比較級使用than的常見語法難點

1、精選優(yōu)質文檔-傾情為你奉上一、后接人稱代詞用主格還是賓格由于than既可用作連詞也可用作介詞，所以當后接人稱代詞時，可用主格也可用賓格。通常認為在正式文體中多用主格，在口語或非正式文體中多用賓語。如：Everyone here is taller than I me. 這兒的每一個人都比我高。Her sister swims faster than she her. 她姐姐游泳比她快。但是，若人稱代詞之后跟有動詞，則只能用主格。如：Everyone here is taller than I am. 這兒的每一個人都比我高。Her sister swims faster than she do

2、es. 她姐姐游泳比她快。注意：有時用主格或賓格會導致意思的變化。比較：I love you more than he (likes you). 我比他更愛你。I love you more than (he likes) him. 我愛你勝過愛他。二、后接動詞用不定式還是動名詞1. 當連接兩個非謂語動詞時，通常應使用一樣的形式。如：It is much easier to get into debt than to get out of it. 借債容易還債難。He likes playing chess more than watching TV. 與看電視相比，他更喜歡下棋。比較：He

3、thinks it is safer to drive himself than (to) let me drive.=He thinks that driving himself is safer than letting me drive. 他認為他自己開車比讓我開車要更安全些。2. 若不是連接兩個非謂語動詞，則其后出現(xiàn)的動詞通常用動名詞形式(雖然也可用不定式，但不如用動名詞普通)。如：There are worse calamities than failing your driving test. 比起你駕駛考試不合格來說，更大的災難還多著呢。Nothing gives me more

4、 pleasure than listening to Mozart. 再沒有比聽莫扎特的樂曲更讓我高興的事了。Nothing is more unpleasant than finding to find insects in your bath. 最使人不快的是在浴室里發(fā)現(xiàn)有蟲子。三、引導比較狀語從句的時態(tài)問題若than引導的比較狀語從句與主句動作不一致，可以根據(jù)情況使用適當?shù)臅r態(tài)形式。如：He drives faster than he did a year ago. 他開車比一年以前快了。The house is rather bigger than we thought. 這所房子比

5、我們想的大得多。若主句為將來時，than引導的從句可用現(xiàn)在時態(tài)表示將來，也可直接使用將來時態(tài)。如：We'll probably drive faster than you do will. 我們開車可能會比你們快。四、引導比較狀語從句的倒裝問題than引導比較狀語從句時，從句語序通常不需倒裝，但在正式文體中，有時也可倒裝。如：City dweller have a higher death rate than country people do.=City dweller have a higher death rate than do country people. 城市居民死亡率比

6、農(nóng)村居民高。五、引導比較狀語從句且在從句中充當成分有時可引導一個從句并在從句中充當句子成分(主語、賓語、表語)，為便于理解，有時可視為than后省略了what：We don't want to do more than is necessary. 我們不想做不必要的事情。The pain was almost more than he could bear. 這樣的痛苦幾乎使他受不了。She's not a very good manager she always spends more money than she earns. 她不大會理財總是入不敷出。Life here

7、is much easier than it used to be. 如今在此地生活比起從前可舒服多了。比較下面一句，than后的expected為省略結構：He returned three days earlier than (he was) expected. 他回來得比預料的要早三天。六、后接時間或條件狀語從句若語義需要，有時其后可接when引導的時間狀語從句以及if 引導的條件狀語從句。如：You are a little fatter than when I saw you last. 你比我上次見你時胖點了。Joe carries only nine pounds more th

9、se. 他們有勇無謀。If we tell him about it, it may do more harm than good. 倘若我們把情況告訴他，那可能弊多利少。八、與never (a) 連用時如何理解有時than與帶有never (a) 的比較級結構連用，表示強調(diào)，通常表示最高級的含義。如：I've never had a worse morning than today. 我哪一天早上也不像今天早上這樣倒霉。若意思明確，有時可省略than結構。如：He is fine, never better. 他很好，比以往任何時候都好。I've never seen a f

10、iner bird. 我從未見過比這更美的鳥。I've never found a better job. 這是我找到的最好的工作。九、than any other后接名詞用單數(shù)還是復數(shù)than any other后接名詞時通常用單數(shù)形式，很少用復數(shù)。如：He swims faster than any other student in his class. 他比班上的其他任何學生都游得快。More heat is lost through the head than any other part of the body. 從頭部散發(fā)的熱量比身體的其他任何部位都多。十、幾組容易理解出錯
