11.The singer and dancer_______come to our city.

10和11题有什么区别?为什么10题选A而11题选B?
2,room's numbers房间的号码,所以room要加's构成名词所有格,room numbers只表示房价号码.number是可数名次,当然有复数了.
5.He_______ten years old next year.
is going to be是按计划准备做什么事情,这里是客观的.
.

shall在这里表示许诺的意思,其他不行.
9.All作整体名词时用单数.
10.The singer and the dancer,两个the表示的是一个歌手和一个舞蹈家,两个人,用have,复数.
11.The singer and dancer,一个the指这个人既是歌手又是舞蹈家,只一个人,用单数.
