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.

Earth is losing wildlife at a faster rate than at any time in history. This is according to the new Living Planet Report from the World Wildlife Fund. The report says the global wildlife population shrank by 60 per cent between 1970 and 2014. The WWF warned that: Earth is losing biodiversity at a rate seen only during mass extinctions. Researchers state that most of the decline in our animal population is because of exploding human consumption. There are more and more humans on this planet. We a...

Earth is losing wildlife at a faster rate than at any time in history. This is according to the new "Living Planet Report" from the World Wildlife Fund. The report says the global wildlife population shrank by 60 per cent between 1970 and 2014. The WWF warned that: "Earth is losing biodiversity at a rate seen only during mass extinctions." Researchers state that most of the decline in our animal population is because of "exploding human consumption". There are more and more humans on this planet. We are eating more, overfishing, cutting down trees for beef production, consuming more, and using more energy and natural resources. This has resulted in a massive loss of habitat for animals.The report estimates that only a quarter of the world's land has been untouched by humans. This means human activity has greatly affected animals on three-quarters of Earth's surface. Researchers tracked more than 4,000 species of mammals, birds, reptiles, fish and amphibians. They say the loss of animal life is worst in South and Central America. These regions saw an 89 per cent loss in the population of vertebrates in the past four decades. The WWF wrote: "The astonishing decline in wildlife population...is a [depressing] reminder, and perhaps the ultimate indicator, of the pressure we [put] on the planet." It warned: "We can be the generation that had its chance and failed to act; that let Earth slip away."

There has long been speculation concerning about the possibility of life and liquid water on Mars . However , the planet's thin atmosphere prevents water from accumulating for any time over significant portions of the planet . Some evidences of the planet's surface suggest the presence of liquid water at some point in history , but scientists think this water would be too salty or acidic to support life as we know it . Futhermore , fierce solar winds and poor heat transfer across its surface would make sustained life virtually impossible . There is compelling evidence , however , that Mars was once much more habitable to life than it is today .

There are 10 mistakes in the following passage. Identify the mistakes and write the corrections in the corresponding numbered boxes.
Stress is often called the(the -->a) 21st century illness, but it has always been with us perhaps with different names. Those days we often consider stress is necessary evil of modern life. However, stress is not negetive and without it we will certainly not enjoy some of the highpoints in life just as the anticipation before a date or the tension leading up to an important match. All these situations produce stress, but if you can control it and not the other way round you will feel stimulated, not worn out. Like these situations, which are generally positive but easier to deal with, sitting in a train that is late, being struck in a traffic jam, working to a tight deadline is much harder to manage and control. Stress is now recognized as a nedical problem and as a significant factor in causing coronary heart disease, high blooded pressure and high cholesterol count. The fact is that patients are often willing to admit to stress problems because they feel they are a form of society failure and it is important that symptoms should be identified in order to avoid unnecessary sufferings. So why should we be looking out for as danger singals? Some common signs of stress are increased tiredness, irritability and the inability to solve certain situations.

There are nine planets in our solar system. These planets each have their atmosphere and environmental conditions. Scientists have been trying to research other planets to see if it is possible for life to exist on the other eight own bodies in space.
Mercury and Pluto are probably the most difficult to research because of their position in the solar system. Mercury is so close to the sun that with our current technology a space shuttle would burn up before it even reached its atmosphere. Pluto is so far away that some scientists believe that it may not even be a planot but a large asteroid or comet. A space shuttle can not trave that far away because it is so far away from the sun that it would freeze.
Many scientists also believe that our solar system is not alone in the uni- with us. It is difficult to know if there is life present elaewhere in the universe. for many years to come. yerse. Many believe there are several other systems that share the uhiverse .The universe is a complex structure of space that may continue to be a mysterey for many years to come
32. There are nine planets in our solar system, besides Earth.
33. It is difficult to study the planet Mercury because it is very close to the sun.
