消防隊(duì)員們終于撲滅了加利福尼亞的一場森林大火。

（1）atlast（終于，到底）表示經(jīng)過一番努力之后。

（2）putout可以表示“撲滅”、“熄滅”、“關(guān)掉”等含義：

Pleaseputthelight/fireout.

請把燈關(guān)掉／把火滅掉。

（3）forest雖然是名詞，但在句中起形容詞的作用，修飾fire。2.Sincethen,theyhavebeentryingtofindouthowthefirebegan.

從那時(shí)起，他們一直試圖找出起火的原因。

sincethen從那時(shí)起，到現(xiàn)在為止findout（經(jīng)過研究、努力等）找出，發(fā)現(xiàn)，查出……我會(huì)試著查出昨天救了我的人的名字。I’lltryandfindoutthenameofthepersonwhosavedmylifeyesterday.3.Forestfiresareoftencausedbybrokenglassorbycigaretteendswhichpeoplecarelesslythrowaway.

森林火災(zāi)時(shí)常由破碎的玻璃或人們隨手扔掉的香煙頭引起。

昨天，消防隊(duì)員仔細(xì)查看了地面，但未能發(fā)現(xiàn)碎玻璃。

然而今天上午，一個(gè)消防隊(duì)員偶然發(fā)現(xiàn)了起火的原因。

Accidentally表示事情出乎意料地發(fā)生，即“意外地、偶然地”

discover含有偶然發(fā)現(xiàn)（某個(gè)已經(jīng)存在的東西）的意思，在discover前面加上accidentally更加強(qiáng)了“偶然性”和“意外性”。

7.henoticedtheremainsofasnakewhichwaswoundroundtheelectricwiresofa16,.000-voltpowerline.

他發(fā)現(xiàn)了纏繞在16，000伏高壓線上的一條死蛇。theremains表示“尸體”、“殘骸”，必須用復(fù)數(shù)形式wound為wind的過去分詞。wind在這里不表示“蜿蜒”，而表示“卷在……上”、“纏繞”，常與around／round連用：

Didyouwindthispieceofwireroundthetree?

是你把這根鐵絲纏在樹上的嗎？

8.Inthisway,hewasabletosolvethemystery.Theexplanationwassimplebutveryunusual.

snatchv.抓

Themansnatchedherpurseandran.那人抓起她的錢包就跑。（強(qiáng)調(diào)動(dòng)作很快很猛）

drop&fall

a.drop表示“使落下、使掉落”，是及物動(dòng)詞,帶賓語：

Hedroppedthebag.

b.fall表示“掉下、跌倒”，是不及物動(dòng)詞，不能帶賓語。

Hefelldownthestairsandbrokehisleg.

10.Thesnakethenwounditselfroundthewires.Whenitdidso,itsentsparksdowntothegroundandtheseimmediatelystartedafire.

于是蛇就纏住了幾根電線。當(dāng)它這樣做時(shí)，把火花送到了地面，這些火花立刻引起了一場大火。

Whenitdidso…當(dāng)它這樣做時(shí)……

so常用于一些動(dòng)詞之后，代指前面提過的某個(gè)動(dòng)作／某件事，以免重復(fù)：
