Europe, Germany (德国) and northern European countries work very hard to
improve the environment. The people in Germany put their rubbish into different

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?
    ___________________________________________________
3. Can we give a Muslim friend a bottle of alcohol as a gift?

  Have you ever been to the forest alone or with your friends during your holiday? If you go into the
forest with your friends, stay with them. If you don't, you may get lost. If you really get lost, this is what you
should do.
  Sit down and stay where you are. Don't try to find your friends-let them find you by staying in one
place. There is another way to help your friends or other nearby people to find you. Give them a signal

  If you don't think that you will get help before night comes, try to make a little house with branche
