Today there are many fires than in the past. Over 100,000 wildfires burn each year in America. Russia has 20,000 to 35,000 wildfires every year. Australia has on average 60,000 each year. These fires destroy（損害）huge areas of forests and burn hundreds of homes.

Many experts believe there are several reasons for this sudden increase in fires. The first reason is climate（氣候）change. Recent weather has been warmer and drier. This leads to dangerous fire conditions. When lightening strikes（發(fā)生雷電），dry grass easily catches fire. Hot winds add to the problem. The wind spreads a fire quickly. In 2010, Russia had the hottest and driest summer in a century. In just one month, 500 fires destroyed over 2,000 homes. Some people lost their lives.

Traditional fire-fighting practices are another reason for the increase in fires. In America, firefighters used to quickly put out every fire. They didn’t allow the grass and trees to burn. As a result, today many forests have thicker vegetation（植被）.Thicker vegetation means more fuel（燃料）for fires. Also, without fires from time to time, forests become overcrowded and unhealthy. Some trees are dead. The dead wood then easily catches fire. So surprisingly, America has many more fires today partly because of its past fire-fighting practices.

Scientists now understand that a fire can be a natural part of a healthy forest. As a result, countries like Australia allow more fires to burn naturally. Sometimes, fire fighters even start fires to get rid of（去除）dead wood. Of course, they carefully control the fires. The fire thins out old trees. This allows sunlight to reach the ground. As a result, fires help new trees to grow. Therefore, if a fire is not a serious threat（威脅）to people, firefighters may let it burn naturally.

1.Why did Russia have so many fires in one month in 2010?

A. Because lightening spread the fire.

B. Because there was much fuel for fires.

C. Because there were not enough firefighters.

D. Because it was unusually hot, dry and windy.

2.What happens because of the traditional fire-fighting practices in the USA?

A. There are fewer wildfires.

B. Trees and grass become thicker.

C. The weather becomes warmer and drier.

D. Sunlight reaches the ground to help forests.

3.What is the main idea of Paragraph 4?

A. Fires are serious threats to human beings.

B. Australian firefighters don’t put out fires.

C. Fires can play an important role I forests.

D. It’s difficult for firefighters to control the fires.

4.Which of the following is true according to the passage?

A. Not all the fires in the forests must be put out.

B. People’s carelessness leads to dangerous fires.

C. Australia allows all the fires to burn naturally.

D. There are more fires in Russia than in the USA.

(2013溫州)

It is widely agreed that the overuse of fossil fuels，such as coal and oil has caused serious environmental problems．Scientists are trying to find new clean energies that do not pollute the air，the water or the ground．Solar power is one of them．

Solar power is a kind of electricity which is produced by taking energy from the sun，using solar panels．The solar panels are usually fixed on the roofs of houses and buildings．It is the family solar power system．Some countries are even beginning to build solar power plants by setting thousands of solar panels in the places where there is enough sunshine．Solar power has many advantages．The power is easy to get and will never be used up．Whenever it is sunny，there is the power．The power is clean and renewable．It helps to reduce waste and pollution，which is great for the environment．In the areas that are too far away to send electricity to or not easy to build electric power plants，solar power is especially necessary．It enables the people there to use lights，TVs，computers，washing machines，fridges and many other things．

Therefore，more and more countries，such as China，the USA，Japan and India，encourage scientists to develop practical technology to put solar power to use．However，the power is not as widely used as expected．

One of the challenges is that a solar power system needs sunshine．Countries or areas with a lot of rain，like the UK，are not suitable to develop such power systems．Secondly，a solar power plant requires a very large site to fix enough solar panels to collect sunlight and change it into electricity．Maybe an area in the desert would be one of the perfect places for such a plant to build．What’s more，solar panels are expensive at present though the energy itself doesn’t cost anything．

Today scientists are working hard to develop more practical and cheaper solar power systems．Maybe one day solar power will be one of the most important clean energies in our life．

1.Solar power is a kind of energy taken from________．

A. the air

B. the sun

C. the water

D. the ground

2.The underlined word“reduce”probably means________．

A. to make something less

B. to make something better

C. to make something more

D. to make something cleaner

3.What is the fourth paragraph of the passage mainly about？

A. The ways to use solar power．

B. The advantages of solar power．

C. The places to build the solar power plants．

D. The difficulties of putting solar power to use widely．

4.What can we learn from the passage？

A. Solar energy itself is expensive．

B. Solar power will be used up very soon．

C. Solar power is a kind of clean and useful energy．

D. Solar power is much better than the other energies．

It is believed in some ways that the daughter is father’s lover. But my experience has taught me in a different way. For a long time, my father has been a very vague figure（模糊的形象）to me. He was a man of few words, tall but slim and nothing else.

