meeting.1.句1和句2用了時間狀語從句；句3用了條件狀語從句；句4、句5和句6用了讓步狀語從句。2whenever引導讓步狀語從句時可以用no_matter_when來替代。語法剖析語法點一時間狀語從句常用來引導時間狀語從句的引導詞有：when, as, while, till, until, before, after, since, the moment, as soon as等。1when, while和as引導的時間狀語從句(1)when可表示瞬間時間；與主句中謂語動詞的動作同時發(fā)生，也可有先后。(2)while引導的句子中動詞常為延續(xù)性動詞。(3)as指動作或事件同時發(fā)生；還可說明兩種正在發(fā)展或變化的情況。It was snowing when we got to the airport.我們到達機場時，天正下著雪。Please write while I read.我念的時候，請寫下來。As I get older, I get more optimistic.隨著年齡的增長，我變得更樂觀了。2till/until引導的時間狀語從句主句的謂語動詞如果是延續(xù)性的應用肯定式，意為“一直到”，如果是非延續(xù)性的要用否定式，意為“直到才”。I waited till/until 9：00.我一直等到9點鐘。(wait為延續(xù)性動作)I didnt go to bed until my father came back.直到父親回來我才上床睡覺。(go to bed為非延續(xù)性動作)名師點津在not .until .結構中not until位于句首時主句部分倒裝。在強調句中，強調until引導時間狀語時，常把not提前，構成It isnt/wasnt until .that .。It wasnt until 11：00 pm that he returned home.直到晚上11點他才回家。3before和since引導的時間狀語從句(1)若表達“還未就，不到就，才，趁還沒來得及”時，需用連詞before。He had put the broken vase away before his mother came back.他趁媽媽還沒回來就把打碎的花瓶收拾好了。(2)It will be時間段before sb. do (does)“多久之后才”。It will be 3 days before our manager signs the agreement.要3天后經(jīng)理才簽那份協(xié)議。(3)since從句的謂語動詞一般是非延續(xù)性動詞，主句的謂語動詞是延續(xù)性的或者是表示反復發(fā)生的動作。since從句的時態(tài)通常是一般過去時，主句中的時態(tài)則通常是現(xiàn)在完成時或現(xiàn)在完成進行時。He has written to me frequently since I got sick.自從我病了以后，他經(jīng)常給我寫信。(4)在“It is時間段since從句”句型中，時間的計算一律從since從句的動作完成或狀態(tài)結束時算起。It is half a year since she left our class.她離開我們班有半年了。(5)since 從句的謂語動詞是延續(xù)性動詞時，說明這一動作或狀語的終止，譯為“自從該動作結束以來有時間了?！盜t is three years since he smoked.他戒煙有三年了。4引導時間狀語從句的名詞詞組一些表示時間的名詞詞組，如the moment, each time, every time, the first time, the last time, the next time, the minute, the instant等也可以用來引導時間狀語從句，起連詞的作用。Every time he came, he would bring me good news.他每一次來，都會給我?guī)砗孟?。The first time I went to Mount Tai, I was very happy.第一次去泰山時，我非常高興。5表示“一就”的引導詞as soon as, immediately, directly, instantly, hardly/scarcely . when ., no sooner . than .等連詞引導的從句都表示從句的動作一發(fā)生，主句的動作隨即就發(fā)生，常譯為“一就”。Immediately the bell rang, the boys rushed out.鈴一響，男孩子們就沖出去了。名師點津若把表示否定含義的副詞hardly/no sooner等放在句首，則它們所在的主句要部分倒裝，且主句要用過去完成時態(tài)。Hardly had he arrived when it began to rain.他剛到就開始下雨了。集中演練111.選詞填空He was working at the table when I went in.It

rain.Hardly had we started when it began to rain.The process will be complete in two years.Itll be two years before the process is completed.I didnt recognize her before she took off her cap.I recognized her after she took off her cap.語法點二條件狀語從句條件狀語從句常由if, once, as long as, unless, on condition that, in case等引導。1if和unless是最常用的條件從句連接詞，unless在意義上等于if . not .，并且語氣較強。if可用于虛擬條件句。You will improve your oral English if you keep on practising.如果你堅持練習的話，你將會提高你的英語口語。If I were you, I would give up smoking at once.(虛擬條件句)如果我是你，我會立即戒煙。Youll fail in French unless you work harder.你要是不再加把勁，法語就考不及格了。2其他常見的條件狀語從句的連接詞還有as/so long as (只要), provided/providing (that)(如果), suppose/supposing (假設), on condition (that) (如果), in case (以防)等。 As long as you dont lose heart, you will succeed.只要你不灰心，你就會成功。Providing/Provided (that)he doesnt agree to help us, who should we turn to for help?如果他不同意幫助我們，我們該向誰求助？Supposing/Suppose you promise not to tell anyone else, Ill explain the secret.如果你保證不告訴任何人，我就把這個秘密解釋給你聽。名師點津(1)在條件狀語從句中用一般現(xiàn)在時表示將來。(2)當條件狀語從句的主語和主句主語一致且從句謂語中有be動詞，則可省略從句的主語和be動詞。集中演練221.單句改錯Unless you change your attitude, I will tell you the way to solve the

who等詞引導。1whatever, however和no matter what/how這兩種形式都可引導讓步狀語從句，意義無差別。Whatever (No matter what) happens, we will not change our minds.無論發(fā)生什么事，我們都不會改變想法。However (No matter how) difficult the work is, we will try our best to finish it in time.無論工作多么困難，我們都要盡力及時完成。名師點津“疑問詞ever”除引導讓步狀語從句外，還可引導主語從句和賓語從句。He can tell you whatever you want to know.你想要知道什么他都可以告訴你。2“形容詞/副詞/名詞/動詞/分詞as/though”可引導讓步狀語從句，表示強調。Young as/though he is, he knows a lot about life.盡管他很小，但他對生活懂得挺多。Fail as he did, he would never give up.盡管失敗了，他也決不會放棄。Intelligent student as he is, he doesnt study hard.盡管他是個聰明的學生，但他不努力學習。名師點津(1)as引導讓步狀語從句時，動詞或現(xiàn)在分詞放在句首，謂語要加助動詞do, does, did或will等；作表語的單數(shù)可數(shù)名詞置于句首時，前不加冠詞。(2)although和though不能和but連用，但可以和yet或still連用。3whether引導的讓步狀語從句Whether you go or not, I will go to visit my teachers.不管你去不去，我都要去看望我的老師。4while也可引導讓步狀語從句，突出對比主句和從句所表示的兩種情況。一般要位于句首。While he is young, he is experienced.他雖然年輕，卻有經(jīng)驗。名師點津當讓步狀語從句的主語和主句主語一致且從句謂語中有be動詞，則可省略從句的主語和be動詞。集中演練331.選詞填空Although he is
