It is very important for people to drink water in our everyday life. Many people believe they are supposed to drink eight glasses of water a day, or about two liters. Why? Because that is what they have been told all their life. But a recent report offers some different advice. Experts say people should obey their bodies; they should drink as much water as they feel like drinking. The report says most healthy people meet their daily needs for liquid by letting thirst be their guide. The report is from the Institute of Medicine, part of the National Academies. The report contains some general suggestions. The experts say women should get about 2.7 liters of water daily. Men should get about 3.7 liters. But wait——in each case, that is more than eight glasses.
There is one important difference. The report does not tell people how many glasses of water to drink. In fact, the experts say it may be impossible to know how many glasses are needed to meet these guidelines. This is because the daily water requirement can include the water content in foods. People do not get water only by forcing themselves to drink a set number of glasses per day. People also drink fruit juices and sodas and milk. They drink coffee and tea. These all contain water. Yet some also contain caffeine. This causes the body to expel(排出)more water. But the writers of the report say this does not mean the body loses too much water.
As you might expect, the Institute of Medicine says people need to drink more water when they are physically active. The same is true of those who live in hot climates. Depending on heat and activity, people could need two times as much water as others do. All this, however, does not answer one question. No one seems sure why people have the idea that good health requires eight glasses of water daily.
It may have started with a misunderstanding. In 1945, the National Academy of Sciences published some guidelines. Its Food and Nutrition Board(营养膳食) said a good amount of water for most adults was 2.5 liters daily. This was based on an average of one milliliter(毫升)for each calorie of food eaten. But that was only part of what the board said. It also said that most of this amount is contained in prepared foods.
1.In experts’ opinion, every day a person should drink ____.
A. as much water as he can B. more than eight glasses of water
C. according to actual need for his body D. when he comes in sight of water
2.What is mainly described in the second paragraph?
A. People know about the daily water requirement.
B. People need water instead of all kinds of drink.
C. People get daily water not only from drinking.
D. People drink all kinds of drink every day.
3.Who might drink less water according to the third paragraph?
4.The main purpose of writing the texts is to _______.
A. make a good suggestion of drinking daily B. make clear the requirements to drink daily
C. tell the importance of drinking water daily D. figure out a good amount of water daily

Since the gene, called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging, immunity(免疫)and resistance in humans, the scientists said.
“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity,” said Robin May of the University of Birmingham, who led the study.
Populations across the world are aging at a surprising pace, bringing potentially big challenges for health and social care systems. A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays. Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend.
“What we have found is that things like resistance and aging tend to go hand in hand,” May said in an interview.
May’s team compared longevity, stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAF-16 in each of the four species, and found that they were all quite distinct.
May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes, which scientists believe play a role in the aging process.
“The fact that subtle（微妙的）differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution,” May said.
1.In which section may the text appear in a newspaper?
A. Education. B. Science. C. Entertainment. D. Culture.
2.What can we know from the third paragraph?
A. New ways have been found to affect aging. B. Babies in the rich world will all live longer.

3.From the text we know that DAF-16._________
A. is a gene that is only found in worms B. can make people live longer
C. has an effect on aging and immunity D. has been quite familiar to scientists
4.What can be the best title of the passage?
A. Scientists Find Gene Linked to Aging B. Population Aging Faster than Expected

