When Dr．Robert Metcalf first used a solar cooker，the future changed for millions of Africans．He knew that billions of poor people around the world depend on the use of wood for cooking．As they take more and more firewood from wild areas．they are destroying habitats around the world．Wood collection is one reason why many animals have become endangered．

“But sunshine can be an alternative to fire．”Dr．Metcalf says．Since his first solar cooked meal，he has helped people around the world to use simple new technologies to cook their food．

Each morning in villages across East Africa，small children and their mothers wake up and walk several miles to collect firewood to cook their food．It takes much of the day，and the heavy firewood they carry home on their heads lasts only a few days．

This is why Dr．Metcalf spends each summer in Africa．He teaches women and children in villages how to cook with the sun．So far，more than thirty thousand African families now have solar cookers，and new programs will introduce solar cookers to millions of families．

To find water，women and children may have to walk long distance to dig holes in dry riverbeds or to gather water from streams and shallow wells．

They fill their buckets（桶）and carry them home on their heads．The buckets often weigh as

much as forty pounds．Not only is finding water hard work，but the water is often polluted with

germs（细菌）that make people sick．

Dr．Metcalf and others developed a simple，reusable tool that people can use to make sure their water is safe∞drink．The tool is calked a WAPI，which stands for“Water Pasteurization Indicator”．The pasteurization process is named after Louis Pasteur，who developed it in the 1800s．

When I was young, I had an old neighbor named Dr. Gibbs. He didn’t look like any doctor I’d ever known. He never shouted at us for playing in his yard. I remembered him as a neighbor who was nicer than anyone else in the neighborhood.
When Dr. Gibbs was happy, he was planting trees. And his life’s goal was to make it a forest.
Dr. Gibbs had some interesting theories about planting. He talked about trees that weren’t watered would grow deep roots in search of water. So he never watered his trees. He planted an oak (橡树) and, instead of watering it every morning, he beat it with the rolled-up newspaper. I asked him why he did that, and he said it was to get the tree’s attention.
Dr. Gibbs died a couple of years. Every now and again, I walk by his house and look at the trees that he planted twenty-five years ago. They’re very strong now.
I planted a couple of trees a few years later. I watered them regularly and took good care of them. Whenever a cold wind blows, they shake their leaves and branches.
The funny thing about those trees of Dr. Gibbs was that difficulty seemed to help them in ways comfort and ease never could.
【小题1】What was Dr. Gibbs’ life goal?

When I was growing up, I had an old neighbor named Dr. Gibbs. He didn’t look like any doctor I’d ever known. He never yelled at us for playing in his yard. I remember him as someone who was a lot nicer than most of the adults in our community.

　　When Dr. Gibbs wasn’t saving lives, he was planting trees. His house sat on ten acres, and his life’s goal was to make it a forest.

He talked about how watering trees made for shallow roots, and how trees that weren’t watered had to grow deep roots in search of moisture. I took him to mean that deep roots were to be treasured.

　　So he never watered his trees. He planted an oak and, instead of watering it every morning, he’d beat it with a rolled-up newspaper. Smack! Slap! Pow! I asked him why he did that, and he said it was to get the tree’s attention.

Dr. Gibbs passed away a couple of years after I left home. Every now and again, I walked by his house and looked at the trees that I’d watched him plant some twenty-five years ago. They’re extremely tall, big and robust since they have deep roots now. However, the trees in my garden trembled in a cold wind although I had watered them for several years.

It seems that adversity(逆境) and suffering benefit these trees in ways comfort and ease never could. I stood there deep in thought.

　　Every night before I go to bed, I check on my two sons. I stand over them and watch their little bodies, the rising and falling of life within. I often pray for them. Mostly I pray that their lives will be easy. But I think it’s time to change my prayer(祷词) because now I know my children are going to encounter hardship..

1.According to Dr. Gibbs’ theories, trees will become weaker if they______

A. “seeing is believing” B.“Put everything in proper use”

C. ”Practice makes perfect” D. “No pains, no gains”

3..The underlined word robust in Para.5 most probably means______

A. strong B. strange C. deep D. old

4. Which of the following may be the author’s best prayer for his two sons now ?

A. I wish them strong wings, with which they can fly higher and touch the sky.

B.I wish them nice fortune so that they can meet people like Dr. Gibbs in the future.

C.I wish them deep roots into the earth since the rains fall and the winds blow often.

D.I wish them great shades under the tree since the sunlight is always sharp and bitter.

5. Which of the following can be the best title of the passage?

A. A Nice Doctor B. The Deep Roots

C. Adversity and Suffering D. My Childhood Memory

When Dr. Gibbs wasn’t saving lives, he was planting trees. His house sat on ten acres, and his life’s goal was to make it a forest.

The good doctor had some interesting theories concerning plant care and growth. He never watered his new trees, which flew in the face of conventional wisdom. Once I asked why. He said that watering plants spoiled them so that each successive tree generation would grow weaker and weaker. So you have to make things rough for them and weed out(淘汰) the weaker trees early on. He talked about how watering trees made for shallow roots, and how trees that weren’t watered had to grow deep roots in search of moisture. I took him to mean that deep roots were to be treasured.

So he never watered his trees. He planted an oak and, instead of watering it every morning, he beat it with a rolled-up newspaper. Smack! Slap! Pow! I asked him why he did that, and he said it was to get the tree’s attention.

It seems that adversity(逆境) and suffering benefit these trees in ways comfort and ease never could. I stood there deep in thought.

Every night before I go to bed, I check on my two sons. I stand over them and watch their little bodies, the rising and falling of life within. I often pray for them. Mostly I pray that their lives will be easy. But I think that it’s time to change my prayer(祷词) because now I know my children are going to encounter hardship.
