Retired nurse Sue Collins was just beginning the second length of her local pool when her morning swim suddenly became anything but a pleasure.
Two months ago Sue, 69, who has never suffered from asthma or any other breathing problem in the past, suddenly found herself hard for breath.
“I felt as if my throat and oesophagus (食道) were closing up,” says Sue.
Sue is convinced the problem is related to the indoor swimming baths. “I spend half the year in Turkey and swim every day outside in a pool or the sea there and never have this problem,” she says.
She may be right, because although a trip to the pool is the perfect exercise for many, the chlorine (氯气) used to keep the water free from germs can lead to problems.
But in most cases it’s not the chlorine that causes problems, but the by-products formed when chlorine interacts with other substances — and this is mostly due to people not showering before they enter the pool.
“This then poisons the water for them and for others,” says Dr. Hull. “The chlorine interacts with sweat and urine(尿素) on the skin and forms by-products called chloramines that float above the surface as a gaseous solution that can be inhaled in.”
Chloramines are heavier than air so hang over the water where they are easily breathed in. Some believe they may cause lung disorders. A Swedish study in 2013 examining the health of 146 workers at 46 indoor pools found that 17 per cent had airway trouble at work — but no problems at home.
As Dr. Hull says: ‘People need to remember that showering isn’t just for them. It is for the greater good.’
1.Where did Sue suddenly suffer from asthma?
A. In an outdoor swimming pool. B. In the sea.
C. In an indoor swimming pool. D. At home.
2.Why should we put chlorine into the water of the pool?
A. To keep the water warm. B. To kill the germs in the water.
C. To make the people easy to breathe. D. To stop the possibility of asthma.
3.Taking a shower before swimming in the pool is to ________.
A. stop the interaction between the chlorine and sweat and urine on the skin
B. make the swimmer feel comfortable
C. obey the rule of the pool
D. stop people from breathing in the chlorine
4.What’s the purpose of the passage?
A. To show how to avoid asthma.
B. To explain chloramines’s usage.
C. To help people cure asthma.
D. To tell people why to take a shower before swimming in a pool.

I live in a city, and I like quiet life. I hate nosy (爱管闲事的) neighbors but it’s very unlucky that I had one for myself. They moved in a couple of months ago and although I never felt that they were a strange family, I’ve always hated the way they get “too close” to me, my house, my garden
, and even my garbage cans.
One day, my neighbors were mowing their lawn (草坪). My garbage cans were near their lawn. For some strange reason, I found the wife looking through my garbage cans. I felt angry but since they were from a different culture, I thought that maybe it was “normal” from their ideas.
That afternoon, the couple knocked on my front door. When I opened, they gave me a plastic bag. Inside were my old daily bills, credit cards and bank statements, and an old birthday card that my old uncle sent. They said that they were returning them to me because these documents contained very private information that may be used by others.
I’ve heard of it before. I asked them how those documents can be used by others and they started telling me their very own experience, which forced them to leave their home and move next door to us. The wife told me that she never destroyed the bills. They also had a “nosy neighbour” who looked through their garbage cans which they actually thought was pretty strange. Little did they know that this “nosy neighbor” was collecting their personal information from their rubbish. Then all their money was taken out from the bank by their neighbor.
It was a very painful experience for all of them and they wanted to leave it all behind so they left. I was very thankful. They were not nosy neighbors. They simply didn’t want us to experience the same thing that they did.

A. they no longer had money to live in their former home
B. their personal documents were used by their former neighbor
C. they didn’t want to live in such a noisy home as before

It is generally believed that we are getting cleaned when we step under a shower. We are, but we’re also giving a home to lots of tiny little creatures we didn’t even know about. A shower head carries thousands of bacteria called Mycobacterium. These can cause problems like coughs and tiredness, and a general feeling of being sick. When you turn on the water, the bacteria go from the shower head onto and into your body.
This is a finding of Norman R. Pace and his team at the University of Colorado, in the US. Pace's team looked at 45 shower heads in nine American cities. They discovered that 30 percent of them had large amounts of flying Mycobacterium.
But Pace said that they pose few threats to the health. Only those with a weak immune system might need to worry．He told the New York Times that the bacteria are not as unpleasant as might be thought. He said that having a shower is no more dangerous than anything else we do in the morning.
But for those who feel sick about the idea of all those microorganisms (微生物), he had some advice. Let the water run for 30 seconds before getting into the shower. Why? The number of bacteria is smaller than that when the water is just turned on. If that seems like a waste of water, he added that you could also change your shower head every few months.
However, Pace had good news too. He has also been testing the air in US subways. Apart from iron particles (粒子), which are ground off the track by the wheels of trains, subway air is fresh. The reason is that a train’s movement pumps fresh outdoor air into the tunnels.
1.From the finding of Norman R. Pace, after taking a shower, we might cough or feel tired because ________.
A. it’s easy to get a cold when taking a bath
B. the shower head carries many bacteria causing illness
C. we don’t get cleaned while showering
D. we don’t get a weak immune system
2.We can learn from the third paragraph that ________.
A. the bacteria always threat people’s health
B. there is no need to fear microorganisms for people with strong immune system.
C. the bacteria always threat people’s health when people have a shower
D. it is better to do some exercise in the morning than have a shower.
3.What contributes to fresh air in US subways?
A. The train’s movement. B. Iron particles.
C. Train wheels. D. Air conditioners on the trains.

