People around the world drink about 180 billion liters of soda a year. That translates to more than 29 liters per person. Experts say the amount of carbonated soft drinks we consume(消费) is growing. New research from the American Heart Association finds that drinking soda, even diet soda, may significantly increase your risk for heart disease. Dr. Ramachandran Vasan led the study. "Drinking just one or more sodas a day may not be as innocuous as people think."
In a large study of 9,000 people, doctors discovered that those who drank one or more sodas a day had a 30% increased risk for obesity(肥胖), a 25% increase in the risk for abnormal(非正常的) blood sugar levels, and a 32% increase in the odds of having low levels of good cholesterol(胆固醇).
All of these factors increase the risk for heart disease. And there was no difference in the results for those who drank diet soda over regular soda. It’s something that surprised even the researchers.
Critics of the study say diet soda may not be the cause of increased risk of heart disease. Connie Diekman is president of the American Dietetic Association. "It does not conclusively say that this will cause that."
In other words, it could be that unhealthy people like soda. Dr. Vasan found those who drink soda generally tend to have greater caloric intake. They eat more saturated fat and trans fats. They also eat less fiber and exercise less. Diet soda drinkers may also share this unhealthy lifestyle. Dr. Vasan agrees that the link he found between heart disease risk and diet soda needs additional study.
【小题1】 What does the underlined word “innocuous” in the first paragraph probably mean?
| A．popular. | B．harmless. | C．effective. | D．risky. |
| A．Only people who overdrink sodas have high risk for heart disease. |
| B．In the study, about one quarter of people have high blood level. |
| C．Both regular and diet sodas can probably increase the risk for heart disease. |
| D．Dr. Vasan is the leader of the American Heart Association. |
| A．All the experts agree with the results of the study. |
| B．Sodas of any kind are certain to increase the risk for heart disease. |
| C．People have expected the results of the research. |
| D．More studies are needed to prove the results. |
| A．By comparing opinions. | B．By giving advice. |
| C．By showing facts. | D．By discussing information. |
【小题1】B

55% of deaths caused by road accidents occur in the first few minutes after a crash. Up to 85% of these deaths could be prevented if first aid were given. The first person on the scene of a road accident will almost certainly be another road user. So as a driver your knowledge of first aid could make a real difference to someone in the event of a road accident.
Assess conditions
·Remain calm. Judge the scene and seriousness of the collision.
·Determine what has happened, how many people and vehicles are involved and the exact location.
·Determine how many casualties(伤亡人数) there are, what is the severity of the injuries, whether anyone is trapped, and whether there is a danger of fire.
Make safe
·Make sure you stay safe and keep off the road. If you need to stop or warn approaching cars, signal to them from the pavement. Wear reflective clothing, use warning triangles, flashing lights and warning lights. Don’t smoke.
·If you are in a car and you come across an accident, first park safely and turn off the engine before you get out to help. Use a triangle warning danger if necessary.
·Consider the safety of others. Don’t move the vehicles, look out for dangers — leaking fuel, chemicals, broken glass or dropping loads — guide uninjured passengers to a place of safety.
Call for help
Dial 999 (or 112) for the emergency services. If there is no phone nearby, send two people in opposite directions to seek help.
Do this as soon as you can or get someone else to do it while you deal with an injured person. You will need to tell the emergency services:
·where you are
·what has happened (describe the accident)
·how many people are injured
·whether they are breathing or bleeding.
The operator will talk you through what to do while you wait for an ambulance to arrive.
Apply emergency first aid
·Remain calm. Reassure the victims.
·Do not allow smoking or offer food or drink to casualties as this could hamper urgent medical treatment.
【小题1】The passage mainly tells us ______.
| A．how to reduce road accident deaths |
| B．how to perform first aid in a road accident |
| C．how to treat the injured people on the scene |
| D．how to protect us from being injured in an accident |
| A．Stand in the middle of the road to stop or warn approaching cars. |
| B．Leave the engine working when he gets out of his car to help. |

Losing weight comes with a lot of health benefits—including making your brain sharper.
Yes, it turns out that overweight may damage cognitive functions (认知功能) such as memory and attention. There have been few studies of overweight and cognitive functioning, possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University.
Growing evidence suggests that being fat is linked to cognitive deficits (缺陷). So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn’t lose weight dropped even further.
The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he’s seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way—eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. “If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well,” he says.
【小题1】There is less research on overweight and cognitive functions because researchers _____.
| A．believe overweight only affects our body |
| B．have focused on ways to sharpen people’s mind |
| C．do not consider overweight a main cause for low cognitive ability |
| D．are clear about the relation between weight and mental functions |
| A．losing weight has little effect on people’s memory |
| B．losing weight can improve people’s mental functions |
| C．overweight people are likely to have psychology problems |
| D．overweight people’s abilities of concentration differ greatly |
| A．Slim people are smarter than overweight people. |
| B．Healthy diet is better than exercise in losing weight. |
| C．Traditional ways of losing weight are better than operation. |
| D．Overweight people will get smarter by taking more exercise. |
| A．Body Weight and Health |
| B．Losing Weight by Operation |
| C．Ways to Improve Mental Functions |
| D．Losing Weight to S harpen Your MindD |

In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don’t stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren’t alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too.
These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked “at what age does youth end?”most of these old people had no answer. Several replied, “Well, perhaps at age 80.”
What accounts for this ability to survive to such old age, and to survive so well？First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr . Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. “Why？What else would I do？”he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel(血管) system stronger.
Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
【小题1】The example of Mr. and Mrs. Mamedov implies that some Caucasians aged 100 to 140 ____.
| A．become weak and hopeless |
| B．are too old to work in the fields |
| C．benefit from physical work |
| D．are still working in the fields |
| A．Retiring from their lives as farmers. |
| B．Having been married for 90 years. |
| C．Hard physical work. |
| D．Having no intentions. |
| A．Clean mountain air. |
| B．Daily hard work. |
| C．Good genes |
| D．Stress and pressure. |
