The Brooklyn Bridge was the first suspension bridge to link Brooklyn to Manhanttan.It is also the second oldest bridge in New York.The architect was John Augustus Roebling,who was the chief engineer of the suspended Railroad Bridge at Niagara Falls. Misfortune accompanied the building of the bridge,which took place from 1869 to 1883.The architect died as a result of an accident early during the construction.His son,Washington Roebling,carried on his father's work,using the most advanced engineering techniques of the day.He also fell ill during the construction of the bridge and was obliged to direct the work on it from an apartment window overlooking the site. Since its construction the Brooklyn Bridge has remained a busy and important passage in New York. The Brooklyn Bridge is 6775 feet long and 1595 feet wide.The suspended part is 3450 feet long and 85 feet wide.It has a clearance of 133 feet above water level.Four huge cables extend across the bridge,supported by two towers,each 272 feet high.Each of these cables is made up of 5700 wires. Question: The Brooklyn Bridge is _ . Options: A: the first suspended railway bridge in the USA B: the first oldest bridge in New York C: the first suspension bridge between Manhattan Island and Brooklyn D: the first suspension bridge built in the USA

Q: Read the article and select the best answer. Article: When someone says "SHARK" most people think of a big, toothy, underwater animal; basically we are imagining a Great White. In fact sharks come in all shapes, sizes and even colors! Follow me please; I'd like to show you a very special small shark commonly known as horn sharks, only found in the coastal waters of north-west North America. Look at this shark, and you can easily see the horns on it and you will know the reason why it is called the horn shark is that it has the broad, flattened head and two large horn-like spines found behind its eyes and makes it one of the hardiest of all shark species. What makes it unique is that as its enemy attempts to swallow it, the spines on its back will stick into the enemy's mouth and give a good chance for it to get away. The horn shark is brown in color with black spots all over its body. The adults can reach up to a length of 4 feet and weigh up to 10 kg. An interesting fact about the horn shark is that it has five gills . The horn shark is a clumsy swimmer using its flexible pectoral fins to push itself along the bottom of the ocean. The maximum distance that has ever been recorded for a horn shark to have traveled out from its habitat is 10 miles. Today, as so little is known about its population off the Californian coast, they have been listed as being "Data Deficient" in the World Conservation Union. The horn shark is being threatened both by water pollution and commercial fishing in the area. Though they are not among those sea creatures hunted primarily for food, but they often get caught as a by-catch in fishing expeditions. Question: The horn shark gets its name for _ . Options: A: its small size B: its large eyes C: its two large spines D: its brown color with spots
A: C

Q: Read the article and select the best answer. Article: Hundreds of Chinese officials are to be sacked or demoted for their part in a vaccine scandal that has added to discontent at poor oversight of food and drug safety, especially relating to children. Xinhua, the state news agency, said late on Wednesday that 357 officials are to face punishment, with 192 criminal cases already filed and 202 people detained after improperly stored or transported vaccines were sent to 59 health institutions. This is the latest in a string of food and drug safety scandals in a country where parents often import products for infants and babies from overseas to ensure quality. Many remember with fear the 2008 milk powder scandal, in which infant formula laced with melamine caused at least six deaths and 300,000 children to fall ill. Beijing last month made public an illegal operation in eastern Shandong province in which a hospital pharmacist and her daughter traded $88m in vaccines that may have been compromised because they were expired or improperly stored or transported. The China Food and Drug Administration said, however, that the vaccines posed no greater than the normal risk to patients. "We don't see that the vaccines' effectiveness has been reduced," added the health watchdog in a report. Nonetheless, health officials fear a backlash against Chinese-manufactured vaccines, which already have a reputation for being more dangerous than those made overseas. Wang Yuedan, deputy director of Peking University's immunology department, said the key to evaluating risks is to check whether package seals are broken or for pollution with micro-organisms. "The vaccines in the Shandong case don't have those problems," he said. Those vaccines had been subject to higher than normal temperatures that could have lowered their effectiveness and reduced their protective value. But the official investigation showed the vaccines "are still effective", he said. Beijing, which publicized the affair almost a year after it was exposed, and several years after it started, appeared eager to show... Question: According to Wang Yuedan's opinion, the vaccines in Shandong _ . Options: A: were polluted by micro-organisms. B: were resistant to high temperature. C: decreased their value of protection D: were still effective
A: C

Q: Read the article and select the best answer. Article: "Children who eat less salt and drink fewer sugar-sweetened soft drinks may significantly lower their risks of obesity," researchers recently reported in the journal Hypertension. "Sugar-sweetened soft drinks are a significant source of calorie intake in children," said Feng J. He, a researcher at St George's University of London, England. "It has been shown that sugar-sweetened soft drink consumption is related to obesity in young people." They wanted to know whether there is a link between salt intake and sugar-sweetened soft drink consumption. Dr He and colleagues analyzed data from a 1997 national survey of more than 2,000 people between 4 and 18 in Britain. "We found that children eating a lower-salt diet drank less fluid," said He. "From our research, we estimated that 1 gram of salt cut from their daily diet would reduce fluid intake by 100 grams per day." The researchers also found that children eating a lower-salt diet drank fewer sugar-sweetened soft drinks. From their research, they predicted that reducing salt intake by 1 gram each day would reduce sugar-sweetened soft drink consumption by 27 grams per day, after. "If children aged 4 to 18 cut their salt intake by half, there would be a decrease of about two sugar-sweetened soft drinks per week per child, so each child would decrease calorie intake by almost 250 kilocalories per week," Dr He said. In previous studies, researchers found that a low-salt diet lowers blood pressure in children, and prevents the development of high blood pressure later in life. "Both high blood pressure and obesity increase the risk of having strokes and heart attacks," Dr He said. Dr He recommends that parents check labels and choose low-salt food products. "Small reductions in the salt content of 10 to 20 percent cannot be detected by the human salt taste receptors and do not cause any technological or safety problems," Dr He said.
