用名词，且此处用名词复数形式表泛指。

　　4．who　考查定语从句的引导词。分析句子结构可知，空处引导定语从句，修饰先行词person，并在定语从句中作主语，故用who。

　　5．successful　考查词性转换。分析句子结构可知，空处在句中作表语，故用形容词successful。

　　6．a　考查冠词。此处指让你的孩子住在一个大房子里，表泛指，故用不定冠词，结合空后的big可知，应填a。

　　7．it　考查代词。你割草时让他们来体验一下。此处用it指代割草这件事。

　　8．because　考查连词。这样做并不是因为你没钱雇女仆。空后解释的是原因，故用because。注意：本句为省略的强调句，只能用because，不用since/as/for。

　　9．to understand　考查非谓语动词。want sb.to do sth.为固定用法，意为"想要某人做某事"。

　　10．how　考查疑问词。分析句子结构可知，此处是"疑问词＋不定式"结构作宾语，且表示"如何......"，故用how。

　　Ⅳ.短文改错

　　This morning I lost my MP3 player on my way to school. It was bought with the money I had been saved for months. Too upset was I that I could hardly concentrate in what the teacher was saying. After class, my head teacher called me out and asked if or not I had lost something. It turned out that my MP3 player slipped out of my pockets while I was walking. And fortunately, a young lady walked behind me noticed it. She found the school guard and gave them to him.

　　How excited and how deep moved I was to get my MP3 player back! I want to be kind person like the lady.

　　答案：

　　难项分析：

第一处：去掉been　考查动词的语态。此句中the money为先行词，其后为省略了关系
