英语练习题用所给动词的正确形式填空.I ________ (try ) to climb the tree ,but I
1:tried ,后面fauled就是过去式,前后要一致.
2:was writing when后面一般都是进行时.
3:put/puts[个人觉得一般式或过去式都可以]
4:couldn't find 前面looked已经是过去式了,后面也一样
5:was playing 一般while前后都是进行时,表示,他在做...而我在做...之类的意思.
6:correted/had correted,过去式或现在过去式,用后面那个比较好吧,因为corret发生在gave之前,要过去式的基础上再过去式一次.
7:phoned,解释同2
8:left,解释同2
9:happened, 后面有a week ago,就是过去式啦.
10:cut,cut的过去式也是cut.这里的while跟5不同,这里的while跟when表达方式一样.
