Alternative Sources of Energy
The world's number one energy source is not man-made. It is much bigger than anything that Man could ever dream of designing or manufacturing, and in fact produces all the energy needs of everybody on Earth.1.. Apart from it, other energy sources are being exploited by Man to facilitate the development of the modern civilization.
Solar Energy
Solar energy is a simple and already familiar source of more direct renewable energy production. Its use is on the increase as technology improves.2.. In India there are plans to power 100,000 villages and install 500,000 solar powered telephones. During the course of one year, Europe receives approximately 1000-kilowatt hours of solar energy each square meter.
Water Energy
Water power is used in countries that have a lot of natural rivers and streams.
3., because in order to generate hydroelectric power, engineers must first build a dam to block a river and create a reservoir. Power is generated as the water flow from reservoirs is directed to turn turbines and electric generators.
Wind Energy.
4.. Many countries have also traditionally used wind as a source of power by building windmills. Some windmills even have been used for more than a century, but there has been a significant increase since the 1970s. They are already a familiar sight in Netherlands, Denmark and on windy islands such as Las Palmas in the Canary Islands.
Of course there are many other alternative sources of energy (geothermal power, tidal power, etc.), which are currently being researched and used in countries around the world. These sources often create less pollution than traditional sources of power and are becoming more economical to use as technology improves.5..
A. Solar energy is said to keep down the costs of maintenance and energy.
B. It is happening in both developed countries and emerging economies like India.
C. The best source of energy is wind energy.
D. They are the logical choice towards a more environmentally conscious planet.
E. That energy source is by all means the Sun.
F. Another form of energy with us for centuries is the use of wind power.
G. Some environmentalists claim that this type of power can be hazardous to local ecosystems.
One day, “supercharged plants” may help feed people around the world. Supercharged plants are ones that grow faster than normal plant life. Scientists can speed up the growth by modifying, or changing, the structure of plants' genes. The modifications make them react quickly to changes in light. This all has to do with photosynthesis(光合作用), the process in which plants turn sunlight, carbon dioxide and water into food.
Plants grow fastest in the sun. That is when they make the most food for themselves. But their rate of growth can slow when things like clouds or trees block sunlight. But when the sun returns, it can take many minutes for growth to speed up again.
This can be a problem because it means some of our most important crop plants are not as productive as they could be. Researchers say demand for food is expected to increase up to 70 percent by the middle of the century. They also note rising temperatures on Earth's surface. That is why they are looking for ways to improve photosynthesis and make plants more productive.
Steve Long is a plant biologist at the University of Illinois. He wanted to find a way to help plants get back up to speed quickly after a period of darkness. So he and his team added genes that shortened the recovery time. It also increased the speed at which the plants grew. His modified plants grew up to 20 percent more than untreated ones.
In Long's study, his group used a form of genetic engineering called transgenics (转基因). It means taking genes from one plant, then putting them into another. Now they are experimenting soybeans, rice, cowpeas and cassavas.
1.What is the advantage of supercharged plants?
A. They can grow more quickly.
B. They can grow in severe conditions.
C. They can offer high-quality grains.
D. They can replace normal plants.
2.What can make plant growth slow down?
A. Too hot weather. B. Old farming methods.
C. Lack of sunlight. D. Too much sunlight.
3.What was Steve Long's goal in his study?
A. To find out what makes plants grow slowly.
B. To create a new plant that can grow with weak sunlight.
C. To find another way to help plants benefit each other.
D. To make plants recover quickly when the sun returns.
4.How can researchers shorten the recovery time of plants?
A. By changing their nature. B. By adding new genes to them.
C. By developing new plants. D. By supplying more sunlight.
When I was watching some children attempting to catch butterflies on a hot July afternoon, an incident in my own childhood occurred to me. When I was 15, something happened to me, which forever cured me of desiring to put any wild life in a cage.
We lived on the edge of a wood, and every evening at dusk the mockingbirds would come and rest in the tree and sing. There isn't a musical instrument made by man that can produce a more beautiful sound than the song of the mockingbird.
I decided that I would catch a young bird and keep it in a cage and that way have my own private musician.
I finally succeeded in catching one and put it in a cage. At first, in its fright at being captured, the bird fluttered about the cage, but eventually it settled down in its new home, I felt very pleased with myself and looked forward to some beautiful singing from my tiny musician.
I had left the cage out on our back porch(门廊), and on the second day of the bird's captivity my new pet's mother flew to the cage with food in her mouth . The baby bird ate everything she brought to it. I was pleased to see this. Certainly the mother knew better than I how to feed her baby.
The following morning when I went to see how my captive was doing, I discovered it on the floor of the cage, dead. I was shocked! What had happened? I had taken excellent care of my little bird, or so I thought.
Arthur Wayne, the famous ornithologist, happened to be visiting my father at the time and, hearing me crying over the death of my bird, explained what had occurred: “A mother mockingbird, finding her young in a cage, will sometimes bring it poisonous berries. She thinks it better for her young to die than to live in captivity.”
Never since then have I caught any living creature and put it in a cage. All living creatures have a right to live free.
1.Why did the writer catch a mockingbird when he was a boy?
A. He had just got a new cage.
B. He liked its beautiful feather.

D. He wanted a pet for a companion.
2.Why did the mocking bird die?
A. It was frightened to death.
B. It drank the poisonous water by mistake.
C. It ate the poisonous food its mother gave it.
D. It refused to eat anything.
3.What is an ornithologist likely to be?
A. A specialist in birds. B. A religious person.
C. A headmaster. D. A considerate person.
4.What is the most important lesson the author learned from the incident?
A. Be careful about the food you give to baby birds.
B. All birds put in a cage won't live long.
C. You should keep the birds from their mothers.
D. Freedom is very valuable to all creatures.
