When you buy fresh-cut flowers, do you think about where they came from？You might think they were grown somewhere nearby. The reality, though, is that the cut flower trade is increasingly International. Today, thanks to airplanes and high-tech cooling systems, even the most delicate flower be exported and sold thousands of kilometers away from where it was grown.
The Netherlands handles about 60 percent of the world’s cut flowers. And its auction houses（拍卖行）are very large---Aalsmeer, near Amsterdam, is auction house in the sense that Tokyo is a city, or Everest a mountain. About 120 soccer fields would fill its main building. Nineteen million flowers are sold here on an average day.
The Netherlands is also a world leader in developing new flower varieties. Dutch companies and the government invest a great amount of money in flower research. Their scientists look for ways to lengthen a flower’s vase life, to strengthen flowers to prevent them from being damaged while traveling, and also to strengthen the natural fragrance of the flowers.
There are also many other places with a better climate for growing flowers, and the climate of Ecuador is almost perfect. With predictable rainy periods and 12 hours of sunlight each day, Ecuador’s roses are famous for their large heads and long, straight stems（茎）. Every year, Ecuador sells about 500 million flowers to the U.S. alone. The industry has brought employment opportunities and a stronger economy to the country. “My family has TV now. There are radios.” says Yolanda Quishpe, 20, who picked roses for four years.
To others, the increasingly international nature of the flower trade is very bad news. In recent years local growers in the U.S. faced huge competition from international flower companies, and many lost their businesses. Lina Hale, an independent rose grower said her father had predicted the situation in the 1980s. “I see a train coming down the track,” he warned her, “and it’s coming straight towards us.”

When you think about math, you probably don’t think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.
People who solve crimes look for patterns that might reveal(揭示) the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer to where they live, simply because it’s easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect(嫌疑犯) who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.
But Mike O’Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal’s home base by combining these patterns with a city’s layout(布局) and historical crime records.
The records of past crimes contain geographical information and can reveal easy targets — that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections are. O’Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal’s patterns change with age. It’s been shown, for example, that the younger the criminal, the closer to home the crime.
Other computer programmers have worked on similar software, but O’Leary’s uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country.
The program is just one way to use math to fight crime. O’Leary says that criminology — the study of crime and criminals — contains a lot of good math problems. “I feel like I’m in a gold mine and I’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”
1.
To find criminals, police usually ______.
A. focus on where crimes take place B. seek help from local people
C. depend on new mathematical tools D. check who are on the crime scene
2.
O’Leary is writing a computer program that ______.
A. uses math to increase the speed of calculation
B. tells the identity of a criminal in a certain area
C. shows changes in criminals’ patterns
D. provides the crime records of a given city
3.
By “I’m the only one who knows what gold looks like”, O’Leary means that he ______.
A. is better at finding gold than others
B. is the only one who uses math to make money
C. knows more criminals than other mathematicians
D. knows best how to use math to help solve crimes
4.
What is the main idea of the text?
A. Criminals live near where crimes occur.
B. Math could help police find criminals.
C. Crime records could be used to fight crime.
D. Computer software works in preventing crimes.

Good health is the most valuable thing in the world. When you’ve got it, you never think about it. When you haven’t got it, you think about it all the time. Our biggest enemies are not terrible diseases and so on. We are our own biggest enemies because we sometimes destroy our own good health. Some of us eat too much, drink too much and smoke too much. And though our reason tells us we should control ourselves, we find it difficult. The fact is that most human beings need stimulation (刺激). Who doesn’t enjoy a drink after a busy day? Only a smoker knows the pleasure of a cigarette with a cup of coffee.
The danger is when these innocent pleasures run our lives and so destroy our health. When you find yourself eating between meals or eating too much rich food, when you can only keep yourself going by taking frequent (频繁的) drinks or by smoking one cigarette after another, then it’s time to stop and think what you might be doing to yourself. The funny thing is that when we don’t control ourselves, simple pleasures are no longer simple pleasures.
All right, I know what you’re thinking. You’re probably saying, “It’s easy to say, but I can’t help myself. I need that extra bit of food, that extra drink, that extra cigarette. Life has so many pleasures that I can’t do without them.” But I’m saying you can help yourself. Not only that, you must help yourself. Because if you don’t help yourself, no one else can. So be your own best friend.
1.The underlined word “innocent”(in Paragraph 2) means ________.
A. not having done something wrong
B. exciting or cheering
C. not having much experience
D. not expected to cause harm
2.This passage is mainly about _______.
A. terrible diseases and so on
B. enjoying pleasures after a busy day
C. the difficulty of controlling ourselves
D. the danger of too much drinking, smoking and eating
3.“I can’t help myself” means ____________.
A. I can’t do it myself
B. I must ask someone to help
C. I can’t control myself
D. Do help me, please

Where do you find out about the world’s longest walk? The world's tallest man? The world's oldest woman? You know the answer, of course. It is the Guinness Book of World Records. How would people find such unusual facts without this book?
Guinness Book did not exist until 1951. Here is what happened. The managing director of Guinness Brewery was a curious man. He wanted answers to some questions about records. For example, he wanted to know what was the fastest flying game bird in Europe. But he was frustrated. There was no book to answer questions like this.
The director, Sir Hugh Beaver, contacted the McWhirter twins. They were brothers who owned a research agency. He asked them to put together a new reference book. It would in
clude all kinds of unusual records. The brothers quickly accepted. The first edition of their book was published in 1955. Soon the Guinness Book of World Records was a best seller. It has sold more copies than any book except the Bible. A new edition is published every year.Where do all the book's records come from? They are a combination of things like natural wonders, sports records, and stunts(特技) (How many people would push an egg with their noses if they weren’t trying to get to the book?).
But the editors try to keep things honest. All records must be verified by an investigator. Only then are they printed.The Guinness Book is a big business. It is published in dozens of languages. There are TV shows and museums. It is proof of how interested people are in strange pieces of information.
1.The passage is mostly about _____.

List all the reasons why you want to quit. Every night before going to bed, repeat one of the reasons 10 times.
Decide positively that you want to quit. Try to avoid negative thoughts about how difficult it might be. Develop strong personal reasons as well as your health and responsibility to others. For example, think of all the time you waste taking cigarette breaks, rushing out to buy a pack, hunting a light, etc. Set a date for quitting — perhaps a special day like your birthday, a holiday.
