题型：不详难度：来源：
Put an ice cube from your fridge into a glass of water. You have a piece of string(线) 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers.
You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.
First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt(融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze(结冰) again.
After a minute or two you may raise the piece of string and with it you will raise your piece of ice!
This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don’t put enough salt, the water will freeze again.
小题1:We must use when we carry out this experiment.| A．a fridge | B．some food | C．a table | D．some salt |
小题2:How long will it take to carry out this experiment?| A．More than three minutes. | B．Five minutes or two. | | C．Only one minute or two. | D．About ten minutes. |
小题3:We can learn something about from the passage.| A．physics | B．biology | C．chemistry | D．maths |

Middle school days are both fun and busy. Students spend their days in class, 1 to the interesting or sometimes boring words of their teachers. At break (休息) , they run, play and shout happily . But 2 should students spend their free time after school?

On the first day of school our professor introduced himself and asked us to get to know someone we didn’t know. I stood up to look around when a gentle hand touched my shoulder. “Hi, girl! My name is Rose, I’m 87 years old.”
“Why are you in college at such a young age?” I asked jokingly.
“I always dreamed of having a college education and now I’m getting one!”she replied. Rose became a college symbol(象征) this year and she easily on her from the other students.
At the end of the term we invited Rose to speak at our football party. I’ll never forget what she taught us.
“We do not stop playing because we are old, we grow old because we stop playing. There are only two secrets to staying young, being happy and achieving success. You have to laugh and find humour every day. You’ve got to have a dream. When you lose you dreams, you die!” she said.
“There is a huge difference between growing older and growing up. If you are nineteen years old and lie in bed for one full year and don’t do anything, you will turn 20 years older. If I am 87 years old, and stay in bed for a year, and never do anything, I will turn 88. Anybody can grow older. But every minute counts for young men,” she added.
She ended her speech by singing The Song of Rose. She challenged each of us to study the lyrics and live then out in our daily lives.
At the year’s end, Rose finished the college education she had begun all those years ago. One week after graduation Rose did peacefully in her sleep.

I really love my job because I enjoy working with small children and like the challenges and awards from the job. I also think my work is important. I wasn’t an excellent student because I didn’t do much schoolwork. In my final term I started thinking what I might do and found I didn’t have much to offer.
I then found myself a job, looking after two little girls. It wasn’t too bad at first. But the problems began when I agreed to live in. I would be there if my boss had to go out for business in the evening. We agreed that if I had to work extra hours one week, she’d give me time off the next. But unluckily, it didn’t often work out. I was getting very tired. Because I had too many late nights and early mornings with the children.
One Sunday, I was in the park with the children, and met Megan who used to go to school with me. I told her about my situation. She suggested that I should do a course and get a qualification（资格证书）if I wanted to work with children. I didn’t think I would be accepted because I didn’t take many exams in school. She asked me to phone the local college and they were really helpful. My experience counted for a lot and I got on a part-time course. I had to leave my job with the family, and got work helping out at a kindergarten.
Now I’ve got a full-time job there. I shall always be thankful to Megan. I wish I had known earlier that I could have a success, even if I am not top of the class at school.

There are 365 days in a year. We sleep 8 hours a day, so we have 122 days for sleeping. Then our work time has 243 days left. But there are 52 weekends in a year. Each weekend is two days. We lose another 104 days a year for work. It takes us about one hour to have breakfast and supper. This comes to 15 days over a year. But we can’t work all that time-we need a holiday. Let’s say we have three weeks’ holiday. We don’t work all day. Four free hours each evening takes up 61 days. We have to remember that we get 2 days’ holiday at Easter, 3 at Christmas and 1 at the New Year. There are also 4 Bank holidays. Take those 10 days away and we have 32 days for work. But then we have one and a half hours’ lunch every day, and half an hour’s coffee break. That comes to 30 days a year. This means that we have only a few days left for work every year!
