A desert is a very dry land where there is hardly any rain. In the day, it can be so hot that you could fry an egg on the ground. But during the night it is sometimes so cold that water would turn into ice.

Many deserts are covered in sand. But some have mountains, rocks, or lakes that have dried up in the heat. The Great American Desert has cliffs（懸崖）that have been made into amazing and beautiful shapes by the wind. The Sahara Desert in Africa is mostly sand. The Australian Desert has red sand.

Sometimes it does not rain for a whole year in the desert. But there is water deep under the ground and some plants have roots that go very deep to find it. Other plants have roots that spread out（延伸） a long way so they can suck up the rain as soon as it falls.

One desert plant is the cactus, which has long, spreading roots. The cactus stores water inside its hard skin. This skin protects it from heat and cold.

Camels are a bit like cactus plants! They store water too—inside their bodies. They have special fur which protects them from the sun during the day and keeps them warm at night.

Some other animals live in deserts, too. They have to be very good at seeing and hearing because most of them only come out at night. This is why many desert animals have extra big eyes or ears.

A desert fox has bigger ears than a normal fox. A gerbil has huge eyes, so that it can see at night. It stays cool in the day by staying underground, like most desert animals.

   Some people live in the desert but they always make their homes near an oasis. An oasis is where water comes from an underground river. Near an oasis, people can grow lots of plants and keep animals.

Life is hard in the desert, for people, animals and plants. But desert people like to live there.

1. A desert is very dry because ________.

  A. it is sandy                                           B. there is so little rain 

  C. the wind is strong                                D. there is no water deep under the ground

2. What does the underlined phrase “suck up” in paragraph 3 mean ________?

  A. 圍堵                     B. 討好                C. 釋放              D. 吸收

3. Some desert animals have extra big eyes or ears because ________.

  A. the sunlight is too strong in the day               B. they need to see and hear well at night

  C. it is very cold at night                                   D. they store water in them

  4. Most desert animals stay cool in the day by ________.

     A. storing water inside their bodies            B. drinking water as much as they can

     C. staying underground                                  D. growing lots of plants

  5. Which of the following is true?

     A. Desert people like to live in the desert though life is hard.

  B. People in the desert usually fry eggs on the ground.

     C. Camels have special fur to store water.

     D. All the deserts are covered in sand.

   For better eyesight(視力), doctors advise limiting(限制) the hours of screen time and encourage having enough eye resting time.

   However, another study shows that sitting in front of computer or TV screens for long hours is not the only reason for myopia(近視). An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia.The research team found that there were less children who had myopia in Sydney than those in Singapore, even though they spent more time in front of computer and TV screens. The major finding is that children in Sydney spend longer hours on outdoor sports than those in Singapore.

   Indoor and outdoor sports both make the eyes pay attention to more distant(遠處的) objects, which stops the eyes from changing original shape. But outdoor sports may be better than indoor sports for myopia. Because natural light is good for eye growth and vitamin(維他命) D from the sunlight might be useful to it.Many doctors suggest that every child get its first eye test when he/she is about two and half years old, and even if his/her sight seems good enough. It is necessary for myopic(近視的) children to wear glasses to stop headaches, trouble reading and so on. It is also important that schools invite doctors to test their students’ eyes.

If that is not possible, school teachers should at least encourage parents and children to have regular eye examination and wear glasses. And parents should remember not only to limit the total screen time for their children, but also to encourage them to spend time outdoors.

1. What did the Australian research team study for?

       A. To find the reasons for myopia.

B. To find the ways to treat myopia.

C. To learn to choose right glasses.

D. To improve children’s eyesight.

2. Why are there fewer children with myopia in Sydney than those in Singapore?

A. Because the children in Sydney watch TV less.

B. Because the children in Sydney have more eye resting time.

C. Because the children in Sydney use computer less.

D. Because the children in Sydney do more outdoor sports.

3. What is good for eye growth according to the passage?

       A. Natural light.                                  B. Vitamin D.

       C. Natural light and Vitamin D.     D. The sun.

4. Which of the following is true?

A. Children should have eye tests as soon as they reach school age.

B. Looking more at distant objects can help the eyes keep their original shape.

C. Doing outdoor sports with no glasses is good for myopic children.

D. Children should limit their time in the sun to protect their eyes.

5. The passage mainly tells us          .

A. the children in Sydney spend more time in front of screens

B. the children in Singapore like outdoor sports

C. doing outdoor sports and limiting the hours of screen time are good for eyes

D. it’s important to test students’ eyes
