Sit Up Straight: Tips for Improving Your Terrible Posture
The more time we spend sitting in front of our computers, the worse our posture gets. Modern technology is turning us into literally twisted creatures.
In addition to being detrimental to how your body functions, bad posture isn’t cute. It causes you to jut(突出) your hips forward, slump your shoulders, and even breathe inefficiently, according to Pat Davidson, a trainer with a PhD in Exercise Physiology who is the Director of Training Methodology and Continuing Education Coordinator at Peak Performance in NYC.
Davidson explained that bad posture compromises your diaphragm(隔离), the big muscle right below the ribs that helps you take deep breaths. So instead, you start using other muscles, like your shoulders, to help you breathe. It turns out that people with lousy posture don’t walk correctly, and they count on their lower back muscles to help propel themselves forward.
Here are a few quick fixes recommended for correcting your slump:
• If you sit at a desk all day, don’t perch on the edge of your chair at work trying to sit up straight. The best thing you can do is keep your hips against the back of the chair and use it for support—that’s what it’s there for.
• Get up frequently and walk around.
• If you carry a heavy shoulder bag, make sure to carry it on both your right and left shoulder, switching off as each gets tired. Even better: wear a cross-body bag so that the weight’s more evenly distributed.
• Work out your core muscles. You can try backwards jump-roping. If the rope hits you, you have the wrong posture. Hula hooping is also a good choice.
• Focus on the upper back and shoulder muscles. One of her favorite exercises is having clients stand up against a wall, with your hips touching the wall. Put a tennis ball between your shoulder blades and try to squeeze the ball. Boating is also excellent for improving posture, since it causes you to pull your shoulders up and back.
According to the passage, a bad posture can_____.
a. stop us from taking deep breathes
b. functionally change our body
c. hurt our diaphragm
d. make our walking posture incorrect

A．bcd

B．acd

C．abc

D．abcd

Domestic airline passengers will be able to make phone calls and send e-mails from the sky from next year, a local carrier has said.
Shenzhen Airlines said on Monday it has signed an agreement with Geneva-based On-Air to provide passengers with in-flight communications services on all its planes by the end of 2009. The service will be introduced on three aircraft ahead of the 2008 Olympics, on two routes----from Shenzhen to Beijing and Shenzhen to Shanghai, the airline said.
Passengers will be able to use their own electronic devices to send e-mails and short messages, make calls and surf the Internet, it said. The service is expected to be of particular interest to business travelers.
According to a survey at the end of last year, China had 4.55 million mobile-phone subscribers. Ninety-three percent of those polled said they wished they could send and receive e-mails and messages while on a plane.
Despite the introduction of the new service, passengers will still be prevented from using t heir cell phones and laptops when the plane is taking off and landing, or flying at less than 3,000 m above sea level, the official said.
The official said the new service would not lead to an increase in ticket prices, but users of Chinese mobile-phone services will be charged the international roaming rate for any calls made from the sky.
Shenzhen Airlines is the first Chinese carrier to provide such in-flight communications services. Its president, Li Kun, said installing the facilities will cost 4.5 million yuan ($596,000) per aircraft. However, the project still needs to be approved by the Civil Aviation Administration of China, a source said.

I like friends who share my happiness and sorrow,and who possess wings of their own and fly with me. I seek friends whose qualities illuminate(照亮)me and help me to express my love. It is for these people that I reserve the glowing hours, too good not to share.
When I was in the eighth grade, I had a friend. We were shy and “too serious” about our studies when it was becoming fashionable with our classmates to learn acceptable social behaviors. We said little at school, but she would come to my house and we would sit down with pencils and paper, and one of us would say,“Let’s start with a train whistle today.” We would sit quietly together and write poems or stories that grew out of a train whistle. Then we would read them aloud. At the end of that school year, we too, were changing into social creatures and the stories and poems stopped.
When I lived for a time in London, I had a friend. He was in despair(失望) and I was in despair, but our friendship was based on the idea that we would be sorry later if we did not explore this great city because we felt awful at the time. We met every Sunday for five weeks and visited many wonderful places. We walked until our despair disappeared and then we parted. We gave London to each other.
For almost four years I have had a remarkable friend whose imagination illuminates mine. We write long letters to each other in which we often discover our strangest selves. Each of us appears, sometimes in a funny way, in the other’s dreams. She and I agree that, at certain times, we seem to be parts of the same mind. In my most interesting moments, I often think: “Yes, I must tell…” We have never met.
It is such comforting companions I wish to keep. One bright hour with their kind is worth more to me than the lifetime services of a psychologist(心理学家), who will only fill up the healing(愈合的) silence necessary to those darkest moments in which I would rather be my own best friend.
1. In the eighth grade, what did the author do while her classmates started developing proper social behavior?
A. Become serious about her studies.      B. Went to her friend’s house regularly.

