Zhang Heng was a famous scientist in the history of China. His invention Hou Feng Seismometer was a great success and it helped us understand the world better.

(AD 78-139)

                      It was invented.
Zhang Heng was born in Nanyang in the eastern Han Dynasty. At that time, there were many earthquakes every year. People thought they were from ghosts. Zhang Heng, however, didn’t believe it. He tried to find ways to study earthquakes for many years and in 132 he invented the first seismometer in the world.
It was used.
But at first, people didn’t believe it and all laughed at him. In February, 138, Zhang heng’s seismometer told there was an earthquake in the west of Luoyang. After four days, three earthquakes really happened in Luoyang area. It was believed to be useful from then on. However, it was lost 1700 years ago.
It was reproduced.
Scientists have been trying to reproduce one like that. In 2012, the latest reproduced seismometer was successfully listed in Shanghai museum. It was reported to have been a little helpful during the earthquakes in Tangshan, Yunnan and Sichuan. It is hoped to be improved better soon and be able to predict coming earthquakes one day.

It feels like every time my mother and I start to have a conversation, it turns into an argument. We talk about something as simple as dinner plans and suddenly, my mother will push the conversation into World War III. She’ll talk about my lack of a bright future because I don’t plan to be a doctor. And much to her disappointment, I don’t want to do any job related to science, either. In fact, when I was pushed to say that I planned to major(主修) in English and communications, she nearly had a heart attack.
“Why can’t you be like my co-worker’s son?” she bemoans all the time. Her co-worker’s son received a four-year scholarship and is now earning 70,000 dollars a year as an engineer. I don’t know what to answer except that I simply can’t be like Mr. Perfect as I’ve called the unnamed co-worker’s son. I can’t be like him. I’m the type of person who loves to help out in the community, write until the sun goes down, and most of all, wants to achieve a career because I love it, not because of fame (名聲) or salary(薪水).
I understand why my mother is worried about my future major. I’ve seen my mother struggle to raise me on her small salary and work long hours. She leaves the house around 6:30 a.m. and usually comes home around 5 p.m. or even 6 p.m. However, I want her to know that by becoming a doctor, it doesn’t mean I’ll be successful. I’d rather follow my dreams and create my own future.
小題1:Which of the following topics do the writer and his mother often talk about?
A.The writer’s studies. B.The writer’s future job
C.Dinner plansD.Wars around the world
小題2:We can infer from Paragraph 1 that the writer’s mother ____________.
A.doesn’t want the writer to major in English
B.doesn’t think the writer should be a doctor
C.gets along very well with the writer
D.doesn’t think working in the science field is a good idea
小題3:The underlined word “bemoans” in Paragraph 2 most probably means _____________.
A.a(chǎn)greesB.shoutsC.complainsD.smiles
小題4:Which of following statements is probably TRUE about the writer?
A.He wants to be like his mother’s co-worker’s son.
B.He wants to find a job in his community in the future.
C.He doesn’t think his mother’s co-worker’s son is perfect.

The owner of a missing cat is asking for help. “My baby has been missing for over a month now, and I want him back so badly,” said Mrs. Brown, a 56-year-old woman. Mrs. Brown lives by herself in a trailer park near Clovis. She said that Clyde, her 7-year-old cat, didn’t come home for dinner more than a month ago. The next morning he didn’t appear for breakfast either. After Clyde missed an extra-special lunch, she called the police.
When the policeman asked her to describe Clyde, she told him that Clyde had beautiful green eyes, had all his teeth but was missing half of his left ear, and was seven years old and completely white. She then told the officer that Clyde was about a foot high.
A bell went off. “Is Clyde your child or your pet?” the officer suspiciously asked. “Well, he’s my cat, of course,” Mrs. Brown replied. “Lady, you’re supposed to report missing PERSONS, not missing CATS,” said the sppeadeotoned policeman. “Well, who can I report this to?” she asked. “You can’t. You have to ask around your neighborhood or put up flyers,” replied the officer.
Mrs. Brown figured that a billboard would work a lot better than an 8”x11” piece of paper on a telephone pole. There was an empty billboard at the end of her street just off the interstate(州際公路) highway. The billboard had a phone number on it. She called that number, and they told her they could blow up a picture of Clyde (from Mrs. Brown’s family album) and put it on the billboard for all to see.
“But how can people see it when they whiz(快速移動) by on the interstate?” she asked. “Oh, don’t worry, ma’am, they only whiz by between 2 a.m. and 5:30 a.m. The rest of the day, the interstate is so full of commuters that no one moves.” They told her it would cost only $3,000 a month. So she took most of the money out of her savings account and rented the billboard for a month.
The month has passed, but Clyde has not appeared. Because she has almost no money in savings, Mrs. Brown called the local newspaper to see if anyone could help her rent the billboard for just one more month. She is waiting but, so far, no one has stepped forward.
小題1:How long has the cat been missing?
A.More than a monthB.More than two months
C.More than three monthsD.It’s been back.
小題2:Who did the old lady finally turn to for help?
A.A billboard companyB.The police
C.The phone companyD.The interstate telephone line
小題3:How is the old lady like?
A.StupidB.LovingC.SmartD.Decisive(有決斷力的)
小題4:The underlined word was mistyped(打錯了). But we can still guess it’s most probable meaning:____________.
A.a(chǎn)ngryB.surprisedC.happyD.excited
小題5:What’s the best title for this passage?
A.An advertisementB.A missing cat
C.A pet’s storyD.Life without cat

