31、的意思。 2【教材原句】　They say that the low-temperature lake is unlikely to be able to support such large living creatures.(P52) 他們說，水溫這樣低的湖泊不可能生存有體形如此巨大的動物。 【句法分析】　(1)本句可以轉化為：They say that it is unlikely that the low-temperature lake is able to support such large living creatures. (2) 本句使用了be unlikely t

32、o do sth.這一結構，它的用法等同于be likely to do sth.。主要有下述用法： 主語(具體人/物)＋be (un)likely to do sth. It(形式主語)＋be (un)likely to do sth. It(形式主語)＋be (un)likely＋that-clause 【注意】　likely與unlikely不能用于It’s likely/unlikely for sb.to do sth.，而possible與probable是可以用于It’s possible/probable/impossible for sb.to do sth.。另外，

33、(be)possible與(be)probable的主語不能是具體的某人或某物。 ①Look at the clouds！It’s likely to rain. 看那些烏云！天可能要下雨。 ②It’s too late.He is unlikely to come. 太晚了。他不可能來了。 ③It’s likely that we will beat them since we have practiced a lot. 因為我們做了大量練習，很可能我們會打敗他們。 ④He is ill seriously so that it’s unlikely that he will

37、should choose to read since if they read bad books，it will be timewasting and harmful. It must be realized that people should be cautious deciding which books they should choose to read since reading bad books is timewasting and harmful. 【分析】　把“when they decide”改為“deciding”，if 條件從句改為動名詞短語作主語，句子結

38、構變得更加緊湊，簡潔明了。 【佳句選粹2】 【原文】 【優(yōu)化】 Because I was ill，I didn’t go to the party.The party was organized by my classmates yesterday. Being ill，I didn’t go to the party which was organized by my classmates yesterday. 【分析】　把原句中的原因狀語從句用分詞的形式變換，又用了個定語從句把兩個句子連起來，使得句子更緊湊，更嚴謹。 2.強調句的變換 寫作中，常使用強調句來達到突

39、出重點的目的。強調句的基本結構是：It is/was＋被強調部分＋that/who＋句子其他成分。另外，英語中還經常使用助動詞do/does/did對謂語動詞進行強調。 【原文】 【優(yōu)化】 I met a friend of mine in the street yesterday. It was in the street that I met a friend of mine yesterday. 【分析】　改成強調句后，強調說明是“in the street”而不是別的地方，句意的表達更加有力。 【佳句選粹1】 【佳句選粹2】 【原文】 【優(yōu)化】 We shoul

40、d be careful when we cross the street. Do be careful when we cross the street. 【分析】　改成強調句后，語氣增強了，句意的表達更加有力，可翻譯為“過馬路時務必要小心”。 3.倒裝句的變換 句子成分在句子中都有一定的位置，但有時可以把某些句子成分前后倒置，以達到突出強調的目的或起到某種修飾作用。 英語中倒裝分為全部倒裝和部分倒裝。部分倒裝在寫作中比較常用，經常由否定詞提前或“only＋狀語”提前引起。 【原文】 【優(yōu)化】 Everyone knows that we are busy all day.We know seldom what is happening both at home and abroad，let alone what we can do for our country. Everyone knows that we are busy all day.Seldom do we know what is happening both at home and abroad，let alone what we can do for our country. 【分析】　“seldom”位于句首，引起部分倒裝，突出了現在時態(tài)，句意表達更有力。
