听力原文： Hundreds of species of marine life manage to survive even in the darkest depths of the ocean. These tenants of the sea have evolved some extremely ingenious devices for locating their food and enemies.
Where the light is very dim, some of these deepwater species have developed enormous eyes with almost telescopic lenses, very much like those of owls. Others, especially the fish that survive where there is no light at all, are quite blind but have developed long feelers that enable them to identify and collect stray bits of food that come within a considerable radius of them.
Some inhabitants of the sea supply their own light. They have built-in torches that they can switch on and off, depending on whether they are pursuing or being pursued. Some have regular lamps, spots of steady light, which spread a faint glow through the water around them. One deepwater squid (鱿鱼) can spray a luminous fluid that lights up its immediate vicinity, a neat variation on the ink ejected by its cousins nearer the surface to becloud and darken the water. It is supposed that about half of the varieties of fish living in the dark depths of the ocean have some power of illumination.

A．Supply their own light.
B．Locate food and enemies.
C．Compensate for the lack of light.
D．Both B and C.
听力原文： Have you ever seen a movie in which a building was burnt down or a bridge was destroyed？ Have you seen films in which a train crashed or a ship sank into the ocean？ ff so, you may have wondered how these things could happen without harming the people in the film. The man who knows the answer is the special effects man. He has one of the most important jobs in the film industry. He may be ordered to create a flood, or to make a battlefield explode. But he may also be asked to create a special effect. It is much more exciting. Once a film director wanted some fish that were swimming in a big glass bowl to stop swimming suddenly while they were seen to stare at an actor. Then the director wanted, the fish to stop staring and swim away. But fish can't be ordered to do anything. It was quite a problem. The special effects man thought about this for a long time. The result was an ides for controlling the fish with the harmless use of electricity. First he applied electricity to the fish howl causing the fish to be absolutely still. Then he rapidly reduced the amount of electricity allowing the fish to swim away. Thus he got the humorous effect that the director wanted.

