Most parents love the Internet and want their kids to use it. But a new survey in America finds almost as many also fear the online world—especially social networking sites such as My Space—and worry their kids will get in trouble with people they meet.

“The parents see the web’s incredible potential(可能性), and they know their kids have to be there.” says James Steyer, CEO of Common Sense Media, which released results from a survey that looked into parental attitudes toward the Internet. “It is also what they are scared of most.”

The study was conducted online May 5-10 by Insight Research Group. It says 80% of parents are concerned about kids meeting bad people online. That’s because young people who largely have grown up with the Net think of it as a social outlet(出口), say the researchers. To young people, the benefits of giving out some personal information to reach out to friends outweigh the risks. And the study shows they are so comfortable with the medium that 78% have a personal website or blog.

Parents also recognize the importance of the Internet. The survey shows 91% think the Net helps their children explore their passions, and 77% think the Internet is one of the most valuable education tools teens have. But 88% think it’s important to know what their kids are doing online.

Findings suggest both parents and teens need more education about using online media, Steyer says.

Internet safety has become an increasing concern for parents in America. Organizations like the Non-profit Common Sense have been trying to reach and help parents pay attention to the problem.

There are many superstitions(迷信) in Britain, but one of the most widelyheld is that it is unlucky to walk under a ladder—even if it means stepping off the pavement into a busy street!

①Walking under a ladder

If you must walk under a ladder you can avoid bad luck by crossing your fingers and keeping them crossed until you've seen a dog. Alternatively, you must lick your finger and make a cross on the toe of your shoe, and not look again at the shoe until the mark has dried.

Anyone opening an umbrella indoors in fine weather is unpopular, as it inevitably brings rain!

③Number 13

The number 13 is said to be unlucky for some, and when the 13th day of the month falls on a Friday, anyone wishing to avoid an inauspicious event had better stay indoors.

Bamboo is one of the 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 recorded one bamboo plant that grew almost 1.5 meters in 24 hours! Bamboo grows almost everywhere in the world except Europe. There are more than 1,000 kinds of bamboo that grow around the world on both mountains and plains.

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.

Many Asian countries have been using bamboo for hundreds of years. They often use bamboo for building new buildings. As a matter of fact, the cables(绳索) that hold up the hanging bridge across the Min River in Sichuan are made of bamboo. The bridge has been in use for more than 1,000 years, and is still holding strong.

In Africa, engineers are teaching poor farmers how to find water using bamboo. These African countries need cheap ways to find water because they have no money, and their fields often die from no rain and no water. It seems that bamboo is one of the best things they can use. Bamboo pipes and drills(钻) can help to make the poor thirsty fields to be watered.

1.How is bamboo like grass?

A．It is thin and easy to cut.                  B．It grows everywhere.

C．It grows quickly after its cut short.           D．It is short and green.

2.The underlined sentence “while others may grow to more than 30 centimeters across.” means “Some other bamboo plants may grow to be very _______.”

A．short             B．strong            C．thick             D．tall

3.From the text we know ______.

A．most people call bamboo plant trees

B．a bamboo plant may grow 4.5 meters in three days

Hummingbirds (蜂鸟) are one of nature’s most energetic fliers and the only birds to hover in the air by relying on their strength alone.

Now scientists have found that it is the ratio (比值) of the bird’s wing length to its width that makes them so efficient. The discovery is helping experts compete with 42 million years of natural selection to build helicopters that are increasingly efficient.

David Lentink, an assistant professor at Stanford University in California, tested wings from 12 different species of hummingbirds, which he sourced from museums. He placed them on a machine used to test the aerodynamics (气力学) of the helicopter blades (桨叶). Professor Lentink’s team used the same machine to test the blades from an advanced micro-helicopter used by the UK’s army. They found that the micro-helicopter’s blades are as efficient at hovering as the average hummingbirds.

But while the micro-helicopter’s blades kept pace with the average hummingbird wings, they could not keep up with the most efficient hummingbird’s wing. The wings of Anna’s hummingbird were found to be about 27 percent more efficient than the man-made micro- helicopter’s blades.

While Professor Lentink wasn’t surprised at nature’s superiority, he said that helicopter blades have come a long way. “The technology is at the level of an average hummingbird,” he said. “A helicopter is really the most efficient hovering device that we can build. The best hummingbirds are still better, but I think it’s amazing that we’re getting closer. It’s not easy to match their performance, but if we build better wings with better shapes, we might match hummingbirds.”

Professor Lentink said that we don’t know how hummingbirds maintain their flight in a strong wind, how they navigate (确定方向) through branches, or how they change direction so quickly. He thinks that great steps could be made by studying wing aspect ratios—the ratio of wing length to wing width. Understanding these abilities and characteristics could be a benefit for robotics and will be the focus of future experiments.

1.What did the scientists find about hummingbirds?

A. Their wings are long and wide.

B. They can hover in the air for a long time.

C. The ratio of their wing length to wing width is very important.

D. They are the most energetic flier in nature.

2.Which is the right order of Professor Lentink’s research?

① Tested wings from different species of hummingbirds.

② Got resources from museums.

③ Analyzed the results and drew a conclusion.

④ Tested the blades from a micro-helicopter.

A. ①②③④　　 B. ②①③④　　 C. ②④①③　　 D. ②①④③

3.According to Professor Lentink, what will be the focus of future experiments?

A. To know how hummingbirds can fly in a strong wind.

B. To know how hummingbirds change direction so quickly.

C. To develop a new kind of helicopter.

D. To study the secrets of hummingbirds.
