專題六：連詞

1、專題六 連詞易錯清單1. as,while,when,as 用作連詞時,含義比較多,A)引導(dǎo)時間狀語從句。(1)用“as soon as”結(jié)構(gòu),意思是“一……就” 。例如:Please e-mail me as soon as you get there.請你一到那里就給我發(fā)電子郵件。I'll tell him the news as soon as he comes back.他一回來我就把這個消息告訴他。(2)作“與……同時

2、、一邊……一邊、當(dāng)……的時候”講時,強調(diào)主從句的動作同時發(fā)生,而從句的謂語動詞必須是延續(xù)性動詞。例如:He read the letter as he walked along the river.他一邊沿著河邊走,一邊讀信。As I waited at the stop, I heard a big noise.我在車站候車的時候,聽到了一聲巨響。B)引導(dǎo)比較狀語從句。用于“as...as”結(jié)構(gòu)中,第一個 as 是副詞,第二個 as

3、是連詞。否定句用 not as/so...as 結(jié)構(gòu)。例如:He sings as well as his brother. 他唱歌和哥哥一樣好。Canoeing is not as/so interesting as sailing.劃獨木舟沒有航海有趣。C)引導(dǎo)原因狀語從句。表示明顯的原因,意思是“由于、鑒于” 。例如:We all like her as she is kind. 我們都喜歡她,因為她善良。As you'r

4、e tired, you'd better have a rest. 因為你疲勞,你最好休息一下。D)引導(dǎo)讓步狀語從句。作“雖然、盡管”講時,相當(dāng)于 though,但是沒有 as 常用。例如:As/Though they were tired,they still walked on. 盡管很累,他們還是繼續(xù)走。 (=Tiredas/though they were,they still walked on.)As I like

5、 it,I will not buy it.雖然我喜歡這個東西,但是我不想買。E)引導(dǎo)方式狀語從句,意為“按照、如同” 。如:When the game began,I was waiting for a taxi.當(dāng)比賽開始時,我在等出租車。when 可以引導(dǎo)賓語狀語從句,后面跟陳述句語序,意思是“什么時候、何時” 。如:Please tell me when you came here.請告訴我你是什么時候到的。He asked w

6、hen the game would start.他問比賽什么時候開始。when 用作疑問副詞,意為“什么時候、何時”,引導(dǎo)特殊疑問句,可以問時間點,也可以問時間段。如:—When do you usually go to school every day?——你每天通常什么時候上學(xué)?—At six o'clock.——六點鐘?！猈hen will he be back?——他什么時候回來?—In a week.——一個星期以后

7、。—When were you born?——你是什么時候出生的?—I was born in 1995.——我出生在 1995 年。while 用作連詞時,意為“當(dāng)……的時候、和……同時”,引導(dǎo)時間狀語從句,從句只能指時間段,不能指時間點,謂語動詞必須是延續(xù)性動詞或狀態(tài)動詞。如:Strike while the iron is hot. 趁熱打鐵。Somebody broke into the house while we were
