1、Section Grammar,,探究 語法精要,被動(dòng)語態(tài) 英語動(dòng)詞有兩種語態(tài)：主動(dòng)語態(tài)和被動(dòng)語態(tài)。 當(dāng)主語為動(dòng)作執(zhí)行者即施動(dòng)者時(shí)，動(dòng)詞用主動(dòng)語態(tài)；如果主語是動(dòng)作的承受者即受動(dòng)者時(shí)，動(dòng)詞用被動(dòng)語態(tài)。 一、被動(dòng)語態(tài)的構(gòu)成 被動(dòng)語態(tài)由助動(dòng)詞be和及物動(dòng)詞的過去分詞構(gòu)成。 被動(dòng)語態(tài)可用于各種時(shí)態(tài)，其時(shí)態(tài)變化通過助動(dòng)詞be的不同形式來體現(xiàn)。,二、主動(dòng)形式表示被動(dòng)意義 1英語中有很多動(dòng)詞，如break，catch，clean，drive，lock，wear，open，sell，read，write，wash等，當(dāng)它們被用作不及物動(dòng)詞來描述主語特征時(shí)，常用其主動(dòng)形式表達(dá)被動(dòng)意義，主語通常是物；在這種情況下

3、th的后面，動(dòng)名詞用主動(dòng)形式表示被動(dòng)意義，其含義相當(dāng)于動(dòng)詞不定式的被動(dòng)形式。 The house his grandmother lives in needs repairing/to be repaired. 他祖母住的房子需要維修。 The picture book is well worth reading. 這本圖畫書非常值得一讀。,三、主動(dòng)表示被動(dòng)的句式 在“主語(人/物)be形容詞不定式”結(jié)構(gòu)中，不定式的主動(dòng)形式可表示被動(dòng)意義。這些形容詞有nice，easy，fit，hard，difficult，important，impossible，pleasant，interesting等。

4、 This problem is difficult to work out. 這道題很難計(jì)算出。 As you know，Chinese is difficult to learn，especially for a foreigner. 正如你所知，漢語難學(xué)，尤其是對(duì)一個(gè)外國人來說。,四、get/remain動(dòng)詞的過去分詞 Many peoples names got changed in the rush. 很多人的名字在匆忙之中被改了。 You might get burnt and you might drop the pan of burning oil. 你有可能被燙傷，也可能會(huì)打
