三、五选五Smoke alarms(报警器)House fires cause many deaths each year and a large number of these fires are unfortunately set by children. 1 Kids must understand that they’d better not play with fire. You should keep matches and lighters out of their reach. 2 The main job of such an alarm is to protect you while you're asleep. You should have a smoke alarm outside each bedroom and on each floor of your home. You ought to have two plans for getting out of your house if there is a fire and practise these plans in the dark with your family.A smoke alarm warns you of the danger. 3 Take action immediately. When you come to a closed door, check it with the back of your hand. If it feels hot, there may be smoke or fire behind the door, so take care. Once you are out of your house, call the fire department from a neighbor's house. If a family member or a pet is caught inside, you shouldn’t go back in. Firemen know how to perform rescues safely. 4 Change the batteries at least once a year. You should use the test button each month to see if the alarm and batteries are still working. A smoke alarm lasts about ten years. You ought to change it even if it seems to be working.About two out of three fire deaths happen in homes with no working smoke alarms. 5_________ A．Most of these deaths can be avoidedB．But when you hear it, you don t have much timeC．A smoke alarm is only good if it's working properlyD．So, it's important to teach them that fire is a tool, not a toyE．A smoke alarm greatly reduces your chances of being hurt in a fire四、选词填空move; happy; invent; draw; until; dangerous; build; in; tired; because; country; usefulThe bicycle is one of the simplest but 1 inventions in the world. What is the most surprising is that it was not 2 earlier, although the great inventor Leonardo da Vinci had 3 pictures for bicycles, flying machines and some other things. Those things were not produced 4 long after he died.A person riding a bicycle uses very little energy to make the bicycle 5 , and there is no pollution at all when you are riding. Even so, in most developed 6 , most people don’t go to work by bicycle. It is not because bicycles are expensive or people feel 7 if they ride to work. It’s because the number of cars on the roads becomes larger. It certainly becomes more 8 to ride a bicycle. As a result, more people put their bicycles away and go to work 9 their cars.And in this way, the situation is made more serious. Perhaps the best way to make riding safer and more popular is to 10 roads only for bicycles.答案及解析一、完形填空【参考答案】1．A 2．C 3．B 4．A 5．B 6．C 7．C 8．A 9．D 10．C【语篇解读】本文主要介绍了手机的发明者Martin Cooper以及他对手机的看法。【详情解析】1．句意：他被称为“手机之父”。called把……称为；improved改善；shouted呼喊；regarded认为。根据“father of the cellphone”，可知Martin Cooper被称为“手机之父”。故选A。2．句意：1973年4月3日，Cooper在纽约用手持电话拨打了第一个公开电话。at在；in在；from来自；with和。根据“the first public call...a handheld telephone”可知，用手持电话打电话，介词用from。故选C。3．句意：他和他的团队在摩托罗拉用5个多月研发出这款手机。accepted接受；developed研发；added增加；shared分享。根据“The inventor of that phone, Martin Cooper”可知，Cooper发明了手机。故选B。4．句意：他们只能用这款手机交谈25分钟。talk交谈；play玩；hold抓住；depend依靠。根据“on it for about 25 minutes”可知，这款手机通话时间只能维持25分钟。故选A。5．句意：Cooper指出，这样的通话时间不是问题，因为这款手机太重了，你无法拿25分钟。useless无用的；heavy重的；weak虚弱的；powerful有力量的。根据“because this phone was so...that you couldn’t hold it up for 25 minutes”可知手机太沉，无法拿25分钟。故选B。6．句意：当时我们还不知道这是历史上的一个重要时刻。embarrassing尴尬的；active积极的；important重要的；awful可怕的。根据“Cooper made the first public call”，可知Cooper用手持电话拨打了第一个电话是历史上的重要时刻。故选C。7．句意：今天，手机可以让我们做很多事情。lets让；makes让；allows允许；agrees同意。allow sb to do sth“允许某人做某事”，故选C。8．句意：Cooper还表达了他的担忧。worry担忧；excitement兴奋；disappointment失望；doubt怀疑。根据“We don’t have any privacy (隐私) anymore”可知，这是Cooper的担忧。故选A。9．句意：Cooper说：“我们不再有隐私，因为一切都被记录在某些地方”。something某事；thing东西；everything一切；nothing没有什么。根据“We don’t have any privacy (隐私) ”可知，一切都被记录下来。故选D。10．句意：然而，他满怀希望地说，手机将继续以能够极大地帮助人类的方式发展。