“Early to bed and early to rise, makes a person healthy, wealthy and wise.” These words of Benjamin Franklin have been backed by science. It has been proved that morning people are persistent and active. It leads to better performance, greater success, and higher standards of living. Rising up early also reduces stress because it gives you the time to squeeze in a workout before you get distracted(心烦意乱的).     1    

Recent research has found that late sleepers generally need about 248 more calories than those who rise early. They prefer to only eat half as much fruit and vegetables and twice as much fast food as those early risers.

    2    You should limit the usage of smartphones at once before going to bed, which will help you become an early riser. Researchers have also said that early morning is the best time to study and gain knowledge. It will help you in staying ahead in the class and keep your grades up.

If you get into the habit of rising early and going to bed early you are more likely to have a better sleeping pattern.     3    You will feel more energetic throughout the day, and complete your goals in a faster and more productive manner. Most businessmen are early risers as they believe it is the key to successful, happy and satisfied.

Getting up early has many benefits(益处)for both your body and your mind.     4     If you don’t get into the habit of waking up before the rest of the world, you won’t be able to change the world.

【推荐3】A kind of new houses in California is selling quite fast. In a short time, people buy 82 ones and they need 1000 more. And the factories will build them soon—for they are able to build one in less than 24 hours.

Why can they do it so fast? Because 3D printing (打印) helps to make it. 3D printing not only builds a house with less time, but also costs less and is more environmentally (环境上) friendly. And there are different styles of 3D printed houses for people to choose.

3D printing is developing (发展) very fast. But there are some problems with 3D printed houses. First, the house “printed” out may not be strong enough. Second, while building houses layer by layer (逐层地), there may be some differences between layers. Some layers may be a little thinner or thicker than others. Finally, there are now fewer types of 3D printing materials (材料) for us to use.

However, the future of 3D printed houses is promising. In India, there are not enough houses. The country wants to use 3D printing to solve the problem. If successful, buildings by 3D printing may go popular. We can also use it to build offices and other buildings. NASA wants to use 3D printing to build something on Mars and the Moon.
