Many Asian cultures have included frog legs in their diets for centuries -- or at least until they have run out of frogs. But the most famous frog-eaters, and the people who inspired frog-eating in Europe and the United States are the French. By 1977 the French government, so concerned about the scarcity of its native frog, banned commercial hunting of its own amphibians. So the French turned to India and Bangladesh for frogs.As happened in France, American frog-leg fanciers and restaurants also turned increasingly to frozen imports. According to figures collected from government agencies, the United States imported more than million pounds of frozen frog meat each year between 1981 and 1984.So many frozen frog legs were exported from India to Europe and the United States. One of the attractions of Indian frogs, apart from the fact that they have bigger legs than French frogs, was the price. In London, a pound of frozen frog's legs from India cost about ￡, compared with ￡for the French variety.Indian scientists have described as "disastrous" the rate at which frogs are disappearing from the rice fields and wetlands, where they protect crops by devouring damagingsince the India and Bangladesh frog-export bans, Indonesia has become the major exporter of frog legs to the United States and Europe. But no matter what country the legs come from, one thing is usually constant: The legs once belonged to frogs are taken from the wild, not from farms. Frogs are nearly impossible to farm economically in the countries where frogs are commercially harvested from the wild. Exercise A:1.

Can you tell me something about the clubLama: Yes, well we offer a choice of facilities -- gym, sunbed*, sauna* and Jacuzzi* -- that's also from Scandinavia -- as well as our regularfitness classes, that is. And there's a wholefood bar for refreshmentsafterwardsInterviewer: And does it cost a lot I mean, most people think health clubs are really expensive.Lama: Actually our rates are really quite competitive. Since we only started last July, we' ve kept them down to attract customers. It's only ￡30 ayear to join. Then an hour in the gym costs ￡-- the same as halfan hour on the sunbed. Sauna and Jacuzzi are both ~ for half anhour.Interviewer: And is the club doing wellLama: Well, so far, yes, it's doing really well. I had no idea it was going to be such a success, actually. We're both very pleased. The sunbed's sopopular, especially with the over 65s, that we're getting another onein August.Interviewer: What kind of people join the clubLama: We have people of all ages here, from small children to old-age pensioners, though of course the majority, about three-quarters ofour members, are in their 20s and 30s. They come in their lunch hour,to use the gym, mostly, or after work, while the Youngsters comewhen school finishes, around half past three or four. The Jacuzzi'svery popular with the little ones.Interviewer: What about the old-age pensionersLoma: They're usually around in the mornings, when we offer them special reduced rates for the Jacuzzi or sauna, plus sunbed, it's only ￡2,which is half price, actually. It doesn't affect our profits really -- onlyabout 5% of our members are retired.Dialogue 2 skiingSimon: This one shows the view from the top of the mountain.Sally: Oh, it's lovely!Teresa: That's me with the red bobble hat.Sally: Is itTeresa: Yet, it looks kind of silly, doesn't itSally: Yes, it does rather.Teresa: Oh, don't worry. I know it looks ridiculous.Simon: Look. That's our instructor, Werner.Teresa: Yeah, we were in the beginners' class.Sally: Well, everyone has to start somewhere.Simon: Ah, now, this is a good one.Sally: What on earth is thatSimon: Can't you guessSally: Well, it looks like a pile of people. You know, sort of on top of each other. Teresa: It is!Sally: How did that happenSimon: Well, you see we were all pretty hopeless at first. Every day Werner used to take us to the nursery slope* to practise, and to get to the top you had togo up on a ski lift.Teresa: Which wasn't really very easy.Simon: No, and if you fell off you'd start sliding down the slope, right into all the people coming up!Sally- Mmm.Simon: Well, on that day we were all going up on the ski lift, you know, we were just getting used to it, and, you see there was this one woman in our classwho never got the hang of* it. She didn't have any sort of control over herskis and whenever she started sliding, she would sort of stick her ski sticksout in front of her, you know, like swords or something.Teresa: I always tried to avoid her, but on that day I was right behind her on the ski lift* and just as she was getting to the top, she slipped and startedsliding down the slope.Sally: Did she ~Simon: Mmm, with her ski sticks waving around in front of her!Teresa: So of course everyone sort of let go and tried to jump off the ski lift to get out of the way.Simon: And that's how they all ended up in a pile at the bottom of the slope -- it was lucky I had my camera with me.Sally: I bet that woman was popular!Simon oh,yes. everybody's favourite!Exercise A:1. They are looking at some pictures.2. A ski class for beginners.3. Two.Exercise B:Everyday the coach took them to a nursery slope. They got to the top on a ski lift. In their class there was one woman who could never learn how to ski. She couldn't control her skis and whenever she started sliding, she would stick her ski sticks out in front of her. People always tried to avoid her.One day as she was getting to the top, she slipped