Emergencies(紧急情况)don't happen very often. But when they do, you want to get help first. No one wants to spend time looking up the phone numbers.

In 1568, the Untied States government wanted one number that people could call for emergencies. They decided that 911 was easy to remember and people could dial it quickly. The very first 911 call was made on February 16, 1968. in Alibama. Today, 911 is used for emergencies in most parts of the United States and many parts of Canada.

Other countries may use other numbers. In Great Britain, it's 959. If you're not sure which emergency number is used in your area, check your phone book.

When to call

Never call 911 as a joke or just to see what might happen. The only time you should call 911

 阅读下列短文,从下面每题的A、B、C、D四个选项中选出最佳选项。

Spider monkeys are. New World primates(灵长类). They get their names because they have very long limbs(四肢)and tails, which make them look like spiders. They are often seen with their limbs on different branches.

Spider monkeys can be in tropical forests of Central and South America, from southern Mexico to Brazil. They are 35 to 66 centimeters long and weigh 13 to 26 pounds. They have long tails that they use to catch tree branches, kind of like a 5th hand.

Spider monkeys live in groups. One group usually has dozens of spider monkeys. They communicate with each other through screeches(尖叫声). A night, spider monkeys break off into smaller sleeping parties of about half a dozen or fewer. Unlike many other primates, males(雄性)stay together throughout their lives with the females. They leave their first groups to find another group.

When they go out to look for food, spider monkey groups take separate actions in order to avoid competition for it. They mainly eat fruit and nuts. They also eat other things like insects, honey, leaves, spiders and bird eggs. Spider monkeys actually play an important part in the spreading of seeds throughout the South American rain forests. Enemies that they need to keep an eye out for include animals like lions and crocodiles.

Spider monkeys are dying out. Woodcutting, which leads to the loss(丧失)of their natural living places, is playing a big role in their loss. These monkeys are also hunted for food, or to sell as pets. Spider monkeys are actually one of the most popular monkey pets around because of their look and their behavior. We must do something to protect them. After all, such good and interesting monkeys should live with humans for many years to come.

 阅读下列短文,从每小题所给的A、B、C、D四个选项中,选出最佳选项。

A tornado (龙卷风) is a kind of strong storm with air which moves in a circle quickly. They can move over 200 miles per hour and cause a lot of damage. As they move across the land, they can easily pick up cars, trucks, and even houses, and then throw them very far. It is important to find a safe place if a tornado gets close. 

A safe place could be a basement or the lowest floor. If you are in a home without a basement, try to find a first-floor bathroom or a small room without windows in the middle of your house. You should curl up (蜷缩) into a ball and cover your head and neck with your hands. 

But there are some people who actually want to get close to tornadoes. They are scientists who want to learn more about tornadoes. One of the best ways to do this is to get as close as possible to the tornado. They use special tools to measure (测量) what is happening in and around a tornado. 

One special tool is called a tornado probe (探测仪) . Inside the tornado probe, there are sensors (传感器) to measure wind speed, temperature, pressure, and direction. Some probes even have cameras, so the scientists can see and understand what it's like to be in a tornado.

To be able to get these measurements, the scientists have to get a tornado probe near or into a tornado. Scientists will try to guess where a tornado will go next. Then they drive to that location and put down the probe. If they do not guess correctly, they pick up their probe and r another place. If they are right, the tornado will go near or even right over the probe. Then they take all of the measurements from the probe and use them to predict where future tornadoes may form and travel. And they can give people some warning to keep away from a dangerous tornado.
