So it might be difficult to imagine anything twice as big. All together, this mass of waste flowing in the North Pacific Ocean is known as the Great Pacific Ocean Garbage Patch. It weighs about 3 500 000 tons. The waste includes bags,bottles and containers--plastic products of all kinds.www.zxxk.com The eastern part of the Great Pacific Ocean Garbage Patch is about l 600 kilometers west of California. The western part is west of the Hawaiian Islands and east of Japan. The area has been described as a kind of oceanic desert,with light winds and slow moving water currents. The water moves so slowly that garbage from all over the world collects there. In recent years,there have been growing concerns about the floating garbage and its effect on sea creatures and human health. Scientists say thousands of animals get trapped in the floating waste,resulting in death or injury. Even more die from a lack of food or water after swallowing pieces of plastic. The trash can also make animals feel full,lessening their desire to eat or drink. The floating garbage also can have harmful effects on people. There is an increased threat of infection of disease from polluted waste,and from eating fish that swallowed waste. Divers can also get trapped in the plastic.www.zxxk.com Its existence first gained public attention in l997. That was when racing boat captain and oceanographer Charles Moore and his crew sailed into the garbage while returning from a racing event. Five years earlier,another oceanographer learned of the trash after a shipment of rubber duckies got lost at sea. Many of those toys are now part of the Great Pacific Ocean Garbage Patch. In August,2009,a team from the University of California,San Diego became the latest group to travel to it. They were shocked by the amount of waste they saw. They gathered hundreds of sea creatures and water samples to measure the garbage... Question: Why do people pay attention to the Great Pacific Ocean Garbage Patch?

Q: Read the article and select the best answer. Article: Solar water heaters can use energy from the sun to heat water. They are used around the world. The solar water heater is based on a design developed some years ago in Afghanistan. Since then, it has been built and used in many countries. It can heat seventy liters of water to 60degC. It can do this between sunrise and noon on a clear day with an average temperature of 32degC. There are two parts of the solar water heater. One part, the collector, is made of a metal plate painted black. This metal surface, placed in contact with the water, will heat the water. Black-painted surfaces that receive the sun's heat become hotter than those of any other color1. Metal plates that have raised parts on the surface work better than those without them. Once the water is heated, it is kept hot with special material, which allows the water to stay warm for a long time. The second part of the solar water heater holds the water for the system. This water tank can hold about one hundred liters of water. Two rubber pipes are connected to the water tank. One pipe lets water go into the system. The other lets water go out. When the water heater is working correctly, water will flow from the tank to the collector and back again. You can use the hot water at the top of the tank for washing and cleaning. This solar water heater is easy to build and operate. It will last about two years before the rubber pipes need to be replaced. Question: The color1 of the collector is black because _ . Options: A: it is the cheapest color1 paint B: it can be found easily in daily life C: it can take in more energy than other color1s D: it is good for protecting the metal surface
A: C

Read the article and select the best answer. Article: They like using the Internet. They have lots of pocket money to spend. And they spend a higher proportion of it online than the rest of us. Teenagers are just the sort of people an online seller is interested in, and the things they want to buy-games, CDs and clothing-are easily sold on the Web. But paying online is a tricky business for consumers who are too young to own credit cards. Most have to use a parent's card. They want a facility that allows them to spend money. That may come sooner than they think: new ways to take pocket money into cyber space are coming out rapidly on both sides of the Atlantic. If successful, these products can stimulate online sales. In general, teenagers spend huge amounts: $153bn (billion) in the US last year and PS20bn annually in the UK. Most teenagers have access to the Internet at home or at school-88 percent in the US, 69 percent in the UK. According to the Jupiter Research, one in eight of those with Internet access has bought something online-mainly CDs and books. In most cases, parents pay for these purchases with credit cards, an arrangement that is often unsatisfactory for them and their children. Pressing parents to spend online is less productive than pressing on the high street. They are more likely to ask "Why?" if you ask to spend some money online. One way to help teenagers change notes and coins into cybercash is through prepaid cards such as InternetCash in the US and Smart cards in the UK. Similar to those for pay-as-you-go mobile telephones, they are sold in amounts such asPS20 or $50 with a concealed 14-digit number that can be used to load the cash into an online account. Question: According to the passage, which of the following statements is TRUE? Options: A: More than half of the teenagers in the US and the UK have Internet access. B: Teenagers pay for goods online with their own credit cards. C: Most teenagers in the US and the UK have bought something online. D: Teenagers found it easier to persuade parents to buy online than in a shop.
