A lovely rabbit, a cute hamster, some colourful fish, a strange-looking turtle or a snake...What kind of pet would you like? Lots of kids love animals and dream of having a pet.

    But not every family can have a pet. So, in many Western countries such as America, Britain and Australia, primary and middle school classes have their own pets. Looking after a pet is not as easy as you may think! Fish and turtles need clean water and the right food. Hamsters and rabbits need fresh vegetables and a warm place to sleep. Even little mice need good care! What would you feed a pet mouse? How about snakes?

    Class pets teach kids about nature and being responsible. Sometimes the pets have babies. It's very exciting but it also means having more animals to take care of!

    Students take turns to take care of their class pets. Every week the pets have a new “mum and dad” to look after them.

    You may want to know what happens to the class pets during school holidays. At the end of term, the teacher chooses a responsible student. This lucky student keeps the pets at his or her home for the holidays.

    Notes:

1) hamster n. 仓鼠   2) turtle n. 乌龟   3) responsible adj. 负责任的   4) choose v. 选择

    Recently, one new disease NCP (新型冠状病毒肺炎) broke {#blank#}1{#/blank#} in Wuhan. It has spread to other countries, {#blank#}2{#/blank#} the United States and Japan. Local government is trying to do {#blank#}3{#/blank#} useful to stop the further development of this disease. In order {#blank#}4{#/blank#} (control) the spread of the disease, Huoshenshan Hospital was set up in Wuhan. It {#blank#}5{#/blank#} (build) in just ten days. It is used to treat patients infected with the NCP.

    More than 7,500 workers and around 1,000 trucks and large pieces of machinery have been working at the Huoshenshan Hospital site {#blank#}6{#/blank#} and night. Around 400 rooms in the hospital have already been finished so far. The project {#blank#}7{#/blank#} on January 25 and finished on February 2. And 1,400 doctors began to treat patients in Huoshenshan Hospital there are 1,000 beds for {#blank#}8{#/blank#} in Huoshenshan Hospital. China also built a {#blank#}9{#/blank#} (two) hospital in Wuhan for treating the patients, with1, 600 beds.

    Leishenshan Hospital was completed on February 5. The hospital reduced the stress resulting from the increasing number of patients. This played an important role in {#blank#}10{#/blank#} against the NCP.

    In traditional Chinese medicine, food is divided (划分) into two types; hot and cold. Both kinds of food affect (影响) your body {#blank#}1{#/blank#} different ways, So, having 57. {#blank#}2{#/blank#} balanced diet is safe and {#blank#}3{#/blank#} (health) for your body.

    Some examples of hot food {#blank#}4{#/blank#} (be) berries, mutton, and ginger (生姜) . If you eat too much of them, {#blank#}5{#/blank#} (certainly) things might happen to your body. You may start to sweat a lot and feel pain in your back, or even grow gray hair! If these things happen to you, you should avoid (避免) spicy food, coffee, or sugar.

    On  {#blank#}6{#/blank#} other hand, too much cold food like tomatoes and potatoes can also cause problems. It may make your hands and  {#blank#}7{#/blank#} (foot) cold. It also makes your body temperature lower.

    Besides what we eat, {#blank#}8{#/blank#} we eat is also important. You should always sit down and chew (咀嚼) carefully. Don't make {#blank#}9{#/blank#} (you) busy with other things, such as watching TV or {#blank#}10{#/blank#} (read) a newspaper. Finally, it's best to eat three meals a day at regular times.

Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed.

Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.

No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.

Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don't have to.
