 books are a wonderful invention,and they are also much cheaper/cheaply than computers.
选much cheaper
much 这里是副词,修饰形容词比较级是一种固定搭配,翻为 “便宜得多”；而在多音节形容词里,它本身的比较级要加more ,所以就变成much more 了,如 they are much more expensive than books. “昂贵得多”
