A recent research shows that physical activity(體育活動) may help students do better in their classes. The research comes because educators in some countries are reducing time for activities like P.E. class.
Researchers go over the results of fourteen studies. Twelve were from the United States, one from Canada and one from South Africa. The studies appeared between 2009 and 2013. They included more than 55,000 children, aged six to eighteen.
Thomas Singh, one of the researchers, says the studies showed a relationship between physical activity and scores on subjects such as math, English and reading. Ms. Singh offers some possible explanations (解釋):
“ There are, first, physiological (生理的) explanations, like more blood flow, and so more oxygen (氧氣) to the brain. Being physically active means there are more hormones（ 荷爾蒙） produced like endorphins ( 腦內(nèi)啡). And endorphins make your stress level lower and your mood improved, which means you will perform better in class. Also, students who take part in organized sports learn rules and how to follow them. This could improve their classroom behavior and help them know what they should do.
All in all, the finding tells us that physically active kids are more likely to do better in school. Ms. Singh says schools should consider the finding before they cut physical education programs. 
小題1:What led the researchers to do the studies?
A．Schools’cutting physical activity.
B．Their interest in physical activity.
C．The tests including about 55,000 children.
D．Kids’unsatisfying schooling performance.

What’s the most important thing in your life? Do you think about this question?
I began to think about it when I was just a little girl. I had a lot of friends and I loved playing with them. So I thought friendship(友誼) was the most important thing in life. If I had no friends, I would be very sad.
When I got older, I thought the most important thing was music. I was crazy about music at that time. To me, if I couldn’t sing or listen to music, my life would be boring.
When I was 12, I read a book that tells a beautiful story about the love between a mother and her child. I was happy to find that love was the most important thing. I thought love made my life beautiful.
Not long ago, I got a new answer to the question from another book. “Happiness is the destination(目標(biāo)) for everyone.” the writer said.
Soon I began to understand friendship, music, love and happiness are all very important to us. These important things make our lives colourful and beautiful.
What’s the most important thing in life now? I still don’t have the answer. However, I don’t want to know. I just want to care about everything important in my life.

Do you think that living a hungry life is last century’s story? Well, it may be this century’s headline.
The world has growing worries about a global food shortage. Right now, there are still 870 million hungry people in the world, according to a survey of the UN’s Food and Agriculture Organization. Children can’t escape this, either. Around fifteen million children die of hungry each year.
What’s causing food shortages? There are several reasons.
There are now more droughts and floods. This is very harmful to farmers and their ability to grow food.
Besides, with the growing population, feeding everyone becomes more difficult. There are a little more than seven billion people in the world. By 2050, the world population will be more than nine billion.
Another reason is food waste. The average person throws away 50kg of food every year.
How can we help with food shortages? The easiest way is to cut down on food waste.
Next time before throwing away the food on your plate, just think how much work has been done to make it. By buying less, we waste less. This takes the pressure off producing so much food. And it helps to solve the problem of food shortage.
You can also ask your schoolmates to join you.
In 2013, researchers at Kansas State University in the US put up short anti-waste slogans(標(biāo)語) in dining rooms “Think Before You Waste”. Guess what happened? Students wasted fifteen percent less food after that!
The author of the study said, “You don’t need a huge activity to make a difference.”
Reasons of food shortage
小題1:_________________________________
The growing population.
小題2:___________________________________
Ways of 小題3:___________
小題4:___________________________________
Ask the other students to join in your anti-waste work.

A girl went to her father to ask for his suggestion. She was having a        time in life, and it seemed that as soon as one problem disappeared another one         in its place.
Her father, a chef, took her into the kichen. He poured water into three pans and put them on to boil. After the water boiled, he put some carrots into the first pan, some         into the second pan and coffee into the last one. He waited without saying a word.
After 20 minutes, her father turned         the stove(爐子), took out the carrots and the eggs and put them in a bowl. He poured the coffee into a cup.
He asked his daughter, “Dear,         do you see?”
“Carrots, eggs, and coffee”, she replied.
“Touch the carrots,” he told her. She did and felt that the carrots were       . After that he asked her to take an egg and break it. She found that the egg was hard.       , her father asked her to taste the coffee.
She asked, “What’s the          , Father?”
Her father said, “As you see, each thing reacted(起反應(yīng)) differently to the boiling water. The strong and hard carrots became soft and weak after boiling. The fragile(脆弱的) eggs became hard after being cooked. The coffee beans were very special, but they changed in the water, too.”
