题目列表(包括答案和解析)

Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.

  Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.

If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.

Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.

阅读文章,回答下列问题。
  Gift giving is different from culture to culture and person to person.
  When giving gifts, sometimes color is important. For example, for many
Chinese people around the world, red is a lucky color, and people often like to
wrap gifts in this color.
  However, did you know that in Korea, red is a color of death? That is why
you should not wrap your gifts in this color if you are giving a gift to a Korean
person.What about western countries? In western countries, the color of
wrapping paper is not really important. But color does matter when giving
flowers, especially roses. You should not give red roses to a western person you
don't know very well because they are a symbol of love.
  You could give yellow roses instead as these are a symbol of friendship.
You could also send pink roses as gifts to say thank you.
  What other things should you remember when giving gifts to someone from a
different culture? Well, one thing you should keep in mind is the person's religion
(宗教). When choosing a gift for a Muslim (穆斯林) or Jewish (犹太教的)
friend, you should never get food including pork, or things made from pigskin.
Another thing that you should not get for a Muslim person is alcohol (酒). 
1. In which country do people think red is the color of death?

2. How can we show our friendship to the western friends?
    ___________________________________________________
