He says that he feels cold和 He says he feels cold有什么差别,有that和没that有什么区别吗? He said that he will go abroad next year.可以说He says that he will go abroad next year吗? It isnot what he (tells/says)that make people laugh. She says that he want an apple有错吗?还有, A wise man thinks all that he says, a fool says all that he thinks!隐意是?帮忙翻译下 he says是什么意思
