Good health is very important. Everyone should do all he can to stay healthy. Being in good health means having both body and mind in good order, free from illness and pain.
Good food, plenty of water, cleanness and plenty of rest all help in keeping our machines running as they should. Food does many things for our bodies. It gives what we need for keeping good health. It gives us energy for work and play. No food gives everything we need. We should eat foods of different kinds. Having enough to eat is not the same as having the right food.
The water we drink helps wash away wastes formed inside our bodies. It also puts back the water we lose when we perspire(流汗). Our bodies are actually more than half water. We must drink enough to replace what we lose.
We feel better and look better when we are clean. A bath every one or two days is a good rule for most of us. Brushing our teeth is important part of keeping clean.
Sleep is the best kind of rest. Growing children need more sleep than grown-ups. Children's bodies not only have to be repaired; they also have to grow, No one's body can grow bigger properly while he is working and playing and wearing it out (疲勞).
It has been useful to work for good health. Millions of years ago, people live only 20 years. Now people can live about 70 years. It has gone up 20 years just since the beginning of the present century.
小題1:You should have foods of different kinds because _________.
A．some foods are not good
B．no food can give everything you need
C．different foods taste different
D．different people like different foods
小題2:We must drink enough water to replace what we lose. Here replace means   .

7 January, 2014
A new report says more and more international students are attending colleges and universities in the United States. It also notes a large increase in the number of international students from China.
These findings are from the latest Open Doors Report. The report documents the record number of international students in the United States during 2012, 2013 school year. It says more than seven hundred sixty-four thousand four-hundred such students were attending American colleges and universities during the last two years. That represents an increase of almost six percent than one year earlier.
On the other hand, the number of Americans studying overseas (海外) increased by one percent, which reached nineteen thousand this year.
The report says one hundred ninety-four thousand students at American colleges and universities were from
China. That is an increase of more than twenty-three percent over the year before. Peggy Blumenthal, an expert(專(zhuān)家) of international education, described the effect of the increase in Chinese students.
"Now they have been coming for some time. But this year was the highest level ever." She says many Chinese families are able to pay for the highest-quality education for their children. The children mainly choose to study in America.
"We know many of them have enough income to be able to afford to send them anywhere in the world that they want to go. And for the most part, looking around the world, Chinese students still prefer to come to the United States as their choice."
Chinese students are not the only ones who want to attend American colleges and universities. After China, India sends the second largest number of students to the United States for higher education. India has about one hundred thousand students in American schools. South Korea is third with about seventy two thousand students.
Why do so many foreign students study in the United States? Peggy Blumenthal provides one reason.
"The advantage America has is that we have a huge system and a very perfect system. So there are over four thousand universities and colleges in the United States. Among them are some top ones in the world, and what that tells us is there is still a lot of room to host international students."
Foreign students represent less than four percent of the total student population in American higher education. And from Learning English, that's the VOA Special English Education Report. I'm Bob Doughty. Thanks for listening.
小題1:Bob Doughty seems to be ________.
A．a(chǎn)n exchange student from the USA

Can plants eat people? Probably not, but there are many plants that eat meat. Some of them are big, and they can eat small animals. One famous meat-eating plant is the Venus flytrap.
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of a book. (A) They can open and close very quickly. Inside the leaves, there are three small hairs. If an insect touches one of the hairs, the leaf closes quickly. The insect cannot get out. In about half an hour, the leaf presses the insect until it is dead. Then, the plant covers the insect with a special liquid （液體）. Slowly, the plant eats the insect.
(B) Plants are living things that have leaves and roots and grow in earth. Most of them get energy from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all the important things that plants need, especially nitrogen （氮）. Animal meat has a lot of nitrogen, so some plants eat meat to get what they need. Let’s hope that some of the bigger plants don’t get the same idea!
小題1:__ Can plants get energy from the air?
小題2:__Why is Venus flytrap a famous plant?
小題3:__In some places, why do some plants get energy from animal meat?
小題4:__寫(xiě)出（A）處劃線單詞they所指代的名詞。
