There is little rain in desert. Because deserts are so dry, they have no “quilt” to help stop the soil from going away. As a result, they may get very hot during the day with the sun shining, but don’t hold the heat overnight. Many deserts can quickly get cold once the sun goes down. Some deserts can reach temperatures of over 100 degrees F during the day and then drop below freezing (32 degrees F) during the night.
The largest hot and dry desert in the world is the Sahara Desert in Northern Africa. The Sahara is a sandy desert with great sand hills. It covers over 3 million square miles of Africa. Other large deserts include the Arabian Desert in the Middle East, the Gobi Desert in Northern China and Mongolia, and Kalahari Desert in Africa.
Animals that live in the desert are also used to needing little water. Many get all the water they need from the food they eat. Other animals keep water that they can use later. The camel stores up fat in its hump while other animals keep something they need in their tails.
Only certain types of plants can live in the terrible environment of the desert. You won’t see a lot of tall trees in the desert. Most plants have a way to keep water in their leaves, or trunks so they can live a long time without water.
Now deserts cover around 20% of the world’s land, but they are growing. This is called desertification and is caused by different reasons including human activities. The Sahara Desert is growing larger and larger each year. What should we do with it ?
1.How is the weather during the night in the desert?
A. Hot. B. Cold.
C. Cool. D. Sunny.
2.Where does the camel store up fat?
A. In its hump. B. In its stomach.
C. In its tail. D. In its body.
3.Why won't we see a lot of tall trees in the desert?
A. Because of few people there. B. Because of the sun shining.
C. Because of the terrible environment. D. Because there are no trees there.
4.How much of the land do deserts cover in the world?
A. One fifth. B. Less than 10%.
C. Two fifths. D. Three fourths.

Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive if the rain is spread throughout the year. If it falls within one or two months and the rest of the year is dry, those plants may die and a desert may form.
Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.
There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay under a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing –-very, very slowly ---as these forces of nature continue to work on the rock.
Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted to life in the desert. During the heat of the day a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.
1.Many plants may survive in deserts when___________.
A. it is dry all the year round

C. there is little rain in a year
D. the rain is spread out in a year
2.Sand dunes are formed when____________.
A. sand piles up little by little
B. there is plenty of rain in a year
C. the sea has dried up over the years
D. pieces of rock get smaller
3.The underlined sentence in the third paragraph probably means that in a desert there is_____.
A. too much sand
B. more sand than before
C. nothing except sand
D. something else besides sand
4.It can be learned from the text that in a desert____________.
A. there is no rainfall throughout the year

C. all sand dunes are a few feet high
D. rocks are worn away only by wind and heat

When we hear the word “pyramid”(金字塔) there is little doubt that Egypt(埃及) and the desert come to mind. Did you know, however, that continents and oceans away — in what is today Central America and Mexico — people also built pyramids? While they look somewhat different from the ones we see in Egypt, they also were built with great skill.
The pyramids of Central America were built by the Mayan(玛雅) and Aztec(阿芝台克) peoples, as well as other smaller groups. Both Mayan and Aztec cultures built pyramids for their gods. They thought that building higher pyramids would allow them to get close to heaven. These cultures believed that the gods were found in nature. One of the most important gods was the sun. Many of the pyramids were for their sun god. At the top of the pyramids they built temples to make the gods happier. However, pyramids were not used only for their gods.
Before Europeans came to the area in the 1500s, many of the cultures of the Americas, such as the Mayan and Aztec, had much knowledge about mathematics and astrology. They thought that the night sky could be used as a mirror to explain many aspects of life, which is the reason why they studied it carefully. The temples on top of the pyramids were also used as places for watching the skies. The Mayans had a solid understanding of the movement of stars and planets. This helped them understand the seasons. They were the first to create a 365-day calendar.
1.Why did they build pyramids?
A. For their king. B. For themselves.
C. For their gods and to study the sky. D. For the moon.
2.Which of the following sentences is not true?
A. Before Europeans came to the area, the Mayans and Aztecs had no knowledge about mathematics and astrology.
B. Building higher pyramids would allow the Mayans and Aztecs to get close to heaven.
C. Many of the pyramids were for the sun god.
D. The Mayan and Aztec pyramids built look somewhat different from the ones built in Egypt.
3.Where did people build pyramids besides Egypt ?
A. In Central America. B. In Japan. C. In Egypt. D. Not mentioned.
4.Where can you find the passage?
A. Newspaper. B. Advertisement. C. Novel. D. Magazine.
