Research on the human brain has been attracting the attention of more and more scientists in recent years, just like the booming hi-tech industry. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i．e．, to transplant a chip into human brain．This idea may make everyone's dream come true．If we compare a human brain to a hard disc, what the scientists are doing is to enlarge the capacity of the hard disc．For the time being, there are some difficulties in such transplant experiments, but scientists never give up．
Experiments were started on animals．In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U．S．turned a bear into a dolphin．
The dolphin was named Ted, and the bear was named Tallin．Using the most advanced technology, deep and detailed studies were made of the swimming action memory area in Ted's brain by the scientists．They got a lot of useful information．The information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin's brain．The information saved on the chip was released by means of electric power．
Recently, another memory transplant was performed at the Motor Nerve Research Institute of the University of California．The comprehensive memory transplanted in the experiment included actions, moods, logic, words, images, etc. The experiment involved an entire transplant of the memory area. This was the largest such experiment done so far.
The transplant was performed from a dog named “Genius” to a dog named “Idiot”．“Genius” could understand and follow up to 100 gestures and orders made by its master．It was a real genius．“Idiot” was the younger brother of “Genius”．It had no contact with people at all since its birth．It became an animal with nothing in its brain, without any memory．
The operation was a complete success．When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” possessed; it was good at memorizing and sensible. It could follow every gesture and any command given by its master．But “Genius” gave no response to its master, and in fact did not recognize him at all．
47．The purpose of the experiment is____.
A．to combine the computer and the human brain
B．to make bear swim
C．to make some stupid dog turn clever
D．to enlarge the capacity of human brain
48．Which of the following statements is TRUE?
A．The scientists transferred a button-sized chip which useful information in Tallin’s brain.
B．The first comprehensive memory transplant was performed at the Motor Nerve Research University.
C．The second experiment wasn’t an entire transplant of the memory area.
D．The Idiot was an animal with memory before brain experiment
49．What does the underlined word “success” refer to?
A．The two dogs woke up.
B．They were both good at memorizing.
C．The Idiot grasped all the abilities of Genius.
D．The Genius grasped all the abilities of Idiot.
50．According to the text, we can infer .
A．a person can know more after the experiment.
B．a bear can swim after being transferred a chip with related useful information
C．a dog can become clever after entire transplant of the memory area
D．it is really good for animals to have been involved in the transplant experiment
The black and white bird came ashore on a beach in the south of the North Island nearly 4,000 miles away from its usual habitat. The creature’s astonishing journey was witnessed by a woman walking her dog as the two-foot bird waddled out of the water in front of her. She said, “It was out of this world to see it. It was this glistening white thing standing up on the sand and I thought I was seeing things.” The tale of the lost penguin is similar to the 2006 children’s film Happy Feet, in which a young penguin finds himself far from home during a voyage of discovery.
Conservationists believe it has completed an incredible journey for such a young bird — it is estimated to be around 10 months old. The most likely explanation for its appearance in New Zealand is the hunt for food. Experts said it may also have rested on an ice floe (浮冰) during its travels and was carried north for a great distance before it made a swim for dry land. Colin Miskelly, a curator of New Zealand Museum, said, “They can spend months at a time in the ocean and come ashore only to moult (脱毛,换毛)or rest.” Mr. Miskelly said the brave bird would have to find its way back south soon if it was going to survive. He said, “It is probably hot and thirsty and has been eating wet sand.” “It doesn’t realize that the sand isn’t going to melt inside it because they typically eat snow — their only liquid.”
New Zealand residents have been warned to give the bird a wide berth — it can inflict (予以) painful bites if threatened.Which of the following is True of Paragraph 1?
| A．A young penguin found himself far from home during a voyage of moulting. |
| B．A creature’s astonishing journey was incredible in the north of the North Island. |
| C．A woman witnessed a 2 feet bird waddled in the children’s film while walking her dog. |
| D．A penguin came ashore on a beach thousands of miles away from its habitate. |
Conservationists tend to explain that____________.
| A．the young bird has completed a pleasant journey of 4,000 thousand miles |
| B．the young bird’s appearance in New Zealand is due to its hunt for food and delay of returning |
| C．the young bird comes ashore in New Zealand only to moult or rest during its voyage |
| D．the young bird is certain to be over 10 months old when it appears on a beach |
What do we know about the penguin according to Mr. Miskelly?
| A．The penguin could spend months at a time in the ocean and came ashore only to have young ones. |
| B．The young bird might have slept on an ice floe and could not swim for dry land. |
| C．The young penguin didn’t realize the sand wasn’t going to melt inside it like snow it eats. |
| D．The brave bird would have to find its way back north soon if it was going to survive. |
What does the underlined part mean in the last sentence?
| A．The residents should keep well away from it when they want to watch the young penguin. |
| B．Some people do not realize the danger of the young bird and they are expected to touch it. |
| C．New Zealand residents want to keep the young bird but it wants to leave the shore. |
| D．If the local people threatened the young bird, it would do harm to other birds nearby. . |
“A thousand-mile journey begins with a single step,” as the saying goes. However, 36 it doesn’t tell us is that once the journey is started, it might be hard to stop.
That’s the 37 for Tang Renli, a senior at Nanjing University of Technology, who has backpacked to more than 200 cities in China during four years of college.

