呃,答案我知道,想问一下每题的原因(打括号的是答案)
1.固定形式,go和shop均是动词,一个句子不能用两个谓语动词,后面一个要改为非谓语形式
2.keep+动词ing形式
3.祈使句。。
GO SHOPPING 是固定搭配 ,就像上学用GO TO SCHOOL一样
KEEP (ON)DOING STH 是一个固定搭配,表示持续不断做某事
第三个好象不太明白,我觉得应该是WAIT FOR ME 不是WRITE FOR ME
整句的意思就是请等我一回,我马上来
1. go shopping 固定搭配
2. keep doing 同上
3. 祈使句动词原形开头
go shopping.去购物. keep sb. doing sth.让某人一直做某事 第三题该是wait吧?wait for sb.等某人
1.go shopping 固定搭配,购物
2.keep+动词ing形式
3.祈使句动词原形引导的啊
