【語法——動詞語態(tài)】，學(xué)習(xí)英語的話英語可是很重要的哦，大家趕緊；來5068頻道看看淺陌帶給大家的語法總結(jié)吧。
和時態(tài)一樣，語態(tài)也是動詞的一種形式，用來說明句中主語和謂語的關(guān)系。如果動作由主語執(zhí)行，就可使用主動語態(tài)，如果主語不是由主語執(zhí)行，主語是動作的承受者，則可使用被動語態(tài)。由此我們可以看出英語動詞有兩種語態(tài)：主動語態(tài)和被動語態(tài)。
被動語態(tài)：表示主語是動作的承受者，什么事情被主語做。被動語態(tài)的構(gòu)成和形式被動語態(tài)由"助動詞be+及物動詞的過去分詞"構(gòu)成，一定要記住是及物動詞。助動詞必須與主語的人稱和數(shù)一致，注意要與我們前一講學(xué)過的八個時態(tài)配合使用。
適合被動語態(tài)的情況：
不知道動作由誰發(fā)出，或由于某種原因沒有必要說明誰發(fā)出動作。如： This table is made of wood. 需要突出或強調(diào)動作的承受者時，如： This park was built for children.
注意：主動句中的主語如果是people，they，somebody等含糊的表示"人或人們"，沒有確指執(zhí)行者是誰，為被動句時，通常省略"by+執(zhí)行者"。如：The door was opened secretly. But nobody came in.
注意：在主動句里,不定式在make，see，hear等動詞后面作賓語補足語時都不帶to，但變成被動句時，后面的不定式都需帶to。如：He was made to do that work.
主動語態(tài)不能變被動語態(tài)的情況：學(xué)了被動語態(tài)，別以為主動句和被動句可以隨意轉(zhuǎn)換，千萬要注意呀!有些主動語態(tài)不能轉(zhuǎn)換成被動語態(tài)。當(dāng)賓語是反身代詞時, 如：You should take care of yourself. 當(dāng)謂語是表狀態(tài)的而不是表具體動作的及物動詞時，如：Does the skirt suit you?
