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.
1.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
2.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.
3.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.

Some scientists believe that one of the most intelligent beings on Earth is in fact the octopus (章鱼).
Octopuses usually live at the bottom of river mouths and seas-areas which are not attractive to researchers. They are not social animals so it can be hard to study their interaction with others. And the octopus’ intelligence is not easy for humans to understand. When we observe some animals such as rats or dogs, we can often understand their behavior. Octopuses，however can seem like aliens (外星人). Scientists need to have a lot of imagination to understand what an octopus is thinking!
In the 1950s, the US Air Force sponsored scientists to study the way octopuses use their brains. They hoped that they could use this knowledge to help them build better computers. However, their brains were so complex that the scientists felt it of no significance to continue with it. Octopuses have a very complex nervous system and recent research suggests that they have some of their intelligence inside each arm, which means that each arm can “think” for itself. It also appears that they have a good memory, perhaps similar to a cat’s.
Perhaps the most striking thing about octopuses is their ability to change their color and body pattern. They do this to camouflage themselves to avoid their enemies and also to communicate with others. They can completely change their appearance in less than a second. It can change its skin to look like rocks, sand or planktron (浮游生物).
Some scientists have even suggested that these different patterns and colors are in fact a very hard language-and that each design is a different verb，adjective or noun. But nobody has been able to work out what they might be saying. There’s a long way to go to get to know the octopus completely.
1.What can we infer about the octopus’ intelligence from Paragraph 2?
A.It does not attract scientists. B.Little has been known about it.
C.It is equal to the cat’s or dog’s. D.Much has been done about it.
2.What can we say about scientists’ study on the octopus in the 1950s?
A.They had to give it up eventually. B.They used computers to help.
C.They found its arms could think. D.They judged it lived like a cat.
3.What does the underlined word “camouflage” in Paragraph 4 probably mean?
A.Relax. B.Strengthen. C.Hide. D.Express.
4.What does the author think of the octopuses?
A.They are the smartest animals. B.They’re easy to be seen in the sea.
C.It is useful to copy their language. D.It is difficult to understand them.

Many people believe that there is some truth in the saying Laughter is the best medicine.1. Laughter helps relieve pain, strengthen the immune system and reduce stress. Laughter stimulates(激发) hormones which make us feel happy. Laughter also increases the flow of blood throughout the body and has benefits which are similar to the ones you get by doing exercise.
2.Children exposed to funny films and cartoons before major medical procedures are able to cope better with pain and anxiety.3.. These are professional clowns who are sent to hospitals and wards to entertain and distract sick children.
Laughter therapy has become very popular in recent years and as a result, more and more laughter clubs are starting to open up in cities and towns all over the world. At a laughter session, a trained therapist instructs the group to perform a series of exercises which are designed to produce laughter. 4.And it takes them some time to get rid of their inhibitions（心理抑制）.They might even start off with fake laughter, but this doesn’t matter because our bodies can’t tell the difference, and the results are the same. Moreover, laughter is contagious（传染的).5.
So next time you feel ill, stressed out or depressed, try watching a funny film or try remembering an amusing incident in your life. You will soon feel better.
A. If one person starts giggling, it is unavoidable that everyone else will be drawn in.
B. Laughter helps you focus.
C. This finding has led to so-called clown doctors.
D. In fact, research done by scientists has shown that laughter has a lot of health benefits.
E. Laughter makes the world a better and more colorful place.
F. Some people may find the idea embarrassing at first.
G. Using laughter therapy in children’s hospitals has proven to be invaluable.

Some say every day miracles are predestined (注定的)---- All that’s necessary is readiness, the right circumstance for the appointed meeting. And it can happen anywhere.
In 1999, 11-year-old Kevin Stephan was a bat boy for his younger brother's Little League team in Lancaster, New York. It was an early evening in late July. Kevin was standing on the grass away from the plate, where another youngster was warming up for the next game. Swinging his bat back and forth, and giving it all the power an elementary school kid could give, the boy brought the bat back hard and hit Kevin in the chest. His heart stopped.
When Kevin fell to the ground, the mother of one of the players rushed out of the stands to his aid. Penny Brown hadn't planned to be there that day, but at the last minute,she had changed her shift (轮班) at the hospital, and she was given the night off. Penny bent over the senseless boy, his face already starting to turn blue, and giving CPR, breathing into his mouth and giving chest compressions (按压). And he came to life.
After his recovery, he became a volunteer junior firefighter, learning some of the emergency first-aid techniques that had saved his life. He studied hard in school and was saving money for college by working as a dishwasher in a local restaurant in his spare time.
Kevin, now 17, was working in the kitchen when he heard people screaming, customers in confusion, employees rushing toward a table. He hurried into the main room and saw a woman there, her face turning blue, her hands at her throat. She was choking .
Quickly Kevin stepped behind her, wrapped his arms around her and clasped his hands. Then, using skills he'd first learned in Scouts, the food that was trapped in the woman's throat was freed. The color began to return to her face.
“The food was stuck. I couldn't breathe,” she said. She thought she was dying. “I was very frightened.”

Penny Brown.
