Step 2:Revision Activity 1: Look at the sentences from the reading passage and answer the questions. Then look for more sentences with modals in the reading passage. (P22) a That is why Letters from Father Christmas could be the perfect book… b .The children must have been very excited as they opened it. c .… they might not receive their presents if they were not good. 1) What do the words in red indicate: an order, a request, ability or possibility? 2)Will the meaning of sentence (a) change if we replace “could” with “must” or “might”? 3) What happens if we change “must” and “might” in sentences (b) and (c) into “could”? Step 3:Grammar learning 情态动词must, can/could, may/might均可表示推测, 它们可以对过去、现在或将来的情况作出语气强弱不同的推测。把握推测语气的特点，选择恰当的情态动词。 1. 情态动词表示推测时的语气： 表示肯定的推测时： 各情态动词语气从弱到强依次为 might → may → could → can → must； 表示否定的推测时： can’t / couldn’t语气较强，意为“不可能”；may not / might not语气较弱，意为“可能不”。 must的否定形式mustn’t不表示否定推测，而是表示“不许可”或“不应该”。 2. 情态动词表示推测时, 在用法上有一些限制: ①must只用于肯定句中，意为“一定，准是”。如:This must be your room. ②could多用于否定句和疑问句中。如： He looks young. He couldn’t be over 50. ③may / mi
