Once there was a huge apple tree. A little boy loved to come and play around it every day. He loved the tree and the tree loved to play with him.
Time went by…the little boy had grown up and he no longer played around the tree every day. One day, the boy came back to the tree and he looked sad. “Come and play with me,” the tree asked the boy. “I’m no longer a kid. I wouldn’t play around the tree any more.” the boy replied. “I want toys. I need money to buy them.” “Sorry, I don’t have money. But you can pick all my apples and sell them. So, you will have money.” The boy picked all the apples on the tree and left happily. The boy never came back after he picked the apples.
One day, the boy returned and the tree was so excited, “Come and play with me,” the tree said. “I don’t have time to play. I have to work for my family. We need a house for shelter. Can you help?” “Sorry, I don’t have a house. But you can cut off my branches to build your house.” So the boy cut all the branches off the tree and left happily. The tree was glad to see him happy but the boy never came back since then. The tree was again lonely and sad.
One hot summer day, the boy returned and the tree was pleased. “Come and play with me!” the tree said. “I am sad and getting old. I want to go sailing to relax myself. Can you give me a boat?” “Use my trunk to build your boat. You can sail far away and be happy.” So the boy cut the tree trunk to make a boat. He went sailing and never showed up for a long time.
Finally, the boy returned after he left for so many years. “Sorry, my boy. But I don’t have anything for you any more. The only thing left is my dying root,” the tree said with tears ①.
“Good! Old tree root is the best place to lean on and rest. Come and sit down with me and rest.” The boy sat down and the tree was glad and smiled with tears ② …
【小题1】----Why did the boy pick all the apples on the tree?
----Because __________.

How do you remember the way to your house? Where do dreams come from?
It is your brain (大脑) that does these things. A British scientist showed that sleep can improve one’s memory. It’s not a dream for students to study when they sleep. In fact, your brain is working day and night. If you learn words before bed, a certain part of your brain may help you to remember the words while you sleep. What’s more, another scientist in the USA found that there was a “talent button(按钮)” in the human brain. It might make a person more talented(有才能的).
There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning（打哈欠）keeps your brain “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
● Eat healthy food.
● Get a lot of playtime or exercise.
● Don’t drink or smoke.
● Use your brain a lot.

【小题1】 A British scientist found out that ________ could improve our memories.

Is the world too crowded? Well, that’s a hard question to answer. It’s all a matter of perspective(视角).In Montana, you might drive for a mile in any direction and not see another human being. In Macao, 60,000 people live in every square mile!
What is true is that the world’s population doesn’t stay the same. It has been increasing at a very fast rate(比例).That’s in part because in each generation(代) these are more people who then have children than in the last generation.
Five hundred years ago, the population of the world was about 460 million. In 1900,the world’s population was under 2 billion(十亿).Right now it is doubling every 40 years. That means, if this rate of growth continues, when you are a parent, there will be twice as many people on earth as there are now. Wow! Now that’s a whole lot of people! Soon the world’s population will probably reach 7 billion. Some people worry about that! But there is a lot of disagreement about just how many people on earth equals(相当于) too many people. But everyone agrees that the more people there are, the more resources(资源) the world needs to feed, house and take care of all of them, and the more need there is to think carefully about how we live and use the earth’s resources.
【小题1】From the first paragraph we can know that ­________.

In life, people come across many experiences, which they remember all their lives. I had a similar experience, too.

It was the day of my last paper of the final exam. My uncle had invited me to spend my vacation with him. I was especially excited about the invitation that my uncle had given me to stay with him for a few days in Cambridge.

On that day we got into our classroom. The teacher quickly handed out the paper. The exam would last two hours and some of the expected questions came. I finished it almost forty-five minutes earlier. But since it was a rule not to collect the paper before the allotted（规定的）time. I had to sit till the teacher collected the paper. I checked my paper twice and corrected some of the mistakes in it. I started thinking about the place my friends and I had planned to go to after the exam. The time seemed to be endless. So I thought of drawing something on the paper and turned it overleaf. I was shocked to see that the page which I had supposed to be blank had four more questions on it which carried 20 marks and would take at least half an hour to complete. There were only 10 minutes left. I was so nervous that I could hardly write anything. They were the sub-questions（小题）of the last question. Suddenly our physics teacher came in and told all of us that in the last question, out of 6 sub-questions only 2 had to be solved. I felt very relieved.

From then on, I realized that my anxiousness and excitement could have cost me to lose 20 marks and decided never to make such a mistake again.
