Answer:兩句都不正確
錯(cuò)誤的原因在于:當(dāng)你把陳述句變?yōu)楸粍?dòng)句時(shí),賓語(yǔ)提前放到了句首,句子就不再有賓語(yǔ)了.如果還想表明謂語(yǔ)動(dòng)作的施動(dòng)者是誰(shuí),那就在句尾加上"by + 動(dòng)作施動(dòng)者(原來(lái)的主語(yǔ))"
以上兩句可改為:
I was seen to sing by him .
I was being seen singing by him.
(注:這里"singing"和"to sing "仍然是"I"的補(bǔ)語(yǔ),只不過(guò)變成被動(dòng)語(yǔ)態(tài)時(shí),不定式的符號(hào)不能被省略)
被動(dòng)語(yǔ)態(tài)的使用目的主要有以下三點(diǎn):
(1)誰(shuí)做的動(dòng)作不知道
(2)說(shuō)出誰(shuí)做的沒(méi)必要；
(3)動(dòng)作承受者需強(qiáng)調(diào)
所以當(dāng)把述句子變被動(dòng)句時(shí)一般可以不再加上原來(lái)主語(yǔ),如果還想表明謂語(yǔ)動(dòng)作的施動(dòng)者是誰(shuí),那就在句尾加上"by + 動(dòng)作施動(dòng)者"
