请帮忙看一下这两句话写的有语法错误么?
(1)The youngest child of the family was only a survivor of the earthquake,the rest of family were died.
(2)In American crime made people unfit to live in some streets.
(3)The several cars have crash into each other on the highway due to the fog.
另外请问due to 只能用以引导形容词短语,这里在修饰谁?

第一句把”was only a surivor of the earthquake "改成“was the only surivor in the earthquake"
第二句没有语法错误,但感觉用词怪怪的
第三句把开头的the 去掉
due to(由于,因为).按照传统语法due to主要引导表语,如:
His absence was due to the storm.他因暴风雨而缺席.
Her success was due to her hard work.她成功是因为她努力工作.
