(三) 正误辨析
［误］ Both my parents are not here. They went to the concert just now.
［正］ Neither of my parents is here. They went to the concert just now.
［析］ 在英语中both一般用于肯定句中，如用于否定句中，其意义也不同于汉语，如：Both of us are not right. 在英语中应被理解为"我们俩不都对。"而Neither of us is right。 才能被理解为"我们俩无一正确"。
［误］ He or his parents has some tickets for the film.
［正］ He or his parents have some tickets for the film.
［析］ 由or 连接两主语时，谓语动词应与相临近的那一个主语保持一致。
［误］ You should study hard, and you won't pass the exam.
［正］ You should study hard, or you won't pass the exam.
［析］ or作为连词，这里的意思为"否则"。又如：Hurry up, or you'll be late for school.
［误］ Though he is poor, but he is ready to help others.
［正］ Though he is poor, he is ready to help others.
［正］ He is poor, but he is ready to help others.
［析］ "虽然……但是"是中文中的常用结构，但在英文中用了"虽然"则不要用"但是"，用了"但是"则不能再用"虽然"，二者只可用其一。
［误］ Either you or I are on duty.
［正］ Either you or I am on duty.
［析］ either…or 连接两个主语时，其谓语动词与相临近的一个主语相呼应，这也叫作就近原则。类似的用法还有or, neither… nor, not only…but also等。
［误］ Tom is our English teacher and teaching English in our school now.
［正］ Tom is our English teacher and is teaching English in our school now.
［析］ 并列句中常常在后面的句子中作一些省略，以免重复，但不是所有词都可作任意的省略的。当你连接的是两个系动词时，后面的那个系动词不可省略，也就是讲连接的部分不可省略。
［误］ My father likes swimming and to collect stamps.
［正］ My father likes swimming and collecting stamps.
［析］ 由并列连词连接的两个部分要保持相等的语法结构。如是动名词则都用动名词，如用不定式则都应用不定式，这是初学者要注意的一点。
［误］ My father is reading a newspaper, I am doing my homework.
［正］ My father is reading a newspaper while I am doing my homework.
［析］ 两个并列句中间不可用逗号连接，要用并列连词来连接。
［误］ My father asked me that if I wanted to learn how to drive.
［正］ My father asked me if I wanted to learn how to drive.
［析］ 宾语从句的连接词只能有一个不能重复使用。
