Imagine the situation. You are driving along a desert or on a mountain. You have no idea where you are. You passed the last house two hours ago. Then your car breaks down. It is night and it is cold. You have no mobile phone. What do you do? Well, next time take a GPS with you. This invention may be able to help you. It is a device(装置) which uses satellites (卫星) to find the user’s position(位置). It can find your position to within 20 metres. A GPS cannot start your car, but at least you will know where you are.
GPS, which means Global Positioning System, is a small radio receiver. It looks like a mobile phone. You can hold it in your hand, or put in your pocket. It is sometimes put into a watch or a telephone. We also find GPS devices in cars, planes, or boats. Some of these devices have electronic maps, so you know where you are. For example, in a city they can tell you the name of the street.
There are three parts to the Global Positioning System. The first part is the receiver. You can hold it in your hand, or have it fixed into your car, plane, etc. The second part is a group of satellites orbiting the Earth. The receiver contacts at least four of the satellites and calculates(计算) its position. The third part of the system is a network of ground stations. They are all over the world. They control the satellites and make sure they are working well.
Some people think that in the future the GPS will be as common as the mobile. They are becoming cheaper and more and more accurate(精确的). There are also new uses for the GPS. Perhaps they will become like watches. Everyone will have one and you will never be lost again.
小题1:According to the passage, with the help of the GPS, people __________.
| A．can’t be lost in a new city |
| B．can’t find their way in different countries |
| C．can learn about the culture of an unknown place |
| D．can spend the least time getting to another place |
| A．there are three parts to the GPS |
| B．a GPS can’t be put into a watch |
| C．a GPS can help you start your car |
| D．the GPS are becoming more and more expensive |
| A．Receivers | B．GPS devices | C．Satellites | D．Ground stations |
| A．the history of the GPS | B．the introduction of the GPS |
| C．the shape of the GPS | D．the three parts of the GPS |
| A．All GPS devices have electronic maps. |
| B．People in many countries will use the GPS for free. |
| C．The receiver of the GPS contacts at least five of the satellites. |
| D．The GPS will become more and more common in everyday life. |
The ears and brain have an Amazing amities to recognize（识别）particular sounds. For example, a mother often can tell when her baby is crying even if there are other crying babies in the same room. This is because the sound of her baby’s cry has special meaning to her and the brain has recorded is importance.
The ability to recognize sounds improves with experiences. As the brain receives information about sounds from day to day, it stores the information in its memory. When the brain hears new sounds, it gives meaning to them based on the information already in the memory. This is why certain words or songs can make a person happy. Often it is not the words or songs themselves that cause this feeling. The sounds are connected to happy memories for that person.
After hearing process controlled by the brain is to decide where a sound is coming from. One ear is usually closer to the source (来源) of a sound than the other ear is. Sound waves are stronger when they reach the ear that is closer. They also reach the closer ear first. The brain recognizes these differences and uses them to decide the location of the source of the sound.
小题1:Which of the following shows the normal hearing process of a mother hearing her baby crying?
a. The ears receive the sound waves.
b. The mother recognizes her baby’s cry.
c. The ears turn the sound waves into signals.
d. The baby’s cry ravels in the form of sound waves
e. The brain connects the signals to the information in me memory.
| A．d-a-c-b-e | B．d-a-c-e-b | C．a-d-c-b-e | D．a-d-c-e-b |
| A．lifestyle | B．personality | C．experiences | D．hobbies |
| A．where the source of a sound is | B．how loud a sound is |
| C．when a sound starts to appear | D．what makes a sound |
| A．Human Brain’s Amazing Facts |
| B．Human Hearing Characteristics |
| C．How to improve Hearing |
| D．How Do Humans Hear |
Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.
The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.
This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better.

Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks (攻击) suggests that sharks don’t like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite (咬). Why is this?
There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious (好奇的). We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet., the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.
Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨头). It is hard for a shark to eat us because sharks don’t have hands, and they can’t pull the meat off our bones. Maybe that’s why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!
Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for a seal. An example of this is when a shark attack attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.
Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.
小题1:What happens to people attacked by sharks?
| A．Most of them because blind. | B．Most of them because of deaf. |
| C．Most of them died. | D．Most of them are still alive. |
| A．By biting. | B．By smelling. |
| C．By touching. | D．By killing. |
| A．Sharks pull meat off bones when they eat. |
| B．Sharks might mistake humans for seals. |
| C．Sharks like to attack surfers because of their thick fat. |
| D．One bite from a shark is nothing serious. |
| A．To tell surfers to stay away from sharks. |
| B．To ask people to stop killing sharks. |
| C．To let us know the reasons for shark attacks on people. |
| D．To show that humans are much stronger than sharks. |
