The following conversation is between Susan Russell-Robinson from the US Geological （地质学的）Survey and Barbara Reynolds from USA Today .
Q: Why , after 600 years of no activity , did Mount Pinatubo in Philippines erupt（喷发）in 1991 ?
A: Volcanoes （火山）each have their own eruption styles . This volcano probably has a rule which makes it erupt in the order of every 500 to 1000 years , but a volcano in Hawaii seems to erupt every year , and some of the Alaskan volcanoes might erupt every 10 or 20 years .
Q: So nothing caused it ?
A: There’s nothing out of the ordinary . If you were to take an ordinary calendar year , 50 to 75 or 80 volcanoes erupt around the world every year . There are 20 to 30 volcanoes every month that show signs of unrest . That might be a full-blown eruption or a whole host of activities like that .
Q: What is “the ring of fire” ?
A: If you look at where active volcanoes are placed around the world , there are somewhere between 500 and 600 of them . There is what appears to be almost a necklace that goes around the Pacific Ocean . It makes a ring where 60% of the world’s volcanoes lie .
Q: Why such a concentration（集中）there ?
A: That’s based on a theory that the oceans and the continents are like separate pieces . When they move , one might ride up over the other one . In this case , the Pacific Ocean goes under the continents and when that happens it seems to produce magma （熔岩）at depth and then you have volcanoes in the same ring .
64．What kind of writing do you think this passage is ?
A．A text taken from a geography book . B．An interview published in the press .
C．A conversation carried out in a film . D．An oral test recorded as an example .

A．The movement of the surface of the earth makes it possible.
B．The Pacific Ocean produces magma and presses it everywhere.
C．The oceans and the continents are separated from each other.
D．The earth’s surface around the Pacific is thinner than any other part.
66．Barbara Reynolds’ main purpose here is .
A．to show how dangerous volcanoes are to the world
B．to learn what signs a volcano gives us before its eruption
C．to warn the world of the existence of “the ring of fire”
D．to introduce some general idea of volcanoes to the public

The human body is a living machine , and , like all machines , it needs “fuel” (燃料) to supply it with energy . This is provided by the food we eat . But how much do we need to stay healthy ?
The energy value of food is usually measured in calories . A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different , as the pictures show . Also , the number of calories you use at any one moment normally depends on the activity you are in . For example , you need more calories for standing than for sitting , more for running than for walking , and so on .
The energy in food is in the form of three kinds of chemical materials-carbohydrate （碳水化合物）, protein（蛋白质）and fat . Carbohydrate provides 3.8 Cal/gm , protein4.0 Cal/gm , and fat 8.8 Cal/gm . Each food contains different amount of these materials , as the round pictures show .

56．The amount of calories supplied by equal amounts of milk , rice , and peanuts is the largest in the case of .
A．milk B．rice C．peanuts D．rice or peanuts
57．Choose one statement from among A-D that agrees with the passage and the pictures above .
A．You need more calories for swimming than for mountain climbing .
B．Food contains energy in the form of carbohydres , proteins and fuel .
C．Different people need different amounts of energy depending on their age , sex and the activities they are in .
D．3 grams of milk provides 16.6 calories because carbohydrate provides 3.8 Cal/gm , protein 4.0 Cal/gm and fat 8.8 Cal/gm .
58．This article mainly tells us .
A．all the energy is in food
B．the human body needs energy
C．the number of calories depends on your activity
D．we must only eat peanuts to get calories

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically（身体上）.
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale（秤）instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
56. From Paragraph 1, we learn that ________.
A. diet products fail to bring out people’s potential
B. people have difficulty in choosing diet products
C. diet products are misleading people
D. people are fed up with diet products
57. One psychological effect of diet products is that people tend to _____.
A. try out a variety of diet foods B. hesitate before they enjoy diet foods
C. pay attention to their own eating habits D. watch their weight rather than their diet
58. In Paragraph 3, “gain comes without pain” probably means ______.
A. losing weight is effortless B. it costs a lot to lose weight
C. diet products bring no pain D. diet products are free from calories
59. Diet products indirectly harm people physically because such products ______.
A. are over-consumedB. lack basic nutrients
C. are short of chemicals D. provide too much energy
60. Which of the following shows the structure of the passage?

Visitors worry that London is an expensive city but there really are so many things to do for

free in London from museums and galleries to free music and walking tours.
Art Galleries
Tate Modern and Tate Britain are exceptional national art galleries housing some of the finest artworks in the world. Tate Modern focuses on contemporary art while Tate Britain displays British Art from the sixteenth century to the present day.
Museums
All of London's major museums are free, but most offer some special exhibitions for a fee. My favorite is the Museum of London where you can learn the history of London from Roman times to today. Other great major museums are the British Museum, the V&A, the Science Museum, and the Natural History Museum. Oh, and I love the Geffrye Museum. And the Horniman Museum. Now I can't decide which is the best!
Many of London's major art galleries and museums are open in the evening and often have special evening events. This can be a great way to relax at the end of a busy day seeing the sights. The main London galleries and museums are air-conditioned so it can be a wonderful way to cool down in the height of summer in the city. Galleries and museums are not open late every night so here is a handy list to help you plan your days and evenings.
Royal Parks
Many people say the Queen Mary's Rose Gardens in Regent's Park is their favorite spot in London, and who am I to argue? I would also recommend St. James's Park as it offers one of the best views of Buckingham Palace. Hyde Park is enormous and includes the ever popular Diana Memorial Fountain and the Peter Pan Statue.
There are often free talks and guided walks in the royal parks so do check the What's On section of the Royal Parks website.
Changing of the Guard
No visit to London is complete without seeing this military tradition. The Queen's Guard in London changes in the Forecourt inside the gates of Buckingham Palace at 11:30am every day in the summer and every other day in the winter. Get there early and view the spectacle from outside the front gates.