When I was two years old, I was diagnosed with a sensorineural (感觉神经) hearing loss. My mother cried when she found out—she wanted her son to be happy and able to experience everything life had to offer. I went to a special playgroup twice a week where a nurse discovered I had taught myself to read. I then attended a school for the deaf from age three to six.
I remember looking around the room there. People talked and signed to each other. I had a best friend and I did very well in class. But I told my mother that I wanted to go to the regular school with hearing people, because I felt more like a hearing person than a hearing-impaired (听力受损) one. I didn’t even use sign language! I lip-read and listened with my hearing aids. After visiting a public school for a day, my mother agreed to let me go. Needless to say, I have functioned very well.
Many people don’t even know I am hearing-impaired until they see my hearing aids. My girlfriend often forgets that I have any problem, and I feel fortunate that she does not look down upon people like me. The only problem I have with this hearing loss is that some people discriminate against me. The fact is that I am just as normal as anyone else. The only differences are that others need to speak up, and I have some help from my hearing aids.
The next time you see hearing-impaired people, don’t feel sorry for them—that just gives them an excuse to victimize themselves and hurt their own potential. Instead, encourage them and tell them that a handicap（缺陷）only hurts a person if he or she lets it.
1.Which is TRUE about the author when he was 5?
A. He was diagnosed with hearing loss.
B. He stayed at home with his mother.
C. He attended a school for the deaf.
D. He went to a special playgroup.
2.Why did the author want to attend the regular school？
A. He had few friends at the school.
B. He even didn’t know sign language.
C. He found it hard to fit in with his classmates.
D. He didn’t believe his handicap was a big problem.
3.What was the author’s problem at the regular school?
A. He couldn’t catch up with others.
B. Some people looked down upon him.
C. His girlfriend discriminated against him.
D. He performed poorly with hearing aids.
4.What does the underlined part in the last paragraph mean?
A. The disabled should regard themselves as normal.
B. If a person is handicapped, he will hurt himself.
C. A normal person shouldn’t hurt the handicapped.
D. A disabled person should be well treated.

In a speech this week to the Institute of Civil Engineering, the Prime Minister, David Cameron, made clear his support for wind energy. He focused on some of the many advantages of developing the industry.
Let’s examine those reasons. It is an abundant, clean and sustainable source of energy, reducing our dependence on expensive fossil fuel imports, increasingly from politically unstable parts of the globe. Let’s not forget that Russia turned off the gas supply to Europe in 2006.
More recently, we have all felt the pain this winter, when international gas prices soared by 40% compared to last year. Should we carry on exposing ourselves to the instability（不稳定） of global energy prices and the unpredictability of global events, or should we recognize the value of taking control of our energy supply?
As for the economic opportunities, over the last decade wind energy has attracted $5 billion in investment(投资) to the UK and is set to go above $50 billion by 2020. Look at the companies queuing up to build wind turbine (涡轮) factories in the UK, such as Siemens and Vestas. Examine the number of people employed in the wind industry in the UK—nearly 12000, now with nearly 90000 jobs by 2021.
The UK is already the global leader in wind power, with greater ability than anywhere else in the world—enough to supply more than a million homes with electricity all year round—and the government is calling for an increase by eight times in the amount of wind turbines installed by 2020, which the industry can achieve as long as it gets the right level of support from ministers. In return, as well as bring the environmental benefits of clean energy, the wind industry is committed to save consumers a lot of money.
1.What can we know from Paragraph 4?
A. Many job opportunities are created by wind industry.
B. The UK would not accept many companies’ investment.
C. Over the last ten years the UK has attracted little investment.
D. Other industries are less important than wind industry.
2.The writer uses the example of Russia to prove that ________.
A. international gas price is not always stable
B. there exists the unpredictability of global events
C. there are conflicts between Europe and Russia
D. every nation is badly in need of gas
3.What is the most important thing for the government to achieve its goal by 2020?
A. Attracting more investment.
B. Getting enough support from ministers.
C. Improving the technology a lot.
D. Listing the advantages of wind power to the public.
4.What is correct for the UK facing the problem of energy?
A. The UK should increase its dependence on fossil fuel imports.
B. It’s OK to carry on exposing itself to the instable energy prices.
C. The UK should believe the global events can be predictable.
D. The government has recognized the necessity of controlling its energy supply and did better.
