It is______ to predict the future of modern industry.

[ ]

Earthquakes are hard to predict. but do you know what to do before, during and after an earthquake? Here’s some advice:
Before an earthquake It’s necessary to prepare yourself and your family. All family members should know how to turn off gas, water and electricity and know useful telephone numbers(doctor, hospital, police, 119, etc.). Never put heavy things over beds.
During an earthquake It’s important for each of you to stay calm. If you are indoors, quickly move to a safe place in the room such as under a strong table. The purpose is to protect yourself from objects, stay away from windows, large mirrors, heavy furniture and so on. If you’re cooking, turn off the gas. If you’re outdoors, move to an open area like a playground. Move away from buildings, bridge and trees. If you are driving, stop the car as soon as possible, staying away from bridges and tall building. Stay in your car.
After an earthquake Once the shaking has stopped, DO NOT run out of the building at once. It’s better to wait and leave when it’s safe. Check around you and help the people who are in trouble. If your building is badly broken, leave it. If you smell of hear a gas, get everyone outside and open windows and doors. If you can do it safely, turn off the gas. Report it to the gas company.

A．People should know how to turn on gas.

B．People should now how to save water.

C．People shouldn’t put heavy boxes over beds.

小题5:You can learn _______after reading the passage.

A．what an earthquake is like	B．what to do to avoid an earthquake

Scientists who try to predict earthquakes have gotten some new helpers recently—animals.
　　That’s right, animals. Scientists have begun to understand what farmers have known for thousands of years. Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a Chinese quake in 1975, snakes awoke from their winter sleep early only to freeze to death in the cold air. Cows broke their halters (缰绳) and tried to escape. Chickens refused to enter their cage. All of this unusual behavior, as well as physical changes in the earth, warned Chinese scientists of the coming quake. They moved people away from the danger zone and saved thousands of lives.
　　One task for scientists today is to learn exactly which types of animal behavior predict quakes. It’s not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1977, for example, an Arabian horse became very nervous and tried to break out of his enclosure. The Australian horse next to him, however, remained perfectly calm. It’s also difficult at times to tell the difference between normal animal restlessness and “earthquake nerves”. A zoo keeper once called earthquake researchers to say that his cougar had been acting strangely. It turned out that the cat had an upset stomach.
　　A second task for scientists is to find out exactly what kind of warnings the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can sense tiny changes in air pressure, gravity, or the magnetism of Earth. This extra sense probably helps animals predict quakes.
　　A good example of this occurred with a group of dogs. They were shut in an area that was being shaken by a series of tiny earthquakes. (Several small quakes often come before or after a large one.) Before each quake a low booming sound was heard. Each boom caused the dogs to bark wildly. Then the dogs began to bark during a silent period. A scientist who was recording quakes looked at his machine. It was acting as though there were a loud noise too. The scientist realized that the dogs had reacted to a booming noise. They also sensed the tiny quake that followed it. The machine recorded both, though humans felt and heard nothing.
In this case there was a machine to monitor what the dogs were sensing. Many times, however, our machines record nothing extraordinary, even though animals know a quake is coming. The animals might be sensing something we measure but do not recognize as a warning. Discovering what animals sense, and learning how they know it is a danger signal, is a job for future scientists.
