Because earthquakes happen without warning, it’s important to take steps now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies(急需品) for your home, work place, and car.
1.Water
A person needs at least 1/2 gallon(加侖,容量單位) of water daily just for drinking. Store at least 1 gallon of water per(每一個) person per day and be prepared for a 72 hour period. It is suggested that you buy bottled water. Keep bottled water in its original container(容器) and do not open it until you need to use it. Also, do check the “use by” date.
2.Food
It’s always a practical idea to keep a supply of non perishable(不易腐爛的) food on hand. Have an enough supply of canned(灌裝的) food, powdered milk(奶粉), dried fruits, non salted nuts and canned juices for at least 72 hours.
3.Flashlights(手電筒) and spare batteries(備用電池)
Keep a flashlight beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks(泄漏).
Prepare a battery powered(裝電池的) radio and spare batteries. Most telephones will be out of order(發(fā)生故障), so radios will be your best source of information.
4.Clothes
If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.
根據(jù)短文內(nèi)容,選擇正確答案(10分)
小題1:Why should people prepare themselves for an earthquake?
A、Because earthquakes can be known before they happen.
B、Because earthquakes take place without warning.

According to a new Ministry of Education (教育部) survey, student safety has become a big problem. Nearly 50 percent of students say they are worried about robbery on the way to and from school. Now in many big cities in China, some school has taught an unusual lesson: self– protection. Students like this lesson as there are no exams or boring classes. And they can learn how to save lives and know how to stop danger before it really happens.
Chen Haoyu, a teacher at Beijing No.25 Middle School and a self–protection expert, gives young students advice on how to deal with danger.

On the first day of school our professor introduced himself and asked us to get to know someone we didn’t know. I stood up to look around when a gentle hand touched my shoulder. “Hi, girl! My name is Rose, I’m 87 years old.”
“Why are you in college at such a young age?” I asked jokingly.
“I always dreamed of having a college education and now I’m getting one!”she replied.  Rose became a college symbol(象征) this year and she easily on her from the other students.
At the end of the term we invited Rose to speak at our football party. I’ll never forget what she taught us.

“There is a huge difference between growing older and growing up. If you are nineteen years old and lie in bed for one full year and don’t do anything, you will turn 20 years older. If I am 87 years old, and stay in bed for a year, and never do anything, I will turn 88. Anybody can grow older. But every minute counts for young men,” she added.
