ДАЮ 40 БАЛЛОВ!
Напишите пожалуйста краткий пересказ
I'll never forget Easter 1946. I was 14, my little sister Ocy was 12, and my older sister Darlene 16. We lived at home with our mother, and the four of us knew what it was to do without many things. My dad had died five years before, leaving Mom with seven school kids to raise and no money.
By 1946 my older sisters were married and my brothers had left home. A month before Easter the pastor of our church announced that a special Easter offering would be taken to help a poor family. He asked everyone to save and give sacrificially.
When we got home, we talked about what we could do. We decided to buy 50 pounds of potatoes and live on them for a month. This would allow us to save $20 of our grocery money for the offering. When we thought that if we kept our electric lights turned out as much as possible and didn't listen to the radio, we'd save money on that month's electric bill. Darlene got as many house and yard cleaning jobs as possible, and both of us babysat for everyone we could. For 15 cents we could buy enough cotton loops to make three pot holders to sell for $1.
We made $20 on pot holders. That month was one of the best of our lives.
Every day we counted the money to see how much we had saved. At night we'd sit in the dark and talk about how the poor family was going to enjoy having the money the church would give them. We had about 80 people in church, so figured that whatever amount of money we had to give, the offering would surely be 20 times that much. After all, every Sunday the pastor had reminded everyone to save for the sacrificial offering.
The day before Easter, Ocy and I walked to the grocery store and got the manager to give us three crisp $20 bills and one $10 bill for all our change.
We ran all the way home to show Mom and Darlene. We had never had so much money before.
That night we were so excited we could hardly sleep. We didn't care that we wouldn't have new clothes for Easter; we had $70 for the sacrificial offering.
We could hardly wait to get to church! On Sunday morning, rain was pouring. We didn't own an umbrella, and the church was over a mile from our home, but it didn't seem to matter how wet we got. Darlene had cardboard in her shoes to fill the holes. The cardboard came apart, and her feet got wet.
But we sat in church proudly. I heard some teenagers talking about the Smith girls having on their old dresses. I looked at them in their new clothes, and I felt rich.
When the sacrificial offering was taken, we were sitting on the second row from the front. Mom put in the $10 bill, and each of us kids put in a $20.
As we walked home after church, we sang all the way. At lunch Mom had a surprise for us. She had bought a dozen eggs, and we had boiled Easter eggs with our fried potatoes! Late that afternoon the minister drove up in his car. Mom went to the door, talked with him for a moment, and then came back with an envelope in her hand. We asked what it was, but she didn't say a word. She opened the envelope and out fell a bunch of money. There were three crisp $20 bills, one $10 and seventeen $1 bills-

PART-TIME JOBS FOR TEENAGERS
Part-time jobs for American students are very popular and usually begin during their high
school days. Besides working in fast food restaurants and small cafeterias, a very popular job for a
teenager in America is baby sitting. This has its greatest appeal among teenage girls and a good
baby sitter can earn quite a bit if she is reliable, responsible and mature.
It is not necessarily an easy job and requires both social skills and general competence. Such
a job often involves working on Friday and Saturday nights when many married couples like to
spend the night going to a movie or the theatre.
Other part-time jobs which are popular especially among young boys is managing a paper
route or mowing the lawns of people in one's neighbourhood. These jobs also require a sense of
responsibility and can be a source of good income for a high school student. Young boys who run
paper routes are required to get up early in the morning to deliver the daily news regardless of the
weather. This job has no holidays and requires the newspaper to be delivered every day without
exception. In America there are no newspaper holidays.
Part-time jobs for high schools students in America are often seen as an opportunity to teach
young people about work responsibility and respect for others. The young people learn how to
become part of the adult world and to share in the making of society.-
