One reason they may feel that way is that coffee contains caffeine . Caffeine occurs naturally in coffee, tea, and cocoa beans, which are used to make chocolate. But now food makers are adding it to many products, from potato chips to water. The US government is especially worried about the problem. That's why the Food and Drug Administration (FDA) is studying the health effects of caffeine on young people. Studies show that too much caffeine can make people nervous and unable to sleep. What's more, caffeine is habit-forming. Those who consume it regularly and stop suddenly may experience headaches and feel tired. One of the biggest concerns is the large amount of caffeine added to so-called energy drinks, like Red Bull. A 12-ounce can of cola has about 35 milligrams of caffeine. A similar serving of Red Bull contains more than three times that amount. The Institute of Medicine is also working on caffeine-safety measures. "Teenagers should not drink beverages that contain caffeine. They should be aware of caffeine's effects on health and on how the brain works. Take, for example, teenagers who consume caffeine to stay awake and study for a test. They will remember less of what they just studied," said Stallings, a member of the institute. Companies that make products with added caffeine claim they do not advertise them to kids. However, there is no law to stop children from buying them. So the FDA needs to set limits on caffeine, especially in energy drinks. As for added caffeine in foods, the government should just say no. If not, the amount of caffeine should be printed on food labels to remind consumers. The government must do that. Doctors say kids should avoid caffeine. If you need extra energy, try these natural boosters: eat right, exercise, and get plenty of sleep. Question: What is the US government particularly concerned about? Options: A: The fact that coffee contains caffeine. B: The measures of avoiding caffeine's effects. C: The practice of adding caffeine to foods. D: The practice of using caffeine to make chocolate.

(Question)
Read the article and select the best answer. Article: The World Association of Zoos and Aquariums (WAZA) is an international organization that brings together zoos and aquariums to cooperate in efforts to advance the respectful, humane treatment of animals in our care, and to support the conservation of animals across the globe. WAZA was shocked and disappointed to learn of the inappropriate and damaging content in the new TV show Wonderful Friends, jointly produced by China's biggest zoo & circus company (Chimelong) and one of China's top TV companies (Hunan TV). The show dresses up chimpanzees in human clothes and markets them as "cute pets". The animals are placed in many stressful and harmful situations, in order to create "entertaining" story lines. It is disappointing to note that Chinese pop singer and actress Li Yuchun took part in this show, helping to popularize these misleading and inhumane practices. In one example, a young chimp bit an actress in the face right next to a zoo visitor, and then bit another actor leaving a wound on his hand. WAZA is strongly against practices and shows of this nature. Animals presented in such cruel and unnatural surroundings cannot contribute to serious conservation efforts. Presenting chimpanzees in unnatural and anthropomorphic settings suggests to viewers that they are not endangered and make great pets. Such shows are not only disrespectful to animals, they also lack any sort of conservation purpose. According to the IUCN Red List of Threatened Species, chimpanzees are now considered endangered, and wild populations are declining rapidly. WAZA recognizes that the growing popularity of television programmes such as Wonderful Friends can only increase the already-huge existing demand for chimpanzees as pets. WAZA requests the following: (1) The immediate cancel of this programme and similar shows wherever they may take place; (2) That all animals held in captivity be provided with the highest level of care; (3) That under no circumstances should chimpanzees be imported from the wild just for entertainment purposes. Question: Dressing up chimpanzees in human clothes will make people want to _ . Options: A: raise chimpanzees as pets B: sell chimpanzees in the market C: persuade people into donating money to WAZA D: make chimpanzees feel on equal terms with human beings
(Answer)
A

Ques:Read the article and select the best answer. Article: Nuclear energy has always been controversial. But since the tsunami and nuclear disaster in Fukushima (Japan) last year the issue is back in the headlines. And the world is divided-- some countries are planning more nuclear plants, while others have promised to shut theirs down. After Fukushima, Germany decided to switch off all its nuclear plants by 2022. Switzerland and Italy are also phasing out nuclear power. But France and the United States remain staunch supporters of atomic energy. In fact, almost 80% of France's electricity comes from nuclear power, the highest percentage in the world. And in the US, the Obama administration said it "continues to support the expansion of nuclear power, despite the crisis in Japan." Nuclear supporters claim nuclear power can help the environment. Unlike fossil fuels, nuclear power doesn't create greenhouse gases. So, pro-nuclear countries argue that nuclear power allows them to generate energy without contributing to climate change. Britain's chief scientific adviser (John Beddington) supports this view. He recently said that the world doesn't have the luxury of ignoring nuclear energy. Nuclear power is also relatively cheap. Renewable energy sources such as solar, hydro and wind power may be clean, but they're expensive; and right now, they require a lot of investment. This higher cost of using "green energy" is usually passed onto the consumer. So, while many people may prefer their energy to come from a renewable source, not so many are prepared to pay higher energy bills. _ is of particular concern while the world economy is in such bad shape. The main argument against nuclear energy is that it isn't safe. For a start, nuclear waste is very difficult to dispose of, and remains toxic to humans for thousands of years. And even before Fukushima, there were several high-profile nuclear disasters. The most famous is probably the 1986 Chernobyl disaster, in the Ukraine. The radiation from the meltdown spread all over Europe, affecting thousands. The nuclear energy issue... Question: Which of the following may NOT be the advantage of nuclear energy over other energy sources? Options: A: Nuclear energy doesn't produce any greenhouse gases. B: Nuclear energy can help prevent the climate damage. C: Nuclear energy is more environmental-friendly than other green energy sources. D: Nuclear energy can save the consumers some money, compared to other renewable energies.
