ALTERNATIVE ENERGY SOURCES
Fossil fuels are the cause of many problems. They create terrible pollution which leads to global warming. Many wars are fought to control oil and gas fields. Fossil fuels are also nonrenewable resources. They will be exhausted someday. Societies around the world suffer when fuel shortages occur.
Can solar power completely replace fossil fuels? Solar power is clean, safe, and inexpensive. But the idea of replacing fossil fuels with solar power alone is totally unrealistic. Current solar cell technology is not advanced enough. Solar cells are not dependable. They are useless in cloudy and rainy weather as well as at night. Also, they take up too much space. Then they fail to produce sufficient amounts of power.
The soft energy path is a good alternative to fossil fuel reliance. The soft energy path is an energy conservation plan. It is an alternative to the hard energy path. Hard energy is defined as harmful and nonrenewable. Fossil fuels and nuclear power are included. On the other hand, soft energy is defined as renewable and environmentally safe energy. Solar and wind power are soft energy. Biofuel and geothermal energy are also included.
There are many proponents of the soft energy path. They believe the solution lies in new energy production methods. The first step is to practice careful conservation in our use of hard energy technologies. Then, many new soft energy sources will be phased into use as soft energy technology improves.
Some critics claim this will damage all energy production. They feel fossil fuels are important. They want to control as much oil production as possible. They think fossil fuel consumption is good for industry.
Countries such as Canada and Sweden are taking the soft energy path. Canada is currently lessening its reliance on gasoline. In the next few years, all gasoline will contain a percentage of biofuel. Sweden has committed to decrease its reliance on oil by 40%. It says it can do this before the year 2020.
51. According to the passage, which of the following is true about the soft energy path?
A. It is an energy conservation plan.
B. It is harmful and nonrenewable fuel.
C. It is useless in cloudy and rainy weather.
D. It is biofuel and geothermal energy.
52. According to paragraph 6, all of the following are true EXCEPT:
A. The soft energy path has been adopted by Canada and Sweden.
B. Canada is trying to use less gasoline every year.
C. All gasoline in Canada will contain some biofuel in a few years.
D. Sweden will cut down on the consumption of oil by 90% in the future.
53. The word exhausted in the passage is closest in meaning to
A. wasted
B. used up
C. worn out
D. burned
54. In stating that many soft energy sources will be phased into use, the author means that they will
A. be an alternative to the hard energy path
B. be used gradually
C. be adopted by Sweden and Canada
D. damage all energy production

Almost all our energy comes from oil, coal, and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What will happen when there is no oil, coal and gas on the earth? Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, the wind, and the water. Solar energy is unlimited. The sun supplies all the energy used to grow plants, to evaporate water for the rain, and to maintain the temperature of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source of power.
66.What are the other words or phrase for fossil fuels?
A. oil B. oil, gas, natural gas C. natural gas D. coal
67.Natural sources of energy are energy from .
A. the sun, wind, water B. water C. wind D. the sun
68.From which do plants on the earth get energy?
A. the moon B. the sun C. stars D. the Mars
69.We are asking the question, “What will happen when there is no oil, coal, and gas on the earth?” because .
A. we are looking for other alternative sources of energy B. we are looking forward to seeing great changes
C. we are now depending so much on oil, coal, and natural gas
D. other sources of energy can come from the sun, wind, and water
70.The word “abundant” in the passage is closest in meaning with .
A. natural B. necessary C. plentiful D. Limited

KEEPING OUR TEETH HEALTHY
How can we keep our teeth healthy? First, we ought to visit our dentist twice a year. He can fill the small holes in our teeth before they destroy the teeth. He can examine our teeth to check that they are growing in the right way. Unfortunately, many people wait until they have toothache before they see a dentist.
Secondly, we should brush our teeth with a toothbrush fluoride toothpaste at least twice a day – once after breakfast and once before we go to bed. We can also use wooden toothpicks to clean between our teeth after a meal.
Thirdly, we should eat food that is good for our teeth and our body: milk, cheese, fish, brown bread, potatoes, red rice, raw vegetables and fresh fruit. Chocolate, sweets, biscuits and cakes are bad, especially when we eat them between meals. They are harmful because they stick to our teeth and cause decay.
People are advised to eat chocolate, sweets biscuits and cakes between meals
