students 学生,是可数的,所以用manyThere is _much more__ space in our school than in theirs.space 空间,不可数,就可用much,are 也改成isThere is _much more__ fun in our school than in theirs.fun 乐趣,不可...many more 是指数量“更多“ 而不只是多more

There are _more__ students in our school than in theirs. 这里more比较级显示的是多，但数量上要显示更多呢？只能用 many more.

我校的学生比他们多；我校的学生比他们更多 。这两句翻译过来然道都是 Our school has more students than theirs....????? 你怎么在句子里显示数量上更多的差别呢？那只能在more比较级前再强调，用many more来区分。
