section grammar條件狀語從句；讓步狀語從句思維導圖一、條件狀語從句條件狀語從句是用于表示主句動作發(fā)生的前提或條件的從句。通常由下列從屬連詞和短語來引導：if(如果，假如)，unless(除非)，as(so) long as(只要)，provided/providing(that)(只要)，suppose/supposing(假設)，on condition (that)(如果)，in case(以防)等。well come over to see you on wednesday if we have time.如果有空，我們星期三來看你。you can borrow my car as long as you promise not to drive too fast.你可以借用我的車只要你承諾不開快車。ill let you have the book on condition that you return it to me next week.我可以把書借給你，條件是你下星期得還給我。take an umbrella with you in case there is rain this afternoon.隨身帶著把傘，以防今天下午下雨。溫馨提示(1)在條件狀語從句中，用一般現(xiàn)在時代替一般將來時，一般過去時代替過去將來時。if he arrives tomorrow，i will be waiting for him at the airport.如果他明天到，我將在機場等他。(2)unless引導條件狀語從句時，要注意這個連詞自身在意義上是否定的：unlessif.not.，意為“除非，如果不”。i will not go to their party unless i am invited.(i will not go to their party if i am not invited.)假如他們不邀請我，我不會去參加他們的聚會。二、讓步狀語從句讓步狀語從句表示前后句之間為讓步關系。讓步狀語從句常由以下從屬連詞引導：though，although，as，even if/even though(即使)，疑問詞ever/no matter疑問詞(無論)等。1.though，although，as，while引導的讓步狀語從句這些詞引導讓步狀語從句時，意為“雖然，盡管”，although 較為正式。although/though he failed many times，(still) he kept on trying.盡管失敗了很多次，他還是繼續(xù)嘗試。while i like the color，i dont like the shape.盡管我喜歡它的顏色，但不喜歡它的形狀。溫馨提示(1)though和although引導的讓步狀語從句可放在主句之前，也可放在主句之后，不與but連用，但可與表示轉(zhuǎn)折的yet，still連用。(2)though引導的從句可以倒裝，也可以不倒裝，但as引導的從句一定要倒裝，而although引導的從句不倒裝。倒裝形式為“形容詞/副詞/名詞(不加冠詞)/動詞原形though/as主語謂語”，即將形容詞、副詞、分詞、名詞、動詞原形置于句首。tired as/though he was，he continued working in the field.盡管他很累，他繼續(xù)在田里工作。child as/though he was，he had a good command of english.盡管他是個孩子，但他精通英語。hard as/though i tried to explain，he still didnt understand.盡管我盡力向他解釋，他仍然不懂。try as he might，he couldnt solve the problem.盡管他很努力，但還是無法解決這個問題。(3)though可以當副詞用，但although不可當副詞用。i do have a problem though.不過，我的確有一個問題。(4)while引導讓步狀語從句時，一般位于主句之前。2.even if，even though引導的讓步狀語從句even if，even though引導讓步狀語從句時，意為“即使”。even if/though you fail，you will gain experience.即使你失敗了，你也會得到一些經(jīng)驗的。3.“特殊疑問詞ever”和“no matter特殊疑問詞”引導的讓步狀語從句“no matter疑問詞”或“疑問詞ever”所引導的讓步狀語從句均表示“無論；不管”，可以互換。 no matter what/whatever happened，he would not mind.無論發(fā)生什么，他都不會介意的。your mother will wait for you however/no matter how late it is.不管多晚你媽媽都會等著你。溫馨提示 “no matter疑問詞”結(jié)構(gòu)只能引導讓步狀語從句，而“whatever，whichever，whoever，whomever”還可以引導名詞性從句。 whatever (no matter what) you say，i wont believe you.(whatever 引導讓步狀語從句) ill eat whatever(no matter what) you give me.(whatever引導賓語從句)4.whether.or.引導的讓步狀語從句whether.or.引導讓步狀語從句時，表示“不論是否；不管是還是”之意。 whether you believe it or not，its true.不管你信不信，這是真的。whether the weather is good or bad，they will set off as planned.不管天氣是好還是壞，他們都要按計劃啟程。.單句語法填空1.he will not leave unless it is fine tomorrow.2.young as/though she is，she has travelled to many countries to put on shows.3.he is always on time for school whether it rains or snows.4.if you had come a few minutes earlier，you would have met him.5.though/although he works hard，he makes little progress.6.no matter which dictionary you want to buy，ill pay for it.7.however hard the condition is，you must work hard.8.my grandfather still plays tennis now and then，even_though hes in his nineties.9.one can always manage to do more things，no matter how full ones schedule is in life.10.while/although/though i admit that there are problems，i dont agree that they cannot be solved.單句改錯1.she says that shell have to close the shop if business improves.ifunless2.i will go，if you come with me or stay at home.ifwhether3.would you like to go fishing with me tomorrow?provide that you give
