本单元常见错误分析
1． 误：Don’t touch anything unless your teacher tells you.
正：Don’t touch anything unless your teacher tells you to.
说明：省略宾语补足语时，to 不可省略。
又如: Would you like to go to the zoo with me?
Yes, I’d like to.
2. 误：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.
少了作宾语的it,就成了汉语式英语。换句话，这个错误实际上是尚未摆脱母语表达习惯的表现。
3.误： 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.
作为谓语动作的伴随动作应用现在分词的形式。如果用looked,前面须由连词 and 连接，以表示并列关系。
4．误： The mixture tasted terribly.
正：The mixture tasted terrible.
句中tasted是联系动词，故其后作为表语的成分应是形容词。类似的动词还有feel, smell等。如 The flower smells sweet.
5. 误： The book is sold well.
正：The book sells well.
Sell是不及物动词，不及物动词无被动语态。
6．误 Let each of us recite their poems./ let each of us recite our poems.
正：Let each of us recite his poem(s).
each是单数，而且each of us是第三人称，不是第一人称，因而应用his poems.
7． 误：They each other take care of.
正：They take care of each other.
Each other是代词而非副词，应放在宾语的位置上
8． 误： all her brothers are not at home.
正： None of her brothers are at home.
第一句是部分否定（not 与all连用为半否定“她的兄弟并不是全不在家”）第二句才是“没有一个兄弟在家”
9． 误： Neither of them saw each other.
正：Neither of them saw the other.
Each other一定是指复数的名词或代词而言的， 由于neither of them只表示单数，后面也就不能用each other.
