Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others.

The first is called the “tank test”. A modern airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构) of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger.

The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot’s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers.

By doing the “tank test”, the engineers can find out ___________.

A. the pressure inside and outside the plane               

B. the strength of the plane structure

C. the amount of air in the plane                              

D. the power of the airplane engines

What will happen to the plane under the “tank test”?

A. It will be broken.                                              

B. It will be made stronger.

C. It will be filled with water.                                         

D. It will be tested by pilots.

According to the text, why are test flights most dangerous?

A. The engines may be damaged.               

B. The pilot may lose control of the plane.

C. The plane may explode in the air.           

D. Too much air may get into the plane.

What might be the most suitable title for the text?

A. Two Important Tests on Airplanes                

B. The Danger of Testing Airplanes

C. The Importance of Flying Safely                  

D. How Airplanes Are Made and Tested

The Maum Sin Yong School says that they are the first in Colorado and the one of only two schools in the US to teach martial arts (武术) to students with mental diseases.

    “They do everything that our regular classes do,” says Rob Hansen, Tae Kwon Do instructor. Hansen teaches the kids how to punch (拳打), kick, and block along with the values of the Korean martial arts. He says that they also learn confidence and how to improve their motor skills. “They’ve learned focus, just to be able to pick one item and pay attention to it.”

    “Tae Kwon Do is pretty fun,” says Christina Hinkle. She was born with Down syndrome (唐氏综合症) and says she never wants to miss class. “Well, how come? It’s pretty fun.”

    “Ever since she saw Karate Kid, she’s been running around the house, doing kicks and punches,” says Peggy Hinkle, Christina’s mother. Peggy says that her daughter processes information slowly and taking Tae Kwon Do lessons has helped her in all parts of her life. “It gives her a chance to be a regular kid.”

    Wednesday’s class is not a normal class. Instead, it’s a day that all the students have been waiting for. “Today is actually the first day, and I’m actually going to be able to test these guys,” says Hansen. The students would receive their White Belts. However, in order to receive their belts, the students must show off their skills in front of a group of Black Belts.

    “Nervous? No way. I’m so excited,” says Christina just before she displayed what she has learned over the past few months. She and the other students also answered questions about the history of Tae Kwon Do, as well as its philosophy (哲学).

    “To me, it’s just really important for them to actively see that they are learning something,” says Hansen. “That they actually are able to be rewarded for everything that they’ve done in this class.” All the students passed. They received their White Belts.

    “To see the joy in her face was very rewarding,” says Peggy. She videotaped the whole test and hugged her daughter telling her that she’s proud. “Christina feels like she could do anything,” she says.

Christina says that her next goal is to keep working on her skills so she can move up to a Gold Belt. She says, “Oh, my God, I can’t believe I got the first rank.”

The purpose of teaching the students with mental disease Tae Kwon Do is _______.

A. to help them gain confidence and be skilled at concentration

B. to enable them to punch and kick the other opponents

C. to take part in tournament and win prize.

D. to get rid of their mental diseases and run motorcar

Wednesday is the time ________ according to the text.

A. when the students with mental disease will begin to learn Tae Kwon Do 

B. when Hansen’s students will give a display of what they have learned.

C. when Hansen’s students will replace their black belts with white belts.

D. when the parents can see how Hansen teach their children with mental disease.

The example of Christina in the passage suggests________.

A. children are learning Tae Kwon Do with their parents’ company.

B. Rob Hansen is a strict coach of teaching Tae Kwon Do 

C. children with mental disease are interested in Tae Kwon Do

D. Tae Kwon Do can cure mental disease.

What can we infer from the passage?

A. Learning Tae Kwon Do is beneficial to children with mental disease both in health and mind.

B. Any child with mental disease should come to learn Tae Kwon Do.

C. Parents understand why Rob Hansen teach children with metal disease.

D. More schools like The Maum Sin Yong School are needed in America.

Shundagarh is a village on India's east-facing coast.It is a village of simple mud and grass houses built on the beach just above the waterline.The Khadra Hills rise immediately behind the village,to a height of one hundred and fifty meters.A simple,good-hearted old man,whose name was Jalpur,farmed two small fields on the very edge of these hills.From his fields he could see the fishing boats that travelled up and down the coast.He could see the children playing on the sands;their mothers washing clothes on the flat stones where the Shiva River flowed into the sea;and their fathers landing the latest catch or repairing nets and telling stories that had no end.

All Jalpur owned in the world were the clothes he wore day in and day out,the miserable hut(小屋) that he slept in at night,a few tools and cooking pots—and his fields.The corn that he grew was all that made life possible.If the weather was kind and the harvest was good,Jalpur could live happily enough—not well,but happily.When the sun was fierce,and there was little or no rain,then he came close to the line between life and death.

Last year the weather had been so kind,and the harvest promised to be so good,that Jalpur had been wondering whether he could sell all that he had and live with his son farther up the coast.He had been thinking about doing this for some years.It was his dearest wish to spend his last days with his son and his wife.But he would go only if he could give;he would not go if it meant taking food out of the mouths of his grandchildren.He would rather die hungry than do this.

On the day when Jalpur decided that he would harvest his corn,sell it,and move up the coast,he looked out to sea and saw a huge wave,several kilometers out,advancing on the coast and on the village of Shundagarh.Within ten minutes everyone in Shundagarh would be drowned.Jalpur would have shouted,but the people were too far away to hear.He would have run down the hill,but he was too old to run.He was prepared to do anything to save the people of Shundagarh,so he did the only thing that he could do: he set fire to his corn.In a matter of seconds the flames were rising high and smoke was rising higher.Within a minute the people of Shundagarh were racing up the hill to see what had happened.There,in the middle of his blackened cornfield,they found Jalpur;and there they buried him.

On his grave,they wrote the words: Here lies Jalpur,a man who gave,living: a man who died,giving.
