While it may seem like everyone surfs the web these days, there is fine line between casually checking your social media pages and having a full blown Internet addiction. If you fear that you may lose interest in other aspects of your life because you prefer to be on the Internet, you may be on your way to an Internet addiction.
Admit you are at risk of an addiction.
More and more people in the world are becoming addicted to the Internet. You are not the only one with this problem; it is becoming more and more common and more and more well known. .
Set aside limited time for computer use.
Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you see every day. Try keeping the lid closed when you are not using it; If you have a desktop PC, try not to go near it or put something over it like a sheet.
Call people instead of sending instant messages or texts.
If you are free on weekends, call friends and ask them to go outside. This will distract you from the computer.
Use an alarm clock or timer.
Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and make sure that you get off the computer when the time is up. Alternatively create a shutdown timer on your desktop. .

Is it possible to beat high blood pressure without drugs? The answer is “yes”, according to the researchers at Johns Hopkins and three other medical centers. After a study of 800 persons with high blood pressure, they found that after 6 months, those devoted to weight loss, exercise and eating a low-salt, low-fat food lost about 13 pounds and became fitter. Plus, 35% of them dropped into the “normal” category(范畴). This week, Dr. Alan Duckworth will tell you how these people reduce their blood pressure to a level similar to what's achieved with Hypertension(高血压) drugs.

【题目】Bendable wings covered with overlapping (重叠部分) pieces looking like fish scales could be used to build more controllable, fuelefficient aircraft, a new study finds.

Nowadays, conventional aircraft typically rely on ailerons (副翼) to help control the way the planes tilt (倾斜) as they fly. However, when the Wright brothers flew the first airplane, Flyer 1, over a century ago, they used no ailerons but wires that pulled and stretched the woodandcanvas wings, to control the plane.

“Scientists have long sought to develop aircraft that can change their wings during flight, just as birds can. However, most previous attempts have failed because they relied on heavy mechanical control structures within the wings. These structures were also complex and unreliable,” said Neil Gershenfeld, a physicist and director of the Centre for Bits and Atoms at MIT.

The new wing consists of a system of tiny, strong and lightweight modules (组件). The shape of the wing can be changed uniformly along its length using two small motors, which apply a twisting pressure to each wingtip. These wings are covered in “skins” of overlapping strips of flexible material like fish scales. These strips move across each other as the wings change themselves, providing a smooth outer surface, the researchers explained.

Wind tunnel tests of these wings showed that they at least matched the aerodynamic (气动) properties of conventional wings, at about onetenth the weight. “Initial tests using remotely piloted aircraft made with these wings have shown great promise,” said Benjamin Jenett, a graduate student at the Centre for Bits and Atoms at MIT.

The new modular structures the scientists developed could be manufactured quickly in mass quantities and then installed by teams of small robots. These modular structures also can be disassembled more easily, making repairs simpler.

“Still, the first aircraft built using this strategy will not be a passenger jet,” Gershenfeld said. “Instead, the technology will likely first be tested on unmanned aircrafts, leading to aircrafts flying for a long time, to help deliver Internet access or medicine to remote villages.”

1Why is the Wright brothers' airplane mentioned in the text?

A. To show the history of aircrafts.

B. To show the development of wings.

C. To show the need to improve planes.

D. To show the structure of conventional planes.

2What makes planes fly like birds when they tilt?

A. Their ailerons. B. Wires and pulleys.

C. Changeable wings. D. Mechanical control structures.

3What is Paragraph 4 mainly about?

A. The shape of the new wings.

B. The purpose of the overlapping strips.

C. The working principle of the new wings.

D. The result of windtunnel tests of these wings.

4What does the underlined word “disassemble” mean in Paragraph 6?

A. Replace. B. Analyze.

C. Put away. D. Take apart.
