The deep sea is one of the most mysterious places on earth. Scientists rarely go there. Those few do discover new species all of the time. Many places of the deepest parts of the ocean, where it's forever dark, can light up. Now, a teen's research has shown new light on how one of these swimming animals behaves in darkness.
The giant flashlight fish lives in the Indian Ocean as well as in tropical parts of the central and western Pacific. It lives at depths of up to 400 meters, (about 1,300 feet). But not always. Sometimes it lives in coral reefs in shallow waters. In those shallow waters, the blackish-blue fish comes out only at night. Reef-dwelling members of this species tend to be smaller than those living in deeper waters. Those biggies can grow to lengths of 35meters (14inches). That may not sound like a giant, but they are the largest of their type of fish.
The giant flashlight fish gets its name from a small glow-in-the-dark patch found in a packet of tissue under each eye, explains Caroline Edmonds. She is a 13- year-old student from Fountain Valley, Calif. There, she attends Talbert Middle School. She said that the eye pockets in these fish contain light-producing bacteria.
These bacteria and their host fish have built a relationship that helps both. The fish use the bacteria as a way to communicate with creatures around them. The bacteria gain nutrients from the fish and a safe place to live. When a fish wants to “ flash” its light, it turns the bacteria-filled pocket toward the outside of its body, Caroline explains. When a fish wants to hide its light, it turns the pocket back toward the inside. According to her data, the fish flash most often when they are being fed. They flash least often late at night, when they are resting.
1.The deep sea is dark and mysterious, but _________
A. a teen's research is going to light it up.
B. in the deepest part, lives a swimming animal.
C. scientists are looking for a new species to light up.
D. a kind of glowing fish has been found there.

D. It always lives at depths of up to 400 meters.
3.From where does the giant flashlight fish produce light?
A. Between its wings.
B. Inside its body.
C. Inside its back.
D. Near its eyes.
4.We can infer from the passage that Caroline Edmonds _________
A. is probably on a research team.
B. has learned about the fish in the library.
C. has always focused on her studies at school.
D. is one of the most famous American scientists.
5.What is implied in the last paragraph?

Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water—whether for drinking, agriculture, industry or the raising of fish—will always have to be met. Given this premise (前提), there are two basic routes we can go; more equal access to water or better engineering solutions.
Look at the engineering solutions first. A lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal changes of the river—the pulse of the water. And the fact is that if you build a dam, you generally spoil the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the near future, governments will have no excuses for their ignorance.
The engineers’ ability to control water flows has created new kinds of unpredictability, too. Dams in Africa have meant fewer fish, less grazing and less floodplain (洪泛区) agriculture, none of which were expected. And there average economic life is assumed to be thirty years. Dams don’t exist forever, but what will replace them is not clear.
The challenge for the future is to find new means of controlling water. Although GM technology(转基因) will allow us to breed better dry-land crops, there is no market for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World?
1.What’s the main idea of this passage?
A.The engineering solutions to water resource and their limitation.
B.The challenge for the future.
C.The basic means of controlling water.
D.The challenge for developing crops.
2.The author suggests that governments will have no excuse for their careless ignorance in the future because _____.
A.The ecological destruction will be known to the public by researchers
B.The ecological destruction will no longer be a problem in the future
C.The future is an information age
D.Governments will face greater challenge in the future
3.Which of the following statements is NOT true for meeting our basic needs for water?
A.Water resource should be used more reasonably.
B.More dams should be built in river basins.
C.More wetlands should be protected from destruction.
D.More dry-land crops could be developed in Africa.
4.The last sentence probably implies that _____.
A.No one will invest in developing locally appropriate crops in Africa
B.Researchers have no interest in developing dry-land crops
C.Research on locally appropriate crops in the Third World may be profitable
D.There is less water resource in the Third World

On Christmas morning, I went to the Cockhedge Mall. People there were all busy buying their last minute requirements. I needed to buy a birthday card for my son-in-law whose birthday is the 29th of December. Picking up a few more things as well as my card I went to join the line for the express checkout which was for people who only had a few items in a basket and not a trolley (小推车) load. This line was next to the Customer Service desk.
Seemingly waiting quite a long time, I was jogged out of my thoughts by a voice behind me making comments on the things I bought.
It was so funny when I realized that she was describing the contents of my basket. The owner of the voice was a very pretty young lady. I said to her that I was going to buy a box of Christmas cookies but the only ones left were not to my liking. The lady told me that just opposite Cockhedge in Superdrug they had lots of cookies. I said, “I’m not going to do it now . I had enough of shops and I’m going home. ”
The assistant from the Customer Service came across at this time saying “If there is anyone in the line with a few items in their basket, none of which needed to be weighed, I will check out what they buy at the desk.” Because I had the things which needed to be weighed, the young lady accepted the offer and walked away waving goodbye.
At last my turn came at the checkout. I was walking away when I met my new friend once again who handed me a beautiful box of Christmas cookies. With a big hug she said “Hope you have a lovely Christmas.” She had been into Superdrug to buy me the cookies while I was still queuing in Cockhedge.
What a generosity to a stranger! I was so surprised you could have knocked me down with a feather. My Good Samaritan would never know what a joyful Christmas day I had with my family. Telling them this story, as we ate around the table, kept everyone spellbound.
1.The underlined word “spellbound” in the last paragraph probably means _______ .
A. interested B. disappointed
C. astonished D. frightened
2.Which of the following could be the best title of the story?
A. A Piece of Lucky Feather
B. A Surprise Christmas Gift
C. The Boring Shopping Experience
D. The Unforgettable Big Hug
3.How does the writer feel about the pretty young lady?
A. Worried. B. Satisfied.
C. Grateful. D. Proud.
4.What can we learn from the story?
A. Nobody is sure what will happen the next moment.
B. A simple action can bring other people happiness.
C. Being patient will decrease the waiting time.

For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.
Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants(污染物)can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.
People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases.
As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building—green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb(吸收)or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.
1.Generally speaking, indoor air pollution may be more harmful than the air outside because .
A.indoor air pollution can often make people seriously ill
B.man-made building materials give off dangerous gases
C.there may be more harmful gases outside the buildings
D.the air indoors is polluted, which is very harmful
2.Some kind of indoor pollution can be found in .
A.every modern house B.every old house
C.all kinds of houses D.all kinds of offices
3.The indoor air pollution is caused by .
A.the limit of the flow of air between inside and outside
B.the building way that the builders want to save energy
C.the building things that are made of man-made materials
D.the man-made building materials and the limit of air-flow
4.The reason why we should use different kinds of plants to clean the air is that
A.plants can let out all kinds of pollutants indoors
B.plants may take in more oxygen (氧气)which people need
C.plants can absorb all kinds of harmful indoor chemicals
D.plants can make our houses prettier and more healthy
