Throughout history, rainbows have been a source of mystery and legend. Rainbows are also important symbols in a number of cultures around the world. In the Old Testament of the Bible(<<>> ), for example, God shows Noah a rainbow to let him know that the Flood is over and that he will never destroy the earth again with flooding.  When it rains, the color1s that make up white light separate because they bend at different angles when they pass through water. The result is some of the color1s can be seen by the human eyes, as well as some that cannot. Everyone knows that we can sometimes see rainbows on a rainy day. However, you actually have a chance of seeing a rainbow anytime there is light behind you and water in the air in front of you. So, if you want to know what it feels like to have the power of God, get a spray , stand with your back to the sun, and create a rainbow! In the Old Testament of the Bible, the rainbow is used to   _  . A) deliver a message B) tell a story C) give an order D) stand for God

People in cities all over the world shop in supermarkets. Who decides what you buy in the supermarket? Do you decide? Does the supermarket decide? When you enter the supermarket, you see shelves full of food. You walk in the aisles   between the shelves. You push a shopping cart and put your food in it. You probably hear soft, slow music as you walk along the aisles. This may be an attempt to please you, so you will enjoy shopping. Some supermarkets want to increase their profits by playing soft and slow music, because the slow music makes you walk slowly and you have more time to buy things. Fresh fruit and vegetables are usually put near the entrance. When you arrive at the supermarket, you think about the kinds of fruit and vegetables you need first. Once you've got that out of the way, you can relax and do the rest of the shopping without any hurry. Besides, if you see fresh goods first, it gives you a "feel good" impression of freshness, so you can not help spending your money. Maybe you go to the meat department then. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk past all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale. Most of the food in supermarkets is very attractive. It all says "Buy me quickly!" to the customers. The fresh fruit and vegetables say "Buy me quickly!" as you walk by. The expensive meat says "Buy me quickly!" The supermarket tells you what to buy. Some supermarkets play soft, slow music because it    _   . A) makes customers walk slowly and buy more B) can help customers get the things they want C) can make customers relaxed and happy D) can tell customers exactly where to go

"I'd like to be at a healthier weight," a friend told me. "But we just don't have the money to buy expensive diet foods and there isn't enough money to join a gym." Many people feel that way -- that a healthy diet and exercise plan is out of reach because of their high cost. Don't lose hope! We'll be looking at ways to make healthy choices without spending too much money.  First you don't need to buy the expensive pre-prepared "diet foods." Back in the early 1970s when I started housekeeping, 90% of the food I bought was ingredients. Very few things were preprocessed  . Now 90% of the food you find in the store is quick food. That's a bad thing.  Quick foods like boxed "just add hamburger" meals have had the fiber   removed to make them faster to prepare. Take a look at the label   on that box. It often has low numbers listed under "fiber" because fiber takes longer to digest. If the low fiber meal is digested, the result is that your body begins to store fat. Besides, your body is short of nutrients  . You will be driven to eat more to try to make up for the low quality of the food you are eating. And then there are the chemicals the producers add to the quick meals to make them palatable. If not, the stuff would taste like cardboard and you wouldn't enjoy it. However, these chemicals certainly aren't good for your health.  What's the answer? Buy whole ingredients and give up the expensive, low nutrition, processed foods. Do the cooking yourself and you will have control over what is in your food -- and it will cost less, too. People who find it hard to get a healthier weight think   _  . A) they had too much diet food B) they didn't make a detailed plan C) they have no time to do exercise in gym D) they can't afford diet food and to exercise in gym

BEIJING, June. 30(Xinhua)----There are ten times as many Chinese newspapers and magazines than there were 30 years ago. That's when the country adopted the reform and opening-up policy.

Rapid economic development and universal education since China adopted the reform has helped fuel the need for more information sources.        Under the market economy, hundreds of publishing houses and newspapers have taken steps to restructure management systems into corporations listed on the stock market.

Its industrial volume amounted to 20 billion yuan (2.93 billion U.S. dollars) in 2006.
