英语语法问题,我认为有两个谓语了,请帮我分析下
Long before children are able to speak or understand a language,they communicate through facile expressions and by making noises.
答
本句含有时间状语从句，before引导时间状语从句，所以不存在两个谓语的情况。
答
看逗号之前的那个句子，是 long before 引导的时间状语从句，后面才是主句。
答
谓语只有一个communicate ,Long before 引导的是条件状语从句,那么Long before 后面的句子是状语成分,不是主句,主句是逗号后面的句子,所以只看主句,这样说你明白吗
