It’s reported that many people died of traffic accidents each year. Road safety has aroused the widely attention of the public. Many rules have made to reduce the traffic crashes, especially for the ones involved in the pedestrians. In my opinion, we should make road safety seriously in our daily life. While used the road, we must walk on the pavement and learn to protect us. Besides, car drivers should obey the traffic rules, that is both good for themselves and others.
In the word, obeying the traffic rules are what all of us should pay attention to particularly. After all, life is not a small matter.
Doctors Say Most Heart Disease Preventable
Heart disease is the number one killer, worldwide, of men and women over the age of 60. But people of all ages die of heart attacks each year. And while death rates have declined in the U.S. and many western European countries, they are on the rise in the developing world. 1. .
No one would have guessed that Barbara Teng would have a heart attack. She was not overweight. She did not smoke or exercise.“In 2004, the week after I turned 49, when I was on a business trip in Chicago, I had a major heart attack," she said. 2. . She now exercises daily, and monitors her heart health.
Dr. Patrice Nickens, who is with the National Heart, Lung and Blood Institute, thinks that heart disease is 82 percent preventable. “3. ,” she said, “Men are also facing the same problem, and the key to staying healthy is knowing your numbers”.
“Your weight, your blood cholesterol, blood sugar and your blood pressure are important numbers that can help you take action and reduce your risk,” she said.
4. .
“And the steps to take are simple: don’t smoke, maintain a healthy weight, exercise, know your numbers and talk to your physician and control these risks,” she said.
African-Americans are at higher-than-average risk for heart disease and stroke; people don't even know they have it, which increases the risk. Medstar Washington Hospital Center is trying to reach this population. 5. . For example, helping the people monitor their blood pressure. If people realize they are at risk for heart disease, they'll make lifestyle changes: lose weight, exercise, eat the right foods and keep in touch with a doctor
A. A healthy lifestyle can prevent heart disease
B. So we must cure heart disease
C. It is the leading cause of death for women
D. With the right training, they can play an important role in community health
E. And that changed her life
F. Lack of exercise causes heart attacks
G. Yet most heart disease is preventable.
On Jan 23, 2012, I was aboard a ship on the Yangtze River, listening to the sound of fireworks and eating plate after plate of dumplings.
On Sunday Feb 10, 2013, I was preparing to celebrate Chinese New Year again – in London’s Chinatown.
It was raining. It was cold. But ever since I left Beijing in August, I had promised myself I would celebrate Chinese New Year – if only to help with my Beijing “homesickness”.
Central London was dressed up for the occasion. There was a stage for a big fireworks display for the evening. Even so, it wasn’t like my real Beijing chunjie.
Even buying a baozi didn’t cheer me up. It cost about 10 times as much as the real thing does in Beijing and got stuck to its rain-ruined paper bag.
Cold, wet and depressed, I ran into a shop for shelter. Suddenly, there it was. Between the packets of dried meat and fish, the bags of rice and the smell of dried noodles in this little Chinese supermarket, I had found home.
An hour later, I hurried into my house with bags of frozen jiaozi, packets of sauce and a large bottle of vinegar. I boiled water, tore open the packets, grabbed my chopsticks and settled down to a feast. This, I thought, is a Happy Chinese New Year.
I even watched the fireworks on TV. After all, why face the British weather when I can bring China home in one bite?
1. We can conclude from the first three paragraphs that the author ______.
A. likes watching fireworks on the boat
B. misses Chinese food more than anything else
C. finds it great fun to celebrate Chinese New Year
D. misses her life in Beijing very much
2.How did the author feel when she found some Chinese foods in a supermarket?
A. a little curious B. rather tired

A. She didn’t want to get wet and cold again.
B. The square is far away from where she lives.
C. She doesn’t like fireworks very much.
D. She was too hungry to go out.
4.What is the best title of the passage?
A. Unforgettable Chunjie in Beijing B. Wonderful Experience in Britain
C. Finding Home in London D. Festival in London
Sixty-five million years ago, an asteroid (小行星) that crashed on Earth led to the disappearance of the largest animals that have ever walked our planet – the dinosaurs. At least, this is what some scientists believe. But that accident happened so long ago. People have come to believe that we are free of threats from asteroids and everything else from space.
However, what happened on Feb 15 , 2013 was a reminder that we’re just as vulnerable as the dinosaurs once were. Two objects from space – a meteor (陨石) and an asteroid called 2012 DA14 – visited Earth’s atmosphere on the same day. The former fell in Russia, injuring 1,200 people, while the latter passed by Earth at a record-setting close distance.
Scientists had been expecting the asteroid since last year, but the meteor was a surprise. NASA’s telescope system only detects asteroids at least 50 meters in diameter (直径), which is just about the size of 2012 DA14. But the meteor was much smaller, which made it harder to spot.
But what if we do spot an asteroid that is headed right for Earth? There are several possible ways in which dangerous asteroids could be made to change its orbit. Which method is best depends on several factors and most importantly – how much time we have to stop it.
If there is enough time before the hit, we can send off a heavy spacecraft to travel alongside the asteroid. The gravity from the spacecraft would gradually change the rock’s orbit. Besides that, scientists could one day use sun-powered lasers to either make asteroids disappear or change their course. If there’s not enough time, we’ll have to go after the asteroid with a spacecraft and change its orbit with a crash. Finally, if things are truly desperate, there will be only one choice left – to use a nuclear bomb. That could turn the asteroid into a meteor shower, which would be even more dangerous.

C. It is about the same size as the asteroid that passed by the Earth.
D. It fell to the Earth and caused great damage to the local community.
