This process is key to establishing later lines of research, so try to get as much information as possible, bearing in mind that some of what you hear may not be strictly accurate — memories can fade over time, whilst many of our relatives are referred to by “pet” names that are not the same as the ones they were born with. You will almost certainly hear stories that may have been passed through the family for generations, and it will be your task to check if they are true. Take some time to see if anyone has already done some family history. Even if you do discover that you are not the first to chronicle the story of your clan, check the details that have been uncovered already; it can’t hurt to ensure that the details are actually correct.Once you’ve exhausted your family’s store of knowledge, it’s time to look for other things, such as personal letters, photographs, official documents, school reports and even old uniforms, which can reveal great detail about the past and add color to the lives of our forebears.You will quickly find that the processes outlined above generate a great deal of data, and the best way to keep track of where you are is to organize it in a highly visual fashion by compiling a family tree. This is a diagram that shows how all your family members are related to one another. Start with yourself; if you are married, place your partner’s name alongside yours and connect them with the symbol ‘=’ or ‘m’ to denote marriage, and put the date next to it. If you have children, they sit underneath your name on the family tree and represent the generation below you. Similarly, your parents go above you, and their parents — your grandparents — above them. Each time you work back a generation, you double the number of direct ancestors; thus you have four grandparents, eight great-grandparents and so on.50. What is the writer’s main purpose in writing this passage?A. To convince the reader that it’s necessary to build a family tree.B. To encourage the reader to find more about their family tree.C. To remind the reader that accuracy matters for a family tree.D. To teach the reader how to build a family tree step by step.

Directions: There are 2 passages in this section. Each passage is fallowed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre. Questions 46 to 50 are based on the following passage. Sugar shocked. That describes the reaction of many Americans this week following revelations that, 50 years ago, the sugar industry paid Harvard scientists for research that shifted the focus away from sugar's role in heart disease-and put the spotlight (注意的中心)squarely on dietary fat. What might surprise consumers is just how many present-day nutrition studies are still funded by the food industry. Nutrition scholar Marion Nestle of New York University spent a year informally tracking industry-funded studies on food. "Roughly 90% of nearly 170 studies favored the sponsor's interest," Nestle tells us. Other systematic reviews support her conclusions. For instance, studies funded by Welch Foods-the brand behind Welch's 100% Grape Juice-found that drinking Concord grape juice daily may boost brain function. Another, funded by Quaker Oats, concluded, as a Daily Mail story put it, that "hot oatmeal ( 燕麦粥) breakfast keeps you full for longer. " Last year, The New York Times revealed how Coca-Cola was funding well-known scientists and organizations promoting a message that, in the battle against weight gain, people should pay more attention to exercise and less to what they eat and drink. Coca-Cola also released data detailing its funding of several medical institutions and associations between 2010 and 2015. "It's certainly a problem that so much research in nutrition and health is funded by industry," says Bonnie Liebman, director of nutrition at the Center for Science in the Public Interest. "When the food industry pays for research, it often gets what it pays for." And what it pays for is often a pro-industry finding.

"Rely on health experts who've reviewed all the evidence," Liebman says, pointing to the official government Dietary Guidelines, which are based on reviews of hundreds of studies. "And that expert advice remains pretty simple," says Nestle. "We know what healthy diets are--lots of vegetables, not too much junk food, balanced calories. Everything else is really difficult to do experimentally. " 47. What does Marion Nestle say about present-day nutrition studies?A. They took her a full year to track and analyze.B. Most of them are based on systematic reviews.C. They depend on funding from the food industries.D. Nearly all of them serve the purpose of the funders.
