【正确答案】 C
【答案解析】[解析] 本题考查形容词最高级。题中有“in the world”出现，所以用最高级。故[C]项正确。
[知识拓展] 当句中有in…或有定语从句…have/has ever done限定，被限定的名词前多用最高级修饰。例：He is the tallest boy in my class. 他是我们班个子最高的男孩子。This is the most beautiful house I have ever seen.这是我见过的最漂亮的房子.
【正确答案】 A
【答案解析】[解析] 本题考查词义辨析及主谓一致。根据上下文分析，该句是问这些鹦鹉长得什么样。like做实意动词，有“喜欢”之意；做介词，be like有“…样子”之意。又因为该句主语是they，所以[A]项正确。
[知识拓展] look like有“长得像…”之意，例：The girl looks like her father.这个女孩长得像她爸爸。
【正确答案】 B
【答案解析】[解析] 本题考查固定搭配。speak有“说…语”之意。故[B]项正确。
[知识拓展] say和talk都有“说，讲”的意思，但say后面可以接间接引语，例：He said that he would go to the party. 他说他会去参加晚会的。talk可用于talk about sth. with sb.，表示与某人谈论某事。
【正确答案】 C
【答案解析】[解析] 本题考查词义辨析。carry有“提；背；搬”之意；move有“移动”之意；take有“带；带走”之意。原文中要表达的意思是宠物店的售货员把顾客带到另一个房子里。故[C]项正确。
[知识拓展] carry的宾语是人的时候，往往是小孩，例：carry the baby抱着小孩儿。move指人的移动时，主语多为人，例：He is moving about in the garden.他在花园里来回走。
【正确答案】 B
【答案解析】[解析] 本题考查人称代词。he为人称代词的主格形式，只能做主语；him为人称代词的宾格形式，只能做宾语；his为物主代词和名词性物主代词，做限定词或表语。故[B]项正确。

【答案解析】[解析] 本题考查疑问词。how much…就价格提问；how many…就可数名词的数量提问；how old…就年龄提问。根据上下文判断，这里是就鹦鹉的价格提问，故[A]项正确。
[知识拓展] 就数量提问的句型：How many…are there…?例：How many people are there in your class?你们班有多少人?就年龄提问的句型：How old is/are…?例：How old is Jack?杰克多大了?

【正确答案】 B
【答案解析】[解析] 本题考查主谓一致。本题的主语是第三人称单数he，谓语动词talk为实义动词，所以一般现在时的否定式应为doesn't。故[B]项正确。
[知识拓展] not…at all有“根本不”之意，例：He doesn't like singing at all.他根本就不喜欢唱歌。
【正确答案】 C
【答案解析】[解析] 本题考查what从句。We don't know that he does语义不完整；We don't know which he does可译为“我们不知道他做的是(这些事中的)哪一件事”，与上下文意思不连贯；We don't know what he does可译为“我们不知道他做了什么”，与上下文意思连贯。故[C]项正确。
[知识拓展] what从句也可做主语，例：What worries me is how to finish so much homework within so short a time.让我担心的是如何在这么短的时间内完成这么多作业。
【正确答案】 A
【答案解析】[解析] 本题考查词义及词性辨析。the other为限定词，有“另外的”之意；the others为代词，有“(已提到过的)其他部分”之意；others为代词，有“其他的人，另外的事”之意。
