参考答案：
1．C
【解析】
句意：从前有一位皇帝，他非常喜欢漂亮的衣服。
考查冠词，第一空表示泛指，且emperor以元音音素开头，故用不定冠词an；指前文提到的人或物用定冠词the，这里指前文提到过的这位皇帝，故选C。
2．A
【解析】
句意：——我觉得我是班上最害羞的。我该怎么办？——在课堂上更加活跃，以便你就可以提高你表达自己的能力。
考查so that引导的目的状语从句。so that以便，引导目的状语从句；unless除非，引导条件状语从句；or或者，表并列；although尽管，引导让步状语从句。分析句子可知，此处表示“在课堂上更加活跃，以便你就可以提高你表达自己的能力”，强调目的，故选A。
3．B
【解析】
句意：Lucy经常使我想起我的好朋友，他们都有长的卷发。thinks of想起；reminds…of使某人想起；helps …out帮助某人摆脱困境；leaves…out遗漏，省去。根据句意They both have long curly hair.可知，Lucy和我最好的朋友很像，所以会使我想起我的朋友，故应选B。A选项think of应连着用，中间不能跟人。
4．C
【解析】
句意：Cathy的嗓音很好，去年她在歌唱比赛中赢得了许多奖项。
考查名词辨析。sound声音，自然界一切声音；idea想法；voice嗓音；time时间。由“… she won many prizes in singing competitions …”可知，Cathy有动听的“嗓音”，故选C。
5．A
【解析】
句意：我敲了门但没人应答。也许他们去听音乐会了。
考查不定代词辨析。nobody没有人；somebody某人；everybody每个人；anybody任何人。根据I knocked at the door“我敲了门”及Maybe they went to the concert“也许他们去听音乐会了”，可知，敲了门但没人应答，所以空格处填nobody。故选A。
6．B
【解析】
句意：勒布朗·詹姆斯是NBA最好的球员之一。他是我的英雄。考查最高级辨析。one of其中之一，用于最高级，可排除AC两项。B. 最好的；D. 最差的。根据He is my hero.可知选B。
7．A
【解析】
句意：就像人类一样，当动物处于危险之中时，他们会尽最大的努力来保护他们的孩子。
考查介词词组辨析。in danger处于危险中；on duty值班；in need需要；on time按时。根据“animals will do their best to protect their young babies”可知，这里说的是“当动物处于危险时”，他们会尽最大努力保护他们的孩子。故选A。
8．A
【解析】
【分析】
句意：——你今晚能和我一起去看电影吗？——抱歉，我需要去为考试做准备。据我所知，汤姆今晚想去看电影。
考查从属连词。As far as就……而言；As long as只要；As soon as一……就……；As often as每当。根据“ I know, Tom wants to see a film tonight”可知，此处使用as far as，as far as I know意为“据我所知”，表示“据我所知，汤姆想看电影”。故选A。
9．D
【解析】
【分析】
句意：我不敢相信他们成功解决了这个问题。
考查动词辨析。included“包括”；got“得到”；woke“唤醒”；succeeded“成功”。根据“in solving”可知，此处是succeed in doing sth.，意为“成功地做了某事”。故选D。
10．D
【解析】
句意：——我尽量让爱丽丝改变她的想法，但是我发现很难。——当我经过的时候，我看见你在做那件事。make sb do sth使某人做某事；see sb do sth看到某人做过某事，已经做完；see sb doing sth看见某人在做某事，还在做；第一空排除AB；第二空排除C，根据题意，故选D。
【点睛】

强调看见时,后面的动作正在进行。
See sb/ sth do
强调看见后面的动作经常发生,或者看见后面的动作的全过程。
