新概念英语第二册第57课Lesson 57 in the New Concept English Book 2 introduces the use of the modal verb "must" to express logical deduction or certainty.The lesson begins by explaining that 'must' is used when the speaker is certain about something because there is strong evidence or logical reasoning. For example, if we see dark clouds, we might say, "It must rain soon." In this case, we are not guessing; we are certain based on the evidence of dark clouds.The example demonstrates that we use 'must' to talk about the present or future. However, for the past, we use 'must have.' For instance, if we see someone coming in with a wet umbrella, we might remark, "It must have rained." Again, this deduction is based on a certain piece of evidence.The lesson further explains that if we think something is not possible, we use 'can't.' For instance, if we arrive at a bus stop and the bus has already left, we might say, "The bus can't still be here," implying that the bus has already left and it's impossible for it to still be there.The text also provides additional examples using 'must' and 'can't' for different situations. It discusses logical deductions such as a doctor telling a patient that they must rest, a car not starting because the battery is flat, and a small child unable to reach things on a high shelf.In conclusion, Lesson 57 emphasizes the use of 'must' and 'can't' to express logical deductions or certainty in English. These modal verbs are used to convey strong evidence orlogical reasoning regarding a particular situation in the present, future, or past.。
新概念英语第二册第57课:Can I help you, madam?Lesson 57 Can I help you, madam?您要买什么，夫人?First listen and then answer the question.听录音，然后回答以下问题。
Did the woman get what she wanted?A woman in jeans stood at the window of an expensive shop. Though she hesitated for a moment, she finally went in and asked to see a dress that was in the window. The assistant who served her did not like the way she was dressed. Glancing at her scornfully, he told her that the dress was sold. The woman walked out of the shop angrily and decided to punish the assistant next day. She returned to the shop the following morning dressed in a fur coat, with a handbag in one hand and a long umbrella in the other. After seeking out the rude assistant, she asked for the same dress. Not realizing who she was, the assistant was eager to serve her this time. With great difficulty, he climbed into the shop window to get the dress. As soon as she saw it, the woman said she did not like it. She enjoyed herself making the assistant bring almost everything in the window before finally buying the dress she had first asked for.参考译文一位穿着牛仔裤的妇女站在一家高档商店的橱窗前。
