A headache is the feeling you get when your head hurts. Headaches can differ from very mild to incredibly powerful. They can last anywhere from 10 minutes to hours. Very bad headaches are called migraines. People who suffer from migraine headaches often need to take the day off from school or work and lie in bed all day.

Why do people get headaches? There are many possible causes. People who drink too much caffeine (in coffee or soft drinks, for example) or alcohol can end up with headaches. This is because these kinds of drinks take water away from the body. If the brain doesn’t have enough water, it gets smaller and pulls away from the head. This can be extremely painful. The best way to get rid of this kind of headache is just to drink lots of water.

Tension headaches happen when the body's muscles are too tight. When people feel stress, it is common for the muscles near the head to become tense. Tension headaches might also be caused by not getting enough sleep. Some people suffer from tension headaches for only short times but for other people, these kinds of headaches are a chronic problem that happens again and again. A massage (按摩) might help to stop a tension headache. If that doesn't help, you might need to see a doctor.

Headaches can also be caused by much bigger health problems. For example, a head or neck injury can cause them. Headaches can also be a warming sign of a heart attack.

2.Why can caffeine cause headaches?

Press your fingers into the back of your head, just above your neck. If you feel a small bony bump (突起), you will find evidence of human evolution: it could be your body responding to common smartphone use in the 21st century.

According to a recent study, published in Scientific Reports, young people increasingly have bony bumps at the base of their skulls (颅骨) right above the neck. Medical professionals call them enlarged external occipital protuberances(EEOPs, 枕外隆突).

Australian health scientist David Shahar, author of the study told the BBC that over the past 10 years, he’s seen more and more patients with EEOPs. Together with other researchers from the University of the Sunshine Coast, Australia, they examined 1200 skulls x-rays from people aged 18 to 30. They also measured the bumps and noted each person’s posture (坐姿).

They found that one in four people have developed these growths. This led to their theory that smartphones are the cause.

According to their research, looking down at their phones adds the stress onto the top of our spines (脊柱). To prevent damage to our spines, Shahar believes our bodies add fresh bony bumps to help reduce the extra stress.

Most of the EEOPs measurea just a few millimeters. However, several subjects were found with EEOPs as large as 30 mm.

In his report, Shahar said the results “highlighted the need” for prevention. In other words, we need to change our posture while using our phones.

Many people assume our bones are solid and are unmoving once we reach adulthood. In reality, they are alive and covered with blood vessels (血管), which allows them to develop in unique ways for each person.

Aside from EEOPs, other noticeable recent changes in human bodies include smaller jaws, elbows and skeletons (骨格). The human body is changing with modern life. So who knows what people in the future might look like?

1.What did the recent study find about EEPOs?

A.They grow on one’s neck.

B.They could lead to many mental problems.

C.They increasingly occur among young people.

D.They may stop growing when they reach 30.

2.What is the main cause of EEPOs?

A.Gene problems. B.Cellphone use.

C.Blood vessels. D.Extra stress.

3.Which of the following would Shahar probably agree with?

A.EEPOs increase the stress on our spines.

B.Young people’s bones develop in similar ways.

C.EEPOs are actually beneficial to our spines.

D.Young people should exercise to improve their posture.

4.What’s the main purpose of the text?

A.To persuade readers to protect their spines.

B.To recommend some healthy habits of using phones.

C.To show some recent changes in human bodies.

D.To explain why human bodies develop EEPOs.

When you cough or sneeze, you’d better turn your head away from others and cover your mouth with the full part of your hand. And then, you should say, “Excuse me.”

This seems so simple, but it is surprising how many kids have never been told to do this. Actually, I notice adults all the time who cough and sneeze in public without placing a hand over the mouth. One important thing I point out to the kids is that after they sneeze or cough on their hands, they should wash their hands as soon as possible. If not, they will be passing those germs (细菌) along to everything and everyone they touch.

If you come to a door and someone is following you, hold the door. If the door opens by pulling, pull it open, stand to the side, and allow the other person to pass through first, then you can walk through. If the door opens by pushing, hold the door after you pass through.

After a few weeks of seeing kids try to get through doors in the school and watching them enter restaurants as the door hit other people, I knew I had to discuss the problem with my students. Teaching them small acts of kindness, such as letting someone else go through a door first as they hold it open, may seem unimportant, but it can go along way toward helping students realize hot to be polite and thank others. Once they’ve been told, they’re halfway there.

When we have to go up moving stairs, we will stand to the right. That will give others who are in a hurry a choice of walking up the left-hand side of the moving stairs. When we are going to enter a lift, the underground, or a doorway, we will wait for others to exit before we enter.

