摘要:How long will the sun run for ?

Our environment isn’t as green and beautiful as it should be. There are steel monsters blocking out the sun, blowing out dangerous smoke, and letting out poisonous chemicals into rivers, cars producing harmful waste gas, people throwing out waste in a wrong way and all other kinds of sources that ruin the planet. Facing current environmental problems, people need to do their best to save the Earth.
You can see many big garbage dustbins in the streets. They’re not there for a show, but for you to drop your waste. We should realize that what a little we do does count. So next time you get that urge to throw gum or a chocolate package out of the car window, or “ accidentally” drop as you walk down the street, ask yourself how much waste you’ve been contributing to the environment with that bad habit going on for years.
At home, the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps(水龙头)are not leaky(泄露的),which would help greatly in scrimping. Another is to use energy-saving lights, and turn them off before you leave the rooms. It’s not only energy-saving, but also cuts down electricity costs.
Recycling is a method to make items reusable. Many things you want to throw out can be made into new products through the reproducing process. Use your imagination to come up with ways on things that you can use again.
Pass the message of simple ways to save the environment on to kids. Starting with kids is a good way of teaching the message early in their lives, in the hope that they can carry it forward as they grow older.
With environmental protection awareness in mind, we can do what we can, for the results are to have a big effect on the planet. As long as we do our part, the world is one small step closer to being saved

The world's largest solar thermal plant(太阳热能发电站)is set to begin producing power in the United States by the end of the year. Wind and energy from the sun are generally considered clean, unlike energy from coal-burning power stations. However, environmentalists now worry that too much solar power development could harm the local environment.

A California company — BrightSource Energy is building a huge solar power plant in the Mojave desert, about 60 kilometers southwest of Las Vegas, Nevada. The plant is known as the Ivanpah Solar Electric Generating System. Joe Desmond works for the company. "This is actually one of the highest concentrations of sunlight in the world, out here in Ivanpah." explained Desmond. BrightSource Energy will deploy 170,000 specially de­signed mirrors to direct solar energy towards boilers on top of three power towers. The steam produced in the boilers will drive turbine (涡轮) to make electricity. Joe Desmond says the steam can reach temperatures of more than 260 degrees Celsius. "We can store the sun's thermal energy in the form of molten salt, so we can produce electricity even when the sun goes down. There is a lot of interest in concentrating solar power around the globe in environmnents where you have lots of sun, such as China, South Africa, the Mid­dle East, North Africa, explained Desmond.

Environmentalists generally support the idea of solar power, however, many are concerned about the effect of power plants on sensitive environment. Lisa Belenky is a lawyer with the Center for Biological Diversity, a private group. She says environmentalists are specifically worried about the effect of the Ivanpah Solar Project on the sensitive plant and animal life in that part of Mojave desert. "Even though the desert seems big, when you start cutting it up, it can really affect how the species and the animals and the plants are able to survive in the long run,"said Lisa Belenky. BrightSource Energy has already spent more than $ 50 million to move endangered desert tortoises away from the power plant. but Lisa Belenky says this is not the answer. "We should be reusing areas that have a1ready been disturbed, like old mining sites, for example...either on homes, on businesses, parking lots." said Belenky.

There have also been reports of birds dying at the Ivanpah Plant and others like it.

Some birds die after colliding with solar equipment which the animals mistake for water. Other birds were killed or suffered burns after flying through the intense heat at the solar thermal plant. As solar projects increase, environmentalists and developers are considering what to do to reduce bird death.

1.Why is the Ivanpah Solar Electric Generating System being built in the desert?

A. Because the temperature is extremely high in the desert.??

B. Because there is no life in the desert.

C. Because there is much salt in the desert.?????????????

D. Because sunlight is highly focused in the desert.

2.Why can the plant make electricity at night?

A. Because the sun's thermal energy can be stored in the form of steam.

B. Because the sun's thermal energy can be stored in the form of molten salt.

C. Because the sun'ss thermal energy can be stored through mirrors

D. Because the sun's thermal energy can be stored in the boilers.

3.According to Lisa Belenky, in order to reduce the effect,_____.

A. we should move all the plants and animals away from the solar plant

B. we should guide the bird not to hit the solar plant

C we should build the solar plant in disturbed areas

D. we should build the solar plant in the desert

4.The author’s attitude towards the solar projects is _____.

A. supportive????????????? B. critical????????????? ??? ??????? C. indifferent????????????? ?????????? D. cautious

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover,these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns,potentially causing certain natural disasters all over the world.

In the past hundred years,humans have begun destroying rainforests in search of three major resources(资源):land for crops,wood for paper and other products,land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.There are two main reasons for this. Firstly,when people cut down trees,generally they can only use the land for a year or two. Secondly,cutting large sections of rainforests may provide a good supply of wood right now,but in the long run it actually reduces the world’s wood supply.

Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However,fewer than l%of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.

Rainforests can help to adjust the climate because they      

A. reflect more heat into the atmosphere

B. bring about high rainfall throughout the world

C. rarely cause the temperature to drop lower than l6℃

D. reduce the effect of heat from the sun on the earth

What does the word “this” underlined in the third paragraph refer to?

A. We will lose much more than we can gain.

B. Humans have begun destroying rainforests.

C. People have a strong desire for resources.

D. Much carbon dioxide comes from burning rainforests.

It can be inferred from the text that

A. we can get enough resources without rainforests

B. there is great medicine potential in rainforests

C. we will grow fewer kinds of crops in the gained land

D. the level of annual rainfall affects wind patterns

What might be the best title for the text?

A. How to Save Rainforests

B. How to Protect Nature

C. Rainforests and the Environment

D. Rainforests and Medical Development
