Plans grow(46)in almost every part of the world. We see(47)such plants as flowers, glass, and tree nearly every day. Plants grow high on moutaintops, far in the oceans, and in many deserts and(48)polar regions
Without plants, there could be not life on earth. Man could not live without air of food and so he could not live without plants. The oxygen in the air we breathe comes from plants. The food we eat also comes from plants or from animals that eat plants. We build houses and make many(49)useful products from lumber cut from trees. (50) Much of our clothing is made from the fitbers of the cotton plants.
Scientists belive there are more than 350,000 species of plants, but no one knowns for(51)sure. Some of the smallest plants, called diatoms, can be seen only with a(52)microscope . A drop of the water may hould as many as 500 diatoms. The largest living things are the giant sequoia trees of California. Some of them stand more than 290 feet high and measure over 30 feet wide
Scientist(53)divide all living things into two main groups - plants and animals. It is usually easy to tell the two(54)apart . Almost all kinds of plants stay in one place, but nearly all species of animals move about under their own power. Most plants make their own food from air, sunglight, and water. Animals cannot make their own food. The basic units of all life, called cells, are also different in plants and animals. Most plants have thick wall that(55) contain a material called cellulost. Animal cells dl not have this material.
Chúng ta sống trong một thế giới năng động, và môi trường sống luôn luôn trải qua những thay đổi ở tất cả các cấp độ. Tuy nhiên, những thay đổi tự nhiên thường xảy ra ở tốc độ chậm để tác động đến từng loài có xu hướng nhỏ - ít nhất là trong ngắn hạn
Khi tốc độ thay đổi được tăng tốc đáng kể, có thể không có thời gian để các loài cá thể phản ứng với hoàn cảnh mới, và các hiệu ứng có thể là thảm họa. Tóm lại, đây là lý do khiến mất môi trường sống nhanh chóng được coi là nguyên nhân chính gây nguy hiểm cho loài, và không có lực lượng nào mạnh hơn trong vấn đề này so với con người. Ở một mức độ nào đó, mọi phần của trái đất đã bị ảnh hưởng bởi các hoạt động của con người, đặc biệt là trong thế kỷ qua. Điều này áp dụng trên hầu hết mọi quy mô, từ việc mất vi khuẩn trong đất đã từng hỗ trợ rừng nhiệt đới, đến sự tuyệt chủng của cá và các loài thủy sinh khác trong môi trường nước ngọt bị ô nhiễm, thay đổi khí hậu toàn cầu gây ra bởi việc thải khí nhà kính. Từ quan điểm của một đời người, những thay đổi như vậy có thể khó phát hiện và ảnh hưởng của chúng đối với từng loài có thể khó dự đoán. Nhưng bài học là đủ rõ ràng. Ví dụ, mặc dù nhiều quốc gia đã có kế hoạch trồng nhiều khu rừng nhiệt đới, chúng rất dễ bị phá hủy bởi vì các loại đất mà chúng phát triển rất nghèo trong các chất dinh dưỡng sẵn có. Nhiều thế kỷ có thể được yêu cầu mang lại một khu rừng bị cắt giảm hoặc bị đốt cháy trong không gian vài năm. Nhiều loài động vật và thực vật bị đe dọa nghiêm trọng trên thế giới sống trong các khu rừng như vậy, và chắc chắn rằng một số lượng lớn chúng sẽ biến mất nếu tỷ lệ mất rừng hiện tại tiếp tục. Môi trường sống trên thế giới là không thể thay đổi và tồn tại cố định.

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.

2. What threatens plants and animals most?

4. In paragraph 2, the word estimate is closest in meaning to
A. confirm B. calculate C. formulate D. participate
5. Why can animals and plants survive in the Sahara Desert?
