and thus 的用法 最好有例句 有语法分析
Some proper measures must be taken to limit the quantity of alien tourists,and thus protects local environment and history from negative effects of international tourism.
这句话有没有语法错误 尤其是and thus 后应是单数还是复数

Answer 1

and 和thus 能连用的嗦?!
两个都是连词.
,不能连接两个主句,所以要把其中一个变成从句.可以加and 或者thus,前者表示并列关系,不分先后.（以后要看对不对只需把前后内容换一下看句子通不通即可）而thus 是所以.有因果关系的.Some proper measures must be taken to limit the quantity of alien tourists,and protect local environment and historical buildings from negative effects of international tourism.
and后的从句要完整,有主语,这样单复数就根据主语定.这句and后面是短语,要跟前面的动词保持一样.这个很重要哦...平行结构.
