Much like a smartphone, your body will go to sleep when there are no new inputs. When you are on a bus, your senses will give you the same repetitive inputs. The streets will flow by, the engine adds constant white noise, you’re seated and not moving, and the smell... well you hope the smell doesn’t change.

Any repetitive input going to your brain will eventually be ignored and your brain will start going into a low energy state. The fact that you fall asleep quickly when closing your eyes on a bus is because you were already on the bus for a while and got used to all the repetitive sensory data.

When you go to bed, you have a lot of new changes. You are lying down, you wear different clothes, you feel the pressure of your covers, you go from bright to dark, noisy to quiet. All of these are new sensory inputs that your brain needs to get used to before going to sleep.

A laboratory experiment to investigate the effects of whole-body vibration (震动) on seated human alertness and sleepiness was carried out. Vibration was applied to the volunteers sitting on the vehicle seat on the vibration platform. Volunteers for this investigation included 18 young male and healthy university students. None of the volunteers had a history of neck pain, diseases of the cervical spine or musculoskeletal disorders. Seated volunteers were exposed to a Gaussian random vibration, with 1–15 Hz frequency bandwidth at 0.2 ms−2 r.m.s., for 20-minutes.

The results suggest that exposure to vibration even for 20-minutes can cause significant sleepiness. The data clearly show that exposure to vibration has considerable influence on subjective sleepiness levels, and more importantly, human reaction times and decrease of attention.

Drowsy driving has been reported to account for approximately 20% of accidents worldwide. In Australia, 16.6% of total road deaths were caused by sleep-related accidents in 1998 alone. It is well established that sleepiness caused by extended hours of driving has considerable influence on driver performance, therefore, compromising transportation safety.

These findings need to be further proved particularly in relation to driving behavior. This line of research can then assist in the development of practical and relevant guidelines for limitation of vibration exposure in the automotive industry, in an effort to reduce the burden of road accidents. That’s something for both car manufacturers and road safety experts to think about.

1.According to the passage, why do we fall asleep quickly on the bus?

A.Because we meet a lot of new changes.

B.Because the surroundings become quiet.

C.Because we get used to the repetitive sensory data.

D.Because our senses give us different kinds of inputs.

2.What is the purpose of the experiment?

A.To investigate people’s sleeping hours and situation.

B.To research whether vibration can affect people’s health.

C.To study the relationship between inputs and people’s attention.

D.To find out how shaking affects people’s sleepiness in the vehicle.

3.What can be inferred from the passage?

A.Sleepy driving is the main cause of road accidents.

B.The research has helped to reduce the burden of road accidents.

C.The findings of the experiment have been recognized by road safety experts.

D.The research results can give some implications to the automobile production.

4.What is the author’s attitude towards the findings?

A.Positive. B.Negative.

C.Disappointed. D.Indifferent.

What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.

Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.

Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic(认错的) about it but instead recognize that you will have a chance of a fresh start at work.

1.What is the passage mainly about?

2.The writer thinks that a student to have a part-time job is probably ___.

3.From the passage we learn that if a student’s school performance is not good, he ___________.

4.From the last paragraph we know one should _________.

Dogs may not know exactly what you are doing especially when you’re trying to figure out a square root or diagram a sentence. But according to a new study, dogs can understand what we’re thinking and feeling by reading our facial expressions and body language and following our eyes.

Researchers studied 29 dogs. The dogs were shown a movie where a woman looked directly at them and said “Hi dog!” Then, the woman looked at a flowerpot sitting next to her. The researchers found that when the woman looked at and spoke directly to a dog, the dog usually followed her eyes to the flowerpot. It proved that the dogs knew that the woman was thinking about the flowerpot.

“By following the eye movements of dogs, we were able to get a first-hand look at how their minds are actually working,” said Jozsef, the senior researcher.

Later in the movie, the woman said “Hi dogs” in a low voice and didn’t look at the dog before looking at the flowerpot. In that situation, the dogs didn’t seem to understand what the woman was thinking. There was no eye contact, and the woman didn’t appear to speak to the dogs directly.

That comes as no surprise to dog trainer Jones. “Dogs normally speak through nonverbal signals. It’s more natural to them,” she said. “If you’ve ever watched dogs at a dog park, you’ve seen it. Within 30 seconds they enter the park, much information has passed between the new dog and the ones already in the park. They’re exchanging looks, observing eyes and body posture. On the other hand, when you speak to a dog, they are learning a foreign language.”

Picking up your nonverbal signals seems more natural. So, if you were hoping that all this means your dog could help you solve your math problems, you’re probably out of luck. But he or she might be a lot more in tune with what you’re thinking than you previously thought.

1.How could the researchers find that the dogs understood the woman’s intention?

2.According to the text, Jones finds that ______.

3.It is implied in the text that dogs can read your emotions only if ______.

4.What does the underlined phrase “be in tune with” in the last paragraph mean?

Try this: For an entire day, forget about the clock. Eat when you’re hungry and sleep when you’re tired. What do you think will happen?

You may be surprised to find that your day is much like most other days. You’ll probably get hungry when you normally eat and tired when you normally sleep. Even though you don’t know what time it is, your body does.These patterns of daily life are called circadian rhythms（生理节奏）, and they are more than just habits. Inside our bodies are several clocklike systems that follow a roughly 24-hour cycle. Throughout the day and night, our inner clocks direct changes in temperature, body chemicals, hunger, sleepiness and more.

Everyone’s rhythms are different, which is why you might like to stay up late while your sister always wants to go to bed early. But on the whole, everyone is programmed to feel tired at night and energetic during the day. Learning about our body clocks may help scientists understand why problems arise when we act out of step with our circadian rhythms. For example, traveling across time zones can make people wake up in the middle of the night. Regularly staying up late can make kids do worse in tests.

“There is a growing sense that when we eat and when we sleep are important parts of how healthy we are,” says Steven Shea, director of the Sleep Disorders Program at Brigham and Women’s Hospital in Boston.

One way to learn about how our body clocks tick is to mess them up and see what happens. That’s what neurologist（神经病学家）Frank Scheer and his workmates did in a recent study. Staying up night after night, their studies suggest, could make kids extra hungry and more likely to gain weight. And regularly sleeping too little, Scheer says, may be one cause of the recent increase in childhood obesity.

1.What will happen if you forget about the clock according to the passage?

A. You will feel upset.

B. You will behave normally.

C. Your body will not know what time it is.

D. You will probably get hungry more easily.

2.Mike feels energetic at 12 midnight while Tom feels sleepy. What advice would be given by the writer?

A. Both should see a doctor..　　 B. Tom should see a doctor.

C. Both should take it easy.　　 D. Mike should have a watch.

3.How do Frank Scheer and his workmates study body clocks?

A. By seeing what happens when they are messed up.

B. By asking questions and collecting answers.

C. By studying people traveling across time zones.

D. By programming people with man-made clocks.

4.What will the writer most probably talk about next?

A. Other examples of what people will do when their body clocks go wrong.

B. Some effective medicines that can keep people from putting on weight.

C. Why it is important to have a normal body clock.

D. What circadian rhythms are and how they work.
