Passage 85

(河南省郑州外国语学校2010届高三上学期第三次月考)

(C)

Schools have been blamed for giving kids access to soda in vending machines (自动售货机).But new data suggest that school soft drink sales may not be an important factor in how much soda kids drink.

In the current issue of The Journal of Nutrition Education and Behavior, researchers compared soda consumption among nearly 500 students in Maine who attended seven schools over two school years. Four of the schools cut back on soft drink availability at the schools, while three of the schools made no changes.

All the students were drinking less soda by the end of the study period, but there were no meaningful differences in overall soft drink consumption among the different schools. The data suggest that limiting soft drink availability at school doesn’t result in meaningful changes in drink consumption patterns. While there were no changes in overall soda consumption, there was a notable shift in diet soda drinking among girls. If the school cut back on soda availability, girls were less likely to drink diet soda, compared to girls in schools that made no changes.

The data are the latest to suggest that schools may not play as big of a role in kids’ poor eating habits as widely believed. Last year, The American Journal of Public Health published a provocative (引起争论的) study showing that childhood weight problems often get worse in the summer, when kids are out of school.

Data from kindergarteners and first graders found that body mass index (指数) increased two to three times as fast in summer as during the regular school year. Minority children were especially at risk, as were children who were already overweight.

Even children who were too thin and needed to gain weight appeared to have better eating habits during the school year. They actually gained more weight while in school and less in the summer.

Even so, much of the focus on childhood nutrition and obesity (肥胖) remains in the nation’s schools. Today, The Times reported that even the school bake sale is disappearing as districts impose strict standards on the food served on school grounds.

Passage 84

(山东省潍坊市2010届高三上学期阶段性测试)

A

Climate change has caused the disappearance of ice in Antarctic. It will not only do harm to wildlife in the area but also cause levels of oceans and seas around the world to rise. The old city of Venice, Italy has long been threatened by rising sea levels. Its old buildings, built on a body of water called a lagoon, are slowly “sinking”. When the city was founded about one thousand six hundred yours ago, the water level was almost two meters lower than it is today.

   Mount Kilimanjaro in northeastern Tanzania is the highest point in Africa, with five vegetation zones and many kinds of animals. The ice glaciers on the mountain are disappearing very quickly. This will have a bad effect on the mountain’s plants and animals and on Tanzania’s travel industry. Also, a valuable record of thousands of years of weather history will also be lost if the ice melts. Scientists study pieces of the glacier to know the weather thousands of years ago.

   In the United States, the ice in the Glacier National Park in Montana may soon completely disappear because of climate change. In 1950, there were about 150 glaciers in the park. However there are only 26 glaciers remaining today. Scientists say that the glaciers will be gone by 2030. Many kinds of plants and animals in this mountain park are also disappearing.

  Rising sea temperatures are greatly harming the Great Barrier Reef in Australia. In some areas, healthy yellow, brown and green reefs have turned white. The coral whitens when it becomes breathless because of high temperatures. Its food also becomes less and less because the water is deepening.

  These places are included in the book called “Disappearing Destinations: 37 Places in Peril and What Can Be Done to Help Save Them.” It aims to call on the world to protect these places of interest in danger.
