高一英语必修3内容要点

           11. look forward to (doing) sth. 意为期待着(做)某事, 其中的to是介词, 而不是动词不定式符号。 12. as though和as if没有什么区别。as if用得普遍些, 却可引导方式状语从句和表语从句, 其从句谓语常用虚拟语气。

(1) 引导方式状语从句 She acted as though nothing had happened． 她装得好像什么事也没发生过似的。当从句主语和主句主语一致,从句谓语中又含有动词to be时, 可以把主语和to be一起省去。 He looked about as though (he was) in search of something． 他四处张望, 好像寻找什么。

 (2) 引导表语从句 It looks as if it’s going to rain看样子天要下雨 as though和as if从句用虚拟语气,还是用陈述语气。完全根据具体情况而定。如果从句表示的意思与事实完全相反,或者纯粹是一种假设, 通常用虚拟语气。 The child talks as if she were an adult. 那孩子说话的样子好像她是个大人。

 13. have fun意为“过得快乐”同义词组为have a good time, enjoy oneself. 短语有have fun ( in ) doing sth. 14. But she didn’t turn up.

1) 来, 出席(某活动) I’m very happy you turned up so early.

2) 把(收音机等)音量开大一些, 其反义短语是turn down. Turn up the radio a little, I can scarcely hear the program. 相关短语: turn down 拒绝 turn off 关掉 turn on 打开 turn out 结果是..... .turn to sb. for help 向某人求助

 15. keep one’s word 意为“守信用”,其反义词是break one’s word, 即“失信”。 注意：keep one’s word和break one’s word中的名词word不能用复数形式。相关短语： in a word/in short/to be short 简言之；总之 have a word with sb. 与某人谈话 have words with sb. 与某人发生口角 in other words 换句话说 16. obvious adj.

1) obvious+ to + 表示人的名词或代词 Her disappointment was obvious to her friend.

 2) It + be + obvious +that-clause It was obvious that she was in danger. 辨析：obvious/apparent/clear

 1) obvious 是三者中程度最强的，含有“一目了然” 之意。 It is obvious that you are wrong.

2) apparent 指具有某些明显的迹象的，侧重与经历推理才能看出结果。 It was apparent from his face that he was lying.

3) clear 作“明白的，清楚的”讲。指不模糊含混，易于观察，了解和识别。 He seems clear about his plans. 17. marry 的用法：

1) 她嫁给了一个律师。 She married a doctor. 表示“和......结婚”，“嫁......”，“娶......”时，marry为及物动词，要用marry sb.，而不用marry with sb.
