Liu Xu is a student from a middle school in Guangxi. Once he was riding home when a  robber (盜賊) suddenly jumped out from the roadside. He pulled Liu Xu off his bike and rode away. Liu Xu was scared, but he didn’t run after the robber. He found a telephone and called the police at 110.
“Safety is the first important in such a situation,” Liu said, remembering what his teacher had told him in his first aid class. “It is not safe to run after an adult who is stronger than you.”
Liu’s school has compulsory (必修的) first aid education. Students must take the class once a week.
Teenage safety has become a serious issue recently. According to a survey, about 16,000 teenagers die in accidents in China every year.
At Liu’s school the first aid classes are to “teach students skills how to protect and save  themselves in emergencies (緊急情況)”. Students there often learn by role-playing in first aid classes. For example, one student performed as a stranger knocking at a door. Another one stood inside the door and asked several questions before letting the “stranger” in. Then they changed roles and did it again. They learned a lot while having fun at role-playing.
The topics of the first aid classes are regularly updated (適時的). The students have learned skills for surviving in earthquakes. The teacher also taught the students not to go out at night. If someone tried to do bad things to them, they should quickly run into crowed place.
【小題1】Liu Xu’s _________ was robbed according to the passage.
A．moneyB．bikeC．backpackD．mobile phone

Expressions cover all parts of our life. They may be around your ears every day. You may know a lot of Chinese expressions that describe how you feel. Here are some English ones for your enjoyment.
Have Your Heart in Your Mouth
This expression means that you're really afraid or anxious about something. When your heart starts beating so much that you can feel a thumping(怦怦跳) in your throat, it may feel like you "have your heart in your mouth."
Have Butterflies in the Stomach
How did butterflies get in your stomach? Well, those really aren't butterflies in there. It is a way of describing those nervous feelings you might get before a test or a very important decision.
These stomach flutters (跳動) are normal and happen to many people. Some people believe having a few butterflies might even help you perform better.    
Sick as a Dog
If you've ever been very sick, you may have used this expression. Because dogs eat just about anything they find, they often get sick. So it's all right to describe someone who's not feeling well as being "sick as a dog".    
Under the Weather
When it's rainy all day outside, how would you feel? This expression comes from the idea that bad weather might hurt a person's health and mood(心情).

During the day, you spend a lot of time running, jumping, laughing, eating, and talking. You use up a lot of energy(能量) , and by the end of the day you're tired. Sleep gives your body a chance to rest.
But your brain (大腦)and body are not completely at rest during sleep. While you sleep, your mind may think of the things that happened during the day. It keeps the important things in mind as memories(記憶). It also thinks about things you were worrying about, and you may wake up with answers to some of your problems.
You also grow while you sleep. The thing called "human growth hormone (荷爾蒙)" in the body helps you grow during sleep. This growth hormone also helps the body to repair itself.
Sleep helps your body to conserve energy too. You use up a lot of energy during your daily activities. But when you sleep, your body temperature falls, and your "metabolism" (新陳代謝) slows down. You are still using some energy, but much less than when you are awake and active.
Have you ever stayed up past your bedtime? Did you have difficulty getting up the next morning? Maybe you had problems seeing clearly or you cannot think clearly. That was your body's way of saying, "I need sleep！" A lack ( 缺乏) of sleep can stop your body and mind from working correctly.

A．It helps people rest well.B．It helps repair the body.

One day, after I had given him his dinner, he started crying for mum.He was so young and really needed mum. So I dressed him, put on his shoes, carried him on my back and walked out. Soon he fell asleep. About half an hour later, I found that he had lost a shoe while sleeping. I took him off my back and put him down. I knew we needed to find that shoe, for our mother couldn’t afford new shoes. We had to go back to find it, so I told my brother to wait right there. A man heard it and stopped me just before I walked off. He asked me, “You are leaving your brother here to find the shoe? What would you do if he is not here when you return?” I did not know how to answer that question. He continued, “It’s OK if you can’t find the shoe, but it is not OK to lose your brother.” Then he sent us to mum’s workplace by taxi.
