Jackie Heinricher's love affair with bamboo started in her backyard. “As a child, I remember playing among the golden bamboo my dad had planted, and when there was a slight wind, the bamboos sounded really musical.”
A fisheries biologist, Heinricher, 47, planned to work in the salmon industry in Seattle, where she lived with her husband, Guy Thornburgh, but she found it too competitive. Then her garden gave her the idea for a business: She'd planted 20 bamboo forests on their seven-acre farm.
Heinricher started Boo-Shoot Gardens in 1998. She realized early on what is just now beginning to be known to the rest of the world. It can be used to make fishing poles, skateboards, buildings, furniture, floors, and even clothing. An added bonus: Bamboo absorbs four times as much carbon dioxide as a group of hardwood trees and releases 35 percent more oxygen.
First she had to find a way to mass-produce the plants—a tough task, since bamboo flowers create seed only once every 50 to 100 years. And dividing a bamboo plant frequently kills it.
Heinricher appealed to Randy Burr, a tissue culture expert, to help her. “People kept telling us we'd never figure it out,” says Heinricher.“Others had worked on it for 27 years! I believed in what we were doing, though, so I just kept going.”
She was right to feel a sense of urgency. Bamboo forests are being rapidly used up, and a United Nations report showed that even though bamboo is highly renewable, as many as half of the world's species are threatened with dying out. Heinricher knew that bamboo could make a significant impact on carbon emissions(排放)and world economies, but only if huge numbers could be produced. And that's just what she and Burr figured out after nine years of experiments—a way to grow millions of plants. By placing cuttings in test tubes with salts, vitamins, plant hormones, and seaweed gel, they got the plants to grow and then raised them in soil in greenhouses.
Not long after it, Burr's lab hit financial difficulties. Heinricher had no experience running a tissue culture operation, but she wasn't prepared to quit. So she bought the lab.
Today Heinricher heads up a profitable multimillion-dollar company, working on species from all over the world and selling them to wholesalers(批发商). “If you want to farm bamboo, it's hard to do without the young plants, and that's what we have,” she says proudly.
What was the main problem with planting bamboo widely?

A.They didn't have enough young bamboo.
B.They were short of money and experience.
C.They didn't have a big enough farm to do it.
D.They were not understood by other people.

What does Heinricher think of bamboo?

A.Fragile and affordable.
B.Productive and flexible.
C.Useful and earth-friendly.
D.Strong and profitable.

The underlined word “renewable” in Paragraph 6 probably means “________”.

A.able to be replaced naturally
B.able to be raised difficultly
C.able to be shaped easily
D.able to be recycled conveniently

What do you learn from the passage?

A.Heinricher's love for bamboo led to her experiments in the lab.
B.Heinricher's determination helped her to succeed in her work.
C.Heinricher struggled to prevent bamboo from disappearing.
D.Heinricher finally succeeded in realizing her childhood dream.

Who are these people rushing by you on the street? More than 250 million people now call America" home" , but most of them can trace their families back to other parts of the world. If you, look at the names on shop windows, you will see that Americans come from many different lands. The idea that these people, who once were strangers to the United States,have lost the customs and cultures of their original countries and have become "Americans"is really not true. In fact, what exists in America is - more often a kind of “ side - by - side" living in which groups of people from other countries often have kept many of their own customs and habits. They join the general American society only in certain areas of their lives such as in schools,business,and sports一but they keep many of their own native customs and manners socially and at home. This “ side - by - side" living has both advantages and disadvantages. Sometimes it may cause disagreements to develop between groups whose ways of life are very different from one another. However, there are also great advantages that come from the variety of cultures brought by settlers from other lands. There is great freedom of choice among ideas ’ dress, food, and social customs in America.

The bar-tailed godwit (斑尾鷸)has just broken its own record for the world’s longest non-stop flight, including humans in planes, according to a report made by Lund University Press. The bird can fly non-stop for eight days, while the most impressive man-made airplane can only remain in the sky for 82 hours without a stop.
The bar-tailed godwit’s journey, from Alaska to New Zealand, covers over 6,835 miles. It completes this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as short as what the bar-tailed godwit travels.
One reason for the bar-tailed godwit’s success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from Lund University, says, “This figure is extremely low compared with other birds.” The bird also has a special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels fast, compared to other birds and animals.
Many questions remain about this bird record holder that never gets lost in the air. Researchers wonder whether it has an inside compass (指南针) that helps it to know the direction. Please watch how beautiful bar-tailed godwits look as they come in for a landing, along with other birds.
For the flight from Alaska to New Zealand, the bar-tailed godwit__________

A.doesn’t need to stop to eat

Are you fond of tomatoes? Bunol, a town in Spain, held its yearly tomato festival on the last Wednesday of August. Thousands and thousands of people made their way from all corners of the world to fight in it, the world’s biggest food fight. Tons of fully-grown tomatoes were thrown in the streets.
No one knows exactly how this event started. Maybe it came from a local food fight between friends, or a joke that was played on a bad musician.
On Wednesday, at 11am, the fight began. A cannon(大炮) shot was fired to start the fight. At first, people fought one another, but slowly they began to fight in groups. After exactly one hour, the fight ended when the cannon shot was fired once more. At this point, no more tomatoes could be thrown.
Those who attend this event are encouraged to wear protective glasses. And they must press the tomatoes before throwing so that they won’t hurt others. Another rule is that no one is allowed to take anything — such as a glass bottle — into the fight. Although it is forbidden to tear(扯破) another person’s clothing, the crowd seems to tear the shirt of any clothed person, whether they are men or women.
Fire trucks are used to clean the streets after the fight with water provided from a Roman channel (海峡). The government seems more concerned with cleaning up the town than the visitors, and people go to the Bunol River for a wash.
What do we know about the tomato fight?

A.Nobody knows how it really started.
B.Only people from Spain can take part in it.
C.It is held on the first Wednesday of August.
D.Green tomatoes can be used in the fight.
