8、, just now, 具體的時間狀語 共同的時間狀語: this morning, tonight,this April, now, once，before, already, recently，lately 現(xiàn)在完成時的時間狀語 for, since, so far, ever, never, just, yet, till / until, up to now, in past years, always, 不確定的時間狀語 3現(xiàn)在完成時可表示持續(xù)到現(xiàn)在的動作或狀態(tài)，動詞一般是延續(xù)性的，如live, teach, learn, work, study, know. 過去時常用的非持續(xù)性動

14、+ 動詞的現(xiàn)在分詞 功用如下： 2 表示一個在過去開始而在最近剛剛結(jié)束的行動，如： Ann is very tired. She has been working hard. Why are you clothes so dirty?

15、has been playing tennis since she was eight. 5 現(xiàn)在完成時強(qiáng)調(diào)動作行為的結(jié)果、影響，而現(xiàn)在完成進(jìn)行時只強(qiáng)調(diào)動作行為本身，如： Toms hands are very dirty. He has been repairing the car. The car is going again now. Tom has repaired it. 注意： 現(xiàn)在完成時有否定結(jié)構(gòu)、而現(xiàn)在完成進(jìn)行時沒有否定結(jié)構(gòu)。 現(xiàn)在完成時態(tài)可表示做完的時期以及已有的經(jīng)驗(yàn)、但現(xiàn)在完成進(jìn)行時不可以 現(xiàn)在完成進(jìn)行時的否定結(jié)構(gòu) 現(xiàn)在完成進(jìn)行時有時也可用否定結(jié)構(gòu)。如： Since tha

17、語從句. 第一部分常規(guī)主語從句，即句子在復(fù)合句中充當(dāng)一個主語 主語從句的時態(tài)：不受主句的時態(tài)影響和限制。 （1）That he finished writing the composition in such a short time surprised us all. （2）Whether we will go for an outing tomorrow remains unknown. （3）Who will be our monitor hasn't been decided yet. （4） Whom we must study for is a question of gr

18、eat importance. （5）What caused the accident remains unknown. （6）Whatever you did is right. （7）Who the watch belongs to was lost is unknown. （8）What we need is time. （9）What we need are good doctors. 小結(jié): （1)引導(dǎo)主語從句連詞有that,whether,who,what,whatever等 （2)連詞位于句首不能省略 （3)主語從句大多數(shù)情況下視為第三人稱單數(shù),但也有例外,如例（9） 第二部分為

19、了防止句子頭重腳輕，通常把形式主語it放在主語位置，真正主語擱置于句末 （1）It is certain that he will win the match. （2）It is true that he has made a very important discovery in chemistry. （3）It is very likely that they will hold a meeting. （4）It is strange that he should do that. （5）It is important that we all should attend the meeti

21、It is known to all that the gun powder was first invented by the Chinese. （11）It is suggested that the work should be done with great care. （12）It seems that he has seen the film.(=He seems to have seen the film) （13）It happened that the two cheats were there. (=The two cheats happened to be there)

22、小結(jié): （1)以that 引出的主語從句,常以形式主語it引導(dǎo). It is +形容詞/名詞/某些動詞ed + that 從句. （2) 在有些that從句中要用虛擬語氣 (should+do/should+have done)例句4,5,6,11. 編輯本段主語從句的用法主語從句與賓語從句兩者的用法和在句中的作用是不同的，下面從它們的各自用法來介紹。 一主語從句 主語從句 定義:在句子中擔(dān)當(dāng)主語的是一個從句,這個從句就叫做主語從句。 主語從句是在復(fù)合句中充當(dāng)主語的從句，通常放在主句謂語動詞之前或由形式主語it代替，而本身放在句子末尾。 1. It 作形式主語和it引導(dǎo)強(qiáng)調(diào)句的比較 主語從句常

23、用it作形式主語，一般常用句型為：It is+名詞/形容詞/過去分詞+主語從句例如： It is still a question whether she will come or not. It is strange that you should like him. It is still unknown which team will win the match. 另外，還有一些比較多見的結(jié)構(gòu)： It turned out that； It has been proved that; It happened/occurred that； It is well-known that等等 而

24、強(qiáng)調(diào)句則不同，它的結(jié)構(gòu)是：It+be+被強(qiáng)調(diào)部分+that+從句 強(qiáng)調(diào)主語：It is the times that produce their heroes.時勢造英雄 強(qiáng)調(diào)賓語：It is English that Prof.Lin teaches us. 強(qiáng)調(diào)狀語：It was in shanghai that I saw the film. 判斷是否是強(qiáng)調(diào)句有一個方法，就是將that以后的“句子的其余部分”拿出來單獨(dú)看，看有沒有缺成分，缺的是什么成分，再把謂語動詞后面that前面的那部分，帶到你認(rèn)為缺成分的地方，如果放進(jìn)去是一句完整的句子了，那就說明是強(qiáng)調(diào)句。 2. 用it 作形式主語

