Doctors say obesity，also known as severe overweight，is a complex condition.A doctor may advise medical interventions(医疗干预) in addition to changes in behavior.But experts say the more successful weightloss plans include a wellbalanced diet and exercise.
People who want to avoid weight gain have to balance the number of calories they eat with the number of calories they use.To lose weight，you can reduce the number of calories you take in，or increase the number you use，or both.Experts at the National Institutes of Health say to lose weight，a person should do some moderate or intensive physical exercise most days of the week.This could include fast walking，sports or strength training.
A recent study looked at four of the most popular dieting plans in the United States.Researchers at Stanford University studied more than three hundred overweight women，mostly in their thirties or forties.Each woman went on one of the four plans：Atkins，The Zone，Ornish or LEARN.The women attended diet classes and received written information about the food plans.At the end of a year，the women on the Atkins diet had lost the most，more than four and a half kilograms on average.
Christopher Gardner led the study，reported in the Journal of the American Medical Association. He said the Atkins diet may be more successful because of its simple message to lower the intake of sugar.Also，he said the advice to increase protein in the diet leads to more satisfying meals.
But last week，another report suggested that only a small minority of people have longterm success in dieting.Researchers at the University of California found that most dieters regained their lost weight within five years.And often they gained back even more.But those who kept the weight off generally were the ones who exercised.All the following is helpful to lose weight EXCEPT________.
| A．a healthy diet | B．physical exercise |
| C．medical interventions | D．being polite to others |

| A．you eat the same number of calories as the number you use |
| B．you take in less calories than the number you use |
| C．you take in more calories than the number you use |
| D．you take exercise regularly on the weekdays |

| A．there are four popular dieting plans in the USA |
| B．the Atkins diet has the best effect on losing weight |
| C．lots of women attended diet classes every day |
| D．dieting plan is the most important |

We know that cigarette smoking kills． So, producers made electronic cigarettes as a safer smoking choice - safer than tobacco． Although e-cigarettes contain the drug nicotine like cigarettes, they do not use tobacco and you do not light them． They are powered by battery （电池）．
However, if e-cigarettes are so safe, why has the United States Center for Disease Control（CDC） seen an increase in telephone calls about e-cigarette poisonings?
The answer is children． Most of the calls are from people worried about children who have played with the devices, In the period of one month this year, the Center said 215 people called the Center with e-cigarette concerns． More than half of these calls were for children aged five and younger． The devices had made them sick．
Tim McAfee is director of the Center's Office on Smoking and Health, He says the problem is regulation． Meaning, the U．S． federal government does not control e-cigarettes even though they contain liquid nicotine． Mr．McAfee adds that liquid nicotine is a well-known danger． Mr．McAfee explains that nicotine poisoning happens when it gets into the skin, gets into the eyes or is swallowed． It can cause stomach pain or a sense of unbalance． And too much nicotine can kill,
Tim McAfee says e-cigarettes do not create the level of risk to people that tobacco products do．He notes that almost 500,000 Americans die each year from cigarettes． "So, cigarettes are the winner in that contest．" E-cigarettes do not contain hundreds of harmful chemicals that are found in real cigarettes． So, the U．S．Surgeon General Boris D． Lushniak has suggested that e-cigarettes may be a useful tool for adults trying to end their tobacco use．
But McAfee worries that teenagers may think electronic cigarettes are harmless． They could become addicted to the nicotine and then start smoking real cigarettes． In other words, he fears that for young people fake e-cigarettes could be a "gateway" to the real thing．What do the producers think of e-cigarettes?
| A．Dangerous． | B．Expensive． |
| C．Safer． | D．Cheaper． |
Why did the CDC receive so many calls about e-cigarettes?
| A．Parents feared that their children might get poisoned, |
| B．Parents found the device useless in quitting smoking． |
| C．Children swallowed the liquid nicotine from the device． |
| D．Children might get addicted to playing with the device． |
It can be inferred from the passage that ．
A． the CDC wants to develop a better type of e-cigarettes
B． the government is in favor of the use of e-cigarettes
C． Surgeon General Boris D． Lushniak is a heavy smoker
D． smokers most probably can't quit smoking using e-cigarettesWhat is Tim McAfee's opinion about smoking?
| A．Adults should use harmless e-cigarettes． |
| B．Smoking e-cigarettes can make a person sick． |
| C．He claims that regulations should be made to ban smoking． |

