When you cut your skin, you bleed(流血). If a person loses a lot of blood, he will become ill and may die. Blood is very important. People have always known that. At one time, some people even drank blood to make them strong!

When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called " blood transfusion（输血）". The blood goes from the arm of the healthy person into the arm of the sick person.

But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four groups—O, A, B and AB. We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB. But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely.

There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time.

We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may become ill. You may need blood. The "blood bank" will give it to you.

When I was growing up, I had an old neighbor, Dr. Gibbs. He didn’t look like any doctor I’d ever known. He never invited us to play in his yard, but he was a very kind person.
When Dr. Gibbs wasn’t saving lives, he was planting trees. He owned a large field and wanted to make it a forest.
The good doctor had some interesting ideas about planting trees. He never watered his new trees. Once I asked why. He said that watering plants spoiled them, and that if you watered them, each baby tree would grow weaker and weaker, so you had to make things difficult for them and pick out the weaker trees early on.
He talked about how watering trees made for shallow（浅的）roots, and how trees that weren’t watered had to grow deep roots in search of water under the earth by themselves. Deep roots were very important.
So he never watered his trees. He’d planted an oak and, instead of watering it every morning, he’d beat it with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree’s attention.
Dr. Gibbs died several years after I left home. Every now and then, I walked by his house and looked at the trees that I watched him plant about twenty-five years ago. They’re very big and strong now. I planted some trees a few years back and carried water to them for whole summer.
After two years of caring too much, whenever a cold wind blows in, they shake a lot.
Every night before I go to bed, I check on my two sons. Mostly I pray（祈祷）that their lives will be easy. But lately I’ve been thinking that it’s time to change my prayer. I know my children are going to face difficulties. There’s always cold wind blowing somewhere, so what we need to do is to pray for roots that reach deep into the brave heart, so when the rains fall and the winds blow, we could face it strongly and won’t be beaten down.
【小题1】We know from the passage the doctor           .

When I was growing up, I had an old neighbor, Dr. Gibbs. He didn't look like any doctor I'd ever known. He never invited us to play in his yard, but he was a very kind person. When Dr. Gibbs wasn't saving lives, he was planting trees. He owned a large field and wanted to make it a forest. The good doctor had some interesting ideas about planting trees. He never watered his new trees. Once I asked why. He said that watering plants spoiled(毁坏) them, and that if you watered them, each baby tree would grow weaker and weaker, so you had to make things difficult for them and pick out the weaker trees early on.

He talked about how watering trees made for shallow(浅的) roots(根), and how trees that weren't watered had to grow deep roots in search of water under the earth by themselves. Deep roots were very important. So he never watered his trees. He'd planted an oak(橡树)and instead of watering it every morning, he'd beat it with a rolled-up newspaper. I asked him why he did that, and he said it was to get the tree's attention.

Dr. Gibbs died several years after I left home. Every now and then, I walked by his house and looked at the trees that I watched him plant about twenty-five years ago. They're very big and strong now. I planted some trees a few years back and carried water to them for a whole summer. After two years of caring too much, whenever a cold wind blows in, they shake a lot.

Every night before I go to bed, I check on my two sons. Mostly I pray (祈祷) that their lives will be easy. But lately I've been thinking that it's time to change my prayer. I know my children are going to face difficulties. There's always a cold wind blowing somewhere, so what we need to do is to pray for roots that reach deep into the brave heart, so when the rains fall and the winds blow, we could face it strongly and won't be beaten down.
