Stop. Listen! What do you hear? You may hear many different sounds. Some of those sounds may be noise. Noise is a loud or unwanted sound.
Noise can be caused by many kinds of machines, such as motorcycles, jet planes, farm tractors(拖拉机), rock music is also noise.
What happens to people who live near noisy machines or use them over a period of time? Doctors have found that these people have trouble in sleeping. But, most important, constant(不断的) loud noise can cause a loss of hearing.

“Can I see my baby?” asked the happy new mother. When the baby was in her arms, she couldn’t believe her eyes. The baby was born without ears.
Time proved that the baby’s hearing was perfect though he had no ears. He got on well with his classmates. But one day, he said to his mother, tears in his eyes, “A big boy called me a freak(畸形物).”

You can't always predict(预测)a heavy rain or remember your umbrella. But designer Belyaev doesn't think that forgetting to check the weather forecast before going out should cause you to get wet. That's why he created Lampbrella, a lamp post(柱)with its own rain-sensing(感应)umbrella.
The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be fit to have a canopy(伞篷) built into a street lamp,” he said.
The Lampbrella is a post-looking street lamp fitted with an umbrella canopy. It has a built-in electric machine which can open or close the umbrella. Sensors(传感器) then make sure that the umbrella offers walkers shelter(遮蔽) whenever it starts raining.
Besides the rain sensor, there's also a 360° moving sensor on the street lamp which finds whether anyone is using the Lampbrella. After three minutes of not being used the canopy is closed.
According to the designer, the Lampbrella would move at a rather low speed, in order not to hurt the walkers. Besides, it would be fixed on the ground to protect from possible lightning strike. Each Lampbrella would offer enough shelter for several people. Being fixed at 2 meters off the ground, it would only be a danger for the tallest of walkers.
While there are no plans to take the Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and believes that his creation could be fixed on any street where a lot of people walk but there are no canopies to provide shelter.
. What does the underlined word “forecast” mean in Chinese?
A. 预报 B. 情况 C. 查询
. For what purpose did Belyaev create the Lampbrella?
A. To remind people to take an umbrella.
B. To check the weather forecast.
C. To protect people from the rain.
Which of the following shows how the Lampbrella works?
machine sensors
A. B. C.
. Which of the following is NOT true according to the passage?
A. His creation was inspired by an experience from Belyaev's words in Paragraph 2.
B. Paragraph 5 mainly tell us about the Lampbrella’s safety.
C. The Lampbrella will be put into immediate production.
The best title for this passage should be _____.
A. THE USE OF THE LAMPBRELLA
B. HOW TO PREVENT RAIN
C. THE NEW INVENTION-LAMPBRELLA

We sometimes have to meet some difficulties that we never expect, but we should develop a positive attitude to life. Keeping a positive attitude isn't always easy, especially when we are going through a difficult time in our life. However, we know, only when we take a positive attitude, can we overcome the difficulties.
On July 23rd, 1993, Wang Jiapeng lost his legs when his plane crashed. Wang was only 12 years old. He felt he was the unluckiest person in the world. When he saw students with their schoolbags on their backs, the sound of his wheelchair made him sick. Wang’s mother took him to a special hospital in Beijing. She looked after him in the daytime and worked at night to make money. But after two years,
Wang was still not able to leave the hospital. Wang’s mother became too tired to go on and one day she herself became a hospital patient! One morning she woke up and saw her son holding breakfast for her. Wang’s trip to the food shop was his first time outside the hospital in two years. The five-minute walk took him thirty minutes.
But he was finally able to make an important decision. He didn’t care how other people looked at him. He had to learn to do things himself.
For the next few years, Wang taught himself all his middle school subjects in the hospital and five years after the accident, he won a chance to study in a college in Norway. Wang learned to drive, go rock climbing and ski. He even won two gold medals for skiing in an international skiing competition.
“You are what you think you are,” said Wang. “If you think you’re disabled, you are. If you don’t think so, you aren’t.”
So we know that if you can keep a positive attitude, even when things aren't going well in your life, you are the true winner of life.
