We use “l(fā)earne

2、d” body language when we are introduced to strangers. Now tick the true statements.The sentences from the passage. 我的疑問(wèn)：_課內(nèi)探究質(zhì)疑探究：條件狀語(yǔ)從句條件狀語(yǔ)從句分為真實(shí)條件句和虛擬條件句兩種。假設(shè)的情況有可能發(fā)生的條件句叫真實(shí)條件句；若假設(shè)的情況完全是一種假設(shè)或發(fā)生的可能性不大的條件句叫非真實(shí)條件句。引導(dǎo)條件狀語(yǔ)從句的連詞有：if，unless，so/as long as(只要)，in case(萬(wàn)一的話)，on condition that(假如；在條件下)，suppo

3、se/supposing(that)(假設(shè))，provided/providing(that)(倘若；在條件下)，for fear （that）（以免，唯恐）等。1.If you have finished your homework，you can go out and play._2.Youll fail the exam _(除非你努力學(xué)習(xí))?！咎貏e提示】條件狀語(yǔ)從句中通常不用將來(lái)時(shí)態(tài)，要用一般現(xiàn)在時(shí)或現(xiàn)在完成時(shí)代替一般將來(lái)時(shí)，一般過(guò)去時(shí)或過(guò)去完成時(shí)代替過(guò)去將來(lái)時(shí)。3.只要你不失去信心，你會(huì)成功的。_4._(萬(wàn)一) anything important happens，please ca

4、ll me up.5.如果我父母也被邀請(qǐng)的話，我會(huì)來(lái)。_6.我會(huì)帶著傘，以防下雨。I will take an umbrella _.讓步狀語(yǔ)從句在句子中作讓步狀語(yǔ)的從句叫讓步狀語(yǔ)從句。讓步狀語(yǔ)從句可置于句首，句尾或劇中。引導(dǎo)讓步狀語(yǔ)從句的連詞主要有：although，though，as，even though，even if，whether，whatever，however，no matter+疑問(wèn)詞等。They will stand by you even if you dont succeed._Though/Though he was worn out, (still) he kept

5、 on working._無(wú)論發(fā)生了什么，他都不會(huì)介意的。 _, he would not mind無(wú)論有多晚，他都會(huì)回家。_,he will go home.【特別提示】1.no matter what（who，which，when，etc.）與whatever（whoever，whichever，whenever，etc.）的區(qū)別： 當(dāng)引導(dǎo)讓步狀語(yǔ)從句時(shí)，兩者相同，可以互換，但當(dāng)引導(dǎo)名詞性從（主語(yǔ)從句，賓語(yǔ)從句，表語(yǔ)從句和同位語(yǔ)從句）時(shí)則只能用whatever（whoever，whichever，whenever，etc）。如: I want to marry the man I love

6、, no matter who he may be. = I want to marry the man I love, whoever he may be.(讓步狀語(yǔ)從句)_comes back first is supposed to win the prize.(主語(yǔ)從句) I am ready to do whatever you want me to .（賓語(yǔ)從句） _you did, I will accept.為讓步狀語(yǔ)從句. I will accept _.（無(wú)論你做什么）為賓語(yǔ)從句. 2. as 引導(dǎo)讓步狀語(yǔ)從句的用法 引導(dǎo)讓步狀語(yǔ)從句時(shí)，as意為“雖然，盡管”，通常從句要倒

7、裝，倒裝的方法是將從句的表語(yǔ)或狀語(yǔ)放在as之前.即：adj./adv./n.(不用冠詞)/v.(原形)+as+主語(yǔ)+其他。_(盡管外面正在下大雨), they started out very early. 雖然他很小，但是他知道的很多。_她雖然是名工人，但是很努力工作。_Try as he would, he could not lift the rock. _3. although和though不可與but連用，但可與yet，still或nevertheless連用。Although it was raining hard，yet they went on playing football

8、.盡管他看起來(lái)弱，但是很健康。_4.though還可以用作副詞，放在句末。 It was hard work; I enjoyed it, though=It was hard work, but I enjoyed it.那工作很苦，但我喜歡。5.whether.or.可引導(dǎo)讓步狀語(yǔ)從句，意為“不管是還是；不論是否”。Youll have to attend the ceremony whether you are free or busy._6.除以上提到的從句連詞外，表示讓步的介詞短語(yǔ)有despite, in spite of, 后接名詞。Despite all these facts,
