The Great Pyramid(金字塔)was built nearly 5,000 years ago for a king called Khufu. It is on the west bank of the Nile River. In fact, all the pyramids along the Nile River are on its west bank. The ancient Egyptians thought of the rising of the sun as the beginning of life and the setting of the sun as the end of life. This is why their bodies were buried on the west of the Nile.

    It is very hard to realize just how big the Great pyramid is. It has over 2,000,000 pieces of stones. Most of these big stones weigh two and a half tons each. Some even weigh fifteen tons. Without machinery, the ancient Egyptians cut and moved and lifted each of these stones. Almost all the stones came from the east bank of the Nile, and they were taken across the river in boat. It took more than 100,000 people twenty years to build the Great Pyramid.

    The Great Pyramid is over 450 feet high today. Each of the sides of the Pyramid is 755 feet long. It takes about twenty minutes to walk all the way around it.

    Good health is the most valuable thing a person can have but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape, eat right food, get enough sleep, and exercise regularly.

    Proper nutrition is important for good health. Your body cannot work well unless it receives the proper kind "fuel". Don't eat too much food with lots of sugar and fat, eat plenty of foods high in protein, like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins and minerals. However, don't overeat It is not helpful to be overweight

    Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality(人的个性).Be sure to allow yourself from seven to nine hours of sleep each. If you do, your body will feel strong and refreshed, and your mind will be sharp.

    Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span(寿命). Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on. Sports are not only good for your body, but they are enjoyable and interesting, too.

    If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.

    Adults understand what it feels like to be flooded with objects. Why do we often assume that more is more when it comes to kids and their belongings? The good news is that I can help my own kids learn earlier than I did how to live more with less.

    I found the pre-holidays a good time to encourage young children to donate less-used things, and it worked. Because of our efforts, our daughter Georgia did decide to donate a large bag of toys to a little girl whose mother was unable to pay for her holiday due to illness. She chose to sell a few larger objects that were less often used when we promised to put the money into her school fund(基金)(our kindergarten daughter is serious about becoming a doctor)

    For weeks, I've been thinking of bigger, deeper questions: How do we make it a habit for them? And how do we train ourselves to help them live with, need, and use less? Yesterday, I sat with my son, Shepherd, determined to test my own theory on this. I decided to play with him with only one toy for as long as it would keep his interest. I expected that one toy would keep his attention for about five minutes, ten minutes, max. I chose a red rubber ball-simple, universally available. We passed it, he tried to put it in his mouth, he tried bouncing it, rolling it, sitting on it, throwing it. It was totally, completely enough for him. Before I knew it an hour had passed and it was time to move on to lunch.

    We both became absorbed in the simplicity of playing together. He had my full attention and I had his. My little experiment to find joy in a single object worked for both of us.

China is the home of tea. Since ancient times, tea {#blank#}1{#/blank#} (become) part of Chinese culture, leaving its smell in poems and customs. Many tea lovers enjoy tea not only for its taste, {#blank#}2{#/blank#} for the beauty of tea ceremonies.

 {#blank#}3{#/blank#} (traditional), picking tea leaves is an important activity in spring in South China. The earliest batch (批) of tea is often ready to be picked before Qingming, in early April {#blank#}4{#/blank#} the temperature begins to rise and rain increases. This kind of tea, called Mingqian tea, is {#blank#}5{#/blank#} (high) praised for its good quality.

East China's Zhejiang province is considered as {#blank#}6{#/blank#} major producer of tea. White Tea in Huzhou city's Anji county and West Lake Longjing Tea in Hangzhou are famous in both China and abroad. In spring, local hills of those places are filled with tea workers {#blank#}7{#/blank#}(work) on their land. In the busy seasons, {#blank#}8{#/blank#} (tourist) from different areas of the country travel there {#blank#}9{#/blank#} (see) the sights of tea farms and enjoy a freshly prepared cup of tea.

Thousands of years ago, by the hands of the Chinese people, a leaf {#blank#}10{#/blank#} (make) into a delicious drink. It has traveled a long way and continues to play a role in Chinese culture.

There's a useful concept from psychology that helps explain why good people do things that harm the environment: the false consensus effect. That's where we overvalue how acceptable and prevalent（普遍的） our own behavior is in society. Put simply, if you're doing something （even if you secretly know you probably shouldn't）, you're more likely to think plenty of other people do it too. What's more, you likely overestimate how much other people think that behavior is broadly OK.

This bias（偏见） allows people to justify socially unacceptable or illegal behaviors. Researchers have observed the false consensus effect in drug use and illegal hunting. More recently, conservationists are beginning to reveal how this effect contributes to environmental damage.

In Australia, people who admitted to poaching（偷猎） thought it was much more prevalent in society than it really was, and had higher estimates than fishers who obeyed the law. They also believed others viewed poaching as socially acceptable; however, in reality, more than 90% of fishers held the opposite view. The false consensus effect has also shown up in studies examining support for nuclear energy and offshore wind farms.

Just as concepts from psychology can help explain some forms of environmental damage, so too can they help address it. For example, research shows people are more likely to litter in areas where there's already a-lot of trash scattered around; so making sure the ground around a bin is not covered in rubbish may help.

Factual information on how other people think and behave can be very powerful. Energy companies have substantially reduced energy consumption simply by showing people how their electricity use compares to their neighbors. Encouragingly, stimulating people's natural desire for status has also been successful in getting people to "go green to be seen", or to publicly buy eco-friendly products.

As the research evidence shows, social norms can be a powerful force in encouraging and popularizing environmentally friendly behaviors. Perhaps you can do your bit by sharing this article!
