这几个英语句子语法错在哪里?搞不懂
1.Becauseof people are bombarded with various advertisements,so they sometimes find ithard to decide which product to buy.
2.Inmany countries,traditional foods being replaced by international fast foodsnow.
3.Youngchildren are very difficult to cope with so much homework.
4.Some employersfocus on academic qualifications; pay less attention to life experiences andpersonal qualities.

答案

because 和 so 一般不同时出现在在一个句子里,而且because of 后面不能跟句子.
所以把because of 去掉
变成：people are bombarded with various advertisements,so they sometimes find it hard to decide which product to buy.
being前面要加are,be being done 现在进行时的被动语态
变成：In many countries,traditional foods are being replaced by international fast food snow.
逻辑上的错误,主语应该是to cope with so much homework,用it来做形式主语
变成：It's very difficult for young children to cope with so much homework.
pay改为paying,现在分词短语做状语
变成：Some employers focus on academic qualifications,paying less attention to life experiences and personal qualities.
