uniform?”可知，不穿校服的原因是太丑了，用ugly。故选D。 2．B 【详解】句意：山顶的空气很稀薄。 考查介词辨析。of属于；at在；with具有；to到。这里是：固定搭配at the top of意为“在……的顶上”。故选B。 3．C 【详解】句意：奶奶正站在楼梯下面。 考查词汇辨析。last最后的；best最好的；bottom底部，名词；worst最糟糕的。根据题干“Grandma was standing”可推测得知奶奶正站在楼梯下面，固定短语“at the bottom of在……底部”。故选C。 4．B 【详解】句意：——你为什么更喜欢住在农村？——嗯，很安静是优点之一。 考查名词辨析。disadvantages缺点；advantages优点；results结果；effects影响。根据“Why do you prefer to live in the countryside?”可知解释为什么更喜欢农村，要介绍其优点。故选B。 5．C 【详解】句意：这个盒子被用于收集能回收利用的废物，例如塑料瓶和纸。reported报道；repair修理；recycle回收利用；review复习；根据such as plastic bottles and paper.可知塑料瓶和纸是可以回收利用的，故选C。 6．A 【详解】句意：——为什么你不买这辆车呢？——它太贵了。我买不起它。 考查动词辨析。afford买得起，支付得起；receive收到；sell卖；keep保持。根据文中回答“It is too expensive.”可知是买不起，afford符合题意。故选A。 7．D 【详解】句意：你挣钱不容易，所以你应该好好利用。 考查动词辨析。give给；have有；get得到；put放。put...to good use“充分利用，善用”，为固定短语。故选D。 8．B 【详解】句意：那栋公寓楼又旧又危险。应该把它拆除。 考查情态动词的被动语态。句子主语It与谓语动词pull down是被动关系，故本句应用被动语态，被动语态的构成是：be+及物动词的过去分词，pull的过去分词是pulled；should情态动词，后接动词原形。故选B。 9．A