and started sliding down the slope. Everyone let go and tried to jump off the ski lift to get out of the way and they all ended up in a pile at the bottom of the slope.Passage 2 The Truth about the French!Skiing in France is heaven on Earth for a dedicated skier. There are resorts where you can access skiing terrain that is larger than all the ski resorts in Utah* and Colorado* combined.The larger resorts have an adequate number of restaurants and discos. It is a good idea to eat a good lunch because the mountain restaurants are normally much better than the restaurants in the ski stations.French resorts are mostly government owned and operated. The social system puts a high percentage of money back into the areas. This provides state-of-the-art* lifts, snow making and snow grooming. In general, an intermediate skier who can read a lift map will easily be able to ski all day avoiding lift lines and crowds, even during the busiest season.The French school systems have a staggered* two-week winter vacation period. When the snow is good, nearly all of France migrates to the mountains for this period. The break usually covers the last two weeks of February and the first week of March. The time to absolutely avoid is the "Paris school holiday week" which will always be in the middle period of the vacation time but alternates starting the first or second week of the break.No one has a more undeserved* reputation about his or her character than the French. The French are not generally arrogant and rude. Tree, in large tourist centers there are unpleasant people and if you're looking for or expecting rudeness, you may just provoke* it. Generally the French, especially in the countryside, are as kind as you wish and you will find warmth and acceptance. The most fractious* Frenchman is easily disarmed by a little sincerity*.When greeting someone or saying good-bye, always shake hands. Don't use a firm, pumping handshake, but a quick, slight pressure one. When you enter a room or a sbop you should greet everyone there. If you meet a person you know very well use their first name and kiss both cheeks. Men don't usually kiss unless they are relatives. Good topics of conversation include food, sports, hobbies and where you come from. Topics to avoid are prices, where items were bought, what someone does for a living, income and age. Questions about personal and family life are considered private. Expect to find the French well-informed about the history, culture and politics of othercountries. To gain their respect, be prepared to show some knowledge of the history and politics of France.France is generally a very safe country to visit. Pickpockets, however, are not unheard of. In large cities particularly, take precautions against theft. Always secure your vehicles, leave nothing of value visible and don't carry your wallet in your back pocket. Beware of begging children!Exercise A:When greeting someone or saying good-bye, always shake hands. Don't use a firm, pumping handshake, but a quick, slight pressure one.

Beware of begging childrenPart 3 NewsNews Item 1France's busiest airport will reopen part of a terminal that was not damaged when a segment of the roof collapsed in May, killing four people.The Transport Minister Gilles de Robien said a segment of the three-building 2E terminal at Charles de Gaulle airport would return to service on July 15. In the May 23 disaster, failing glass, steel and masonry* killed four travelers -- two Chinese, one Czech* and one Lebanese*. Three others were injured.A preliminary report by experts said Tuesday that a weakness in the concrete that formed the futuristic terminal's vaulted roof may have contributed to the collapse.Officials are still unsure about what exactly caused it to collapse.Exercise A:This news item is about the new information Of France Charles de Gaulle airport where a segment of the roof collapsed in May.Exercise B:News Item 2An Antonov 26 plane crashed in northwestern Congo shortly after take-off on Saturday, killing all 22 Congolese passengers and the crew.It was not known how many crew members were on the plane when it crashed near the town of Boende, more than 600 km northeast of the capital Kinshasa. The cause of the crash was unknown.A string of accidents this week has underlined the parlous* state of Democratic Republic of Congo's transport infrastructure* after five years of war and decades of misrule.More than 160 people drowned when a ferry sank during a storm on Lake Mai-Ndombe, north east of Kinshasa, on Tuesday.On Saturday, 18 people were killed or injured when a small truck experienced brake trouble and crashed near the eastern town of Goma.Exercise A:This news item is about a strine of accidents this week in Congo.Exercise B:Section three oral workRetellingThere is a street called "The Strand" in Galveston, where hundreds of thousands of touristsvisit today. This street was Mama's stomping* ground as a kid. Before Mama died, we took a streetcar around Galveston to see all the lovely, restored homes. What a great day. She knew morethan the tour guide. As we sat enjoying the sights, Mama said, "Liz, do you know why my nose is a little crooked*" (I thought, "Where did that come from") "No, Mama, you haven't ever mentioned it," I replied."Well," said mother, "one day I followed my brothers to The Strand, and a streetcar ran overme. I put myself flat down between the rails and pushed my face in the ground so hard, I broke mynose! It sure caused a lot of chaos*. People