　　The young boy saw me, or rather, he saw the car and quickly ran up to me ,cager to sell his bunches（串）of bananas and bags of peanuts. Though he appeared to be about twelve, he seemed to have already known he bitterness of life.“Banans 300 mira Peaouts 200 naira

”He said in a low voice. I hargained him down to 200 that for the fruit and nuts, When he agreed, I handed him a 500 nairu bill. He didn't have change. So I tole him not to worry. He said thanks and smiled a row of perfect teeth.

　　When, two weeks later, I saw the boy again, I was more aware of my position in a society where it's not that uncommon to see a little boy who should be in school standing on the corner selling fruit in the burning sun. My parents bad raised me to be aware of the advantage we had been afforded and the responsibility it brought to us.

　　I pulled over and rolled down my window, He had a bunch of bananas and a bag of peanuts ready. I waved them away.

　　“What't up?”asked him.

　　“I don't have money to buy books for school.”I reached into my pocket and abnded him two fresh 500 naira bills.“Will this help?”I asked. He looked around nervously before taking the money. One thousand naira was a lot of money to someone whose family probably made about 5,000 naira or less each year.“Thank you, sir.”he said.“Thank you very much!”

　　When driving home. I wondered if my little friend actually used the money for schoolbooks. What if he's a cheat（骗子）?And then I wondered why I did it. Did I do it to make myself feel better? Was I using him? Later, I rcalized that I wondered why I did it, Did I do it to make myself feel better? Was I using him? Later, I rcalized that I didn't know his name or the least bit about him, nor did I think to ask.

　　Over the next six months, I was busy working in a news agency in northern Nigeria Sometime after I returned ,I went out For a drive. When I was about to pull over, the boy suddenly appeared by my window with a big smile ready on his face.

　　“Oh, gosh! Long time.”

　　“Are you in school now?”I asked.

　　He nodded.

　　“That's good,” I said. A silence fell as we looked at each other, and then I realized what he wanted.“Here,”I held out a 500 naira bill.“Take this.”He shook his head and stepped back as if hurt.“What's wrong?”I asked.“It's a gift.”

　　He shook his head again and brought his had form bchind his back. His face shone with sweat（汗水）. He dropped a bunch of banans and a bag of peanuts in the front seat before he said,“I've been waiting to give hese to you .”

     Today we tell you about some new understanding of why cutting the main branch of a plant
or tree can lead to better development.
     The findings are from researchers on two_continents.Professor Prezemyslaw Prusinkiewicz
of the University of Calgary in Canada led the research with scientists from Britain and Sweden.
Their study appears in the Proceedings of the National Academy of Sciences.
     Researchers have known since the 1930s that the actively growing tip of a plant produces
a hormone(荷尔蒙)called auxin(生长素)．This hormone flows down the main stem.Scientists
say the auxin has an indirect effect on buds(芽)on the side of the stem to prevent branching.
T     hese buds themselves also produce auxin.The research suggests that to grow,they have
to be able to export the hormone into the main stem.But the flow from the stem tip prevents
them from doing this.The researchers wanted to find out how this blocking happens.
     Professor Prusinkiewicz is on leave in Australia,but he sent us an e－mail suggesting a
simple way to understand the process.Think of a major road crowded with traffic.So many
cars are on the main road that the cars on the side roads cannot enter.
     The stem is like the crowded main road.The new research shows that the buds on the
side cannot export their auxin into the main stem because it is too full.But if that main shoot
is pruned(修剪),other buds below it can start exporting.They are no longer prevented from
growing.
     Ottoline Leyser from the University of York says that after a plant is pruned,all the
inhibited(被抑制的)shoot tips compete with each other to grow.In doing this,the branches
influence each other's growth.Nearby shoot tips are more likely to affect each other than those
that are far apart from each other.
     Professor Leyser says the strongest branches grow best,wherever they may be on the
plant.The study found that the main shoot grows the best of all not because of its position at
the top of the plant,but mostly because it got there first.

C．be watered as much as possible

A．Researchers have recently found out that the growing tip of a plant produces hormones.
B．Auxin has a direct effect on buds to keep branches from growing.
C．Buds on the side of the stem can’t produce hormones.
D．In order to grow，the buds on the side of the stem export the hormones into the main stem.

5．Which of the following may be the best title for this passage?

A．Why shoot tips grow fast?