You may 43 how Tang could find the time, being a full-time college student. Did he really skip classes to go travel, like the 44 of his exhibition suggests? “I gave myself one to two weeks every month for travel. But I always took care of my class and 45__ first,” Tang said. Tang, who is a city planning major, has never ___46_ a compulsory course at college.
“I spent more time and effort on my study, 47 during the finals’ weeks,” Tang said. Schoolwork was not the only 48 Tang had to face. His travel budget was 49 so Tang had to 50 what he had. He usually took the cheapest form of transport and stayed at youth hostels ___51 less than 50 yuan per night. There were also times when he walked, hitchhiked, and slept in train stations, police offices and vans.
“Sometimes I felt 52 , helpless and even found myself in _53 ,” Tang said. “But now that I look back, these setbacks _54 my journey, and my life.

It was June 15, and in two days I would be turning thirty. I was not sure about entering a new decade of my life and feared that my best years were now behind me.
My daily routine included going to the gym for a workout（ 锻炼） before going to work. Every morning I would see my friend Nicholas at the gym. He was seventy nine years old and in terrific shape. As I greeted Nicholas on that particular day, he noticed I wasn't full of my usual vitality（活力）and asked if there was anything wrong. I told him I was feeling anxious about turning thirty. I wondered how I would look back on（ 回顾）my life once I reached Nicholas's age, so I asked him, “What was the best time of your life？”
Without hesitation, Nicholas replied, “Well, Joe, this is my philosophical（哲理的）answer to your philosophical question：

When I got my first job and had responsibilities and got paid for my efforts, that was the best time of my life.
When I met my wife and fell in love, that was the best time of my life.
The Second World War came, and my wife and I had to flee Austria to save our lives. When we were together and safe on a ship bound for（开往）North America, that was the best time of my life.
When we came to Canada and started a family, that was the best time of my life.
When I was a young father, watching my children grow up, that was the best time of my life.”

After an earthquake or any similar disaster, parents and teachers need to help children overcome the effects of this frightening and sometimes devastating （ 毁灭性的） experience. Psychologists （心理学家）say that if children go through a disturbing event before the age of ten, they are three times as likely to suffer psychological problems as teenagers. After a disaster children may become easily upset, shy, aggressive , or afraid of wind, rain, noises, or darkness. They may have trouble letting go of their parents and resist going to school or daycare. Some children may even feel guilty thinking that they somehow caused the disaster through their bad behavior. Because of such common reactions, parents and others should begin as soon after the event as possible helping these children.
Some suggestions include talking to the children about what happened, letting the children express their own feelings, spending extra time with them doing activities together and reassuring （使放心）them that you love them and won't leave them. For some children expressing themselves through drawing pictures or writing can be useful. Do everything possible to help children get back to a normal routine; however, don't be afraid to "spoil" these children for a while after the disaster. Let them have extra privileges （特权）and more attention than usual. Encourage the children to grieve （悲痛）after a loss. It should be OK for them to cry. Caring families and friends can do much to heal children victims of disasters.This passage is mainly about_______.
| A．how to help traumatized（心理受到创伤的）children to get over |
| B．the bad effects disasters bring to children |
| C．the psychological problems children before ten are likely to suffer |
| D．the importance of caring families |
