If a flood is likely in your area, you should:
Listen to the radio or watch television for information. If there is any possibility of a flash flood, move at once to higher ground.
If you have time to prepare, you should:
Make your home safe by bringing in outdoor furniture. Move necessary items to an upper floor.
If you have to leave your home right away, remember these tips:
Do not walk through moving water.
| A．Do not drive into flooded areas. |
| B．Do not wait for instructions to move. |
| C．20 cm depth of moving water can make you fall. |
| D．Turn off all pieces of electrical equipment. |
| E．Flash floods often have a dangerous wall of water. |

【推荐1】When we found him, he was a sorry sight. His clothes were torn, his hands bleeding. Before we reached him, we saw him fall. He lay a moment. Then he pulled himself to his feet, walked unsteadily (摇摆地) a few yards through the woods and fell again. After we got him out, we went back to find the gun that he had thrown down. His tracks showed that for two days he had circled in the forest, within 200 yards of the road. His senses were so dulled by fear and tiredness that he did not hear the cars going by or see the lights at night. We found him just in time.
This man, like others before him, had simply been frightened when he knew he was lost. What had been a near disaster might have turned out as only a pleasant walk, if he had made a few preparations before he stepped from the highway or off a known path (小径).
Whatever sense of direction that a man may have, it’s still largely a question of observation. A skilled woodsman always keeps an eye on his surroundings. He notes the shape of a mountain, the direction water flows through a swamp (沼泽), and the way a tree leans across a path. With these in mind, he is still likely to turn around many times, but he is seldom lost.
There are exceptions, of course, and once in a while a man does come across some strange problem that puts him into the “lost” situation. A rainstorm may catch him without a compass in his pocket. Darkness may find him in a rough area, where travel is dangerous without a light.
When this happens, the normal first reaction is the fear of being laughed at as a result of his poor knowledge in the woods. He may also be concerned about the inconvenience that he will cause his friends when he doesn’t show up. This false pride may lead him to keep on the move in a false effort to find his way against all difficulties.
The person who thinks ahead is seldom in great danger. He’ll be safe if he observes carefully, thinks ahead, and remains calm.
1. The writer suggested that if the man had not been found, ________.| A．he would have been shot by a gun | B．he would have become confused |

| A．he will worry about being laughed at |
| B．he will push himself to find his way out |
| C．he will feel sorry that he didn’t prepare well enough |
| D．he will feel it is convenient to ask for help from his friends |
| A．go into the woods by themselves | B．keep their head when they are in trouble |
| C．are frightened when they think they are lost | D．don’t know how to signal for help properly |
| A．A Man Lost in the Woods | B．Timely Rescue in the Woods |

【推荐3】Earthquakes happen without warning(前兆). They can happen any time of a day, at any point during the year. But don’t worry because most are so weak that they cannot be felt. Only a few big ones hurt people. However, it’s important to know what to do when an earthquake is happening．
Do NOT go outside. You could get injured from falling glass or parts of buildings. If you are outside, stay away from buildings and power lines (输电线).
Stay under a desk, table, or other strong furniture. Hold on to it. Or stay in a corner of the building. Cover your face and head with your arms and cover your mouth with a towel or clothing. Stay inside until shaking stops and it is safe to go outside.
Keep away from windows., pictures or advertisements on the wall or the building, and anything else that could fall and hurt you. Most people get injured by falling things during an earthquake, not by the shaking itself．
Also keep away from a fire. You could fall down and burn yourself on the fire.
If you are driving when an earthquake happens, stop the car if it’s safe. Stay inside your car until the earthquake stops, and don’t drive near bridges. Try not to stop by power lines or trees. These could fall and hurt you.

【推荐1】Some scientists have traced the increase in earthquakes to human activities, especially in areas not known for the presence of fault lines or past seismic (地震的) activity. The idea of humans causing earthquakes may seem strange at first. After all, you can run around your backyard and jump up and down as you want, and the ground isn’t going to start shaking. However, scientists have identified a variety of large scale human activities that can result in earthquakes.
Scientists have confirmed over 700 places where human activities have caused earthquakes over the last century. While many human-related earthquakes are small and don’t cause much damage, some of them can be serious and dangerous. In fact, scientists believe human activities have caused earthquakes with magnitudes as high as 7. 9 on the Richter scale.
Scientists believe that most human-related earthquakes are the result of mining. As companies drill deeper and deeper below the earth’s surface to get natural resources, holes left behind usually cause instability (不稳固) which leads to earthquakes. Another human activity leading to earthquakes is fracking (水力压裂) for oil and gas, including the high pressure waste water processing that usually goes with fracking. In this process, water, sand and chemicals are pressed underground under high pressure to break rocks to release natural resources.
Building large dams can also cause earthquakes. Many people died as a result of a big earthquake caused by millions of tons of water that had been collected in a reservoir after a large dam was built over a known fault line.
These are not the only human activities that can result in earthquakes, though. Scientists point out that earthquakes can also be caused by other human activities, such as construction of skyscrapers and nuclear explosions.
There is no doubt that human activities have contributed a lot to social and economic development, but for our own benefit, we humans had better not push nature too hard, or we will have to pay a price.
1. What does the underlined part “fault lines” in paragraph 1 probably refer to? .| A．Places with active human activities. | B．Places connected with natural balance. |
| C．Areas where natural resources are rich. | D．Areas where earthquakes tend to happen. |
| A．They break the balance of nature. | B．They destroy the stability of rocks. |
| C．They do much damage to the earth’s surface. | D．They use high pressure to get natural resources. |
| A．Objective. | B．Supportive. | C．Doubtful. | D．Responsible. |
| A．All the earthquakes are caused by humans. |
| B．Humans are responsible for certain earthquakes. |
| C．Nature punishes humans by means of earthquakes. |
| D．Much progress has been made on earthquake research. |
【推荐2】Check out the facts about the tsunami (海啸)and learn some interesting information related to these great walls of water that can cause so much destruction. Find out what causes tsunamis and read about some recent examples of tsunamis that have occurred around the globe.
Tsunamis are huge waves of water that are usually caused by earthquakes or volcanic eruptions (喷发).As a tsunami approaches the shore, water may move back from the coast. If it is shallow enough, water may be pulled back hundreds of metres. If you are on the shore and observe this phenomenon, you'll know that a tsunami is on the way.
Regions in tsunami danger zones often have warning systems in place to give people as much time to evacuate (撤出)as possible. When tsunamis hit shallow water (often near the coast), they slow down but increase in height.
An earthquake in the Indian Ocean off Indonesia in December 2004 caused a tsunami that killed over 200,000 people in 14 countries. In March 2011, the Tohoku earthquake off the eastern coast of Japan caused a tsunami that was a major factor in the death of over 15,000 people. The tsunami waves created by the 2011 Tohoku earthquake reached heights of over 40 metres in northern Japan, destroying coastal towns and causing a number of nuclear accidents.
The Japanese word "tsunami'' literally means "harbour wave''. Tsunamis are sometimes referred to as tidal waves but this term has fallen out of favour because tsunamis are not related to tides.
1. Which of the following shows a tsunami is around the corner?| A．An earthquake takes place. |
| B．The water near the shore is pulled back. |
