【解析】句意：——杰克，你能帮我倒垃圾吗？——对不起，我不能，妈妈。我现在正在做作业。 考查情态动词及动词时态。句型“could you please…”中could表示委婉语气，所以肯定回答是“Yes, I can”，否定回答是“Sorry, I can’t”。又根据“now”可知，第二空所在句子应为现在进行时“am/is/are+动词现在分词”，主语为I，be动词用am。故选B。 3．B 【解析】句意：——听着！布鲁斯正在班上唱歌吗？——可能是他。但我不确定。 考查情态动词表推测。need需要；could可能；must一定；would愿意，将要。根据“But I’m not sure.”可知，此处说话人不确定是不是布鲁斯。空处应用could表示“可能是他”。故选B。 4．D 【解析】句意：——我能借你的字典吗？——当然你可以。

ago”可知，此处用一般过去时，因此用couldn’t；第二空根据“now”可知，此处用一般现在时，连词but前后表示转折关系，but前表示他不会打篮球，but后表示他打得非常好，因此用情态动词can，故选D。 8．C 【解析】句意：——请不要打开门好吗？我觉得很冷。——好的。但我认为你最好穿上你的外套。 考查动词形式。Could you please (not) do sth.?“请你（不要）做某事好吗”是固定句型，could是情态动词，所以用动词原形；had better do sth.“最好做某事”，后跟动词原形。故选C。 9．C 【解析】句意：——我能借用一下你的英语词典吗？——可以，当然行。 考查情态动词。could可以，能，表示委婉的请求；must必须，一定；can可以，能。问句在请求借东西，需用could表达客气的语气，答句用can表示允许。故选C。
