Do you often feel sleepy, like something is weighing down on your head? Do you feel forgetful? Do you sometimes feel uncomfortable up and down your neck and lower back, and you can't explain why?

We have got so used to using computers that we often neglect to think of them as dangerous sources of harmful radiation. A safe amount of radiation is 25 V/m (Volts/meter). Do you want to guess how much our personal computers give off? Keyboard: 1000 V/m Mouse: 450 V/m Monitor: 218V/m CPU: 170V/m Notebook computers: 2,500 V/m Ways of Protect Yourself from Harmful Computer Radiation 1. Decorate your desk with cactus plants, they take in radiation. 2. Drink two to three cups of green tea a day and eat an orange daily. The vitamins in tea leaves and oranges protect us from radiation and keep our eyes healthy as well. 3. Use a screen filter for your monitor. 4. Avoid having metal objects nearby on your desk. 5. Put the back of the computer to the wall. Most of the radiation comes off the back. 6. Keep your monitor at least 50cm away from your face. 7. Keep your computer rooms ventilated . 8. Eat healthily-----especially fruits and vegetables. 9. Don't fall asleep on your computer. Turn it off if you have to rest nearby. The ways above are useful, why not have a try at once? Question: The best title of the passage is _ . Options: A: Computer problems B: Computer radiation: a silent killer C: Protect yourself D: Harmful radiation

Before this global sporting event, we started thinking about sports that didn't exist any more and sports that were maybe a little strange. Read the following ones that have ever been included in the past Olympic Games. Live Pigeon Shooting (1900) This bloody event was only held once, at the 1900 Paris Games. Nearly 300 birds were killed during the competition, leaving a crime scene of feathers and blood. This is the only event in Olympic history that involved killing live animals. Kabaddi (1936) This sport is popular in South Asia. The object is for one member of a team to enter the other side's half of the field, and score points. The attacker then returns to his half of the field. 12 Hour Bicycle Race (1896) Seven riders got on their bikes at 5 a.m. and rode until 5 p.m. Four riders dropped out before noon, but the winner, Adolf Schmal of Austria, managed about 180 miles. Only Schmal and one other finished. Tug of War (1900--1920) This may seem like a basic PE class sport more than an Olympic event, but Tug of War was actually one of the first sports played at the Olympic games in 500 BC. There are two teams of eight; the winning team must pull the other team six feet forward. Swimming Obstacle Race (1900) The athletes had to climb over a pole and a row of boats, and then swim under another row of boats. All of this was done in the Seine River, so they also had to fight against the water. This event was only ever held in 1900, in Paris. Question: Which sport looks like a common activity more than an Olympic event? Options: A: Swimming Obstacle Race. B: 12 Hour Bicycle Race. C: Live Pigeon Shooting. D: Tug of War.

Already in such countries as America, almost every family has a car. Many accidents happen because cars are now made to travel very fast. Also, people waste time and money every day as long lines of cars move slowly into towns and cities. In most big towns it is very hard to find parking spaces. Wide, smooth , straight roads must be built now in place of the old and narrow roads. These roads must not pass through towns and cities. They must not be crossed by other roads. Today such roads are being built in many countries in the world. These roads have at least two lanes , one for slow-moving traffic and the other for fast-moving traffic. These roads do not pass through town and cities; horses and bikes are not allowed on them. Accidents do not usually happen. Cars can travel hundreds of miles without having to stop. But these modem roads often cannot be built in towns and cities. Before a road in a town can be made wider, many buildings have to be pulled down. Some people feel that more car-parks should be built outside a city, then the drivers should leave their cars and catch a bus or take a taxi to their offices. Question: The writer thinks that many accidents happen because _ . Options: A: roads are old and narrow B: roads go across each other C: people drive their cars too fast D: all of the above
