A sunflower is a sunflower. A mobile phone is a mobile phone. But can you combine the two to do something for your local environment?
As early as next year it may well be possible. When you have finished with your mobile phone you will be able to bury it in the garden or a plant pot and wait for it to flower. A biodegradable (生物可降解的) mobile phone was, this month, introduced by scientists. It is hoped that the new type of phone will encourage consumers to recycle.
Scientists have come up with a new material over the last five years. It looks like any other plastic and can be hard or soft, and able to change shape. Overtime it can also break down into the soil without giving out any toxic (有毒的) chemicals. British researchers used the new material to develop a phone cover that contains a sunflower seed. When this new type of cover turns into waste, it forms nitrates (硝酸盐). These feed the seed and help the flower grow.
Engineers have designed a small transparent (透明的) window to hold the seed. They have made sure it only grows when the phone is thrown away.
"We've only put sunflower seeds into the covers so far. But we are working with plant experts to find out which flowers would perform best. Maybe we could put roses in next time," said one scientist.
As phone technology is developing so quickly people are constantly (经常地) throwing their mobiles away. This means manufacturers are under pressure to find ways of recycling them.
Some 650 million mobile phones have been sold this year. Most of them will be thrown away within two years, adding plastic, heavy metal and chemical waste to the environment. A biodegradable cover can offer some relief for nature, according to the scientists.
"The seed is released and the flower grows in the pot so you don't have to concern yourself with the phone when you have finished using it," said Kerry Kirwan. She leads the research team, which is based at the University of Warwick in Britain.After you have finished using the new type of mobile phone, ________.
| A．the sunflower seed will come out and flower wherever you throw it |
| B．the phone cover will break down easily in the soil which you bury it in |
| C．it will be recycled by the manufactures |
| D．it can recharge itself in an environmental friendly way |
Which of the following is wrong about the cover of the new type of phone?
| A．It can provide useful fertilizer for the sunflower seed after the mobile phone breaks down. |
| B．It looks like normal plastics but it can break down. |
| C．It can serve as the storage for the sunflower seed. |
| D．It makes sure the seed only grows after the phone is thrown away. |
This type of research is done because ________.
| A．the technology that produces mobile phones is changing rapidly |
| B．consumers tend to throw away their mobile phones within two years |
| C．nobody has ever thought of recycling mobile phones |
| D．producing mobile phones uses a lot of energy, so this has become a very big problem for the environment |
We can infer from the story ________.
| A．the new type of mobile phone is already on the market |
| B．the new type of mobile phone will sell extremely well |
| C．recycling mobile phones is increasingly important to the environment |
| D．other flowers may be used in the new type of cell phone |
To extinguish (熄灭) different kinds of fires, several types of fire extinguishers have been invented. They must be ready for immediate use when fire breaks out. Most portable (手提式的) kinds operate for less than a minute, so they are useful only on small fires. The law requires ships, trains, buses and planes to carry extinguishers.
Since fuel, oxygen and heat must be present in order for fire to exist, one or more of these things must be removed or reduced to extinguish a fire. If the heat is reduced by cooling the material below a certain temperature, the fire goes out. The cooling method is the most common way to put out a fire. Water is the best cooling material because it is low in cost and easy to get.
Another method of extinguishing fire is by cutting off the oxygen. This is usually done by covering the fire with sand, steam or some other things. A blanket may be used do cover a small fire.
A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.
The method that is used to put out a fire depends upon the type of fire. Fires have been grouped in three classes. Fires in wood, paper, cloth and the like are called Class A fires. These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.If a fire breaks out on a bus, which of the follow should be ready there for you to use?
| A．Sand | B．Water | C．A blanket. | D．An extinguisher. |
To cover a small piece of burning wood with a basin in order to stop the fire is an example of .
| A．cutting off the oxygen | B．reducing the heat |
| C．removing the fuel | D．separating the fire |
In choosing how to put out a fire, we should first be clear about .
| A．when it breaks out | B．what kind it is |
| C．how it comes about | D．where it takes place |
What would the author probably discuss in the paragraph that follows?
| A．Another type of extinguishers |
| B．Another class of fires |
| C．How fires break out. |
| D．How fires can be prevented. |
The technology is great. Without it we wouldn’t have been able to put a man on the moon, explore the ocean’s depths or eat microwave sausages. Computers have revolutionized our lives and they have the power to educate and pass on knowledge. But sometimes this power can create more problems than it solves.
