训练2.七选五Imagine that you are in a remote village somewhere with no medical clinic. _1_ Once the doctors get to you, they examine you and take blood samples, but they wont be able to help you until they take the samples back to the hospital to find out what is wrong. _2_ Thanks to engineer Andy Ozcan, many people may never be in this situation. He has invented an app that turns your mobile phone into a diagnostic (诊断的) tool.Ozcans invention is important because it is very accurate and easy to use. In many remote places, even if doctors have microscopes and other instruments to help them make diagnoses, there may still be other problems. Many doctors, for example, dont have enough training to correctly interpret what they see. _3_ With Ozcans mobile phone app, health workers can take a special photo of a blood sample and send it to a central computer at a hospital. The computer will then automatically interpret the photo and send a diagnosis back in a few minutes._4_ His technology only requires a mobile phone and an Internet connection. As more than four billion people already have cell phones, the cost of establishing the diagnostic system is fairly low.By inventing a medical tool that uses existing technologymobile phones, Ozcan has developed a medical tool that is both practical and economical. Therefore, it can be effective almost anywhere. _5_AAnother reason why Ozcans invention is important is that it is inexpensive.BEven though you may only have a simple infection (感染), you might die because of the delay.CPeople are trying to reduce the cost of this new medical tool.DOzcans simple, costeffective tool might just save millions of lives around the world.EThis tool has become much more popular all around the world.FYou become very sick and must wait days until a mobile medical unit arrives to help.GAs a result, they may diagnose illnesses incorrectly.篇章导读：本文是一篇说明文。在偏远地区，医生救助病人比较困难，工程师Andy Ozcan发明的诊断疾病的工具一种手机软件解决了这一难题。该工具仅需手机和网络连接，成本低廉，使用简单。1F根据空格前一句“Imagine that you are in a remote village somewhere with no medical clinic.”并结合常识可知，假如你在一个没有医疗诊所的偏远村庄并且病得很重，你也必须等待数天才能得到帮助，故F项正确。2B根据空格前的内容可知，医生到达后会检查你的身体并采集血样，但是他们无法立即帮助你，直到他们把血样带回医院去检测，这样就延误了疾病的诊治；据此可知，即便你只是患有普通的感染，你也可能会因为延误而死，故B项正确。3G根据空格前的“Many doctors, for example, dont have enough training to correctly interpret what they see.”可知，许多医生因训练有限而无法正确解释他们所看到的病情；因此，他们诊断出的疾病可能会不准确，故G项与此处匹配。4A根据空处所在的位置可知，空处为该段的主题句；由该段内容可知，这种技术只需要手机和互联网连接，且由于已经有超过四十亿人拥有手机，所以建立诊断系统的成本相当低；据此可知，该段主要说明这个发明很重要的另一个原因，即价格低廉，故A项正确。5D根据该段内容尤其是“Therefore, it can be effective almost anywhere.”可知，由于经济实用，这个发明几乎可以在任何地方使用；据此可知，这种简单且合算的产品将可能挽救全世界数百万人的生命，故D项正确。.语法填空In September, in Britain, you may see a lot of swallows. They are gathering together because, very soon, they will be flying south to much _1_ (warm) lands, where they will find plenty of small flying insects on _2_ they feed. There are no such insects about in Britain during the winter, as it is too cold _3_ them.The swallows settle, fly off, dash, and settle again. This they do many times, for they are making short practicing _4_ (flight) in order to be fit for the long journey ahead of them.Flocks of these _5_ (migrate) birds leave Britain in the autumn. They fly _6_ (steady) for hundreds of miles before they reach the warm lands of Africa. But not all the birds get there, for many of them die in the _7_ (storm) weather they meet with on the way.In the spring of the following year they make the long and tiring journey back to Britain. They get _8_ (settle) on the same barn or tree in the same district which they _9_ (leave) the previous autumn.Nobody knows exactly how these birds find their way there and back over such a vast distance, but it has something _10_ (do) with winds and air currents.1_2._3._4._5_6._7._8._9_10._篇章导读：本文是一篇说明文。文章主要介绍了在英国，燕子在秋季迁徙至遥远的暖和的非洲大陆，第二年春天又返回原处的自然现象。1warmer考查形容词的比较级。句意：它们聚集到一起是因为不久之后它们将飞往南方比较温暖的地方。根据语境可知此处应用形容词的比较级。2which考查定语从句的引导词。根据语境及句型结构可知，此处应用on which引导定语从句，which代替上文提到的insects。feed on “以为食”。3for考查介词。句意：因为对它们来说，英国的冬天太冷了。此处用介词for表示“对来说”。4flights考查名词。根据语境可知，此处飞行不止一次，所以名词的复数符合语境。5migrating考查非谓语动词。句意：在秋天的时候，这些成群迁徙的鸟儿离开英国。根据句意可知birds与动词migrate之间为逻辑上的主谓关系，所以用现在分词作定语。6steadily考查词性转换。句意：在到达非洲温暖的地方之前，它们要平稳地飞行数百英里。此处应用副词修饰动词。7stormy考查词性转换。句意：但是并不是所有的鸟儿都会到达那儿，因为途中有许多鸟儿在遇到的暴风雨天气中死去了。根据空格前的the以及空格后的weather可知，此处修饰名词应用形容词。8settled考查形容词。此处get settled意为“定居下来”。9left考查动词的时态。句意：它们在同一地区相同的谷仓或树上定居下来，那是它们前一年秋天离开的地方。根据句意可知，此处“离开”是过去发生的动作，所以用一般过去时。10to do考查固定短语。have something to do with . 意为“与有关”，为固定短语。.短文改错Last week, we have to move away all the books and stationery from the classroom for the first monthly examination.
