【解析】【分析】文章大意：文章介绍了电脑的发明时间，以及电脑的用途。

还有电脑对我们生活的影响。

（1）句意：第一台电脑是在1946年制造的。

根据定冠词the，可知应使用序数词first，故答案是first。

（2）句意：它很大，但是工作得很慢。

slow修饰动词worked，应使用副词slowly，故答案是slowly。

（3）句意：但是他们工作的越来越快了。

空缺处指代前文的computers，因此使用they，故答案是they。

（4）句意：现在没有了电脑人们不能生活。

因为电脑在我们日常生活中越来越重要。

所以没有电脑就不能生活，没有without，故答案是without。

（5）句意：但是现在到处都可以发它。

主语it 和find是被动关系，应使用被动语态，含有情态动词的被动语态是：情态动词+be+过去分词，故答案是be found。

（6）句意：我们可以用电脑读书、写信和购物，购物do shopping，固定搭配，故答案是shopping。

（7）句意：他们不知道他们真正的名字。

name名字，可数名词，根据their可知应使用复数形式，故答案是names。

2．阅读下面短文，在空格处填入一个适当的词或使用括号中词语的正确形式填空。

Strangely enough, some inventions are lost ________ people can't imagine their ________ （valuable）. A use may need to be "invented" along with the invention. An example is the fax machine. The technology for faxing ________ （invent）in the 1800s. It took more than one hundred years, however, for the fax to be seen as useful. In 1843 Alexander Bain invented a machine to ________ （electrical）transmit（传输）writing. At first, it was considered ________ （use）since few people thought there was ________ need for transmitting writing over ________ （wire）. Eventually the value of the invention was realized, and it was improved ________ office use. By the 1980s, the fax machine became a piece of standard ________ （equip）in offices. The reason is ________it can very quickly transmit written documents. Who knows how many other inventions just need to be recognized as valuable?
【答案】because；value；was invented；electrically；useless；a/any；wires；for；equipment；that
【解析】【分析】主要讲了一些发明因为人们不能想象它们的价值而失去，列举传真机器的发明来说明这点。

（1）句意：足够奇怪的是，因为人们不能想象它们的价值，所以一些发明消失了。

后句表示原因，所以用because；形容词修物主代词修饰名词，their它们的，形容词修物主代词，所以后面用形容词valuable的名词value，不可数名词，故填because，value。

（2）句意：传真的科技在19世纪被发明。

invent发明，实义动词，主语technology是动作invent的承受者，时态是一般过去时，所以用一般过去时的被动语态，结构是was/were+动词过去分词，主语technology是不可数名词，所以用was，invent的过去分词是invented，故填was invented。

（3）句意：1843年，亚历山大贝恩发明了一种电子传输文字的机器。

electrical电子的，形容词，副词修饰实义动词，transmit传输，实义动词，所以用副词electrically，电子地，故填electrically。

（4）句意：起初，它被认为是无用的，因为很少有人认为有必要通过电线传输文字。

be considere形容词，表示被认为怎么样，固定搭配，根据后文可知传真的作用后来才被认可，所以起初被认为是无用的，use使用，实义动词，其形容词是useless，无用的；原因是很少人认为有必要，few表示否定，所以用a/any；wire，电线，可数名词，前面没有表示单数的a或者one，所以用复数wires，故填useless；a/any；wires。

（5）句意：最终，这项发明的价值得以实现，并被改进为办公用途。

为了办公用途才被
改进，所以用for，为了，故填for。

（6）句意：到了20世纪80年代，传真机已成为办公室的标准设备。

equip，装备，实义动词，形容词修饰名词，standard，标准的，形容词，所以用equip的名词equipment，设备，不可数名词，故填equipment。

（7）句意：原因是它能很快地传送书面文件。

the reason is that...，原因是……，固定搭配，故填that。

【点评】考查语法填空，考查词汇在语篇中的运用能力。

注意理解句意，首先读一遍，然后再逐一作答。

After keeping trying the program for one year, the teachers found that the students ________ took part in the program did much better in reading tests. ________ amazing it is!
【答案】 more interesting；a；began；desks；It；to do；improving；by；who/that；How 【解析】【分析】文章大意：文章介绍了美国的一所学校采取的一种有趣的教学方法来提高学生们的阅读能力，这种方法是边骑车边阅读。

