Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.
The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have suggested setting a noise limit of one hundred and twenty decibels in the oceans. They have observed that noises at that level can frighten and confuse whales (鲸).
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals.
The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected (被感染的).
Many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists don’t think that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
1.According to the passage, Which of the following is increasingly dangerous to sea creatures?
A. The sound of cars. B. The sound of voices.
C. Man-made noise pollution. D. The sound of steps.
2.According to the passage, natural sounds include all of the following except ________.
A. sounds made by animals themselves
B. ocean drilling
C. underwater earthquakes
D. the breaking of ice fields
3.Which of the following is discussed in the third paragraph?
A. The same noise level produces a different effect on land and in the ocean.
B. Different places may have different types of noises.

The beautiful oceans that cover three-quarters of our planet are home to some of our most valuable natural resources. However, while our knowledge of outer space is quite wide, the same cannot be said about the deep waters, thanks to the fact that any attempts to monitor them have either been too awkward or too expensive. Now, California-based Liquid Robotics has come up with an invention that is both economical and easily used across the waters.
Called Wave Glides, the autonomous robot that resembles a surfboard consists of two interconnected sections - on the surface is a glider(滑翔机)fitted with solar panels, battery and sensors. Right below underwater is a navigation(航行) glider.
The robot travels at a snail’s pace gathering data. This data is quickly sorted by its solar-powered computer chips and then sent ashore for analysis. This robot contains no battery that needs recharging. It is a zero emission (排放)device that uses wave energy to push itself forward.
The company is working towards making the robot even more autonomous than it currently is. As it now stands, while the robot can sense a danger such as a ship or a shark, it does not have the ability to move away. Liquid Robotics wants to change that and program the robot so that it has the ability to move away from danger.
To encourage the general public to get involved with the informative data collected by Wave Glider, the company is planning to launch four of the robots on a yearlong trip across the Pacific. Two will head for Tokyo and two for Sydney. All the data they collect will be posted online and the person who comes up with the most innovative interpretation will be awarded a prize.
1.What can we infer from Paragraph 1?
A.It costs less to explore the sea than outer space. B.Outer space has more resources than the oceans
C.People do not have as much knowledge of oceans as space. D.Three quarters of natural resources come from the oceans.
2.What do we know about Wave Glider?
A.It is eco-friendly. B.It can be used as a surfboard.
C.It’s shaped like a snail. D.It uses solar energy to move.
3.What change is most likely to be expected of Wave Glider?
A.Traveling more quickly. B.Sensing danger autonomously.
C.Analyzing data underwater. D.Keeping itself away from danger.
4.Why will four robots be launched on a yearlong trip?
A.To find more natural resources. B.To collect data around the world.
C.To get people informed of collected data. D.To test their ability to work underwater.
5.What is the author’s purpose in writing the text?
A.To promote an online contest. B.To call on people to explore oceans.
C.To introduce a new invention. D.To share the data collected in oceans.

Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day. They are: (1) green and yellow vegetables of all kinds; (2) citrus(柑橘)fruits and tomatoes; (3) potatoes and other fruit and vegetables; (4) meat of all kinds, fish and eggs; (5) milk and foods made from milk; (6) bread or cereals(谷类食品), and rice is also in this kind of food; (7) butter, or something like butter.
Paragraph 2
People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether foods are eaten raw or cooked, canned or frozen. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is what you eat every day.
Paragraph 3
There are two problems, then, in feeding the large number of people on earth. The first is to find some ways to feed the world’s population so that no one is hungry. The second is to make sure that people everywhere have the right kinds of food to make them grow to be strong and healthy.

The fact that ants are fascinating insects has been known for some time. Now, scientists have discovered a large number of wood ants living in an abandoned underground storehouse in Templewo, Poland, despite having no obvious source of food.
Polish zoologist Wojciech Czechowski and his team began studying the underground colony in 2013. They found the ants built a 60-cm high nest in the soil directly over the storehouse vertical air pipe. As years passed, the metal covering on the pipe eroded, leaving behind a hole that thousands of worker ants accidentally slip into each day as they go about their daily chores. The scientists say that there are no sources of food in the storehouse. This means that the insects live in a state of near starvation.
In July 2015, the researchers disturbed part of the ant nest in search of larvae (幼虫), cocoons(茧), and queens. They found nothing, leading them to suspect that the lack of food and cold temperatures made reproduction impossible and that the group tending the nest is entirely made up of non-reproductive female workers. Their population is refilled every year, by a new rain of unfortunate ants that slide down the hole. The researchers say that when they returned in January 2016, the nest had been repaired. It appears that despite the terrible conditions, the worker ants do not stop constructing their nest.
Wood ants are known for their ability to adapt to bad living conditions. In this case, the millions of worker ants trapped in the storehouse have no choice. But instead of losing hope, they are making the best of the situation—a classic example of “when life gives you lesions make lemonade.”
1.How did the wood ants arrive in the storehouse?
A. They fell down there by accident.
B. The research team brought them there.
C. The storehouse builders left them there.
D. They were attracted by the environment.
2.What does the underlined word “eroded” in Paragraph 2 probably mean?
A. Expanded. B. Rotted.
C. Exploded. D. Melted.
3.What did the researchers find in the nest?
A. Larvae. B. Cocoons.
C. A queen. D. Worker ants.
4.Why did the population of wood ants remain steady?
A. They had enough food.
B. They were able to reproduce.
C. They adapted to the conditions.
D. They had new comers to join them.

