The guidelines advise that both adults and children eat less sugar to stay healthy. According to the WHO, reducing daily sugar intake “reduces the risk of overweight, obesity, and tooth decay (蛀牙)” The guidelines do not apply to the sugars in fresh fruits and vegetables or those that are naturally present in milk. According to the WHO, there is no reported evidence of bad effects of taking in those sugars. Instead, the new guidelines focus on “added” or “free” sugars. These include sugars that are added to certain foods and drinks such as donuts, cookies, candy, and soft drinks. Added sugars are sometimes described as “hidden” sugars because they exist in foods we might not think of as sweets, such as honey. Health experts advise that people look at ingredients on food packages (包装) to help make better decisions. The WHO suggests that people in the United States, Europe, and other Western societies should cut their average sugar intake by about twothirds, or down to just 10% of their total calories. For developing countries, the WHO suggests that sugar intake be reduced to 5%. In the US., adults now get about 11 to 15% of their calories from added, sugars. Children usually get even more. In Europe, sugar intake varies by country. For adults in Hungary and Norway, it is about 7%. In Spain and the United Kingdom, sugar makes up as much as 17% of adults diets. The WHO reports that for children in Europe, sugar intake can be much higher, ranging from about 12% in Denmark, Slovenia, and Sweden, to nearly 25% in Portugal.1According to Paragraph 1, reducing daily sugar intake is_A. dangerous B. importantC. difficult D. unnecessary2Which of the following belong(s) to “hidden” sugars?A. Sugars in fullcream milk.B. Sugars in fresh fruits.C. Honey added to food.D. Sugars in fresh vegetables.3Its implied in Paragraph 4 that people in Western societies_A. dont really like sweet foodsB: are careful about their dietsC. are worried about their healthD. have a high average sugar intake4In which country do children take in the most sugar on average?A. Slovenia. B. Denmark.C. Portugal. D. Sweden.答案与解析世界卫生组织颁发了新的准则。号召人们减少糖的摄取量。1B推理判断题。根据第一段中的.reducing daily sugar intake“reduces the risk of overweight，obesity，and tooth decay可推知，因为减少糖的摄取量可以减少患病的危险，所以很重要。2C细节理解题。根据第三段中的.because they exist in foods we might not think of as sweets，such as honey可知，这里是指人工添加进食品里的含糖食物，故选C。3D推理判断题。根据第四段中的The WHO suggests that people in the United States，Europe，and other Western societies should cut their average sugar intake by about twothirds.可推知，西方国家人们的糖平均摄取量过高。4C细节理解题。根据第五段中的The WHO reports that for children in Europe，sugar intake can be much higher，ranging from about 12% in Denmark，Slovenia，and Sweden，to nearly 25% in Portugal可知，这几个国家中，葡萄牙儿童的糖摄取量最高。CThe Science Learning Centre in London asked 11，000 pupils for their views on science and scientists. Around 70% of the questioned pupils said they did not see scientists as “normal young and attractive men and women.”The research examined why fewer students chose science as their major in universities.Researchers Roni Malek and Fani Stylianadou are completing their research in April but have studied around half the results so far. They found that around 80% of pupils thought that scientists did very “important work”， and 70% thought that they worked “creatively and imaginatively”. Only 40% said they thought that scientists did “boring and unchanging work”. Over three quarters of the pupils thought that scientists were “really brainy people”The research is working as part of Einstein Year. The pupils, who would not like to be scientists, said, “You would always be depressed and tired and not have time for family，”and “they all wear big glasses and white coats, but I dont want to be like that.”Dr Stylianadou said：“These results are worrying for UK science but there is still hope. Young people see science as important and exciting. They dont just want to do it themselves.”“If we can keep young people positive about science and help them to see the full range of scientif
