But the busy environment found at an airport can cause dogs ants in their pants even the best trained working ones. People with disabilities depend on their dogs. They want the animals to safely guide them through safety areas. They also need the dogs to remain calm on duty on the airplane, even when the flying is not smooth. This takes special training.

The Air Hollywood K9 Flight School is one place where such help can be found. The school has a piece of equipment（设备） that provides the sights, sounds and even the feel of an airplane in flight. Dog trainers say training is based on a simple rule: preparation. Dogs need to be trained gradually to the environment, to loud noises, to sounds and other dogs so that when this experience happens to them on a daily basis, they're able to act in a way that they're used to acting and that they don't get excitable.

We go to school every day to become better people. How can we start to make big changes in our lives? Perhaps we can get tips from former US First Lady Michelle Obama. During a visit to China from March 20 to 26 in 2015, Obama shared her views on education.

The first lady encouraged Chinese students to aim high and get a good education. At Chengdu No.7 High School, she told students that having humble roots（出身卑微）doesn’t matter as long as you have perseverance（毅力）. Obama said her family was not rich. Like many Chinese students, her parents had big dreams for her. She felt the weight of her parents’ sacrifices（牺牲）on her shoulders and worked hard to make them proud. Persevering was not easy, though.Sometimes she had to wake up at 4:30 am and study late into the night“But whenever I got tired or discouraged... I would remember something my mother always told me. She said: ‘A good education is something that no one can take away from you.

Mrs. Obama also encouraged Chinese students to study abroad to broaden their horizons（开阔视野）in a speech at Peking University.“ AS the Chinese saying goes:It is better to travel 10.000 miles than to read 10.000 books.” she said. It's not enough to get good grades in school.It’s also important to have real experience with languages, cultures and societies that are different from your own, she noted. Studying overseas can also benefit future international relations. It can help young people from different countries work together to solve shared problems like climate change, Obama said.

Noise pollution is doing much harm to our health now. Noise，in fact，is unwanted sound and is a kind of invisible (无形的) killer. More and more students enjoy listening to music very much. When they listen to MP3 players, they like to turn up the volume (音量)．Some people love listening to loud music. Furthermore, while watching TV, they keep the volume up. But they haven't realized that the noise is weakening their hearing. In fact, the noise not only influences each member in the family, but also makes a difference to the comfort of neighbors.

Noise pollution is a source of increasing misery (痛苦) to people in our society. If people are often disturbed by it, they may feel uncomfortable or upset. What's worse, the noise can make people mad sometimes. If a worker works in a printing factory for too long, his/her hearing loss is much faster than a common person working in a quieter environment. So everybody must pay more attention to noise pollution. Generally speaking，the following four types of noise should be watched out for：

◆Noise in the street

◆Construction site (建筑工地) noise

◆Noise at work

◆Transportation noise

I think the local department (部门) should take measures to control the noise levels, but it's everybody's duty to keep a quiet environment.

1.Why is noise called a kind of invisible killer?

A. Because we can't see it with our own eyes.

B. Because it's really harmful to our health，but people don't realize it.

九年级英语单选题中等难度题查看答案及解析

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.
