Article: When people talk about Golden Age in Leadville, Horace Austin Warner Tabor and his second wife, Elizabeth McCourt must be included. Their story is becoming one of the legends of the Old West. H.A.W.Tabor was a school teacher in Vermont. With his first wife and two children he left Vermont in 1855 to settle in Kansas. Perhaps he was attracted by rumors of fortunes to be made in Colorado mines. A few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. "Great deposits of lead are sure to be found here."he said. As it turned out, it was silver, not lead, that was to make Leadville's fortune and wealth. Tabor knew little about mining himself, so he opened a general store selling everything from boots to salt, flour, and tobacco. He often "grubstook" miners, in other words, to supply them with food and supplies, or"grub", while they looked for more. In return he would get a share in the mine if one was discovered. He did this for several years,but nobody he helped ever found anything of value. Finally one day in the year 1878, so the story goes, two miners came in and asked for "grub".Tabor had decided to quit supplying it because he had lost too much money that way. They were persistent, however, and Tabor was too busy to argue with them, " Oh help yourself. One more time won't make any difference," He said and went on selling shoes and hats to other customers. The two miners took $17 worth of supplies, in return for which they gave Tabor a one-third interest in their findings. They picked a barren place on the mountain side and began to dig. After nine days they struck a rich amount of silver. Tabor bought the shares of the other two men, and so the mine belonged to him alone. This mine, known as the "Pittsburgh Mine,"made $300 000 for Tabor in return for his $17 investment. Later Tabor bought the Matchless Mine on another barren hillside just outside the town for $117 000. This turned out to be even more successful than the Pittsburgh, earning $35 000 worth of silver per day at one time. Leadville grew. Tabor became its first mayor.
Question: According to the passage, why was Tabor able to achieve great success in Leadville?
Options: (A) His wise decisions helped him achieve goals. (B) He knew miners there were poor. (C) He succeeded quite by accident. (D) His second wife helped him a lot.

Article: There are more than 100 million cars in the United States. An ordinary car gets less than 15 miles from each gallon of gas. It travels about 10,000 miles each year. In that time, it uses about 650 gallons of gas. In all , automobiles use up some 70 billion gallons of gas a year. That comes out to be four-and-a-half million barrels a day. The importance of saving gas, then, cannot be stressed too much. Let's say, the fuel used by each car could be cut back just 15 percent. This could be done by making fewer trips each day. It could be done by keeping the automobiles in good shape. It could be done through better driving habits. If these were done, the nation's use of fuel would fall by close to two-thirds of a million barrels per day. Everyone can help to save gas. One way is to ride buses. Some could walk to work. Others could ride their bikes. Another way is to share a ride. People could share cars. About one-third of all cars are used for going to and from work. You can go shopping with a friend from time to time. If two people use a car instead of two, they all save. Driving stress would be less, too, with fewer cars on the road. The savings on gas around the nation would come to more than one-half million barrels a day. Still another way to save is by cutting out trips one does not need to take. Can you find one car trip per week that could be done by telephone? Can you combine trips? If each car travelled 10 miles less each week, they could save three-and-a-half billion gallons of gas a year. This comes to nearly 5 percent of the total passenger cars demand for gas. The way people drive decides how much fuel they save. Careful drivers may get 20 percent more miles per gallon than ordinary drivers. They obey the 55-mile-per-hour speed limit. If just one gallon of gas were saved each week for each car in the country, a total of five-and-a-half billion gallons could be saved a year.
Question: Which of the following statements is true about an average car according to the passage?
Options: (A) An ordinary car run a lot more than 10,000 miles with 650 gallons of gas. (B) An ordinary car cannot run more than 15 miles with one gallon of gas. (C) An ordinary car with ten gallons of gas can run more than 150 miles. (D) An ordinary car can run 10,000 miles each year with 70 billion gallons of fuel.

Article: Deng Nannan, 15, used to hate drinking milk for breakfast. But she had to drink it because her mom, as well as many others, said that milk was good for her growing body. Besides, milk and bread made up a convenient diet that saved her parents a lot of time after Deng entered junior school and had to arrive at school early in the morning. After that, Mengniu and Yili became her favorite brands of morning milk and yoghurt after dinner. However, she has been forced to change her diet since the recent milk crisis. Many best-selling milk brands such as Mengniu, Yili and Bright were discovered to contain melamine , which is usually used to make plastic.
