35、 anotherschool the next school yearSo he just didnt want to say anything about his plan for the fu-ture5布置作业 1）预习第 26 单元；2）完成练习册中安排的练习。四、难句分析1Lizzy：Yes，there must be over two hundred bere是的，这儿想必有 200 多份。Lizzy：It must be a“D”想必是字母“D” 。must 作“想必、准是，一定 ”解，用来表示对某事确有把握的推论或揣测。虽然句中的 must 也可用 may 代替，但 must
36、语气更肯定。例如：The farmers must be very tired；theyve kept sowing all the morning农夫们想必很累了，他们整个上午一直在播种。I always meet him in the streetHe must live quite near here我总在这条街上碰到他，想必他就住在附近。must 表示推测常用在肯定句中。在疑问句中用 can，否定句中用 cant。例如：What do you think this invitation can mean？你认为这份请柬可能意味着什么？She cant be a professorshe
37、s so young她不可能是教授她还很年轻。在否定句中，也有用 cant 表示推测的，意思是“想必不，准是不 ”。例如：I can hear the Browns phone bell ringing but no one is answering it；They cant be athome我听到布朗家的电话铃在响，但是没有人接，他们想必都不在家。2Dr Baker replied to the invitation，accepting it贝克博士还是答复了请柬，接受了邀请。1）reply 可作动词，也可作名词。作不及物动词时，意思是“回答”，可用 reply to（sb sth）表示“
38、对作出的回答”；作及物动词时，是“答到、回答说”的意思，后跟直接引语或宾语从句，不直接跟人或物作宾语。作名词时，是“回答、答复”之意，后面可跟介词 to 的短语。例如：She cried，but didnt reply她哭了，但不回答。Please reply to my question请回答我的问题。He replied that he didnt know the secret他回答说他不知道这个秘密。She didnt lift her head，and made no reply她头也不抬，又不回答。reply 和 answer 都有“回答” 的意思，有时可以通用，但 reply 比
39、 answer 正式，指经过思考的答复。二者都可以作及物动词，answer 可直接跟名词作宾语。例如：Can you answer myquestion？Can you reply to my question？你能回答我的问题吗？2）accepting it 是-ing 短语，表示伴随动作，相当于 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，表扬了他出色的工作。注意：accept 和 receive 的区别：accept 和 receive 都有“收到”
40、 的意思。但 receive 只表示客观上“ 收到某物”，与主观愿望无关，而 accept 表示主观上 “乐意接受某物”。例如：He received the gift，but he did not accept it他收到了礼物，但他没接受。I have received an invitation from JohnShall I accept it or refuse it ？我收到了约翰的请柬，我是接受还是拒绝？3Would you mind giving a talk today about DNA？能不能请你今天作一个关于 DNA的报告？“Would you mind+doing
41、sth？”是日常交际用语，表示礼貌地提出请求。例如：Would you mind sending him a message for me？请你帮我带个口信给他好吗？Would you mind fetching me some water，please？劳驾给我打点水好吗？4Dr Lively was going to talk on that very subject today莱芙利博士今天原先要谈的正好是这个题目。介词 on 在句中作“关于” （about）解。例如：I want to speak to you on a very serious subject我想跟你谈一个非常严肃的问题。I cant agree with you on this point关于这一点，我不能同意你的意见。句中的 very 是形容词，修饰后面的名词 subject，用来加强语气，作“正好” 解。例如：Thats the very thing I need那正是我需要的东西。She determined to go that very afternoon她决定就在当天下午走。
