section a1.it must be carla’s.它一定是卡拉的。must be“一定是”。情态动词must除表示“必须”外，还表示推断，通常与be连用，意为“一定是，肯定是”。must这种表示推测的用法只用于肯定句中。there must be something wrong with the computer.那台电脑一定是出了什么毛病。注意(1)can't be意为“不可能是”，表示有把握的否定推测。 that man can't be mr. wang.he is ill in hospital. 那个人不可能是王先生，他生病住院了。(2)含有must be的句子变为否定句时，需把must be改为can't be。 we must be wrong.我们一定是搞错了。(改为否定句) we can't be wrong.我们不可能搞错了。中考链接【 山东烟台】39. .—i think the man over there must be bob. -- it _______ be him. he has ______ to australia. a. can’t, gone b. can’t, been c. may not, been d. mustn’t, gone 答案：a 【解析】考查点：情态动词can及现在完成时的用法。此处can’t表示推测语气，意为“不可能”；“have/has gone to+地点”意为“去了某地”，表示不在说话人这儿；“have/has been to +地点”表示“去过某地”，现在已经回来了；mustn’t意为“严禁，不许”，may表示不确定的推测语气。句意为“—我认为那边的男人一定是bob。—不可能是他。他已经去了澳大利亚。”故选a。【•盐城】3. — where's david? — he be in the playground because he is fond of playing basketball. a. will b. may c. can't d. mustn't答案：b考查情态动词表推测。根据第二句意“他......在操场上，因为她喜爱打篮球”可知。【湖北·武汉】 33. - look, sue is over there.
