�。ǘ� 動(dòng)詞語態(tài)
1． 當(dāng)句子的主語是動(dòng)作的執(zhí)行者時(shí)， 謂語的形式叫主動(dòng)語態(tài)。句子的主語是動(dòng)作承受者時(shí)，謂語的形式叫被動(dòng)作語態(tài)。被動(dòng)語態(tài)由助動(dòng)詞be + 過去分詞構(gòu)成，時(shí)態(tài)通過be 表現(xiàn)出來。
1） 一般現(xiàn)在時(shí)：You are required to do this.

2） 帶不定式的被動(dòng)結(jié)構(gòu)：The room is going to be painted.
The homework needs to be done with care.
3) 短語動(dòng)詞的被動(dòng)：
a.（不及物）動(dòng)詞+介詞：若這類短語動(dòng)詞是及物性的，則可用于被動(dòng)語態(tài)中，如：laugh at, look after, talk about, think of 等。若這類短語動(dòng)詞是不及物性的則不可用于被動(dòng)語態(tài)中，如：book up, look down. 等

(比較：The classroom is always kept clean.)
5)主動(dòng)形式表示被動(dòng)意義的詞。常見的有：
a.主動(dòng)形式，這時(shí)動(dòng)名詞同句中的主語有動(dòng)賓關(guān)系。
The children need looking after.
The windows wants /requires repairing.
This point deserves mentioning.
b.有些及物動(dòng)詞后須加副詞 （如：well, easily等）， 有些可不加，如：act, clean, cut, draw, lock, open, play, read, sell, shut, strike, wash, write 等。
The cloth washes/ sells well.
The door won’t shut. The play won’t act.
c. 形容詞worth后直接加動(dòng)名詞時(shí)，如：The book is worth reading twice.
某些作表語的形容詞后，用不定式主動(dòng)形式表示被動(dòng)意義。
The fish is not fit to eat.
d. 某些感官動(dòng)詞（如：feel, look, prove, smell , sound, taste, wear等） 與形容詞連用時(shí)：The water feels very cold.

d. 賓語是反身代詞，相互代詞，同源代詞，不定式，動(dòng)名詞，抽象名詞等。
7）漢語有一類句子不出現(xiàn)主語，在英語中一般可用被動(dòng)結(jié)構(gòu)表示。如：
據(jù)說…… 希望……
據(jù)推測(cè)說… 必須承認(rèn)……
必須指出… 眾所周知……
有人會(huì)說….. 大家認(rèn)為…..
有人相信……
there be 小結(jié)
1. 基本結(jié)構(gòu) ：There be +主語 + 地點(diǎn) /時(shí)間狀語。如： There is a computer in the room. 房間里有一臺(tái)電腦�！here are two TV plays every evening. 每晚有兩場(chǎng)電視劇。
2. 主謂一致： 要采取就近一致原則，和* 近be的主語一致。如： There is a pen, two rulers in the box. 盒子里有一只鋼筆，兩把尺子。There are two boys and a teacher at the school gate. 門口有兩個(gè)男孩，一個(gè)老師。
3. 主語后的動(dòng)詞形式：在there be 句型中，主語與動(dòng)詞是主動(dòng)關(guān)系時(shí)用現(xiàn)在分詞；是被動(dòng)關(guān)系時(shí)用過去分詞。如： There is a purse lying on the ground. 地上有一個(gè)錢包。There are five minutes left now. 現(xiàn)在還有5分鐘。
4. 反意疑問句。反意疑問句應(yīng)與there be對(duì)應(yīng)，而不是依據(jù)主語。如：There is a radio on the table, isn't there? 桌子上有一臺(tái)收音機(jī)，是吧？ There are more than fifty classes in your school, aren't there? 你們班有50多名學(xué)生，是吧？
5. there be 與have的替換：there be表示所屬時(shí)可與have替換。 There is nothing but a book in my bag. =I have nothing but a book in my bag. 包里只有一本書。
6. there be后接不定式時(shí)常用主動(dòng)形式表示被動(dòng)意義。如：There is a lot of work to do. 有許多工作要做。注意：當(dāng)該句型主語是something, anything, nothing等不定代詞時(shí)，后面的不定式用主動(dòng)形式或被動(dòng)形式，意義各不同�！here is nothing to do. 沒有事可做�！here is nothing to be done. 沒有辦法(束手無策)。
7. 與其它詞連用，構(gòu)成復(fù)合謂語。如：There may be a rain this afternoon. 今天下午可能有雨。There used to be a cinema here before the war. 戰(zhàn)爭(zhēng)之前，這兒有一家電影院。
8. 變體 there be結(jié)構(gòu)中的be有時(shí)可用live, stand, remain等代替。如：Once there lived a king who cared more about new clothes than anything else. 從前有位國王喜歡新服勝過別的任何東西。
9. 習(xí)慣用語：There is no good /use (in) doing sth. 做某事沒有好處/用處；There is not a moment to lose. 一刻也不能耽誤。例如：There is no good making friends with him. 和他交朋友沒有什么好處�！e is very ill. Send him to hospital. There's not a moment to lose. 他病得厲害，把他送到醫(yī)院去，一刻也不能耽誤。
