The Dangers of Dieting
Thanks to our modern lifestyle, with more and more time spent sitting down in front of computers than ever before, the number of overweight people is at a new high. As people crazily search for a solution to this problem, they often try some of the popular fad(时尚) diets being offered. Many people see fad diets as harmless ways of losing weight, and they are grateful to have them. Unfortunately, not only don’t fad diets usually do the trick, but they can actually be dangerous for your health.
Although permanent weight loss is the goal, few are able to achieve it. Experts estimate that 95 percent of dieters return to their starting weight, or even add weight. While the irresponsible or unwise use of fad diets can bring some initial results, long-term results are very rare.
Nonetheless, people who are bored with the difficulties of changing their eating habits often turn to fad diets. Rather than being moderate, fad diets involve extreme dietary changes. They advise eating only one type of food, or they prohibit other types of foods entirely. This results in a situation where a person’s body doesn’t get all the vitamins and other things that it needs to stay healthy.
One popular fad diet recommends eating lots of meat and animal products, while nearly eliminating carbohydrates（碳水化合物）. A scientific study from Britain found that this diet is very high in fat. According to the study, the increase of damaging fats in the blood can lead to heart disease and, in extreme cases, kidney failure. Furthermore, diets that are too low in carbohydrates can cause the body to use its own muscle for energy. The less muscle you have, the less food you use up, and the result is slower weight loss.
Veteran(老兵) dieters may well ask at this point, “What is the ideal diet?” Well, to some extent, it depends on the individual. A United States government agency has determined that to change your eating habits requires changing your psychology of eating, and everyone has a different psychology. That being said, the British study quoted above recommends a diet that is high in carbohydrates and high in fiber, with portions of fatty foods kept low. According to the study, such a diet is the best for people who want to stay healthy, lose weight, and keep that weight off. And, any dieting program is best undertaken with a doctor’s supervision.After losing weight by dieting, what usually happens to people?
| A．They have kidney failure. |
| B．They gain the weight back again. |

I went to the Chinatown market in London last Sunday. The first thing I did was to go to one of the Chinese green grocers’ shops. As soon as I entered the shop, I smelt mixtures of Chinese spices and saw the new season’s fruits. My son wanted a bag of sweets, so we popped into the shop next door which sells many kinds of candy.
There’s a lot of noise in the Chinatown market and you will see many tourists too. There are a lot of cars and trucks that never stop beeping. While people are loading and unloading their goods, most of them have their cars and trucks parked in the middle of the road. This causes great inconvenience for other drivers. Can you imagine that?
After we had done all our shopping, my son and I went to a restaurant for lunch. We enjoyed our meal very much. But the shopping made us both very tired at the end. We headed down the road to catch our bus home. My son and I enjoyed riding in the bus. We also enjoyed looking at different buildings and people walking by dressed in fancy outfits. Although Chinatown can be a busy place to shop, I do enjoy going there now and then. I can buy some of my necessities, and I can also look and browse around the other shops and department stores where I can indulge (使沉迷) myself with some nice things. Chinatown is located in the heart of central London where you can find tons of shops and other places to amuse you. And for me, I certainly don’t mind going back there again soon.The underlined words “popped into” most probably could be replaced by “_____”.
| A．broke into | B．rushed into | C．pushed into | D．walked into |
The author probably didn’t go to a ______.
| A．restaurant | B．grocery |

Playing with toy blocks (积木) may lead to improved language development in young children, a new study reported.
Early childhood is an important period in the development of young minds. The newborn brain grows three times in size between birth and age 2. Scientists have said that certain activities during this important period may promote (促进) healthy development while others may hold it back, and development of memory and language may especially be helped by imaginative play.
After six months, language scores among half of the 175 children aged 1-1/2 to 2-1/2 who were sent plastic blocks were 15 percent higher than a matched group that did not receive the free blocks, according to the study by researchers at the University of Washington in Seattle.
Parents were given ideas about how to help their children play with the blocks, then were told 
to keep diaries of their children’s activities over four days. Finally, all the parents filled out questionnaires that judged their children’s vocabulary, grammar, and other language abilities. Study author Dimitri Christakis said unstructured play with blocks motivated children’s thinking, memory and physical skills at a time when a child’s brain is growing rapidly. “They are the foundation of thought and language,” he wrote of the skills learned from building blocks. “Older children begin to make up stories for these objects .”
Such play may also take the place of less helpful activities such as watching TV, he said, adding parents ought to have doubts about some toy-makers’ words. “An increasing number of media-based products are making ungrounded (无根据的) claims that they can make children smarter, more literate, and more musical,” Christakis said.What can we learn from the second paragraph?
| A．Parents should allow their children to play as long as they want. |
| B．The brains of kids develop very quickly before they are two years old. |
| C．Playing blocks can help children do well in sports at school. |
| D．Activities, like imaginative play, may delay the development of the brain. |
According to the study, about ________ children’s language scores were 15 percent higher than those of children who didn’t play with blocks.
| A．87 | B．55 | C．23 | D．157 |
Building blocks helps kids gain language skills because _________.
| A．young children always talk to themselves while building blocks |
| B．their parents can teach them when they are playing with blocks |
| C．their parents are given ideas on how to develop their brains |
| D．it can help them improve thinking, memory and physical skills |
The aim of the passage is probably to _______.
| A．raise the present level of children’s language ability |
| B．encourage parents to let their babies play with blocks |
| C．improve parents’ knowledge of raising children |
| D．encourage makers of blocks to develop more toys |
We can infer from what Mr Christakis said that _____.
| A．television will be definitely replaced by blocks |
| B．the market will be full of media-based toys |
| C．we can’t always believe what toy makers say |
| D．toy makers care about kids’ development very much |
Today, innovations(创新) to make our lives more eco-friendly can be found everywhere. There are energy-efficient automobiles, eco-friendly light bulbs, and clothes made by fashion designers using sustainable(可持续的) environmental practices. Industries around the world have also begun to take a serious look at how their operations affect the local and global environment.

