Participants in an online forum were asked whether space exploration was worthwhile. Here are some of the comments they posted:
Planet Girl 7.17 pm
Our world is damaged by war, hunger and poverty. Billions of people struggle just to survive from day to day. Meanwhile the US space agency has US $16 billion to play with every year. We must deal with the world’s urgent problems. Space exploration is a luxury we cannot afford.
Dragon 7.18 pm
That $16 billion spent on space is nothing compared to the $370 billion spent on the military.
JJ 7.20 pm
Exploring space is investing in the future. Everyone knows we’re running out of resources. There’s massive over-population too. The solar system has heaps of resources we can use for mining, and maybe we can explore other planets. If we don’t do it now, it might be too late.
Planet Girl 7.22 pm
We have to settle problems of over-population and resource consuming here on Earth, instead of chasing science fiction dreams. Otherwise we will just export our unsustainable lifestyle to another planet. We might consume the whole universe!!
JJ 7.23 pm
Space explorers rock! They know what they are in for, and they still do it anyway. That’s what I call courage! We humans have always struggled to expand our horizons. We want to know what else is out there. Who knows, maybe we’ll discover the solution to all our problems out there!
Switched-on 7.25 pm
Space exploration has had a huge effect on our lives. Want to talk to someone halfway around the world? Sure. Get the weather forecast? Coming right up. Check exactly where you are? Absolutely. It’s all possible, thanks to satellite technology, global positioning systems, and the rest. If there was no space exploration, we’d be sitting around in the dark, not talking online!
Penny 7.50 pm
Satellites are launched by private companies — for profit. Planet Earth doesn’t always benefit. Exploring remote planets certainly does not contribute to life on Earth.
The underlined sentence(Par.2) means that space exploration is_________.

正确答案
B
We are admitted into the full-time school called “life”. Every day in this school, we have opportunities to learn new lessons. No matter whether we like these lessons or not, we have to take them, because they are our lessons.
Why are we here in this world? What is the purpose of life? Humans have tried to discover the meaning of life for thousands of years, but failed to get the answer, because the meaning of life is different from person to person.
Each one of us has his or her special purpose and path, unique and different. As we travel on our life path, we will learn many great lessons in order to fulfill that purpose. Learning our lessons well is the key to discovering the real meaning of our own life.
As we travel through our lifetime, we may be taught hard lessons that others don’t have to face, while others spend years struggling with problems we don’t need to deal with. We may never know why we love English, not physics, which indicates that our path is different. While traveling on our own path, sometimes alone, we should, first of all, take a basic lesson in openness.
Openness means being receptive. Life will present us with so many lessons, none of which are useful to us unless we can recognize them and are open to their values. These lessons are not easy to learn, but we should regard them as gifts. But how can we recognize these lessons? It is a matter of what “glasses” we are wearing at the time. It is not difficult to spot them if we take them as opportunities. So when we are not open to learning our lessons, failing a weekly English test might be like a disaster rather than an opportunity to us. Of course, the hard lessons may not be fun, but they can actually be the biggest gifts we receive from life.
The example of “we love English, not physics” is mentioned to show that _______.

The chicken-loving dog spent last month guarding the island’s penguin colony, with great success.
A SOUTH-WEST Victorian chicken farmer known as Swampy and his dog Oddball may have found a way to save some of Australia’s endangered wildlife from enemies. After Warrnambool’s once flourishing penguin population was killed in large numbers by foxes and dogs until only 27 remained, Allan Swampy Marsh hatched an effective plan to save the birds. His four sheepdogs had been protecting his chickens against enemies for a decade. He figured they could do the same for the penguins. “The difficulty was trying to convince all the wildlife wallies to think outside the square,” Mr Marsh said. “It’s not an unselfish view of penguins or chicks but the sense of territory(领地) that makes the dogs work, and it is far stronger in these dogs than any other trained breed.”
Oddball’s work as guardian of Middle Island’s colony last month was a success. At the end of the month, 70 pairs of happy feet were counted returning to the island. About 2,000 penguins occupied the island in the 1990s. “Oddy is really protective of the chicks, so to her the penguins were only chicks in dinner suits,” Mr Marsh said. Highly territorial dogs have been bred in Italy to guard livestock for 2,000 years. They manage to keep off trouble makers such as foxes and dogs. The trial’s success has generated interest from overseas. The use of guard animals such as dogs — and even alpacas, which also stop foxes — is now being considered to save other endangered species such as the eastern barred bandicoot.

