Disasters happen all the time somewhere in the world. Are you ready if one hits your neighborhood next week? Find out what you need to do now before it is too late. Let’s take an earthquake for example.
During an earthquake, get under a strong object like the kitchen table. Don’t leave the building during the shaking, or you might be hurt by falling objects from the outside of the building.
When you are in bed during the night and an earthquake happens，simply roll off the bed. There will be a safe void around the bed.
If you are watching TV and you cannot easily run away by getting out through the door or window, then lie down and curl up(蜷伏) next to a sofa, or a large chair.
Never go to the stairs. The stairs are likely part of the building to be broken. Even if the stairs are not destroyed by the earthquake，they may fall down later when people run down.
Try to get into an open area away from trees，buildings，walls，advertisement boards and power lines if you are outdoors.
If you are driving when an earthquake suddenly happens，just stay in your car until the shaking ends. However, if the footbridge falls and breaks your car，get out of it and sit or lie next to it. All the broken cars have voids 3 feet high next to it.
小题1: What should you do if you are in a building when an earthquake happens?

A．Rush out quickly	B．Sit in the kitchen
C．Stay below strong objects	D．Go down the stairs

小题2:The underlined word “void” in Paragraph 3 means“_______”.

A．space

B．seat

C．distance

D．sign

小题3: When you are outdoors during an earthquake，you should go to _______.

小题4: If you are inside a car when there is a sudden earthquake，you should _______.

A．get out of it

B．keep inside it

C．move away fast

D．stay under the footbridge

Animals Can Sense Natural Disasters
Among the dead in South Asia’ s tsunami（海啸）were many tourists at Sri Lanka’ s national wildlife park at Yala. But very few of the park’s animals — elephants, buffaloes, monkeys and wild cats — appear to have died. There are theories that animals can sense natural disasters and run away to safety.
First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater burst produced sound waves known as infrasound（次声）. Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.
A second early warning sign the animals might have sensed is ground vibration（震动）. The great quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves moving on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached Sri Lanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yala might have felt the Rayleigh waves and then run to higher ground.
But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints（关节）, which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears.
小题1:Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?

A．Because human beings cannot hear the infrasonic sound.

B．Because the animals were staying at a higher place in the park.

C．Because the animals were able to run much faster than human beings.

D．Because the animals might have picked up the danger signals and ran away.

小题2:Which of the statements about “Rayleigh waves” is true?

A．Rayleigh waves can be felt both by animals and human beings.

B．Rayleigh waves, just like infrasonic sound, can only be felt by animals.

C．Rayleigh waves are vibrational waves that usually cause quakes or tsunamis.

D．Rayleigh waves move on the ocean surface at a speed ten times that of sound waves.

小题3:According to the passage, which of the statement is true?

A．We can’t feel the infrasound so we can’t be informed of the danger.

B．We ignore the information of tsunami’s coming even though we can also get it.

C．We were so busy on our minds that we feel neither infrasound nor Rayleigh waves.

D．We can feel Rayleigh waves and infrasound so we can escape the danger like animals.

When TV news programs report wars or disasters, the editors rarely use the most horrifying pictures of dead or wounded victims because they don’t want to upset their viewers. Even so, viewers are usually warned in advance that they may find some of these scenes disturbing, so they can look away if they choose. But the men and women whose job is to record those scenes－the TV cameramen－have no such choice. It is their duty to witness the horrors of the world and record them, no matter how terrible and unpleasant they may be. Consequently, it is one of the most dangerous, exposed and emotionally taxing jobs the world has to offer.
Today, the demand for their work is rising. The explosion of satellite broadcasting and 24-hour news in recent years has created an almost insatiable (贪得无厌的) demand for TV information. But major broadcasters and the TV news agencies—such as Reuters and WTN－have never had enough staff to meet the worldwide demand for up-to-date pictures, so increasingly they turn to “freelance” TV cameramen.
These freelance cameramen are independent operators tied to no particular organization. They will work for any company which hires them, be it for just a few hours or for several weeks in a war zone. But if the freelance cameraman is injured in the course of the job, the TV company is not responsible for him. The freelancer must survive on his own.
TV will always need hard, vivid moving pictures which are fresh, but these companies feel uncomfortable with large numbers of employees on their books, explains Nick Growing, once foreign editor for Britain Channel 4 News and now a BBC news presenter.
By hiring freelancers, they can buy in the skills they need only when they need them. It also enables them to contract out the risk, he says.
小题1:TV news agencies turn to freelance cameramen in order to .

A．save expense and avoid risks

B．get free and useful pictures

C．get first-hand information and pictures

D．satisfy the greed of the freelance cameramen

小题2:We can infer from the passage that the freelance cameramen .

A．have to take a lot of risks in the course of work

B．are tied to many TV news agencies

C．have better skills than other cameramen

D．need to contract out risks of work for TV companies

小题3:According to this passage, some major broadcasters and TV news agencies .
A. have employed enough cameramen
B. are not willing to employ many cameramen
C. are very mean to freelancers
C. are responsible for the freelancer if he is injured
小题4:The author of this passage shows his the freelance cameramen.

A．sympathy to

B．respect for
