Lost?in thought, he almost ran into the car in front of him_

意思是：陷入沉思，他幾乎撞到前面的汽車上。

題干中運(yùn)用了短語be lost in迷路，陷入；英語中很多類似的＂be+過去分詞＋介詞／to do/that從句＂的結(jié)構(gòu)都是說明邏輯主語的狀態(tài)，所以只要去掉be動(dòng)詞就可在句中充當(dāng)定語、狀語或補(bǔ)語，因此是用過去分詞做狀語，填Lost。

過去分詞作狀語的用法

過去分詞或過去分詞短語作狀語時(shí)，表示被動(dòng)和完成，在句子中一般可斗態(tài)以作時(shí)間、原因等。

1、時(shí)間狀語

Told that his mother was ill, Li Lei hurried home quickly.李蕾得知母親生旁毀病了時(shí)，馬上趕回了家。

2、原因狀語

Broken down on the high way, his car was carried away by the police.由于他的車在高速公路上壞了，于是被警察拖走了。

3、條件狀語

Given a few minutes, I’ll finish it.再給幾分鐘的時(shí)間，我就會(huì)完成了。

4、讓步狀語

Explained a hundred times, he still can’t understand it.即使給他解釋一百篇，她還是不會(huì)明白運(yùn)銷備。

5、結(jié)果狀語

He fell off a tall tree, his leg broken.他從樹上摔了下來，腿摔斷了。
