四. 語(yǔ)法：
被動(dòng)語(yǔ)態(tài)：被動(dòng)語(yǔ)態(tài)表示主語(yǔ)是句中的動(dòng)詞即謂語(yǔ)動(dòng)詞的承受者，被動(dòng)語(yǔ)態(tài)常常用by短語(yǔ)來(lái)說(shuō)明動(dòng)作的執(zhí)行者，如，These books were all written by Lu Xun.（這些書(shū)都是魯訊寫(xiě)的）。當(dāng)不強(qiáng)調(diào)動(dòng)作執(zhí)行者時(shí)，by短語(yǔ)就可以省略。由于不及物動(dòng)詞不能帶賓語(yǔ)，因此它沒(méi)有被動(dòng)語(yǔ)態(tài)。
被動(dòng)語(yǔ)態(tài)的結(jié)構(gòu)：動(dòng)詞的被動(dòng)語(yǔ)態(tài)形式由助動(dòng)詞be + 及物動(dòng)詞的過(guò)去分詞(done)構(gòu)成。助動(dòng)詞be 必須和主語(yǔ)的人稱和數(shù)一致，并且表示出時(shí)態(tài)、語(yǔ)氣等。
被動(dòng)語(yǔ)態(tài)的用法：
1. 只知道動(dòng)作的承受者，不知道動(dòng)作的執(zhí)行者。
The watch was passed up to the woman.
手表傳給了那位婦女。
2. 沒(méi)有必要指出動(dòng)作的執(zhí)行者。
The classroom is cleaned every day.
教室每天都打掃。
3. 有必要強(qiáng)調(diào)或突出動(dòng)作的承受者。
Thanks. My pen has been found.
謝謝你。我的鋼筆已經(jīng)找到了。
4. 有些動(dòng)作習(xí)慣上用被動(dòng)語(yǔ)態(tài)。
His father was born in 1962.
他爸爸生于1962年。
五. 具體內(nèi)容：
Section A:
1. I think the telephone was invented before ( after ) the car.
我認(rèn)為電話是在汽車之前（之后）發(fā)明的。
2. It’s used for scooping really cold ice cream.
它是用來(lái)舀特別涼的冰淇淋用的。
be used + 介詞結(jié)構(gòu)的幾種常見(jiàn)用法：
1）be used for 意為“被作為……使用”，“用來(lái)作……”，“為了……而使用”。
Bamboo can be used for carrying water.

3. discover, find out 和invent的區(qū)別。
discover, find out 和invent都有“發(fā)現(xiàn)”的意思，但各自又有自己的特點(diǎn)。