25、的結(jié)構(gòu) (1) It is +名詞+that從句 It is a fact that 事實(shí)是 It is an honor that 非常榮幸 It is common knowledge that 是常識 (2) it is +形容詞+that從句 It is natural that 很自然 It is strange that 奇怪的是 (3) it +不及物動詞+that從句 It seems that 似乎 It happened that 碰巧 (4) it is+過去分詞+that從句 It is reported that 據(jù)報道 It has been proved that

26、 已證實(shí) 3. 主語從句不可位于句首的五種情況 (1) if 引導(dǎo)的主語從句不可居于復(fù)合句句首。 (2) It is said , (reported) 結(jié)構(gòu)中的主語從句不可提前。例如： It is said that President Jingo will visit our school next week. (3) It happens, It occurs 結(jié)構(gòu)中的主語從句不可提前。例如： It occurred to him that he failed in the examination. (4) It doesnt matter how/whether 結(jié)構(gòu)中的主語從句不可提

27、前。例如： It doesnt matter whether he is wrong or not. (5) 含主語從句的復(fù)合句是疑問句時，主語從句不可提前。例如： Is it likely that it will rain in the evening? 4. What 與that 在引導(dǎo)主語從句時的區(qū)別 What 引導(dǎo)主語從句時在從句中充當(dāng)句子成分，如主語賓語表語，而that 則不然。例如： What you said yesterday is right. 二：賓語從句用以區(qū)分主語從句的幾個特征： 1、引導(dǎo)詞：whatwhichwhosewhenwhetherifwhere 2語序：賓

28、語從句必須是用陳述語句。 如：I think that you must work harder. 賓語從句的引導(dǎo)詞、連接詞的區(qū)別、否定轉(zhuǎn)移等現(xiàn)象。 (1)表達(dá)時間的幾個句型：一般用when或者是what time： What time will the train leave? 由于時刻都是固定的，也可以用一般現(xiàn)在時代替一般將來時： What time does the train leave? (2)時間的表達(dá)方式：8：19(nineteen past eight),7:57(three to eight)，在時間的中間也可以加上分的單詞(minutes) (3)had better +動

29、詞原型。意思是提要求，建議。但是上下級不能用這種方式，因?yàn)檎Z氣太重： You had better give up smoking . (4)sb leave sth +地點(diǎn) I left my book in my classroom yesterday. (5)may I have your name(addressage)?一般詢問對方的年齡、名字等，不要習(xí)慣以前的問法，這樣很不禮貌，而是要采訪上面的問法。以前的習(xí)慣是：how old are you? what's your name? (6)修飾名詞的代詞次序：限-描-大-形-年-顏-籍-物-類+名詞： this is a b

30、ridge. This is a beautiful bridge 補(bǔ)充：從句的語序永遠(yuǎn)是陳述句。表語從句就是用一個句子作為表語。說明主語是什么或者怎么樣，由名詞、形容詞或相當(dāng)于名詞或形容詞的詞或短語充當(dāng)，和連系動詞一起構(gòu)成謂語表語從句定義：在一個復(fù)合句中，從句作的是主語的表語成分。 The problem is puzzling. 這個問題令人困惑 主語,連系動詞,形容詞作表語 The problem is when we can get a pay rise. 問題是什么時候我們可以得到加薪. 主語 連系動詞 一個句子作表語-表語從句 連接表語從句的連接詞有：that, what, who

31、, when, where, which, why,whether,how.whoever，whomever，whichever ，whatever等 He has become a teacher. 他已經(jīng)成為一名教師。 He has become what he wanted to be ten years ago. 他已經(jīng)成為了他10年前想成為的。 She has remained there for an hour. 她曾在那里停留了一個小時。 She has remained where I stood yesterday for an hour. 她一直在我昨天站的地方站了一個小時

32、。 His suggestion is good. 他的建議是好的。 His suggestion is that we should stay calm. 他的建議是，我們應(yīng)該保持冷靜。 The question is confusing. 這個問題令人困惑. The question is when he can arrive at the hotel. 問題是，他什么時候可以到達(dá)酒店。 Who will travel with me to Beijing tomorrow.誰與我明天將前往北京。 Why he cried yesterday. 昨天他為什么哭。 How I can per

33、suade her to join us in the party. 我怎么能說服她加入我們的派對。 Whether the enemy is marching towards us. 是否敵人正向我們行進(jìn). 表語從句一定要用陳述語序。 False: The question is when can he arrive at the hotel. Right: The question is when he can arrive at the hotel. 不可以用if，而用whether 連接表語從句(as if 例外）。 引導(dǎo)賓語從句時可以互換if/whether 位于介詞后要用wheth

