cheer up\cheer on\cheer for.的用法和意义有什么不同..cheer on sth.cheer for sb.这个区别昰正确的么
1.cheer up有两种用法.
1）做及物动词时,意思是“使...高兴/振奋起来”,宾语一般是sb/oneself
如：You should cheer him/yourself up.
2）做不及物动词时,意思是“（自己）高兴/振奋起来”,此时无宾语,不用被动语态
如：Hearing the good news,I cheered up.
2.cheer on只做及物动词,意思是“向...欢呼；为...鼓劲加油”,可以加sb/sth做宾语（但sth比较少用）.
且on是副词,如果宾语是名词,则宾语放在cheer和on中间或放在on后都可以.
如果宾语是代词,则宾语只能放在cheer和on的中间.
如：We all cheered him on.
Why not cheer on his wonderful performance?= Why not cheer his wonderful performance on?
3.cheer for意思是“为…喝彩叫好；为…鼓劲加油”,和cheer on意思基本一样.
其后必须加宾语,且宾语sb/sth都可以,同样sth作宾语少见.
但是for是介词,所以其宾语无论是名词还是代词,都直接放在for的后面.
如：We all cheered for him.
Why not cheer for his wonderful performance?
