In earliest times, men considered lightning to be one of the great mysteries of nature. Some ancient people believed that lightning and thunder were the weapons of the gods.
In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning 1.6 kilometres long has enough electricity to light one million light bulbs .
The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year he also built the first lightning rod (避雷針). This device protects buildings from being damaged by lightning.
Modern science has discovered that one stroke of lightning has a voltage (電壓) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers, and travel at a speed of 30 million meters per second.
Scientists judge that there are about 2,000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average of one person every day.
The safest place to be in case of an electrical storm is in a closed car. Outside, one should go to low ground and not get under tress. Also on,e should stay out of water and away from metal fences. Inside a house, people should avoid open doorways and windows and not touch wires or metal things.
With lightning, it is better to be safe than sorry.

A．the godsB．the earth
C．the skyD．nature

A．In the U.S about one person per day dies from lightning.
B．Swimming during a thunder storm is a good idea.
C．The Empire State Building frequently gets hit by lightning.
D．A closed car is the best place to be during an electrical storm.

A woman came out of her house and saw three old men sitting in her front yard. She said, "I don't think I know you, but you must be 36. Please come in and have something to eat."
"Is the man of the house home?” they asked. "No", she replied, "He's out." "Then we cannot come in", they replied.
In the evening when her 37 came home, she told him what had happened. "Go tell them I am home and invite them in!" The woman went out and invited the men in. "We do not go into a 38 together," they replied. "Why is that?" she asked.

Imagine landing in a foreign country where you cannot speak the language, understand the culture and don’t know anybody. Wouldn’t it be nice to have a friend who could help you out?
John Smith, an English explorer who landed in America in 1607, found the best friend ever. She was a Native American named Pocahontas (1595-1617). And she did more than teach Smith the language: she saved his life, twice.
Smith was captured(捕捉) by members of Pocahontas’s tribe(部落) and was going to be killed. But for some reason, the Chief’s daughter, Pocahontas, felt sorry for Smith (who was probably the first white man she had ever seen) and threw her body over his to protect him. Smith returned safely to the small village he was living in. During the winter the English settlers did not know how to get food from nature. Pocahontas often brought food for Smith and his friends.
A year later Pocahontas’s father tried to kill Smith again because the Native Americans were very scared the English would try to take over their land. Pocahontas warned him and he was able to escape. Later she became a Christian and eventually married an Englishman named John Rolfe. She spent the last year of her life in London. Pocahontas has become an American legend. Her life story has been re-created in many books and films, including Disney’s 1995 film, Pocahontas.
One of the reasons she is so popular is that many Europeans look at Pocahontas as an excellent example of how a minority can adjust into the majority. Pocahontas is also respected because of her selfless love. She proved that people can be kind and loving even to people of a different race or culture. John Smith was very different from Pocahontas but she could see he was a good man and that was all that mattered. No race or country owns goodness, love and loyalty.
小題1: What difficulties might early European settlers meet in America EXCEPT ___________?
A．the fierce conflict with Native Americans
B．lack of food in winter
C．bad-tempered natives who enjoyed killing
D．unfamiliarity with a foreign land
小題2: Pocahontas saved John Smith twice because ___________.
A．she believed in general kindness even to people of a different race
B．she wanted to become a Christian and marry an English
C．he was the first white man she had ever seen in her life
D．she was on the settlers’ side and against her cruel father
小題3:Which is Not an element to make Pocahontas a legend?
A．Her tribal background and her marriage to a white settler.
B．The recreation of her life story in the 1995 Disney film.
C．Her complicated life story different from common people’s
D．Her selfless help to people regarded as enemy of her tribe.
小題4:What can we infer from the passage?
A．People from different cultures can never really get along well with each other.
B．The Europeans think the early settlers should have learned to adjust to the local cultures.
C．The creation of America is based on the settlers’ victory over the Native Americans.
D．The battles between early settlers and Native Americans resulted from their fighting for land.

