重點(diǎn)詞匯講解
1.catch fire與be on fire
1）catch fire：begin to burn著火；燒著。catch fire有動(dòng)態(tài)含義，揩“開始燃燒”。
例如：
Paper catches fire easily.紙容易著火。
The bed clothes catch fire and the whole house may be burnt down.鋪蓋著火了，整個(gè)房子都可能燒掉。
2）be on fire：be burning著火；失火。 be on fire有靜態(tài)含義，指“燃燒的狀態(tài)”。
例如：
The house was on fire.房子著火了。
She woke up at midnight and found the kitchen on fire.她半夜醒來發(fā)現(xiàn)廚房失火了。
2.die of與die from
1）die of可用來表示“死亡的原因”，經(jīng)常用于害病、饑渴、年老、疾勞等致死的場合。
例如：
die of an illness/a disease; die of hunger; die of thirst; die of a fever; die of old age等等。
2）die from常用于過度飲食eating too much；飲酒過度drinking too much；工作過度overwork等。
但是有語法家認(rèn)為這種區(qū)別實(shí)際上并不存在。他們認(rèn)為，在表示死因（the cause of death）時(shí)，既可以用die of，也可以用die of，但是以die of為多見。
例如：
He died of cancer.他死于癌癥。He died from cancer.他死于癌癥。
3.Every year, tobacco companies must persuade new people to start smoking cigarettes.煙草公司每年都要?jiǎng)裾f一些不吸煙的人開始吸煙。
persuade sb. to do sth.意為“勸說某人做某事”。
I persuaded her to accept the invitation to Wu Dongs birthday party.我勸說她接受參加吳東生日晚會(huì)的邀請。
注意：如果勸說不一定成功，可用詞組try to persuade sb, to do sth.。
I tried to persuade her to go with me, but I failed.我勸她跟我一起去，但我沒成功。
另外，勸說某人不要做某事可用詞組persuade sb. not to do sth. 或 persuade sb. against doing sth.
We persuaded Lin Tao not to smoke. =We persuaded Lin Tao against smoking.我們說服了林濤別吸煙。
4. But in the same year, cigarette smoking cost the government even more money, about 28 billion yuan.但在同一年里，因吸煙而使政府付出了更多的錢，約280億元。
cost在這個(gè)句子中意為“使花費(fèi)”，請注意由它構(gòu)成的兩個(gè)常用詞組
a）（sth.）cost sb.+錢 （某物）花費(fèi)某人多少錢
b）（sth，）cost sb.+其他 使某人失去……
That bike cost me 350 yuan.我花了350元買了那輛自行車。
His careless driving cost him a leg.他的粗心駕駛使他失去了一條腿。
以前學(xué)過的與“花費(fèi)”有關(guān)的結(jié)構(gòu)有：
a) sb. spend + 時(shí)間/錢+on + 名詞 某人花……做……
b) sb. spend + 時(shí)間/錢+ (in) doing sth. 某人花……做……
c)sb. pay + 錢+ for sth. 某人花錢買……
d) It take sb. + 時(shí)間/錢 + to do sth. 某人花時(shí)間/錢做
他每月花50元錢買書可譯為：
He spends 50 yuan on books every month.
He spends 50 yuan (in) buying books every month.
He pays 50 yuan for books every month.
It takes him 50 yuan to buy books every month.
小明每天花兩小時(shí)學(xué)英語可譯為：
Xiao Ming spends 2 hours on English every day.
Xiao Ming spends 2 hours (in) learning English every day.
It takes Xiao Ming 2 hours to learn English every day.
5.Do yon mind if I smoke ? 你介意我抽煙嗎？
1）Do/Would you mind if ...? 常用來表示“請求、許可”的意思。句中的mind作“介意”、“反對”解。注意：如果用Would you mind if . . . ?從句中就要用虛擬語氣。如：
Do you mind if I close the window? 關(guān)上窗戶你介意嗎？
Would you mind if I closed the window? 關(guān)上窗戶你介意嗎？
2）在回答這樣的句子時(shí)要特別注意：若在答語里表示“愿意（不反對）”，應(yīng)說“Certainly not”或“Of course not”。若表示“不愿意（反對）”，應(yīng)說“Im sorry, but...”，習(xí)慣上不用yes來直接回答。
3）在 Do/Would you mind之后還可跟動(dòng)詞-ing形式，在動(dòng)詞-ing之前還可以有人稱代詞賓格或物主代詞，用來請求允許，或請求別人作某事。如：
Would you mind my turning off the TV?我關(guān)上電視你介意嗎？
