Besides providing a perfect environment for sea plants and animals to live in, seawater has other values, one of which is that it constantly moves, and its movements produce energy.
The most obvious movements are the waves and the tides. Winds cause the waves, and the gravitational pull of the moon and the sun causes the tides. In places like the Bay of Fundy in Canada, the difference between the high and low tide level can be as much as 40 feet.
France and Britain are now trying to use energy in the tides to produce electricity. Waves can produce electricity and some experiments are taking place to learn more about this. One of the most encouraging areas of research uses the difference between the temperature of seawater at the surface and deep down to produce electricity. Waves and tides are caused by ________ .
| A．the same forces | B．different forces | C．their own movements | D．plants and animals |
It can be inferred from the passage that __________ .
| A．waves as well as the energy in the tide can produce electricity |
| B．the highest tide is 40 feet higher than the lowest one at the sea |
| C．many countries in the world have made the most of energy produced by seawater |
| D．it is being tried in some developed countries to use energy in the tides to produce electricity |
The best title for the passage is ______.
| A．Tides and Waves | B．How to Produce Electricity | C．Seawater | D．Another Cheap Energy |
It was the summer of 1965. DeLuca, then 17, visited Peter Buck, a family friend. Buck asked DeLuca about his plans for the future. “I’m going to col
lege, but I need a way to pay for it,” DeLuca recalls saying. “Buck said, ‘You should open a sandwich shop.’”
That afternoon, they agreed to be partners. And they set a goal: to open 32 stores in ten years. After doing some research, Buck wrote a check for $1000. DeLuca rented a storefront (店面) in Connecticut, and when they couldn’t cover their start-up costs, Buck kicked in another $1000.
But business didn’t go smoothly as they expected. DeLuca says, “After six months, we were doing poorly, but we didn’t know how badly, because we didn’t have any financial controls.” All he and Buck knew was that their sales were lower than their costs.
DeLuca was managing the store and going to the University of Bridgeport at the same time. Buck was working at his day job as a nuclear physicist in New York. They’d meet Monday evenings and brainstorm ideas for keeping the business running. “We convinced ourselves to open a second store. We figured we could tell the public, ‘We are so successful, we are opening a second store.’” And they did—in the spring of 1966. Still, it was a lot of learning by trial and error.
But the partners’ learn-as-you-go approach turned out to be their greatest s
trength. Every Friday, DeLuca would drive a
round and hand-deliver the checks to pay their suppliers. “It probably took me two and a half hours and it wasn’
t necessary, but as a result, the suppliers got to know me very well, and the personal relationships established really helped out,” DeLuca says.
And having a goal was also important. “There are so many problems that can get you down. You just have to keep working toward your goal,” DeLuca adds.
DeLuca ended up founding Subway Sandwich, the multimillion-dollar restaurant chain.DeLuca opened the first sandwich shop in order to ____.

| A．It stood at an unfavorable place. |
| B．It lowered the prices to promote sales. |

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 unhealt
hy 49 years old and have come to the conclusion that it’s now or never, so I a
m 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 appr
oach to the living foods.
Last week I atte
mpted 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 t
hrew 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.The author must have ________ before she wrote this article.

Many children first learn the value of money by receiving an allowance. Parents often give th
eir 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 ea
ch 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 wan
t. 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 doo
r 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 |

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 do
esn’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 ________.

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 1,4
30 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 i
nto 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 fro
m 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 |
lt takes the car-plane one minute to .
| A．fold and unfold its wings | B．unfold wings for flying |
| C．land in the airport | D．meet flying safety regulations |

A.The car-plane needs a runway to take off and land.
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 .
| A．the radio | B．the transponder |
