I once experienced an unforgettable trip to Gloucester to see some of the world’s most beautiful and exciting animals in their own habitat(栖息地), the North Atlantic Ocean.
After a long trip by bus, we got on the ship. After a while, we stopped and everyone began to shout because we saw a humpback whale（座头鲸）. It was wonderful. Sometimes, whales came so close to the ship that you thought you could easily touch them.
While we were watching the whales, a guide was giving us some information about them, She told us that we saw only two kinds of whales- 50 foot humpback whales (singing whales) and 70-foot finback whales(the second largest whales on earth). She also said we could easily recognize a whale by its tail because every whale has a different kind of tail just like people have different fingerprints.
They all have names,and on this trip we saw “Salt” and “Pepper”, two whales named by a biologist and a fisherman. They were swimming toghter all the time.
I took twenty-seven photos,but it was very hard to take them because the whales were quick and stayed on the surface of the ocean just for a short time. It was really something. It was one of the chances that a person hardly ever experiences in life, but I had that chance.
This passage is mainly about _________________.
A an unforgettable experience in the forest

Everyone on the ship began to shout because_____________.
A a whale came so close to the ship

The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait,where killer whales are found on a daily basis each summer.It is strongly recommended that vessel(船只)operators follow these guidelines for all kinds of whales.
Approach whales from the side,not from the front or the back.
Approach no closer than 100 metres,then stop the boat but keep the engine on.
Keep noise levels down-no horns,whistles or racing of engines.
Start your boat only after the whales are more than 100 metres from your vessel.
Leave the area slowly,gradually moving faster when you are more than 300 metres from the whales.
Approach and leave slowly,avoiding sudden changes in speed or direction.
Avoid disturbing groups of resting whales.
Keep at low speeds and remain in the same direction if travelling side by side with whales.
When whales are travelling close to shore,avoid crowding them near the shore or coming between the whales and the shore.
Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales.
If there is more than one vessel at the same observation spot,be sure to avoid any boat position that would result in surrounding the whales.
Work together by communicating with other vessels,and make sure that all operators are aware of the whale watching guidelines.
For whom is this text written?
| A. Tour guides | B. Whale watchers |
| C. Vessel operators | D. Government officials |
When leaving the observation areas, the vessel should ________________.
| A. move close to the beach | B. increase speed gradually |
| C. keep its engine running slowly | D. remain at the back of the whales |
When going side by side with whales, the vessel should ________.
| A. keep moving in the same direction | B. surround the whales with other boats |
| C. travel closer and closer to the shore | D. take a good viewing position |
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(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.
C. The decibel is not a right unit (单位) for measuring underwater noise.
D. Different ocean animals may have different reactions to noises.
4. 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 high-level noises.
D. Their hearing will be damaged by high-level noises.
5.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 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.

It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently. My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. I’m so glad I did.
On the road to the harbor we could see the terrible destruction on the coast, but the harbor itself was in fairly good shape. After all, it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big humps(脊背) in the distance.
On approaching them, we saw it was a mother whale with her baby. We couldn’t believe it — there aren’t any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.
The little baby whale — actually as big as our boat — was obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools(漩涡) and waves. “She’s trying to help her baby, but on the wrong side,” my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, some-times rising from the water right beside us to breathe — and to give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.
In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day. Nearly four decades later, I still look back fondly to that golden day at sea.
