题目内容
In Asia, there are special competitions where kites have complex designs and are fitted with instruments that make musical sounds as the wind blows through them. Although all kites have a similar structure (结构), they are widely different in size and shape. Kite-fighting competitions are also held, in which competitions us their kites to attack and bring down their opponents’(对手)kites or cut their strings(线).
For more than 15 years, the Big Wind Kite Factory has been giving kite-making and kite flying classes for the children on an island in Hawaii. In its kite-making lessons, students can make kites in as little as 20 minutes! Children as young as four years old can learn how to fly a kite. Jonathan Socher and his wife Daphne started the kite factory in 1980. Their kites are made of nylon(尼龙).Their designs are Hawaiian themes created by Daphne. The designs are cut out of the nylon with a hot knife that seals the edges and then fastened directly onto the kite.
The kite that is used to give lessons is regular diamond kite with a rainbow pattern. The difference between this kite and the ones they make during the lessons is that it is a two-string controllable kite. Big Wind employees fly the kite and for a few minutes show students how pulling on one line and then on the other controls the direction the kite goes in. Then the controls are given to the students.
Jonathan insists that it is not necessary to make a huge impressive kite to have fun making and flying kites. Even the simplest structure can work, and can give hours of fun. Go on, give it a try!

Bamboo (竹子) is one of nature’s most surprising plants. Many people call this plant a tree, but it is a kind of grass.
Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1, 000 kinds of bamboo.
Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimeters wide while others may grow to more than 30 centimeters across. This plant also comes in different colors, from yellow to black to green.
Bamboo has been used to make many things such as hats and kitchen tools. Because it is strong, bamboo is also used to build buildings.
Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting new buildings and bridges while they are being built.
In Africa, poor farmers are taught how to find water using bamboo. These African countries need cheap way to find water because they have no money, and their fields often die from no rain and no water. Bamboo pipes (管子) help poor farmers bring water to their thirsty fields without spending a lot of money.
【小题1】How is bamboo like grass?
A.It grows quickly. | B.It’s wood. |
C.It is easy to cut. | D.It is very thin. |
A.in China | B.in Europe |
C.on mountains | D.in Africa |
A.It is cheap. | B.It has different colors. |
C.It is strong. | D.It has been used by Asians. |
A.a short time | B.about 100 years |

Crossroads International
1. How does Crossroads work?
Crossroads is a resource network. We take goods Hong Kong doesn’t want and give them to people who badly need them. We collect those goods and give them out in the welfare(福利)center in Hong Kong, Mainland China, elsewhere in Asia, Eastern Europe and Africa. 1
2. Who do we help?
2 They are grass-root groups who have seen a need and tried to meet it. They can’t get the job done without back-up, though, so our task is to help them do their task. Our warehouse is full of goods, from computers to high chairs, clothing to books, stationery to medical provision, cupboards to dining sets. They send us a list of their needs and we try to match it with the resource we have in stock.
3. 3
Crossroads itself also operates on a low budget. We do not buy the goods we send. They are donated. 4 Nobody in our organization receives a salary. Even our full-time staff work on a voluntary basis.
Those that donate goods and services:
●Factories ●Manufacturers
●Hospitals ●Hotels
●Educational Institutions ●Householders
●Transport Companies ●Offices
●Other Charities
5 While we receive large quantities of goods and there is never a short supply of requests for them, we are always in need of hands to help sort and prepare them for shipping.
A.One resource that we are always in need of is people. |
B.So Crossroads is just that: a Crossroads between need and resource. |
C.What can I do? |
D.The welfare agencies we help do not run on large budgets. |
F. All volunteer work is done at our warehouse.
G.. Similarly, rather than raising funds for freight (货运), we ask transport companies to donate their services.
When people first walked across the Bering Land Bridge thousands of years ago, dogs were by their sides, according to a study published in the journal Science.
Robert Wayne of the University of California, Los Angeles, and Jennifer Leonard of the Smithsonian Institute, used DNA material—some of it unearthed by miners in Alaska—to conclude that today’s domestic dog originated in Asia and accompanied the first humans to the New World about 10,000 to 15,000 years ago. Wayne suggests that man’s best friend may have enabled the tough journey from Asia into North America. “Dogs may have been the reason people made it across the land bridge,” said Wayne. “They can pull things, carry things, defend you from fierce animals, and they’re useful to eat.”
Researchers have agreed that today’s dog is the result of the domestication(驯化) of wolves thousands of years ago. Before this recent study, a common thought about the precise origin of North America’s domestic dog was that Natives domesticated local wolves, the descendents(后代) of which now live with people in Alaska, Canada, and the Lower 48.
Dog remains from a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost(永冻层) until Fairbanks miners uncovered them in the 1920s. The miners donated the preserved bones to the American Museum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A.D., before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of “pure native American dogs,” Leonard said. The DNA of the Fairbanks dogs would also expose whether they were the descendents of wolves from North America.
Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens(标本) from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America, the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge.
Leonard and Wayne’s study suggests that dogs joined the first humans that made the adventure across the Bering Land Bridge to slowly populate the Americas. Wayne thinks the dogs that made the trip must have provided some excellent service to their human companions or they would not have been brought along. “Dogs must have been useful because they were expensive to keep,” Wayne said. “They didn’t feed on mice; they fed on meat, which was a very guarded resource.”
