Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both nature and human life.
One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is. Because it can be simply removed and sent to a landfill（废渣填埋场）, the problem is often believed to end there. In addition, industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses. Many industries and governments build simple landfills to store waste, and often just pour waste chemicals into nearby bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste. The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment.
Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste.
Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce.
Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of dangerous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods.
72. What would be the best title for the text?
A. Measures of Reducing Dangerous Waste
B. Danger of Harmful Waste to Mankind
C. Dangerous Waste and Water Pollution
D. Environmental Protection
73. According to the text, people .
A. do not produce harmful waste in their daily life
B. do not know where to place the dangerous waste
C. are not clear about how serious the dangerous waste problem is
D. are not sure about where harmful waste ends
74. What troubles industries most in dealing with the dangerous waste problem?
A. How to get government support.
B. How to increase their production.
C. How to store harmful waste.
D. How to cut down the related costs.
75. What can be inferred from the passage?
A. The polluting industries are not allowed to sell their products.
B. Present technologies have settled the harmful waste problem.
C. Everyone should obey the government rules for the problem.
D. To solve the problem requires the efforts of the whole society.

Move Earth—it’s no science fiction
LONDON-Scientists have found an unusual way to prevent our planet from overheating: move it to a cooler spot. All you have to do is send a few comets（彗星）in the direction of Earth, and its orbit will be changed. Our world will then be sent spinning into a safer, colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration（NASA） engineers and American astronomers. They say their plan could add another six billion years to the useful lifetime of our planet—effectively doubling its working life.
The plan put forward by Dr Laughlin, and his colleagues Don Korycansky and Fred Adams
,needs carefully directing a comet or asteroid so that it passes close by our planet and sends some of its gravitational energy to Earth.
“Earth’s orbital speed would increase as a result and we would move to a higher orbit away from the Sun,”Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn. The comet would pick up energy from one of these giant planets. Later its orbit would bring it back to Earth, and the process would be repeated.
In the short term, the plan provides an ideal way to global warming, although the team was actually concerned with a much greater danger. The sun is certain to heat up in about a billion years and so “seriously compromise” our biosphere（生物圈）—by cooking us.
That’s why the group decided to try to save Earth.
The plan has one or two worrying aspects, however. For a start, space engineers would have to be very careful about how they directed their asteroid or comet towards Earth. The smallest miscalculation（误算）in orbit could fire it straight at Earth—with deadly consequences.
There is also the question of the Moon. As the current issue of Scientific American magazine points out, if Earth was pushed out of its current position it is “most likely the Moon would be stripped away from Earth,” it states. This would greatly change our planet’s climate.
1. What makes the scientists plan to move Earth?
A. A few comets are moving to the direction of Earth.
B. Earth’s working life is coming to an end soon.
C. Earth will become too hot for mankind to keep alive.
D. The moon is moving farther and farther away from Earth.
2.If the plan is successful, Earth will have a working life of ______years.
A.12 billion B.6 billion C.18 billion D.24 billion
3.What serious problems might the plan cause according to the passage?
A. The comet might hit Earth and man might lose the moon.
B. Earth might be moved too far away and man might be frozen to death.
C. The comet might hit Jupiter or Saturn and never return to Earth.
D. Earth’s working life might be greatly shortened.
4.What does the underlined word “compromise” mean?
A. provide B. benefit C. share D. endanger
5.Which of the following best shows how the plan would work?

If you dream of going someplace warm to escape the cold winter weather,a trip to a recently discovered planet would certainly warm you right up.The planet,named
OGLE-TR-56b,has temperatures of more than 3,000°F.“This is the hottest planet we know about,”says Dr Dimitar Sasselov,a scientist who led the discovery team.“It is hot enough to have an iron fog and to rain hot iron droplets(细沫).”
The new planet is 30 times farther away than any planet discovered by scientists
before.It is in the Milky Way(银河)but it is not in our solar(太阳的)system.The new planet moves around a star much like our sun,however scientists discovered the planet by using a new planetsearching method called transit technique.They were able to catch sight of the planet when it moved in front of its star,causing the star"s light to dim(变暗).Scientists compare the method to discovering the shadow of a bee flying in front of a searchlight 200 miles away.“We believe the door has been opened wide to go and discover planets like the Earth,”says Sasselov.
1.We can infer from the passage that_________.
A.there is iron on the new planet
B.we could go to the new planet in winter
C.the star could block our view of the new planet
D.scientists are studying the weather
2.The “transit technique”can_____________.
A.help dim the light of a star
B.help scientists with a searchlight

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 nonradioactive, 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.
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.