politely有礼貌地；bravely勇敢地；hopeful有希望地；secretly秘密地。根据“cellphones will continue to develop in ways that can greatly help humans.”可知，他对手机的未来充满希望，认为手机能够极大地帮助人类。故选C。二、阅读理解【答案】1．D 2．C 3．B 4．A 5．A【导语】本文介绍了四种发明，详细地介绍了它们的特点。【详解】1．细节理解题。根据“It is just as strong as the traditional ones, but flexible (灵活的) enough to fold almost totally flat.”它和传统的一样坚固，但又足够灵活，可以几乎完全扁平折叠。可知，这种可折叠的自行车头盔足够灵活，几乎可以折叠成平面。 故选D。2．细节理解题。根据“Now, the shoe dream comes true in America.”可知，这种新型的能够自己系鞋带的鞋子在美国已经被成功研发出来了。故选C。3．推理判断题。根据“An alarm clock, called Hello Sense, can improve your sleep. It can control the temperature, light and even air quality in your bedroom to help you have a perfect sleep environment. And it can record your sleep cycles.”可知，这种新型的智能闹钟可以改善你的睡眠；可以控制卧室的温度、光线甚至空气质量，帮助你拥有一个完美的睡眠环境；还可以记录你的睡眠周期。而B选项“控制我们的体重”文中并未提及。故选B。4．细节理解题。根据“The lack (缺乏) of vitamin A can cause blindness and many other illnesses.”可知，缺乏维生素A会导致失明和许多其他的疾病。因此，如果一个孩子视力差，他可能缺乏维生素A。故选A。5．推理判断题。根据“Inventions make the world better, smarter and a little more fun.”结合文章内容，可知本文主要介绍了四种不同的发明创造，因此最可能出现在报纸上。选A。三、五选五【参考答案】1．D 2．E 3．B 4．C 5．A【语篇解读】房屋火灾每年都造成很多人死亡，并且很多火灾都是有儿童引起的，因此有必要教给孩子们不要玩火。为了以防万一，家里可以安装烟雾报警器，它能大大减少火灾中受伤的可能性。这篇短文对使用烟雾报警器给了我们一些建议。【详情解析】1．空前这句话House fires cause many deaths each year and a large number of these fires are unfortunately set by children.提到“很多火灾都是由孩子们引起的”；空格后Kids must understand that they’d better not play with fire提到“孩子们最好不要玩火”，前后为因果关系，因此这里应起到承接上文，并引出文章主题的作用，故应选D，意为“因此教给他们火是工具，而不是玩具是很重要的”。2．下句话The main job of such an alarm is to protect you while you're asleep提到了烟雾报警器的作用，这个空位于该段的第一句话，应该是对整段内容的概括，故应选E，意为“烟雾报警器大大降低了你在火灾中受伤的可能性”。3．根据空格前A smoke alarm warns you of the danger.可知，烟雾报警器可以警告我们有危险；空格后的这句话Take action immediately.要我们马上采取行动，因此当你听到烟雾报警器响的时候，逃离的时间就不多了，故应选B，与空后形成因果关系。4．根据这一段的内容Change the batteries at least once a year. You should use the test button each month to see if the alarm and batteries are still working.可知，这一段中告诉我们要注意更换烟雾报警器的电池，每个月应使用测试按钮，看看报警器和电池是否还在工作。故这一段是想告诉我们烟雾报警器只有在正常工作时才是管用的。故应选C。5．空格前About two out of three fire deaths happen in homes with no working smoke alarms提到，大约有三分之二的火灾死亡事件都是由于没有烟雾报警器，A选项中的these deaths呼应了上句话的内容，故应选A，意为“大多数死亡案例是可以避免的”。【点睛】这篇短文是一篇科普说明文，讲述了烟雾报警器的作用。文章主题明确，结构清晰，比较容易理解。题型是选择适当的句子补充短文，题目中给出了五个句子，要求填到文章中的五个地方，这一题型考查的是学生们的阅读理解能力以及逻辑推理能力。做题时，应先通读短文，了解大意；然后阅读后面的五个句子，弄清楚每句话的意思，然后分析文章上下文的逻辑关系，尤其注意空前后的句子，选择最佳的答案。注意先易后难，容易的题目解决了，剩下的句子少了，解题的难度就降低了。例如第3小题，根据空格前A smoke alarm warns you of the danger.可知，烟雾报警器可以警告我们有危险；空格后的这句话Take action immediately.要我们马上采取行动，因此当你听到烟雾报警器响的时候，逃离的时间就不多了，故应选B，与空后形成因果关系。四、选词填空【参考答案】1．the most useful 2．invented 3．drawn 4．until 53．move 6．countries 7．tired 8．dangerous 9．in 10．build【语篇解读】本文介绍了自行车是世界上最简单但最有用的发明之一。【详情解析】1．句意：自行车是世界上最简单但最有用的发明之一。描述发明，应是有用的发明，useful“有用的”，根据“simplest”可知，此处用形容词的最高级，故填the most useful。2．句意：最令人惊讶的是，虽然伟大的发明家列奥纳多·达·芬奇为自行车、飞行器和其他一些东西画过画，但它并没有更早被发明出来。根据“The bicycle is one of the simplest but...inventions in the world.”可知，此处表示发明它，invent“发明”，主语it与谓语invent之间是被动关系，因此用被动形式。故填invented。3．句意：最令人惊讶的是，虽然伟大的发明家列奥纳多·达·芬奇为自行车、飞行器和其他一些东西画过画，但它并没有更早被发明出来。根据宾语pictures可知，此处表示画画，draw“画”，根据“had”可知，此处用过去完成时。故填drawn。4．句意：这些东西直到他死后很久才被生产出来。not...until...“直到……才……”，故填until。5．句意：一个人骑自行车用很少的能量使自行车移动，当你骑的时候根本没有污染。根据“and there is no pollution at all when you are riding”可知，骑行车时，让自行车移动充，move“移动”，make sb do sth“让某人做某事”，故填move。6．句意：即便如此，在大多数发达国家，大多数人并不骑自行车去上班。developed country“发达国家”，有most修饰，用复数名词，故填countries。7．句意：如果他们骑车去上班，这并不是因为自行车贵，也不是因为人们觉得累。根据“if they ride to work”可知，骑自行车去上班，会让人感到累，tired“累的”，是形容词，作为系动词feel的表语，用形容词。故填tired。8．句意：骑自行车当然变得更危险了。根据“It’s because the number of cars on the roads becomes larger.”可知，道路上的汽车数量多了，骑行车会变得危险，dangerous“危险的”，是形容词，作为系动词become的表语，用形容词，故填dangerous。9．句意：因此，越来越多的人把自行车放在一边，开着汽车去上班。in one’s car“乘车”，故填in。10．句意：也许使骑行更安全、更受欢迎的最好方法是修建自行车专用道路。根据“Perhaps the best way to make riding safer and more popular”可知，让骑行车更安全、更受欢迎的方法，应是为自行车建造专用道路，build“建造”，此处用动词不定式作表语，故填build。
