      A long time ago, the monkey and the turtle were good friends. One day, they saw a fallen banana tree and decided to plant it. They divided the tree into two parts. The monkey took the part with leaves, thinking that it would grow faster, then they went home and planted it. Many days passed, the monkeys plant died but the turtle's grew well and produced fruit. When the fruit was ripe(成熟的) the turtle asked the monkey to share it with him. The monkey climbed up the tree and ate all the fruit. So the turtle got angry. He found some sharp sticks and put them around the tree. When the monkey came down, he hurt himself. The turtle laughed and hid himself under a big shell (贝壳). The monkey got very angry and caught the turtle.

  “I'll cut you into pieces,” said the monkey.

  “Good, so there will be many turtles.”

  “No, I'll put you into the fire.”

  “That's better, my skin will be red.”

  “No, I'll throw you into the river.”

  “No,” said the turtle, “I'll die.”

    The monkey threw the turtle into the river, and the turtle swam happily.

How to Study Smarter, Not Harder

    Here are some of our favorite study tips that will help any student study smarter, not harder:

Recite As You Study

    Reciting—saying things out loud should first take place as you read through each paragraph or section. Test yourself. This will help you to understand as well as learn faster because it is more active than reading or listening. It will also help you to notice your mistakes and the topics you have trouble understanding.

Take Fuller Notes

    Notes should be in your own words, brief and clear. They should be tidy and easy to read. Writing notes will help you better than just underlining as you read, since it forces you to rewrite ideas in your own words.

Study the Middle

    The best time to review is soon after you've learned something. You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review.

Sleep On It

    Study before going to bed, unless you are very tired. It's easier to remember material you've just learned before sleeping than after an equal period of daytime activity, because your brain continues to think even after you've fallen asleep.

Combine Memory and Understanding

    There are two ways to remember: by memorizing and by understanding. Multiplication tables, telephone numbers, and math formulas are better learned by rote. Ideas are best learned by understanding.

    The more ways you have to think about an idea, the more meaning it will have; the more meaningful the learning, the better you can remember it. Pay attention to similarities in ideas and concepts, and then try to understand how they fit in with things you already know. Never be satisfied with anything less than a completely clear understanding of what you are reading. If you are not able to follow the thought, go back to the place where you first got confused and try again.
