2017屆中考英語連詞語法復習
［誤］ my brother will pass the english exam is no question.
［正］ that my brother will pass the english exam is no question.
［析］ 主語從句的引導詞that是不可省略的。這一點不要和賓語從句的引導詞相提并論。
［誤］ this map will show you how will you get to the hotel.
［正］ this map will show you how you will get to the hotel.
［析］ 名詞性從句作賓語從句使用時，最重要的一點是要用陳述語句。特別要注意的是那些使用雙賓語的動詞，如：tell, ask, show…
［誤］ while the clock struch ten, all the lights went out.
［正］ when the clock struck ten, all the lights went out.
［析］ while是強調兩個動作在同時進行中，如：while i am doing myhomework, my father is reading a newspaper. 而這里的when是"正當某某時刻"，"就在這一時間點上"，其重點強調在某一特定時刻某動作的發生。
［誤］ while i was walking along the street yesterday, i met an old friend.
［正］ when i was walking along the street yesterday, i met an old friend.
［析］ 這里用when表達在一個動作的進行中，另一個動作突然發生了。正在進行的動作用一進行時態，而突然發生的動作用一般時態。
［誤］ while i heard the bad news i felt sad.
［正］ when i heard the bad news, i felt sad.
［析］ while不能表達一點兒的時間，即瞬時某一時間點。
［誤］ after school some students play football, or others go to the library.
［正］ after school some students play football, while others go to the library.
［析］ while在此處意為"而，然而"。
［誤］ she sang when she walked along the dark street.
［正］ she sang as she walked along the dark street.
［析］ as用于句中時，其要點是強調兩個動作的同時進行。這里用when雖然不能講是語法上的錯誤，但則看不出來小女孩因獨自走黑暗的街道因害怕而唱歌的心情。
［誤］ i finished my homework until twelve o'clock last night.
［正］ i didn't finished my homework until twelve o'clock last night.
［正］ i did my homework until twelve o'clock last night.
［析］ until用在句中時其含義是某一動作一直持續到某時結束，那么句中的動詞則一定要用持續性動詞，如果要用瞬間，或截止性動詞時一定要用否定句式。因截止性動作的否定式應看作是持續性的動作。如離開leave是瞬間動作，因一出門即為離開了，而不離開則是長時間的。
［誤］ i have studied english when i was twelve.
［正］ i have studied english since i was twelve.
［析］ since引出的時間狀語從句是表達了一個時間點，而這個時間點是主句動作的啟始點，所以主句一般要用完成時態。
［誤］ because he didn't study hard, so he didn't pass the exam.
［正］ he didn't pass the exam because he didn't study hard.
［析］ because 與 so在英文中兩者不能并用的，只能在句中用其一。
［誤］ he was such excited that he could not speak.
