The first bicycles were made of wood. After that, manufacturers used steel tubes. But the steel ones cost too much. The people in poorer countries want to have cheaper ones.
Izhar Gafni had an idea to make a cardboard bicycle able to support the weight of a human being. After three years hard work, he succeeded in creating this special bike. It is made of cardboard and 100% recycled materials. It costs less than $12.
The cardboard bike can hold a rider weighing up to 485 pounds. And if you don’t want to have it any more, you could just throw it into dustbin. And this will do no damage to the environment because it is easy to recycle.
When talking about his design, Izhar says, “It’s strong. It’s durable. It is cheap. What I like about it the most is: it’s made out of recycled cardboard.

Most musicians agree that the best violins were first made in Italy. They were made in Cremona, Italy, about 200 years ago. These violins sound better than any others. They even sound better than violins made today. Violin makers and scientists try to make instruments like the old Italian violins. But they aren't the same Musicians still prefer the old ones. No one really knows why these old Italian violins are so special, but many people think they have an answer.
Some people think it is the age of the violins. They say that today's violins will also sound wonderful someday. But there is a problem here. Not all old violins sound wonderful. Only those from Cremona are special. So age cannot be the answer. There must be something different about Cremona or those Italian violin makers.
Other people think the secret to those violins in the wood. The wood of the violin is very important. It must be from certain kinds of trees. It must not be too young or too old. Perhaps the violin makers of Cremona knew something special shout wood for violins.
But the kind of wood may not be so important. It may he more important to cut the wood in a special way. Wood for a violin must be cut very carefully. It has to be the right size and shape. The smallest difference will change the sound of the violin. Musicians sometimes think that this was the secret of the Italians. Maybe they understood more than we do about how to cut the wood.
Size and shape may not be the answer either. Scientists measured these old violins very carefully. They can make new ones that are exactly the same size and shape. But the new violins still do not sound as good as the old one. Some scientists think the secret may be the varnish, which covers the wood of the violin and makes it look shiny. It also helps the sound of the instrument. No one knows what the Italian violin makers used in their varnish. So no one can make the same varnish today.
There may never be other violins like the violins of Cremona. Their secret may be lost forever. Young musicians today hope: this is not true. They need fine violins. But there aren't very many of the old violins left. Also, the old violins are very expensive. Recently, a famous old Italian violin was sold for about US $300, 000!

Building blocks (积木) are still one of the most popular traditional toys today. They were first made of wood. Today, wooden building blocks are still used, but now there are more different types of building blocks for children to choose from, like plastic building blocks. The easy use and interesting design attract (吸引) children of all ages. Maybe that is why they are still welcomed today. Children build all kinds of things that they see in everyday life with building blocks. Building blocks are helpful for children to learn new things and many skills.
Building blocks can help children practice their languages. Most children talk to each other as they build things with these traditional toys. When some kids don’t know how to build things, they will also ask others for help.
In addition, this type of toy also helps develop the skills that children need in life. As they begin to join groups playing with building blocks, they learn to take turns, share, and solve problems with others.
However, these are not the only advantages of playing building blocks. Building blocks help develop children’s skills in math and science as well. They allow children to work according to the steps of scientific discovery. They are first to watch and to think, and then to test. Both traditional and modern toy building blocks come in different shapes, colors and sizes. These types of building blocks encourage children to develop skills in dividing things.

On the first evening, the three of us were tired after walking for about eight hours. We soon fell asleep. In the morning, I was surprised to find the bag of food had been open.
“Bears,” said Joe, “we should hang the food in a tree tonight.”
Later that day we stopped in a beautiful field by a river. We put up the tent and fell asleep. During the night the bears came again. This time they took the food from the tree.
“Bears can climb trees. They can smell food from a long way away,” said Ben.
“We must keep the camp clean. Bears must think our rubbish is food,” I said. “And we should make lots of noise, too. If they know where we are, they may not come any closer,” said Joe.
“But if you see a bear,” said Ben, “you mustn't make any sudden moves or make a sound, and you mustn’t run either. No one can run faster in the forest than a bear. And remember we don’t have a gun to keep us safe.” That night, we went to sleep ... or we tried to.
The next day, while the others were resting, I went for a walk in the forest. Suddenly, I saw a baby bear playing with some sticks and stones. He looked so soft and friendly, and I thought, “If I reach out, I can just touch him.”
There was a loud noise behind me.
I didn’t dare to move, not even turn my head. There was another loud noise. The baby bear looked up, and ran towards me. I turned pale and he ran past me into the woods.
I couldn’t turn round until a few minutes later. Then I saw the baby bear and his huge mother walking away.
I ran back to my friends. I have never run so fast.
For the next 10 days, every time there was sudden noise, my blood went cold.
1.Who moved the food bag on the first night?

3.What was the loud noise behind the writer?
A. It was the wind. The weather changed in the forest.
B. It was another baby bear. He wanted to play with stones, too.
C. It was the baby bear’s mother. She was coming to find her baby.
D. It was the writer’s friends. They were ready to fight with the bear.
4.Why did the writer run back fast to his friends?
