　　Enjoying an iced coffee? Better skip dinner or hit the gym afterwards, with a cancer charity warning that some iced coffees contain as many calories as a hot dinner。

　　The World Cancer Research Fund (WCRF) conducted a survey of iced coffees sold by some popular chains in Britain including Starbucks, Caffe Nero and Costa Coffee to gauge the calories as studies increasingly link obesity with cancer。

　　The worst offender - a coffee from Starbucks -- had 561 calories. Other iced coffees contained more than 450 calories and the majority had an excess of 200.

　　Health experts advise that the average woman should consume about 2,000 calories a day and a man about 2,500 calories to maintain a healthy weight. Dieters aim for 1,000 to 1,500 calories a day。

　　"The fact that there is an iced coffee on the market with over a quarter of a woman's daily calories allowance is alarming," Dr Rachel Thompson, science programme manager at London-based WCRF, said in a widely-reported statement。

　　"This is the amount of calories you might expect to have in an evening meal, not in a drink."

　　The WCRF has estimated that 19,000 cancers a year in Britain could be prevented if people lost their excess weight with growing evidence that excess body fat increases the risk of various cancers。

　　"If you are having these types of coffee regularly then they will increase the chances of you becoming overweight, which in turn increases your risk of developing cancer, as well as other diseases such as heart disease." she added。

　　33. What warning did some health experts give?

　　34. What does the author suggest people do after they have an iced coffee?

　　35. What could British people expect if they maintain a normal body weight according to the WCRF?

　　Psychologists are finding that hope plays a surprisingly vital role in giving people a measurable advantage in rounds as diverse as academic achievement, bearing up in tough jobs, and coping with tragic illness. And, by contrast, the loss of hope, is turning out to be a stronger sign that a person may commit suicide than other factors long thought to be more likely risks. ‘Hope has proven a powerful predictor of outcome in every study we've done so far,’ said Doctor Charles R. Snyder, a psychologist, who has devised a scale to assess how much hope a person has. For example, in research with 3920 college students, Doctor Snyder and his colleagues found that the level of hope among freshmen at the beginning of their first semester was a more accurate predictor of their college grades, than were their SAT scores or their grade point averages in high school, the two measures most commonly used to predict college performance. ‘Students with high hope set themselves higher goals and know how to work to attain them,’ Doctor Snyder said. ‘When you compare students of equivalent intelligence and past academic achievements, what sets them apart is hope.’ In devising a way to assess hope scientifically, Doctor Snyder went beyond the simple notion that hope is merely the sense that everything will turn out all right. ‘That notion is not concrete enough and it blurs two key components of hope,’ Doctor Snyder said, ‘Having hope means believing you have both the will and the way to accomplish your goals, whatever they may be.’

　　Among global warming’s most frightening threats is the prediction is that the polar ice-caps will melt, raising sea level so much that coastal cities from New York to Los Angles to Shanghai will be flooded. Scientists agree that key player in this scenario is the west Antarctic ice sheet, a Brazil-size mass of frozen water that is much as 7000 feet thick. Unlike floating ice shelves which have little impact on sea level when they break up, the ice sheet is anchored to bedrock will blow the sea surface. Surrounded by open ocean, it is also vulnerable, but Antarctic experts disagree strongly on just how unstable it is. Now, new evidence reveals that all or most of the Antarctic ice sheet collapsed at least once during the past 1.3 million years, a period when global temperatures probably were not significantly higher than they are today. And the ice sheet was assumed to have been stable. In geological time, a million years is recent history. The proof, which was published last week in Science, comes from a team of scientists from Uppsala University in Sweden and California Institute of Technology who drew deep holes near the edge of ice sheet. Within samples collected from the solid substances lying beneath the ice. They found fossils of microscopic marine plants which suggest that the region was once open ocean not solid ice. As Herman Engleheart, a co-author from the California Institute of Technology says the west Antarctic ice sheet disappear once and can disappear again。 Science, comes from a team of scientists from Uppsala University in Sweden and California Institute of Technology who drew deep holes near the edge of ice sheet.
