The London Olympic Games are coming soon. This summer, Chinese sports fans will be able to watch the exciting games in 3-D on CCTV.
When you watch 3-D movies or TV, you have to wear a special pair of glasses. The 3-D glasses make the people and the things on the screen look like they are in the room with you.
3-D, means having three *dimensions: *width, height and *depth. 3-D technology is based on the way the human brain and eye work. Because the *pupils of a person’s eyes are about 6.5cm apart, when we look at something, each eye sees it from different *angle. Our eyes send the two pictures to our brain, and the brain puts them together. The small difference between the picture from the right eye and the picture from the left eye make us see depth.
While watching 2-D films, we don’t have to wear the special glasses. We see the pictures in two dimensions, each eye get the same information. This is because there is only one way of watching it.
So the aim of 3-D technology is to get a different picture into each eye of the person. It uses two film *projectors. One *projects a left eye picture and the other projects a right eye picture. When we are in the cinema, we can see different pictures in each eye at the same time with the help of the 3-D glasses.
While watching 3-D films, we feel that we are actually in the same environment as the things we are watching. However, some people are against watching 3-D films. One of the reasons is the 3-D glasses makes the screen of the film or TV look darker. It is bad for eyes. What’s more, people with eye problems may get headaches if they spend too much time watching 3-D movies, because their brains need to work harder to “read” the pictures.

Car accidents happen everywhere every day and are the main cause of injury in the United States. In order to control the increasing（增長） accidents, many states have passed tough laws. Also, car manufacturers（制造商） have been trying to make safer cars to save lives.
However, as there are more and more cars and drivers on the road, these safety measure （安全措施）are not enough to stop the increasing car accidents. The National Highway Traffic Safety Administration （管理部門）reports that a car accident happens every 10 seconds in the United States.
Car accidents may be caused by different reasons. Some accidents are caused by driver’s tiredness and illness or drunk driving. Some may be caused by speeding or running a red light. When this happens, by the time the driver realizes what has happened, it is usually too late. As for ages, young drivers usually have enough experience while elderly drivers of react slowly. Mechanical defects （機械毛病）such as a broken brake（剎車） are another cause of car accidents. Poor road and weather conditions can also be a cause.
Talking about different causes of car accidents can help us know what precautions（預防措施） to take beforehand. We should tell our friends or family members not to drive in poor health or after drinking wine. We should tell teenager drivers to be careful with road and weather conditions and let elderly friends understand their driving limitation(局限性)。Besides, we should have our car checked regularly（規律地）. The most important thing for us to remember, however, is that we should always follow the traffic rules.
【小題1】What has the government done to try to control the increasing car accidents?
| A．They try to make safer cars. | B．They try to build more roads. |
| C．They have passed tough traffic laws. | D．They make drivers have their car examined every month. |
| A．Middle-aged | B．Young | C．Rather old | D．Teenage |
| A．Tiredness | B．Illness | C．Drinking | D．a broken brake |
| A．Teenager drivers. | B．Not knowing the traffic rules |
| C．Reacting slowly | D．Driving slowly. |
| A．not run a red light. | B．drive the car when we are in good health |
| C．not drive when we are too old. | D．have our cars examined regularly. |
For hundreds Of years, scientists have been trying to answer what things have an effect on people’s emotions (情感). How you feel is controlled by many things. Your emotions can be affected by your personality, by the actions of others and by events around you. Perhaps you don’t know your emotions can be influenced by the weather as well.
People often say they feel good when the sun is shining and sad when it is cloudy. In fact, sunlight makes us feel good. When sunlight hits our skins, our bodies produce a vitamin. Vitamins are natural chemicals (化學物質) which we all need to stay healthy. Sunlight helps our bodies produce vitamin D. Vitamin D helps our bodies make a special chemical. This special chemical affects our brains (大腦) and makes us feel happy. For example, there are long, dark winters of little sunlight in Sweden and Norway, so many people in these countries often feel sad. Without much sunlight, their bodies produce less vitamin D. Without enough vitamin D, their bodies make less of this special chemical which makes them feel good. To help the people in these countries feel better, special “sunrooms” with artificial (人造的) lights have been built. People can go there and get “sunlight” for an hour or two!
The weather can also affect people’s emotions in other ways. Hot weather can make people angry because people feel uncomfortable when they are hot. In the same way, rain can make people angry because being wet can be unpleasant. As you can see, the weather can have an effect on the chemicals which control our brains. Through these ways, the weather can influence our emotions. Sadly, while the weather can change us, we can hardly change the weather.
【小題1】 Which of the following is NOT mentioned as a factor (因素) that can affect one’s emotions?

| A．It is a kind of artificial chemical. |
| B．It makes us worried by affecting our brains. |

| A．We feel good when we are in the bright cool weather. |
| B．We will be happy when we are caught in the rain. |
| C．All people in Norway and Sweden feel sad in winter. |
| D．The more vitamin D you have, the happier you’ll be. |
| A．Why Do We Feel Sad? |
| B．The Weather Influences People’s Emotions |
| C．People Need More Vitamin D |
| D．We Can Hardly Change the Weather |