Young sunflowers turn and swing every day. New findings add to evidence that the plants are animal-like.
Harmer, a professor in the University of California at Davis’ Department of Plant Biology, carried out a series of experiments on sunflowers in the field, in pots outdoors and in indoor growth chambers.
By staking plants so that they could not move, Harmer showed that he could destroy their ability to track the sun. He also noticed that sunflowers prevented from moving were not as tough and leafy as those that were free to move. When plants were moved indoor with a settled overhead light, they continued to swing back and forth for a few days.
The indoor plants did start tracking the “sun” again when the apparent source of lighting was moved across the room. The plants could reliably track the movement and return at night when the artificial day was close to a 24-hour cycle, but not when it was closer to 30 hours.
When sunflowers track the sun, the east sides of their stems grew more rapidly than the west sides. At night, the west sides grew faster as the stem swung the other way. The team identified a number of genes that were expressed at higher levels on the sunward side of the plant during the day, or on the other side at night. A plant growth-regulating hormone, called auxin, appears to be a key driver.
The “dance” to the sun cycle obviously slows when the sunflower matures and its flowers open up. At that point, the plants stop moving during the day and settle down facing the sun in the east.
“Bees like warm flowers.” Harmer said, adding that the bees are cold-blooded, so landing on a warm flower saves them energy and perhaps feels really good.
“The morning warmth changes the flowers in a way to make them more appealing to insects, perhaps causing them to release more attractive scents earlier in the day.” he said. “We’re currently testing this idea.”

Oddball’s work as guardian of Middle Island’s colony last month was a success. At the end of the month, 70 pairs of happy feet were counted returning to the island. About 2,000 penguins occupied the island in the 1990s. “Oddy is really protective of the chicks, so to her the penguins were only chicks in dinner suits,” Mr Marsh said. Highly territorial dogs have been bred in Italy to guard livestock for 2,000 years. They manage to keep off trouble makers such as foxes and dogs. The trial’s success has generated interest from overseas. The use of guard animals such as dogs — and even alpacas, which also stop foxes — is now being considered to save other endangered species such as the eastern barred bandicoot.
The purpose of the last paragraph is to suggest that________.

Young sunflowers turn and swing every day. New findings add to evidence that the plants are animal-like.
Harmer, a professor in the University of California at Davis’ Department of Plant Biology, carried out a series of experiments on sunflowers in the field, in pots outdoors and in indoor growth chambers.
By staking plants so that they could not move, Harmer showed that he could destroy their ability to track the sun. He also noticed that sunflowers prevented from moving were not as tough and leafy as those that were free to move. When plants were moved indoor with a settled overhead light, they continued to swing back and forth for a few days.
The indoor plants did start tracking the “sun” again when the apparent source of lighting was moved across the room. The plants could reliably track the movement and return at night when the artificial day was close to a 24-hour cycle, but not when it was closer to 30 hours.
When sunflowers track the sun, the east sides of their stems grew more rapidly than the west sides. At night, the west sides grew faster as the stem swung the other way. The team identified a number of genes that were expressed at higher levels on the sunward side of the plant during the day, or on the other side at night. A plant growth-regulating hormone, called auxin, appears to be a key driver.
The “dance” to the sun cycle obviously slows when the sunflower matures and its flowers open up. At that point, the plants stop moving during the day and settle down facing the sun in the east.
“Bees like warm flowers.” Harmer said, adding that the bees are cold-blooded, so landing on a warm flower saves them energy and perhaps feels really good.
“The morning warmth changes the flowers in a way to make them more appealing to insects, perhaps causing them to release more attractive scents earlier in the day.” he said. “We’re currently testing this idea.”
What does the underlined word “staking”(Par 3) probably mean in ?

阅读下面短文，按照要求完成阅读任务。
What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology. With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cell, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometimes between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs (The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones).
It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.
71. What are the present major killers according to the writer? (No more than 10 words)
72. What does the underlined word in the 1st paragraph “revolution” mean? (No more than 5 words)
73. How can human live longer in the future? (No more than 10 words)
74. Why are scientists sure that the life of cells can not go much beyond 120 years?(No more than 20 words)
75. If human can live longer in the future, do you think it is bad or good for the society?(No more than 20 words)
正确答案
71. Heart disease, cancer, and aging.
72. Great change.
73. People can take new medicine to repair human organs. / By taking medicine to repair human organs.
74. Because the basic materials of cells, such as those of brain cells, would not last forever.
75. I think it is bad for the society because the earth can’t support the increasing population.（open）

正确答案
Dear Tina,
I’m very happy to hear that you’re coming to China next week. I hope to see you soon.
Now I will tell you something about Chinese table manners. Usually all members of a family have meals together at meals’ time, sitting around the table. The elder sits on the first-class seat, near the interior of a room facing to the door. Dishes are placed on the table and everybody shares. Chopsticks are used instead of knives and forks. Sometimes the host family use their chopsticks to put food into your bowl or plate. This is a sign of politeness. Don’t leave anything on your plate or in your bowl. At the end of the meal you should say thanks to the host.
I hope you’ll have a wonderful time in our country.(104)
Yours
