When we think about vitamin C, all guess that we're talking about oranges, right? Well, that's not (complete) the full story about this awesome vitamin. Cancer prevention, heart health and immune (免疫) function boosting are a few roles vitamin C (play) in keeping us healthy. Apart vitamin pills and powders, fruits and vegetables are our best sources (need) for this super vitamin. Cabbage, as an example, is great source of vitamin C. But do you know that red bell peppers have almost 50% (many) vitamin C than oranges?

Many kinds of fruits like strawberries also carry rich vitamin C and are quite not difficult  (eat) when we know they can help us fight off that common cold everyone will catch around seasonal changes. Just a few (fact) bounce around our head about some of the foods high in vitamin C that can boost our immune system, help our heart  fight off those terrible cancer cells. 

However we phrase it, it is hard to find a reason not to boost our vitamin C intake after seeing all the  (amaze) benefits it can give to us.

Bus driver Sondra Artis had just picked up the last student on her route. As she headed towards Surry County Schools, the driver 1  a burning smell in the air. When a student asked her what was wrong, she did her best to 2  her growing worry. 

"I wiped the window and I said, ‘Is that steam or smoke?' I said calmly," Sondra recalled. "As I pressed on the gas, more came out. I just had to get them off that 3 . " Sondra pulled into a church parking lot and turned to 4 the 20 students on board. She reminded them of the evacuation drills (疏散演习) they 5 at the beginning of the year and directed older 6 to leave by the backdoor and younger students through the 7 .

"I told the kids that," You know, we 8 in the beginning of the year, but this is going to be 9 , so I need you to be calm," said Sondra.

The students hurried to the 10  as smoke began to fill the bus. They were 11  , but Sondra remained calm throughout the evacuation. When they were out, she went back onto the bus to make sure everyone escaped 12  . 

Seconds after they all disembarked (下车) , the bus 13  fire. Another bus came to the 14  to take the children to school, and Sondra was happy that everything 15  okay.

How to prepare for an exam is a big question that you always ask yourself. Here are some tips that may help you.

Never fear or hate exam and be confident.

Some students study well but still may be much afraid of exams and due to this reason they get upset and won't be able to get marks.You have to be confident and it is of great help for you to gain success.

Prepare a good timetable.

Prepare a timetable before starting the study.Difficult subjects can be given more time and easier ones less, but most importantly you should spare some time for rest.

Select a proper atmosphere for studying.

Studying atmosphere plays a very important role.So pick a place where you feel comfortable. That is where you feel relaxed and can pay attention to what you are doing. Make sure that while you are studying a subject you are focusing on it only. So keep the books of other subjects away from your eyesight so that you won't be upset about all the things you have to learn.

Make notes while studying.

This is a very important point. While studying, make small notes. The note should be short and clear to make the review easier.Yet don't try to cover everything in it.

On the night before exam you have to sleep well, at least 6 hours and not more than 8 hours. Remember this will have a great effect on your exam. And have your food as in your daily diet.

A. Sleep well and eat well.

B. So try to present answers in points.

C. This should include all the subjects.

D. Can anyone study well while others around are watching TV?

E. A good note shall include the most important points.

F. This will be of great use to your coming exams.

G. So leave all your fears and free your mind before starting the study.

Many scientists believe our love of sugar may actually be an addiction. When we eat or drink sugary foods, the sugar enters our blood and affects parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has a particularly strong effect. In this way, it is in fact an addictive drug, which doctors suggest we all should cut down on. 

"It seems like every time I study an illness and search for the first cause, I find my way back to sugar," says scientist Richard Johnson. One-third of adults worldwide have high blood pressure, and up to 347 million adults have diabetes (糖尿病) . Why? "Sugar, we believe is one of the culprits, if not the major reason," says Johnson.

Our bodies are designed to survive on very little sugar. Early humans often had very little food so our bodies learned to be very efficient in storing sugar as fat. In this way, we had energy stored when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us. 

So what is the solution? It's: obvious that we need to eat less sugar. The trouble is, in today's world, it's extremely difficult to avoid. From breakfast cereals (谷物) to after-dinner desserts, our foods are increasingly filled with it.

But there are those who are fighting back against sugar. Many schools are replacing sugary desserts with healthier food like fruit. Other schools are growing their own food in gardens, or building facilities like walking tracks so students and others in the community can exercise.

Unless you are fortunate enough to know an NBA player, Ryan Martin is probably. the best basketball player you'll ever meet. Unlike those who fly up and down the court (球场) , however, Martin is forced to take a different approach; he doesn't have legs.

Martin, a 33-year old man, is a professional wheelchair basketball player. His achievements have taken him halfway around the world to play in Spain for the last seven years. There he made a comfortable living playing basketball and working with some of the greatest athletes in the world. 

"A good wheelchair player can make $50, 000 a year, while a star can make six figures," said Martin. What's more, he couldn't see his family for months and European cities were unfriendly to the disabled. He also had to learn Spanish. Martin, however, overcame those drawbacks (困难) .

He started by playing basketball when he was 12. It didn't take long for him to fall in love with the sport and, after graduating from Somers High, he attended Southwest Minnesota State University on a basketball scholarship. In college, he scored over 1, 000 points in his career and set several school records.

And he works as hard— if not harder— than any other professional athlete. "He destroys me," said Gina Navarra, who works out with Martin on occasion. "What he does amazes me."

Martin also recognizes that, at age 33, he's in the back end of his career. With that in mind, he has been focusing more and more on his foundation.

"I have 12 brothers and sisters. College gave me a true sense of achievement. The foundation is designed to give those with disabilities the opportunity to realize the dreams that I once had," Martin said.

"I'm not saying that out of a sense of pity," he said. "I realize how fortunate I am to have achieved what I have. But I want to open doors for people."
