Robots performing tasks according to a predetermined set of instructions are nothing new.But robots able to learn how to cook by watching videos are a completely different approach, which is conducted by a group of researchers at the University of Maryland.
If you have posted a video of your favorite recipe on the popular website YouTube, chances are that it will be used by a robot.University of Maryland's professor Yiannis Aloimonos, leader of the group, said “There exists a large amount of video information on the Internet that our robots can capitalize_on.”
“At present, the videos are fed electronically,”said research scientist Cornelia Fermuller.“Originally, we took our own videos, our cameras looking at us doing the cooking,”she explained.“And, as the robot advances, it reacts to good quality videos.And it will react to even lower quality homemade videos.”
So far, the robot named Julia can make a simple salad by breaking each task into basic parts, such as grasping a spoon, bringing it to the bowl, stirring the salad and observing the results.
But why teach a robot how to understand a video when it can easily follow a fixed program?Aloimonos believes predetermined instructions lack flexibility.He thinks one of the problems is how to make the robot understand and use what it learns during a certain task, the so?called feedback (反馈意见); another is the introduction of language.
“I believe it will take quite some time before the robots are able to understand metaphorical (比喻性的) language,”he added.“But,” he said,“we don't need that to create a new world where the robots will be working for us.”
1.The underlined phrase “capitalize on” in Paragraph 2 probably can be replaced by ________.
A.take hold of B.make use of
C.keep track of D.catch sight of
2.Aloimonos probably agrees that at present the robot ________.
A.can not fully digest what it learns
B.can not make a simple salad
C.can follow home?made videos
D.can understand metaphorical language
3.Robots are taught to understand a video mainly because ________.
A.they can easily follow fixed programs
B.they are smart enough to learn cooking
C.cooking videos are more interesting to watch
D.predetermined instructions are not flexible
4.Which of the following might best serve as the title of the passage?
A.Robots Creating a New World
B.Robots Making Cooking Videos
C.Robots Learning to Cook by Watching Videos
D.Robots Performing Tasks by Following Instructions

If you think that running marathons will help you live a long and healthy life, new research may come as a shock. According to a recent scientific study, people who do a very strenuous workout are as likely to die as people who do no exercise at all.
Scientists in Denmark have been studying over 1,000 joggers and non?joggers for 12 years. The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die. The best speed to jog at was found to be about 5 miles per hour. The research suggests that people who jog more than three times a week or at higher speeds of over 7 mph die at the same rate as non?joggers. The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries (动脉). Over time, this can cause serious injuries.
Peter Schnohr, a researcher in Copenhagen, said, “If your goal is to decrease risk of death and improve life expectancy, jogging a few times a week at a moderate pace is a good strategy. Anything more is just unnecessary, and it may be harmful.”
The implications of this are that moderate forms of exercise such as tai chi, yoga and brisk walking may be better for us than “iron man” events, triathlons and long?distance running and cycling. According to Jacob Louis Marott, another researcher involved in the study,“You don't actually have to do that much to have a good impact on your health.And perhaps you shouldn't actually do too much.”
1.The underlined word “strenuous” in Paragraph 1 is closest in meaning to “________”.
A.hard B.regular
C.practical D.flexible
2.The author presents some figures in Paragraph 2 to ________.
A.suggest giving up jogging
B.show risks of doing sports
C.provide supportive evidence
D.introduce the research process
3.According to the scientists, why is too much exercise harmful?
A.It may injure the heart and arteries.
B.It can make the body tired out.
C.It will bring much pressure.
D.It consumes too much energy.
4.What can be inferred from the text?
A.Jogging is the best exercise.
B.More exercise means a healthier life.
C.Marathons runners are least likely to die.
D.Proper exercise contributes to good health.

The principles about applying for jobs have altered greatly lately. In the past, people preferred a hand?written application letter. However, nowadays it is becoming more and more common to apply for a job through the Internet. You can find information on the Internet about how to apply for jobs. Information can be found about how to fulfill your application letter, the clothes that you should wear and how to carry out the interview itself.
The importance of body language is often mentioned, but doesn't always get the attention it deserves. After all, before a word has even been spoken, your body language will have already given people their first impression of you. Additionally, your body language will also give out a lot more information. Based on your body language it can be seen if you are self?confident. It can also show if you are a busy or a quiet type and it helps give an impression of whether you are speaking truthfully or not. Body language can show how enthusiastic you are and if you are a nice person, someone who will take his work seriously, but also someone who has a sense of humor and can enjoy a joke from time to time. The members of the application committee will ask you questions, but your answers won't only be oral. The committee will not only pay attention to what you say, but also to how you say it! Body language will determine first if it “clicks”, and sometimes all it takes is just a few seconds. Everybody uses body language, but it takes place mostly at a subconscious (下意识的) level. Using body language appropriately, you can definitely increase your chances of getting a job.
1.What kind of people is the text mainly meant for?
A.Interviewers. B.Job?hunting people.
C.Employers. D.Lay?off workers.
2.We can learn from the first paragraph that________.
A.hand?written letters are not used in finding a job

