1、，高級中學(xué)入學(xué)考試英語語法復(fù)習(xí)精品課件，-家庭法，家庭法：一，概念：家庭法用于表達(dá)說話者的主觀愿望或虛擬，條件不一定是事實(shí)或與事實(shí)相反。第二，在條件語句中的應(yīng)用：條件語句可以分為兩個茄子類別。一個是實(shí)際的條件語句，一個是不現(xiàn)實(shí)的條件語句。不切實(shí)際的條件語句表示假設(shè)或?qū)嶋H可能性不大的情況，所以使用虛擬語氣。1，實(shí)際條件語句：實(shí)際條件語句用于陳述語氣，可能會發(fā)生假設(shè)情況。其中if代表意義。時態(tài)關(guān)系：句型：條件子句主語通常是現(xiàn)在shall/will動詞原型例如：If he comes，he will bring his violin。典型示例：the volleyball match will be

2、 put off it實(shí)際條件語句的主子句是未來，從屬子句通常是當(dāng)前詩。注：(1)在實(shí)際條件語句中，主句不能用be going to表示未來。shall，will。(錯誤)If you leave now，you are never going to regret it.You will never regret it。(2)表示真理時，主謂動詞不使用shall(威爾)動詞原形，而是直接使用一般現(xiàn)動詞形式。(。2，不切實(shí)際的條件語句：(1)時態(tài)：可以表示科舉、現(xiàn)在和未來的情況。它的基本特征是時態(tài)后退。a .與目前事實(shí)相反的假設(shè)。文章模式：條件式(would)主要是科舉should(would)

3、動詞原型。例如if they were here，they would help you .b .表示與科舉事實(shí)相反的假設(shè)。文章模式：條件子句短語過去完成時，should (would) have科舉分詞If she had worked harder，She would have succeeded . the rice would not have been burnt If yould，if he had come yesterday，I should/would have told him about it。含義：He did not come yesterday So I did n

4、ot tell him about it . if had not been ill and missed many classes，He would have made greater progress。含義：he was ill and missed many lessons，so he did not make greater progress。c .對未來的虛擬表達(dá)：文章模式：條件句主句通用科舉should動詞原型were不定式動詞原型should動詞原型if you succeeded，Everything would be all right . if you should suc

5、ceed Everything，3，混合條件語句If you had asked him yesterday，you would know what to do now。)If it had rained last night(科舉)，it would be very cold today(當(dāng)前)，4，虛擬條件語句的翻轉(zhuǎn)籌碼：如果虛擬條件語句的子句包含were、should或had=if they were here now，they could help us。had you come earlier，You would have met him。=if you had come earli

6、er，you would have met him . should it rain，the crops would be saved。=were it to The crops would be saved。注：在虛擬語氣的從句中，動詞be的科舉時態(tài)總是“were”，不使用was，即在句子中用were代替be。If I were you，I would go to look for him。如果我是你，我就去找他。If he were here，everything would be all right。如果他在這里，一切都會好起來的。典型示例：_ _ _ _ _ _ _ to do the

7、 work，I should do it some other day . a . if were I b . I were c . were I d . was I回答c.但是要注意，在虛擬條件副詞部分，省略連接詞的倒裝形式的句子的開頭不能作為動詞的縮略語來寫。如果我們可以說Were I not to do，Werent I to do。5，特殊的虛擬語氣語：不能說should。(1)在it is demanded/necessary/a pity that結(jié)構(gòu)中，主語的謂語動詞是should動詞原型，should可以省略。文章模式：suggested it is important tha

8、t(should)do a pity，(1) suggested，ordered，proposed，required，demann.the guard at gate insisted that everybody obey the rules。判斷錯誤：(錯誤)you pale face suggests that you(should)be ill。(示例)your pale face suggests that you are ill。(錯誤)Be wrong。(示例)I insisted that you were wrong。(3)剽竊，同位素的應(yīng)用。Suggestion、propo

9、sal、idea、plan、order、advice等名詞后的表語從句、東魏語從句要使用虛擬語氣，即(should)動詞原形。my idea wish that we(should)get more people to attend the conference . I make a proposal that we(should)hold a meeting next week(hold a meeting next week)賓語從句的動詞形式如下。實(shí)態(tài)wish后句動作先于主句動詞動作，現(xiàn)在在過去詩(be的過去形式是were)后句動作和主句動作同時發(fā)生時，在科舉完成時(had科舉分詞)后實(shí)

10、現(xiàn)的可能性不大的愿望以后在would/could動詞原型(例如：i Wish I Were)前實(shí)現(xiàn)。He wished he hadnt said that。他希望他不要說那種話。I wish it would rain tomorrow。希望明天下雨。(2)Wish to do表示法。Wish sb。/sth。to do I wish to see the manager。=I want to see the manager。I wish the manager to be informed at once。(=I want Only if表示“僅”。If only表示“如果不介意的話”。I

11、f only還可以用于陳述語氣。I wake up only if the alarm clock rings。只有鬧鐘響的時候才醒。If only the alarm clock had rung。希望鬧鐘響了。If only he comes early。希望他早點(diǎn)回來。8，It is (high) time that。It is (high) time that后面的子句謂詞動詞應(yīng)該使用過去式或should和動詞原形，但should省略，渡邊杏。it is time that the children went to bed . it is high time that the chil

12、dren should go to bed .9，need“不必做”和“做渡邊杏”。Didnt need to do說：“過去不需要做任何事情，實(shí)際上不做?！盢eednt have done說，過去不必做任何事，但實(shí)際上做了。例如，John went to the station with the car to meet Mary，so she didnt need to walk back home .約翰開車去車站接瑪麗，所以不必步行回家。John went to the station with the car to meet Mary，so she need nt have walked back home .約翰開車去車站接瑪麗，所以不必步行回家。(瑪麗沒有見到約翰的車，而是步行回家。)，典型示例：there was plenty of time.she _ _ _。a . must nt have hurried b . could nt have hurrie
