Butter is bad for you—so is margarine(人造黄油).Coffee raises blood pressure, but may protect against cancer.Alcohol is okay, but only if it's wine.The confusing studies on what is safe to eat and drink are enough to make it impossible for anyone to understand what "good food" is.
Take the margarine-butter debate for example.Studies that linked fat—found mostly in animal products such as meat and butter—with cancer and heart disease sent millions rushing to buy margarine.But then another study found that people who ate a lot of margarine also had high levels of heart disease.For those who have a firm faith in science, this seems to be the end of the world.
But many doctors point out that their advice has never been conflicting.For years, and in various countries, they have recommended eating less fat.
People in western countries such as Britain and the United States get about 40 percent of their calories from fat.Doctors say this should be around 30 or even 25 percent,
"We must try to reduce total fat," said Dr.Robert Richardson of the University of Edinburgh, who has been studying the effects of fat on human health for years.
"We need to go to more such food as bread, in particular brown bread, and more fruit and vegetables."
Fresh produce may not be so safe, either.Last month the British Government advised consumers to peel their pears before eating, while many Americans briefly avoided apples because of fears over an insect killing chemical.
But Dr.Arnold, a British scientist, said any risk of such poisoning would be outweighed by the costs of not eating plant foods.
"On balance, if you were to put both risks against each other, the advice has to be eating as much fruit and vegetable daily as possible," she said.
In general, doctors conclude, variety truly is the best policy."The general advice is pretty much the same advice that doctors have been talking about for a long time—a varied diet, a mixture of foods and not too much of any one," Arnold said.

Divorce is bad for environment
US researchers raised a new theory on Monday: divorce is bad for the environment.
The global trend toward higher divorce rates has created more households with fewer People,
scientists at Michigan State University reported in the Proceedings of the National Academy of
Sciences.
More households means more houses,fuel and water are Heeded for them,the researchers wrote.“Globally,the number of households is increasing much faster than the number ofpeople,”said co-author “Jack” Liu in a telephone interview. “Even in regions with declining populationn, we see substantial increase in the number of households. Divorce is the main reason for reducingthe number of people in a household,” he said.
The average divorced person’s household is about 40 to 50 percent smaller than the average married person’s household, Liu said. But whether there are three or six people in a house ,the amount of fuel needed to heat them is about the same. In the United States, divorced households used 74 billion kilowatt—hours of electricity and 2.850 trillion liters of water in 2005, half of which could have been saved if households had stayed the same size as when they were married.
In the United States and 11 other countries between 1998 and 2002, if divorced households had combined to have the same average household size as married households, there could have been 7.4 million fewer households.
The number of divorced households in those countries ranged from 40,000 in Costa Rica to
almost 16 million in the United States around 2000. The number of rooms per person in divorced households was 33 percent to 95 percent greater than in married households.
“If you really want to get divorced, maybe you can remarry with somebody else, or live together with somebody else you like”, Liu said.
1. In America when the number of households is_________, the number of people in a house is__________.
A. increasing, decreasing B. decreasing, increasing
C. increasing, increasing D. decreasing, decreasing
2. What does the word “substantial” in the third paragraph mean?
A. Great B. Little C. Sudden D. Timely
3. How much electricity would have been saved without so many people getting divorced in America in 2005?
A. 7.4 million kilowatt-hours B. 16 million kilowatt-hours
C. 37 billion kilowatt-hours D. about 30 billion kilowatt-hours
4. The last paragraph is the writer’s_________for people.
A. advice B. encouragement C. demand D. order

高三英语阅读理解中等难度题查看答案及解析
Today we bring you an old tale. It’s the story of the three little pigs and the big bad wolf that blew down a house made of straw and one made of sticks. The only house left standing was the one made of bricks. Now there is new evidence to suggest that houses built with bales of straw can be very strong. They are also very environmental.
Pete Walker is a professor at the University of Bath in Britain. He and a team of researchers there have built a house made out of straw bales and hemp material. During the next twelve months the team will study the effectiveness of these materials in home building. Professor Walker says there are many good reasons for using straw.
