浙江之星课时优化作业系列答案I'll never forget the days when I camped (野营) with my classmates last summer.Early in the morning, 200 children from the 4th grade gathered at the bus station. After saying goodbye to our parents, we stood in line to get on the buses. It was more than two hours after we arrived at the campground.
We got off the buses cheerfully like birds flying out of their cages. Laughing and shouting, we jumped and ran all over the place. For us, it was our first time to be away from Dad and Mom. Some started feeling homesick(想家) even before dark. But as the night party and dances began, the homesickness was gone.
The next day, everyone rushed to the boating class, hoping to be at the head of the others. At first, my friends and I worked hard, but the boat wouldn't listen to us and kept going round and round . Then the boating teacher taught us how to work together. After many tries, we did better.
Swimming class was my favorite. It was about one o'clock, the warmest time of a day and the best time to stay in the cool water. The swimming teacher was an interesting man. During the class he often made us shout happily.
A week passed before we knew it. During the week I learned many new things and made many new friends. I also learned to take care of myself without parents around me.

There is a popular belief that goldfish only have a three-second memory. But a 15-year-old schoolboy from Adelaide has just finished an experiment（实验）to tell us that it is not true. He shows everybody that the goldfish is smarter than we think.
“I don’t believe that they had a three-second memory because animals need their memory, so they build up over time a knowledge of where the food is,” said Roy Stokes, a student at the Australian Science and Mathematics School.
He did the experiment in small tank（鱼缸）of goldfish. “I decided to get a bit of red Logo and just feed them next to that. Every day I’d put it in and spread food around it.” He said.
“At first they were a bit scared of it, but by the end of the three weeks, they were actually almost coming before I put the food in.”
After leaving the fish alone for a week, Rory placed the red Logo block in the tank again.
“They remembered perfectly well,” he said.
“They actually had a time faster than the average of the three feeds before I left.”
The goldfish showed that not only could they store information, they also had the ability to get it back as a later date.
Culum Brown, a research fellow at Sydney’s Macquarie University, has studied fish behavior for more than ten years.
He says his studies of Australian native fish show fish were intelligent creatures that know how to avoid enemies and catch food like any other animal.
“The thing that I really liked about Rory’s experiment is he not only got that classical conditioning going but the fact that he could get them next just to that specific coloured market. I thought it was really good.” He said.

A. discussing with his classmates B. making friends with goldfish

2.Rory put a red Logo in the tank to ______.

a. find a tank of goldfish b. feed the fish next to the Logo c. leave the goldfish alone for a week | d. take out the Logo e. put a red Logo into the tank f. put the Logo back into the tank |
A. adbecf B aebdcf C. dabefc D. adebcf
4.What do the last three paragraphs tell us?
A. Rory’s research was highly praised by experienced experts.
B. Rory’s experiment failed to meet the scientific standard.
C. Many scientists had already done the experiment before.
D. Fish are the cleverest animal in Australia.
5.What can we learn from the story?

The following are the posts in an Internet chat room. In this chat room, parents talk about some of the problems they have with their children.

Bay212 | Yes, you did the right thing. White lies are a(n) 76 part of life. Sometimes you have to tell lies that do no harm. Your purpose was to make him feel good. Now he’s ready to play soccer again. |
Bernie | I don’t think there is ever a good reason to lie to our children. Children learn honesty from the 77 they see. As parents, we should be honest in order to teach honesty to our children. Every lie requires five more ties. If you keep hiding truth from them, they will not 78 you. They will not respect you. Honesty is the first step to a good parent-child relationship. |
Missy | You lied to make your son feel better, but you 79 a good chance to teach him a life lesson. People should work hard for what they want. Maybe next time you can say, “No, you didn’t play well today. Great soccer players practice a lot. Let’s go and practice.” The truth will make him 80 and a good soccer player. |
Parvz | Parents should be honest to their children, but they don’t have to tell the whole truth. Next time when your son asks, “Did I play well?” you may say. “What do you think?” Then your son can tell you what he thinks. That way, everything you say is true, and you avoid truth that hurts. |
