The space shuttle Discovery has had a long and busy career. For 27 years, it has worked for NASA, carrying astronauts to space and back on 39 missions. On March 9, 2011, after returning from its final voyage, the world’s most traveled spaceship was retired.
A crowd of shuttle workers, reporters and schoolchildren waited to greet Discovery at Kennedy Space Center in Cape Canaveral, Florida. Three minutes before noon, they watched as the shuttle appeared in the sky and made one last touchdown. “For the final time: wheels stop,” Discovery’s commander Steven Lindsey said when the shuttle rolled to a stop.
Discovery’s final trip was to the International Space Station (ISS), a giant space lab in the sky. Discovery’s crew took care of the last U.S. construction project at ISS. They delivered 10 tons of supplies for the ISS. The six-person crew also dropped off an unusual companion for ISS’s researchers: a human-like robot named Robonaut 2. Astronauts will assemble(組裝)R2 at the ISS over several months.
Now, NASA is winding down its shuttle programme. NASA is to begin work on new spaceships that can travel longer distances. Discovery’s retirement is the first of three. Endeavor, another shuttle, is scheduled to make its final voyage soon. And Atlantis’s last trip is planned for the end of June.
Museums across the country have requested the retired shuttles. The Smithsonian’s Air and Space Museum, in Washington, D.C., was the lucky recipient(接收者)of Discovery. The museum’s collection contains hundreds of NASA artifacts.
Where will the other shuttles go? You’ll have to wait to find out. NASA will announce its decision on April 12, the 30th anniversary of the first space shuttle launching. Stay tuned!
【小題1】As part of the final mission, Discovery’s crew___________.

A.carried researches to space
B.a(chǎn)ssembled the Robonaut 2 at the ISS
C.brought supplies to the ISS
D.went on a spacewalk
【小題2】The underlined phrase “winding down” in Paragraph 4 probably means _________.

For centuries people dreamed of going into space. This dream began to seem possible when high-flying rockets were built in the early 1900s.

In 1903 a Russian teacher named Konstantin Tsiolkovsky figured out how to use rockets for space travel. His plan was the first one in rocket science to use correct scientific calculation. About 30 years later, a U.S. scientist named Robert Goddard built the first rockets that could reach high altitudes. During World War II, German scientists built large rockets that could travel very far and carry dangerous explosives. After the war, scientists from Germany went to the United States and the Soviet Union to help those countries build space rockets.

These two countries were soon racing to get to space first. Each of these countries wanted to prove that it was stronger and more advanced than the other one. Both countries also had powerful bombs. People in the United States were worried when the Soviets were first to launch a space satellite, which was called Sputnik. The Soviets were also first to send a person into space. Yury Gagarin orbited the earth in the Vostok I spaceship in 1961.

The US government set a goal for its space program to be the first country to put a person on the Moon. The U.S. space program built a series of Apollo spaceship. These vehicles were powered by huge Saturn 5 rockets. In 1969 Apollo II took three men to the moon successfully. Nell Armstrong became the first person to walk on the Moon.

The Soviets may have lost the race to fly people to the Moon, but they built the first space station in 1971. The United States also built a space station. The space stations allowed people to live and work in space. Then the Soviet Union and the United States cooperated to hook two spaceships together in space. This action ended the "space race". Today a much larger space station, built by several countries together, orbits Earth.

Another new way to go to space is by space shuttle. A space shuttle, first made in the United States in 1981, looks like an airplane. Astronauts who fly spaceships have used shuttles to help put satellites into space.

