Dr. Albert Schweitzer was a jungle doctor in Africa. He was born in France. He had learned to play the piano since he was five and he was a very good musician. He decided to be a doctor when he was 30 years old. Then he studied medicine for eight years. After that, he asked to be sent to Africa in 1913.

Dr. Schweitzer took big boxes of medicine with him to Africa. He had to go through a lot of dangerous places. At first the new white doctor was not welcome, but soon the people of Africa understood that he was their friend and they helped him build his first small hospital near a river. Many people came to the hospital. Dr. Schweitzer worked day and night.

When he ran out of money and needed more medicine, he would go back to Europe to play music to make money. Then he would return to Africa. Later he built a bigger hospital. He spent most of his life in Africa, not only helping sick people but also teaching the people how to help each other.

During World War I, he was sent to prison. He found that war was more terrible than diseases (疾病 ). When the war was over, he made a speech everywhere to propose (提倡) peace and respect (尊敬) for lives. In 1952, he was named winner of the Nobel Peace Prize.

第十七天

一、美文晨读

Wherever you are, and whoever you maybe, there is one thing in which you and I are just alike at this moment, and in all the moments of our existence. We are not at rest; we are on a journey, our life is a movement, a tendency, a steady, ceaseless progress towards an unseen goal. We are gaining something, or losing something, everyday. Even when our position and our character seem to remain precisely the same, they are changing. For the mere advance of time is a change. It is not the same thing to have a bare field in January and in July, the season makes the difference. The limitations that are childlike in the child are childish in the man.

Everything that we do is a step in one direction or another, even the failure to do something is in itself a deed. It sets us forward or backward. The action of the negative pole of a magnetic needle is just as real as the action of the positive pole. To decline is to accept – the other alternative.

Are you nearer to your port today than you were yesterday? Yes, -- you must be a little nearer to some port or other; for since your ship was first lunched upon the sea of life, you have never been still for a single moment; the sea is too deep, you could not find an anchorage if you would. There can be no pause until you come into port.

二、词汇训练(短语或单词)

1．You must stop the children doing like that ________.

2．________，the hardest problem has been settled and we are one step closer to our goal.

3．Under no ________ will I believe you.

4．There has been a gradual ________ in the population of the town. 5．It took her 20 minutes to ________ to the ticket office. 6．Whole villages were ________ by the earthquake. 7．The terrorists fired into the crowd ________. 8．We moved out of the city ________ in 1989. 9．The discussion ________ three main problems. 10．Your actions ________ your principles.

Lunch hour is crazy at SAME Cafe, the 40-seat restaurant my husband and I run in Denver.

A woman in a（n）_1 suit stepped in. "Hi, Libby．" she said．Wow, what a 2 ! The first time she came to the cafe two years ago, she had no money to pay． 3 many customers, she volunteered to wash dishes and 4 ．Look at her now: confident and hopeful. Wasn't this what we'd hoped for?

In 2003, we'd 5 this crazy dream: start a restaurant with a donation box instead of a cash register（收款台）. Right away we hit hurdles（阻碍）. "There is no such thing as a 6 lunch," one potential landlord（房东） sniffed． I met brokers, bankers and suppliers, only to
