麻烦看下这几句语法有没错?

3.People respond to the call of the government ,by offering donations of money and materials,in order to support the diseaster area.
4.When the individuals who are respected by others do some charitable behaviors,other people will follow suit.
有错的麻烦纠正下~或者照着那个意思换个英语句子

答案

1. 语法上没错误
2. 这里 example 最好换成 model（模范）更适合点
3. 措辞上最好改改, by donating money and materials. offer 是很一般的“提供”的意思,用在这里不太好,而 donate 本来也有“捐献”的意思,也是提供,所以你这样说就有点重复啰嗦了.
4. suit用在这里有点莫名其妙, 你就说 follow them 行吗?
