　　Dolphins (海豚) are not fish. They are mammals (哺乳動(dòng)物). They live in groups and speak to each other in their own language. But they aren’t the same as almost all land animals. Their brains are as big as men's and they live a long life一at least 20 or 30 years.

　　Like some animals, dolphins use some sounds to help them find their ways around.They also use sounds to talk to each other and to help them find food. They don’t use their ears to receive sounds, but use the jaws (下顎).

　　It’s strange that dolphins are friendly to men, and for thousands of years, there are many stories about dolphins and men. In the 19th century, in a dangerous part of the sea near New Zealand, there was a dolphin. The seamen liked him very much and gave him a very good name, Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. In 1903, a passenger on a boat with the name of “The Penguin” shot and hurt Jack. Luckily the dolphin didn’t die, and after a long time he was well again. He guided the ships through the area for nine more years, but he refused to help the boat “The Penguin”.

　　Today, some people still kill dolphins, but more people in the world protect them.

　　Almost every Chinese person can recite the two lines of the famous poem, “Every grain on the plate comes from hard work(誰(shuí)知盤中餐，粒粒皆辛苦).” But sadly, many of us don’t actually get the real meaning of these lines: Don’t waste food.

　　A CCTV program,　News One Plus One, reported that the food Chinese people throw away every year is enough to feed 200million people for a year.

　　Do we have too much food? Of course not. According to the UN World Food Program, there were 925 million hungry people around the world in 2010, especially in developing countries. Six million children die of hunger every year.

　　Chinese people are well known for being hospitable(好客的) and generous. Many even feel that they lose face if their guests have eaten all the food on the table.

　　Luckily, a number of people have realized the importance of saving food. Last November, Li Hong, a waitress in a restaurant in Nanjing, got fired because she took some leftover food home for her son. Many people stood by her side and criticized(批評(píng)) the waste of food.

　　What should we do in our daily lives to waste less food? Here are some tips:

　　(1) Do not order too much in a restaurant. Only order as much as you want to eat. If you cannot eat all the food you ordered, take the rest of it home.

　　(2) Don’t be too picky(挑剔的) about food. Some food may not taste great, but your body needs it.

　　(3)Keep an eye on what food you have at home. Don’t buy too much, especially for vegetables and fruit.