Look carefully at the back of a California state quarter. A man with a walking stick is pictured there. A bird called a California condor(大禿鷲)is flying overhead. Who is this man, and why is he so important that he is featured(處于顯著地位)on the back of a coin?
The man on this quarter is John Muir. Even as a child, Muir loved watching nature. As a young man, he spent much of his life exploring the beauty of the wilderness. He walked more than a thousand miles across the country, through fields and woods. John Muir liked writing about the places he visited, describing their beauty.
Muir also wrote about problems. In order to create more farmland for sheep and cattle, many trees were being cut down. This made Muir unhappy and worried, because he knew that trees were important to forests and to the animals that lived in them.Muir believed that nature should be conserved(保護)instead of being changed by human beings. He wrote articles in magazines and newspapers to spread the word about conserving forests. Soon, others began to listen.
Muir wrote letters to important people, such as President Theodore Roosevelt. The president admired Muir’s love for nature. When Roosevelt came to visit Muir in California. Muir convinced(說服)the president to go camping with him for three nights under the trees so they could talk about conservation. Later, President Roosevelt set aside 148 million acres of land for national forests and established(建立)five national parks. National parks are large areas of land that are protected from development. This means that people cannot build homes or businesses there. One of these parks is Yosemite National Park, the area that is featured on the back of the California quarter.
Though it has been almost one hundred years since John Muir died, people continue his work today. His work as a conservationist helped us to see the beauty of our natural world. John Muir made us understand the importance of protecting our earth and our resources---then, now, and for the future.
小題1:Why did President Theodore Roosevelt visit John Muir?

Long long ago, a young man found a spring of delicious clean water while he was going through the desert. He brought some back to the oldest man in his village, who had been his teacher before. After a four-day journey he sent the water to the old man who took a deep drink, smiled warmly and thanked his student for the sweet water. The young man returned to his village happily. The next day, the teacher let another student taste the water. He spat it out, saying it was awful. It went bad because it had stayed in the old leather container(皮革容器) for so many days in such hot weather. The student asked his teacher why he pretended(假裝) to like the awful water. The teacher replied, "You only tasted the water. I tasted the gift. The water was simply the container for love and kindness. And nothing could be sweeter than these."
  I think we understand this lesson best when we receive small gifts of love from very young kids. Whether it's a slice of bread or a piece of colored paper, the natural and right response(反應(yīng)) is to show our thanks and happiness because we get love from the gift.
  To show our thanks doesn't always come naturally. Unfortunately, most children and many adults only see the thing itself. They never feel the meaning of the thing. We should tell ourselves and teach our children about showing thanks and happiness to the persons who give the gifts from their hearts because gifts from the heart are really gifts of the heart.
小題1:Where did the young man find the water?
A.In a spring.B.In a river.C.In a lake.D.In a village.
小題2:How long did the water stay in the old leather container?
A.Six days.B.Five days.C.Four days.D.Three days.
小題3:What does the word “replied” mean?
A.smiledB.criedC.a(chǎn)nsweredD.got angry
小題4:According to the passage, what is the right response when we get gifts from others?
A.We eat it up at once.
B.We only see the thing itself.
C.We think about the meaning of the bread.
D.We usually show our thanks and happiness naturally.
小題5:What does the writer want to tell us?
A.We should never receive anything from others.
B.We should show thanks and happiness when we get the gifts from the heart.
C.We should pretend to love the things given by others all the time.
D.We should give gifts from our hearts.
