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