Three?dimensional printers are fast becoming everyday devices in the United States. Three?D printers are used to make everything from automobile parts to bone replacements for human patients. American research scientists are now working on creating replacements for living tissue.
Researchers at the Medical University of South Carolina have been working on creating and manufacturing living tissue since 2003. This process is called biofabrication (生物制造). It requires special printing equipment and a special kind of ink.
Traditional printers require ink to produce an image or design on a piece of paper. For their three?D printer, the South Carolina researchers prepare complex nutritious solutions they call bio?inks. Bio?inks are made of proteins and glucose (葡萄糖), which normally provides energy for most cells of the body. The researchers also add living cells taken from the animal that will receive the new, printed tissue. The bio?inks are then added to a device that researchers call the Palmetto bio?printer.
Sarah Grace Dennis is one of the researchers at the Medical University of South Carolina. She says new technology, like the Palmetto bio?printer, is a great help to the biofabrication process.
The bio?inks are placed in three dispensers (分配器), containers, inside the printer. Lasers control both the position of the printing surface and the places where the bio?ink is released.
Michael Yost is a leader of the research team. He says the printing process is fully automated — machine?operated. He says that the Palmetto bio?printer makes it possible to create complex tissue types.
The researchers say bio?printing is still experimental. But they hope in a few years they may be able to print tissue to replace damaged human organs.
But there are still some problems which need to be solved. Some scientists worry about how to get blood to the replacement tissue. The flow of blood is important to keep the printed tissue alive.
Michael Yost hopes that more people will believe in the benefits of biofabrication.
“Tissue biofabrication is a reality, and it is a reality now, and if you come here and you get to see it. You will get to see it. You can't touch it, but you will see it and think this is real. And this is really human.”
1.What can we know about the bio?inks?
A.They are the necessities of bio?printing.
B.They only contain proteins and glucose.
C.They can be placed in the traditional printers.
D.They are available in our local drugstores.
2.Which of the following is one of the concerns with biofabrication?
A.Researchers can't find enough living cells of animals to make the bio?inks.
B.The price of the bio?printer is too high and most people can't afford it.
C.Scientists have some difficulty in getting the blood to the replacement tissue.
D.People are worried about the safety of the biofabrication process.
3.According to Michael Yost, we can infer that ________.
A.the Palmetto bio?printer can work without power
B.the Palmetto bio?printer has been used to treat the patients
C.the Palmetto bio?printer can only be found in the United States
D.the Palmetto bio?printer will have a bright future in medical use
4.The passage mainly tells us about ________.
A.the three?D printer and its working principles
B.the bio?inks and their use in bio?printing
C.the spread use of the bio?printer in the USA
D.the growing demand for biofabrication

We all wish we had just a bit more time. Just think what you could do with an extra hour or two each day: you could finally stick to an exercise routine, or spring?clean the house, or write your novel, or learn the guitar and so on.
1. But I can help you find more hours in your day for the things that really matter.
● Get Out of Bed Earlier
If you normally get up at 7:30 am, try getting up at 7:00 am. That half?hour might not sound like much, but it could be time that you use to exercise, to read that book you've been meaning to finish. 2.
● Do the Important Tasks First
Once you get to work, get the important ones done first (not the easy ones, or even the urgent ones). You can afford to spend at least an hour working on big, important tasks rather than on all those little urgent ones.
3. The urgent tasks will still get done, and you won't miss the important ones.
● Reduce Interruptions
If colleagues have a habit of hanging around your desk to chat, or if the phone is constantly ringing, you might find that it takes you half the day to finish a simple task like writing a letter. Constant interruptions don't just eat up time, they also break your concentration.
When you've got a big task to focus on, let your calls go to voicemail. 4._ Wearing headphones makes it less likely that people will try to strike up a conversation.
●5.
A few minutes chatting, browsing the web, and so on, can easily turn into hours of wasted time over the course of a day.
When you're working, work. If your concentration is slipping, take a proper break, go and get a glass of water, or stretch your legs a bit. And if you're facing a difficult task, try breaking it into small steps or stages so that it's easier to deal with.
A.Stay Focused on Your Work.
B.Take Breaks When Necessary.
C.If you have an office door, close it.
D.If you work like this, you'll usually save time.
E.Would you want me to make your day longer?
F.I can't magically make all your days 25 hours long.
G.Or simply to get your day off to a calm and organized start.

A telescope (望远镜), called Gaia, is being designed by astronomers in Europe, and it couldn’t be more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids (小行星) and comets headed for Earth, Gaia will be looking at our entire galaxy (银河系).
Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia’s map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe (观察) about a billion stars and other objects in our galaxy. Each object will be observed about 70 times.
Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle (角度). These two telescopes act like Gaia’s “eyes”. The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views.
Gaia, which is to be sent into space in 2011, will be a powerful telescope. If you were to use it on Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair.
Gaia is one of more than a dozen telescopes being designed by scientists right now. The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe, with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes.
1.How many different angles can Gaia focus at each time?
A. 2 . B. 3. C. 4 . D. 5.
2.The map to be drawn by Gaia ______.
A. can show every building on Earth
B. can show you where your town is
C. will just show the stars around Earth
D. will show where the stars are in our home galaxy
3.What’s Paragraph 4 mainly about?
A. What Gaia will do in space.
B. When Gaia will start to work.
C. How powerful Gaia will be.
D. What Gaia will do to Earth.
4.The underlined sentence in the last paragraph suggests that the next generation of telescopes _______.
A. seem very surprising to scientists
B. will not be put into use in a short time
C. will just look at new things in universe
D. will be more powerful than the old generations
