Not long ago, I answered a telephone call from an old friend who I’d not heard from for a long time. “Hi, my goodfriend,” said the voice on the end. “I just wanted to see howyou’re getting long.”At the end of the conversation, he said, “if you need me in any way, I’ll be happy to help out.” And he meant it! That call came at just the right time. I needed those words of encouragement (鼓励). I hung up the phone and felt very warm in my heart.And that day I relearned something important about life: Life is first about people, not to-do lists and a million tasks left undone—it’s about people.To love and to know that we are loved is the greatest happiness. And happiness seems to be something that too many of us are short of (缺少)! My friend reminded (提醒) me that it is never enough just to love; we must also express (表达) it.George William Childs put it like this: “Do not keep the box of your love and friendship closed up until your friends are gone.

They have almost as much protein (蛋白质) as meat from a pig or cow and are low in fat. Eating insects is also very good for the environment (环境) since they need less land and water than larger animals.Marcel Dicke, who studies insects, explained (解释) in a talk how insects also produce more meat from the food they eat. For example, imagine a farmer feeds a cow 10 pounds of food. Those 10 pounds of food produce about 1 pound of meat for people to eat. However, imagine the farmer gives a certain number of insects 10 pounds of food. Those 10 pounds of food produce 9 pounds of meat for people to eat!Eating more insects can also help people in poor areas. Many people can raise (饲养) and sell insects, which can provide jobs and food.But insects will not replace (替代) animal meat very quickly. First, people in some countries would have to change how they think about eating insects. Many people in North America and Europe eat a lot of meat like beef and pork. But they don’t traditionally eat insects. In fact, for many people in the west, eating insects sounds crazy! They believe insects are dirty and dangerous. Insects make them feel uncomfortable.Some people are trying to deal with this problem. For example, David George Gordon wrote a book named The Eat-A-Bug Cookbook, which tries to show people that insects can be delicious. Other insect experts (专家) travel around telling people about the benefit (好处) of eating insects. But they still have a lot of work to do.【小题1】What can we get if we eat the insects?A．Protein. B．Fat. C．Water. D．Carbon dioxide.【小题2】Eating insects ________.A．is not healthy B．makes people put on fat C．helps protect large animals D．is environmentally friendly 【小题3】The examples of Marcel Dicke is given to show _________. A．the high cost of food productionB．it’s quite easy for farmers to raise insectsC．raising insects need less food than larger animalsD．the different ways of feeding cows and insects【小题4】What mainly causes the long way that eating insects has to go?A．Their terrible taste. B．People’s old belief.C．Family life. D．Eating ways.【小题5】We can infer (推断) from David and other insects expertsthat ______.A．people can make a lot of money from insectsB．insects should be better protectedC．people should eat more insectsD．it’s dangerous to eat insects五、根据首字母填空20.
