答案：
1. She had a guilty conscience (感到內(nèi)疚) about not telling the police what had actually happened.
(本題考查形容詞搭配，have a guilty conscience about意思為“內(nèi)疚”)
2. Many a time has the child been told not to play with fire (警告過那孩子不要玩火) but he turns a deaf ear to the warnings.
(本題考查倒裝結(jié)構(gòu)，此句中“but”是并列連詞，連接兩個并列句，狀語many a time放在句首，句子要倒裝)
3. In manufacturing industries some types of plastics have become a substitute for metal (取代了金屬).
(本題考查名詞辨析與搭配，名詞substitute?？荚嚧笥糜凇皊ubstitute for”結(jié)構(gòu)中，意為“替代”)
4.Without a sure supply of water, farming in that area remains at the mercy of the weather (靠天吃飯)
(本題考查mercy的用法，at the mercy of 意為“任憑…的擺布”“完全收…的支配”)
5.It was because she was inexperienced that she didn’t know how to deal with the situation (她不知道如何應(yīng)對這種形式)
(本題考查強調(diào)句型，這是一個it is …that…的強調(diào)句型，強調(diào)部分because she was inexperienced)
