    Having good communication skills is important. They can help you with performances in class, during the job hunting, having arguments and in a variety of other situations. 1.

1. Understanding the basics of communication skills.

Communication is the process (过程) of delivering signals or messages between a sender and a receiver through various methods. 2.

2. Trying to attract the attention of your audience.

Whether you are speaking or listening, looking into the eyes of the person with whom you are having a conversation with can make the communication more successful. Eye-contact expresses interest and encourages your partner to be interested in you in return.

You can use gestures to help. 3. Make your whole body talk. Use smaller gestures for individuals and small groups. The gestures should get larger as the group that one is talking to increases in size.

3. 4.

People will think of you as nervous and unsure of yourself if you talk fast. However, be careful not to slow down to the point where people begin to finish the sentence just to help you finish.

People will judge your ability through your vocabulary. 5. Improve your vocabulary by reading new words regularly. Look in the dictionary to help you learn how to pronounce a new word.

Communication increases happiness and love and makes you more popular. When you improve how you talk and present yourself, you will build your confidence, self-esteem (自尊) and social life.

G.Here are some tricks you can use to improve your communication skills.

    Anything made of plastic or metal can be 3D printed nowadays — bicycles, toys, tools... even replacement body parts! But the latest trend in 3D printing may be food. Scientists and chefs are putting their heads together to create printed food.

Several 3D printers designed for food are now on the market. Anything that can be made into a soft wet mixture can be squeezed (挤压) from a tube in a 3D printer. Instead of ink, these printers can use fruits, vegetables, proteins, sweets, and more. This makes for lots of combinations that can be healthy, yummy, and even artistic.

Most 3D printers don’t actually cook the food, at least not yet. Engineers at Columbia University’s Creative Machines Lab invented an oven (烤箱) that cooks 3D-printed pizza with laser beams (激光束). A special computer program controls the lasers, heating each part of the pizza to perfection. Unlike regular ovens, lasers can carefully cook each thin piece of 3D-printed food.

In the future, food can be made with a 3D printer to meet our needs. For example, a hospital could design meals to meet patients’ dietary needs. Vitamins, minerals, and even medicines can be mixed right in. A 3D printer can make food appealing. Foods that someone may not like might be more attractive after 3D printing. Maybe that food you dislike wouldn’t seem so bad if it looked like a castle!

The idea of 3D printed food may seem very modern. In fact, NASA (美国国家航空航天局) has been researching the topic for more than ten years. On a long travel, it’s important to have food that is easy to make, tastes good, and has the nutrients astronauts need to stay healthy. Printing food on demand may soon be into the space!
