      【答案】
      1-5:B C A B C 6-10:A C B A B 11-15:A B A A A 16-20:B B C C B
      【解析】
      1.答案:B
      解析:标志词“nw”提示问句和答句需用现在进行时,结构为“be+动词-ing”。主语yu搭配be动词are,d的-ing形式是ding;主语I搭配be动词am,read的-ing形式是reading。A、C、D选项时态混用或结构错误,故正确答案为B。
      2.答案:C
      解析:主语she是第三人称单数,be动词用is;“be gd at”后接动名词,take的-ing形式是taking。A选项第二空用原形,B选项be动词用are,D选项be动词用am且第二空用原形,均错误,故正确答案为C。
      3.答案:A
      解析:由答句“yu can”可知,问句用情态动词Can提问;结合语境“可以用蜡笔,但不许弄坏”,mustn’t表示“禁止、不许”,can’t表示“不能”,此处需用mustn't强调禁止。B、D选项用Must提问不符合答句,C选项can’t语气不符,故正确答案为A。
      4.答案:B
      解析:标志词“Lk”提示前半句用现在进行时(are giving);“every Saturday”提示后半句用一般现在时,主语they是复数,动词用原形give。A、C、D选项时态混用,故正确答案为B。
      5.答案:C
      解析:感叹句中,hw修饰形容词/副词,what修饰名词短语。此处“well”是副词,需用hw引导,结构为“Hw+副词+主语+谓语!”。A、B选项用what,D选项多了不定冠词a,均错误,故正确答案为C。
      6.答案:A
      解析:“teach sb. nt t d sth.”是固定搭配,意为“教某人不要做某事”,否定词nt需放在t前;结合语境“必须准时”,用must表示“必须”。B选项nt位置错误,C、D选项缺少t,故正确答案为A。
      7.答案:C
      解析:“be gd fr”是固定搭配,意为“对……有益”;“be gd at”表示“擅长”,“be gd with”表示“善于应付”,“be gd t”表示“对……友好”。此处指“吃水果对健康有益”,故正确答案为C。
      8.答案:B
      解析:主语yur dad是第三人称单数,助动词用Des;助动词后接动词原形teach。A选项助动词用d,C选项teach加了s,D选项助动词和动词形式均错误,故正确答案为B。
      9.答案:A
      解析:结合语境“图书馆里必须安静,不许大声说话”,must表示“必须”,mustn’t表示“禁止”;can表示“能”,can’t表示“不能”,语气不符。C、D选项逻辑矛盾,B选项语气过弱,故正确答案为A。
      10.答案:B
      解析:由答句“because he is happy”可知,问句询问“他现在为什么在笑”,需用现在进行时(be+动词-ing)。主语he搭配be动词is,smile的-ing形式是smiling。A选项是一般现在时,C选项用can逻辑不符,D选项be动词后接原形错误,故正确答案为B。