When I was in primary school, my father was never there to pick me up, and he never came to any of my parent-teacher meetings. He was always busy doing projects. I remember when I was in middle school and my head was badly hurt in a PE class. During my operation, my father was nowhere to be found. This hurt me most. At that moment, I considered my father as a cold-blooded man who did not care about me at all.

But things seemed different at my high school graduation ceremony, where I was chosen to represent my class and give a speech. My father, once again, told me he had a business trip in a place outside the city and would be unable to show up（露面）. “Don’t come. I will be very nervous if I see you,” I told him.

I remember my speech went smoothly. After the ceremony was over and I was about to leave. I suddenly noticed a familiar（熟悉的）looking man sitting in a corner of the hall. It was my father! I was so surprised that I rushed to him with tears（眼淚）running down my face. “Well done,” he said. His eyes were also filled with tears.

Later, I found out that my father had managed to finish his work by staying up late, and he drove for eight hours to get back. He had been sitting in the corner because he didn’t want me to see him. My father remembered every word in my speech.

For much of my life, I described my father was a cold-blooded man who only cared about his work. But when I thought deeply aboutthis, it was obviously（明顯地）not true. At my graduation ceremony. I could feel my father’s deep love. The fact is that seeing is not believing, and seeing may not be the fact if we don’t perceive（感知）the world with our hearts and minds. There’s no doubt that life doesn’t lack（缺少）love, but sometimes our eyes have trouble seeing it.

1.Which of the following is TRUE according to the passage?

A. The writer’s father was in the hospital during her operation.

B. The writer’s father attended her high school graduation ceremony.

C. The writer’s father sometimes picked her up when she was in primary school

A. she gave a speech successfully

B. the graduation ceremony was over

C. she was so nervous that she couldn’t help crying

D. she was touched to find her father cared about her

3.What does the underlined word “this” in the last paragraph refer to（指代）?

A. That my father was always doing projects.

B. That my father was a cold-blooded man.

C. That my father sat in the corner of the hall.

D. That my father’s eyes were filled with tears.

4.What’s the best title of the passage?

A. My busy father B. Life is full of love

C. Seeing is not believing D. A wonderful speech

Did you know that each day one person in the US throws away 4.4 pounds of rubbish? Almost every month, we throw away our own rubbish in packaging alone. Packaging ( including boxes, bags, etc) comes to our homes with the things we have bought. Several weeks ago, the TV news said that in a city in Italy, tons of rubbish were piled up in the streets, and the smell was rather terrible. What can we do to help? We should get to know the following Rs.

To reduce means to make less rubbish That is one of the first things we all should do for the environment. Reduce your rubbish by doing things like packing your lunch in reusable containers(可再利用的容器)，taking smaller potions(份)at dinner so you don't waste food when you have had enough, writing on both sides of paper, and using less water when taking a shower.

To reuse is to use things again. Think about the bags you get from the store. They can be reused to carry your lunch, to hold your rubbish, or to collect used cans. You can even take them back to the store the next time to carry your things instead of getting a new bag!

Recycling is an important part of keeping our planet clean and green. It can also save energy. Be sure that you don't throw things in the rubbish that can be recycled to make something else. Paper, plastic, cans and bottles can all be recycled, but food, electrical waste and mobile phones can't. When you are not sure whether something can be recycled, go to your parents and teachers for advice.

Follow the three Rs, and every one of us can do something to save the Earth. It is also the best way to save ourselves.

1.The first paragraph of the passage implies(暗示) that .

A. packaging should be given up

B. Italy is too dirty for us to visit

C. the US produces most rubbish

D. the Earth is becoming dirtier

2.The writer seems to ask people to reuse the bags .

A. only as rubbish bags

B. only for carrying other things

C. mainly to have a cleaner world

D. mainly to save some money

3.Which of the following can be recycled?

A. Food and bottles.

B. Books and newspapers.

C. Paper and mobile phones.

D. Plastic and electrical waste.

4.The passage mainly tells us that .

A. all useless things can be recycled

B. the environment is greatly improving

C. the three Rs can help us clean the Earth

D. we should never throw any rubbish away
