4、為“名詞+現(xiàn)在分詞”結構的復合形容詞，在句中作定語修飾food。Keep them fit是“keep + 賓語+賓補”結構，賓補由形容詞fit充當。 復合形容詞的構成英語中常見的復合形容詞的構成形式： 名詞+現(xiàn)在分詞：mouth-watering 令人垂涎的；peace-loving 愛好和平的 數(shù)詞+名詞：first-rate 第一流的；second-hand二手的 形容詞/副詞+現(xiàn)在分詞：good-looking 漂亮的；hard-working 工作努力的；easy-going 隨和的；everlasting 永久的 名/形容詞/副詞+過去分詞：man-made 人造的；ready-m

8、I could see things clearly in the dark. 本句為復合句，wish后接省略了that的賓語從句，從句表示的內容與現(xiàn)在事實相反，故從句使用了虛擬語氣。 wish后的從句中虛擬語氣的用法Wish后接that從句時，從句要用虛擬語氣，其用法如下：虛擬情況從句時態(tài)與現(xiàn)在事實相反一般過去時與過去事實相反過去完成時與將來事實相反would/could/might + 動詞原形I wish I were 10 years younger; then I will do whatever I want to.We wish we had studied harder whe

11、原形”結構 此結構用于強調謂語動詞，即要在動詞原形前加助動詞do,does或did，表示“的確，確實，真的”。 這種強調結構只有一般現(xiàn)在時和一般過去時兩種，且沒有疑問和否定形式。 do/does用于一般現(xiàn)在時，did用于一般過去時；do用于第一、第二人稱和第三人稱復數(shù)，does用于第三人稱單數(shù)，did用于各種人稱。They do work hard at maths.He does like eating noodles.He did have a good time last night.特別提醒：在祈使句中運用“do + 動詞原形”形式，往往不表示命令，而表示強烈的請求，有時表達更加客氣的

12、語氣。Do come on time next time.Do come in and sit down.5. “According to my research, neither your restaurant nor mine offers a balanced diet,” explained Wang Peng.本句是一個簡單句，句中neither.nor.“既不也不”，連接兩個并列成分your restaurant和mine作主語，謂語動詞offers的數(shù)與nor后的成分保持一致。 neither.nor.結構 neither.nor.可連接兩個并列成分，表示完全否定。 如果連接兩個

13、名詞或代詞做主語，則謂語動詞的數(shù)和nor后的主語保持一致。（就近原則）Neither you nor I am going to do it. 如果neither.nor.連接兩個句子，且放在句首，則兩個句子都需要部分倒裝。Neither did I go to watch the football match nor did I care its result.歸納拓展：連接并列的名詞或代詞做主語，謂語動詞的數(shù)遵循就近原則的連詞還有：either. or. 要么要么not only. but (also). 不僅而且not. but. 不是而是or. 或等Not you but I am t

14、o blame for the mistakes.練習：語法填空 Not the teacher but the students _ (be) looking forward to seeing the film. Not only he but also I _ (like) playing football. Neither his parents nor he _ (know) anything about it. Either you or one of your students _ (be) to attend the meeting tomorrow.情態(tài)動詞II1. ough

15、t to / ought not to ought to“應當，應該”，跟should用法基本一致，沒有人稱、數(shù)和時態(tài)的變化。它可以表示： “有責任或義務”做某事，語氣比較強； 推測，意為“應該，應是”，暗含很大的可能性； 表示“建議”或“勸告”。We ought to stop polluting nature.He ought to have written the letter by now.You ought to read this book. Its very good. ought to后跟完成式，肯定句中表示“過去本應該做某事而未做”；否定句中表示“過去本不該做某事卻做了”。Y

16、ou ought to have asked him earlier.You oughtnt to have told her the news, but you did. ought to的否定形式為ought not to或oughtnt to，其一般疑問句形式是將ought置于主語前。You ought not to play tricks on the disabled.- Ought I to leave tomorrow?- Yes, you ought to. ought to用在反義疑問句中時，簡短問句用“oughtnt/shouldnt + 主語”。He ought to b

17、e here, oughtnt/shouldnt he?辨析比較： ought to / should一般來說，兩者可換用，只是ought to的語氣略強。另外，表示出于法令規(guī)則、行為準則、道德責任等客觀情況而“應該”做某事時，一般用ought to，多反映客觀情況；若用should則含有個人意見，偏向強調主觀看法。You are his father. You ought to take care of him.We should be polite to others.2. have to / dont have to have to意為“必須，不得不”，側重指客觀需要，可用于不同時態(tài)。Y

18、ou have to clean the classroom before going home. dont have to表示“不必，沒有必要”，即客觀上沒有必要做某事。You dont have to come with me.辨析比較： have to / must have to強調客觀需要，must則強調主觀看法； have to有時態(tài)、人稱和數(shù)的變化，而must只有一種形式； 二者的否定形式的意義不同：dont have to表示“不必”，相當于dont need to, neednt; mustnt則表示“不允許，禁止”；His mother was ill and he had

19、 to stay there to look after her.I must admit I dont like her.You dont have to go there.You mustnt go there.真題鏈接： You _ buy a gift, but you can if you want to. A. must B. mustnt C. have to D. dont have to The new law states that people _ drive after drinking alcohol. A. wouldnt B. neednt C. wont D.

20、mustnt3. need / neednt need作情態(tài)動詞時，后跟動詞原形，表示“需要，有必要”，無時態(tài)，人稱和數(shù)的變化，常用于否定句、疑問句中，也可用于條件句中。You neednt tell him about the matter this afternoon.Need we buy any new equipment?I wonder whether I need advise him.歸納拓展：need還可作為行為動詞使用，此時有人稱、時態(tài)和數(shù)的變化，后接帶to的動詞不定式，常見的結構有： sb. needs to do sth. 某人需要做某事I need to get up early tomorrow.You dont need to leave at once. sth. nee
