As the population of the planet increases, so does the number of homes, businesses, parking lots, schools, airports and roadways. All these structures use electricity and need to be lighted. Humans demand these lights. They want their homes more comfortable and they want their streets safe. The problem is that researchers are finding that all the light is having a negative effect on humans and wildlife as well.

Less than 10 years ago I drove to a thinly populated section of my town, lay down in the middle of the road and watched an attractive meteor shower (流星雨). The area was short of homes, street lights and traffic. If I did that today, I wouldn't be able to see the meteor shower as well. Due to the increase in street lights, I would surely be run over by a car.

Nowadays scientists are finding light pollution can be almost as bad as carbon dioxide pollution. If you've ever taken a flight at night, the view is beautiful, but you must remember that all the light you see wastes electricity. The crew of the space shuttles see an even bigger picture of how extensive the wasted electricity is worldwide.

One of the saddest parts of light pollution is that most of it is unnecessary and most of the outdoor light that we use is wasted. One only needs to look at a row of street lights to see how much of the light shines upwards and lights the sky: a total waste of electricity.

Additionally, somewhere electricity needs to be produced, and the production of electricity creates pollution by releasing greenhouse gases. This affects the air we breathe and our quality of life.

Scientists are also studying the effects of light pollution on wildlife. Thousands of birds die each year when they crash into highly lighted buildings, as they become puzzled by the light. It has been long known that tiny baby sea turtles become lost and follow lights on the shore instead of heading towards the sea.

Fortunately, light pollution is one of the easiest sources of pollution that can be corrected without a negative effect. Following some guidelines and a little searching on Google can give you many ideas on how to reduce your contribution to light pollution.

1. It is implied in Paragraph 3 that the best way to deal with light pollution is ________.

A. reducing the output of the lights

B. avoiding the use of unnecessary lighting

C. educating people about light pollution

D. inventing environmentally- friendly lights

2.Which of the following is the effect of light pollution?

A. Many animals species have died out.

B. More traffic accidents happen every day.

C. The air we breathe may be polluted.

D. It is much easier for us to watch meteor showers.

3.What can be inferred from the text?

A. We are almost at a loss how to deal with light pollution.

B. Global warming results in light pollution in some way.

C. Astronauts can’t see clearly in space nowadays.

D. Some animals use natural light to direct their movements.

4.What will probably be provided following the last paragraph?

A. Helpful tips for surfing the Internet.

B. approaches to decreasing light pollution.

C. Benefits of searching on Google.

D. More bad effects of light pollution.

Do you have any problem with time? Start doing these and you will see the difference.

She had to stay in hospital, so we called her family. Soon his son came and thanked us by offering us money. We refused money and left. Hurried to school, we found we were late.

Michelle was a student at University of California, Los Angeles. She is here to tell us how she feels about the city.

What were the best things about Los Angeles?

One of my favorite things about Los Angeles is the weather. I hate the cold and it never really gets that cold there. Plus, most of the time it’s usually sunny, which is good because I love going to the beach during the summer. There’s so much to do at the beach, but my favorite thing in L.A. was having a picnic on the sand with my friends.

What were the worst things about being there?

I disliked having to drive everywhere to get around because the city is so spread out. Los Angeles has a lot of traffic and sometimes it takes a long time to get somewhere close by just because the streets are so crowded. Also, a lot of people complain about the pollution.

Did you have any problems there?

Just the normal problems of living in any city, like watching out for pickpockets (扒手). Some people think Los Angeles has a lot of crime, but I think it’s as safe as any other city. Also, many people think driving is difficult because there is a lot of traffic and road rage (路怒癥), but it just takes a little practice and a lot of patience.

What are the people like in Los Angeles?

There are all types of people in Los Angeles since the city is pretty diverse. For the most part, though, most of the people are friendly, calm and relaxed. Some people say that everyone in Los Angeles is beautiful, but I think that’s just a stereotype (模式化的印象).

Would you go back to Los Angeles?

Certainly. Los Angeles is one of my favorite cities in the world. I love the fact that it has all the nightlife and shopping of a big city, but also has access to beaches, parks, mountains and other places you can’t usually find in large cities. Between the weather and the beaches and all the fun things to do, it’s a great place to be.

1.We can learn from the text that Michelle _____.

A. hates the heavy traffic in Los Angeles

B. dislikes the cold weather in Los Angeles

C. thinks Los Angeles is small and crowded

D. enjoys driving everywhere in Los Angeles

2.What’s Michelle’s impression of the people in Los Angeles?

A. They get angry easily.

B. All sorts of people live there.

C. They are patient and amusing.

D. Everyone is kind and beautiful.

3.How does Michelle find Los Angeles?

A. Safe but noisy. B. Relaxing but busy.

C. Polluted and dangerous. D. Diverse and interesting.

4.We learn from the text that _____.

A. Michelle was born in Los Angeles

B. Michelle loved the life in Los Angeles

C. Los Angeles has many traffic accidents

D. Michelle has no plan to return to Los Angeles

科目：高中英語(yǔ) 來(lái)源：2015-2016學(xué)年福建長(zhǎng)泰縣二中高一下期第一次月考英語(yǔ)試卷（解析版） 題型：閱讀理解

Sports are all about change. A team gets better. A kid practices more and swims a personal best or learns a new move on the basketball court. In 2006, two things happened that got me thinking about change—in sports and in life.

One of them is tennis champion Andre Agassi, who retired in 2006. Agassi was a terrific player who won 60 titles, including eight major championships(冠軍稱號(hào)). But his greatest accomplishment（成就）might have been how much he changed during his career.

When he was young, Agassi was a show off who seemed to care only about himself. He didn't train very hard, but he won matches because of his tremendous（極大的）talent.Eventually, though, injuries and his bad attitude caught up with him. He fell from No.1 in the world ranking to No.141.

So Agassi changed. He trained harder and became a world-class player again. More importantly, he changed as a person. He was nicer to fans and opponents（對(duì)手）. He stopped thinking just about himself and started thinking about others. Through his Andre Agassi Charitable Foundation, he raised more than $60 million to help disadvantaged kids around his hometown of Las Vegas, Nevada. He even started a school, the Andre Agassi College Preparatory Academy, for at-risk kids.

At the start of a new year, lots of people promise themselves they will change. They might vow to get in good physical shape, do better in school or be nicer to others. Changes such as those can be difficult. But they do happen. Just remember Andre Agassi: It wasn't easy, but he changed, and changed for the better.

1.According to the writer, which of the following may be the greatest achievement for Agassi?

A. He once ranked No.1 in the world rankings.

B. He won 60 titles.

C. He changed much during his career.

D. He won 8 major championships.

2.What does the underlined work “vow” in the 6th paragraph probably mean?

A. promise. B. agree. C. wish. D. prove.

3.What do you know about Andre Agassi Charitable Foundation?

A. It is intended to help at-risk kids.

B. It is a charity school set up by Agassi.

C. Some disadvantaged kids can get help from it.

D. Agassi runs it with his prize money.

4.What might be talked about in the paragraphs following this passage?

A. What achievements Agassi has made after he changed for the better.

B. How we can change for the better.

C. Another thing happened in life that got the writer thinking about change.

D. Some assessments(評(píng)價(jià)) about Agassi from different people.
