Within fifteen years Britain and other nations should be well on with the building of huge industrial complexes (结合)for the recycling of waste. The word "rubbish" could lose its meaning because everything that goes into the dumps would be made into something useful. Even the most dangerous and un??pleasant wastes would provide energy if nothing else.

The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rub??ber.

Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: first, it will pass through sharp metal bars which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that grounders and rollers break up everything that can be broken. Finally the rubbish will pass under magnets, which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the fi??nal stage.

The first full-scale giant recycling plants are, perhaps, fifteen years away. Indeed, with the growing cost of transpor??ting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long.

1. The main purpose of the passage is ________.

A. to show us a future way of recycling wastes B. to tell the importance of recycling wastes

C. to warn people the danger of some wastes D. to introduce a new recycling plant

2. How many stages are there in the recycling process?

A. 3. B. 4. C. 5. D. 6.

3. What is the main reason for big cities to build their own re??cycling plants?

A. To deal with wastes in a better way. B. It’s a good way to gain profits.

C. It’s more economical than to dump wastes in some dis??tant places.

D. Energy can be got at a lower price.

4. The first full-scale huge recycling plants ________.

A. have been in existence for 15 years B. takes 15 years to build

C. can’t be built until 15 years later D. will remain functioning for 15 years

D
Is a recently discovered hormone the reason why folks who lose weight can’t keep it off?
Like millions of other fat people, at 530 inches high, more than 300 pounds, Carnie Wilson was not just fat. After trying all sort of diets that didn’t work, she has to go to the stomach – bypass surgery (胃部迂回手术), ie, have most of her stomach sewed up, only leaving tiny room to hold several tablespoonfuls at most. Result: she simply couldn’t eat the way she used to. In three years, Wilson is one third of her former weight.
Wilson’s experience is not all that unusual, and while doctors still aren’t exactly sure what is going on, a report in last week’s Journal of Medicine offers an explanation. The loss of appetite in bypass patients may be linked to a recently discovered hormone called ghrelin. Not only that, ghrelin may turn out to be one reason we feel hungry and it’s hare for didters to keep weight off.
Nowadays, researchers are careful to stress only what they know for sure. For the three conclusions, the leading Dr. David of the University of Washington says, “I feel very solid about two of them.” The first is that ghrelin levels in the bloodstream rise significantly before meals and drop afterward. The second conclusion is that ghrelin levels are higher on average in people who have lost weight from dieting.
Dr. David is less sure of the third conclusion, that bypass patients have only a quarter as much ghrelin as most people of normal weight. After all, ghrelin is produced by cells in the stomach. Years ago, leptin, a hormone was found as an appetite suppressant (食物抑制剂). But after years of trying, it had to be given up.
What doctors suspect is that both leptin and ghrelin are part of a complex system of brain and body chemicals that govern weight and appetite. That does not mena pharmaceutical (药物的) weight control is forever out of the question. “In the next ten years, we will be able to develop new drugs to help people lose weight healthily and effectively.”
47．What can we learn about ghrelin according to the passage?
A．After meals ghrelin levels are higher in the bloodstream.
B．People who have lost weight have less ghreilin in their body.
C．Without ghrelin, people are really difficult to lose weight.
D．Ghrelin is something produced by cells in the stomach.
48．What is Dr. David not sure?
A．pharmaceutical weight control is impossible.
       B．There is less ghrelin in the bypass patients.
C．new drugs will be developed in 10 years.
D．ghrelin levels are higher in people on diet.
49．In fact, people’s weight and appetite are controlled by
A．ghrelin and leptin                      B．hormone and medicine
C．brain and body chemicals                  D．stomach and food
50．What can we infer from the passage?
A．People with a lower ghrelin level go hungry easily.
B．Doctors managed to use leption to control the appetite.
C．Doctors are optimistic about how to lose weight healthily.
D．The loss of appetite in bypass aptient is linked to leptin

Is veg food healthier than non-veg food? I feel this is a very common topic that people speak on．Please give me your opinions on this topic．
Rao 12-18-08	So far as veg food is concerned, it is also proved to be a healthy and nutritious diet, but has very few items which can provide us with proteins, but if you see non-veg food like eggs, chicken, and many more, such foods have a large content of proteins in them.
Sai 12-19-08	Man basically is herbivorous（食草的）. If we look at the animal kingdom We can see that all the herbivorous animals have the similar dental（牙齿的） structure, which clearly shows that the human being also ought to be vegetarian by birth. It is only the living conditions that make man carnivorous（食肉的）. The vegetarian foods are easily digestible.
Santos 12-20-08	Non-veg food items are better than veg items. A healthy person requires complete diet and veg+ meat makes the diet complete. The only caution that needs to be taken is not to have non-veg items on a daily basis. Once in a week or couple of weeks will be best.
Krishna 01-03-09	When we eat non-veg, we are all veg by nature. The chicken that we eat feeds on grains, the mutton that we eat feeds on grass, and the fish that we eat feeds on simple plants. So non-veg food by logic（逻辑）is better and suited for hauman beings.
Khan 01-05-09	Non-veg food is equally important in our diet as it helps in many ways, especially fish and other seafood as fish contains omega 3 which makes our immune system（免疫系统）stronger. Do you know that most of the veg food put together does not contain as much omega 3 as fish alone contains!

68．According to Rao, what is the problem with veg food?
A．It damages our immune system.
B．It has few nutrients.
C．It contains too much omega 3.
D．It is lacking in protein.
69．In the opinion of Sai, humans are born vegetarian because humans______.
A．have the same teeth structure as plant-eating animals
B．believe that veg foods are good for their teeth
C．belong to the plant-eating animal family
D．can adapt to the living conditions like plant-eating animals
70．What advice is given by Santos?
A．To have a saily veg+ meat diet.
B．Not to eat non-veg food every day.
C．To eat digestible food every day.
D．Not to eat food without protein.

LONDON (Reuters) Ecotourism is causing a lot of damage to wildlife and may be endangering the survival of the very animals people are flocking to see, according to researchers.

Biologists and conservationists are worried because polar bears, dolphins, penguins and other creatures are getting stressed and losing weight and some are dying.

"Evidence is growing that many animals do not react well to tourists in their backyard，” New Scientist magazine said.

The immediate effects "researchers have noticed are changes in behavior, heart rates. or stress hormone levels but they fear it could get much worse and over the long term “ could endanger the survival of the very wildlife they want to see. ”

Although money produced through ecotourism, which has been growing at about 10-30 percent a year, has major benefits for poor countries and people living in rural areas, the Swiss-based World Conservation Union (IUCN) and some governments fear not all projects are audited（审计） and based on environmentally friendly policies，according to the magazine.

Transmission of disease to wildlife，or small changes to wildlife health through disturbance of daily life or increased stress levels, while not obvious to the casual observer, may translate to lower survival and breeding，” said Philip Seddon , of the University of Otago in Dunedin, New Zealand.

Scientists have noticed that bottleneck dolphins along the northeastern coast of New Zealand become nervously excited when tourist boats arrive. Similar changes in behavior have been observed in polar bears and yellow-eyed penguins in areas visited by colorists are producing smaller babies.

Conservationists are now calling for more research into the effect of ecotourism on animals and say the industry must be developed carefully. They also want studies done before new ecotourism projects are started.

“The animals’ welfare should be very important because without them there will be no ecotourism，” said Rochelle Constantine of the University of Auckland in New Zealand
