E-mail can be a powerful new tool in improving communication between patients and doctors, according to one expert.

“Using the Internet, doctors can answer more questions from more patients in a shorter time,” writes Dr. Dada Pal, a famous doctor in Manchester, UK.

　　According to Pal, nearly forty percent of American patients say they have used e-mail to communicate with a doctor.

　　He notes, however, that although patients have such interest, only up to two percent of doctors in the united States offer e-mail service.

　　Using e-mail, doctors can make sure of their advice and point, patient to patient information materials and other resources on the Internet. It's said that more than ten thousand healthoriented websites already exist now.

　　However, some people worry that widespread use of medical e-mail might set up two kinds of care—one for Internet“haves” and another for the “have-nots”

　　But Pal points out that“ by the year 2000 nearly every library will offer （Internet and e-mail） services in the United States, allowing even low-income patients to use such means.” Pal also talks about other possible barriers to the acceptance of medical e-mail.

　　“Doctors may be unwilling to offer e-mail services for fear of increasing workload and uncertainty about payment for the time they spent,” he explains, and patients may worry that their medical information might be read by others.“But these problems can all be solved,” he adds.

　　E-mail may well help us a lot in health care, Pal concludes. “Patients can get in normal clinics,” he points out, “and they might find communication on the information superhighway less fearful, than face-to-face dialogues with their doctors.”

What do you do if you're stranded（处于困境的）on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane.

　　Body signals（信号）

　　Pilots from different countries understand body signals if they have the correct training. When you wave your arms up and down in a straight line, it means "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend（弯曲）your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side.

　　Smoke signals

　　The smoke from a fire can be seen from far away, so it's a good way to draw attention. If the weather is dry, it isn't hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a fire unless you're sure that it can't spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.

　　Ground-to-air signals

　　It's a good idea to build some signals, too. Use large pieces of wood to make the symbols(标记). If you can't find any wood, use earth. Some useful symbols are:

　　F "I need food and water."

　　II "I need medicine."

　　I "I am badly hurt."

　　X" I am unable to move from here."

　　Pilots' replies

　　If the pilot lowers the plane's wings from side to side, this means "message received and understood". (At night, the pilot flashes the plane's green lights.) If the pilots flies the plane in a clockwise circle, this means "message received but not understood".(At night, the pilot flashes the plane's red lights.)

However, there is no signal which means "message not received". Why not?

We’ve talked about snails (蜗牛) and their slow move. But much of the time snails don’t move at all. They are in their shells (壳) —sleeping.

Hot sun will dry out a snail’s body. So at the least sign of hot sun, a snail draws its body into his shell. A snail will die in a heavy rain. So when it rains, a snail does the same thing, too. A snail can sleep for as long as it needs to. It spends all the winter months in its shell, asleep.

In the spring the snail wakes up. Its body, about three inches long, comes out from the shell. When hungry, the snail looks for food. Its eyes, at the end of the top feelers (触角), are very weak. But its sense (感觉) of smell is very strong. It helps the snail to find food and the new greens.

A snail’s mouth is no bigger than the point of a pin (大头针). Yet it has 256,000 teeth! The teeth are very small, and you can’t see them. If you put a snail in a hard paper box, it will eat its way out! And if a snail wears out its teeth, it will grow new ones.
