1 . Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.

Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil—make the rain in—and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.

6 .
Remembering names is an important social skill.Here are some ways to master it.
Recite and repeat in conversation．
When you hear a person’s name，repeat it.Immediately say it to yourself several times without moving your lips.You could also repeat the name in a way that does not sound forced or artificial.
Ask the other person to recite and repeat.
   You can let other people help you remember their names.After you’ve been introduced to someone，ask that person to spell the name and pronounce it correctly for you．Most people will be pleased by the effort you’re making to learn their names.
Admit you don’t know.
   Admitting that you can’t remember someone’s name can actually make people relaxed.Most of them will feel sympathy if you say.“I’m working to remember names better.Yours is right on the tip of my tongue.What is it again?”
Use associations．
   Link each person yon meet with one thing you find interesting or unusual.For example, you could make a mental note: “Vicki Cheng - tall, black hair.” To reinforce (加强) your associations, write them on a small card as soon as possible.
Limit the number of new names you learn at one time.
   When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.
Go early.
   Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. That’s fewer names for you to remember. And as more people arrive, you can hear them being introduced to others -an automatic review for you.

7 . It was Thanksgiving morning and in the crowded kitchen of my small home I was busy preparing the traditional Thanksgiving turkey when the doorbell rang. I opened the front door and saw two small children in rags huddling together. “Any old papers, lady?” asked one of them.
I was busy. I wanted to say “no” until I looked down at their feet. They were wearing thin little sandals, wet with heavy snow.
“Come in and I’ll make you a cup of hot cocoa.”
They walked over and sat down at the table. Their wet sandals left marks upon the floor. I served them cocoa and bread with jam to fight against the cold outside. Then I went back to the kitchen and started again on my household budget.
The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice, “Lady, are you rich?”
I looked at my shabby slipcovers. The girl put her cup back in its saucer carefully and said, “Your cups match your saucers.” Her voice was hungry with a need that no amount of food could supply. They left after that, holding their bundles of papers against the wind. They hadn’t said “Thank you.” They didn’t need to. They had reminded me that I had so much for which to be grateful. Plain blue china cups and saucers were only worth five pence. But they matched.
I tasted the potatoes and stirred the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a good steady job—these matched, too.
I moved the chairs back from the fire and cleaned the living room. The muddy prints of small sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to forget how rich I am.

8 . When an ant dies, other ants move the dead insect out. Sometimes, the dead ant get moved away very soon—within an hour of dying. This behavior is interesting to scientists, who wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist. Choe found that Argentine ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead—take me away.”
But there’s a twist to Choe’s discovery. Choe says that the living ants—not just the dead ones —have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, it’s telling other ants that it’s dead.
What keeps ants from dragging away the living ants? Choe found that Argentine ants have two additional chemicals on their bodies, and these tell nearby ants something like, “Wait—I’m not dead yet.” So Choe’s research turned up two sets of chemical             signals in ants: one says, “I’m dead,” and the other set says, “I’m not dead yet.”
Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious, for example, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive.
Choe suspects that when an Argentine ant dies, the chemical that says “Wait- I’m not dead yet” quickly goes away. Once that chemical is gone, only the one that says “I’m dead” is left. “It’s because the dead ant no longer smells like a living ant             that it gets carried to the graveyard, not because its body releases new unique chemicals after death,” said Choe. When other ants detect the “dead” chemical without the “not dead yet” chemical, they drag away the body.
Understanding this behavior may help scientists figure out how to stop Argentine ants from invading new places and causing problems. Choe would like to find a way to use the newly discovered chemicals to spread ant killer to Argentine ant nests.
The ants’ removal behavior is important to the overall health of the nest. “Being able to quickly remove dead individuals and other possible sources of disease is extremely important to all animals living in societies, including us,” says Choe. “Think             about all the effort and money that we invest daily in waste management.”
