A.
Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons from his

experiences. He always told me, “You should have goals like climbing the mountain.” Without the mountain-climbing that we both enjoyed, we couldn’t have enough time to spend together because my father was very busy. I really got a lot from the mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience.
Once we climbed a very high mountain. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the birds’ singing. But as time passed, I got a pain in both of my legs. I wanted to quit climbing, but my father said to me, “You can always see a beautiful sky at the top of the mountain, but you can’t see it before you reach the top. Only there can you see all of the nice things, which is just like your life.” At that time, I was too young to understand his words. But later after that, I got to know the meaning of hope in life. I found myself standing at the top of the mountain, and the sky was as clear as crystal. 1. The passage tells us that mountain-climbing was ______ for the father and the son. A. hard B. enjoyable C. painful D. comfortable 2. The underlined word “crystal” in the passage means _______.
A. 岩石 B. 火焰 C. 水晶 D.寒冰
3. Which of the following is the closest in meaning to the father’s words in the second paragraph? A. You will get all you need at the top of the mountain. B. The sky is always as clear as crystal. C. You can find life is full of nice things. D. Never give up half-way. 4. We can infer(推断) from the last paragraph that ______.
A. the writer was very successful in his life B. the writer reached the top of the mountain C. though the writer was young, he could understand his father D. the writer used to stop half-way when he climbed the mountain 5. The best title for the passage is ______.
A. Reaching the top of the Mountain B. Standing at the top of the Mountain C. Conversations between Father and Son D. How to get to the Top of the Mountain
B.
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 for your home, workplace, and car.
1. Water.
A person needs at least 1/2 gallon of water daily just for drinking. Store at least 1 gallon of water per 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 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(不易腐烂的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Flashlights(手电筒) and spare batteries.
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.
Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, 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.
6. Why should people prepare themselves for an earthquake?
A. Because earthquakes can be known before they happen. B. Because earthquakes take place without warning. C. Because earthquakes usually take place in the neighborhood. D. Because it’s people’s daily work to prepare the earthquakes.

Such kinds of pollution as water pollution, air pollution and sound pollution are very common (常见的) to us, and people are doing something to reduce (减少) the environmental pollution. But do you know a kind of pollution called electricity pollution?
Recently, a newspaper reported that most teachers and students in a school suffer from headaches, tiredness and sleepiness. At last they found out the reason. Some areas beside the school were under construction. There was a strong magnetic field (磁场) on the road with high-voltage (高压) lines. The magnetic field could cause electrical discharge phenomena (放电现象). That led to a chemical reaction (化学反应), so human health was in danger in such an environment.
At present, experts are trying their best to find out a solution (解决办法) to this problem. 11. Which of the following is not common to us according to the passage.
