過(guò)去分詞作表語(yǔ)與被動(dòng)語(yǔ)態(tài)形式相同,但二者是有明顯區(qū)別的.
1.被動(dòng)語(yǔ)態(tài)強(qiáng)調(diào)動(dòng)作,主語(yǔ)是動(dòng)作承受者.過(guò)去分詞作表語(yǔ)說(shuō)明主語(yǔ)的狀態(tài)或特征.如:
1)This novel was written in 1976.(被動(dòng),強(qiáng)調(diào)“寫”的運(yùn)用)
2)This novel is well written.系表,表示特征)
2.被動(dòng)語(yǔ)態(tài)后常接by+執(zhí)行者,表示某人做.而過(guò)去分詞作表語(yǔ)后不接介詞by,但可以接其它的介詞,表示特征.
例如:1)The cup was broken by him.(被動(dòng))
2)The cup is broken.(系表)
3)I am interested in English.(系表)
3.被動(dòng)語(yǔ)態(tài)可以有許多的時(shí)態(tài)變化,而系表結(jié)構(gòu)沒(méi)有進(jìn)行時(shí)態(tài).如:
