The sea has always interested man. From it he can get food, minerals, and treasure.     But he could not go far beneath its surface.
    However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.
  A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases.     He can carry a tank of air on his back and breathe through a nose and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea.   
When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜水夫病). The bends can cause a diver to double up in pain.   

A.His body is under great pressure.
B.Scientists are trying to find more about the sea.
C.For thousands of years, he could sail on it.
D.They can even kill him.

E. He can wear a diving suit and have air pumped to him from above.
F. The water pressure can cause a diver to breathe with difficulty.
G. Man wants to explore deep into the sea.

I’m glad to find this comment which has some sort of support in this quest(寻求)I have to eat raw(未煮熟的)foods. I’m an unhealthy 49 years old and have come to the conclusion that it’s now or never, so I am taking a dive into the raw eating lifestyle.
I have to cook for my family and prepare what they want to eat. I’m trying to plan out this better so I have some of these unusual foods ready for myself.
I’ve read several books written by Ann Wigmore and like her approach to the living foods.
Last week I attempted fasting(禁食)and failed. I lasted five days by having carrots, spinach, apples and other vegetarian diets I could get my hands on. I was doing fine until I drank some coffee. I kind of proved it in my mind to have the coffee but it only made me excited and then I couldn’t sleep well and felt hungry and weak. So I stopped and went back to the old way of eating with the family.
This week I started to make a drink called rejuvelac made of sprouted wheat(芽麦). This is fairly new to do for me and the drink smelled sort of musty(发霉的)and tasted kind of like a musty lemon. The kids tasted it and almost threw up but surprisingly it tasted good to me. It is supposed to help in digestion(消化).
I’ve made some attempts to grow wheat grass. I think I have figured that out as long as I keep it away from birds and our horses. I have two habits to get rid of, drinking coffee and smoking. I quit smoking last month but something happened, so I started up again. I’m very frustrated(受挫的) with the smoking and really have a desire to quit for good. Anyhow I will keep this updated on my progress.

Many children first learn the value of money by receiving an allowance. Parents often give their children an amount of money that they may spend as they wish. The purpose is to let the children learn from experience at an early age when financial mistakes are not very costly.
A child may receive an allowance each week or each month. The amount is not so important. But parents should make clear what the child is expected to pay for with the money.
At first, young children may spend all of their allowance soon after they receive it. If they do this, they will learn the hard way that spending must be done within a budget. Parents should not offer more money until the next allowance is to be given.
Older children may be responsible enough to budget larger costs like those for clothing. The object is to show young people that a budget demands choices between spending and saving.
Many people who have written on the subject say it is not a good idea to pay your child for work around the home. These jobs are a normal part of family life. Paying children to do extra work around the home, however, can be useful. It can even provide an understanding of how a business works.
Allowances give children a chance to experience three things they can do with money. They can share it in the form of gifts or giving it to organizations. They can spend it by buying things they want. Or they can save it.
Saving helps children understand that costly goals require sacrifice: you have to cut costs and plan for the future. Requiring children to save part of their allowance can also open the door to future saving and investing. Many banks offer free savings accounts for young people with small amounts of money.
The functions of allowances given to children are the following EXCEPT ______.

A.they can save more money for their future business
B.they can give them to charities
C.they may spend them on what they like
D.they can learn to deal with money

The underlined word "sacrifice" in the last paragraph means "_____".

A.牺牲 B.计划 C.选择 D.放弃

A.Children are advised to buy anything they wish to with the allowance.
B.Parents should offer children more money if they spend all of their allowance soon after they get it.

