Pollutants have gradually accumulated over the course of recent windless days，making the air quality even worse，”said Zhu Tong, a professor from the college of environmental sciences and engineering at Peking University.“Private stock firms are seeking opportunities to invest in clean technology companies in China，especially those that may help to reduce air pollution longterm.However，there is a long way to go before the offthelevel smog is stopped，”Yu Jianhua added.The pollution is expected to swallow Beijing until Wednesday，when wind will arrive to blow the smog away, according to a weather report from the weather station.1．Beijing carried out its emergency response plan to________.A．answer the call of environmental authoritiesB．meet the demand of environmental authoritiesC．follow the order of the weather stationD．deal with the damaging health effects of pollution2．Which of the following is true of the news?A．The weather has worsened the situations.B．The weather station announced the city’s red fog warning.C．The plan ordered construction sites to stop construction activity.D．Air quality indexes in most districts have hit 993.3．According to Yu Jianhua, ________.A．it won’t be long before air pollution is reducedB．it isn’t easy to reduce air pollution in a very short timeC．it isn’t necessary for people to do more about air pollutionD．it is impossible to get rid of air pollution4．What is the passage mainly about?A．Beijing’s air quality indexes and readings for PM 2.5.B．Beijing’s emergency response plan for pollution.C．Smog covers Beijing and the air is heavily polluted.D．Clean technology companies help to reduce air pollution.BCarbon monoxide (一氧化碳) poisoning kills and injures many people and animals around the world. The gas has been a problem since people first began burning fuels to cook food or to create heat. It is a problem in all parts of the world that experiences cold weather.Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color. It has no taste. It has no smell. It does not cause burning eyes. And it does not cause people to cough. But it is very deadly. It robs the body of its ability to use oxygen.Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues.It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it.Damage to the body can begin very quickly from large amounts of carbon monoxide. How quickly this happens depends on the length of time a person is breathing the gas and the amount of the gas he or she breathes in.Carbon monoxide poisoning has warning signs. But people have to be awake to recognize them. Small amounts of the gas will cause a person’s head to hurt. He or she may begin to feel tired. The person may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly. People develop severe head pain as the amount of gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomach pains.Medical experts say carbon monoxide affects people differently. For example, a small child will experience health problems or die much quicker than an adult will. The general health of the person or his or her age can also be important. An older adult with health problems may suffer the effects of carbon monoxide more quickly than a younger person with no health problems. People with heart disease may suffer chest pains. They may begin to have trouble breathing.5．Why is carbon monoxide called the silent killer?A．Because it tastes and smells good.B．Because it is not easily noticed.C．Because it kills and injures people.D．Because it always harms people.6．How does carbon monoxide harm people?A．It makes people’s blood unable to move.B．It decreases the amount of blood in the body.C．It makes body tissues full of blood.D．It makes the blood less able to carry oxygen.7．When people breathe in small amounts of the gas, they may ________.A．feel a little dizzy B．suffer a severe headacheC．go around in the room D．have a terrible stomachache8．Which of the following about carbon monoxide poisoning is TRUE?A．Adults are affected more seriously than children.B．Young people are more severely affected than old people.C．People in poor health may have more severe consequences.D．People with heart problem only suffer from chest pains.CSince the beginning of the year, smog has covered parts of North China. In January, Beijing saw only five days without smog. The rising PM 2.5 readings terrified many people, and some health experts said that whenever the smog gets serious, hospitals receive more patients suffering acute respiratory (呼吸系统) and heart diseases.Later, news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.So the need to emphasize environmental protection whiledeveloping the economy is heard everywhere.Smog especially is a common concern. Like a popular onlinepost said, air may be the only thing that is equal for everyone,despite your income or vocation. People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices, but they breathe the same air as everyone else.At a meeting on Monday, many Representatives have expressed their concerns about the air quality, too. One talked about his experience in Beijing. “After taking a taxi from the capital airport to my hotel, which took about an hour, I washed my nose and found the inside of my nose was black. We should ask ourselves this question: Why do we want to develop? It’s for living a better life. Dirty air is definitely not a better life，” he said.China needs to develop its economy and invest (投资) in hightech. Every Chinese wants a strong country. But without blue sky, clean water and safe food, the achievements in the economy will become meaningless. Space technologies are not to be developed for building a base on Mars so that one day all human beings can migrate to the red planet because they have destroyed Earth.What the public wants is a strong and beautiful China. President Hu Jintao spoke at the 18th Party Congress last November, saying that great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central government’s resolution to address the environment issue.9．The effect of smog doesn’t include________.A．the rising of PM 2.5 readingsB．more people suffering diseasesC．the increase of people’s incomeD．the increase of patients suffering acute spiratory in hospital10．Why smog has become a common concern?A．Because people have to pay higher prices.B．Because nobody can avoid it.C．Because we have to develop industry.D．Because a popular online post discussed it.11．From the last two paragraphs we can infer that________.A．hightech can completely solve the problem of pollutionB．space technologies should be developed in a large scaleC．we can move to the Mars after the earth has been destroyedD．we must protect the environment while developing economyDIn a nation with a onechild family planning policy, it’s understandable for parents to worry over whether they are petting their children. Are the children truly as fragile as sometimes made out to be?The concern has been brought into focus with the popularity of a hit reality TV series, Hunan TV’s Dad!Where Are We Going? and Zhejiang TV’s First Time in Life. In both, children as young as three have become new public figures. In the show First Time in Life, children chosen from ordinary families are given small tasks to complete by themselves；the ongoing Dad!Show centers on five celebrity fathers and their children who are forced to live a simple life in rural areas, far outside their comfort zone.Regardless of their families background, the children’s reactions to new environments have struck the public.In one episode of Dad! , the fiveyearold daughter of former Olympic diving champion Tian Liang cries and hides behind her father when they arrive at a rural village. In an episode of the other series, a young girl in Tianjin breaks down into a tearful fit after being asked by her father to go out alone to buy eggs and a pancake.In the eyes of some observers, these kids show no sense of independence, and the reason is put down to parents who are overly sheltering. But television viewers and parents were heartened when the sobbing Tianjin girl finally wiped away her tears as she returned holding the pancake. In the case of Tian’s daughter, she eventually began to take care of her younger companions and learned to seek help from people she didn’t know.The father of the Tianjin girl f elt “delightfully_shocked” and said. “She used to have to be accompanied by her mother or grandmother. Now she has the courage to do it all by herself. ”The shows have led many parents to change how they raise their children. Shanghai mother Liang Jing sa id she would try to “give some training” to her shy son, asking him to tidy up his toys. Lin Yi, a parenting expert in Beijing, said giving kids a chance to do things for themselves helps to raise their sense of achievement, which carries benefits throughout their lives.12．The children in the two programs Dad!Where Are We going? and First Time in Life are different in________.A．family background B．age groupC．personality D．popularity13．What attracts the audience’s eyes in the programs?A．What the kids’ family background is like.B．Where children’s real comfort zone is.C．How children react to new environments.D．Why those children are independent.14．It can be inferred from the underline words “delightfully shocked” that________.A．father is more important than mother in a familyB．children deserve a chance to be independentC．parents should provide a safe environmentD．the children are as fragile as parents expected15．The shows are bound to raise a wave of discussion about________.A．protecting good traditions B．the social safetyC．approaches to parenting D．the influence of TV programmesⅡ.任务型阅读How to Eat slowly to Avoid OvereatingEating slowly can help you to better understand your real hunger signals and can help you to recognize reasons for faster eating, such as emotions or simply liking the taste of a food.