screamed, the police came, and I just crawled out,brushed myself off and went home. The only thing 1 ever noticed different about me was a crookedI just looked at her nose and looked at Mama in utter disbelief!Section Four Supplementary ExercisesBabies and IntelligenceSome people thought babies were not able to learn things until they were five or six months old. Yet doctors in the United States say babies begin learning on their first day of life.Research scientists at the National Institute of Child Health and Development note that babies are strongly influenced by their environment. They say a baby will smile if her mother does something the baby likes. A baby learns to get the best care possible by smiling to please her mother or other caregiver. This is how babies learn to connect and communicate with other humans. This ability to learn exists in a baby even before birth. They say newborn babies can recognize and understand sounds they heard while they were still developing inside their mothers.The Finnish researchers used devices to measures the babies' brain activity. The researchersplayed recordings of spoken sounds for up to one hour while the babies slept.The head of the study believes that babies can learn while asleep because the part of their brains called the cerebral cortex* remains active at night. The cortex is very important for learning. This part of the brain is not active in adults while they sleep.Many experts say the first years of a child's life are important for all later development. AnAmerican study shows how mothers can strongly influence social development and language skills in their children. The study involved more than 1,200 mothers and children. Researchers studied the children from the age of one month to three years. They observed the mothers playing with their children four times during this period.The researchers attempted to measure the sensitivity of the mothers. The women were considered sensitive if they supported their children's activities and did not interfere unnecessarily. They tested the children for thinking and language development when they were three years old.The children of depressed women did not do as well on tests as the children of women who did not suffer from depression. The children of depressed women did poorly on tests of language skills and understanding what they hear. These children also were less cooperative and had more problems dealing with other people.Another study suggests that babies who are bigger at birth generally are more intelligent later in life. It found that the intelligence of a child at seven years of age is directly linked to his or her weight at birth. Study organizers say this is probably because heavier babies received more nutrition* during important periods of brain development before they were born.The study involved almost 3,500 children. Researchers in New York City used traditional tests to measure intelligence. Brothers and sisters were tested so that the effects of birth weight alone could be separated from the effects of diet or other considerations.The researchers found that children with higher birth weights generally didbetter on the intelligence tests. Also, the link between birth weight and intelligence later in life was stronger for boys than for girls.Exercise A:1.

In general, drowsiness is feeling the need to sleep, while fatigue is a lack of energy and motivation. Drowsiness and apathy (a feeling of indifference or not caring about what happens) can be symptoms of fatigue.Fatigue can be a normal and important response to physical exertion, emotional stress, boredom, or lack of sleep. However, it can also be a nonspecific sign of a more serious psychological or , physical disorder. Fatigue that is not relieved by enough sleep, good nutrition, or a low-stress environment should be evaluated by your doctor. Because fatigue is a common complaint, sometimes a potentially serious cause may be overlooked.The pattern of fatigue may help your doctor determine its underlying cause. For example, if you wake up in the morning rested but rapidly develop fatigue with activity, you may have an ongoing pysical condition like an underactive thyroid*. On the other hand, if you wake up with a low level of energy and have fatigue that lasts throughout the day, you may be depressed.Here are some tips for reducing fatigue:Get adequate, regular, and consistent amounts of sleep each night.Eat a healthy, well-balanced diet and drink plenty of water throughout the day.Exercise regularly.Learn better ways to relax. Try yoga* or meditation*.Maintain a reasonable work and personal schedule.Change your stressful circumstances, if possible. For example, switch jobs, take a vacation, and deal directly with problems in a relationship.Take a multivitamin. Talk to your doctor about what you need and what is best for you.Avoid alcohol, nicotine*, and drag use.If you have chronic* pain or depression, treating either often helps address the fatigue. However, some antidepressant* medications may cause or worsen fatigue. Your medication may have to be adjusted to avoid this problem. Do not stop or change any medications without instruction from your doctor.Stimulants* (including caffeine) are not effective treatments for fatigue, and can actually make the problem worse when the drugs are discontinued. Sedatives* also tend to intensify fatigue in the long run.Exercise A:Fatigue is a feeling of weariness, tiredness, or lack of energy. Fatigue is different from drowsiness.