Few people would question the value of taking part in sports for young people. With proper training, supervision, protective equipment and techniques, and a proper emphasis on winning, sports can develop a healthy body and spirit and a life-long interest in being active and fit. Without such measures, childhood sports can lead to injuries and even paralysis or death.
Even in the best conditions, no activity can be risk-free. But most serious hazards are preventable. Cyclists and football players can reduce their risks by wearing helmets, hockey players by wearing masks; basketball and tennis players by wearing eye guards; baseball players by wearing batting helmets. Besides, risks to individual players can often be found, and thus prevented, through a properly performed medical exam before a child plays. For accidents that may not be preventable, having an emergency plan and first-aid equipment, and someone trained to use the equipment, can be lifesaving.
Still, each year, according to the American College of Sports Medicine, more than 775, 000 children under 14 are treated in emergency rooms for sports injuries, nearly half of them preventable. An estimated 300,000 athletes experience exercise-related head illnesses each year, and almost all of them should have been avoided.
Further, from half to three-fourths of sports-related concussions(脑震荡) are never even diagnosed; the injured are often sent back to play too soon and put at risk of another more serious brain-damaging concussion. To help reduce these risks, the National Center for Sports Safety, with the National Athletic Trainers’ Association, offers a three-hour online safety course for coaches for $28 at www. SportsSafety. Org.
1 Which of the following is true according to the passage?
A. All the accidents can be prevented.        B. All the accidents cannot b e prevented.
C. Lives can be saved so long as there is proper equipment.
D. Lives cannot be saved even if there is proper equipment.
2. What does the underlined word “hazards” (in Paragraph 2)
A. Mistakes.       B. Diseases.      C. Dangers.     D. Situations.
3. It is implied in the passage that _____________.
A. prevention of injuries is not paid enough attention to
B. children under 14 are more easily hurt in sports
C. most head illnesses are related with exercise
D. none of the head illnesses should have happened
4. What can coaches mainly learn from the online safety course?
A. How to cure brain-damaging concussion.    B. How to diagnose brain-damaging concussion.
C. How to predict the possibility of brain damage.  D. How to deal with the injured properly.

Mary went out at night. She never forgot the night when she met a robber many years ago.
That evening, she was invited to a birthday party which lasted until two o’clock i n the morning. Without company Mary walked along the quiet street.
Suddenly from the shadow of a dark building a tall man with a sharp knife in his right hand ran out at her. “Good evening, lady,” the man said in a low voice, “I don’t think you wish to die here.”
“What do you want?” Mary asked.
“Your earrings （耳环）.Take them off!” Slowly Mary’s eyes looked down. She tried to cover her necklace with the collar（领子）of her overcoat while she used the other hand to take off both of her earrings, and then she quickly threw them on the ground.
“Take them and let me go.” she said. The robber looked at her only feeling uncertain. He saw the girl didn’t care for the earrings at all, only trying to protect the necklace. He realized the necklace would cost more. So he said, “Give me your necklace.”
“Oh, sir. It’s not worth much. Please let me keep it.”
“Stop rubbish. Quick!”
With shaky hands, Mary took off her necklace. As soon as the robber disappeared, she picked up her earrings and ran as fast as she could to one of her friends.
