8-5 问句的被动语气
将问句改成被动语气，步骤类似上一节的步骤，我们先将问句变成肯定句子，然后将这个定句子变成被动语气，最后在将这个被动语气的句子变回，成为问句。
例如：
Do young kids enjoy classical music?
先改成肯定句子
Young kids enjoy classical music.
再改成被动语气
Music is enjoyed by young kids.
最后改成问句
Is music enjoyed by young kids?
为了使读者熟悉这些步骤，我们在下面举了很多的例子：
1. Did you eat that cake?
(a).You ate that cake.
(b).That cake was eaten by you.
(c).Was that cake eaten by you?
2.Do farmers in Taiwan grow apples?
