Scientists around the world have been studying the warming of waters in the Pacific Ocean known as El Nino. The appearance of El Nino is known to affect the weather around the world. Scientists still do not completely understand it. Yet they now find they can use it to tell about the future in different areas of the world.

One example is the work of two scientists at Columbia University in New York, Mark Cane and Gordon Eshel. A scientist of Zimbabwe（津巴布韦）, Roger Buckland worked with them. They have found that when El Nino appears, Zimbabwe has little or no rain. This means corn crops in Zimbabwe are poor. The last El Nino was in 1991 to 1993. That was when southeastern Africa suffered a serious lack of rain.

The scientists wrote about their recent work in the publication Nature. Their computer program can tell when an El Nino will develop up to a year before it does. They suggest that this could provide an effective early warning system for southern Africa, and could prevent many people from starving.

1.El Nino is known as ________.

A. the changing of the weather in southern Africa

B. the weather which brings drought (旱灾) to Africa

C. the warming of waters in the Pacific Ocean

D. the weather phenomenon that brings heavy rains to Africa

2.Scientists study El Nino in order that ________.

A. they can put all this information into their computers

B. they can tell why Zimbabwe has little or no rain

C. they can do some research work in this field

D. they can provide a kind of early warning to the place that will suffer from drought

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

A. Scientists come to understand how El Nino appears.

B. Three scientists from the USA work on this subject.

C. El Nino has something to do with Zimbabwe’s poor crops.

D. Southern Africa suffered a serious drought and many people died from hunger.

Scientists in Mexico have just begun a new study of one of the world’s biggest pyramids: the Pyramid of the Sun, north of Mexico City. They’re putting lots of small, high-tech machines under the pyramid to try to unlock some of its secrets. For thousands of years, people have tried to uncover the secrets of the pyramids.

The people who built the pyramids made lots of secret doors and rooms to stop robbers from finding the treasures inside. However, there always have been some smart thieves in history. Now, almost all of Egypt’s pyramids have been robbed, including the Great Pyramid of Khufu, which is the largest pyramid in the world. It is the only one of the ancient wonders of the world that is still standing.

In AD 820, an Arab king named Abdullah AL Manum got a group of workers to dig their way into the Great Pyramid and have a look. Inside the pyramid, they found three rooms --- the Queen’s Chamber, the Grand Gallery and the King’s Chamber. But to their surprise, the men didn’t find the treasures they wanted. The Queen’s and King’s Chambers were both empty! Where were the King’s mummy and his treasures? Had someone already taken them away? The huge stone doors at the pyramid’s entrance were still closed when AL Manum’s men went inside. How had the thieves got in and out?

Since then, many people have gone inside the Great Pyramid to have a look or to try to take things. But still, no other chambers or walkways have been found.

In 2002, an American team made the most recent visit to the Great Pyramid. Scientists sent a robot into the pyramid, but they only found a mysterious locked stone door.

1.The first two paragraphs were written to show that ________.

A．the Pyramid of the Sun is an unusual historic building

B．ancient Egyptian emperors were cruel

C．construction workers led a hard life in ancient Egypt

D．the secrets of the pyramids remain to be uncovered

2.What is the purpose of making some secret doors to the pyramids?

A．To try to unlock some of its secrets.

Scientists, doctors and mental health professionals have been studying the connection between colors and mood for years. Many now believe that colors can not only bring about emotional reactions, but can also correct mood. Colors behave in three basic ways: active, passive and neutral (中和的).

Active colors are warm colors, including yellow, orange and red. These colors bring confidence. Warm colors can also bring cheerful attitudes. Yellows and golden colors work well in offices, kitchens and study areas. Reds heat up a room. Passive colors or cool colors make people calm, quiet and satisfied. Bedrooms, private areas and bathrooms are great places for blues and greens. Beige, gray and white are thought of as neutral colors. They help to put the focus on other colors or serve to tone down colors that might otherwise be overpowering on their own.

You can easily change the look or feel of a room by making good use of different colors. Mixing and matching colors is an excellent way to balance color and emotion, and provide a welcoming feel for guests.

To create a feeling of warmth and comfort in a room, use bright, warm colors like yellow, orange and red. These colors are good choices for rooms that appear cool due to limited sunlight. Yellow adds cheerfulness to dull rooms. You can add yellows to rooms which are not closely related to happy thoughts, such as kitchens and laundry room. In rooms where there's plenty of sunshine, cool colors can provide a calming environment. Sage greens and sky blues are perfect for bedrooms, playrooms and activity areas. Neutral colors, such as pale gray, white and beige, send a peaceful message to your brain. It's not a coincidence that most doctor's offices, coffee shops and mental health centers are decorated in neutrals.

