高一英语第二十五单元 At the Conference
receive作“收到”解，只表示客观上“收到某物”，而accept作“接受”解，表示主观上“乐意接受某物”，如果说：“I received an invitation.”则表示“我接受了邀请”，我准备去。例如：
He received the gift, but he didn’t accept it .他收到了礼物，但是他没有接受。
I have received an invitation from Peter. Shall I accept it or refuse it ?
我收到了皮特的请柬，我是接受还是拒绝呢？
3)reply在句中用作不及物动词，作“回答”解，常用reply to sb/sth，表示“对……作出回答”，作及物动词时，是“答道”，“回答说”的意思，后跟直接引语或宾语从句。作名词时，作“回答”、“回信”、“答复”解，例如：
She cried, but didn’t reply.她哭了，但不回答。
Please reply to my question at once.请立刻回答我的问题。
“Certainly, not ”she replied.“当然不行”她答道。
He replied that he didn’t know the secret.他回答说，他不知道这个秘密。
She didn’t lift her head, and made no reply.她头也不抬，也不回答。
answer和reply都可用作及物动词，作“回答”解，但answer可跟名词作宾语而reply只能跟直接引语或宾语从句，如跟名词，reply后须加to。例如：
Can you answer my question ?你能回答我的问题吗？(也可说Can you reply to my question?)
4.If Dr Baker is in the hall, will he please make himself known to me ?
如果贝克博士在会场的话，请他向我自我介绍一下好吗？
make oneself known to sb. 意思是“向某人作自我介绍”。例如：
They are all my friends. Will you please make yourself known to them ?
他们都是我的朋友。请你向他们自我介绍一下好吗？
5.Would 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 sth.”是一个日常交际用语，表示礼貌地提出请求。例如：

Would you mind fetching me some water, please ?请你给我打点水来好吗？
Would you mind sending him a message for me ?请你帮我带个口信给他好吗？
6.You must be joking !你一定是在开玩笑吧！
must表示推测，作“一定”“想必”解。must后用现在进行时be joking，表示此刻正在进行的动作。例如：

他们在哪儿呢？他们一定是正在操场上踢足球了。
It’s ready seven o’clock. She must be waiting for you in her house now.
已经7点，她肯定是正在家里等你呢。
7.That may be so.这是有可能的。
情态动词“may”在句中作“可能”解，也具有推测的含义，但语气不像must那样肯定。例如：
He may be right.他可能是对的。
They may come here tomorrow.他们明天可能会到这里来。
She may be still waiting for us.她可能还在等我们呢。(比较：She must be still waiting for us.他一定还在等我们。)
8.“There must be some mistake,”said Dr Baker.贝克博士说，“准是出了什么差错了。”
句中some作“某一个”解，常用在单数普通名词前，表示未知的，或说话者不愿特别说明的人、地、物等。例如 www.xuehuiba.com
：
Some man at the door is asking to see you.门口有人要见你。

9.“ENT? What does that stand for ?”asked the organizer.──“Illnesses of the ear, nose and throat…”ENT? 它代表什么？组织者问道。──“代表耳、鼻喉科的疾病……”stand for作“代表”解，本句的完整回答是：“It stands for illness of the ear, nose and throat.”ENT是ear, nose, throat。3个词的第一个字母组成的缩略语，这种省略语不管是一个字母或多个字母，当其作主语时，都作单数看待，谓语动词要用单数。例如：

“37℃”中的C代表什么？──代表摄氏(寒暑表)。
