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(鲸鱼).
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.
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. 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 |
Which of the following is true of whales？
| A．They won't be confused by noises. |
| B．They are deaf to noises. |
| C．Their ability to reproduce will be lowered by highlevel noises. |
| D．Their hearing will be damaged by highlevel noises. |
According to the passage, what will scientists most probably do in the future?
| A．They will work hard to reduce ocean noise pollution. |
| B．They will protect sea animals from harmful noises. |
| C．They will try to set a limit of 120 decibels. |
| D．They will study the effect of ocean noise pollution. |
A man and his girlfriend were married. It was a large celebration. All of their friends and family came to see the lovely ceremony. Everyone could tell that the love they had for each other was true.
A few months later, the wife came to the husband with a piece of advice, “I read in a magazine, a while ago, about how we can strengthen our marriage,” she offered. “Each of us will write a list of the things that we find a bit annoying with the other person. Then, we can talk about how we can fix them together and make our lives happier together.”
The husband agreed. So each of them tried to think of the things that annoyed them about the other and wrote down what they came up with. The next morning, at the breakfast table, they decided that they would go over their lists.
“I’ll start,” offered the wife. She took out her list. It had many items on it, enough to fill three pages. In fact, as she started reading the list of the little annoyances, she noticed that tears were starting to appear in her husband’s eyes because he never thought that he had so many shortcomings.
The wife continued to read until she had read all three pages to her husband. “Now, you read your list and then we’ll talk about the things on both of our lists,” she said happily.
Quietly the husband stated, “I don’t have anything on my list. I think that you are perfect. I don’t want you to change anything for me. You are lovely and wonderful and I wouldn’t want to try and change anything about you.” The wife, touched by his honesty and the depth of his love for her and his acceptance of her, turned her head and wept.
In life, there are enough times when we are disappointed, depressed and annoyed. We don’t really have to go looking for them. We have a wonderful world that is full of beauty, light and promise. Why waste time in this world looking for the bad, disappointing or annoying when we can look around us and see the wonderful things before us?Why were there tears in the husband’s eyes when the wife read his annoyances?
| A．Because he had no courage to face his shortcomings. |
| B．Because he never thought he had so many annoyances in his wife’s eyes. |
| C．Because he was sorry that he didn’t find any annoyance about his wife. |
| D．Because he didn’t think he deserved to have such a perfect wife. |
After hearing the husband’s words, the wife felt _________.
| A．moved and ashamed | B．sad and disappointed |
| C．satisfied and proud | D．surprised and confused |
The story is intended to tell us that ___________.
| A．disappointment cannot be avoided in our life |
| B．young couples should be more tolerant (宽容的) to each other |
| C．we should turn a blind eye to other people’s blame |
| D．we should try to look for and see the wonderful things around us |

The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true.
Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air. Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time._______, our world is becoming much smaller.
| A．Because of the rise in pollution |
| B．Thanks to science development |
| C．Because the earth is being polluted day and night |
| D．Because the earth is blown away by the wind every year |
Hundreds of years ago, life was __________ it is today.
| A．much easier than | B．as easy as |
| C．much harder than | D．as hard as |

| C．air pollution | D．water pollution |
Air pollution is the most serious kind of pollution because _______.
| A．it makes much noise |
| B．it makes us angry more easily |

Which of the following is NOT true?
| A．Many countries are making rules to fight pollution. |
| B．The pollution of the earth grows as fast as the world population does. |
| C．The problem of pollution is not so serious because there are not so many people living on the earth. |

Some time ago, a friend of mine punished his three-year-old daughter for wasting a roll of gold wrapping paper. Money was tight（困窘的）, and he became infuriated when the child tried to decorate a box to put under the Christmas tree.

He shouted at her loudly, “Don’t you know that when you give someone a present, there’s supposed to be something inside of it?”
The little girl looked up at him with tears in her eyes and said, “Oh, Daddy, it’s not empty. I blew kisses in the box. I filled it with my love. All for you, Daddy.”
