Can plant 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(捕蝇草).
The Venus flytrap is a very strange plant. It grows in dry parts of the United States. Its leaves are like the pages of the book.. They can open and close very quickly. Inside the leaves, there are three small hairs. If a fly(苍蝇) touches one of the hairs, the leaf closes very quickly. Then the fly can’t go out. In about half an hour, the leaf presses the fly until it is dead. Then, the plant covers the fly. Slowly, the plant eats the fly. Why do plants do it? Most plants get what they need from the sun, the air, and the ground. In some places, the ground is very poor. It doesn’t have all the important things, 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.

About ten minutes later, the door opened and Miss Liu 6 came in, smiling. She didn't say sorry to the class. We felt 7 angry. The teacher often told us never to be late for class and said it was 8 manners to be late. She also said that if we were late, we should make an apology (道歉) 9 at once or after class. But now she was late and had kept the whole class waiting for such a long time and didn't even tell us the reason. It was unfair. At this moment, Miss Liu picked up a piece of chalk(粉笔) and 10 "Teacher IsLate" on the blackboard and said that was the topic of our composition today.

Several Asian hospitals are doing experiments with tele-medicine. Tele-medicine is a technology that allows doctors to "see" patients without them being in the same place. This is made possible through high-speed communication networks （网络）.At both ends of the line, the
way of video-meeting lets them see and talk to each other. Blood pressure (血压) and body temperature are directly shown on computers.
Tele-medicine is already in wide use in some places such as the United States and Germany. Among other uses, village doctors hold "consultations (会诊)" with far-away experts（专家）. The experts can also help them during operations.
Tele-medicine has been slow to reach Asia because of high costs, besides other reasons. When things improve, this technology will develop very fast. Chinese University of Hong Kong's medical school has joined a big hospital in Beijing, and Thailand is building a tele-medicine station connecting 20 areas.
Tele-medicine will do good to patients because doctors from different places can see them and give their medical advice. The help is quite important if the disease is an unusual one. It also helps spread medical knowledge among experts.
As tele-medicine develops well, its costs will be lower and it will become very popular in the medical field.