To make your wall color choices better, pick out furniture that will provide a visual contrast. Cool colors make a room seem larger than it is and warm colors make rooms feel smaller.

Title: The 1. ____________ between colors and mood

Wind farms have been considered as the way to fight global warming, but a new study suggests they could actually heat the planet up.

The study found that the US would get warmer if the number of turbines(涡轮机）were increased markedly. Researchers say they'll require much more land than previously thought, needing five to 20 times more space than earlier studies have suggested. And winds created by vast fields of turbines could mix warm and cool air, which makes the surface quite warm .

Despite the potential drawbacks, however, the researchers argue wind energy still makes more sense for the environment than fossil fuels. Study coauthor and Harvard University scientist Professor David Keith argued that, when it comes to energy production, there is no free lunch. "Wind beats coal by any environmental measure, but that doesn't mean that its effects can be ignored. We must use fewer fossil fuels to stop carbon production. In doing so, we must make choices between various low-carbon technologies , all of which have some environmental effects , " he said.

More than ten previous studies have now observed local warming caused by US wind farms. Researchers suggested that solar power offers a less damaging energy source in the fight against climate change. In terms of temperature difference per unit of energy generation, solar power has about 10 times less effect than wind, and the solar power energy is mature in a wide range of fields. But there are other considerations. For example, solar farms are dense(密集的）, while the land between wind turbines can be co-used for agriculture.

Tidal power is an environmentally-friendly energy source. In addition to being a renewable energy, it does not give off any climate gases and does not take up a lot of space . However , there are currently very few examples from real tidal power plants and their effects on the environment. Also, it is important to realize that the methods for generating electricity from tidal energy are relatively new technologies. It is projected that tidal power will be commercially profitable within2030 with better technology and larger scales.

1.What is the purpose of the text?

A.To introduce a study finding.

B.To discuss the global warming problem.

C.To prove the benefits of wind farms.

D.To call attention to environmental protection.

2.What is paragraph 2 mainly about ?

A.The effects of global warming.

B.The reason for using wind energy.

C.The disadvantages of wind farms.

D.The working principle of wind farms.

3.What do Professor David Keith's words suggest?

A.Producing energy is easier than before.

B.Consuming energy damages the environment.

C.Burning coal should be totally stopped.

D.Developing low-carbon technologies is hard.

4.Which is recommended considering the environment and practical use?

A.Wind energy. B.Fossil fuel.

C.Tidal power. D.Solar energy.

Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness(利用) usable wind energy produced by man-made technologies.

One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can be transformed into electricity.

According to Pradhan’s proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts(兆瓦) of electricity could be harvested each day.

Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device(装置) called T-Box that harnesses wind energy from speeding trains.

T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers(水泥枕木), which does not disturb the normal train operating at all. According to Yanko, around 150 T-Boxes can be fitted along a 1,000-meter railway track.

A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box’s design won a silver medal in last year’s Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei, Taiwan Province.

Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn’t taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance(维护) of the device.

We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.

1.What can we learn about T-Box?

A. It will be fitted on the trains.

B. It is based on Pradhan’s idea.

C. It can turn electricity into light.

D. It was invented by an Indian scientist.

2.How much electricity can be produced per day by T-Boxes along a railway track of 100km?

A. 260 KWH.　　　 　　 B. 2.6 KWH.

C. 150 KWH.　　　 　　 D. 1.5 KWH.

3. It can be concluded from the last two paragraphs that ______.

A. T-Box has proved to be effective in harvesting wind

B. the maintenance of T-Box will be costly

C. there is much to do about T-Box

D. T-Box will come into use soon

4.According to the passage, which of the following statements is TRUE?

A. The Indian inventor Santosh Pradhan invented the speeding train.

B. The T-Box’s design won a silver medal in Lite-On Awards last year.

C. Rail travel has become one of the energy-efficient technologies in the world.

D. The India harvests 10,000 megawatts of electricity each day on average.

5.The passage is mainly written to _______.

A. encourage more people to travel by train

B. explain the advantages of electricity

C. tell readers how to save energy and money

D. introduce a new invention to readers