The Cuban iguana is a species of lizard（蜥蜴） of the iguana family． It is the largest of the West Indian rock iguanas, one of the most endangered groups of lizards． This species with red eyes and a thick tail is one of the largest lizards in the Caribbean．
The Cuban iguana is primarily herbivorous; 95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species, including the seaside rock bush and various grasses． However, Cuban iguanas occasionally consume animal matter, and individuals have been observed eating the dead flesh of birds, fish and crabs, The researchers wrote that quite a few people on Isla Magueyes could have caused this incident．
The Cuban iguana is distributed throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population booming on Isla Magueyes, Puerto Rico． It is also found on the Cayman Islands of Little Cayman and Cayman Brac, where a separate subspecies occurs． Females guard their nest sites and often nest in sites half destroyed by Cuban crocodiles． To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti （仙人掌）．
In general the species is in decline, more quickly on the mainland than on the outlying islands． One of the reasons for their decline is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests． Although the wild population is in decline, the numbers of iguanas have been sharply increased as a result of captive-breeding（圈养） and other conservation programs．．The underlined word "herbivorous" （Paragraph 2） probably means ．
| A．dangerous | B．gentle |
| C．plant-eating | D．flesh-eating |

My 16-year-old son, Anton, had gone to the local swimming hole． Most of the kids swim there, and there are plenty of rocks for them to use as safe harbors, so I had no fears for his safety．
Still, the firefighter's first words "You need to come up here to the Stillwater River" made me catch my breath, and his follow-up words gave me relief: “ Your son is OK．”
When I got to the river, I immediately saw the firetruck, ambulance and Anton, wrapped with a towel about his shoulders, sitting quietly on a low platform of the fire engine．
I hurried over to him． "You OK?"I asked．
”Yeah," was all he said． But my eyes begged for an explanation, I didn't get it from my son, however, who tends to play his cards close to his vest．
The story was this: A woman was being swept under water． Hearing the cries, Anton and his friend Tyler, without hesitation, swam out to her, and brought her safely to shore．
In an age in which the word "hero" is broadcast with abandon and seemingly applied to anyone who make it through the day, I realized the real thing in my son． The teens are stubborn and self-centred, but that didn't mean they have no desire to do good．
Still shocked by my son's daring, I drove him home． Along the way, I tried to dig out some more information from him - but he had precious little to say． The only words he said were,
”What's for supper?"
I spent some time alone that evening, thinking about the tragedy that might have been． The next morning, when Anton got up, I half expected him to tell me the story． But all he did was toast some bread, pull himself together, and head for the door to start a new day． Watching from the window,1 was reminded that still water often runs deep．Why did the mother allow her son to swim there?
| A．He was an excellent swimmer． |
| B．The water of the river is shallow． |
| C．He was old enough to swim． |
| D．The rocks can be of help if there's danger． |
The underlined part "who tends to play his cards close to his vest" probably means
| A．Anton is a boy fond of swimming with other kids |
| B．Anton is unwilling to tell others what he thinks |
| C．Anton always has a desire to help others |
| D．Anton seldom changes his mind |
In the mother's eyes, what her son did was
| A．dangerous but interesting |
| B．unexpected and courageous |
| C．meaningful but difficult |
| D．awful and absurd |
What might be the best title for the passage?
| A．My Son, My Hero | B．Anton, A Silent Boy |
| C．A Good Deed | D．A Proud Mother |