Scientists used to explore探测on the surface of the ocean. Now they are exploring below the surface, too. They want to know about ocean water and the plant and animal life deep in the ocean.
In 1934 the scientist William Beebe dived 3 000 feet below the surface in a hollow steel ball. In 1935 August Piccard dived 10330 feet. In 1960 his son Jean dived to a depth of 35 800 feet. All these early dives were deep. But the divers could not stay down for very long. They had to come back up to the surface after a few seconds. Scientists needed to stay down longer to study life below surface. Gradually they succeeded. Cousteau, a Frenchman, was able to keep men down to a depth of 90 feet for a week.
Now scientists are developing even better equipment. With this new equipment,men can stay below the surface for days or even weeks. In 1962 Cousteau set up a research station 35 feet below the surface. Then,in 1964,he set up another station on the ocean floor of the Red Sea. This was the first undersea station to operate without help from the surface.
Many countries are now studying undersea living. The former Soviet Union has an undersea laboratory in the Crimean Sea. The United States has a laboratory 50 feet down on the ocean floor off the Virgin Islands. In 1970 five men lived there for two weeks. Then a team of five women scientists stayed in the laboratory. Next came other teams of men. All were there to explore the ocean depths and to make plans for the use of its resources. Scientists hope to find enough mineral,vegetable,and animal wealth there to provide food for the entire world.
1.In order to______ ,scientists are exploring below the surface of the ocean.
A. know about the ocean water deep in the ocean
B. stay down longer to study life of the plant and animal below the surface
C. know about the plant and animal life deep in the ocean
D. both A and C
2.Who made the deepest dive______
A. William Beebe.
B. August Piccard.
C. Jean Piccard.
D. Cousteau.
3.Which of the following statements is true____
A. The early divers could not stay down for very long.
B. Up to now only five women scientists have stayed in the undersea laboratory.
C. The purpose of setting up the undersea laboratories is to make plans for the use of the resources in the ocean.
D. None of the above is true.

Some people are pessimistic (悲观) when they think about the future. They say that, a hundred years from now, we will have used up most of the earth’s resources. We will have polluted our sea badly, and be unable to eat fish from it. We will have made air so dirty that we will need to wear masks. The world’s pollution will have doubled, and we will have used all the countryside for housing; there will be no farmland left.
Other people believe that man adapts very easily. They have a different idea of the future. However, in their views, will people be living in a hundred years’ time?
One architect believes that man will move off the land. He suggests that the city of the future will be a huge, pyramidshaped building, which will be floating on the surface of the sea. About 5,000 families will be living there, and the building will contain shops and schools as well as homes. By living on the sea, we will give the farmers more land to grow crops.
As for oil, people will no longer need it: we will be heating our homes with power from the sun. And we will not be short of minerals, because there are plenty under our oceans. At the moment, we do not have the technology to get them out. But, in a hundred years’ time, the optimists (乐观者) say, the new sea cities will be using these resources.
What will be in the shops in the year 3000? What will people be wearing? How will people be traveling?
Scientists who make predictions about the future suggest that, by the year 3000, shops will no longer exist. Computers will have replaced them; and people will order goods from home.
People will be wearing very light, thin clothes. By this time, scientists will have invented a fabric that keeps us cool in hot weather and warm in cold weather.
As for travel, the experts say that most people will be using public transport. Electric cars will be traveling through the streets day and night. Anybody will be able to stop one and use it.
An interesting picture! Unfortunately, we will not be there if these predictions come true.
1.Pessimists believe that in the future ________.
A. seas and oceans will be full of houses
B. we’ll have used up most of the resources
C. we will have not enough fish to eat from the seas

2.Scientists have made the predictions EXCEPT ________.
A. electric cars will be going along the streets continuously
B. the resources under the oceans will never be used up
