"be+過(guò)去分詞"這個(gè)結(jié)構(gòu)并不都是被動(dòng)語(yǔ)態(tài),也可能是系表結(jié)構(gòu)。被動(dòng)語(yǔ)態(tài)與系表結(jié)構(gòu)主要區(qū)別是:被動(dòng)結(jié)構(gòu)表示一個(gè)動(dòng)作,而系表結(jié)構(gòu)表示主語(yǔ)的特點(diǎn)或所處的狀態(tài),試比較下面的句子:
被動(dòng)結(jié)構(gòu)
The enemy was soon surrounded by us.
系表結(jié)構(gòu)
The house is surrounded by trees.
被動(dòng)結(jié)構(gòu)

系表結(jié)構(gòu)
