When you do not use your arms or your legs for some time, they will become weak. When you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory (记忆 ) works in the same way.
When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
If a friend says that his arms and legs are weak, we know that it is his own fault (过错). But if he tells us that he has a poor memory, many of us think that his parents may be blamed (责备 ) , and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write but they have to remember things, they cannot write them down in a small notebook. They have to remember days, names, songs and stories, so their memory is being exercised the whole time.
So if you want to have a good memory, learn from the people: practice remembering things in a way as other people do.

Butterflies are common all over the world，but butterflies in hotter countries are usually bigger and more brightly colored than those in coo1er countries，and there are more different kinds．
Usually the male(雄性的)butterflies are more brightly colored than the females．The females have bigger and heavier bodies since they carry the eggs．The bright colors of the males help to attract the females，and the duller(较暗淡的)colors of the females make them less likely(可能的)to be caught by enemies before they have laid their eggs．
Some butterflies have bright pattern colors on the upper surface of their wings that show when flying ,but when they rest on a tree or leaves , they close their wings．On the undersides of their wings there are green and brown marks which look like the tree or leaves．They are then difficult to be seen．The best example of this is the Dead Leaf Butterfly．When its wings are c1osed，it looks exactly like a dead leaf．There are even marks that look like the holes in a dead leaf．When the butterfly is run after by a bird，it closes its wings and seems to have disappeared completely．
Many butterflies have round marks on their wings that look like eyes．The round marks have a useful function(功能)．When the butterflies are resting，their wings are closed，and these marks can’t be seen. When a bird sees one，and begins to attack it，the butterfly will open its Wings. The bird thinks that it sees two eyes staring at it，frightened，and flies away．

Most students have biology classes in the classrooms or the labs in China．But several days ago，I had a biology class outside in my American schoo1．
My biology teacher，Mr.Kwak，divided us into three groups and asked us to play a game about natural selection(选择)and how birds find food．
He gave the first group one spoon per person，the second group forks and my group"knives．I thought we were going hunting，so knives might work better．Surprisingly，he told us to pick up the beans on the grass with our tools．
When the game started all of us ran to the grass area．We squatted(蹲)down and looked for beans．It was hard to pick up something that small，especially from the grass .
When I almost fired a bean，it dropped back to the ground．When I finally picked up several beans．one of my friends ran into me．I couldn’t keep my balance and fell over．All my beans dropped to the ground!Just at that moment，Mr．Kwak called us back．I had to leave the game and of course I got a bad result．I couldn’t help thinking that if I were a bird living on Galapagos Island，I would be dead soon．
The fun game made me realize that natural selection is redly competitive(竞争的)．Everyone is trying his or her best to—survive．

There is a sign at a Korean university asking tourists not to step into the grass to take photos. The sign is not written in Korean or English; it is written in Chinese.
These signs, and signs in other countries warning Chinese tourists about their behavior, have shamed many Chinese who worry about the image of the country.
Over 70 million Chinese tourists made overseas trips last year and spent $102 billion, more than the $84 billion spent by American and German tourists. For many Chinese tourists, it was their first trip abroad and they didn’t know about foreign ways. And some of these tourists took their bad habits from China with them.
Wang Yang, a Chinese deputy prime minister(国务院副总理), said, “They(the tourists) speak loudly in public, carve words or numbers on tourist attractions, cross the road when the traffic lights are still red and spit anywhere. It damages(毁坏) the image of the Chinese people and has a very bad influence.”
Before you travel to a foreign country, it’s important to learn some things about the country and its culture. You are guests in the country and it’s important to respect(尊重) your hosts. As more and more Chinese visit foreign countries, their behavior will certainly change and those shameful signs will, hopefully, disappear.
The sign at a Korean university is written in ______.
A. Chinese B. English C. Korean
How do many Chinese feel about the signs?
A. Proud.
B. Interested.
C. Shameful.
The underlined word “image” probably means “______” in Chinese.
A. 形象 B. 热情 C. 财富
The passage is written to ______.
A. order the Korean university to clean up signs with Chinese words
B. advise the overseas Chinese tourists to change their behavior
C. ask Chinese people not to spend too much money traveling abroad
What would be the best title for the passage?
A. Signs Shame Overseas Chinese Tourists
B. Foreign Culture Makes Bad Influence
C. Foreign Countries Attract Chinese Tourists