After college when I moved to London, I was surprised at how polite everyone was in the subways. I was even more touched when I traveled to Japan. In both places, people made efforts to make way for others. On moving stairs, everyone stood to the right and walked to the left. On lifts, everyone would stand over to the side and allow others to exit before they would begin to enter.

1.When you cough or sneeze, you should ________.

A. touch everything             B. cover your mouth

C. point out to the kids        D. pass the germs to others

2.If you come to a door and someone is following you, you’d better _______.

A. hold the door  B. pass through  C. close the door  D. stand to the side

3.From the passage we ca know the writer is a ________.

A. doctor       B. traveler             C. parent               D. teacher

4.A. The passage is mainly about ______.

A. the rules of behavior in public          B. the easy of communication

C. the acts of kindness among people        D. the knowledge of social life

It is a cold and dry winter morning. When you wake up, you feel that your throat hurts. You begin to sneeze and later you may cough. You must have a cold! Wait a moment. Could it just be a common cold or the flu that’s been going around?

A cold gives you a runny nose and cough. But it’s usually easy to deal with. Some take medicine while others drink herbal tea or chicken soup. Usually you feel better after a week.

On the other hand, the flu can be much more dangerous. It usually gives you fever.

Sometimes it can cause death. According to an American magazine, the worst flu killed about 50 million people from 1918 to 1919.

Don’t worry. If you get a flu vaccine（疫苗）, it can stop you from getting the virus. Flu vaccines work by giving the body a small amount of flu viruses. This causes your body to develop antibodies. So next time you get the flu, the antibodies should help you.

The flu virus changes every few years. Therefore, there are so many types of flu, such as H1N1 and H5N1. The antibodies for one type of flu can't help us against all types of flu. That’s why we need to get vaccine every year.

However, good health habits may also help stop you developing a cold or flu. Washing your hands often helps stop you from getting viruses. It is also important to get regular exercise and eat healthy food. All these can help you strengthen your immune system.

1.According to the passage, which is TRUE of the flu?

A. It first happened in 1919.

B. It usually doesn’t give you fever.

C. It is easy to deal with.

D. It can kill people sometimes.

2.If you get a flu vaccine, ________.

A. it can’t stop you from getting the flu virus

B. it won’t cause your body to develop antibodies

C. your body will develop antibodies

D. your body will get a large amount of flu viruses

3.We need to get a flu vaccine every year because ________.

A. we probably have a cold in winter

B. the flu virus changes every few years

C. the flu is very dangerous

D. you don’t need to take any medicine after that

When you think of all the ways your body can get hurt---falling off a bike, stepping on a nail, being bitten by a crazed dog---the aches and pains that come from sitting at a computer may not seem like much.

But more doctors are getting worried about just that. If you sit at a PC the wrong way, the nerves and muscles in your back, neck and arms can get out of line.

Ergonomics is the study of how people work and how jobs and equipment can be designed so that people are safer and more comfortable in the things they do---whether that’s working on a factory assembly line or sitting in front of a computer.

The monitor

You should not have to tilt（倾斜） your neck up or down to lock at the screen. Your eyes should be level with the top of the screen.

How far away should you sit? Reach your arm out so your fingertips just touch the screen.

The keyboard

It should be directly in front of you. Don’t unfold the legs on the bottom of the keyboard so that it tilts up toward you---it should be as flat as possible, or even tilted away from you. You want your wrists “neutral,” which means straight, not bent. This puts less strain on your nerves and muscles.

Arms should be close to the body. Don’t look at your fingers as you type. Use a document holder to hold papers at the same level as the monitor. Keep the mouse on the same level as the keyboard and close by--- so you don’t have to reach for it.

The chair

Your feet shouldn’t dangle---the blood will pool in your feet. They should rest flat on the floor, or on phone books, if necessary. Your back needs support. Roll up a towel and stick it there.

The Body

If you think of your body as a collection of right angles when you sit at a computer, you should be just fine.

Your hips should be at a 90-degree angle to your back. That takes the pressure off the spine. And your knees should bend at a 90 degree angle so your feet are flat.

1.The passage mainly talks about________.

A．avoiding pains caused by using PC           B．the science of ergonomics

C．illness caused by a computer               D．how to keep fit

2.The underlined word “ergonomics” most probably means ______ in Chinese.

A．管理学           B．人机工程学        C．机械工程学        D．经济学

3.How high should a monitor be placed according to the passage?

A．As high as your arms.

B．A little higher than your eyes.

C．A little lower than your eyes.

D．At the same level as your eyes.

4.How shouldn’t a keyboard be placed?

A．Tilting away from you.                    B．Tilting up toward you.

C．Flat.                                  D．Not mentioned.

