Q: Read the article and select the best answer. Article: Like many languages spoken by people, Ayapaneco is dying. Only two people in the world still speak it, and they won't talk to each other. Spoken in Mexico for centuries, Ayapaneco is one of 68 surviving languages in the mainly Spanish-speaking nation. The two speakers are Manuel Segovia and Isidro Velazquez. Though they live only 500 meters from each other in the village, the two men seldom talk to each other. Daniel, an American expert, who is working to make a dictionary of Ayapaneco, says the two men "don't have a lot in common," and that Segovia can be "active" while Velasquez tends to mind his own business and stay at home. While Segovia still speaks to his wife and son in Ayapaneco, neither of them can manage more than a few words. Velasquez hardly speaks his native tongue any more. Daniel is working to preserve the language in dictionary form before its last surviving speakers pass away. According to Daniel, Ayapaneco and the other languages began dying out with the introduction of public Spanish education in the mid-20thcentury. For decades, local children weren't allowed to speak anything else. Many people to cities, starting in the 1970s, also helped the dying out of native languages. Ayapaneco is the name given to the language; Segovia and Velazquez call it "Nuumte Oote", which means "true voice". Neither man, however, speaks the same language. The dictionary will contain two versions of the language when it comes out later this year. Those behind the dictionary aren't the only ones trying to save Ayapaneco. The National Language Institute plans to hold classes so that Segovia and Velasquez can pass on what they know to children. It is thought that there are about 6,000 languages spoken on earth and that about half will disappear over the next 100 years. Let's hope the "true voice" isn't one of them. Question: From the text we learn that the author _ . Options: A: agrees that it is natural that Ayapaneco should die out B: thinks Daniel's effort to preserve Ayapaneco won't work C: thinks highly of Ayapaneco and wants people to learn it D: hopes that Ayapaneco will not die out in the future

Q: Read the article and select the best answer. Article: The 2016 Summer Olympics, officially known as the Games of the XXXI Olympiad, is a major international multi-sport event. The host city of the Games will be Rio de Janeiro, Brazil as announced at the 121st IOC Session held in Copenhagen, Denmark, on October 2, 2009. They are scheduled to be held from August 5 to 21, 2016, making them the first Summer Olympics to be held during the host city's wintertime. This will mark the first time a South American city hosts the event, and also the first time a Portuguese-speaking country hosts the event. "The world has recognized that the time has come for Brazil," said President Luiz Inacio Lula da Silva. There have been questions about Rio's bid because of the high level of violence which so often scars the city's image, but in one glorious moment that was all set to one side for a truly Brazilian party. In his speech earlier, President Lula had promised, "Rio will deliver an unforgettable Games. You will see for yourselves the passion, the energy and the creativity of the Brazilian people." "It will not be just Brazil's Games but South America's. It will serve to inspire the 180 million young people on the continent. It is time to redress the balance. It is time to light the Olympic flame in a tropical country." Rio plants to stage all the competitions inside the city, bringing "dynamics to the Games and facilitating the athletes' interaction," according to the bid website. The 2016 Summer Olympic programme features 28 sports and a total of 42 disciplines. Question: Where did Brazil win the bidding for the 2016 Olympics? Options: A: In Rio de Janeiro, Brazil. B: In Copenhagen, Denmark. C: In a South African city. D: In a tropical country.

Q: Read the article and select the best answer. Article: Even if we have an extremely healthy diet and lifestyle, the human body is programmed to wear out at a maximum of about 120 years, and usually less. We all have a biological clock inside us which determines the moment when our organs cease to function properly. This is because our cells have stopped renewing themselves and our body can no longer repair itself. This is also the moment when we are more likely to begin to suffer from the diseases of old age such as arthritis and Alzheimer's. However, rapid advances in DNA research are beginning to throw light on the secrets of the ageing process. By the end of this century we could literally have the power of life over death. Although it has long been accepted that humans have a fixed lifespan, it is also a fact that certain other organisms, such as reptiles and amphibians, appear to _ . The only reason we do not see 500-year-old alligators is because in the wild their lives are always in danger, from man, from pollution and from other animals. When they are kept in zoos they do not seem to age at all after they are fully grown. The same is true of some species of fish, which grow indefinitely and show no signs of ageing. The existence of animals with no fixed lifespan seems to indicate that an age gene really does exist. It is this gene which scientists are searching for, which may delay or repair damage to the body caused by ageing. Another new area of research involves the oxidation theory, which says that ageing is caused by the same process that makes iron rust. In controlled experiments, the lifespans of certain animals were shown to be lengthened with anti-oxidants; for example, the lifespan of mice can be increased by 30%. Antioxidants are already being used in face creams and other cosmetics, and they are likely to play an important part in keeping people physically young. Perhaps the most immediate advance we are likely to see in the battle to halt the ageing process will be organ replacement. By the year 2020 it is likely that we will be replacing... Question: When all humans reach a certain age, _ . Options: A: they suffer the effects of their diet and lifestyle B: the organs stop to perform appropriately C: their cells continue to renew themselves D: they develop arthritis and Alzheimer's
