Deep in the forest of southeastern Mexico, scientists found a surprise. They found an ancient pyramid. There were colorful murals (壁画)in it. A mural is a painting on a wall. Those murals are helping scientists unlock a mystery about people who lived in ancient times.

    The murals are about 1,350 years old. That's more than five times older than the United States. Scientists say the paintings belonged to the Mayas. That was a group of Native American people. They lived many years ago in what is now Mexico and Central America.

    Scientists are excited about the discovery because they don't know much about the Mayas' daily life, explains Michael Coe, an expert on the Mayas. The paintings show how the Mayas worked, shopped and dined. One mural shows a man drinking from a bowl. Another shows a woman selling food to a crowd of people.

    "Mostly we get the murals that show gods and kings, never anything about the daily life," Coe said. "This is like walking into a Maya supermarket." So far, scientists have found more than 30 murals in the pyramid. They are not sure why the Mayas created them. The experts hope to learn more as they continue their search.

    "We never had anything like this before," said Coe. "These are really special murals."

    Scientists learned a lot about the Mayas from the murals. The Mayas were known for more than paintings. Now the murals tell us some fun facts about the Mayan way of life.

    The Mayas lived in what is now Central and North America. Today the area includes parts of Mexico, Belize, Guatemala, and Honduras.

    The Mayas invented a type of Maths. They also created a type of writing that used symbols or pictures. Mayas used bark (树皮)to make books.

    The Mayas often ate com and used it to make other foods. They grew many crops (庄稼), including beans and sweet potatoes.

    In many English homes people eat four meals a day: breakfast, lunch, tea and dinner.

    People have breakfast at any time from seven to nine in the morning. They eat porridge, eggs or bread. English people drink tea or coffee at breakfast. Lunch comes at one o'clock. Afternoon tea is from four to five in the afternoon and dinner is about half past seven. First they have soups, and then they have meat or fish with vegetables. After that they eat some other things, like bananas, apples or oranges. But not all English people eat like that. Some of them have their dinner in the middle of the day. Their meals are breakfast, dinner, tea and supper and all these meals are very necessary.

①Most people who move to a foreign country may experience a period of time when they feel very homesick and have a lot of stress. This feeling is often called "culture shock (文化冲击)". It is important to understand it and learn how to deal with it if you want to adapt successfully to your new home's culture.

②There are four stages that you will experience after you move to a foreign country. The first stage is usually referred to as the "excitement" stage. When arriving in a new environment, you'll be interested in the new culture; everything will seem exciting and everyone will seem friendly.

③But it won't be long before you move from the "excitement" stage to the second stage. The excitement you felt before changes to stress. It seems that everything is difficult. The language is hard to learn, friends are difficult to make, and even simple things like shopping have become a challenge. It is at this "stress" stage that you are likely to feel worried and homesick. This is the stage which is referred to as "culture shock".

④However, culture shock doesn't last for very long. If you are one of those who solve it successfully, you'll move to the "recovery" stage. At this stage, you start to understand and accept the way things are done and the way people behave in your new environment.

⑤The last stage is the "home" stage. This is the stage when you start to feel at home in the new culture. You start to learn from your new home and to like something of the new culture better than those of your own culture.

⑥Culture shock is normal. Everyone in a new situation will go through some form of it. Continue to be brave! And overcoming culture shock will be a piece of cake.

This famous poem（诗）, Happy Rain on a Spring Night, was written by Du Fu（712—770, the Tang Dynasty）when he was living and farming in Chengdu. His farming experience taught him to be thankful（感谢）to nature and it is shown in this poem. 

The very first word, "good", shows the poet's joy and love for the spring rain. The rain is good because it "knows" the proper time to come. Here the poet uses personification（拟人）, as if the rain was smart enough to come in time for the farmers' busy season. 

When the rain comes, it appears during the night without making any noise. Unlike the summer storms, the spring rain finishes its task without being known. 

In the third couplet（对句）, the poet describes a peaceful scene to us. In the night sky, the clouds look dark and heavy. It's a sign that there will be enough rain during the night. The light from the boat makes the dark scene a bit livelier. 

Lastly, the poet starts to imagine. Tomorrow morning, he thinks, the city of Chengdu will become beautiful when all of the flowers bloom after the rain.