Please help! I live in Germany with my wife and three kids. My parents live in the UK. I want my kids to have as much contact with their grandparents as possible. The kids all use e-mail, Skype and SMS but my parents won’t. I’ve bought them a laptop, paid for broadband, given them both mobile phones and a digital camera, but they won’t use them. My parents say they hate computers and new technology. What can I do with these “technophobes”?
Daniel, Buremburg, Germany
Actually, the original technophobes were the Luddites, a group of cloth workers in 19th century Britain during the Industrial Revolution. The Luddite cloth workers, who traditionally made cloth by hand, were worried that machines were going to take away their jobs and way of life. These machines could make cloth much faster and cheaper than humans. In 1811 and 1812 the Luddites destroyed the machines that they hated so much, but the British government supported th
e factory owners. Many Luddites were arrested. Charlotte Bronte’s novel Shirley will tell your parents all about it.
Laura, Valencia, Spain
Laura makes some
interesting points, I think. Technophobes has been a common theme in science fiction. Frankenstein, one of the first science fiction, is a warning of what could happen if humans began to experiment with human life.

One thing you could try is to find hardware that is designed for older people to use. An example is the mob
iles made by the US company, Jitterbug. Instead of icons and menus the Jitterbu
g phones ask users simple “yes/no” questions and have larger keypads. The company realized that there are potentially 100 million older users in the US alone.

American author Mark Twain once noted that “life would be surely happier if we could only be born at the age of 80 and gradually approach 18.” Twain’s words were only one of many complaints about aging. The ancient Greek poet Homer called old age “hateful”, and William Shakespeare termed it “terrible winter”.
Alexander the Great, who conquered most of the known world before he died around 323 B.C., may have been looking for a river that healed the ravages of age. During the 12th century A.D., a king called Prester John ruled a land that had a river of gold and a fountain of youth.
But the name linked most closely to the search for a fountain of youth is 16th-century Spanish explorer Juan Ponce de Leon. He thought it would be found in Florida. In St. Augustine, the oldest city in the U.S., there’s a tourist attraction. It is said to be the fountain of youth that Ponce de Leon discovered soon after he arrived in what is now Florida in 1513. However, elderly visitors who drink the spring’s water don’t turn into teenagers.
But the tale of the search for a fountain of youth is so appealing(有吸引力的) that it survives anyway, says Ryan K. Smith, a professor of history. “People are more attracted by the story of looking and not finding than they are by the idea that the fountain might be out there somewhere.”
Still, a few grains of truth have helped to support the story. Kathleen Deagan, a professor of archaeology, says a graveyard and the remains of a Spanish mission dating back to St. Augustine’s founding in 1565 have been discovered near the so-called fountain of youth. Michelle Reyna, a spokesperson for the Fountain of Youth Arc
haeological Park in St. Augustine, says the fountain has been a tourist attraction since at least 1901 and may have been attracting visitors since 1860. According to the passage, who searched for a fountain of youth?
| A．Ponce de Leon | B．William Shakespeare. | C．Kathleen Deagan | D．Michelle Reyna |
What does the underlined word “ravages” in the second paragraph probably mean?
| A．Growth. | B．Limits. | C．Damages. | D．Benefits. |
What is the attitude of people towards the fountain of youth?
| A．People find much pleasure in looking for it. |
| B．People believe the existence of it somewhere. |
| C．People have no interest in searching for it. |
| D．People consider the idea of the fountain of youth absurd(荒谬的). |
The passage mainly tells us _____.
| A．how the fountain of youth came into being |
| B．why some famous people hate becoming old |
| C．how to remain young forever |
| D．whether the fountain of youth exists |
Which of the following is TRUE according to the passage?
| A．The underlined words “the story” refers to Alexander the Great ruling a land that had a river of gold and a fountain of youth. |
| B．Augustine, which is the oldest city in the U.S, lies in Florida. |
| C．Some elderly visitors find themselves younger after drinking the water from the fountain of youth. |
| D．Kathleen Deagan is the spokesperson for the Fountain of Youth Archaeological Park. |
