Questions 31 to 35 are based on the following passage:
Even as Americans have been gaining weight, they have cut their average fat intake from 36 to 34 percent of their total diets in the past 15 years. And indeed, cutting fat to control or lose weight makes sense. Fat has nine calories per gram. Protein and carbohydrates（碳水化合物） have just four. Moreover, the body uses fewer calories to metabolize fat than it does to metabolize other foods. Compared with protein and carbohydrates — which break down into amino acids and simple sugars, respectively, and can be used to strengthen and energize the body —— dietary fat is more easily converted to body fat. Therefore, it’s more likely to stay on buttocks, thighs and bellies.
But cutting fat from your diet doesn’t necessarily mean your body won’t store fat. For example, between nonfat and regular cookies, there’s trivial difference in calories because manufacturers make up for the loss of fat by adding sugar. Low-fat crackers, soups and dressings can also be just as high in calories as richer versions. No matter where the calories come from, overeating will still cause weight again. The calories from fat just do it a little quicker. A Wisconsin computer programmer who decided with a diet coach to eat only 40 grams of fat a day learned the lesson firsthand. He wasn’t losing weight. Then he showed his food diary to his coach and revealed he’d been eating half a pound of jelly beans a day. “They don’t have any fat,” he explains. But they had enough sugar to keep him from shedding an ounce.
Nonfat foods become add-on;foods. When we add them to our diet, we actually increase the number of calories we eat per day and gain weight. That was borne out in a Pennsylvania State University study. For breakfast, Prof. Barbara Rolls gave two groups of women yogurt that contained exactly the same amount of calories. One group’s yogurt label said “high fat”—the other, “low fat.” The “low fat” yogurt group ate significantly more calories later in the day than the other group. “People think they’ve saved fat and can indulge themselves later in the day with no adverse consequences,” says Richard Mattes, a nutrition researcher at Purdue University. “But when they do that, they don’t compensate very precisely, and they often end up overdoing it.”

Questions 36 to 40 are based on the following passage:
The plumes of ash came billowing from Mount Etna on July 17 at precisely 1:33 p.m., followed by 300-foot blasts of lava. Below, in the resort town of Nicolosi, Italy, anxious residents prayed for protection. But scientists were jubilant.
“ Three minutes,” gushes Gene Ulmer, a Temple University geologist. “That’s all they missed by.” Not only did Ulmer witness the eruption (which killed no one), he was in Nicolosi the previous night when European volcanologists（火山学家） predicted that Mount Etna would erupt at 1:30 p.m.— one of the most accurate predictions in history.
Scientists have historically had little success in predicting eruptions. There are instruments to monitor the geophysical changes that may suggest a volcano is ready to blow—increase in tremors, alterations in the mountain’s tilt, or changes in the resistance of th
[1] [2] [3] [4] 下一页
e earth surrounding it. Other instruments track volcanoes’ chemical compositions, because rising levels of ammonia, carbon dioxide, sulfur dioxide, water and other substances can also herald eruptions. But none of these instruments has done particularly well.
So scientists have taken to monitoring as many different aspects of volcanic activity as possible. This broader approach appears to have yielded the stunningly accurate results at Etna. “We may have finally found the right combination of instrument to monitor volcanoes—and save lives,” says Ulmer.
It is, of course, possible that the Etna team just got lucky. Nonetheless, Ulmer says, “all of us in volcanology are very excited.”
36. Volcanologists were surprised by __.
A) the accuracy of their own predictions of eruption of Mount Etna
B) the eruption of Mount Etna
C) the instruments they had used
D) the ash and smoke of Mount Etna

A) Instruments to monitor the geophysical changes.
B) Instruments to track volcanoes’ chemical compositions.
C) The combinations of instruments.
D) None of them.
38. What does the word “jubilant” mean according to;the context?
A) Upset. B) Filled with great joy.
C) Disappointed. D) Accurate.
39 . What is the main idea of the passage?
A) Though Mount Etna erupted as European volcanologists predicted, it was just a coincidence.
B) Scientists succeeded in finding the instruments to predict eruption.
C) Lots of scientists witnessed the Eruption of Mount Etna.
D) Scientists predicted accurately the eruption of Mount Etna.
40. What’s the possible title for this passage?
