Everyone has done experiments in high school laboratories,but have you ever thought about designing a satellite to explore space?

On Nov.19,a team of students from Thomas Jefferson High School for Science and Technology in the US awed peers and even scientists by successfully launching a satellite.

The first satellite designed and built by high school students was sent up into space along with a record setting.28 other small ones on a rocket were sent from a NASA center in Virginia,CNN reported.It took the students seven years to build.

The students call their tiny satellite TJ3Sat,which is named after their school.It is just 10x10x12 centimeters and weighs only 0.89 kilograms,according to Orbital Sciences,a company which developed the rocket and supported the students’ project.It can be controlled with a smartphone.

Like most satellites,TJ3Sat can send and receive data.The small spacecraft is equipped with a voice synthesizer (合成器),which can switch text to voice and transmit those sounds back to Earth over radio waves,said Orbital officials.In this case,anyone can give it a try via the project’s website (school website) by submitting (提交) a text.The texts that get approved will be sent to the satellite,changed to voice and then broadcast back to Earth via radio waves.

“I can say ‘Go Colonials’on our ground station and when it is on the other side of the world,in India,someone can hear‘Go Colonials’over the radio,”the team explains on the website.

The satellite will stay in space for at least three months.

School principal Evan Glazer told The Washington Post that the project started in 2006 as an activity in the spare time.Later it became a research project for a select group of seniors.

At a time when American students are busy with SATs,the launch of the satellite shows what diligent teenagers can achieve when allowed to pursue their own curiosities,Glazer said.

“It used to be that kids growing up wanted to be an astronaut,” Andrew Petro,program executive (主管) for small spacecraft technology at NASA,said in a statement.“I think we might be seeing kids saying what they want to do is build a spacecraft.The idea here is that they really can do that.”

A.influenced

B.amazed

C.delighted

D.inspired

2.Which of the following statements about TJ3Sat is TRUE according to the article?

B.Besides TJ3Sat,28 other small satellites were built by the students.

C.TJ3Sat can receive text messages that the students send into space,which can be changed to voice messages and broadcast back to Earth.

D.TJ3Sat is expected to stay in orbit for the next year,sending out messages together with information about its position in space.

3.According to the article,the launch of the satellite _______.

A.is evidence of the advance of spacecraft technology

Five years after they disappeared, lost jewels belonging to the wife of a US ambassador to the Netherlands were found.

Dawn Arnall had already received an insurance payout for her loss. However, the misplaced gems had been found and held for safe keeping by a hotel she stayed in. staff were unaware that the jewels were worth $ 9m.

The world is full of forgetful people. A man in the English town of Reading even left a sausage casserole in a bus. The dish ended up in the Lost Property Office until it was recovered by his mother, eager for her dinner.

A walker in the Lake District had his food in his mouth but … what about his teeth? After climbing a hill in 2007, David Packer stopped for a chocolate bar. He took his false teeth out, wrapped them up in a tissue and just forgot about them. It took more than a year for the walker to be reunited with them.

Over the past 78 years passengers on London’s transport network have left behind items including human skulls and gas masks from World War II. Since 1934, staff have handled an average of 200 000 items a year. Recently they have used computers to try to track down their owners.

But if you find something and can’t locate the rightful owner, is it finders keepers? It depends on what’s found and how, says John Spencer, professor of law at the University of Cambridge.

If you pick up a coin, you can keep it unless you saw someone drop it, as you wouldnt be able to find the owner by taking reasonable steps.

If it’s a larger sum, you should report it to the police but if the item has been abandoned, the property is yours. One man’s loss is another man’s gain!

There are many older people in the world and there will be many more. A lime?known fact is that over 60 percent of the older people live in developing countries. According to the World Health Organization,by 2020 there will be 1 billion,with over 700 million living in developing countries.

It is a surprising fact that the population ageing is particularly rapid in developing countries. For example,it took France 115 years for the proportion of older people to double from 7 percent to 14 percent. It is estimated(估计) to take China a mere 27 years to achieve this same increase.

What are the implications(暗指) of these increased numbers of older folk?One of the biggest worries for governments is that the longer people live,the more likelihood there is for diseases and for disability. Attention is being paid to the need to keep people as healthy as possible,including during old age,to lessen the financial burden on the state.

Another significant problem is the need for the younger generations to understand and value the older people in their society. In some African countries,certainly in Asia,older people are respected and regarded as the ones with special knowledge. Yet traditions are fading away daily,which does not ensure the continued high regard of older people. As society changes, attitudes will change.

Much needs to be done to get rid of age discrimination (歧视) in employment. Life?long learning programs need to be provided to enable older people to be active members in a country’s development.

Social security policies need to be established to provide adequate income protection for older people. Both public and private schemes are vital in order to build a suitable safety net.

To achieve equality in such matters will take considerable time and effort. One thing is sure:there is no time to be lost.

1.The proportion(比例)of older people________.

A. is bigger in developed countries than in developing countries

B. is one seventh of the population in developing countries

A.Getting rid of age discrimination in employment.

B.Ensuring adequate income protection for older people.

C.Providing free health care for sick older people.

D.Supplying life?long learning programs to older people.

4.The author concludes in the last paragraph that________.

A.governments have spent lots of time in solving the ageing problem

B.population ageing is a hard problem,but it needs to be solved urgently

Grandpa was a carpenter (木匠). One day he was making some boxes for the clothes his church was sending to an orphanage (孤儿院) in Egypt. On his way home, he reached into his shirt pocket to find his glasses, but they were gone. He drove back to the church, but his search turned out to be fruitless.

Suddenly, he realized what happened. The glasses had slipped out of his pocket and fallen into one of the boxes, which he had nailed shut. His new glasses were heading for Africa!

Grandpa had six children and he had paid twenty dollars for the glasses that morning. “It's not fair,” he told God as he drove home. “I've been very faithful (忠诚的) in giving my time and money to YOUR work.”

Several months later, the director of the orphanage was on holiday in the United States. He wanted to visit all the churches that helped him in Egypt, so he came to speak on Sunday night at my grandfather's small church in Chicago.

“But most of all,” he said, “I must thank you for the glasses you sent last year. You see, I had just broken my glasses. Then your boxes arrived. To my surprise, I found a pair of glasses in it and it fit me very well!”

The people listened, happy for the amazing glasses, but thought that the man must have confused their church with another. There were no glasses on their list of items to be sent overseas. Sitting quietly in the back, with tears in his eyes, Grandpa realized that God had played a big trick on him.

I absolutely love Bark magazine! I love the “smiling” pages and the tips on every issue.

Don't waste your money on this magazine. 60-70 percent of it are advertisements, and the articles offer little useful information. It might be suitable for children, but not adults who are serious about educating themselves about dogs.

Dog World

Dog World has many very interesting and thought-provoking (令人思考的) articles for people involved in dog showing, breeding(饲养), performance events, etc. However,over half of the magazine is devoted to breeder ads, which is boring. Still, as a whole, I recommend(推荐) it for the articles. Good articles, but tons of ads.