A Tchaikovsky concerto(协奏曲)is what made Romel Joseph fall in love with the violin.
He learned how to play in Haiti, where he was born, but a Fulbright scholarship brought him to the United States, and he finally earned a master’s degree, reports CBS News reporter Katie Couric. Music had changed his life. He wanted to do the same for the children of Haiti.
Joseph built a school in Port-au-Prince nearly 20 years ago. He was on the third floor when suddenly “It was like boom boom boom and everything just opened,” Joseph said. “And the next thing I knew I was on the ground.”
Blind since birth, Joseph tried to feel his way out, but was pinned(夹)beneath heavy concrete(混凝土). He remained trapped for 18 hours. He prays that his new wife, seven months pregnant(怀孕的), will be found.
He is now being treated at Miami’s Jackson Memorial Hospital for two injured legs and an arm.
Joseph wonders if he’ll ever play the violin again. He can feel sensation(知觉)in his fingertips. He said, “If you were to give me a violin and if I didn’t have to fold the fingers, I would be able to play.”
Joseph’s daughter Victoria spent three terrifying days unsure of her father’s fate. For her, having him home is the sweetest music.
“Can you imagine your dad not being able to play the violin?” Couric asked.
“No, I can’t,” Victoria Joseph said. “But I will love him all the same if he can’t.”
Romel doesn’t know how many of his 300 students died in the quake. As he waits for news about his wife, Romel Joseph is already planning a return to Haiti to rebuild the school and continue teaching there.
“We can save two children, 20, 200, 300, 500 through education and music, and these children will make a difference,” Romel Joseph said.
Romel began to like music ________.

A.because he was blind since birth
B.after he had listened to a famous piece of music

f cars had wings,they could fly and that just might happen, beginning in 2011.The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its car-plane, the Transition, to customers by the end of 2011.
“It’s the next‘wow’vehicle,”said Terrafugia vice president Richard Gersh.“Anybody can buy a Ferrari, but as we say, Ferraris don’t fly.”
The car plane has wings that unfold for flying—a process the company says takes one minute—and fold back up for driving.A runway is still required to take off and land.
The Transition is being marketed more as a plane that drives than a car that flies, although it is both.The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.
The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly.They say it saves you the trouble from trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you’re good to go.When you land, you fold up the wings and hit the road.There are no expensive parking fees because you don’t have to store it at an airport—you park it in the garage at home.
The car-plane is designed to fly primarily under 10,000 feet.It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers.Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal(临界)conditions.
The Transition’s price tag: $194,000, But there may be additional charges for options like a radio, transponder or GPS.Another option is a full-plane parachute.
“If you get into a very awful situation, it is the necessary safety option,”Gersh said.
So far,the company has more than 70 orders with deposits.“We’re working very closely with them, but there are still some remaining steps,”Brown said.
We can learn from the first paragraph that.

A.car-planes will be popular in 2011
B.people might drive a car-plane in 2011
C.both Transition and Ferrari can take off and land
D.Richard Gersh is the vice president of Massachusetts

A.fold and unfold its wings B.unfold wings for flying
C.land in the airport D.meet flying safety regulations

B.To mcet aircraft regulations, the company has been working with FAA.
C.The car-plane may fly as high as normal planes.
D.People can park the car-plane in the garage at their home.
.The underlined word“it”in the last but one paragraph refers to.

Officials in a remote Russian city have drawn up a list of practical tips for locals on how to survive encounters (相遇) with bears, after growing numbers have wandered into the streets in search of food.
Officials in the city of Syktyvkar drew up the guidelines to guide the local people, after several bears were caught sight of in the city, going hungry after a heat wave shriveled their usual diet of nuts and berries.
The guide warns that city people there should stay calm and stand still if they meet with a bear. “Speak to the bear in a firm voice” and “Don’t turn your back on it,” it adds. In the worst case, if the bear attacks, the person should also be ready to attack, the guide says. “Shout angrily at it and look it straight in the eye,” the guide advises. “Bears have started coming into the areas where people live more and more often,” the city officials said in a statement. “Any encounter with a bear is unsafe for humans, so our task is to do all we can to prevent such accidents.”
In September, a bear attacked a 25-year-old man in a central street of the city, wounding him in the neck before he managed to run away, police said. “Three or four people who met with brown bears have been recorded recently,” the head of the hunting department in the regional agriculture organization, Alexander said.
Officials have asked police to patrol (巡逻) streets close to wooded areas in the evenings.
