這兩個(gè)句子都涉及到過(guò)去分詞作后置定語(yǔ)的用法.
bought是buy的過(guò)去分詞,left是leave的過(guò)去分詞.它們都可以作后置定語(yǔ)修飾前面的名詞.
相當(dāng)于一個(gè)定語(yǔ)從句:
The pen bought by her is made in China.
=The pen which was bought by her is made in China.
There are five boys left.=There are five boys who were left.
過(guò)去分詞屬于非謂語(yǔ)動(dòng)詞,因此句中不存在兩個(gè)謂語(yǔ)的說(shuō)法.
又如:a boy called Mike 一個(gè)名叫邁克的男孩
注:he pen 應(yīng)為T(mén)he pen .buy的過(guò)去式和過(guò)去分詞的形式一樣，那怎么分清楚是過(guò)去分詞還是過(guò)去式?。窟€有l(wèi)eave的過(guò)去分詞有留下的意思嗎buy的過(guò)去式和過(guò)去分詞的形式都是bought , 區(qū)分的方法在于:如果bought前有動(dòng)詞be的各種形式或have/has/had時(shí),它就是過(guò)去分詞.因?yàn)閎e+過(guò)分,構(gòu)成被動(dòng)語(yǔ)態(tài); 如: This book was bought by my father .have/has/had+過(guò)分,構(gòu)成完成時(shí)態(tài);如: She had bought some food before leaving .另外就是像問(wèn)題中的句子那樣作后置定語(yǔ)時(shí),它是過(guò)去分詞.leavevt. 有"（數(shù)目相減后）剩余，余下"及"剩下，留下（某人）" 之意.其過(guò)分當(dāng)然也有此意.How many minutes are there left ? There are only two minutes left . 還剩幾分鐘?只剩兩分鐘了.They drove offand only Jim was left to take a taxi.他們開(kāi)車走了,只有吉姆留下來(lái)坐出租車.