Professor Walker: “One of the benefits is it’s a relatively inexpensive renewable material that’s readily available.” He also agrees that straw takes in carbon dioxide as it grows and helps the environment in other ways. So it can be seen as having no harmful effects on the environment.
Professor Walker: “The straw bale walls are relatively thick and so all that straw provides very good thermal insulation. So we make buildings that require very little heating in the winter or indeed very little cooling in the summer. So they require very little additional energy.”
Professor Walker says this reduces home operating expenses. It also reduces the effect on the environment. He says the current interest in straw bale houses is a direct response to the problem of climate change.
David Lanfear owns an eco-friendly home building service in the United States called Bale on Bale Construction. He says he laughed when some friends first told him about houses built of straw. But after doing his own research, he learned that building with straw bales made a lot of sense. He has now helped to build more than ten straw bale houses and says the building material is becoming more widely accepted.
To build the houses, he fills a wood frame with tightly packed bales of straw. Next he coats the walls inside and out with layers of clay plaster. He says the common ideas about straw houses continue, including stories about the threat of fire. Mr. Lanfear says straw bale houses have done well when tested for fire resistance. And he says his builders use the same building methods as traditional builders to keep out rain.
David Lanfear: “We use what we call good shoes and a good hat, and that would be a solid foundation and a really good roof.”
1.What’s David Lanfear’s attitude towards the straw houses at last?
A. Ridiculous. B. Approving.
C. Defensive. D. Unbelievable.
2.What can we infer from the passage?
A. Using straw to build houses is dearer than using bricks.
B. The houses built with bales of straw are stronger than those built with bricks.
C. Straw which is convenient to get is much cheaper than thick bricks.
D. Houses made of bricks are no better than those made of straw.
3.According to the passage, we know that ________________.
A. there is some experience in building the straw houses
B. the house made of straw bales is the same as the traditional one
C. the house made of straw bales is still under research
D. it’s uncertain that the straw house can be very strong

高三英语单项填空中等难度题查看答案及解析
You have signed on for months of hard work.You're far from home.The pay is bad.The food is worse.You find rare comfort in the simple songs that you and your work mates sing.
This is what a sailor's life was like in the 1800s.The songs sung aboard ships were called sea shanties.You have probably heard a shanty or two yourself.Many of these songs have lasted through the years.They can often be found in surprising places today.
Sea Shanties Then ...
Sea shanties were valuable friends to sailors.Some shanties, such as "Blow the Man Down," had lively words and melodies.They broke up the boredom of long trips.Other shanties, including one called "Oh, Shenandoah," had a sadder tone.They helped seafarers express longing and loneliness.Still other shanties, such as "Leave Her, Johnny," let sailors complain about their hard lives.
But the first job of the sea shanty was to help the men work as a team.Ships had sails that were controlled by a system of moving ropes.For many jobs, all of the sailors had to pull on the ropes at once.
When faced with such a job, the shantyman, or song leader, began a tune.The crew joined in on the chorus, and it might have sounded like a playful sing-along.But when the sailors came to a certain beat, they knew it was the signal to pull together with all their might.
Raising or lowering the anchor called for a rhythm with a slow, steady motion.Then, the shantyman would choose a shanty with a slow, steady beat to match the job.Each duty on the sailing ship had its own rhythm and its own kind of song.
...and Sea Shanties Now
Sea shanties have been passed down to us in much the same way as folk stories.Long ago, someone came up with a memorable idea and melody.Others repeated the shanty, often adding changes along the way.
Over time, people saw the sea shanty for the treasure it was.Like any treasure, shanties were collected.Many were written down in books.
Where do the old shanties appear now? Today's musical artists love the fun, beauty, and history of these songs.Many musicians, including Bob Dylan and Harry Belafonte, have their own versions of "Oh, Shenandoah." One group, the Robert Shaw Chorale, recorded a collection of shanties.
In Hollywood, shanties serve as a symbol of the sea.A fisherman sings the shanty "Spanish Ladies" in the film Jaws.The cartoon character Woody Woodpecker whistles "Blow the Man Down" when he finds himself aboard a pirate's ship.
