must be a“D”想必是字母“D”。must作“想必、準(zhǔn)是，一定”解，用來(lái)表示對(duì)某事確有把握的推論或揣測(cè)。雖然句中的must也可用may代替，但must語(yǔ)氣更肯定。例如：The farmers must be very tired；theyve kept sowing all the morning農(nóng)夫們想必很累了，他們整個(gè)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(cè)常用在肯定句中。在疑問(wèn)句中用can，否定句中用cant。例如：What do you think this invitation can mean？你認(rèn)為這份請(qǐng)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(cè)的，意思是“想必不，準(zhǔn)是不”。例如：I can hear the Browns phone bell ringing but no one is answering it；They cant be athome我聽(tīng)到布朗家的電話(huà)鈴在響，但是沒(méi)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(fù)了請(qǐng)柬，接受了邀請(qǐng)。1）reply可作動(dòng)詞，也可作名詞。作不及物動(dòng)詞時(shí)，意思是“回答”，可用reply to（sbsth）表示“對(duì)作出的回答”；作及物動(dòng)詞時(shí)，是“答到、回答說(shuō)”的意思，后跟直接引語(yǔ)或賓語(yǔ)從句，不直接跟人或物作賓語(yǔ)。作名詞時(shí)，是“回答、答復(fù)”之意，后面可跟介詞to的短語(yǔ)。例如：She cried，but didnt reply她哭了，但不回答。Please reply to my question請(qǐng)回答我的問(wèn)題。He replied that he didnt know the secret他回答說(shuō)他不知道這個(gè)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(shí)可以通用，但reply比answer正式，指經(jīng)過(guò)思考的答復(fù)。二者都可以作及物動(dòng)詞，answer可直接跟名詞作賓語(yǔ)。例如：Can you answer myquestion？Can you reply to my question？你能回答我的問(wèn)題嗎？2）accepting it是-ing短語(yǔ)，表示伴隨動(dòng)作，相當(dāng)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?yè)P(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(wú)關(guān)，而accept表示主觀上“樂(lè)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(méi)接受。I have received an invitation from JohnShall I accept it or refuse it？我收到了約翰的請(qǐng)柬，我是接受還是拒絕？3Would you mind giving a talk today about DNA？能不能請(qǐng)你今天作一個(gè)關(guān)于DNA的報(bào)告？“Would you mind+doing sth？”是日常交際用語(yǔ)，表示禮貌地提出請(qǐng)求。例如：Would you mind sending him a message for me？請(qǐng)你幫我?guī)€(gè)口信給他好嗎？Would you mind fetching me some water，please？勞駕給我打點(diǎn)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(gè)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(gè)非常嚴(yán)肅的問(wèn)題。I cant agree with you on this point關(guān)于這一點(diǎn)，我不能同意你的意見(jiàn)。句中的very是形容詞，修飾后面的名詞subject，用來(lái)加強(qiáng)語(yǔ)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(dāng)天下午走。
