　　1. 正確答案為A項。本題考查動詞forbid的用法。當動詞直接作該詞的賓語時，應使用動名詞的形式，構成forbid doing這種表達。需要補充的是，當表達“禁止某人做某事”的時候，則是forbid sb. to do sth. 。句子譯文：“有一項規(guī)章禁止在公共場所吸煙。”

　　2. 正確答案為C項。本題考查動名詞的復合結構作主語。A項的語法錯誤，應更改為That the girl was educated，成為從句作主語。B項的表達是過去分詞作定語，修飾the girl，這樣一來，主語的核心詞是the girl，這與表語what her parents wished for(她父母所希望的事情)不能對應。D項的表達是不定式作作定語，修飾the girl，主語的核心詞仍然是the girl，這和B項一樣，主語和表語不能對應。句子譯文：“這個女孩在簡樸的生活氛圍中接受教育，這是她的父母所希望的。”

　　3. 正確答案為D項。形容詞enough之后的動詞應使用不定式。句子譯文：“今晚不會冷到下霜的程度，所以我可以安全地把吉姆的車停在外面。”

　　4. 正確答案為D項。動詞expect之后接不定式作賓語，當然也可以接賓語從句。本句既可以說The students expected there to be more reviewing classes before the final exam. ，也可以說The students expected there will be more reviewing classes before the final exam. 句子譯文：“學生們希望在期末考試前有更多的復習課。”

　　5. 正確答案為B項。本題考查不定式的復合結構作目的狀語。句子譯文：“為了成功交流，所有與會者都必須認真聽取意見并參與討論。”
