It says No smoking.”可知，这里禁止吸烟，因此用mustnt表示禁止做的事情，故选B。32D解析：D【详解】句意：听！汤姆一定是一边做作业一边听音乐。让我们上楼去提醒他把音乐关掉。考查情态动词用法。should应该；could能够，可表示委婉语气或用于过去时中；would将会，将要；must必须，表示推测时，意为“一定”。由答语中的“turn it off”可知，此句是推测汤姆一定是在边听音乐边做作业，故选D。33D解析：D【详解】句意：我们已经讨论过这个计划的每个细节并且把一切都准备好了。但仍然有可能出错。我们仍然要非常细心。考查情态动词。must必须；should应该；would将；may可能。根据此处表示推测，应该用may表示可能性，故选D。34C解析：C【详解】句意：切勿将物体从建筑物中扔出去。从高处坠落时，即使是小物体也可能造成严重伤害或死亡。考查情态动词辨析。must必须；should应该；may可能；need需要。根据“Even a small object.cause serious injuries, or death, when dropped from a great height.”可知，从高空中掉落一个小的物体都有可能造成伤害或死亡，表示可能性用may，故选C。35A解析：A【详解】句意：大部分年轻人喜欢网上购物，因为他们不需要花费大量时间从一家店到另一家店。考查情态动词的用法。neednt不必；cant不能；mustnt禁止；shouldnt不应该。根据句意可知，年轻人喜欢网上购物，是因为他们不必把时间花在来回逛商店上。故选A。36A解析：A【详解】句意：妈妈，为什么我必须一天洗那么多次手？为了你的健康，你越小心越好。考查情态动词。cant不可能；mustnt禁止；may not可能不；neednt不必。cant be+too+形容词，表示越越好，故选A。37C解析：C【详解】句意：我们青少年应该有梦想。有梦想和努力，任何惊人的事都能被创造。考查情态动词。may可能；can能够；should应该；might可能；has to不得不；must必须。第一个空表示“应该”，用should；第二个空表示能力，用can。故选C。38D解析：D【详解】句意：在中国，许多家长抱怨他们的孩子不得不熬夜做家庭作业。别担心。政府已经意识到这个问题。我相信很快就会有好消息。考查情态动词。can能、会；should应当；need需要；must必须、一定；根据空前“Im sure”可推知，应是“there must be，一定有”，表示肯定的推测。故选D。39A解析：A【详解】句意：我真的有必要带着口罩去购物吗？恐怕在公共场合你必须如此。这不仅是保护自己，也是保护他人。考查情态动词。must必须；should应该；can可以；need需要。根据“It is not only to protect yourself but also to protect others.”可知在公共场合必须戴口罩。故选A。40D解析：D【详解】句意：那边的男孩是汤姆吗？他经常穿那样的夹克。那不可能是他。他今天没来上学。考查情态动词。neednt不必；shouldnt不应该；mustnt禁止；cant不可能。根据“He is absent from school today”可知，推测那个男孩一定不是汤姆，否定推测用cant，故选D。41A解析：A【详解】句意：这样一件衣服要70美元！你一定是在开玩笑！我是认真的。这是杭州的丝绸做的。考查情态动词辨析。must一定；need必须；will将；can能够。根据“Seventy dollars for such a dress”可知，70美元竟然买这样一件衣服，认为对方一定是在开玩笑，故选A。42B解析：B【详解】句意： 原谅我，我还没有读完这本书。我可以再借一段时间吗？ 抱歉，你不可以。你必须准时归还。考查情态动词。neednt没有必要；cant不可以、不允许；wont不会；shouldnt不应该。根据“You must return it