34、er 位于句首時要用whether 引導(dǎo)表語從句，主語從句，同位語從句時要用whether False: The question is if the enemy is marching towards us. Right: The question is whether the enemy is marching towards us. Right: It looked as if he had understood this question. 不像賓語從句，在有表語從句的復(fù)合句中，主句時態(tài)和從句時態(tài)可以不一致。 Right: The question is who will travel

35、 with me to Beijing tomorrow. Right: The question is why he cried yesterday. that在表語從句中不可以省掉。 編輯本段基本用法表語從句只能置于主句之后，而主句的動詞只能是連系動詞。 名詞性從句在be等系動詞后作表語時被稱為表語從句 例如： The problem is how we can get the things we need.問題是我們怎樣能弄到我們需要的東西。 (how 在表語從句中充當(dāng)方式狀語) The scissors are not what I need. 這把剪刀不是我所需要的。(what 在表

36、語從句中充當(dāng)賓語) What I told him was that I would find him a good play. 我告訴他的是我會給他找個好劇本。(what在主語從句中作直接賓語， that作為表語從句的引導(dǎo)詞在該表語從句中不充當(dāng)句子成分， 不能省略) That is what I want to tell you.那就是我想要對你講的。(what在表語從句中充當(dāng)直接賓語) That is why she failed to pass the exam. 那就是她考試不及格的原因。(why 在表語從句中充當(dāng)原因狀語) “That is why.”是常用句型， 意為“這就是的原因

37、/因此”， 其中why引導(dǎo)的名詞性從句在句中作表語， 該句型通常用于針對前面已經(jīng)說明過的原因進(jìn)行總結(jié)， 又如： That is why you see this old woman before you know, Jeanne. 珍妮， 這就是現(xiàn)在這個老太婆出現(xiàn)在你面前的原因。(前文提到Jeanne對老婦人顯得蒼老憔悴深感詫異， 說話人對她講述了其中的原因之后，用這一句來進(jìn)行概括)。/ That is why I came. 這就是我來的原因。 下面是兩個與“That is why.”形式相似的結(jié)構(gòu)， 它們與“That is why.”結(jié)構(gòu)之間的關(guān)系要能夠辨析清楚： (1)“That is

38、why.”與“That is the reason why.”同義， 只不過從語法結(jié)構(gòu)上講， “That is the reason why.”中why引導(dǎo)的是個定語從句， 將其中的the reason去掉則與“That is why.”結(jié)構(gòu)一樣， 例如： That is (the reason) why I cannot agree. 這就是我不能同意的理由。 (2)“That is because.”句型中從屬連詞because引導(dǎo)的名詞性從句在此作表語， 這也是個常用句型， 意為“這就是為什么/因?yàn)椤薄！癟hat is because.”與“That is why.”之間的不同在于“Th

39、at is because.”指原因或理由， “That is why.”則指由于各種原因所造成的后果， 例如： He did not see the film last night. That is because he had to help his little sister with her homework.昨天晚上他沒有去看電影， 那是因?yàn)樗脦椭拿妹米鲎鳂I(yè)。(第一句話說明結(jié)果， 第二句話說明原因) He had seen the film before. That is why he did not see it last night.他以前曾看過那部電影， 因此他昨天晚上沒

40、有去看。(第一句話說明原因， 第二句話說明結(jié)果) 編輯本段案例分析考題1The traditional view is _ we sleep because our brain is “programmed” to make us do so. (2007上海) A. when B. why C. whether D. that 答案 D 解析 下劃線處之后是包含一個原因狀語從句的表語從句， 如果看不出它是充當(dāng)整個句子結(jié)構(gòu)的表語從句將難以把握整個句子的意思。因此， 應(yīng)選擇可引導(dǎo)名詞性從句且不充當(dāng)任何成分的that。 考題2You are saying that everyone should

Oh, thats _. (2003北京春) A. what makes me feel excited B. whatever I feel excited about C. how I feel about it D. when I

45、feel excited 答案 A 解析 A選項(xiàng)的意思是“令我感覺激動的事物”； B選項(xiàng)的意思是“我覺得激動的任何事物”； C選項(xiàng)的意思是“我對它感覺的方式”； D選項(xiàng)的意思是“令我感覺激動的時間”。四個選項(xiàng)中A最適合跟代表“game”的主語that對應(yīng)， 充當(dāng)表語從句。 編輯本段表語從句與賓語從句的關(guān)系賓語從句和表語從句都屬于名詞性從句。其作用跟名詞在句中的作用相同。故充當(dāng)賓語的句子叫賓語從句，充當(dāng)表語的句子叫表語從句。 賓語從句(1)對于賓語從句要掌握以下三點(diǎn) 語序: 從句的語序必須是陳述句語序, 即“主語 + 謂語”這種形式。 時態(tài): 當(dāng)主句是一般現(xiàn)在時或一般將來時的時候, 從句可以是任
