My mother is a teacher, and I grew up with the challenges (挑战) a teacher faces. I often asked her, ”Why do you teach? What keeps you teaching? "The answer was always the same. "There is always that one child, that one moment that is worth it.”

Now, I am a teacher, too. But different from my mother, I teach students challenging activities outdoors. And when my mother asked me the similar questions, my answer was, "it's that one child, that one special moment.”

One of those moments happened recently. I was working with a group of girls in a four-week programme. Everything went on well through the "Team" events and we were moving on to a "High" one called the wire（钢索） Walk．

In the Wire Walk, each girl had to climb up the pegs(木桩)in a tree to a wire, 8 meters high, and then walk across it. Of course, everything was safe for sure.

When I asked who would try, a few girls raised their hands, and they finished the Wire Walk with little difficulty.

But when it was Susie’s turn, it seemed that she didn’t really want to. I asked Susie if she was ready. She Answered softy, “I suppose.”

Now, Susie was at the foot of the tree. She started to make the long reach for the first peg. The other girls cheered for her. Then I found Susie was becoming nervous with every step. I realised she would not go much further.

Susie was halfway up. Then she stopped and held the tree tight(紧紧地), looking very afraid. Her eyes were closed. With her face against the tree, she cried, “I can’t.”

The other girls sat in silence. I talked quietly to Susie, trying to relax her. I talked for a long time till I ran out of words.

“I will still be your friend no matter what, Susie!" Mary broke the silence.

To my surprise, Susie lifted her head and looked up to the wire. Then she turned to look down at Mary and smiled. Mary smiled back.

Finally, Susie made it all the way across that wire. When she returned to the ground, the first hug she looked for was from Mary.

We all cheered.

Moments like this keep me doing what I do. The young hearts continue to fill me with courage.

Some scientists say that animals in the ocean are

increasingly threatened(威胁) by noise pollution caused by

human beings. The noise that influences sea animals comes

from a number of human activities. It is caused mainly by

industrial underwater explosions(爆炸) , 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（效果）.

Some scientists have proposed setting a noise limit （限度）of one hundred and twenty decibels in 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.

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. It’s time for them to take action to help ocean animals.

1.Which of the following is not caused by human beings?

A. The noise of industrial underwater explosions.

B. The noise of ocean drilling.

C. The sound of underwater earthquakes

D. The noise of ship engines.

2.What does the second paragraph mainly tell us?

A. The same noise measures differently on land and in the ocean.

B. Different places may have different types of noises.

C. The noises can cause humans to lose hearing.

D. There are different kinds of natural sounds in the ocean.

3.Which of the following statements is TRUE?

A. Powerful underwater explosions aren’t harmful to whales’ ears.

B. Many researchers are against the noise limit of 120 decibels.

C. Noises cannot cause whales’ death.

D. The noise limit of 120 decibels would hardly influence the industrial research.

4.According to the passage, we can infer that scientists will probably .

A. work hard to cut down natural sounds.

B. stop industrial and scientific research in oceans.

C. try their best to make no noise.

D. protect ocean animals from harmful noises.
