Do you often like to use disposable（一次性的） chopsticks when eating out? It’s time to drop this habit.
China products（生产） 80 billion pairs of disposable chopsticks every year. “This is enough to cover Tian’anmen Sqaure 363 times,” said Bai Guangxin, chairman of Jilin Forest Industry Group, at the National People’s Congress on March 8.
The government has made some rules to limit（限制）the use of disposable chopsticks. However, there are still many being produced.
“The production of such chopsticks is a heavy burden on national forests,” Bai added. A total of 20 million 20-year-old trees would have to be cut down to make way for this annual production.
Bai called on people to bring their own chopsticks whenever they are eating out. “We first need to bring a change to people’s eating habits and encourage everyone to carry their own chopsticks around.” He also said that there may be technology that can turn wild grass into disposable chopsticks in the future. Are there still many disposable chopsticks being produced ?

Put an ice cube from your fridge into a glass of water. You have a piece of string(线) 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers.
You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.
First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt(融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze(结冰) again.
After a minute or two you may raise the piece of string and with it you will raise your piece of ice!
This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don’t put enough salt, the water will freeze again.We must use when we carry out this experiment.
| A．a fridge | B．some food | C．a table | D．some salt |
How long will it take to carry out this experiment?
| A．More than three minutes. | B．Five minutes or two. |
| C．Only one minute or two. | D．About ten minutes. |
We can learn something about from the passage.
| A．physics | B．biology | C．chemistry | D．maths |
Old Cremona Violins
Most musicians(音乐家) agree that the best violins(小提琴) were first 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(乐器) like the Italian violins. But they aren’t the same. Musicians still prefer the old ones.
Some people think it is the age of the violins. But not all old violins sound wonderful. Only the old violins from Cremona are special(特殊的). So age cannot be the answer.
Other people think the secret to those violins is the wood. The wood must be from certain kinds of trees.
But the kind of wood may not be so important. It may be 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(形状). 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 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 ones. Some scientists think the secret may be the varnish. Varnish is what covers the wood of the violin. It makes the wood look shiny. It also helps the sound of the instrument. But no one knows what the Italian violin makers used in their varnish.The passage is about .

A lady has a problem with her daughter:
My nine-year-old daughter, Maria, is in Year Four. Every evening we get into homework battles(争执). Three afternoons a week, she has activities(netball, singing) after school and by the time we get home early, we argue(争论) about whether she should do her homework right after school, or if she should have some time to rest and play first. When Maria at last sits down to do her homework, she seems to want me there helping all the time, I do want to help her, but I’m sure that she is going to need to be able to do it on her own.