A．Historical development of filmmaking.
B．Making a special film about fishing.
C．Special man in film industry.
D．Special effects in filmmaking.
M: No. I haven't. But I don't like fish very much anyway.
W: Don't worry, Although it's made primarily from fish, it actually doesn't have a fishy taste. In fact it can be flavored with tomato, cheese, or chocolate for instance.
M: Do you know how this snack food is made？ How could it not taste fishy？
W: First, the fish is cooked, then water and flour are added to make a paste.
M: It sounds awful．
W: Actually the paste is flavorless. The flavorings are added to give it some taste.
M: Well. it still sounds a little strange. But I suppose this product will at least be low calorie and high protein, like health food.
W: Yes, you could call it that.And it has a long shelf life, so it won't spoil quickly. It is also easy to digest and can be made from types of fish that usually aren't eaten or from high grade fish by-products.
M: Mh... Have you got any sample？ I might be willing to try cheese—flavored variety.
W: No. None of these seems to be available yet. As I understand it,this fish snack food probably won't be in the stores for another couple of years. So you have a while to get used to the whole idea
M: A couple of years？ It may just take me that long, but thanks for telling me about it.
(20)
A．To preserve it longer.
B．To give it a particular taste.
C．To make it smoother.
D．To increase the nutrition.
Eight Tips for Eating Well
A healthy balanced diet contains a variety of typos of food, including lots of fruit, vegetables and starchy (淀粉类) foods such as wholemeal bread and wholegrain cereals; some protein-rich foods such as meat, fish, eggs and lentils; and some dairy foods.
1. Base your meals on starchy foods
Starchy foods such as bread, cereals, rice, pasta and potatoes are a really important part of a healthy diet. Try to choose wholegrain varieties of starchy foods whenever you can.
Starchy foods should make up about a third of the food we eat. They are a good source of energy and the main source of a range of nutrients in our diet. As well as starch, these foods contain fiber, calcium, iron and B vitamins.
Most of us should eat more starchy foods —try to include at least one starchy food with each of your main meals. So you could start the day with a wholegrain breakfast cereal, have a sandwich for lunch, and potatoes, pasta or rice with your evening meal.
Wholegrain foods contain more fiber and other nutrients than white or refined starchy foods. We also digest wholegrain foods more slowly so they can help make us feel full for longer.
2. Eat lots of fruit and vegetable
Most people know we should be eating more fruit and vegetable. But most of us still aren't eating enough.
Try to eat at least 5 portions of a variety of fruit and vegetable every day. It might be easier than you think. Try adding up your portions during the meals throughout the day. You can choose from fresh, frozen, tinned, dried or juiced, but remember potatoes count as a starchy food, not as portions of fruit and vegetable.
3. Eat more fish
Most of us should be eating more fish —including a portion of oily fish each week. It's an excellent source of protein and contains many vitamins and minerals.
Aim for at least two portions of fish a week, including a portion of oily fish. You can choose from fresh, frozen or canned —but remember that canned and smoked fish can be high in salt.
What are oily fish？
Some fish are called oily fish because they are rich in certain types of fats, called omega 3 fatty acids, which can help keep our hearts healthy.
How much oily fish？
Although most of us should be eating more oily fish, women who might have a baby one day should have a maximum of 2 portions of oily fish a week (a portion is about 140g). And 4 is the recommended maximum number of portions for other adults.
Anyone who regularly eats a lot of fish should try and choose as wide a variety as possible.
4. Cut down on saturated (饱和的) fat and sugar
Fats
To stay healthy we need some fat in our diets. What is important is the kind of fat we are eating. There are two main types of fat:
- saturated fat —having too much can increase the amount of cholesterol (胆固醇) in the blood, which increases the chance of developing heart disease
- unsaturated fat—having unsaturated fat instead of saturated fat lowers blood cholesterol
Try to cut down on food that is high in saturated fat and have foods that are rich in unsaturated fat instead, such as vegetable oils, oily fish, avocados, nuts and seeds.
Foods high in saturated fat are: meat pies, sausages, meat with visible white fat, hard cheese, butter and lard, pastry, cakes and biscuits, cream, soured cream and creme fraiche, coconut oil, coconut cream or palm oil.
For a healthy choice, use just a small amount of vegetable oil or a reduced-fat spread instead of butter, lard or ghee. And when you are having meat, try to choose lean cuts and cut off any visible fat.
Sugar
Most people are eating too much sugar. We should all be
A．Y
B．N
C．NG
A．It"s healthy food.
B．Its flavor is special.
C．It goes well with fish.
D．A high grade of fish is used in its preparation.
听力原文： Why do people want to save the Whales？ There are two important reasons. One reason is that whales help to keep a balance between plants and animals. People have disturbed this balance. People get rid of their wastes by throwing them into the oceans and seas. People's sewage and garbage increase the salt in ocean and sea water. The increased salt helps some plants and some very small animals to grow. These plants and animals can be harmful to fish. Whales eat enormous amount of plants and animals that grow in very salty water. Therefore, whales are very important because they keep the ocean environment clean enough for fish. In addition, because fish provide necessary food for many people, people need whales, and many people want to save them.
(23)
A．Because whales keep a balance between plants and animals on land.
B．Because whales eat a lot of fish.
C．Because whales eat large amounts of garbage.
D．Because whales keep oceans clean for fish, and people need fish.
听力原文： In different parts of Britain, people call their meals by different names. It's very complicated. For most people the main meal of the day is called dinner. But some families eat this at mid-day, others eat it in the evening. People who have dinner in the evening have a smaller meal called lunch at mid-day, and people who have dinner at mid-day usually have another meal which they call tea between five and six, or they have supper a little later.
For most people, breakfast is a bowl of cereal followed by toast and jam with a cup of coffee or tea. Lunch is usually a very quick meal; most people have a sandwich or a light snack. Dinner may have two or three courses. First a starter, for example soup, then a main course with meat or fish and finally a dessert.
It is probably tree that British food does not have a very good reputation among people from overseas. In general, though, it has improved considerably in recent years.
(26)
A．Supper.
B．Lunch.
C．Breakfast.
D．Dinner.
They are snakehead fish, the nightmarish (噩梦似的) creatures from Asia that made news when they were discovered living in a Maryland pond in 2002. They were said to be able to breathe air and walk on their fins, devouring (吞食) everything in their path.
Secretary of the Interior Gale A. Norton called them "something from a bad horror movie" before ordering a federal ban. And to guarantee that they could not escape, the whole Maryland pond was poisoned.
Last month, biologists with New York State's Department of Environmental Conservation were doing a routine sampling of the fish in the brackish water at Meadow Lake in Flushing MeadowsCorona Park in Queens when, to their horror, they found a northern snakehead fish, then another and another until they had five, including one monster 28 inches long. "At that point," said James J. Gilmore Jr., a biologist who is regional supervisor of natural resources at the state agency's New York City office, "we knew we had a problem."
To confirm that the fish were snakeheads, Mr. Gilmore sent photographs to the United States Geological Survey office in Gainesville, Fla., which is mission control for the national crusade to eradicate snakeheads. "As soon as I saw the pictures, I said,' Oh no, not again,'" said Walter R. Courtenay Jr., a fisheries biologist with the Geological Survey who has tracked down snakeheads in Massachusetts, Pennsylvania and Virginia. His message to New York: Get rid of them.
The snakehead, a native of Asia, is a compact stalking machine packed with rows of sharp teeth, a torpedo-like body suited to darting out of hiding holes to chase, and catch, other fish and a voracious appetite that can lead them to devour every other fish in the lake or pond where they live. "They are top predators (食肉动物)," Mr. Gilmore said. "They will outcompete other native fish for food and dominate the lake."
The carp, white perch and pumpkinseed fish that now inhabit the 93-acre Meadow Lake will be wiped out if the snakeheads can reproduce unchecked, Mr. Gilmore said. That is why it is critical to act now, before they are well established. He believed someone might have bought several in an Asian fish store a few years ago before the ban was enforced and deliberately released them in the lake, hoping they would reproduce there and provide some inexpensive dinners.

A．a lady in charge of the harbor
B．the symbol of New York City
C．the statue of liberty
D．a famous American woman
