Electric cars are better than petrol cars in several ways. The biggest benefit is reduced pollution. In areas where there is a high percentage of electric cars, there is less pollution. But it is important to understand that electric cars still cause pollution. Remember that the electricity to power electric cars has to come from somewhere, which is most likely a power station. Unless these power stations run on solar or wind energy, they are most likely burning fossil fuels to make electricity. The second benefit of electric cars is a reduction in the dependence on foreign oil. There are several countries, including the United States, that don’t want to rely on oil coming from other countries to power their transportation systems. They want the power to come from within their country, and since electric cars can run on electricity from coal or nuclear power stations, there is less of a need to import oil.
1. Electric cars aren’t better than petrol cars. F
2. Electric cars cause less pollution. T
3. People use electricity to power electric cars. T
4. In many countries, people don’t want to import oil more. T
5. Which is the best tittle for the passage?
A. Petrol cars B. Power C. Electric cars D. Benefit of electric cars
6. The word "rely on" in row 7 means __________.
A. base on B. go on C. keep on D. come on
The search (26) for alternative sources of energy has led in various directions. Many communi- ties are burning garbage (27) and other biological waste products to produce electricity. Converting waste products to gases or oil (28) is also an efficient way to dispose of waste.
Experimental work is being done to derive synthetic fuels (29) from coal, oil, shale and coal tars. However that process (30) has proved to be expensive. Other experiments that are underway to harness power with giant windmills are also (31) being tested.
Some experts expect utility companies to receive hydroelectric power (32) derived from streams and rivers. Fifty years (33) ago hydroelectric power provided one third of the electricity used in the United States, but today it supplies only four percent. The oceans are another potential sources of energy. Scientists are studying ways to convert the energy of ocean currents, tides and waves (34) to electricity. Experiments are also underway to make use (35) of temperature differences in ocean water to produce energy.
PART VII: (2.0 pts) Read the following passage and circle the answers A, B, C or D which is most accurate according to the information given in the passage.
In order to help solve the problem of pollution, people have to be aware of its causes, some of which are quite obvious in everyday life. In many cities people are forced to breathe in polluted air, commonly known as smog, which is a mixture of gases sent out by car exhausts and factory chimneys. What can be done to reduce air pollution is to remove factories from cities and use lead-free petrol in cars.
The pollution of rivers, lakes and seas leads to the death of the creatures that live in them. Factories are largely responsible for the present situation, which is expected to worsen if governments do not make them to obey the law against pollution and punish industries which pollute water.
Finally, all over the world, especially in cities, we see huge amounts of rubbish in the streets, which we are responsible for. The rubbish collection system often does not work properly and people themselves add to the problem by dropping litter in the streets. There is so much we could do to help solve the problem. The point is how willing are we to do something about it?
1. In order to help solve the problem of pollution,
A people need to know what causes it.
B people don’t need to know what causes it.
C people have to do something immediately.
D people don’t need to do anything about it.
2. Smog is caused by
A cars only
B factories only.
C cars and factories.
D air
3. The pollution of rivers, lakes and seas is largely caused by
A car exhausts.
B lead-free petrol in cars.
C factories.
D creatures.
4. Which of the following is NOT true?
A People add to the problem of pollution by collecting rubbish.
B People add to the problem of pollution by dropping litter.
C Huge amounts of rubbish in the cities cause pollution.
D We are responsible for huge amounts of rubbish in the cities.
5. The opposite of the word properly in the passage is
A unproperly B disproperly
C improperly D inproperly
