Unit 3 Language in use1. while的用法的用法 （1）while用作名詞，意為“一段時間；一會兒”。如： I stayed there for a short while. 我在那兒待了一小會兒。 （2）while用作連詞，有以下幾種含義： 1）意為“當(dāng)時；和同時”，引導(dǎo)時間狀語從句。如： While I was watching TV, the bell rang. 當(dāng)我看電視時，鈴響了。 2）連接兩個并列句子，表示對比關(guān)系。如： He went out for a walk, while I stayed at home. 他出去散步了，而我卻待在家里。 3）while和when都可以引導(dǎo)時間狀語從句，但應(yīng)注意：while引導(dǎo)的從句中謂語動詞必須是延續(xù)性動詞或表示狀態(tài)的詞；而when引導(dǎo)的從句中的謂語動詞既可以是延續(xù)性動詞，也可以是短暫性動詞。當(dāng)時間狀語從句中的謂語動詞是延續(xù)性動詞時，while和when可以互相替換。如： When/While we were talking, the teacher came in.我們正在談話時，老師進來了。（talk是延續(xù)性動詞，when和while可互換） The bus had left when we arrived at the bus stop. 當(dāng)我們到達車站時，公共汽車已經(jīng)開走了。（arrive是短暫性動詞，when和while不可互換） When/While we were having a meeting, our teacher came in. 我們正在開會時，老師走了進來。（have是延續(xù)性動詞，when和while可互換） 4）while引導(dǎo)的時間狀語從句還可以表示某個動作正在進行的同時，另一個動作也在進行之中。如： While the teacher was speaking, the students were listening. 老師講課時，學(xué)生們在聽。 2. if 引導(dǎo)的條件狀語從句（二）引導(dǎo)的條件狀語從句（二） （1）含義：從句表示某種假設(shè)的情況，主句表示此種情況所導(dǎo)致的結(jié)果。 （2）時態(tài)：從句如果用一般現(xiàn)在時，主句的謂語動詞多用一般將來時或“情態(tài)動詞+動詞原形”。如： If you start now, youll finish it before dinner. 如果你現(xiàn)在開始（做家庭作業(yè)），晚飯前就可以做完了。 She may come with us if she arrives in time. 如果她來得及時，就可以和我們一道去。 結(jié)構(gòu)結(jié)構(gòu)用途用途含義含義例句例句if從句+祈使句表達建議如果就If you dont feel well, please go to see the doctor. 如果你覺得不舒服，請去看醫(yī)生吧。if從句+主句表達某種假設(shè)如果就If he doesnt work hard, hell fail his exams. 如果他不努力學(xué)習(xí)，考試就會不及格。 （4）若if引導(dǎo)的條件狀語從句的主語為you，則可轉(zhuǎn)換為“祈使句+and+簡單句”或“祈使句+or+簡單句”結(jié)構(gòu)。如： You can pass the exam if you work hard. =Work hard and youll pass the exam. If you dont put the meat in the fridge, it will go bad. =Put the meat in the fridge, or it will go bad. （5）有時，if引導(dǎo)的條件狀語從句可以與with或without引起的介詞短語互換使用。如： If Linda helps me, I can finish the report soon. =With Lindas help, I can finish the report soon. If theres no water, fish may die. =Fish may die without water.【話題呈現(xiàn)】【話題呈現(xiàn)】 本模塊圍繞“Problems”展開話題，講述了青少年在成長過程中遇到的一些問題，并提出了解決問題的方法，要求學(xué)生能夠向他人描述自己生活中遇到的問題，獲取解決問題的建議，樹立正確的人生觀和價值觀，并能學(xué)會運用if條件句描寫某種假設(shè)情況?！炯丫渌C萃】【佳句薈萃】 I want you to get into the habit of doing your homework as soon as you come home from school. 我想讓你養(yǎng)成一放學(xué)回家就做家庭作業(yè)的習(xí)慣。 If you do all these other things instead of your homework, you wont have time to study. 如果你凈做這些其他的事，而不是做作業(yè)，你就沒有時間學(xué)習(xí)了。 You should consider what the most important thing is. 你應(yīng)該考慮什么事情是最重要的。 Thats a shame! 真遺憾！ If you tell the truth, he wont be angry with you. 如果你說實話，他不會生你氣的。 You spent so much time playing computer games. 你花太多時間玩電腦游戲了。 My father isnt angry with Lucy any more. 我父親不再生露西的氣了。 In my opinion, the Internet is helpful rather than harmful. 在我看來，互聯(lián)網(wǎng)有用而非有害。 Smoking is bad for our health. 吸煙有害健康?！緦懽魅蝿?wù)】【寫作任務(wù)】 下面是大明寫給他朋友Tom的一封信，信中描述了他的煩惱。請你以Tom的身份給他寫一封80詞左右的回信，在信中提出他的問題并給出建議。信的開始和結(jié)尾已給出，不計入總詞數(shù)。Dear Tom, My classmate, Lucy, bought a new pen.