“Up until about five years ago, students at this school could have worn anything they wanted on Halloween,” said Rosemarie Nielson, a sixth-grade teacher at St. Theresa School, a Roman Catholic elementary school in the Pelham Bay section of the Bronx where there is a prohibition on toy weapons.
“When you consider all the horrific things that have happened in recent years, including 9/11, I can’t blame any school for wanting to stay away from anything that might promote violence,” Ms. Nielson s aid.
Mary Ellen Manniello, whose daughter, Courtney, 9, is a fourth grader at St. Gabriel School, a Roman Catholic elementary school in the Riverdale section of the Bronx, said she understood why officials had banned weapons with costumes. “They’re learning more about guns from issues in the street than educational issues.”
This year, the school has gone one step further and is prohibiting all costumes at its Halloween festivities. Ms. Manniello said it had become “a chaotic scene,” with parents helping their children change into their costumes at school.
Some parents said the no-weapons policy for Halloween costumes went too far and denied children a chance to express themselves.
“Halloween has always been the one day when it was acceptable for our children to be dressed like somebody they are not, like a cowboy or a pirate or a person from outer space, and now we’re taking that away from them,” said Laura Santoro, a nurse from New Milford, Conn., whose 7-year-old son, Johnny, is a second grader at Northville Elementary School there.
Ms. Santoro said that her son would dress as Capt. Jack Sparrow, the character played by Johnny Depp in the “Pirates of the Caribbean” movies, at the school’s Halloween party, but that he would not be allowed to take a sword — part of a policy that caught her by surprise last Halloween.
“I sent my son to school last year dressed as a special force Power Ranger, and he was told that he couldn’t take along his red laser blaster, which really surprised me, because the laser is red and made of plastic and lights up, and it could never, ever be mistaken for a real gun,” Ms. Santoro said. “I mean, come on, the whole thing is getting really sad.”
1.What do you think is the writer’s purpose of writing the passage?
A. To introduce to the public the no-weapons policy for Halloween costumes.
B. To state parents’ attitudes towards the no-weapons policy for Halloween costumes.
C. To tell the public that children should bring any weapons for Halloween costumes.
D. To analyze the fact that the no-weapons policy for Halloween costumes goes too far.
2.According to the passage, some parents understand the no-weapon policy for Halloween costumes because ____________.
A. schools should take a cautious approach to Halloween to prevent violence.
B. children are buying real guns in the street and there is always violence now.
C. those parents like to help their children change into their costumes at school.
D. children are learning more about guns from educational issues.
3.Which of the following is probably right according to the passage?
A. Children could bring any weapons into school five or six years ago.
B. The parents surveyed are those whose children are in elementary schools.
C. Guns are necessary on Halloween for children to express themselves.
D. Jack Sparrow is an actor who at one time acted as a pirate in a movie.
4.What do the underlined words “laser blaster” in the last paragraph refer to?
A. A kind of costume. B. A real gun.
C. A toy weapon. D. A kind of plastic.

Here is what I have been told of the matter.
In the spring of 1842, Marguerite was so weak, so different in her looks, that the doctors had ordered her to take the waters. She therefore set out for Bagneres.
Among the other sufferers there, was the Duke's daughter who not only had the same complaint but a face so like Marguerite's that they could have been taken for sisters. The fact was that the young Duchess was in the third stage of consumption and, only days after Marguerite's arrival, she passed away.
One morning the Duke, who had remained at Bagneres caught sight of Marguerite as she turned a corner of a gravel walk. It seemed as though he was seeing the spirit of his dead child and, going up to her, he took both her hands, embraced her tearfully and, without asking who she was, begged permission to call on her and to love in her person the living image of his dead daughter.
Marguerite, alone at Bagneres with her maid, and in any case having nothing to lose by compromising herself, granted the Duke what he asked.
Now there were a number of people at Bagneres who knew her, and they made a point of calling on the Duke to inform him of Marguerite's true situation. It was a terrible blow for the old man, for any resemblance with his daughter stopped there. But it was too late. The young woman had become an emotional necessity, his only excuse and his sole reason for living.
He did not criticize her, he had no right to, but he did ask her if she felt that she could change her way of life, and, in exchange for this sacrifice, he would offer all the compensations she could want. She agreed.
It should be said that at this point Marguerite, who was by nature somewhat highly strung(excited and nervous), was seriously ill. Her past appeared to her to be one of the major causes of her illness, and a kind of superstition(迷信) led her to hope that God would allow her to keep her beauty and her health in exchange for her regret and shame.
And indeed the waters, the walks, healthy fatigue and sleep had almost restored her fully by the end of that summer.
The Duke accompanied Marguerite to Paris, where he continued to call on her as at Bagneres.
This connection, of which the true origin and true motive were known to no one, gave rise here to a great deal of talk, since the Duke, known till now as an enormously wealthy man, now began to acquire a name for the prodigality(挥霍).
1.Why did the Duke take Marguerite’s both hands when he saw her?
A. His daughter and Marguerite were once good friends. B. Marguerite is his daughter’s spirit.
C. Marguerite resembles his daughter. D. They haven’t seen each other for long.
2.What’s the right order of the events?
a. The Duke accompanied Marguerite to Paris.
b. Marguerite set out for Bagneres.
c. The Duke took Marguerite as his daughter.
d. The daughter of the Duke passed away.
e. Marguerite took a gravel walk
A. e-c-b-d-a B. c-d-e-b-a C. b-d-e-c-a D. d-a-c-b-e
3.From the passage we can guess that Marguerite _______.
A. doesn’t believe in God B. was once a woman without a good fame
C. was strange to all the people in Bagners
D. kept her own way of life while living with the Duke
4.According to the passage, Marguerite went to Bagners _______.
A. just for a gravel walk B. to find her sister
C. to visit the Duke D. for treatment
