Now more and more women are taking the front seat. More than twenty million people in the United States ride motorcycles. Since 1998 the number of female bikers has risen sharply. Lady Sport Riders began in 1999 in Washington. The women formed the organization to share their love of motorcycle riding. But later it wanted to be more than just an organization for women to gather and ride motorcycles, so it started to organize events that help national health organizations and womens shelters. It also permits women to share a strong sisterhood, and gives financial awards to poor students. Like other motorcycle clubs, the members of Lady Sport Riders also help their community. Different from male riders, female riders ride for more than fun. This sport gives women a sense of freedom and control. Female riders have helped change motorcycle culture. More than five years ago manufacturers began making equipment especially for women. Some bikes now have smaller, softer seats and controls that are easier to reach. Modern clothes for riding now look good and still provide protection. In the past, women rode motorcycles that traveled at a moderate speed. Now theirs are as powerful as the ones men ride.

But, as we cant drink seawater, how can it be important? Every part of our seas and oceans contains an amazing number of animals and fish that live at different ocean depths. Most of the different species of animals and fish depend on simple plants for their food. These simple plants called algae (海藻) drift near the surface of the ocean and use sunlight to turn carbon dioxide and water into food and oxygen. In fact, algae produce over half of the oxygen people breathe. How important seawater is! Each plant or animal in our seas and oceans is an important link in a food chain. The algae are eaten in large amounts by microscopic animals, which are in turn consumed by larger animals. These food chains are delicately balanced. The bad news about the food chains in the oceans is that they are under threat because of man. People once thought that the oceans were so big that it didnt matter if we dumped rubbish into them or caught huge quantities of fish and whales for food. But we now know this is not true and fish stocks in the oceans have started to drop. Thankfully, the world is taking steps to protect the future of our oceans by introducing international agreements to protect marine habitats. Most countries have introduced fishing restrictions to protect fish stocks in the oceans and new techniques are being pioneered to cope with pollution. Finally, the importance of protecting oceans is being made known to more people. This is just the beginning of a long process to protect the oceans for our future. We depend on the oceans for fish which are an important part of the human diet. How important seawater is! 61. Which of the following is the proper order of the food chain?

As a result, vitamin supplements（补品），though expensive, are popular with people who worry that they are not getting enough vitamins from the foods they eat. But contrary to what many people think, medical experts have found little evidence that most supplements do anything to improve health or protect against disease. In fact, medical experts warn that taking too many of some vitamins can be harmful. For example, too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors, as some vitamins can produce harmful side effects when mixed with medicines.Experts, however, do say that sometimes vitamins can help prevent disease. People who know they lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this vitamin from sunlight.Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables and other foods, like fruits. Vitamin K can be found in pork products.In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies need. 71. What is probably talked about before this passage? A. How many vitamins a persons body needs. B. How many vitamins some foods contain. C. The benefits that vitamins bring to our health. D. What people should do to stay healthy. 72. Vitamin supplements are popular with people because _. A. people mistakenly think that they are good for their healthB. they contain more vitamins than the foods people eatC. food does not provide enough vitamins people needD. people fear that a lack of vitamins will lead to disease73. From the passage, we can learn that medical experts advise people _. A. never to take any vitamin supplements B. to depend only on food for their vitamins C. not to take any vitamins together with medicinesD. to consult doctors before taking vitamin supplements74. For people who lack Vitamin B-twelve, they can eat more from _. A. sweet potatoes B. pork products C. green leafy vegetables D. eggs75. What would be the best title of the passage? A. Getting enough vitamins through a balanced diet.B. Vitamin supplements do harm to our health.C. Vitamins are important to our health.D.
