Wounded soldiers have a better chance of survival if they get help soon after being hurt and are quickly taken to a hospital or clinic. But soldiers who do not have medical training may not know how to help their injured friends. Doctors and engineers have developed what they call an “intelligent backpack”. It has a computer and electronic measuring devices. The backpack also has robotic instruments and medicines ready to be given to the injured troops. About 16 doctors and engineers from the University of Pittsburgh, Carnegie Mellon University and several other places are working on the project. The US. Department of Defense has given money to the project. Ron Poropatich leads the project. He is a retired Army surgeon. He says the backpack will help soldiers care for those who are injured. The devices included in the backpack can monitor a persons heart rate and blood pressure. The robotic instruments can even tell whether the soldier has a collapsed lung. The intelligent backpacks computer can compare information gathered about the injured soldier with thousands of similar cases, and quickly tell the best methods to save the soldiers life. Sometimes, it is not always possible to quickly remove the injured soldier from the battlefield. So, Dr. Poropatich says, the researchers hope to create a backpack that will have devices that can keep a soldier alive for a long time. Dr. Poropatich hopes the backpack and its instruments will be ready for testing on animals in about three years. 语篇解读本文是一篇说明文。文章介绍了研究者发明的一种“智能背包” ，内有电脑、 药物等，可以及时救助伤员。 1What can we learn from the first paragraph?

Theres always a question existing in their mind: why does bedtime always have to arrive so soon to break up whatever fun were having? Most children will ask for extra time. Some may even try to argue with logic(逻辑). After all, arent adults supposed to set a good example for children? If adults stay up later, shouldnt children be allowed to stay up later, either? Unfortunately for children everywhere, that_logic_simply_doesnt_hold_water. In fact, science is fairly on the side of adults. No matter how unfair it seems, children simply need more sleep than adults. Even though sleeping seems to be the most boring and unproductive thing you could be doing, its actually very important to your physical and mental health. In addition to providing energy for your body, sleep helps your brain work at its best, too. Scientists believe that the brain remains active during certain periods of sleep, sorting through and storing information from the day. As a general rule, young children need between 9 and 11 hours of sleep each night. Teenagers usually need between 8 and 10 hours of sleep nightly. But why do kids need that extra sleep? In fact, children are still in the process of growingboth physically and mentallyand that extra sleep is what their bodies need to grow in a healthy way. Once they have stopped growing, they dont need so much sleep. Sleeping less than a regular basis can do harm to your health. In addition to feeling physically tired, you can also feel psychologically (心理上地) tired when you cant get enough sleep. It can lead to an inability to focus and think clearly. Being overly tired can also make relativelyeasy things seem nearly impossible. Whats worse, too little sleep can make you get sick easily. 语篇解读本文是一篇议论文。儿童处于成长阶段，与成人相比，需要更多的睡眠，以 保证他们的身体健康地成长。 5What do we know about kids in Paragraph 1? AThey dislike sleeping.
