About 97% of the world’s water is salty and is found in our oceans and seas. But, as we can’t drink sea water, 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 sea water 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 didn’t 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 sea water is!

There is an English saying, “Laughter is the best medicine.” Until recently, few people took the saying seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programmes. The group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny programme. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

44. According to the author, we should __________ in our life.

China Earthquake Leaves 5,000 Homeless
Beijing- An earthquake measuring 6.8 on the Richter scale left 50,000 people homeless, killed at least one person and injured 39 others in southwest China on Thurday, with more accidents expected.
By late Thurday, 4,900 people were declared homeless after the quake destroyed their homes in a mountainous area lying on the border between Yunnan and Sichuan provinces. The dawn quake left one dead and 39 injured, destroyed 268 houses and damaging 1,132 other buildings so seriously that they were considered uninhabitable.
Another 2,400 houses suffered less serious damage. The epicenter( 震中 ) was near scenic Lugu Lake, a tourist site, where the local school was severely damaged. Preliminary (最初的) estimates put economic losses at 180 million yuan ( 22 million dollars ).
Governments in Yanyuan and the neighbouring Yunnan county of Ninglang has joined forces in the rescue effects and tents, clothes and medicine are badly in need of for the earthquake victims.
The mountainous terrain, heavy rain and several aftershocks all prevented rescue effects on Thursday. The rain could cause more badly damaged homes to fall down.
More dead and injured are expected “as rescuers have yet to reach many faraway areas”.It is very hard for rescue workers because most houses are scattered around the mountains, which are inhabited by Yi and other ethnic minority groups (少数民族)

When did you see a polar bear ? On a trip to a zoo, perhaps ? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These “Polar Bears” are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3 degrees. And the water temperature was a little higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group; this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February.
Doctors don’t agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body’s temperature drops so slow that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and the water tempreature is much greater in summer than in winter.
The Polar Bears themselves are satisfied with the benefits of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system (循环系统) because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and could not try cold-water swimming.
The main benefits of cold-water swimming are probably mental. The Polar Bears love to swim all the year round; they find it fun and relaxing. As one 70-year-old woman says, “When I go into the water, I pour my troubles into the ocean and let them float away.”

Live Earth Announces 2010 Global Event!
This is the web version of the October 15, 2009 Live Earth email to members. Click here to join and receive bi-weekly updates from Live Earth.
Live Earth is pleased to announce the largest worldwide water initiative(倡议)in history to help fight the global water crisis. The Dow Live Earth Run for Water—to take place on April 18, 2010—will consist of a series of 6 km run/walks (the average distance many women and children walk every day to get water) taking place over the course of 24 hours in countries around the world, featuring concerts and water education activities, raising awareness and funds to help solve the water crisis. Jessica Biel, Alexandra Cousteau, Pete Wentz, Angelique Kidjo and Jenny Fletcher will lend their names and their time in support of this global event.
Water shortage is a major issue affecting countries, communities and families all over the world. One in eight people doesn’t have access to safe, clean drinking water. Communities in Africa, Latin America and Asia suffer 1.8 million deaths every year from diarrheal(腹泻）diseases and the death of 5,000 children each day due to inadequate water infrastructure(基础设施). In these areas, women and children are forced to walk 6 km (3.7 miles) each day to get water that is likely unsuitable for drinking. However, the water crisis is not only limited to developing nations. Adding to these existing issues, the effects of climate change are increasingly impacting both supply and quality of available fresh water throughout the world.
In 60% of European cities with populations greater than 100,000, groundwater is being used faster than it can be replenished(补充). By 2025, two-thirds of the world’s population could be living under water-stressed conditions.
You can help solve the water crisis by participating in the April 18th event. Run/walk registration is now officially open! Sign up now at http://liveearth.org/run.
