his plan for the fu-ture． 5．布置作業(yè)1）預(yù)習(xí)第26單元；2）完成練習(xí)冊中安排的練習(xí)。 四、難句分析 1．Lizzy：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(zhǔn)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；they’ve kept sowing all the morning．農(nóng)夫們想必很累了，他們整個上午一直在播種。 I always meet him in the street．He 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can’t。例如： What do you think this invitation can mean？你認(rèn)為這份請柬可能意味著什么？ She can’t be a professor—she’s so young．她不可能是教授—她還很年輕。 在否定句中，也有用can’t表示推測的，意思是“想必不，準(zhǔn)是不”。例如： I can hear the Brown’s phone bell ringing but no one is answering it；They can’t 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。 2．Dr Baker replied to the invitation，accepting it．貝克博士還是答復(fù)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（sb．／sth．）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(fù)”之意，后面可跟介詞to的短語。例如： She cried，but didn’t reply．她哭了，但不回答。 Please reply to my question．請回答我的問題。 He replied that he didn’t know the secret．他回答說他不知道這個秘密。 She didn’t 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(jīng)過思考的答復(fù)。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(dāng)于and accepted it。例如： The boss went to see Mr．King，praising him for his excellent work．老板去看望了金先生，表揚(yáng)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(guān)，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 John．Shall I accept it or refuse it？我收到了約翰的請柬，我是接受還是拒絕？ 3．Would you mind giving a talk today about DNA？能不能請你今天作一個關(guān)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(diǎn)水好嗎？ 4．Dr 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(guān)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(yán)肅的問題。 I can’t agree with you on this point．關(guān)于這一點(diǎn)，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(qiáng)語氣，作“正好”解。例如： That’s 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(dāng)天下午走。
