2、) him. 我喜欢你胜过喜欢他。2. 通常不与由 and 连接的两个比较级连用。如：误：Its colder and colder than ever误：Computers are cheaper and cheaper than before.误：She is more and more interested in English than last year.改正的办法：要么去掉后面的than结构，要么将and与一个比较级。如说成：It is colder than ever. 或 It is colder and colder. 等。3. than 通常用于两个不同的人或物在同一方面进
3、行比较，但有时指的可能是同一个人或物在同两个不同的方面进行比较。如：Hes more fat than (hes) short. 与其说他矮不如说他胖。They are more brave than wise. 他们有勇无谋。此类结构只能用 more 构成比较级，不能用-er 形式，即使是单音节也是如此。4. than any other后接名词时通常用单数形式，很少用复数。如：He swims faster than any other student in his class. 他比班上的其他任何学生都游得快。5. 当连接两个非谓语动词时，通常应保持用前后一致的形式。如：他认为他自己开车

6、earlier than was expected.正：He came earlier than he was expected.7. 带有never (a) 的比较级结构后连用了than时，是一种强调说法，通常表示最高级的含义。如：Ive never had a worse morning than today. 我哪一天早上也不像今天早上这样倒霉。若意思明确，有时可省略than结构。如：He is fine, never better. 他很好，比以往任何时候都好。Ive never found a better job. 这是我找到的最好的工作。8. 若语义需要，有时可后接when, if等引导的从句。如：You are a little fatter than when I saw you last. 你比我上次见你时胖点了。They work better together than if they are alone. 他们一起干比他们单干效果要好。有时还可接没有任何引导词的句子。如：The game was closer than the score suggests. 实际的比赛与所得的分数相比更难分高下。点击可查看更多关于高考英语的资讯：上海高考英语培训
