City traffic is a great problem. More cars are produced every year and the streets are getting more and more crowded. So during "rush hours", when people are going to or from their work, traffic is brought to a standstill. It has been suggested that commuters--the people who travel to work every day from outside the city--should share their cars and give each other lifts. So each car would carry four or five people instead of only one. It is an excellent idea., however, so far nobody has been able to think of a way to make people do so. To discourage motorists from leaving their cars in the streets all day, parking meters are used. When you park at a meter, you must put a coin in the slot . This pays for a certain amount of time. The meter records this and it shows when the time that you have paid for is finished. If the car is still there then, you have to pay a fine. Traffic wardens look after the meters. They walk around the streets and check that every meter shows that money has been paid for the car parked there. If a meter shows 'TIME EXPIRED', the motorist who has left his car there is fined. Of course, the traffic warden can not wait for the owner of the car to return. He carries many printed forms, and on one of these he writes down all the details, such as the number of the car, where it is parked, how much the driver must pay and where he must send the money. He leaves this form on the car, where the driver will be able to see it easily; he usually pushes it under one of the windscreen wipers so that it will not be blown away. And in case it rains before the motorist returns, the form is put in a little plastic envelope to protect it. When the driver comes back, he gets an unpleasant surprise, but it is his own fault for leaving his car too long at parking meter. The suggestion that commuters should share their cars is_. A) impossible to be accepted B) difficult to be put into practice C) liked by nobody D) not yet necessary to be put into practice

Batteries are included, but the charger's not. The Nokia E-Cu concept phone doesn't need to plug in, it charges from any heat source. Designer Patrick Hyland says it can even work off the warmth of your pocket. The first time "it would take approximately seven hours to reach full charge, then after that it's continuously charging by keeping the phone in areas between 86 degrees and 104 degrees Fahrenheit." That's one hot pocket.? He's put a thermogenerator inside the phone that transforms heat into electric potential energy. To better conduct the heat to that little power plant in your pocket, the E-Cu (E for energy, Cu for copper) is coated by copper backing with heat sinks like those normally used to keep electronics from overheating. Nokia doesn't have current plans to build the phone, so for now it remains a concept. But Hyland says he's open to anyone who wants to cooperate. For Americans this technology would certainly be convenient. It would also save a bit on energy bills and waste. "Annually, unwanted phone chargers produce 51,000 tons of waste in addition to the greenhouse gases created by the production of the electricity needed to charge them," Hyland says. So a charger-free phone is also a green phone. Though adapting our plug in habits would help a group of people, most cell phone related energy use comes from leaving your charger plugged in all day unnecessarily. The real potential for charger-free cell phone technology is what it could enable places where plugging in isn't an option, like rural areas in the developing world. Cell phones are spreading faster than power lines and bringing with them countless opportunities, aid and health advances. A phone like the E-Cu, if it ever comes to be, would enable all manner of expanded aid and development by phone projects. Let's hope Patrick finds a partner. What is the best title of the text? A) Designer Patrick Hyland B) Nokia Concept Phone on Sale C) Charging Your Phone from Pockets D) Benefiting from Phone Technology

Q: A newspaper, a publication usually issued on a daily or weekly basis, has the main function of reporting news. Many newspapers also _ their readers with other pieces of useful information, such as weather reports, television schedules, and stock prices. They provide commentary on politics, economics, and arts and culture. In nearly all cases and in varying degrees, newspapers depend on commercial advertising for their income. Newspaper publishers estimate that nearly six out of ten adults in the United States and Canada read a newspaper every day, and seven out of ten read a paper each weekend. By the time they see a newspaper; most people have already heard about breaking news stories on television or on the radio. Readers rely on newspapers to provide detailed background information and analysis which television and radio rarely offer. Newspapers not only inform readers that an event has happened but also help readers understand what led to the event and how it will affect the world. The staff of a large newspaper works under the constant pressure of deadlines to bring news to readers as quickly as their minds, bodies and the technology they use permit. Reporters, photographers, artists, and editors compile articles and graphics -- sometimes in just a few hours. Page designers combine articles, photos, advertisements, and eye-catching headlines into page layouts , then rush their work to the printer. Printing technicians may work through the night operating printing presses that can print out more than 60,000 copies per hour. According to the passage, what affects the pace of a newspaper's publication? A) The editors. B) The printers. C) The newspapers' human resources and technology. D) The reporters.

Q: In recent years, there has been a steady attack on salt from the doctors: salt is bad for you--regardless of your health. Politicians also got aboard. "There is a direct relationship," US Congressman Neal Smith said, "between the amount of sodium a person consumes and heart disease, circulatory disorders, stroke and even early death." Frightening, if true! But many doctors and medical researchers are now beginning to feel the salt scare has gone too far. "All these remarks and cry about salt is unnecessary," Dr. Dustan insists. "For most of us it probably does not make much difference how much salt we eat." Dustan's most recent short-term study of 150 people showed that those with normal blood pressure experienced no change at all when placed on an extremely low-salt diet, or later when salt was reintroduced. Of the hypertensive patients, however, half of those on the low-salt diet did experience a drop in blood pressure, which returned to previous level when salt was reintroduced. "An adequate to somewhat excessive salt intake has probably saved many more lives than it has cost in the general population," said Dr. John H Laragh. "So an opinion that the whole population should avoid salt makes no sense." Medical experts agree that everyone should practice reasonable "moderation" in salt consumption. For the average person, a moderate amount might run from four to ten grams a day, or roughly 1/2 to 1/3 teaspoons. One to two grams of salt would come from the natural sodium in food. The rest would be added in processing, preparation or at the table. "Na is not your enemy," says Comek's Dr. Laragh. "Salt is the No.1 natural component of all human tissue, and the idea that you do not need it is wrong. Unless your doctor has proven that you have a salt-related health problem, there is no reason to give it up." Why is salt attacked by doctors and politicians? A) It's unnecessary. B) It does no good to human health. C) It is hated by most people. D) It will always lead to heart disease and circulatory disorders.
