B. Students are required to perform community service jobs. C. Many high school students enjoy their volunteer work. D. Students with difficulties can choose not to volunteer. Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions How long will a baby born today live? 100 years? 120 years? Scientists are studying genes that could mean long life for us all. There are already many, many people who have passed the landmark age of 100. In fact, there are now so many healthy, elderly people that there’s a name for them: the wellderly. These are people over the age of eighty who have no major illnesses, such as high blood pressure, heart disease or diabetes. There are many scientific studies of communities where healthy old age is typical. These include places like Calabria in southern Italy and the island of Okinawa in Japan. In Calabria, the small village of Molochio has about 2,000 inhabitants. And of these, there are at least eight people over a hundred years old. When researchers ask people like this the secret of their long life, the answer is almost always about food and is almost always the same: ‘I eat a lot of fruit and vegetables.’ ‘I eat a little bit of everything.’ ‘I neither smoke nor drink.’ In the past, scientists looked at things such as diet and lifestyle for an explanation of long life, these days they are also looking at genetics. Researcher Eric Topol says that there must be genes that explain why people are protected from the effects of aging process. The new research into long life did scrutinize groups of people who have a genetic connection. One interesting group lives in Ecuador. In one area of the country there are a number of people with the same genetic condition. It’s called Laron syndrome. These people don’t grow very tall – just over one metre. But Laron syndrome also give them protection against cancer and diabetes. As a result, they live longer than other people in their families. Meanwhile, on the Hawaiian island of Oahu, there’s another group of long-lived men, Japanese-Americans. They have a similar gene to the Laron syndrome group. Back in Calabria, researchers constructed the family trees of the 100-year-old people. They looked at family information from the 19th century to today. It is concluded that there are genetic factors that give health benefits to the men. This is a surprising result because generally in Europe, women live longer than men. So what really makes people live longer? It seems likely that it is an interaction of genes, the environment and probably a third factor – luck. Question 34: Which of the following is NOT true about the Laron syndrome? A. This syndrome is a health problem for groups of people in Ecuador and Hawaii. B. It is the result of a genetic condition. C. People diagnosed with this syndrome are prone to diabetes. D. Ecuadorians having Laron syndrome are approximately one metre tall. Question 35: Which of the following is the best title for the passage? A. The Secrets of A Long And Healthy Life B. Tips To Increase Life Expectancy C. How To Live More Than 100 Years? D. Human Lifespan Is Determined by Genetics Question 36: Who are the wellderly? A. They are old people with health problems. B. They are young people with health problems. C. They are healthy young people. D. They are healthy old people. Question 37: Which of the following can be inferred from the passage? A. Different factors lead to a healthy old age. B. More European men live to a healthy old age than women. C. In the past, more people lived to a healthy old age. D. We will all live to at least 100 years. Question 38: According to paragraph 3, _________. A. scientists have been studying places where only one healthy old person lives B. scientists have been studying places where there is no healthy old person C. scientists have been investigating places where most people live to be a hundred D. scientists have conducted many studies of places where healthy old age is normal
