It is usually seen as old people’s problem, but more and more young people have the problem of high blood pressure(高血压).

As many as 3.8% of teenagers aged from 15 to 20 are threatened by high blood pressure, according to a survey of 10,000 young people of the age group in Harbin, Heilongjiang Province. The number is much larger than in the past years and doctors are worried that it could cause more health problems.

Research shows that teenagers with higher-than-normal blood pressure are easier to have heart trouble later in life.

The doctors say it is now known that high blood pressure has risen fast among young people, so teenagers are experiencing the most important time in their lives.

Unhealthy habits and pressure are the main causes of high blood pressure. Children should have more vegetables and fruit so that there are enough vitamins in the bodies. Besides, children should keep away from a lot of fat, salt and sweets.

Students must also learn to deal with study pressure if they want to stay healthy. Taking more exercise rather than watching TV or playing computer games can make the body strong and reduce the chances of getting high blood pressure.

3D printing is becoming more ancl more popular. We are now able to print things such as clothing, musical instruments and even cars. People and businesses are able to create the things they need very quickly and easily by using 3D printers.

But can you imagine printing food? Some scientists are trying to change the dining experience completely by doing this. They hope that having a 3D printer in the kitchen will become as common as the blender or microwave. Scientists say that they are easy to use: you simply have to choose a recipe(食谱) and put the uncooked food“inks” into the printer to make the food you want. This means that it would be very quick and easy to create tasty and healthy meals.

Using 3D printers to create your meals would also be saving the environment, There would be less need for traditional growing, shipping and packaging steps as food production would be a lot quicker and better. For example, tree leaves and insects could be turned into tasty products!

Printing food could also help people who have a swallowing(香咽) trouble. They could program the printer to print softer kinds of their favorite foods so that they would not have difficulty swallowing them.

However, some people think that a future of 3D-printed food would be a disaster. It could take away many jobs, including those for growing, shipping and packaging food. Imagine a world where there was no need for farming or growing crops and the same tastes and structures could be printed from an uncooked “food ink”. Traditional cafes and restaurants might lose business, too.

Also, there are worries about the healthy value of printed food: is it really possible to get what we need from food-based “inks” or something like that?

As we know, cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button.
