英語從句語法:從句的改寫方法
1.用“連詞+分詞”來替代從句
當主句和從句的主語一致,謂語的時態(tài)又是同時段發(fā)生,可以把從句的主語省去,變謂語動詞為現(xiàn)在分詞或過去分詞。如果分詞的邏輯或時間意義不明確,還可以保留連詞。
例1:Guests mingle while enjoying cake, punch and other treats.
例2:While speaking out against Hitler’s atrocities, the American people generally favored isolationist policies and neutrality.?
例3:Plastics are materials which are softened by heat and set into lasting form when shaped in a mold.
注:如果從句的謂語是系動詞be,在簡化句型時應該把be動詞改成being,但是由于being語義意義,所以可以省略,這樣就造成了形容詞作狀語了。
例1:These apples, when ripe, are picked.?
例2:She knows all the hazards of smoking while pregnant.?
2.?用“介詞+分詞”來替代從句
一般說來,用on和at表示“as soon as, once”。on后面常接“來、去”之類的詞,at后面常接“聽到、看到”之類的詞。in后面接其他帶動作的詞,相對于從屬連詞“while”。
例1:On removing them he was stunned to see that the plates were fogged where the crystals had covered them.?
例2:In running down the stairs, I heard the clock struck twelve.
例3:He jumped with joy at hearing the news.?
3.?用“介詞+動作性名詞”來替代從句
同上面一樣,At基本上后接sound,sight“聽到、看到”之類的詞;on接“回來、到達”之類的詞;用in,during表示“when, while”;用over表示“while”之意。當然,這一切都是相對的分類。
例1:The little girl passed out at sight of a snake.?
例2:In our hurry to get from one place to another, we failed to see anything on the way.?
例3:On arrival at the railway station, he found the train had already left.?
例4:He had intended to go, but on second thoughts, he gave up the idea.
例5:During my absence, would you please take care of my cat?
例6:He fell asleep over a book.?
例7:After reelection he announces that he will not help.?
例8:After graduation, he went to America for his PhD studies.
4.?用“并列句”代替
例句:Two other poses were tried and I emerged from the booth to find a lot people waiting for my signatures.
