Trees are one of the oldest citizens（公民）of our earth．Just like US，trees change a lot when they grow．At one to three years old，young trees learn how to protect themselves．For example，many trees grow thorns（刺）to tell animals not to go near．Most young trees have large，deep green leaves so that they can catch enough sunlight and change it into their food and energy．
When trees are 4 years old，they begin to grow very fast and become strong enough to face challenges（挑战）in life．
At the age of l5，trees become young adults．They grow more slowly and begin to produce flowers and fruit．
It is not until the trees are 20 to 25 years old that they become real adults．The trees reach their largest sizes．Adult trees give US many things such as oxygen（氧气）and natural beauty．If we give them good care，they will go on to live healthily for many years．
As time goes on，trees begin to grow older and older and even die．At this time，they still have their important place in nature．In many ways，the life of trees is like our own life experience. Enjoy every minute of the life of the trees and take care of them!

Giving directions in different places
If you ask people of different countries“Could you tell me the way to the post office?”。You will get different answers．
In Japan，people use landmarks（路标）instead of street names．For example，the Japanese will say to travelers，“Go straight down to the comer．1．The post office is across from the bus stop．”
In Kansas，America，there are no towns or buildings within（在……之内）miles．So instead of landmarks，people will tell you directions and distance．For example，people will say，“Go north two miles（英里）．2．
People in Greece sometimes do not even try to give directions．They will often say，“Follow me．”3． Sometimes if a person doesn’t know the answer to your question，he or she，like a New Yorker，might say，“Sorry，I have no idea．”But in Yucatan，Mexico，no one answers“I don’t know．”4．They usually give an answer，but often a wrong one．A visitor can often get lost in Yucatan!
5．You might not understand a person’s words，but maybe you can understand his or her body language．He or she will usually point to the correct direction．Go on in that direction and you may find the post office!
| Turn east，and then go another mile． But one thing will help you everywhere． People there think“I don’t know．”is not polite． Turn left at the big hotel and go past a fruit market． Then he or she will take you through the streets of the city to the post office． |