Every doctor has had to try their best to calm down patients who’ve come into their surgery waving an Internet print-out, convinced that they have some rare incurable disease, say, throat cancer. The truth is usually far more ordinary, though: they don’t have throat cancer, and it’s just that their throats are swollen. Being a graduate of the Internet “school” of medicine does not guarantee accurate self-health-checks.
One day Mrs. Almond came to my hospital after feeling faint at work. While I took her blood sample and tried to find out what was wrong, she said calmly, “I know what’s wrong; I’ve got throat cancer. I know there’s nothing you doctors can do about it and I’ve just got to wait until the day comes.”
As a matter of routine I ordered a chest X-ray. I looked at it and the blood results an hour later. Something wasn’t right. “Did your local doctor do an X-ray?” I asked. “Oh, I haven’t been to the doctor for years,” she replied. “I read about it on a website and the symptoms fitted, so I knew that’s what I had.”
However, some of her symptoms, like the severe cough and weight loss, didn’t fit with it—but she’d just ignored this.
I looked at the X-ray again, and more tests confirmed it wasn’t the cancer but tuberculosis (肺结核)—something that most certainly did need treating, and could be deadly. She was lucky we caught it when we did.
Mrs. Almond went pale when I explained she would have to be on treatment for the next six months to ensure that she was fully recovered. It was certainly a lesson for her. “I’m so embarrassed,” she said, shaking her head, as I explained that all the people she had come into close contact with would have to be found out and tested. She listed up to about 20, and then I went to my office to type up my notes. Unexpectedly, the computer was not working, so I had to wait until someone from the IT department came to fix it. Typical. Maybe I should have a microwave sausage while I waited?Mrs. Almond talked about her illness calmly because ______.
| A．she had purchased medicine online |
| B．she thought she knew it well |
| C．she graduated from a medical school |
| D．she had been treated by local doctors |
It was lucky for Mrs. Almond ______.
| A．to have contacted many friends |
| B．to have recovered in a short time |
| C．to have her disease identified in time |
| D．to have her assumption confirmed |
Mrs. Almond said “I’m so embarrassed” (Para. 7) because ______.
| A．she had distrusted her close friends |
| B．she had to tell the truth to the doctor |
| C．she had to refuse the doctor’s advice |
| D．she had caused unnecessary trouble |
By mentioning the breakdown of the computer, the author probably wants to prove ______.
| A．it’s a must to take a break at work |
| B．it’s vital to believe in IT experts |
| C．it’s a danger to work long hours on computers |
| D．it’s unwise to simply rely on technology |
People fell in love with Elizabeth Taylor in 1944, when she starred in National Velvet—the story of Velvet Brown, a young girl who wins the first place in a famous horse race.

As your charming child changes into a rebellious teenager, take a deep breath and have a good look at the situation before you throw up your arms in anger or distress. Your teen takes a vital step towards adulthood by way of fighting against your rules, regulations and attitudes. Moving beyond their previous dependence on parents, teachers and other adults, teens learn to make decisions, understand the consequences of their behavior and get ready to take on adult responsibilities.
The growing need for independence sits at the heart of teenage rebellion. Many teens prefer to use peers as role models and often begin to question the reasoning behind home and school boundaries as they step closer to adulthood. The physical changes involved in adolescence coincide with(与…相一致) emotional, intellectual and moral growth, points out Kids Health---all of these can affect teenagers strongly and leave them feeling at a loss and stressed. They test different types of behavior, and it’s through this testing and boundary pushing that they learn what works and what does not from their own successes and mistakes.
Changes to a teenager’s hair and clothing emphasize her growing independent tastes and highlight her inclusion in a group of friends. Her opinions may begin to differ from yours as she develops her own values, leading to potential conflicts on subjects ranging from television programs to world affairs. A teen may break family rules regarding chores, loud music and schoolwork and find herself facing unwelcome punishment as a result. These acts of rebellion normally occur from time to time rather than continuously. They give teenagers the chance to see the results of their decisions for themselves and learn when rebellion may be a mistake.
Unhealthy patterns of rebellion can include acts of rebellion that increase in frequency. Violent bursts of anger, physically and emotional destructive behavior and offensive language may indicate that your teen feels bitter hatred towards adults and authority and needs help in navigating those feelings.
