In manycountries, cellphones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected. The explosion in mobile phone use around the world has made some health professionals worried. Some doctors areconcerned that in the future many people may suffer health problems from the use of mobile phones. In England, there hasbeen a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones.Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, atraveling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks.He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day, everyday of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctordidn't agree. What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect verysmall amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they saythe amount is too small to worry about. As the discussion about their safety continues, it appears that it's best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones canbe very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that saysthey are bad for your health. So for now, it's wise not to use your mobile phone too often. 1. According to the passage, cellphones are especially popular with young people because . A. they make them look more stylish B. they keep the users alert all the time C. they cannot be replaced by regular phones D. they are indispensable in everyday communications 2.

A. their radiant light B. their raiding power C. their power of attraction D. their invisible rays READING PASSAGE 2 In the future, maybe all cars that run on petrol will be replaced by solar cars, which have been around for a while, but with recent developments in solar car design and the measurement of photovoltaic cells becoming smaller, the dream of a truly efficient solar car is more reality than fantasy. A solar car is a vehicle powered by photovoltaic cells, also called solar cells, which convert sunlight (light energy) into electrical energy. As a source of energy on earth, there is nothing like the sun: in a mere one thousandth of one second (.001), it emits enough energy to fulfill our planet's energy needs for the next 5,000 years. It is a staggering fact, and an exciting one. Since the energy from the sun is responsible for renewable resources such as wind, tides, and heat, solar energy seems to offer the brightest future for not only cars, but for the entire energy crisis. Despite the
8. appearance that solar energy may be the least feasible among the current crop of alternative fuel propositions, new solar powered devices and more specifically solar powered cars are beginning to be developed. How do Solar Cars work? The photo-voltaic cells absorb photons from sunlight. This action generates heat, which the cells then convert into electrical energy and stores in an on-board battery. This process of conversion is called the photovoltaic effect. Not surprisingly, such a vehicle has zero emissions, and is very environmentally friendly. Unfortunately, at the moment photovoltaic cells are extremely inefficient, yet as time progresses the efficiency of these cells willgrow. This will make solar energy and solar cars the fuel and car of the future-a closer reality. 1. According to the text, ___. A. up to now, we have designed some solar cars B. solar cars have been very popular for many years C. we have not produced any solar cars yet D. solar cars have already replaced gasoline cars 2. What does the word “it” in line 5 refer to? A. solar car B. electrical energy C. sunlight D. the sun 3. A solar car is supplied power from ___. A. gas B. petrol C. photovoltaic cells D. electricity 4. Which can not help us to solve the problem of energy crisis? A. wind B. tide C. the sun D. heat from the moon 5. According to the text, ___ A. no powered solar devices have been developed so far B. besides solar car, we have also developed solar powered device C. solar energy plans are more feasible than wind energy plans D. tide can supply more energy than the sun 6. What can best replace the word “convert” in line 10? A. make B. force C. form D. change 7. The photovoltaic effect is ___. A. the process of operating a solar car B. the process of absorbing photons from the sun C. the developing of solar cars and devices D. the converting of heat from the sun into electricity READING PASSAGE 3 Carbohydrates, which are sugars, are essential part of healthy diet. They provide the main source of energy for the body, and they also function to flavor and sweeten foods. Carbohydrates range from simple sugars like glucose to complex sugars such as amylose and amylopectin. Nutritionists estimate that carbohydrates should make up about one-fourth to one-fifth of a person’s diet. This translates to about 75-100 grams of carbohydrates per day. A diet that is deficient in carbohydrates can have an adverse effect on a person’s health. When the body lacks a sufficient amount of carbohydrates it must then use its protein supplies for energy, a process called gluconeogenesis. This, however, results in a lack of necessary protein, and further health difficulties may occur. A lack of carbohydrates can also lead to ketosis, a build-up of ketones in the body that causes fatigue, lethargy, and bad breath. 1. What is the main idea of this passage? A. Carbohydrates are needed for good health. B. Carbohydrates prevent a build-up of proteins. C. Carbohydrates can lead to ketosis D. Carbohydrates are an expendable part of good diet. 2. The word “function” as used in line 2 refers to which of the following? A. neglect B. serve C. dissolve D. profess 3. The word “range” as used in line 2 is closest in meaning to which of the following? A. probe B. proceed C. hail D. extend 4. According to the passage, what do most nutritionists suggest? A. Sufficient carbohydrates will prevent gluconeogenesis. B. Carbohydrates are simple sugars called glucose. C. Carbohydrates should make up about a quarter of a person’s daily diet. D. Carbohydrates should be eaten in very small quantities 5. Which of the following do carbonhydrates NOT do? A. prevent ketosis B. cause gluconeogenesis C. provide energy for the body D. flavor and sweeten food 6. What does the word “this” in line 7 refer to? A. using protein supplies for energy B. converting carbohydrates to energy C. having a deficiency in carbohydrates D. having an insufficient amount of protein 7. According to the passage, which of the following does NOT describe carbohydrates? A. a protein supply B. a necessity C. a range of sugars D. an energy source READING PASSAGE 4 A pilot cannot fly by sight alone. In many conditions, such as flying at night and landing in dense fog, a pilot must
9. use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving. The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300,000 kilometers in one second. A radar set sends out a short burst of radio waves. Then it receives the echoes produced when the waves bounce off objects. By determining the time it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects. The word “radar”, in fact, gets its name from the term “radio detection and ranging”. “Ranging” is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots, radar is essential for air traffic control, tracking ships at sea, and for tracking weather systems and storms. 1.