Today, shanties tell us about shipboard life more than one hundred years ago.They help us understand what the working sailor sang and perhaps thought about.
So the next time you're doing a boring task, try making up a tune to go along with it.Time may pass more quickly, and your job may seem easier.Also, you may understand why sailors loved those old songs of the sea.
1.The main purpose of the sea shanty in the 1800s was________.
A.to communicate with passing ships
B.to help sailors work together as a team
C.to allow sailors to complain about the food
D.to give sailors an opportunity to record their music
2.Today, sea shanties are mainly used________.
A.to provide material for musical artists to record
B.to provide a source of music for Hollywood films
C.to help sailors work together aboard modem ships
D.to help people understand the lives of sailors of the past
3.The author uses two subheadings(小标题) within the article in order to_______.
A.compare sea shanties to modem sailing songs
B.describe how popular sea shanties are with musicians
C.compare how sea shanties have been used over the years
D.describe how sea shanties have influenced Hollywood films
4.Which of these topics would most probably be included in this article?
A.The work of sailors today.
B.The cost of sailing ships in the 1800s.
C.Other sailing duties that were made easier by sea shanties.
D.Some music studios where sea shanties are recorded today.
45.5.According to information in the article, a movie director today would most likely use a shanty________.
A.to make a scene about sailors more realistic
B.to give a musician a chance to record the song
C.to make the crew's daily chores pass more quickly
D.to express the loneliness of making a film away from home

We keep reading that TV is bad for you. If this is true, how come the current generation of TV-addicted kids is much smarter than we are? In my home, the only people who can work the remote control are the children.
Perhaps TV does educate you. For example, you learn a useful medical fact: A person who has been shot always has time to speak an incomplete sentence before he dies. “The killer was…” (dies)
But I guess the biggest things we learn from TV can be regarded as “Life Skills”. Bad things only happen on dark and stormy nights. Emotional breakdowns cause people to wander in the heavy rain without umbrellas. And contrary to what scientists say, the crack(霹雳) of lightning and the accompanying flash happen at exactly the same time, wherever you are.
I’ve even acquired useful geographical facts from science-fiction shows: Aliens speak English no matter which planet they come from.
Making use of what we learn from TV can improve our security. Consider these truths. If you are ever attacked by 20 bad guys, don’t worry about being outnumbered. The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all. Bad guys who are completely covered in black clothes always remove their black masks to reveal that they are in fact, aha, women.
TV also teaches us important information about escaping from danger. Watch and learn. (1) If anyone is running after you down a passage, you will find that boxes have been conveniently placed near all the walls you need to jump over. (2) If you are tall and handsome, you can run from any number of armed criminals, and every shot will miss you.
Be warned, however. If your name card says “henchman” (帮凶) and you are part of a group of plain-looking people trying to catch a handsome individual, a single shot will kill you. But don’t be anxious: TV also delivers useful information for bad guys. All cars are inflammable (易燃的) and have amazing shock absorbers that enable them to fly into the air and land without damage — except police cars.
TV even teaches us about TV. Whenever anyone turns on a TV, it shows a news flash about someone they know. They then turn the box off immediately after that news item.
1.By saying “A person who has been shot always has time to speak an incomplete sentence
before he dies” (Paragraph 2), the writer shows his________.
A. humor B. sympathy
C. deep concern D. medical knowledge
2.We can infer from Paragraph 3 that in the real world_______.
A. bad things cause people to break down in the rain
B. bad things never happen on dark and stormy nights
C. people with emotional problems like to walk in the rain without umbrellas
D. the crack of lightning and the accompanying flash don’t happen at the same time
3.On TV what usually happens when a person turns it on?
A. The news shown is always about someone the person knows.
B. The person always turns off the TV when it’s time for news.
C. The program shown is always about the importance of TV.
D. TV always shows news about famous people.
4.What’s the main idea of this passage?
A. Life skills can be learned from TV.
B. TV plays an important role in society.
C. Watching TV makes people more creative.
D. What happens in TV is very different from reality.
