《Life in the future （Part 4）》
1.過(guò)去分詞作定語(yǔ)
 a.單個(gè)過(guò)去分詞作定語(yǔ)，通常前置a及物動(dòng)詞的過(guò)去分詞，具有被動(dòng)和完成的意義。
a   broken cup
a   wounded soldier
an   unexpected guest
the excited crowd
b.不及物動(dòng)詞的過(guò)去分詞，具有主支力完成意義。
 a grown woman
 A woman who has grown
a  retired officer
c.有時(shí)通過(guò)一個(gè)名詞或數(shù)詞加另一個(gè)名詞的過(guò)去分詞可以構(gòu)成形象的復(fù)合形容詞。
a three-legged table.
a one-eved general
an honest-faced man
2.過(guò)去分詞短語(yǔ)作定語(yǔ)：通常后置，其作用相當(dāng)于賓語(yǔ)從句。
a letter written in pencil
a letter which was written in pencil
the book borrowed by jack
the machines produced last year
過(guò)去分詞作狀語(yǔ)時(shí)，為了更好地表達(dá)意義，有些連詞可以與過(guò)去分詞一起連用：
I went on talking,though continually interrupted by George.
我繼續(xù)講我的，心管一直被喬治打斷。
They would never do this unless compelled.
除非受到強(qiáng)迫，否則他們決不會(huì)做種事。
過(guò)去分詞還可引導(dǎo)一個(gè)狀語(yǔ)從句：
Provided(that)there is no opposition,we shall hold the meeting there.
如果沒(méi)有人反對(duì)，我們將在那里開(kāi)會(huì)。
