The next time you get caught jumping on your bed you can tell your parents with a straight face that you are not playing, simply getting ready got a promising career in “Mattress Jumping”. Believe it or not, there are some people who actually get paid to do that! According to Reuben Reynoso, a professional mattress tester at San Francisco’s McRoskey Mattress Factory that still makes every mattress by hand, it is real work and needs some training. For a start, it’s not all about jumping to new heights or doing tricks like professional athletes, but rather about feeling each area of the mattress carefully to detect the filling. In order to do it right, every bit of the mattress has to be tested slowly and deliberately.
Over the years, Reynoso has figured out the perfect routine. He begins by placing a protective mat over the mattress so that it doesn’t get dirty or absorb the smell from his feet. Then begins the fun---he steps to the middle of an edge and then takes five steps back and five steps forward. In this way, he slowly but surely, covers the entire surface. The key according to him is to find the perfect number of jumps---Too many and he will end up destroying the mattress completely. Too few And it will not fit into the giant machine for that final sewing! Who knew a job that sounds so simple could have so many skills!
While Reuben will not reveal how he got into this profession, he will admit that it is more fun than being a carpenter, roofer, construction worker and railroad engineer---all jobs he has tried previous to finding his true profession!
1.We learn from the text that the McRoskey Mattress Factory ______.

D. hires athletes as mattress testers
2.The protective mat is used to ______.
A. prevent the tester getting hurt
B. keep the mattress as clean as possible
C. protect the mattress from being destroyed
D. make the mattress fit into the sewing machine
3.According to Reynoso, the most important thing in his work is ______.
A. the timing of his jumps B. the height of his jumps
C. the number of his jumps D. the frequency of his jumps
4.We can learn from the text that Reynoso ______.

The next time you need to get somewhere, you may be able to follow your nose. A study has found that a strong sense of smell is associated with a strong sense of direction.
Researchers conducted an experiment at McGill University in Canada. Fifty-seven adults were invited to participate in a virtual"way-finding task"in which they had to make their way around a virtual environment. They were given 20 minutes to learn about the virtual city. After having passed by each of eight landmarks at least twice, the participants were placed in front of one of the landmarks and asked to find the most direct route to one assigned by the researchers.
The participants also smelled 40 scented(有香气的)pens one at a time. After a brief sniff, the participants chose one word that best identified the smell from four words on a screen.
An additional exercise used a virtual maze(迷宫)to determine if the participants were more likely to rely on landmarks to find the way or if they used a more habit-based method built over time as people travelled the same route over and over again.
What the researchers found was that those with the ability to correctly identify the smells of the pens also had the easiest time performing the way-finding task by way of landmarks. A strong sense of smell was not identified in the participants who used the more habit-based method.
The connection between the sense of smell and way-finding likely came about as a result of the evolution of the nervous system. The original function of the sense of smell in humans may have been intended to support our spatial memory.
Keep that in mind the next time you get lost going to the dentist. It won't prevent you from getting horribly lost, but it's good food for thought along the way.
1.How did the researchers carry out the study?
A.By using typical landmarks in a real city.
B.By combining virtual tests with real-life tests.
C.By testing different senses in a virtual environment.
D.By collecting routine observation data from the participants.
2.What were the participants asked to do after they smelled a scented pen?
A.Decide whether they liked the smell.
B.Use a sentence to describe the smell.
C.Choose a suitable word for the smell.
D.Find the landmark that featured the smell.
3.Which of the following factors is better related to a strong sense of direction according to paragraph 5?
A.The way of using landmarks.
B.More experience in describing things.
C.Quick adjustment to the virtual world.
D.A more habit-based way-finding method.
4.The meaning of the word "spatial" underlined in Paragraph 6 relates to _____.
A.the situation B.the position
C.the spirit D.the time

Don’t get mad the next time you catch your teenager texting when he promises to be studying. He simply may not be able to resist. A University of lowa (UI) study found teenagers are far more sensitive than adults to the immediate effect or reward of their behaviors. The findings may help explain why the initial rush of texting may be more attractive for adolescents than the long-term payoff of studying.
“For the teenager, the rewards are seductive.” says Professor Jatin Vaidya, an author of the study. “They draw adolescents. Sometimes, the rewards are a kind of motivation for them. Even when a behavior is no longer in a teenager’s best interest to continue, they will, because the effect of the reward is still there and lasts much longer in adolescents than in adults.”
For parents, that means limiting distractions so teenagers can make better choices. Take the homework and social media dilemma: At 9 p.m., shut off everything except a computer that has no access to Facebook or Twitter, the researchers advise. “I’m not saying they shouldn’t be allowed access to technology,” Vaidya says “But some help in resetting their concentration is necessary for them so they can develop those impulse-control skills.”
In their study, Vaidya and co-author Shaun Vecera note researchers generally believe teenagers are impulsive(冲动的), make bad decisions, and engage in risky behavior because the frontal lobes(额叶) of their brains are not fully developed. But the UI researchers wondered whether something more fundamental was going on with adolescents to cause behaviors independent of higher-level reasoning.
“We wanted to try to understand the brain’s reward system and how it changes from childhood to adulthood," says Vaidya, who adds that the reward character in the human brain is easier than decision-making. “We’ve been trying to understand the reward process in adolescence and whether there is more to adolescent behavior than an under-developed frontal lobe,” he adds. For their study, the researchers persuaded 40 adolescents, aged 13 and 16, and 40 adults, aged 20 and 35 to participate.
In the future, researchers hope to look into the psychological and neurological(神经学上的)aspects of their results.
1.What does the passage mainly tell us?
A.Always, rewards are attractive to teenagers.
B.Sometimes, adolescents just can’t resist.
C.Resistance can be controlled well by adolescents.
D.Getting rewards is the greatest motivation for adolescents to study.
2.What does the underlined word “seductive” mean?
A.Necessary. B.Attractive.
C.Useful. D.Important.
3.Which statement agrees with Vaidya’s idea?
A.The influence of the reward is weak in adolescents.
B.Parents should help children in making decisions.
C.Children should have access to the Internet.
D.Children need help in refocusing their attention.
4.What result does teenagers’ brain underdevelopment lead to?
A.Doing things after some thought. B.Making good decisions.
C.Joining in dangerous actions. D.Escaping risky behavior.

