网友回答
(答案→)1.went后加for
解析：
1.went后加for go后可以接v.ing;to do sth.;for sth.
2.well→fine/nice well作“健康”讲是adj.，作“好”讲是adv.。
3.could→clouds 应该用复数，否则为...was not a cloud
4.blown→blowing start后可以接to do或doing.
5.去掉were 此处应该用主动语态
6.but→so 前后为因果关系。
7.第一个a→an hour为元音音素开头。
8.正确。
9.must→should,must have done 表示现在对过去的推测；should have done表示过去该做的事而没有做，且带有责备意味。
10.去掉第二个to but前面有do的不同形式时，后面的不定式不带to。
