A couple of years ago, those who forecast that oil price would reach $ 100 a barrel were seen as doomsters. However, now some are predicting $ 200 a barrel.
Had economists been told that oil price would barely pause at $ 100 before reaching the recent peak of nearly $ 127, they would no doubt have forecast terrible economic consequences. But the global economy, though interrupted by the high price of energy, is still chugging along. Meanwhile, inflation has picked up, but the headline rates of inflation (通货膨胀率) in most developed countries are nowhere near the levels seen in the 1970s and 1980s.
There are three explanations for the oil price’s unclear impact. The first is that nowadays developed economies are more efficient in their use of energy, thanks partly to the increased importance of service industries and the diminished role of manufacturing(制造业). According to the Energy Information Administration, the energy intensity of America’s GDP fell by 42% between 1980 and 2007.
A second theory is that the oil-price rise has been steady, not sudden, giving the economy time to adjust. Giovanni Serio of Goldman Sachs points out that in 1973 there was a severe supply shock because of the oil embargo(石油禁运), when the world had to cope with 10%-15% less crude almost overnight. Not this time.
The third explanation turns the argument on its head; rather than oil harming the global economy, it is global expansion that is driving up the price of oil.
The most important factor is the shift in favor of the developing economies. America has responded to high price in familiar fashion: UBS forecasts that demand will drop by 1.1% this year and will be no higher in 2010 than it was in 2004. But the demand from China and other emerging markets is more than offsetting(抵消) this shortfall.What is the passage mainly talking about?
| A．The prediction of economists. | B．The situation of economy |
| C．The increase of oil price | D．The American response to high price |
How many explanations for the oil price’s impact are mentioned in the passage?
| A．Two | B．Three | C．Four | D．Five |
What can we conclude from the passage?
| A．In USA, the demand for oil in 2010 will be very high. |
| B．In USA, the demand for oil in 2010 will be higher than it was in 2004. |
| C．In USA, the demand for oil in 2010 will be as high as it was in 2004. |
| D．In USA, the demand for oil in 2010 will be as low as it was in 2004. |

Sitting in a dark movie theater with your friends and a tub of
buttery popcorn sounds like a perfect way to spend a Saturday night
—and it could be, if you are willing to share your popcorn with the
entire row of moviegoers around you.
A review of the nutritional contents of movie-theater popcorn reveals
an alarming amount of fat, salt and calories in even the smallest sizes.
The study, mad by Dr. Nestle from the Center for Science in the Public
Interest, checked popcorn from three movie theater chains and detailed
The contents of all parts offered.
A large tub of popcorn at Regal Cinemas, for example, holds 20 cups of popcorn and has 1,200 calories, 980 milligrams of sodium（钠）and 60 grams of saturated（饱和）fat.
Not so hungry? The medium size popcorn, which comes in a bag, contains the same amount as the large. And even the small, at 1l cups, delivers 670 calories 550 milligranis of sodium 24 grams of saturated fat.
The findings may surprise those who choose popcorn at the concession stand（货摊） because they believe it is a relatively healthy snack. In fact, plain air-popped popcorn is low in calories and free of saturated fat. Movie theater popcorn, however, is popcorn, however, is popped in oil — often coconut oil, which is 90 percent saturated fat. Add salt to the enormous portions（部分）,and your once-healthy snack turns into a health killer.
Even the “healthiest” sample of popcorn tested, a small size from AMC containing 6 cups of popcorn, had 370 calories, enough to share with a friend, eating one grain at a time to make it last the length of a movie.
The third movie theater chain tested. Cinemark, is slightly better than its competitors because it pops its popcorn in non-hydrogenated canola oil instead of coconut oil. Cinemark’s large tub contains 17 cups of popcorn with 910 calories and 4 grams of saturated fat, as well as up to 1,500 milligrams of sodium — nearly enough for the entire day.
One way to make your popcorn healthier? Ask the theater to pop a portion without salt. Two of the movie theaters that had their popcorn tested said they would oblige such a request. The best way to make your movie snack healthier, however, would be to skip the popcorn — and the concession stand — altogether.
“You could share a tub of popcorn with 10 friends.” Dr. Nestle said. “Or, what a concept, watch the movie without eating anything.”

This is a dangerous world we live in. The numbers of murders goes up every year； people are dying of cancer；more people contract（感染）HIV；more teens are using drugs；etc. You know this because you’ve heard all the statistics on the news. But do you really have an accurate idea what they mean? The numbers are going up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background, statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous.
For example, several years ago a high school student reported dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors（肿瘤）， is found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth. The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really more dangerous? If you think about it, you will realize far fewer people go skiing each year than the number of people who are in danger of a lightening strike. When you think about it, skiing is more dangerous than you might at first think when looking at statistics. If we teenagers are to be left in this world, we had better be able think critically, and form our own views. rather than be easily persuaded by another’s. To be warned is to be prepared.
59．In the first paragraph, what problem does the writer want to warn us?
A. We are now living in a dangerous world.
B. We got a lot of false statistics from the media.
C. There are around us more and more murders, diseases etc.
D. Statistics alone without full background don’t give us an accurate picture of things.
60．Why does the writer use the example in the second paragraph?
A. To show the danger of reporting only part of the information.
B. To argue that high school students are easily persuaded.
C. To prove what is necessary to us might be dangerous.
D. To warn us of the harmful substances（物质）around us.
61．Relative information is often left out because .
A. relative information is not that important
B. the author is trying to show what he or she says is true
C. too much information will make readers feel confused
D. readers are not able to analyze so much information at once
62．What is the main idea of this passage?
A. Some measures must be taken to protect our dangerous world.
B. We should learn to think critically and look at problems from all sides.
C. The growing trend of reporting only half-truths is getting out of control.
D. Teenagers ought to improve their ability of telling right from wrong.
The first thing my host father “warmed” me was that almost everyone in America was a big hugger.
I didn’t understand what he meant until my first party. Whether they were friends or strangers, teenagers or elders, girls or guys, everyone I met gave me a big hug.
However, as time went on, I began to understand America’s hugging culture. When a friend broke up with me, I was sad. When I told my best American friend about it, she said nothing but put her arms around me. Then warmth of the hug was a greater comfort than anything she could have said to me.
One winter day I was walking along the street, shivering（颤抖）. It was then I saw two women, each holding a paper board, on which there were two words：FREE HUGS. Their were red because of the freezing weather and they were jumping up and down to keep themselves warm. “Hi, girl! Do you want a hug?” One of them asked me. I went up and opened my arms. The hug was short but warm and it took some of the coldness of the day away.
After that I became a big hugger myself. One time my host father and I were traveling to another town. When we reached a restaurant where my friend Cindy worked, he stopped the car.
“What’ wrong?” I asked.” “Alice, why don’t you go inside and give Cindy a hug?” He suggested. I went into the restaurant, ran straight up to Cindy, and gave her a hug before she realized what was going on. “That was a big surprise! And you got my day sweetie! ” She told me later.
A hug is a way to communicate love and care. Do you want a hug? My arms are wide open.
