How do you remember the way to your house? Where do dreams come from? It is your brain(大腦) 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 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(天才按鈕)” 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.

l     Use your brain a lot.

(  )51. A British scientist found out that ________ could improve our memories.

    A. drink            B. dreams           C. sleep         D. bananas

(  )52. According to the passage, if we want to have a good brain, we should ________.

A. use our brains more                   B. sleep fewer hours  

C. work longer hours                    D. remember fewer things

(  )53. Which of the following is TRUE according to the passage?

    A. Our brains only work in the daytime.

    B. Our brains need much energy every day.

    C. Smoking can keep our brains healthy.

    D. Getting exercise is good for our brains.

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(傷疤). 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(鋸齒狀的)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(傷口)in the young man’s heart. It fitted, 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.
