IX. Đọc đoạn văn và trả lời câu hỏi :

The Sahara Desert is the world’s largest hot desert. The Sahara is in North Africa and is as large as the United States. Many people think that an area like this has no animals or plant life, but they are incorrect. In fact, the Sahara Desert has many different ‘ecoregions’. Each ecoregion has different plants and animals living there. The biggest ecoregion is called ‘Sahara Desert ecoregion’. In this area, the climate is extremely dry and extremely hot. The landscape is sandy and dusty with many high dunes.

Because the Sahara Desert ecoregion is so hot and dry, there are very few plants and animals. Scientists estimate that there are only 500 species of plants. This is not very much when thinking of how enormous the region is. These plants include acacia trees, plants, spiny shrubs, and grasses. The Sahara is also home to 70 species of mammals. Twenty of these are large mammals. There are about 90 species of birds and around 100 reptiles.

The biggest threat to plants and animals in this environment is drying up. Because of this, plants have ability to recover their health after their leaves have dried out completely. Animals can lose 30-60% of their body mass and still survive. Most animals do not get their water from drinking like other ecosystem. Instead, they have adapted to get their water through metabolic processes. This is why they can survive in a place like Sahara Desert ecosystem.

 Although the United States is a large country with many people, the language is almost the same wherever one goes. There are two reasons for this. One is that people move around a great deal in the United States. A man may grow up in one part of the country, go to college in another part, find work
in another place, and marry a girl from still another part of the country. Railroads, airplanes, cars and highways make it easy to travel in America. Many large companies have branches in different areas of
the country and transfer their workers from one branch to another. The second important factor is public communication. Movies, radio, and television all have a standard way of speech, and almost everyone in the United States hears it. There are, however, some words and expressions more common
in one part of the country than in others. Throughout the history of the United States, large groups of
immigrants have come to make their homes and they give new words to the language.
