有些问题，答案只有“Yes”或“No”，以下是一些例子。
原来句子

Does he have a car？

Did I give him three books？

根据以上的例子，我们可以归纳乘以下的规则：
凡动词是verb to be的，变成问句时，动词移到主词前面去。
例子：
原来句子
问句

Are you a girl？
He was a teacher.

They were all old.

动词不是verb to be，也没有助动词，改成问句时，必须加助动词do或他的变形，这个助动词必须在主词的前面。
例子：

句子中间如已有助动词，改成问句时，只要将助动词移到主动词前面即可。
例子：
原来句子

我们的问句中，当然也可已有否定的意义，比方说，我们可以问：
你不喜欢音乐吗？
他不是你的弟弟吗？
你从未见过他？
英文句子也可以如此，例如：
Don't you like music？
Doesn't he play piano？
Aren't you his brother？
Isn't he a good student？
Didn't he go to school？
Hasn't he lived here？
Won't he leave tomorrow？
注意，这时not通常和动词连在一起了。 << 上一页 [11] [12] [13] [14] [15] [16] [17] [18] [19] [20] ... 下一页 >> |
