求详细分析

Answer 1

拆开理解
They saw that nobody was very enthusiastic about it.
And they decided to cancel the trip.
把两句合起来就成了你的例句。
动词进行式和过去分词或者不定式可以用在状语里面表示一种状态。动词的形式就取决于动词所表示的动作与主语之间是什么联系。如果该动作是主语完成的，就用动词进行式表示伴随状态。例如：Seeing from the top of the mountain,we feel comfortable.在山顶上望去，我们感到心情舒畅。如果该动词与主语构成被动，那么就用过去分词，同样表示伴随状态。Seen from the top of the mountain,we are so small.（别人）看山顶上的我们如此的渺小。如果该动作是主语还未完成的意味，就用不定式，表示一种目的。例如：To be seen from the mountain,we were holding big flags with us .为了在山上时能被（别人）看到，我们举着大旗子.

追答

选B

我只知道这么点儿，希望对你有点点帮助。最好还是问问老师，查语法书确认一下

为什么不用when,因为句子里只能有一个主语，因此只能用动词分词来作状语表示状态

Answer 2

这题不需要知道意思都知道选择b，因为句子缺少主语，能做主语的只有b

Answer 3

由于的意思，复杂连词引导原因状语从句，和主句they构成主动关系，则应选现在分词结构B记得采纳！谢谢！