1685 was a very good year for German composers. Within the space of a month, two of the greatest were born: Johann Sebastian Bach and George Frideric Handel.
Handel’s father was a barber and surgeon, which sounds like a strange combination today, but back then those occupations went hand in hand. Even though Handel was very interested in music, his father didn’t think that was a good way to earn a living, so he wanted his son to be a lawyer. The story goes that Handel smuggled a quiet piano into the house so that he could practice in secret.
One day, Handel went along when his father went to shave a duke. While his father was working, Handel sat down and played the duke’s organ. The duke was so impressed that he convinced Handel’s father to let his son study music, and Handel finally got to learn how to compose.
Handel soon discovered that what he liked most was opera. In fact, he was so passionate about opera that he even fought a duel (決斗) over it with one of his friends. Since Italy was the place to learn about opera composing, Handel went off to Italy to study. When he got home, he got a job as court composer for a German prince.
Having landed such a wonderful job, Handel immediately asked his boss for time off. He wanted to go to England, where he’d heard that there weren’t nearly enough composers to satisfy the British taste for Italian opera.
After great success writing opera in London, Handel came back to Germany. Then fate played a funny trick on Handel and his boss. The Queen of England died, and it just so happened that the prince Handel worked for was next in line to the British throne. When he arrived in London as King George, followed Handel, his court composer in Germany.
In addition to serving the King, Handel became one of the most successful opera composers of his time. And he also produced them and traveled all over Europe to hire the best singers. There are stories of battles with rival opera producers and of fights between rival singers. Handel apparently had quite a temper.
If you ever go to London, look for Handel’s grave in Westminster Abbey, where there’s a wonderful monument to him.
【小題1】How did Handel begin to learn to compose?

A.His father was sure of his future success.
B.His performance impressed a duke.
C.He begged his father to send him to Italy.
D.He practiced hard and taught himself music.
【小題2】What does the underlined word “smuggled” mean in the passage?
A.bought secretlyB.took secretly
C.carried in advanceD.possessed personally
【小題3】 Why did Handel later settle down in Britain instead of Germany?
A.Because he could find better jobs in London.
B.Because he enjoyed greater fame in London.
C.Because his boss became King of Britain and brought him along.
D.Because London was a wonderful place to learn about opera.
【小題4】Which of the following words can NOT be used to describe Handel, as shown in the passage?
A.bad-temperedB.talentedC.enthusiasticD.optimistic
【小題5】 Which of the following statements is WRONG according to the passage?
A.Handel was born in the same year with Bach.
B.Many people worked both as a barber and a surgeon.
C.Handel quit his job to learn about opera in Italy.
D.Handel was buried in London and was built a monument.

If you live in America in the 21st century you'll probably have to listen to a lot of people tell you how busy they are. It's become the default response when you ask anyone how they are doing: “Busy!” “Crazy busy!”. It is, pretty obviously, a boast disguised as a complaint. And the common response is a kind of congratulation:“ That's a good problem to have, ”or“ Better than the opposite.”

    Notice it isn't generally people pulling back-to-back shifts in the ICU or commuting by bus to three minimum-wage jobs who tell you how busy they are. What those people are is not busy but tired. Exhausted! Dead on their feet. It's almost always people whose busyness is purely self-imposed work and obligations they've taken on voluntarily, classes and activities they've “encouraged” their kids to participate in. They're busy because of their own ambition or drive or anxiety, because they're addicted to busyness and dread that they might have to face in its absence.

    Almost everyone I know is busy. They feel anxious and guilty when they aren't either working or doing something to promote their work. It's something they have chosen. Busyness serves as a kind of existential reassurance(令人安心的保證),a measure against emptiness, obviously your life cannot possibly be silly or tiny or meaningless if you are so busy, completely booked, in demand every hour of the day.

Idleness is not just a vacation. It is as necessary to the brain as vitamin D is to the body, and deprived of it we suffer a mental affliction as ugly as rickets. The space and quiet that idleness provides is a necessary condition for standing back from life and seeing it whole, for making unexpected connections and waiting for the wild summer lightning strikes of inspiration.” Idle dreaming is often the essence of what we do”, wrote Thomas Pynchon. Archimedes' “Eureka” in the bath, Newton's apple :history is full of stories of inspirations that come in idle moments.

1.When many Americans say “Crazy busy”, they mean______.

A. they are really tired of their present situation

B. they are really proud of their present life

C. they are complaining about their current work

D. their life are full of all kinds of problems

2.The writer mentions Archimedes'“Eureka” and Newton's apple to show that________.

A. history is full of interesting stories

B. Archimedes and Newton were very busy, so they made great discoveries

C. people may get inspiration when they are idle

D. inspirations come from hard work

3.The word “its” in the second paragraph refers to_________________.

 ambition       B. anxiety                 C. busyness                      D. dread

4.From the article, we can infer that ___________________.

