Eating too much fatty food，exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.
Previous studies have linked high exposure（暴露）to environmental pollution to an increased risk of heart problems, but two analyses now show that poor air quality can cause heart attack or stroke（中风） within as little as a few hours after exposure. In one report of the research, scientists found that people exposed to high levels of pollutants（污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. Another study of stroke patients showed that even air that the U.S. Environmental Protection Agency（EPA）considers to be of “moderate”(良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

Growing up, I knew I was different. My father had left and he never came back. As I later discovered, the abandonment triggered my anxiety attacks. I feared being alone, unwanted, unpopular, and unloved.
My first attack came in a ninth-grade class: The teacher asked me to walk in front of the class, but I couldn't do it- I was soaked in sweat, shaking. My symptoms began every morning from the moment when I stepped inside the school building.
Throughout my childhood, I was no stranger to the doctor's office. My mother tried everything she could in hope of a breakthrough. There were times I thought suicide could be the only way to make the pain stop.
By age 16, I had shut down socially. Most of my peers were going to parties, playing sports, and dating. But I was a prisoner in my own home.
Then one Sunday morning, my wake-up call came from a magazine article. Freddie Prinze, Jr. was on the cover. The article detailed the pain of losing his father at a young age. I felt as though I were reading my own life story. The only difference? He was now a success.
That article inspired me to explore a new treatment option for myself. I wanted to turn my life around as well. So I hit the library and the Internet, and I began to realize how my negative thoughts controlled my physical well-being.
Immediately, I made a plan to take charge of my life. Shortly after following the items I had listed, I was able to stop seeing a therapist. I never returned to high school, but I did go to college. After graduation, I pursued a career in television news. My relationships have changed for the better, too. I've made new friends and reconnected with many from my past
The anxiety isn't completely gone, but whenever it returns, I know the feeling will pass, and know I have the power to change my life, only if I will give myself a chance.The writer's anxiety attacks were mainly caused by .
| A．the high school which he attended | B．the teacher who asked him to walk |
| C．the writer himself who was fearful | D．the father who left in his childhood |
The breakthrough of the writer's treatment came when________.
| A．the mother took him to the doctor | B．the writer read a magazine article |
| C．the writer's pain finally stopped | D．the writer went to college |
What did the writer do after following the plan?
| A．He went to see therapists. | B．He returned to high school. |
| C．He contacted his old friends. | D．He didn't suffer any attacks. |
The writer wrote this story to tell us________.
| A．anxiety attacks are not lasting if we have proper treatment |
| B．we shouldn't keep ourselves away from the outside world |
| C．we can change our lives if we give ourselves a chance |
| D．fathers are not supposed to abandon their small kids |

Many Chinese kids, known as "left-behind" children, hardly ever see their parents, because their parents are migrant workers.
Li Ling, 11, is a left-behind child. Her parents have been working in Zhejiang for 10 years, while she lives with her grandparents in Guangdong. She was reunited with her parents last Spring Festival. As the number of migrant workers in China increases, the number of left-behind children is rising fast. Li is one of the 61. 02 million left-behind children under 17. They account for 37. 7 percent of rural children and 21. 88 percent of all Chinese children
The large number of left-behind children has already become a social issue. If left unsolved, it will cause serious problems, Wang Zhenyao, director of the China Philanthropy Research Institute, told China Daily. The education level of adults supervising（监管） these children is generally not that high. They can only take care of the children's personal safety and daily living, being unable to care for their educational and spiritual needs. Meanwhile, the absence of parental support will make some left-behind children lack self-confidence. They may be slower in physical and emotional growth than their peers. Others may even become "problem youths".
To solve this problem, the government is taking action. For instance, 30 provinces and cities have allowed certain children to attend school and take the college entrance exam in the city where their parents are. However, Wang suggested that the country do more, such as making policies encouraging migrant workers to work in their hometowns. He also said that a well-balanced child welfare system is needed. "These children are the future of the nation, so they deserve our loving care and protection," Wang said.Left-behind kids hardly see their parents because _______.
| A．they are poor and in rural areas |
| B．they are brought up by their grandparents |
| C．their parents are making a living in other cities |
| D．their parents don't go back home on Spring Festival |
Which of the following is true according to the passage?

