Snack time is a part of the day for children of all ages. But new research suggests that kids snacking in big groups could be at risk for obesity.
Scientists from American University looked at the eating behavior of 54 kids between the ages of 2 and 6. At snack time, the scientist watched the amount of food each child ate while they were in groups of either three or nine. According to the study, the more children there are in a group, the more likely they are to eat more. Those in the larger group ate nearly 30 percent more than those in the smaller group, and they actually ate faster.
Since this is the first such study in children, scientists are quick to point out the importance of encouraging healthy habits in kids as early as possible.
“If you know kids eat more in large groups, it seems perfect to use this information to keep snack groups small or use small tables,” says Dr. Jana Klauer, an expert in New York.
Smaller groups would allow for a quiet and more relaxing environment-a perfect chance to teach children about food, manners and how to know when they feel full. “This would have an effect on kids' eating,” adds Klauer. “They would slow down and eat less.”
小題1:How many times have the scientists done such study according to the passage?
A．Once B．Twice C．Three times D．Many times
小題2:The underlined word means”      ”in Chinese.
A．健康B．肥胖C．瘦弱D．服從
小題3:Why do children in smaller groups lose weight?
A．Because children in smaller groups eat faster.
B．Because children in smaller groups don't like eating.
C．Because children in smaller groups don't know about food.
D．Because children in smaller groups eat slowly and eat less.
小題4:The best title of the passage is “         ”
A．Snack Time B．Different Groups
C．Eating More D．Food for Kids

Did you see snow in your hometown last winter? Did you feel it was warmer than before?
"There have been 21 warm winters in China since 1986," said scientists. They also said that in the past 100 years, as the global (全球的) temperatures went up by 0.74 °C , the temperature in North China has climbed 1.4 °C in only 50 years.
China needs to take quick action to cut carbon dioxide emission (排放)
because it's the main reason for global warming. The good news is that China has seen the importance of going green. China set the goal of cutting energy use by 20% and pollution emission by 10% in the 11th Five-Year Plan.
Can you slow down global warming? Sure! You and your family can take steps to cut the amount of carbon dioxide that is sent out into the air.

It is well known that everyone has his own dream as well as his own future. But do you know what future really is? I have to say that future is now. That is to say, we must treasure every minute now. If we want to have a bright future, we should know how important time is and use it well.
There is an old English saying, “Gain (得到) time, gain life.” Then what’s time? Time is something that we can’t see or touch, but we feel it passing by. Time is always with us. When we are at table, time passes; when we play, time goes by unnoticeable. We always say “Time is money”, but time is even more precious (珍貴的) than money, because when money is spent, we can make it back. But if time is gone away, it will never return. So, some of us even say time is priceless (無(wú)價(jià)的).
We should always remember: future is now. For us students, we should try our best to work hard in order to create a great future of our own. We should make the best use of every hour and be the master of today. We should do everything before us as well as possible. And never put off (推遲) what can be done today till tomorrow.
As we all know, “Time and tide wait for no man.” If you waste today, you will regret tomorrow. So from now on, work hard. Tomorrow will be better, and your future will be brighter. Remember: “No pains, no gains.” Today’s hard work is the cause of tomorrow’s harvest.

When do you think of a forest, what do you see? Just trees? Or do you see many other things, such as singing birds, colorful plants and wild flowers?
The forest is a whole world of its own. It is full of many different living things(生物). But even though they are all different, they have one thing in common: they all need each other in order to live on.
The trees feed the forest “people” by making food in their leaves; by using sunlight to join water and minerals(礦物) from the soil and air. Their deep network of roots joins the soil together and stops it from dying out, making it possible for living things to live in it.
Human beings(人類) are like the living things in the forest. We need one another in order to live. We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and clerks(售貨員) to sell it to us. We need people to prepare our food and cook it and others to take our waste things away. Then, of course, we need doctors, nurses, government leaders, mailmen, telephone operators, and many others.
We also need other human beings in another way. We need people for friendship, to talk over our problems, exchange ideas. Think how lonely and unhappy you would be if you lived all alone.
Life is a matter of giving and taking. We need to help other people as much as we need other people to help us. Think what a good feeling you have when you have done something for someone else!
小題1:According to the text, colorful plants and flowers live on _____.
A．the leaves of the treesB．water and minerals
