I've been eating a high-Fat,carbohydrate(碳水化合物)-restricted diet for almost 20 years,since I started as an experiment when investigating nutrition research for the journal Science. I find if s easy for me to keep a healthy weight when I eat this way. But even after two decades, the feeling of being on the edge of a slippery slope is ever- present.

Researchers are generally divided on why we often fail to stay on diets and what causes obesity. The conventional thinking, held by the large proportion of the many researchers, is that obesity is an " energy balance" disorder,and so the treatment is to consume less energy ((fewer calories) ) and spend more. When we fail to keep this prescription, it suggests that we simply lack will power.

The minority position in this field—one that Dr. Ludwig holds, as do I after years of reporting—is that obesity is actually a hormondal(激素的)regulatory disorder, and the hormone that controls this process is insulin (胰岛 素).It signals fat cells to gather fat,while telling the other cells in our body to bum carbohydrates for fuel. By this thinking these carbohydrates, particularly grains, known as high GI carbs, as well as sugars are likely to make you fat.

"Raise insulin levels even a little" , says Dr. Robert Lustig, a professor at the University of California, San Francisco,"and the body switches over from burning fat for fuel to burning carbohydrates. Once people who are 'carboholics,' get their insulin levels down, they become less carboholic. And if they start eating carbs, they go right back to where they were before. " Researchers like Dr. Ludwig and Dr. Lustig believe that a person can minimize these carbohydrate desire by eating lots of healthful fats instead.

Finally, any successful diet is by definition a long-term commitment. If we buy into the logic of carb -restricted diets, then it implies acceptance of a lifetime restriction.

1.What does the author feel like doing according to the last sentence of the first paragraph?

A.Keeping a healthy weight. B.Sticking to a good habit.

C.Stopping nutrition research. D.Breaking a diet

2.What does the author think lead to obesity?

A.Lack of exercise. B.Taking in too many carbs.

C.Lack of will power. D.Taking in too much calorie.

3.According to the text,what would Dr. Lustig advise carbholics to do?

A.Reduce carb intake to the least. B.Consult doctors immediately.

C.Consume as much fat as possible. D.Work out regularly.

4.What is the best title of the text?

A.Why is cutting carbs so tough? B.What does a healthy diet consist of?

C.Who are to believe,the majority or the minority? D.How can we lose weight?

Rabbits are easy to raise. They are clean and quiet. They don’t need a lot of room. And it costs a small amount of money to feed them, but you can get a big return.

One male and two females will produce as many as fifty more rabbits in a year. That is enough to provide enough meat for a family. Rabbit meat is high in protein and low in fat.

You don’t have to be a farmer to raise rabbits. You can raise them in the city.

Rabbit houses are easy to make with wood and wire. They don’t have to be very big. But each rabbit must have its own little room in the house. This is very important. Each room should be about 75 centimeters wide, 60 centimeters high and one meter deep.

Fencing is used for the sides and floor of the rabbit house. The holes in the wire fencing should be about one centimeter square. Waste from the animals will drop through the holes. This keeps the rabbit house clean and dry.

Rabbits need a lot of fresh air and sunlight. Cover the sides of the rabbit house only to protect it from rain.

Rabbits eat mostly grass and leaves. Hang feeding containers on the outside of the house to let the rabbits eat whenever they want. They simply pull the grass and leaves through the holes in the fence.

Each room should have fresh water. The water containers should be heavy so the rabbit cannot turn them over. Or you can tie the containers to the fence.

One month after mating(交配), female rabbits give birth to about eight babies. In two months, a baby rabbit should weigh about two kilograms. This is big enough to make a meal for a small family.

Rabbits are also valuable for their fur. It takes time, skill and money to prepare the fur and skin for use. If you have only a few rabbits, it probably would be best to let a tanner(制革工) prepare the fur for you. Skill is also needed to remove the fur from the rabbit.

But rabbits do not have to be dead to be valuable. Many people enjoy keeping rabbits as friendly pets. And rabbit waste makes an excellent fertilizer(肥料). It can be mixed directly into the soil to improve the growth of vegetables, trees, and flowering plants.

1.The text is written mainly_______.

A. to explain why rabbits are clean and quiet   B. to let people know more about rabbits

C. to tell readers how to raise rabbits         D. to introduce a small friendly animal pet

2.What is important if you raise rabbits?

A. Holes are needed for waste to drop through.

B. Each rabbit must be given a separate room.

C. Each room must have clean water every day.

D. Feeding containers are hung on the fence.

3.Why should the holes in the wire fence be about one centimeter square?

A. Because the holes let in sunlight.     B. Because rabbits like these holes.

C. Because rabbits get food from them.

D. Because waste of rabbits drops through the holes.

4.What does the underlined sentence in the last paragraph mean?

A. You don’t have to kill rabbits to make more money.

B. Rabbits cannot be sold to make money when they are alive.

C. Rabbits are more valuable when they are alive.

D. Rabbits have to be killed to be more valuable.

Scientists have found what look like caves on Mars(火星),and say they could be protecting life from the planet’s terrible environment.

Images of the Mars caves from Northern

Arizona University

The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA’s Mars Odyssey orbiter.Each as large as a football field,they may be openings into natural caves below the Martian surface.

“If there is life on Mars,there is a good chance you’d find it in caves,”said Jut Wynne,one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program.

Jonathan Clarke,a geologist with the Mars Society of Australia,yesterday described the discovery as exciting.

One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm,suggesting hot air trapped during the day is flowing out.

“I said:‘Wow,that’s a cave’,”Dr.Clarke said excitedly.“People have been looking for these for a long time;now we have found them.”

He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold,radiation-soaked(充满辐射的),dry surface.

“Tiny drops of water could collect inside,”he said.“If there are gases coming out,they could provide energy for a whole range of bacteria.A cave is also a protection from radiation;the surface of Mars is exposed to high levels of space radiation.”

The caves probably formed when tube-shaped lava flows(管状岩浆流) spread across the planet long ago.The outside of the tubes cooled,forming solid walls,while something hotter inside allowed the remaining lava to flow out,forming caves.

1.What does the passage mainly talk about?

A.How the caves were formed on Mars.

B.How scientists found these caves on Mars.

C.Caves on Mars may be full of hot air or a sign of life.

D.Scientists have completely recognized the surface of Mars.

2.We can learn from the passage that _______.

A.water has already been found on Mars

B.the scientists found all the caves at night

C.it is certain that there is life in these caves

D.the surface of Mars is bitterly cold,radiation-soaked and dry

3.According to the passage,Dr.Clarke was so excited because _______.

A.such caves could provide energy for life

B.they had finally found the caves on Mars

C.such caves would be perfect places to hunt for life

D.scientists had long been looking for these caves

4.Necessary conditions for life on Mars mentioned in the passage may include _______.

A.lava and energy

B.water and radiation from space

C.gases and lava

D.water and protection from radiation
