2、 that ”的被動(dòng)語態(tài)。類似結(jié)構(gòu)還有：It is thought that；It is reported that ；It is believed that ；It is hoped that等。as it is 也是固定的結(jié)構(gòu)，解釋“根據(jù)現(xiàn)在情況看；就以現(xiàn)在樣子”，常用于句子開頭或結(jié)尾。例如：I thought things would get better, but as it is they are getting worse.我原以為情況會(huì)好轉(zhuǎn)，但照現(xiàn)在的樣子看，只會(huì)更糟。2. For women it sometimes seems twice as difficult. 對(duì)婦女來

3、說，有時(shí)生活似乎是難上加難。該句相當(dāng)于For women life sometimes seems twice as difficult as it is.倍數(shù)的表達(dá)法可以有以下幾種表示：The room is twice bigger than mine.The room is twice as big as mine.The room is twice the size of mine.注意：倍數(shù)詞總是位于第一as前，并且第二個(gè)as在上下文意義明確的情況下可省略。例句：The house rent is expensive.

4、ad at home and Im paying _ here.A. as three times muchB. as much three timesC. much as three timesD. three times as much分析：本句為asas 比較結(jié)構(gòu)，much后省略了as I paid at home.表示：“我現(xiàn)在所付竟然是原來的三倍”，three times 應(yīng)放在as much 之前。故選D。3Do you know a woman who really inspires you?你認(rèn)識(shí)一位真正感動(dòng)你的女士嗎？inspire為及物動(dòng)詞，意為“鼓舞、感動(dòng)”。如：Were

7、o you think+疑問句的其他部分（陳述語序）”。如：Who do you think has taken his wallet?你認(rèn)為誰拿了他的錢包？What do you think I have bought for you?你猜我為你買來了什么？可以這樣用的動(dòng)詞還有suppose, guess, believe, imagine, expect.6What else, but a journey at the opposite end of the world, Antarctica?除了去世界另一頭南極洲旅行，還會(huì)干什么呢？這是一句省略句，完整的結(jié)構(gòu)是：What else wo

8、uld I do but a journey at the opposite end of the world, Antarctica?句中的but是介詞，意為“除了”，相當(dāng)于except，常與不定代詞、疑問代詞等連用。例如：In winter, bears can do nothing but lie down and sleep.在冬天，熊只能躺下睡覺。else是個(gè)形容詞，意為“其他的，別的”，不作前置定語，只能用在疑問詞where, what, which, who等或不定代詞something, anything等后，表示追加說明。如：Is there anything else yo