Just put your special clothes on in the morning and you could jump 3 meters into the air and even carry more than 60 kilograms without getting tired. The walk to school would be very, very easy. Such supercharged clothing is one of the products that could be created using "wearable robotics” technology.
Designed to improve a person's senses and skills, the device could be as simple as a hearing aid. Or it could be a full-body suit that senses what you're going to do, then helps you do it better.
“A superman suit would be the final result in wearable robot i cs ”,s a id Francois Pin, head of robotics and energy systems at the Oak Ridge National Laboratory(橡树林国家实验室), US. While these suits are at least ten years away, in some areas the technology is already in use.
Researchers are developing artificial- arms and legs that allow old,disabled or injured people to move freely. Thus US Army is interested in using wearable robot legs to help soldiers run faster, carry more equipment and be stronger in battle. Jobs that involve lifting heavy loads or saving lives from the rubble of an earthquake could also become much easier.
A robot is a device that responds to a command. You're probably with simple robots, such as toy cars or airplanes that respond to buttons you push on a remote control.
Wearable robotics goes further. Instead of just receiving information through a wire or remotecontrol- the robotic device can send information back to its controller.
Suppose you wore a sleeve that has sensors where your joints are. Every time you move your arm, the sleeve senses your movements and sends the information to a robot, which then moves its arm just as you did. When the robot hits or touches something, it sends a signal back to the sleeve and you sense the action.
In this way,scientists are working to wrap the robot around the person. Their goal is to make the sleeve, shoe or suit help you do what you want to do.
1.Which of the following can replace the underlined word “supercharged” in Paragraph One?
A, expensive B. overcharged C. advanced D. full of electricity
2.Products resulting from this wearable robotics technology do not include _______.
A.remote controls B.hearing aids C.wearable robot legs D.superman suits
3.From the passage, we can infer that________.
A.it will be ten years before robotic devices are in use
B.the wearable robotics technology has been employed in some areas
C.the robots in the robotic devices will do whatever you want to do
D.people must become lazier and less healthier in the future

Whether you prefer burning the midnight oil or going to bed early so you can get up at the break of dawn depends on your genes, according to experts.
I jump out of bed each morning, eager to start an active day. But I can hear my neighbor’s alarm clock ringing non-stop every morning and I doubt he gets to work on time.
A lot of noise comes from his flat in the evening. He’s happy to stay up watching TV till after midnight, while I go to bed early and try to sleep.
Well, it might not be his fault after all. I’m called“a lark (百灵鸟)”and my neighbor“an owl (猫头鹰)”
We all have inside “clocks”in the brain to control all kinds of bodily functions and it is reset every day by light. These inside clocks run to a different schedule in “larks” and “owls”. If you have a fast clock, you like to do things early, and if you have a slow clock, you like to do things late.
Because we live in a 24/7 world, scientists believe it’s important to understand a person’s “chronotype?—the time of the day when they function the best. It could help us lead a healthier life.
A US professor has studied sleeping patterns and thinks work times should be changed and made more individual to fit in with our chronotypes.
And he has advice for those who can’t choose their working hours:“If that’s not possible, we should be more careful about light exposure,” says the professor. “You should try to go to work not in a covered vehicle but on a bike. The minute the sun sets we should use things that have no blue light, like computer. . . screens and other electronic devices.”

You finish a workout and feel great. Then you get up the next morning and your exercised muscles feel sore. You find it hard to lift your arms and brush your teeth, or bend down to pick up a book. What has happened?
Scientists call this soreness 24 to 48 hours after your exercise “delayed onset (延迟发作) of muscle soreness”, or DOMS. It is caused by microscopic damage to muscle fibers, which releases chemicals. The chemicals irritate (刺激) nerve fibers and cause pain.
Muscle soreness is a good sign. It means that you have challenged your muscles and are getting stronger. Everyone experiences it, even the best athletes. But it can be avoided by using the right exercise methods. Here are some tips:
* Warm up before you work out. This is helpful to avoid muscle soreness, but more importantly to avoid injury. It starts circulation to the muscles and warms the muscles and tendons, getting them ready for exercise.
* Stretch after your workout. After exercising, make sure you stretch your muscles for 15 to 20 seconds before they cool down. They will be warm and elastic (弹性的) so they will stretch well.
* Don’t do too much too soon. Whether it’s jogging, running, whatever workout routine you are starting, just do half of the exercise volume the first week to introduce your muscles to the exercises.
If you are already feeling muscles soreness, here are some ways to help relieve it.
* Get a massage (按摩). Lightly massage the sore muscle and gradually increase the depth of the massage. It might be painful in the beginning but it will gradually ease the muscle soreness.
* Take a hot bath. Nothing beats a long soak in a hot bath for muscle soreness. The heat will increase circulation and provide a soothing (舒缓) effect.
* Flush your muscles. Run hot (as hot as you can bear) water over the sore muscles for two minutes and then immediately switch to cold water for 30 seconds. Repeat this process five times. This has the effect of opening and closing your blood vessels (血管). It will flush the acid (酸物质) from them and ease the soreness.
* Exercise gently. Go for a slow walk and breathe deeply. This helps reduce muscle soreness by increasing blood flow to the sore muscles.