| D．Much remains to be done to settle the left-behind kids issue. |
The purpose of the passage is _______.
| A．to criticize the migrant workers who leave their children at home |
| B．to focus on the present situation of the left-behind children |
| C．to worry about the present situation of left-behind children |
| D．to call on the government to educate the migrant workers |
In which column of a newspaper can we most probably find this passage?
| A．Education. | B．Society. | C．Entertainment. | D．Employment. |
There was great excitement on the planet of Venus (金星) . Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan, named after the great Venusian astronomer Professor. Manhattan, who first discovered it with his telescope 20000 light years ago.
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer landing on Earth. A press conference was held at the Venus Institute of Technology.
"We have come to the conclusion, based on last week's satellite landing," Prof. Zog said, "that there is no life on Earth."
"How do you know this?" the science reporter of the Venus Evening Star asked.
"For one thing, Earth's surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive."
"What does this mean as far as our flying saucer program is concerned?"
"We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned."
"Are there any other dangers that you discovered in your studies?"
"Take a look at this photo. You see this dark black cloud hovering (盘旋) over the surface of Earth? We don't know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there."
"Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer."
"If all you say is true, won't this set back the flying saucer program several years?"
"Yes, but we shall continue as soon as the Grubstart gives us the added funds(资金)." Profession. Zog replied. According to the passage, the Venusian scientists succeeded in getting important information about _____.
| A．the feasibility of landing a satellite on Earth |
| B．the possibility of making a first-rate flying saucer |
| C．the feasibility of sending a Venus Being to Earth |
| D．the possibility of directing a flying saucer into Manhattan |
Why will the Venusian have to take their own oxygen with them when they carry out their flying saucer program because _____.
| A．they need it in their way to the planet of Earth |
| B．the Earth's atmosphere is filled with deadly gases |
| C．there is a low level of oxygen for Venusians |
| D．there is no air on the planet of Earth |
It can be inferred from the passage that ______.
| A．landing a manned flying saucer on Earth will be carried out soon |
| B．Venusians will land on Earth to help to stop serious pollution |
| C．it’s unnecessary to land a manned flying saucer on Earth at present |
| D．pollution on Earth makes it impossible for Venusians to survive there |
Where can you probably read such a passage?.
| A．In a popular magazine. | B．In a fairy tale. |
| C．In an observation journal | D．In science fiction |
In 1980，Candy Lightner’s 13-year-old daughter Cad was killed by a drunk driver as she walked down a suburban street in California. “I promised myself on the day of my daughter’s death that I would fight to make this needless accident count for something positive in the years ahead,” Candy Lightener later wrote.
The drunk driver received a two-year prison sentence. However, he avoided prison by serving time in a work camp and a halfway house. Ms. Lightner was very angry about that and so organized Mothers Against Drunk Drivers (MADD), which later changed to Mothers Against Drunk Driving. The aim of her organization was to raise public awareness of the serious nature of drunk driving and to promote tough legislation against the crime.
Before Ms. Lightner’s MADD, intoxication (醉酒), including drunk driving, was not taken seriously. Intoxication was often used as an excuse for otherwise unacceptable behavior: “I didn’t know what I was doing—I was drunk.”
Candy Lightner appeared on major television shows, spoke before the US Congress, addressed professional and business, groups, and worked tirelessly for years to change public attitudes, change judicial(审判的) behaviour, and promote tough new legislation. Ms. Lightner left MADD because the organization that she herself created is changing its focus. “I didn’t start MADD to deal with alcohol. I started MADD to deal with the issue of drunk driving.”
The President of the United States awarded her the President’s Volunteer Action Award and she was the subject of the movie “Mothers Against Drunk Drivers: the Candy Lightner Story”.One of the purposes of MADD was to______ .
| A．make the public aware of the danger of drunk driving |
| B．fight against the drunk hit-and-run drivers on the road |
| C．make new laws against crimes caused by drinking |
| D．warn people not to drink alcohol while driving |
which way didn’t Ms. Lightner use to achieve her MADD’s goals?
| A．Talking on major TV shows. |
| B．Giving a talk to businessmen. |
| C．Applying for a job with the government. |
| D．Giving suggestions to the US Congress. |
We can learn from the passage that______.
| A．the drunk driver had not been caught |
| B．drunk driving didn’t receive enough attention before MADD |
| C．Candy Lightner played a leading role in a film |
| D．MADD didn’t get much support from society |
What would be the best title for the passage?
| A．Ways to prevent drunk driving |
| B．Purposes of founding MADD |
| C．New law against drunk driving |
| D．Candy Lightner and her MADD |
