Read the article and select the best answer. Article: One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem ,while the student claimed a perfect score. I was elected as their arbiter( ).I read the examination problem: "Show how it is possible to determine the height of a tall building with the aid of a barometer ." The student had answered: "Take the barometer to the top of the building,attach a long rope to it,lower it to the street,and then bring it up, measuring the length of the rope. The length of it is the height of the building. " The student had really answered the question completely ,but the answer didn't confirm his competence in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and clashed off one, which read: "Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula to calculate the height of the building. " At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others ,and then added5"Probably the best is to take the barometer to the. administrator and said to him,' Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you.," Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did ,but said that he was fed up with high school and college instructors trying to teach him how to think. The name of the student was Bohr who later was famous all over ,the world. He won the Nobel Prize for Physics in 1922. Question: We can learn from the passage that _ . Options: A: instructors can teach students how to think B: arbiters can help students to get high scores C: students should be given more freedom in thinking D: teachers should make students use physical formulas

Read the article and select the best answer. Article: Climatic conditions are delicately adjusted to composition of the Earth's atmosphere. If there were a change in the atmosphere -- for example, in the amounts of atmospheric gases -- the climate would probably change also. A slight increase in water vapor , for example, would increase the heat-keeping capacity of the atmosphere and would lead to a rise in global temperatures. The level of carbon dioxide, CO2, in the atmosphere has an important effect on climatic change. Most of the Earth's incoming energy is short-wavelength radiation , which tends to pass through atmospheric CO2easily. The Earth, however, reradiates much of the received energy as long-wavelength radiation , which CO2absorbs and then goes toward the Earth. This phenomenon, known as the greenhouse effect, can result in an increase in the surface temperature of a planet. An extreme example of the effect is shown by Venus, a planet covered by heavy clouds composed mostly of CO2, whose surface temperatures have been measured at 430~C.If the CO2 content of the atmosphere is reduced, the temperature falls. According to one respectable theory, if the atmospheric CO2concentration were halved, the Earth would become completely covered with ice. Another equally respectable theory, however, states that a halving of the CO2concentration would lead only to a reduction in global temperatures of 3degC. If, because of an increase in forest fires or volcanic activity, the CO2content of the atmosphere increased, a warmer climate would be produced. Plant growth, which relied on both the warmth and the availability of CO2, would probably increase. As a consequence, plant would use more and more CO2. Eventually CO2levels would decrease and the climate, in turn, would become cooler. With reduced temperatures many plants would die; CO2would thus be returned to the atmosphere and gradually the temperature would rise again. Thus, if this process occurred, there might be a long-term oscillation in the amount of CO2present in the atmosphere, with regular... Question: Which of the following questions does the information supplied in this passage try to answer? Options: A: What are the steps in the process that takes place as CO2absorbs long-wavelength radiation? B: How might our understanding of the greenhouse effect be improved if the burning of fossil were decreased? C: What might cause a series of regular increases and decreases in the amount of CO2in the atmosphere? D: Why are there fewer meteorological recording stations in the Southern Hemisphere oceanic zone than atmosphere?

Read the article and select the best answer. Article: On Saturday 17 September 2016, you may catch sight of hundreds of apes running around the streets of London. They'll have been filming a new Planet of the Apes movie, you'll probably think. But in fact, when the starter's pistol sounds for the Great Gorilla Run next year, this highly popular event will have been raising money for thirteen years. People from all over the world will run, jog or walk 8km in gorilla costumes through the capital's streets, passing such iconic landmarks as The Tower of London and St Paul's Cathedral. By the time the last ape crosses the finishing line, the runners will have raised millions for endangered species and education projects in Central Africa. Unusual charity events such as these are a huge trend for raising money for worthwhile causes. If, however, you're looking to really like the idea of running through mud and freezing cold ice, then The Tough Mudder is perhaps what you've been searching for. In this difficult and tiring team event, participants finish a 10 to 12-mile barrier course that tests physical strength and mental courage. It's more about friendship than winning. Over 150 such events worldwide have raised PS5 million. But fundraising doesn't have to involve physical effort. Students at a school in Illinois played Justin Bieber's song 'Baby' over loudspeakers and urged fellow students to pay to stop the song. They needed to raise $1,000 in one week to achieve this. Beyond expectations, they exceeded the goal within three days. Even teachers _ If you want to join the ranks of gorillas next September, you only have to pay PS60 to register. This includes the gorilla suit, which you can keep. If you take part, not only will you have been helping the gorillas and people who depend on their habitat, you'll never have to buy another set of fancy clothes again! Question: Which can be a suitable title for the passage? Options: A: Going Crazy for Charity! B: Protecting Our Rare Animals! C: Competing in Unusual Events! D: Watching Out for Aggressive Animals!
