In China, a lot of food is wasted every year and the waste food is enough for     people. The food is wasted in restaurants, at home and in schools, etc.

In restaurants or at home, people often order or cook         food. But they can’t eat it up。When they go out of a restaurant, full and happy, they never look back         the uncertain food on the table again. Should Chinese consumers (消费者) feel          for the terrible waste?

In schools, we can often see a lot of students        food away after meals and they only eat the food they like.

Everyone is supposed to have enough food to eat. However, in some places, the food is so little        a lot of people died from hunger. Although China has tried hard to solve       of hunger over the past thirty years, the job is not finished yet. Food is important to us all. We     live without food. So          is necessary for us to love food and try to eat up everything on our plates. When we eat in restaurants, we should pack up the leftovers(剩菜剩饭). We also need to tell other people to stop           food as soon as possible.

In nature, you may see many insects (昆虫）and animals of different colors. Have you ever wondered why?

   Locusts are super delicious food for birds,but it is not always an easy job for birds to catch them.It is neither because locusts are good jumpers or runners nor because they are smarter than their enemies. The reason is that the colors of locusts change with the colors of crops(庄稼). When crops are young,locusts look green. But when autumn comes, locusts change to the yellow and brown color as crops do.

   Brown bears,tigers and other animals move quietly through forests. They can’t be seen easily by their enemies. This is because they have colors similar to the trees. For the same reason, polar bears that live on a land of snow and ice are white. Butterflies and bees living among the flowers are colorful like flowers. Soil insects are mostly dark-colored and they live under the soil(土壤） in a dark and wet environment. However, insects with colors different from plants can easily be found and eaten by others. So in order to survive,they have to hide themselves in the daytime and appear only at night.

   Have you ever noticed some even stranger acts? The ink fish in the sea can send out some very black ink when it faces danger. As the ink spreads over , its enemies will find themselves suddenly in a dark world. At the same time the ink fish immediately swims away. That is how it keeps itself safe though it is not strong at all.

In 1912 Gaffet A．Morga was worried about the large number of fires in the factory of his city．He wanted to make something that would protect the people who had to fight the fire. They were often hurt．Sometimes they were killed by gas and smoke．They needed something that would help them put out fires quickly and safely．

    Morgan developed the safety hood（头罩）. It was a hood to be worn over the face. Two tubes ran down the back leading to an air trap（空气收集器）of clean air below．This hood allowed the firefighters to remain in smoke-filled rooms longer and with less danger.

On July 25．Cleveland，Ohio was rocked（震撼）by an explosion（爆炸）．The explosion trapped（困住）thirty-two workers in a tunnel（隧道）under Lake Erie. Morgan was called to help．Morgan and his brother，Frank，and two other men put on safety hoods. They went into the tunnel．They brought out all the workers．who were still alive．For his help，Morgan received medals（奖牌）from the city of Cleveland and the International Association of Fire Engineers．

    Morgan improved this safety hood in 1917 T11e11 in 1923，he made something else to help make the world safer for people．Morgan invented the first electric traffic signal.