这种方法的使用收到了良好的效果。

（1）句意：使用自行车，阅读课比以前更有趣。

根据than，可知应使用形容词的比较级，interesting的比较级为more interesting，故答案是more interesting。

（2）句意：美国一个学校的老师尝试了这一种方法。

school使用的单数形式，而且并没有特指哪一所学校，因此应使用不定冠词，school是以辅音字母开始，因此应使用不定冠词a，故答案是a。

（3）句意：边阅读边骑自行车的项目开始于五年前。

根据five years ago可知应使用过去时，begin的过去式是began，故答案是began。

（4）句意：作为阅读和骑行计划的一部分，老师将学生的课桌变成了自行车。

一个班里的学生不只有一个，因此课桌也就不止一个，因此应使用复数形式desks，故答案是desks。

固定搭配，it is+形容词+for sb to do，对于某人来说做某事怎样，故答案是it。

做练习是使用自行车的目的，因此应使用动词不定式做目的状语，故答案是to do。

（7）句意：运动自行车不仅有利于学生们的健康，而且能够帮助学生们提高他们的学习效率。

in为介词，介词后的动词使用动名词，故答案是improving。

（8）句意：他们可以通过骑一会自行车来放松。

骑自行车是他们放松的方式，一般使用by来引出方式状语，故答案是by。

（9）句意：老师发现那些参加了该项目的学生在阅读考试的时候做的更好。

本句为定语从句，先行词students属于人，而且在从句中做主语，因此关系代词可以使用who或者that，故答案是who/that。

（10）句意：多么令人惊奇啊！根据标点符号可知该句为感叹句，强调的是形容词amazing，因此应使用how，故答案是How。

【点评】考查单词在语境中的运用，需要根据单词在语境中的词性进行必要的变形，同时熟记固定搭配和基本句型。

（1）句意：几年后，国王病的很严重。

a few一些，后跟可数名词的复数形式，因此使用year的复数，故答案是years。

（2）句意：他仔细考虑了整整一个晚上。

a whole night是时间段，引出时间段的是介词for，故答案是for。

（3）句意：最后，他决定测试一下他的儿子。

decide to do sth.，决定做某事，因此使用动词不定式，故答案是to test。

of是介词，介词后使用宾格人称代词，将they改为them，故答案是them。

（5）句意：但是不应该有空间剩下，不能向任何人请求建议。

本句为there be句式，should是情态动词，情态动词后使用动词原形，故答案是be。

（6）句意：第二天，国王参观了他的大儿子的房间。

本文的基本时态是一般过去时，因此本句为一般过去时，应使用visit的过去式visited，故答案是visited。

国王有两个儿子，分别对两人或者两件事进行描述，应使用短语one…the other…，一个……另一个……，故答案是the。

因为国王有两个儿子，先去的是大儿子的房间，后去的应该是小儿子的房间，大与小是相对的，因此都应使用比较级，故答案是younger。

angry修饰动词shouted，应使用副词形式angrily，故答案是angrily。

（10）句意：智慧比容易得到的答案更重要。

（1）句意：每年，世界各地都有一个节日来庆祝良好健康睡眠的重要性——世界睡眠日。

由前面的定冠词the，可知此处应填入一个名词，important是形容词“重要的”，与其对应的名词是importance“重要”，故答案填importance。

（2）句意：据说每晚8小时的睡眠时间被认为是平均睡眠时间。

由题干可知主语eight hours与动词consider之间存在被动关系，所以应用被动语态，文章时态为一般现在时，时间作主语谓语动词用单数，所以be动词用is，consider的过去分词是considered，故答案填is considered。

（3）句意：然而，去年中国青少年研究中心报道。

由last year可知，动词时态用一般过去时，report的过去式为reported，故答案填reported。

（4）句意：大约五分之四的中学生睡眠不足。

这里考查分数的表达方法，在英语中一般用基数词表示分数的分子，用序数词表示分数的分母；当分子大于1时，分母要用复数形式，所以五分之四的正确书写是four fifths，故答案填fifths。

（5）句意：对于一些学生来说，他们想早点睡觉，但是他们总是担心他们的学业。

keep doing sth.或者keep+形容词，都表示“使…处于某种状态”，worried，是形容词，故答案填worrying/worried。

（6）句意：他们不能很快入睡。

联系上文语境，结合提示词可知此处句意为“他们不能很快入睡。

”“入睡”fall asleep，固定词组，前面有情态动词can't，所以这里用动词原形，故答案填asleep。

（7）句意：为了解决这类问题。

这里应用动词不定式表示目的，故答案填To solve。

（8）句意：科学家建议学生应该少做功课，多睡觉。

根据后面的more time to sleep可知此处应表达的是“作更少的功课”，句中暗含比较级，little的比较级为less，故答案填less。

（9）句意：比如白天小睡20分钟。

such as意思是“比如”，as是介词后接动词ing形式，故答案填taking。

（10）句意：良好的睡眠习惯也很有帮助。

【答案】 it；pieces；quickly；to；sea；large；took；using；Since；cause
【解析】【分析】大意：本文主要介绍了沙子这种常见的景观。

（1）句意：然而，联合国说，沙子并不是无限的，我们有可能会用完它们。

run out of“用完，用尽”的意思。

这里用it来指代上文的沙子（sand是不可数名词）。

故答案为：it。

（2）句意：沙子由非常小的岩石、土壤和矿物质组成。

根据rock, soil and minerals（矿物质）可知，这是几种成分，因此piece用复数pieces。

故答案为：pieces。

（3）句意：但现在我们使用沙子的速度比它形成的速度要快。

根据副词修饰动词可知，此处应用形容词quick的副词形式quickly修饰动词use“使用”。

故答案为：quickly。

（4）句意：据英国广播公司报道，我们每年用大约150亿吨沙子建造房屋、道路和其他东西。

根据固定搭配 use sth. to do sth. 用某物做某物，可知此处用动词不定式to do做目的状语。

故答案为：to。

（5）句意：人们还把沙子放进海里，制造新的岛屿。

由语境和音标[si:]提示可知，填：sea。

故答案为：sea。

（6）句意：例如，棕榈岛由阿拉伯联合酋长国迪拜的三个大型人工岛屿组成的。

由语境和音标[lɑːdʒ]提示可知，填：large，three large man-made islands三个大型的人工岛屿。

故答案为：large。

（7）句意：2010年，他们用9400万立方米的沙子建造。

根据时间状语In 2010可知，本题的时态为一般过去时。

动词take的过去式为took。

故答案为：took。
