She is a lovely girl改成一般疑問句是：

Is she a lovely girl?

這是一個含連繫動詞be的陳述句，如果變成一般疑問句，只需要將be動詞（is are am was were )提到句首即可。例如：

1. John is fond of pop music.

Is John fond of pop music?

2.All the children were very happy when they heard the good news.

Were all the children very happy when they heard the good news?

這道題有點錯誤，應該是She is a lovely girl.那麼這個句子變成一般疑問句時，應該是這樣的：Is she alovely girl？

這種主系表結構的句子變成一般疑問句是有規律的，那就是把系動詞提到主語前並大寫，原主語小寫放在系動詞後，再加上表語就可以了。
