本單元常見錯誤分析
1． 誤：Don’t touch anything unless your teacher tells you.
正：Don’t touch anything unless your teacher tells you to.
說明：省略賓語補足語時，to 不可省略。
又如: Would you like to go to the zoo with me?
Yes, I’d like to.
2. 誤：After that, he held up one of his fingers and showed to the class.
正After that, he held up one of his fing ers and showed it to the class.
少了作賓語的it,就成了漢語式英語。換句話，這個錯誤實際上是尚未擺脫母語表達習慣的表現。
3.誤： He put a finger in his mouth, tasted it and smiled, looked rather pleased.
正：He put a finger in his mouth, looking rather pleased.
作為謂語動作的伴隨動作應用現在分詞的形式。如果用looked,前面須由連詞 and 連接，以表示并列關系。
4．誤： The mixture tasted terribly.
正：The mixture tasted terrible.
句中tasted是聯系動詞，故其后作為表語的成分應是形容詞。類似的動詞還有feel, smell等。如 The flower smells sweet.
5. 誤： The book is sold well.
正：The book sells well.
Sell是不及物動詞，不及物動詞無被動語態。
6．誤 Let each of us recite their poems./ let each of us recite our poems.
正：Let each of us recite his poem(s).
each是單數，而且each of us是第三人稱，不是第一人稱，因而應用his poems.
7． 誤：They each other take care of.
正：They take care of each other.
Each other是代詞而非副詞，應放在賓語的位置上
8． 誤： all her brothers are not at home.
正： None of her brothers are at home.
第一句是部分否定（not 與all連用為半否定“她的兄弟并不是全不在家”）第二句才是“沒有一個兄弟在家”
9． 誤： Neither of them saw each other.
正：Neither of them saw the other.
Each other一定是指復數的名詞或代詞而言的， 由于neither of them只表示單數，后面也就不能用each other.
