“Don’t get discouraged, Hallie,” Kathy said, comforting her with a hug. “It sounds as if you have a bit of a mystery to solve. Maybe you should do a little spying on Maya.”

Feeling better, Hallie put on her scuba gear(潜水服)again and waited. Maya, the dolphin, had been swimming playfully, but suddenly she threw herself to the back of the tank where the filter box(过滤箱)was located. She stuck her nose down behind the box and then swam away.

Hallie followed Maya. “What was she doing here?” she wondered. When she looked behind the box, her question was answered. She swam back and saw Maya was in front of Kathy with a comb in her mouth waiting for her treat.

“Maya! Where did you get that?” demanded Kathy, taking the comb and throwing her a fish.

“I know,” declared Hallie, handing Kathy a handful of items, “I followed her to the filter box and these are what I found.”

From the look on Kathy’s face, Hallie knew everything was beginning to come to light.

“Do you remember the other day you said that Maya really liked her treats?” asked Kathy.“Well, I think this was more than a training exercise for Maya. Every time you found something in the tank, that meant one less fish for Maya. She couldn’t bring all the items to me at once, so she found a hiding place for them. That way you came up empty-handed, but Maya would always get her treat.”

“Okay, Maya,” said Hallie facing the dolphin, “you win! The treats are all yours.”

Maya dived down, and then jumped out of the water, turning herself over in midair. Shaking their heads in disbelief, Hallie and Kathy reached for the fish. Maya deserved the treat.

1.What was the “mystery” in the story?

A. The secret of Maya’s finding the items.

B. The secret of Hallie’s winning the game.

C. The reason for Maya’s liking her treats.

D. The reason for Hallie’s spying on Maya.

2.Maya hid the items because she considered Hallie as a ________.

A. spy

B. competitor

C. playmate

D. trainer

3.At the end of the story, Hallie and Kathy thought Maya was ________.

A. energetic

B. genuine

C. loyal

D. smart

The technique can lead to new ways to produce medicines, the researchers from the universities of Istanbul and Hawaii hope.

As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow(发光) in the dark.

Their efforts produced two rabbits out of a litter of eight that went from being a normal, fluffy white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of a collaboration(合作) between scientists from universities in Turkey and Hawaii.

The rabbits glow to show that a genetic manipulation technique can work efficiently, though the specific color is more cosmetic than scientific. "The green is not important at all – it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor Stefan Moisyadi.

To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Those altered embryos(胚胎). Those altered embryos were then inserted back into the mother. Similar experiments have resulted in glowing cockroaches and cats.

Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said. “The final goal is to develop animals that act as barrier reactive to produce beneficial molecules in their milk that

can be cheaply extracted, especially in countries that can’t afford big pharma plants that make drugs, that usually cost $1bn to build, and be able to produce their own protein-based medication in animals," Moisyadi said.

The rabbits are expected to have the same life span as their non-glowing counterparts(副本), but Moisyadi said he understands people can object to this kind of experimentation involving live animals.

"To the people against, I say: think about, what are the benefits and what are the injuries?" Moisyadi said. "And if the benefits outweigh the injuries, let's go with the benefits."

Moisyadi, a native of Turkey who is now with the University of Hawaii, started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.

1.Moisyadi’s attitude towards this kind of experiment is .

A. doubtful.

B. indifferent.

C. supportive.

D. objective.

2.How did glowing effect produce?

A. It was just the result of genetic selection.

B. Put a light into a mother rabbit’s embryos.

C. Injected glowing cats DNA into a mother rabbit’s embryos.

D. Injected Jellyfish DNA into a mother rabbit’s embryos.

3.The final goal of this research is .

A. To make animals cuter.

B. To make nights brighter.

C. To produce all kinds of glowing animals.

D. To produce beneficial molecules in animals’ milk.

4.What can we learn according to the passage?

A. The life span of glowing rabbits is much shorter than that of non-glowing ones.

B. The glowing rabbits were born only at the University pf Hawaii.

C. Scientists have created glowing cockroaches and cats before.

D. Three rabbits out of eight can glow in the experiment.

The following are about modern wonders of the world.

The Suez Canal

More than 3, 000 years ago, a king of Egypt ordered that a river be built to connect the Mediterranean. Sea (地中海) and the Red Sea. This kind of man-made river is called a canal. However, ancient Egyptians did not keep this canal in use. As years passed, the sands of the great deserts of Egypt closed the small canal.

In 1859, Egyptian workers began rebuilding the canal. It was opened and named the Suez Canal on November I7th, 1869. Though closed several times because of war or political problems, the Suez Canal is still the fastest crossing from the Atlantic Ocean to the Indian Ocean today, saving shipping companies a great deal of time and money.

The Channel Tunnel

The great canal connects oceans. The next great wonder connects land. It is called the Channel Tunnel, or “Chunnel”, connecting Britain with France. The tunnel is 50 kilometers long, built about 45 meters below the earth under the English. Channel (海峡).

The work began in 1987 and it took seven years to finish. The cost was more than 13, 000 million dollars. The Chunnel opened In 1994.

Today, the Chunnel is very busy. High-speed trains carry cars, trucks and passengers from Britain to France and back again. The trains are famous for their smooth, quiet ride. The money paid for the trip is slowly paying for the huge cost.

The Three Gorges Darn

The Three Gorges Dam is perhaps the largest construction project on earth. The work began, in 1993.The Three Gorges Dam is built to produce power and control China’s Yangtze River. The completed dam produces large amounts of electric power.

Completed in 2009, the dam creates a huge lake about 632 square kilometers. Some critics say the dam harms the environment and damages historical areas. More than one million people had been resettled before the dam was finished. Chinese government officials say it will lead to increased economic development in cities near the dam, and the terrible floods caused by the Yangtze have become memories of the past.

1.Which of the following took the longest time to build?

A. The Red sea. B. The English Channel.

C. The Chunnel. D. The Three Gorges Dam

2.What do we know about the effects the Three Gorges Dam has on China?

A. It helps to protect the historical sites.

B. It saves time for ships to travel upstream.

C. It reduces the number of flood victims.

D. It powers an area of 632 square kilometers.

Skating backwards on ice is a bit difficult but once you master the basis, there’s nothing like it. Follow the steps given below and you will be able to skate backwards in no time.

1.

The first thing that you need to do is, stand straight. If you feel that you are falling backwards, then just put your chin up and slightly bend your knees. Don’t worry; this happens to all.

2.

The most important step while learning how to skate backwards, is having enough confidence in yourself and in what you are doing. How can you achieve this? By practice, Just practice rolling backwards down a gentle slope every single day or just by pushing off from a wall or something of that sort.

3.

Confident now? Great! Now the next step is to maintain your speed.While rolling in a straight line with one skate, with the other try sculling(滑浆), that is, keep pushing yourself backwards with an outwards stroke(滑动).Now bring the skate which you were using to scull, and then again, repeat the same process.Make sure that you put most of your weight on the skate which is moving straight and not the one with which you are sculling.Now, try the same thing using the other foot.Again keep doing this till you are confident enough.

4.

Once you are confident that you can scull with either foot, the next thing that you have to do is increase your speed.Try some of your own tricks now.Scull with either foot or with both at the same time.

5.

While you keep one foot straight, keep sculling with the other.You can do that simultaneously with both feet.Concentrate on what you are doing but don't get so involved that you don't see where you are going.If you are not watching your back, you might just bang against something or someone.

A. Find Another to Practise with You

B. Increase Your Speed Now

C. Gain Your Courage

D. Stand Straight

E. Maintain Speed

F. Scull and Be Aware

G. Confidence is What You Need
