The oldest and most common source of renewable energy known to man, biomass(生物质) is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of biomass materials is everywhere —- from trees and grasses to agricultural and city —- life wastes —-biomass promises to play a continuing role in providing power and heat for millions of people around the world.
According to the Union of Concerned Scientists(UCS), biomass is a kind of renewable energy source that produces no carbon dioxide(二氧化碳), because the energy it contains comes from the sun. When plant matter is burned, it gives off the sun’s energy. In this way, biomass serves as a sort of natural battery(电池) for storing the sun’s energy. As long as biomass is produced continuously —-with only as much grown as is used— the “battery” lasts forever.
According to the Energy Information Administration, biomass has been one of the leading renewable energy sources in the United States for several years running through 2007, making up between 0.5 and 0.9 percent of the nation’s total electricity supply. In 2008—-although the numbers aren’t all in yet—-wind power probably took over first place because of the rapid development of wind farms across the country.
Producing power from biomass helps reduce some 11 million tons of carbon dioxide each year. Some homeowners also try to make their own heat by using biomass materials. Such practice may save homeowner’s money, but it also produces a lot of pollution. So, the best way is to encourage power plants to use it.
1. Why is biomass considered as “ a sort of natural battery”?
A. It burns merely plant matter.
B. It keeps producing electricity.
C. It stores the energy from the sun.
D. It produces zero carbon dioxide
2. We learn from the text that in 2008 ______.
A. Wind power would be the leader of renewable energy.
B. there was a rapid growth of electricity production
C. biomass might become the main energy source
D. 0.5~0.9 of power supply came from biomass
3. Why does the author encourage power plants to use biomass?
A. To prevent the waste of energy.
B. To increase production safety.
C. To reduce pollution.
D. To save money.
4. Where does the text probably come from?
A. A research plan. B. A science magazine
C. A book review. D. A business report.

You have most likely heard of renewable energy or even used it in your home, or office to do your part for the environment. Renewable energy is energy from natural resources including the wind, sunlight, and water. This form of energy is always renewed and cannot be exhausted. The most popular modern day form of this energy can be seen in solar paneling(电池板). Renewable energy can produce electricity and plays a major role in reducing greenhouse emissions(排放) and fossil fuels (化石燃料).
A study by the Department of Energy’s National Renewable Energy Laboratory predicts that renewable energy resources can soon provide up to 80 percent of the electricity in the United States. The study was conducted to decide how renewable energy can meet the needs of a rapidly increasing population. Using the current solar panels, wind turbines, geothermal(地热), and hydropower, this 80 percent increase is a promising possibility for our future.
Increasing this renewable energy will provide practical benefits for our economy, climate, and health. Not only will it greatly reduce global warming, but it will improve public health, and provide many economic benefits. In a future with 80 percent fewer renewables, our carbon emissions will also be reduced by 80 percent, and water use will be cut in half.
This future is both possible and affordable, and we already have the tools in place to begin. However, we need to make improvements to our current electricity grid(电网) first. Additionally, the United States needs to carry out a clean energy policy for renewables.
1.The passage is mainly about _______.
A. protecting the environment
B. the use of renewable energy
C. reducing global warming
D. the form of renewable energy
2.What is the closest meaning to the underlined word “exhausted” in the first paragraph?
A. Tired. B. Removed.
C. Created. D. Used up.
3.Which of the following is not renewable energy?
A. Solar. B. Geothermal.
C. Hydropower. D. Fossil fuels.
4.What will the renewables bring us?
A. Doing good to our economy, climate, and health.
B. Partly increasing global warming.
C. Increasing our cost.
D. Improving current electricity grid.

The pomegranate is one of the oldest known fruits. Pomegranates are found in ancient writings and pictured in the ancient art of many cultures and religions. The pomegranate is also a symbol of health, fertility and long life.
Experts think the pomegranate is native to northern India, Pakistan, Iran and Afghanistan. Today it also grows in Southeast Asia, the western U.S., Armenia and parts of Africa, among other places.
The skin of a pomegranate is strong. It can be red, purple or orange-yellow. The inside is filled with beautiful dark red seeds that shine like rubies. It is not easy to get them out. But the reward is great.
Health benefits
The pomegranate grows on trees. Parts of the pomegranate tree and fruit are used to make medicine.
The pomegranate is used for many conditions. However, the U.S National Institutes of Health says there is not enough scientific evidence to rate pomegranates as effective for any of them.
Still, in traditional medicine, the pomegranate is used for conditions of the heart and blood vessels, including high blood pressure and "hardening of the arteries."
The jewel-like seeds of the pomegranate are loaded with many nutrients and chemicals called antioxidants(抗氧化剂). These antioxidants remove poisons from the body.
The antioxidants found in pomegranates may help remove build-up of damage in blood vessels. So, it is a very heart-healthy fruit.
Antioxidants slow the progression of age-related sickness and may slow the growth of cancer cells. Men who have prostate cancer may benefit from a daily serving of pomegranate juice.
Pomegranates are used for weight loss and used as a treatment for sore throat. Pomegranates are also high in vitamin K, phosphorus, magnesium, calcium, zinc and iron.
Let's just say pomegranates are loaded with great things for the inside of your body.
Beauty benefits
But let's not forget the outside, too!

Astronomy is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about the heavens. But man was limited by what he could see with his eyes alone.
The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.
Each new tool added to the field of astronomy helped man reach out into space. They did not know that the planet called Saturn(土星) had rings around it. Their sight was so limited that they could not see all the planets. In the early 1700s, people thought there were only six planets. Nepture(海王星), the last of eight planets to be discovered, was not seen until 1846.
Before the spectroscope(分光镜), man did not know what kind of gases was in the sun or other stars. Without the radio telescope, we didn’t know that radio noises came from far out in space.
Today, astronomy is a growing science. We had learned more in the last fifty years than in the whole history of astronomy.
1.. Thousands of years ago, people observed the stars with the limitation of their _____.
A. eyesight B. land

高一英语单项填空中等难度题查看答案及解析
There are three separate sources of danger in supplying energy by nuclear power (原子能)
First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas.
Second, there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes non-radioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.
Third, there may occur the danger of a leak(泄漏) or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.
Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster(灾难) is extremely high.
1.Which of the following is FALSE?
A. It is possible that a leak or an explosion occurs at a power station.
B. It is unusual for radioactive materials to be transported across land.
C. The containers are likely to be broken by an earthquake.
D. Nuclear wastes remain dangerous in most cases for many years.
2.The author thinks that the ways to store nuclear wastes are ___ .
A. easy B. impossible C. reasonable D. ineffective
3.What do we learn from the last paragraph?
A. The power station is a safe place.
B. The dangers of nuclear energy can be prevented.
C. The general public are strongly against the nuclear program.
D. By itself, none of the three dangers is very likely to cause much worry.
4.What is this passage about?
A. Uses of nuclear power.
B. Dangers from nuclear power.
C. Public anger at nuclear power.
D. Accidents caused by nuclear power.
5.As for the possible dangers of nuclear power, ______.
A. none of them can be completely avoided
B. effective measures have been taken to avoid them
C. man will never be able to do anything about them
D. one is usually the cause of another
