26、 of(数千的)，故选 C。4.A。考查形容词比较级。分析句意 “你为什么喜欢住在农村？ ” ， “因为那儿噪音少车也少。 ”第一个空格后的 noise 是不可数名词,第二个空格后的 cars 是可数名词的复数。从选项分7析看, less 是 little 的比较级，fewer 是 few 的比较级，都是“少数的，几乎没有” 的意思，故选 A。5.C。考查非谓语动词。根据 make sb. do sth. 句式，make 后面省略 to 的动词不定式在这里充当宾语补足语。故可排除 A、B 和 D，选 C。6.A。考查副词修饰比较级的用法。分析句子，空格后是比较级形式，由于 very, too,

27、 so不能修饰比较级，much 则可以，表示“更”的意思，故选 A。7.A。考查固定用法。used to “过去常常” ；use 作为动词,意为“使用” 。be used to “习惯于” 。上下句意思:“每个星期日，我姑姑都去爬山。 ” “哦？但是她过去讨厌爬山。 ”故选 A。8.D。考查 keep + n. +adj. 的用法。由句意“你们的教室太脏了，所有人都应该保持教室干净。 ”可知选 D。9.C。考查形容词最高级。分析句子，空格后是 in the city，故应用最高级，由于beautiful 是多音节，其最高级用 the most beautiful,故选 C。10.C。此题意为“

28、蓝鲸是世界上最大、最重的动物，却以海洋中最小的动物为食” 。“以为食”应用 feed on .，而且这是一种习惯表达法，不需要使用过去时，故选C。 真题链接真题链接 1. B。句意：我在找一份送给妈妈的生日礼物，但是我找不到任何合适的东西。本题考查不定代词的用法。something 某物，某事，一般不用于疑问句或否定句中；anything 任何东西，任何事物，用于否定句、疑问句；nothing 没有东西；everything 所有东西，一切。根据题意选 B 项。2. A。句意：请问，这本书我可以借长一点时间吗？很抱歉，你今天必须把它还回来。本题考查情态动词。根据答语 Sorry. 可知今天必须

29、归还，故选 A 项。3. C。句意：雾霾将持续多久？我不知道，还没有要结束的迹象。本题考查特殊疑问副词词组。how soon 多久以后；how far 多远(对空间距离提问)；how long 多久(对时间段提问)；how often 多久一次(对频率提问)。last 持续，通常与 how long 搭配。故C 项。II.II. 完形填空。完形填空。1.B。考查词义区别。much 在这里作代词，充当 do 的宾语。2.C。考查上下文推测。许多年前的计算机既大又贵。and 前是 big，故其后也应用原级。3.D。考查词组固定搭配。由于主语是人,故用 be interested in 对感兴趣。8

30、4.B。考查上下文推测。上文说过去的计算机大且贵, 推测出现在的计算机更小更便宜。故选 B。5.A 。考查词义理解。do difficult work 意为“做困难的工作” 。6.D 。考查词义理解。根据下文表明计算机逐渐变得重要了。故选 D。7.B 。考查介词。in+时间段，表示“在内” ，for+时间段，表示延续的一段时间。根据题意， “一台计算机能在几秒钟内处理成千上万个问题” 。故选 B。8.C。考查动词固定用法。need sth. to do sth. 表示 “需要去做某事” 。9.A。考查词义理解。分析句子意思，计算机的作用还在升级，空格应填名词，use 作名词是“用处”的意思。故

31、选 A。10.C。考查上下文推测。根据上下文“人们需要操作和修理它们” ，表示原因。故选 C。III.III. 阅读理解。阅读理解。A A 篇篇 1.D。从短文第二段开头“birds cannot catch them easily. Why? Because locusts change their colors according to the colors of crops (庄稼)”可知“蝗虫的颜色随庄稼而变化是为了保护它们自己” 。因此选 D。2.C。从文中第二段最后一句“So they have to hide themselves and appear only at night

32、. ”可知答案为 C。3.A 。从文中第三段最后一句“This is because they have the colors much like the trees. ”可知。4.B。从短文第四段第一句“A kind of fish in the sea can send out a kind of very black liquid (液体) when it faces danger.”可知。5.C。从全文看，主要讲动物和害虫以及它们与颜色的关系和作用。答案 C 概括的最为准确。B B 篇篇 6. D。本文主要讲述了扎龙是一个自然保护区，位于中国东北的黑龙江省。它是世界上最重要的湿地之一。

33、故本题答案选 D。7. A。由本词前的 and 可知，其表示的内容应该与“provides food”相关；也就是可以生活和居住的地方，故答案选 A。8. A。由第二段的第三句话 Zhalong Nature Reserve is an important living area for 9the rare red-crowned cranes. 扎龙自然保护区是稀少的丹顶鹤的一个重要的生活区；可知选项 A 是错误的。9. D。由第三段 Some people want to change the wetlands to make more space for farms and buildings. This means that there will be less and less space for wildlife 可知越来越多的鸟类濒临危险是因为他们的生活环境越来越少。10. B。由本文以及最后一段. We hope this information will help them understand and make them actively take action to protect wildlife.可知本文主要目的是让人们学习如何保护野生动物。故答案选 B。
