Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. The noise that affect 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（分貝）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 proposed setting a noise limit of one hundred and twenty decibels in oceans. They have observed that noises at that level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud 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.
Many researchers whose work depends on ocean sounds object to 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 suspect 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 man-made noises.
B. The noises made by themselves.
C. The sound of earthquakes.
D. The sound of the ice-breaking.
2.As to the influence of noises on whales, which of the following statements is true?
A. They are deaf to noises.
B. Noises at a certain level may hurt them.
C. They are easily confused by noises.
D. Noises will limit their ability to reproduce.
3. We can know from the passage that many scientists think that the noise limit of one hundred twenty decibels would______.
A. prevent them from doing their research work
B. benefit them a lot in their research work
C. do good to their health
D. increase the industrial output
4.According to the passage, what will scientists most probably do in the future?
A. They will try their best to decrease noise.
B. They will work hard to cut down noise pollution.
C. They will study the effect of different noises.
D. They will protect animals from harmful noises.
A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what’s happening in their brains.
When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons(神經(jīng)元) are responsible for this processing.
The fMRI (functional Magnetic Resonance Imaging功能性磁共振造影) brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.
Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize which parts of the brain receive more oxygen- rich blood--and therefore, which parts are working to process information.
An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.
The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.
In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly, related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.
51. What is responsible for processing the information sent by your eyes?
A A small region of the brain.
B The central part of the brain.
C Neurons in the brain.
D Oxygen-rich blood.
52. Which of the following statements is NOT meant by the writer?
A Cells in your brain are called neurons.
B The more oxygen a neuron consumes, the more blood it needs.
C fMRI helps scientists to discover which parts of the brain process information.
D fMRI helps scientists to discover how the brain develops intelligently.
53. "Highlighting the areas of the brain at work" means
A "marking the parts of the brain that are processing information"
B "giving light to the parts of the brain that are processing information"
C "putting the parts of the brain to work"
D "stopping the parts of the brain from working"
54. What did the researchers experiment on?
A Animals, objects, and fruits.
B Two volunteers.
C fMRI machines.
D Thousands of pictures.
55.What is the best title for the passage?
A Mind-reading Machine

“Sesame Street” has been called “the longest street in the world”. That is because the television program by that name can now be seen in so many parts of the world. That program became one of American’s exports soon after it went on the air in New York in 1969.
In the United States more than six million children watch the program regularly. The viewers include more than half the nation’s pre-school children, from every kind of economic, racial, and geographical group.
Although some educators object to certain elements in the program, parents praise it highly. Many teachers also consider it a great help, though some teachers find that problems arise when first graders who have learned from “Sesame Street” are in the same class with children who have not watched the program.
Tests have shown that children from all racial, geographical, and economic backgrounds have benefited from watching it. Those who watch it five times a week learn more than occasional (偶然的) viewers. In the US the program is shown at different hours during the week in order to increase the number of children who can watch it regularly.
The programs all use songs, stories, jokes, and pictures to give children a basic understanding of numbers, letters and human relationships. But there are some differences. For example, the Spanish program, produced in Mexico City, devotes more time to teaching whole words than to teaching separate letters.
Why has “Sesame Street” been so much more successful than other children’s shows? Many reasons have been suggested. People mention the educational theories of its creators, the support by the government and private businesses, and the skillful use of a variety of TV tricks. Perhaps an equally important reason is that mothers watch it along with their children. This is partly because famous adult stars often appear on it. But the best reason for the success of the program may be that it makes every child watching feel able to learn. The child finds himself learning, and he wants to learn more.
49. “Sesame Street” is actually ____.
A. a street in the US B. a program for children
C. a program for teachers D. a program for students
50. Children who often watch the program ____.
A. can have problems in school
B. will find it a great help
C. will take no interest in their studies
D. will be well educated
51. What is special about the program?
A. It offers great fun.
B. It makes children feel able to learn.
C. It is shown at different hours during the week.
D. Children learn and enjoy themselves while watching.
52. Why is “Sesame Street” so popular in the world?
A. Because it is supported by the government and businesses.
B. Because it uses a variety of skillful tricks.
C. Because mothers watch it along with their children.
D. Because it makes every child watching it feel able to learn.

以下是有關(guān)吸煙問題的觀點：
| A． Smoking is sure to cause diseases. Just have a look at those people with diseases in hospital and count how many of them do not smoke; you may be surprised at the number. Even these few people might be passive smokers without realizing it. |
| B．We have to admit that the tobacco industry contributes a lot to many countries' economies. It also creates job opportunities. But it's harmful to people in the long run. It's a short-sighted policy to depend on tobacco for money. |
| C．Non-smokers absorb nicotine and other harmful chemicals just as smokers do. This is an especially bad situation for children — some of them absolutely have no choice but to be passive smokers and to have lungs that are not as healthy as a normal child's. |
| D． Despite all the strict laws against smoking, the statistics have shown that more young people are lighting up. While it was absolutely a taboo (禁忌) for a woman to smoke before, now it's quite common to see young girls smoking. Many even walk around with a lighted cigarette in one hand. |
