It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things. First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it. Second, we need to watch the amount of water used in the home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth. Third, we need to reduce waste. We need to recycle whenever possible, but should also try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing. If we do our part in our own homes, we can help keep the planet from becoming more polluted. 24 How many ways of saving the environment are mentioned in the passage? A. one B. two C. three D. four 25. The word “It” in paragraph 2 refers to A. the number B. recycling C. effort D. paper 26. In order to save water, we can do the following things EXCEPT A. take short showers B. repair leaky faucets C. turn the faucet off while brushing your teeth D. fully use the washing machine 27. Which of the following statements are TRUE according to the passage? A. We can only see environment throughout the world B. We can reduce waste by means of recycling and reusing C. Recycling takes great effort D. It is hard to place plastic and glass bottles 28 What is the topic of the passage? A. Saving the environment in homes B. Causes of environment pollution C. Effects of environment pollution D. Solving the broblem of recycling Đọc 3 Most of the people who like films are only interested in the leading actor or actress when they enjoy a film. It seems to them that only the actors or actresses have made the film successful. They always pay attention to their appearance, performance, and fashion. There are many film viewers who have no awareness of the other people’s work to make a film. A finished film is, actually, the result of the collaboration of many people, and the most important among them are the scriptwriter, the cinematographer, the film editor, the actor, and the director. Especially, in some thrilling scenes, the roles of stuntmen are very important. They are always in danger when they are acting; some of them are even badly hurt. But what a pity, many film viewers rarely appreciate their work. 29 Who are many film viewers most interested in? A. The director. B. The leading actor or actress. C. The stuntmen. D. The cinemaphotographer. 30. According to the passage, only the actors or actresses have made . A. best scenes B. bad scenes C. they love films D. the film successful

Read the passage and choose the correct answer (A, B, C, or D)

The search for alternative sources of energy has led in various directions. Many communities are burning garbage and other biological waste products to produce electricity. Converting waste products to gases or oil is also an efficient way to dispose of waste.

Experimental work is being done to derive synthetic fuels from coal, oil shale and coal tars. But to date, that process has proven expensive. Other experiments are underway to harness - power with giant windmills. Geothermal power, heat from the earth, is also being tested.

Some experts expect utility companies to revive hydroelectric power derived from streams and rivers. Fifty years 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 source of energy. Scientists are studying ways to convert the energy of ocean currents, tides, and waves to electricity. Experiments are also underway to make use of the temperature differences in ocean water to produce energy.
