Read the following passage and choose the correct answer. 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. 1. Which is the best title of the passage? A. Efficient Ways of Disposing of Waste B. The Use of Water Productions for Energy C. The Search for Alternative Sources of Energy D. New Discoveries in Geothermal Power 2. In the second paragraph, the phrase “synthetic fuels” could best be replaced by which of the following? A. Biological fuels B. Low burning fuels C. Fast burning fuels D. Artificial made fuels 3. Which of the following is NOT mentioned in the passage as an alternative source of energy? A. Burning of garbage B. Geothermal power C. Synthetic fuels D. Electricity 4. According to the author, the impracticability of using coal, oil shale and coal tars as sources of energy is due to ___________ . A. their being time consuming B. their being money consuming C. the scarcity of sources D. the lack of technology their being money consuming 5. The word “it” in the last paragrph refers to ____. A. alternative source B. the United States C. hydroelectric power D. Electricity 6. What can be inferred from the last paragraph? A. Hydroelectric power will be the main source of energy B. Synthetic fuels will be the principal source of alternative energy C. Alternative energy will come from a variety of sources D. All alterenative production of energy will be delivered from water.

Using a microwave for cooking a large food mass is difficult due to limited penetration of microwaves. B. This can be overcome by leaving the food to stand for a few minutes when cooking is completed. C. It is advised that the water should be poured slowly into another container that already contains the powder. D. In this way, buying a microwave oven with a turntable ensure the food is cooked throughout. E. Conversely the microwaves do not heat glass, ceramic and plastic containers. F. If the microwaves are not absorbed inside the oven, the oven can be damaged by electrical arcs and overheating of the microwave source. G. When water in that state is disturbed, it can suddenly and unexpectedly boil violently. MICROWAVING Microwaving is a method of cooking where food is bombarded by microwaves, usually within an appliance called a microwave oven which excite the water, fat and sugar molecules, thereby heating (cooking) both the outside and center of the food at the same time. (1) (A common myth is that a microwave oven cooks from the center of the food outward. This appears to happen because heat generated at the surface escapes more readily from the surface of the food into the surrounding air.) One advantage of microwaving is that small amounts of food can be heated very quickly, making it useful for reheating leftovers. The disadvantage is that food which is microwaved does not undergo some of the chemical reactions, such as browning, which makes the food visually attractive. Primitive microwave ovens often do not cook evenly, leading to a concern that bacteria easily killed by more traditional cooking methods may survive the quick cooking time in "cold spots", though the food item as a whole is cooked to a safe average temperature. (2) Some high-end microwave ovens are combined with a convection oven which basically cook the food using microwave and hot air simultaneously to achieve both the fast cooking time and browning effect. (3) However microwave ovens are used in some fast food chains and special microwave bags are available for cooking fowl or large joints of meat. Professional chefs generally recommend using microwaves for a limited set of tasks, including: melting fats (such as butter) and chocolate, cooking grains like oatmeal and grits, cooking rice, thawing frozen meats and vegetables before cooking by other methods and quickly reheating already-cooked foods. Using a microwave to boil water is potentially dangerous, due to superheating. In a microwave, water can be raised quickly to a temperature above the boiling point before major bubbles form, especially if it is purified and in a very clean glass vessel. (4) This effect is rare, even for scientists who try to deliberately recreate it, and any seed whatsoever for boiling is likely to prevent the problem. Boiling water with, for instance, a teabag already in it will prevent any dangers by providing a seed, as will using a mug that is not perfectly clean. The risk greatly increases when water has already been boiled once in the same container. This situation can occur if the user of the oven boiled the water once, forgot about it, then came back later to boil it again. The first time the water boils, the seed bubbles (microscopic bubbles of air around which larger steam bubbles grow) are used up and largely eliminated from the water as it cools down. When the water is heated again, the lack of seed bubbles causes superheating, and a risk of a steam explosion when the water's surface is disturbed. Placing something in the water before heating can mostly alleviate this risk. If you are planning to mix something with the water, say tea or hot chocolate, adding it before heating will insure that the water boils. Otherwise, placing a wood object, for instance a chopstick, in the water before heating will also work. Care should be taken when removing heated water from a microwave. Make sure that the hands are protected from possible liquid boil-over, place the container on a level, heat-proof surface and stir liquid with a warm spoon. Also, never add powdered substances (such as instant coffee or cocoa mix) to the container taken from the microwave, due to the addition of all those seed bubbles and the potential for violent, spontaneous boiling. (5) Metal objects, such as metal utensils, in a microwave oven can lead to dangerous situations. Metals do not absorb microwaves effectively. Instead, metals reflect microwaves, thereby preventing the latter from reaching the food. (6) Thin metal layers, such as metal foil and mugs with metal trim can melt or burn due to the strong electrical currents that are generated in metal objects. However, small solid metal objects, such as spoons, in combination with a large amount of absorbing food or liquid, normally do not lead to problems.

III) Read the following passage and choose the best answer: (2ms) Computing is now at the same stage as printing was when the first printing presses were used. Before printing presses were invented, only rich people like kings and dukes could afford to buy books. Often these people were unable to read and hadn’t enough time to learn. In any case, the books were so big that it was difficult for anyone to relax with a book as we do today. They wanted booked because they were expensive and there was something magical about them. Only a few people were able to write, and it took an extremely long time to write a book. Monks and other people who could write said ordinary people could not learn to read. The position with computers is very similar today. A few years ago, computers were very large and expensive. Business managers and rich people ordered them but they didn’t know how to use them. In many countries, however, the situation has now completely changed. Lots of people not only own microcomputer but also know how to use them. 10 đề thi vào 6 Tiếng Anh Trần Đại Nghĩa(tặng); Bộ 35 đề đáp án vào 6 Anh 2019-2020=40k; BỘ 30 ĐỀ-ĐA ANH VÀO 10 CÁC TỈNH 2019-2020=40k; BỘ 9 ĐỀ-ĐA CHUYÊN ANH VÀO 10 CÁC TỈNH 2019-2020=20k.