                                       D
You may picture firefighters holding a hose (水管) outside of a burning building, but the Golden Eagles Hotshots don’t fight fires quite that way. When they go into action, you may not even see a fire truck.
The Hotshots are firefighters who battle fires in wildness areas. But don’t think you’ll only find them in their home state California. Wherever there is a national wildfire emergency, the Golden Eagles Hotshots could be there.
But these firefighters don’t work the same way as firefighters in a big city. They work in areas where there are a large number of trees, bushes, and grass. They climb up and down steep hills to clear brush and burnable debris（殘�。�. They sometimes use water, but they often fight fire with fire!
They do that by lighting what are called “backfires,” which are small, controlled fires that burn up fuel in the path of large wildfires. That way, when the wildfire gets there, it has nothing to burn and nowhere to go, because all the burnable fuel has already gone up in smoke.
The Hotshots also clear away fuel using old-fashioned hard work. For example, they use a saw to cut away trees and heavy brush that could catch fire.
Of course there are times when the Golden Eagles Hotshots do have trucks to supply water to the fires. But the water is limited, and these guys have to rely on hard work more than anything. Physical fitness is very important. They have to be in great physical shape to handle steep hills and difficult terrain(地形) while carrying a 60-pound pack.
The Golden Eagles Hotshots definitely work hard for their pay. But thanks to their efforts, many lives have been saved, many houses have not burned, and countless trees are still standing.
小題1:67. The firefighters mentioned in the passenger. 
A．do much of their work in California
B．a(chǎn)void climbing steep hills in their work
C．do their work equipped with advanced tools.
D．carry out their work mostly in forests and mountains.
小題2:68. According to the passage, why do the firefighters light “backfires”?
A．To signal for help.B．To remove obstacles.
C．To protect trees and bushes.D．To prevent the fire from spreading.
小題3:69. What can we learn about the Golden Eagles Hotshots?
A．They are firefighters working in big cities.
B．Their work requires physical strength.
C．They are voluntary firefighters working for free.
D．They usually hold a hose to put out the fires.
小題4:70. What is the author’s attitude towards the Golden Eagles Hotshots?
A．AppreciativeB．DoubtfulC．WorriedD．Critical

China in the 21st century is making great progress in space technology. In 2003, the country sent up the manned spacecraft Shenzhou-V. Four years later, Chang’e-I went into orbit (軌道) around the moon. In 2008 a Chinese man did the country’s first spacewalk.
These achievements would have been unthinkable without the contribution of Qian Xuesen, a key scientist on space programs and rocketry (火箭技術(shù)) of the People’s Republic of China. This pioneering scientist passed away in Beijing on October 31 in 2009 at the age of 98.
Once called “the father of our space industry”, Qian began working on China’s missile and space technology in 1956, when China had little technology. When asked by General Chen Geng whether the Chinese could develop their own missiles, Qian said Chinese could do anything that foreigners could.
His research helped lead to the explosion of China’s first atomic bomb (原子彈) in1964, as well as to its first man-made satellite in 1970 and its first manned spacecraft in 2003.
Qian was born in Shanghai. He graduated from Shanghai Jiaotong University in 1934.Then he studied in the US at the Massachusetts Institute of Technology and later at the California Institute of Technology. During World WarⅡ, Qian’s research contributed to the development of rocket technology that the US military (軍隊) began using in the 1940s. He was once prevented from leaving the country because it was decided that he knew too much about certain military matters. It was not until in 1955 that Qian returned to China with the help of the late premier Zhou Enlai.
“I plan to do my best to help the Chinese build a nation where they can live with dignity (尊嚴) and happiness, ” Qian told reporters before sailing for China in 1955. The great scientist devoted all his life to keeping the promise.
小題1: What is the article mainly about?
A．It gives a short history of Chinese missile and space programs.
B．It is about how Qian contributed to the Chinese space program.
C．It lists important events that Qian experienced.
D．It is a brief introduction to Qian, a famous Chinese scientist.
小題2:. Which statement about Qian is TRUE?
A．He was born in China and brought up in America.
B．He went to America for further study after graduation from university.
C．He returned to his hometown right after finishing his education.
D．He had worked on missiles in the US military before coming back to China.
小題3:Qian was personally involved in many historic events in China EXCEPT       .
A．the first spacewalkB．the first man-made satellite
C．the development of missilesD．the explosion of an atomic bomb
小題4: From the article, we can conclude that       .
A．the US military had hoped to take full advantage of Qian’s talent
B．Qian had an important position in the US military in the 1940s
C．when World War broke out, Qian was studying at Shanghai Jiaotong University
D．it was not easy to get Qian back from the US

Once a circle lost a piece of its own. The circle wanted to be whole, so it went around looking for its missing piece. But because it was incomplete（不完整的）, it could only roll very slowly. It enjoyed the flowers and the sunshine along the way. It talked with worms. It found lots of different pieces, but none of them fit. So it left them all by the side of the road and kept on looking for the missing piece.
Then one day the circle found a piece that fit perfectly. It put the missing piece into itself. It could be whole, with nothing missing. It was so happy and began to roll. Now that it was a perfect circle, it could roll very fast, too fast to see flowers or talk to worms. It realized how different the world was when it rolled so quickly. It felt so sad that it stopped, left its found piece by the side of the road and rolled away slowly.
Sometimes we are perfect when we lost something. A man who has everything is a poor man in some ways. He will never have hopes, dreams or something better. He will never know someone is loving him or someone is giving him something he has always wanted or never had.
We couldn’t be perfect, but we must be brave enough to love, strong enough to forgive, kind enough to share happiness with others and clever enough to know there is enough love around us and then we can always live a wonderful time in our lives.
小題1:The circle rolled very slowly because it __________.
A．spent much time talking to worms

D．lost a piece of its own
