動(dòng)詞的語(yǔ)態(tài)

動(dòng)詞的語(yǔ)態(tài) ：

語(yǔ)態(tài)是動(dòng)詞的一種形式，表示主語(yǔ)和謂語(yǔ)的關(guān)系。語(yǔ)態(tài)有兩種：主動(dòng)語(yǔ)態(tài)和被動(dòng)語(yǔ)態(tài)。
主語(yǔ)是動(dòng)作的發(fā)出者為主動(dòng)語(yǔ)態(tài)；The cat caught the mouse.
   主語(yǔ)是動(dòng)作的接受者為被動(dòng)語(yǔ)態(tài)。被動(dòng)語(yǔ)態(tài)由“助動(dòng)詞be+及物動(dòng)詞的過(guò)去分詞”構(gòu)成。助動(dòng)詞有人稱，數(shù)和時(shí)態(tài)的變化，起變化規(guī)則和be作為連系動(dòng)詞時(shí)完全一樣，以ask為例說(shuō)明被動(dòng)語(yǔ)態(tài)的構(gòu)成。
一般現(xiàn)在時(shí)  am/ are / is asked
一般過(guò)去時(shí)  was/ were asked
一般將來(lái)時(shí)  shall /will be asked
現(xiàn)在進(jìn)行時(shí)  am/ are/ is being asked
現(xiàn)在完成時(shí)  have/ has been asked
過(guò)去進(jìn)行時(shí)  was/ were being asked
過(guò)去將來(lái)時(shí)  should/ would be asked
過(guò)去完成時(shí)  had been asked

   被動(dòng)語(yǔ)態(tài)的疑問(wèn)句是將肯定句將肯定句中的第一個(gè)助動(dòng)詞移到主語(yǔ)之前，否定句是在第一個(gè)助動(dòng)詞后面加not。如：
   肯定句：They are made in China.
   疑問(wèn)句：Are they made in China?
   否定句：They are not made in China.