A. generally people pulling back-to-back shifts in the ICU tell you they are busy

B. “Dead on their feet” means “being tired out”

C. all the kids are self-imposed due to the drive and motivation

D. The author seems to agree that idleness is better than busyness

Brenda Bongos was a happy, artistic girl. She had one big ambition—to play the drums in a band. But one big problem lay in her way. To be good enough to play in a band, Brenda had to practice a lot, but she lived next-door to a lot of old people. Many of them are sick. She knew that the sound of beating drums would really get on their nerves. So, she had tried playing in the strangest places: a basement, a kitchen, and even in a shower. But there was always someone it would annoy.

    One day, while watching a science documentary on TV, she heard that sound cannot travel in space, because there's no air. At that moment, Brenda Bongos decided to become a sort of musical astronaut.

    With the help of a lot of time, books and work, Brenda built a space bubble. This was a big glass ball connected to a machine which sucked out all the air inside. All that would be left inside was a drum kit(成套設(shè)備) and a chair. Brenda got into the space suit she had made, entered the bubble, turned on the machine, and played those drums like a wild child.

    It wasn't long before Brenda Bongos came very famous. Many people came to see her play in her space bubble. Shortly afterwards she came out of the bubble and started giving concerts. Her fame spread so much that the government suggested that she be part of a unique space journey. Finally, Brenda was a real musical astronaut, and had gone far beyond her first ambition of playing drums in a band.

    Years later, when asked how she had achieved all this, she thought for a moment, and said: ''If those old people next – door hadn't mattered so much to me, I wouldn't have found a solution, and none of this would have ever happened.''

The USA is a land of immigrants. Between 1815 and 1914, the world witnessed the greatest peaceful migration in its history: 35 million people, mostly Europeans, left their homelands to start new lives in America. Why did these people risk everything by leaving their homes and families?

First, what forced emigrants to make the decision to leave? One major cause for European farmers to leave was the rise in population which in turn led to land hunger. Another was politics. There was an increased taxation(稅收) and the growth of armies, and many young men fled eastern Europe to avoid being forced to join the army.

Physical hunger provided another pressing reason. Following the collapse (衰退)of the economy of southern Italy in the 1860s, hundreds of thousands decided to start a new life in America. Religion also encouraged millions to leave the Old World.

In short, people chose to leave their homes for social, economic and religious reasons. As a result, by 1890 among a total population of 63 million, there were more than nine million foreign-born Americans.

But what were the attractions? First of all, there was the promise of land which was so scarce in Europe. Next, factories were calling for workers, and pay conditions were much better than back home. Men were needed to open up the West and build the long railroads, and new towns needed settlers to live in and to develop business. There was the space for religious people to practice their faith in peace.

This immigration meant that by around the 1850s Americans of non-English had started to be more than those of English. As we know, there were losers. To start with, there were those unwilling immigrants, the slaves who had been used as a source of cheap labour. Nor should we forget the equally unlucky American Indians. By 1860 there were 27 million free whites, four million slaves and a mere 488,000 free blacks.

Nowadays, the USA is still seen by millions as the Promised Land. As always, it remains an attractive place to those who think it will offer them a second chance.

1.What is not the cause for people to leave their homeland?

A. The search for religious freedom.

B. The search for adventure.

C. Unwillingness to join the army.

D. Economics.

2.Why was life of the 19th Century European farmers difficult?

A. There was no land.

B. There was no peace.

C. The population had gone down.

D. There were too many of them.

3. Which of the following was not an attraction of the USA?

A. Employment                                                               B. A healthy life

C. freedom of religion                                          D. Business opportunities

4.What is the topic of this passage?

A. The USA is still seen by millions as the Promised Land.

B. The USA is a land of immigrants.

C. Religion encouraged millions to leave the Old World.

D. About one-eighth of non-native born Americans live in the USA in 1890.

5. The American Indians __________.

A. were as fortunate as the slaves    

B. were more unfortunate than the slaves

C. were the most unfortunate  

D. were as unfortunate as the slaves
