anything about his plan for the fu-ture5布置作業(yè)1）預習第26單元；2）完成練習冊中安排的練習。四、難句分析1Lizzy：Yes，there must be over two hundred bere是的，這兒想必有200多份。Lizzy：It must be a“D”想必是字母“D”。must作“想必、準是，一定”解，用來表示對某事確有把握的推論或揣測。雖然句中的must也可用may代替，但must語氣更肯定。例如：The farmers must be very tired；theyve kept sowing all the morning農夫們想必很累了，他們整個上午一直在播種。I always meet him in the streetHe must live quite near here我總在這條街上碰到他，想必他就住在附近。must表示推測常用在肯定句中。在疑問句中用can，否定句中用cant。例如：What do you think this invitation can mean？你認為這份請柬可能意味著什么？She cant be a professorshes so young她不可能是教授她還很年輕。在否定句中，也有用cant表示推測的，意思是“想必不，準是不”。例如：I can hear the Browns phone bell ringing but no one is answering it；They cant be athome我聽到布朗家的電話鈴在響，但是沒有人接，他們想必都不在家。2Dr Baker replied to the invitation，accepting it貝克博士還是答復了請柬，接受了邀請。1）reply可作動詞，也可作名詞。作不及物動詞時，意思是“回答”，可用reply to（sbsth）表示“對作出的回答”；作及物動詞時，是“答到、回答說”的意思，后跟直接引語或賓語從句，不直接跟人或物作賓語。作名詞時，是“回答、答復”之意，后面可跟介詞to的短語。例如：She cried，but didnt reply她哭了，但不回答。Please reply to my question請回答我的問題。He replied that he didnt know the secret他回答說他不知道這個秘密。She didnt lift her head，and made no reply她頭也不抬，又不回答。reply和answer都有“回答”的意思，有時可以通用，但reply比answer正式，指經過思考的答復。二者都可以作及物動詞，answer可直接跟名詞作賓語。例如：Can you answer myquestion？Can you reply to my question？你能回答我的問題嗎？2）accepting it是-ing短語，表示伴隨動作，相當于and accepted it。例如：The boss went to see MrKing，praising him for his excellent work老板去看望了金先生，表揚了他出色的工作。注意：accept和receive的區(qū)別：accept和receive都有“收到”的意思。但receive只表示客觀上“收到某物”，與主觀愿望無關，而accept表示主觀上“樂意接受某物”。例如：He received the gift，but he did not accept it他收到了禮物，但他沒接受。I have received an invitation from JohnShall I accept it or refuse it？我收到了約翰的請柬，我是接受還是拒絕？3Would you mind giving a talk today about DNA？能不能請你今天作一個關于DNA的報告？“Would you mind+doing sth？”是日常交際用語，表示禮貌地提出請求。例如：Would you mind sending him a message for me？請你幫我?guī)€口信給他好嗎？Would you mind fetching me some water，please？勞駕給我打點水好嗎？4Dr Lively was going to talk on that very subject today萊芙利博士今天原先要談的正好是這個題目。介詞on在句中作“關于”（about）解。例如：I want to speak to you on a very serious subject我想跟你談一個非常嚴肅的問題。I cant agree with you on this point關于這一點，我不能同意你的意見。句中的very是形容詞，修飾后面的名詞subject，用來加強語氣，作“正好”解。例如：Thats the very thing I need那正是我需要的東西。She determined to go that very afternoon她決定就在當天下午走。