5.How should you place your foot?

A．Rest them on a phone book.               B．Rest them on the floor.

C．They should rest flat.                     D．They should dangle.

Ever feel like you’ve been hit on the head after a bad night’s sleep? According to scientists, the thought isn’t as unbelievable as it seems.

A study found going without sleep for just one night causes changes in the brain similar to those that happen after a blow to the head. The researchers said the healthy young men examined in the study showed a sudden rise in the same chemicals which indicate(表明) brain damage. Professor Christian Benedict, of Uppsala University, Sweden, explained that the chemicals NSE and S-100B are biomarkers(生物指标) for brain damage, such as concussion(脑震荡). He said, “What we found was their levels in the blood rose in the group that went without sleep for a night. This was not to the degree that would happen after a head injury, for example, but it was still worth paying attention to. During sleep, the brain cleans itself of poisonous substances.” He said the findings support the previous(以前的) research showing how the brain makes use of sleep to clean itself.

Professor Benedict also said his study could support previous studies which linked a lack of sleep with increased risk of Alzheimer’s and Parkinson’s diseases. The rise of the chemicals in the blood after sleep loss may suggest not getting enough sleep leads to a loss of brain tissue, he explained. Professor Benedict, whose study is published in the journal Sleep, added, “In conclusion, the findings of our trial indicate a good night’s sleep may be very important for keeping brain health.”

A third of the UK population suffer from sleep-related problems, while the average person now sleeps for only seven hours a night, compared with almost nine a few decades ago. Many scientists believe irregular sleeping patterns lead to illnesses ranging from aches and pains to heart disease, while less than eight hours’ sleep a night can lower the IQ the next day.

1.If you don’t sleep for a night, what will happen?

A. There will be a rise in the chemicals NSE and S-100B

B. The chemicals NSE and S-100B will drop to a lower level

C. Some of the chemicals NSE and S-100B will change into other matters

D. The chemicals NSE and S-100B will be less able to get rid of poisonous matters

2.What is the previous study mainly about according to the passage?

A. The way to avoid brain damage

B. The ways to improve the quality of sleep

C. The ways that have effect on people’s sleep

D. The way the brain uses sleep to clean itself

3.We can we infer from the last paragraph that　　　 .

A. man’s intelligence is affected by sleep in a way

B. people who need more sleep have a higher IQ

C. one fourth of the UK population have sleep-related problems

D. modern people need less sleep than those a few decades ago

4.What’s is the theme of the passage?

A. Eight hours’ sleep is important

B. How human brains work during sleep

C. Sleep loss is close to a blow to the head

D. Regular sleeping patterns improve health

When a storm is coming, most people leave the area as quickly as possible and head for safety. But there are a few people who will get into cars and go straight for the center of the storm. These people are willing to risk being killed by floods or 100-kilometer-an-hour winds for the excitement of watching the storm close up.

“Storm chasing (追逐)” is becoming an increasingly popular hobby, especially in the Midwest of the United States, where there are frequent storms between March and July. A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to 1,000 kilometers to where the storm will be and waits for it to develop.

Although anyone can do it, storm chasing is extremely dangerous. The power of a big storm can throw a cow into the air or destroy a whole house in seconds. Storm chasers are also often hurt in accidents caused by driving in a heavy rain. If you are a beginner, it is much safer to join a group for storm-chasing vacations during the storm seasons.

Even then, storm chasing is not all adventure and excitement. “Storm chasing is 95% driving,” says Daniel Lynch, who spends most of his summer storm-chasing. “Sometimes you can sit around for hours waiting for something to happen, and all you get is blue sky and a few light showers.”

However, for storm chasers, it is all worth it. “When you get close to a storm, it is the most exciting sight you will ever see in your life,” says Jasper Morley. “Every storm is an example of the power of nature. It is the greatest show on Earth.”

1.For storm chasing, the first thing storm chasers do is to ____.

A.get quickly into their cars for safety

B.wait patiently for the storm to develop

C.head straight for the center of the storm

D.collect information about a coming storm

2.Beginners of storm chasing are advised ____.

A.to do it in an organized way B.to spend much more time on it

C.not to get too close to a storm D.not to drive in a heavy rain

3.By saying “it is all worth it” in the last paragraph, the author means that ___.

A.storm chasing costs a lot of money B.efforts in storm chasing are well paid

C.storm chasing is worth hours of waiting D.a storm presents the greatest show on Earth

4.What can we learn from the text?

A.Storm chasing is only fit for young people.

B.Some storm chasers were killed during the storms.

C.Storm chasing is becoming popular around the world.

D.Sometimes storm chasers get nothing but disappointment.
