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 slee
p. In fact, your brains is working day and night. If you learn words before bed, a certain part of the 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(天才按钮)” in the human brain. It might make a person more talented.
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 our brains “cool”, which makes us think quicker.
Here are some pieces of advice to keep a good brain:
l Eat healthy food.
l Get a lot of playtime or exercise.
l Don’t drink or smoke.

Once upon a time, a young man was standing in the middle of the town announcing that he had the most beautiful heart in the world. A large crowd gathered, and they al praised his heart for it was perfect.
Suddenly, an old man appeared and said, “Why ,your heart is not as beautiful as mine.”
The old man’s heart was ful of scars（伤疤）. Some pieces of his heart were removed and some pieces from other people were put in, but they didn’t fit quite right. So there were several jagged（锯齿状的）edges. In fact, there were stil some holes in his heart where the pieces were missing.
The young man laughed,“Comparing yours with mine, mine is perfect and yours is a mess.”
“Yes,”said the old man. “But, every scar shows that I took out a piece of my heart and gave it to a person, and often he gave me a piece of his heart in return.”
“Why do you have some jagged edges in your heart?”asked the young man.“Because the shapes of the pieces weren’t the same.”“Then the holes?”“Sometimes I gave pieces of my heart away, and the other person hasn’t given back a piece of his, so … but I don’t care.”“How come?”“They remind me of the love we shared.”
The young man was deeply moved. He walked up to the old man, took a piece of his heart out and gave it to the old man.
The old man placed it in his heart, then took a piece from his old scarred heart and placed it in the wound（伤口）in the young man’s heart. It fitte
d, but not perfectly, as there were some jagged edges.
The young man looked at his heart, not perfect any more but more beautiful than ever.
How sad it must be to go through life with a whole untouched heart!

As we all know, the environment around us is getting worse and worse. In some places we can’t see fish 26 in the river or trees on the hills. Some people even have no clean water to drink.
Recently, a new lifestyle called low carbon life is 27 every comer of our country. The meanings of low carbon are 28 energy and no waste. It is such an important project that I can’t wait 29 my ideas on how to promote it.
First，we should 30 a no-car day every week in our school. Because cars not only cause serious air pollution but also waste energy. 31 the no-car day, neither students 32 teachers are allowed to drive to school. At the same time，just walk or run. Use our 33 and enjoy the fun.
Second, we had better not use plastic bags 34 . No one can stand the “white pollution”， 35 it is wise to use cloth bags which can 36 again and again.
37 ，one thing 38 we should keep in mind is that every big thing comes from the small details. So, as students, we ought to turn 39 the lights the moment we leave, use 40 sides of the paper, and reuse our textbooks and so on.
All in all, it weighs greatly for all of us to put the low carbon lifestyle into practice. Just set our mind to these：no-car days, no plastic bags, and no waste. Let’s do it now.
