The 31st Summer Olympics will be held in Brazil in 2016. 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. What do you probably think of these events? A) Strange. B) Fantastic. C) Modern. D) Interesting.

One of the easiest and cheapest ways to help your health is just to sleep eight hours or more every night, but more and more people in the world are not sleeping enough. According to the World Health Organization, over half the people in the world may be _ . The result of this is not just a lot of tired people; in the United States alone, sleepy drivers cause at least 100,000 car accidents, and 1,500 deaths a year. Problems with sleep can also cause mental   problems, as well as medical problems such as high blood pressure and heart problems. American culture values work and often doesn't value sleep. In fact, people who sleep a lot are often called "lazy". Many famous men say proudly, "I only have time to sleep four or five hours a night." Students, especially college students, often sleep only a few hours a night. They often say, "I'm used to sleeping only a little." But according to experts, sleep is like money. If you sleep only five hours a day, you don't "get used to it", but instead, build up a "sleep deficit  ". "It's like a credit card (a card used to buy things or services)," says Dr. James Maas, "You are only borrowing time. You always have to pay it back." The more hours you don't sleep, the more hours you should sleep to "pay back" the hours on your "sleep credit card". For example, if you sleep four hours on Monday and then sleep eight hours on Tuesday, on Wednesday you will still have a "sleep deficit" of four hours. This deficit can continue for months or even years. People with a "sleep deficit" are sleep-deprived. Driving and making decisions can be dangerous for these people. Another research shows people should sleep nine or ten hours every night. More than half the people in the world may be running a "sleep deficit". You didn't do your homework last night? Maybe you can tell your teacher that you were working hard on your sleep deficit. "Don't think you will be doing less work because you sleep during the day. That's a foolish idea which is held by people who have no imagination. You... What Winston Churchill said means   _  . A) sleep more during the day, work more at night B) sleep during the day influences your work C) people who sleep during the day have no imagination D) sleep during the day is helpful to your work

There are many colours in nature. But do you know that a colour has weight? I think you'll say "no". But I am afraid you are wrong. If you don't believe, you may do a small experiment . First, put two objects with the same weight into two boxes. Then cover the boxes. Wrap  one box with a red piece of paper, the other with a white piece of paper. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier. Why does it happen? A scientist found that different colours have different weight in a man's mind. So he did many tests and at last he got the result. That is to say, every colour has its own weight in our mind. The heaviest colour is red, then blue, green, orange, yellow and white. The scientists told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientists say so? That is because every colour represents a kind of light wave ------ a certain wavelength . It reaches our brain  through organs  According to this discovery, scientists say that people accept the colour they like, and _ the colour they hate. So your body and mind will be healthy by using the colours you like. Or you'll be nervous or even get ill. If you stay in a room with red windows, wallpapers and furniture  for two hours, you'll feel you have been there for four hours. But if the room is blue, you'll feel you have been there for only one hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change when we see different colours. According to the passage, how long will you feel if you stay in a red room for an hour? A) Two hours. B) Fours hours C) Six hours D) Eight hours.
