1樓：紅月亮
你好，句子是：
some students are singing in the classroom .
一些學生正在教室裡唱歌。
what's on the wall ？
牆上有什麼？
對there be 句型中的名詞提問時，不管名詞是單數還是複數，都用 what is +地點 提問。
這是固定用法。
2樓：艾薇
the students in the classroom are singing.
3樓：匿名使用者
some students are singging in the classroom.
(the students)are singing in the classroom.就括號部分提出問題
4樓：
who is
畫線部分是主語
所以用who
因為提問的時候不知道人稱是單數還是複數
所以統一用單數is
5樓：大漠荒延
who is
對主語是人的用who提問，who被看作是單數名詞，謂語動詞用單三。
some students are in the classroom.(改為同義句)
