Flying over a desert in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's flight one of the scientists wrote in his notebook, "Look here for probable metal." Walking across hilly ground, four scientists reported, "This ground should be searched for metals." From an airplane over a hilly wasteland a scientist sent back by radio one word "Uranium". None of the scientists had X-ray eyes: they had no magic powers for looking down below the earth's surface. They were merely putting to use one of the newest methods of locating minerals in the ground -- using trees and plants as signs that certain minerals may lie under the ground on which the trees and plants are growing. This newest method of searching for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface. At Watson Bar Creek, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was carefully marked. In a scientific laboratory the parts of the forest trees were burned to ashes andtested. Each small part was examined to learn whether there were minerals in it. Study of the roots, branches and seeds showed no silver. But there were small amount of gold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches. If the trees indicated that there was no gold in the ground, the scientists wouldn't spare money to pay for digging into the ground. Which of the following might be the best title for this passage? A) Scientists searching for treasure with special equipment. B) New methods of doing geological study. C) Gold could be found in trees and plants. D) A new method of searching for minerals.

Ques: When the famous dancer Fred was interviewed for a job by a Hollywood producer , the movie Expert turned him down, saying,"Can't sing. Can't act. Dances a little." Here's another stupid mistake. When the great scientist Albert Einstein was at school, his teachers considered him rather dull. And a final story, the famous Polish pianist Paderewski was told by a teacher that he'd never be a success as a performer because the middle finger on each hand was too short. What lessons can be drawn from these three experiences? First, true genius cann't be suppressed .For some reason or other it works its way out. Second, early judgments of a person's abilities may be unfair or just wrong. Third, when there is a real determination to succeed, obstacles fall by the wayside. The famous motto "ad astra per aspera" can be translated as " To the stars through hardships". Astaire, Einstein and Paderewski proved their critics wrong. The writer of the passage thinks that the reader _ . A) Knows that the three men were successful men B) Dreams to become like one of the men some day C) Sympathizes with the poor teachers of the three men D) Knows that Fred Astaire was an actor famous for performing Shakespeare's plays

Almost 80% of the Americans have stated their opposition to cloning pet animals such as cats and dogs, yet companies still try to make a business out of selling cloned pets. Pet cloning has been promoted as a way to "bring back" or "copy" a beloved companion animal. However, studies have shown that cloning remains an experimental technology with many failures. Behind each lovely picture of a cloned cat or dog lie hundreds of animals that were kept in lab cages, receiving bad treatment to produce just that one cloned animal. For all that, you end up with a cloned animal who is unlikely to appear like the original physically or behaviorally and may experience serious health problems. Also, while pet cloning companies are charging customers up to $150,000 for a cloned pet, millions of homeless animals of the same species are available in US animal shelters for around $100. Unfortunately, most of these animals are killed for lack of adopting homes. With No Pet Cloning campaign, the American Anti-Vivisection Society (AAVS) tries to protect both animals and people from harm. They campaigned until the US companies that sold cloned animals closed their doors. First it was Genetic Savings & Clone Inc. and then it was BioArts International. When BioArts was closed, its owner, Lou Hawthorne, finally had to _ the problems of pet cloning. According to Hawthorne, he has seen numerous failures during his pet cloning attempts, "One clone----which was supposed to be black and white----was born greenish-yellow where it should have been white (we still have no good explanation for how that happened)." The AAVS is educating the public about the animal suffering and is seeking regulation of cloning activities. They will continue to take the lead in protecting animals from the threats of pet cloning. From the passage, we know that _ . A) pets are often deserted by their owners B) more and more people have joined the AAVS C) most American are against cloning pet animals D) the American Anti-Vivisection Society is supported by the government
