　　Nearly everyone agrees that money doesn't buy as much as it used to, no matter where you want to spend it. This is certainly true of the paper money that passes so quickly through one's hands. Inflation (通货膨胀) eats away at its buying power just as the steady appetite of waves chews at sand cliffs. But what about coins that seem to do very little except make purses and pockets untidy? Unlike notes, metal money becomes more valuable the longer it is held, especially if it is put away where it won't get scratched or worn. Why is this? One reason is that coins, being more durable (耐用的), fall more readily into a category for collections. Naturally, the rarer gold pieces must become more valuable as the price of this metal goes up.

    But, curiously, one of the rarest coins in the world is not made of gold, but of the relatively cheaper silver. In 1840, the United States mint struck 19, 570 silver dollars. That is what its records show. Today only six of this original number remain and these are unlikely ever to the auction market. So what happened to some 19, 564 large silver coins, not the easiest sort of things to lose? One of the more romantic theories is that they were part of the payment to Napoleon for the American territory then known as Louisiana. But they never reached France. Somewhere in the Gulf of Mexico, the ship transporting them was sunk, either by a storm or by pirates. The probable answer to the mystery is that they were melted down—since the silver value was greater than the actual value of the coin. What really happened to the rest will probably always remain a mystery. What .is known is that whoever can come up with one will find himself instantly rich.

Which animal has the fastest snapping jaw (颚)? If you're guessing a shark or perhaps a larger animal, you'll have to think smaller. The trap­jaw ant, which lives in Central and South America, moves its mouth parts at 35 to 63 meters per second. Another way to think about this is that the ant's jaws close at 125 to 233 kilometers per hour. That's 2, 300 times faster than the blink of an eye.

Scientists were able to measure the amazing jaw speed using high­speed video techniques. Sheila Patek, a biologist, says the key is that the jaws have a springy (有弹性的) system, which is critical in getting explosive (爆发性的) speeds.

Consider a bow and arrow. If you try to throw an arrow with your arm, it won't go very far. If you use a bow, elastic energy stored in the bow is released almost instantly when you release the arrow with your finger or a latch. The combination of the springy bow and latch mechanism is what makes the arrow zoom through the air.

Maybe even more amazing than how fast these ants grab food or even enemies is how they use this same energy to move. As the ant closes its jaws, it uses them to push off the ground—all faster than the eye can see without slow motion video. A snap of the jaw can send an ant up to 8.3 centimeters into the air. That's like someone who is 1.7 meters jumping 13 meters high! Not only can they quickly escape from enemies, but often a group of ants will start jumping all at once. It would be hard for their enemies to grab just one.

People have suspected the ants used their jaws to jump for over a century, but could only prove it with today's modern video equipment.

1.The fast speed of the trap­jaw ant's jaw lies in ________.

A．its light body

B．its springy system

C．its living environment

D．the length of its jaw

2.The passage uses “a bow and arrow” as an example to show ________.

A．how an arrow gets so much energy to fly

B．why the trap­jaw ants have springy system

C．why the trap­jaw ants jaws move so fast

D．how a bow and arrow works

3.Which of the following may amaze the scientists most?

A．How high the ants can leap by using their jaws.

B．How quickly the trap­jaw ants can move on the ground.

C．How wonderfully the springy system in the trap­jaw ants' jaws works.

D．How quickly the trap­jaw ants can grab food or enemies.

4.According to the passage, the trap­jaw ants' jaws keep them safe because ________.

A．they can catch their enemies easily with their jaws

B．their jaws make them difficult to recognize

C．their jaws help them find food easily

D．their jaws help them escape from their enemies

 

Cheating can happen in a lot of different ways. When people cheat, it’s not fair to other people, like the kids who studied for the test or who were the true winners of a game.

Many people like the action of cheating. It makes difficult things seem easy, like getting all the right answers on the test. But it doesn’t solve the problem of not knowing the material and it won’t help on the next test --- unless the person cheats again.

Some people lose respect for cheaters and think less of them. The cheaters themselves may feel bad because they know they are not really earning that good grade. And, if they get caught cheating, they will be in trouble at school, and maybe at home, too.

Some kids cheat because they’re busy or lazy and they want to get good grades without spending the time studying. Other kids might feel like they can’t pass the test without cheating. Even when there seems to be a “good reason” for cheating, cheating isn’t a good idea.

If you were sick or upset about something the night before and couldn’t study, it would be better to talk with the teacher about this. And if you don’t have enough time to study for a test because of swim practice, you need to talk with your parents about how to balance swimming and school.

A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions(解决办法) together. Talking about these problems and working them out will feel better than cheating.

1.The author thinks that when kids cheat in class, _______.

A．it is unfair to other people

B．it does harm to their heath

C．teachers should punish them

D．teachers shouldn’t stop them at once

2.Some students like cheating mainly because_________.

A．the material in the test is very difficult

B．they want to do better than the others

C．cheating can make hard things seem very easy

D．they have little time to study their lessons

3.We can learn from the passage______.

A．cheaters are often thought highly of

B．people show no respect for those who cheat

C．parents whose kids cheat are often in trouble

D．kids cheat in the test because of swim practice

4.In the passage those cheaters are advised to_______.

A．spend more time on school than on sports

B．find good solutions instead of cheating

C．try hard to be intelligent rather than lazy

D．ask their classmates for good methods of study
