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

　　The days of multi-layer air tickets appear numbered, as the China Air Transport Association (CATA) has stopped providing paper tickets and instructed sellers to issue e-tickets. The decision is in line with an International Air Transport Association (IATA) move that requires its 261 member airlines to abandon paper tickets by the end of 2007. E-tickets will be issued once the current batch of paper tickets has been used up. The change currently only applies to domestic flights. “We haven't received notice from the CATA that paper tickets for international flights will be stopped, ”said a ticket agent in Beijing.

　　Customers will book tickets through airlines or ticket agents as usual, and will be given a booking reference. They will then be able to use automatic check-in facilities at airports, and receive an invoice (发票) for reimbursement (报销凭证). They can also check in as normal at the counter. Special passengers like infants and those flying to airports without automatic check-in machines can still use paper tickets.

　　The wide use of e-ticketing is expected to lower operational costs, which could lead to lower prices of air tickets, said an expert with the Safety Technology Centre of the General Administration of Civil Aviation. A survey conducted by the civil aviation website, www.CARNOC.com, between August 28 and October 15 showed widespread concern over the new system. Although they had the ability to take part in the online survey,43 percent of the people who answered questions in the survey said they would prefer to receive a paper ticket. While some feel more secure without the worry of a ticket, others said they did not trust sending personal details over the Internet, or worried they would not get reimbursed.

C．How to Book Air E-tickets

D．China to Issue Air E-tickets

The hospital burn unit is a popular place on the day after Thanksgiving. I found that out three years ago, when my 18-month-old daughter touched a radiator pipe while playing around our friends' farmhouse. Instead of feasting on leftover stuffing, I rushed my child as she screamed to hospital. Instead of getting a jump on my Christmas shopping, I learned how to take care of second-degree burns.

Our story had a happy ending. With weeks of twice-daily treatments at Mommy and Papa's kitchen-table burn clinic, my daughter's hands healed. But other children we saw at the outpatient burn clinic weren't so lucky. I saw hands _____________________, a mouth that would never smile straight, a scalp that would never grow hair. All the parents had stories of accidents as easy as ours: a cup of tea knocked from a side table, a tumble（摔倒）into a space heater. "Heaters and soup," one veteran nurse told me at the hospital. "That's all it is. Heaters and soup. " 

Most of the injuries were to hands and wrists, and most came from contact with hot liquids or from touching hot objects. Not only do small children not realize the danger posed by hot objects; their skin is much thinner than that of adults. They burn more quickly, and the burns tend to be deeper and more severe.

Traditional fire safety education focused on preventing fires. The number of children injured by playing with fire has declined substantially when the Consumer Product Safety Commission required that cigarette lighters be child-resistant. "We know people know about smoke alarms," says Chrissy, program manager for Safe Kids USA, a nonprofit that works to reduce childhood injuries. Now, fire safety experts hope that public education efforts will turn to burns that can be just as terrible as injuries caused by flame.
