Have you heard the expression “You are what you eat”? Well, do you like who you are? If not, break some bad eating habits and feel better about yourself.

Bad habit 1:

Many people often eat packaged ( = in small bags) foods at their work places, such as frozen dumplings, rice rolls and instant noodles (方便面), which have lots of fat and calories (热量).

The solution (解答): Read the instructions to find the healthiest foods that are low in salt and high in fiber (纤维). Also check to make sure they have ingredients (混合物) such as vegetables and grains (粮食). When possible, use packaged foods as part of a “home-cooked” meal. For example, frozen dumplings with fresh vegetables are better than dumplings alone.

Bad habit 2:

People without breakfast don’t have enough energy they need to get through the morning. Eating breakfast improves your attention, memory and feelings.

The solution: Always keep a kind of quick foods like yogurt (酸奶). Or have a standing order at a breakfast place.

Bad habit 3:

It takes your body at least 20 minutes to “tell” your brain that you are full, so fast eaters usually eat more than people who eat slowly.

The solution: Try to slow down. Try eating at least some of your meals without TV, hand phones or computers. Use a plate or bowl when you eat.

Bad habit 4:

Healthy snacks (小吃) between meals are fine. But when you snack instead of having real meals, you will not eat your meals regularly. And snack foods such as chips and sweets aren’t very healthy. That makes it easy to overeat.

The solution: To get more energy, allow yourself two healthy snacks a day. Choose snacks that will make you feel full. Try fruit, yogurt or nuts.

As we all know, bad habits can be broken. Take the first step toward a healthier eating habit — start following these tips today!

Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into an object. This is now possible with the help of 3D printers. Such machines were once used just by universities and big companies, but now, stores with 3D printing services are appearing around the United States.

Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The Jaycoxs offer 3D printing classes and services for anyone who is interested.

“I think 3D printing is going to be huge. It’s going to have a huge influence on society as a whole.” says KiChong Tran, one of the students in a recent class. He plans to open a 3D printing business in Cambodia (柬埔寨).

3D printing services are coming into American people’s life. The UPS Store is a nationwide retailer (零售商) that provides copying and other services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke Jones owns one of the stores in San Diego.

“The demand has been amazing. There has been a lot of interest from people. It’s been much more than I would have imagined.”

The UPS Store plans to add 3D printers in three more stores.

For $11, someone used a 3D printer to produce two small plastic parts as part of a knuckle (指节) for a hand. He works for the company which is testing finger prosthetics (假肢). He says the same–day or next-day printing services will speed up testing of parts and get them to patients faster.

Staples, an American store, is selling 3D printers on its website for as low as about $1,300. As with any technology - experts expect the printing speed to increase and the price to go down.

Bryan Jaycox requires $15 an hour to print an object. He also sets the price depending on the size of the object and up to $50 an hour for design and labor services.

Mr Jaycox thinks that within five years, 3D printing technology could become more user friendly. But KiChong Tran says even today’s technology can make a difference in a developing country like Cambodia.

“With 3D printing you can give them tools, so they are responsible more for their own development and they learn skills beyond just like learning English and becoming a tour guide or something like that. You can actually create things that give value to the world.”

He says it’s not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality.

2.What does the underlined part mean in this passage?

A. 3D printing is becoming popular in the world.

B. There is no 3D printing business in Cambodia.

C. The UPS Store is the biggest 3D printing company.

D. 3D printing plays the most important role in daily life.
