I am grateful to my English teacher Susan, at whose help I couldn't have won first prize in the English Talent Competition for high school student last week.
I used to be poorly in spoken English. I was too shy to speak in class. Since she teaches us last term, she has been encouraging him to overcome fear and speak out in class. Thanks to her, I have made great progresses. Besides, I practiced several times in the front of her. It was her advice which made me a better speaker and full of confidence. But I owe my success to her.
Susan set a good example to me. I am determined to become an English teacher when I grow up.

There was a park near my home. But I didn’t go there very often. Many people said there was nothing special. One afternoon I went into the park and found it was really small. I walked quickly because there wasn’t much to see. I walked for some time and found myself standing in front of two paths.1.I found that the two paths were different from each other.
The left one was wide and clean. There were lots of flowers on both sides of the path. Though the flowers weren’t very beautiful, they made me feel good. I decided to take this path. But wait! I looked at the right one. The path didn’t look nice.2.Grass grew everywhere. For a long time I couldn’t make up my mind.
3.It wasn’t nice , but I didn’t want to give up. At last, I came to the end of the path. Ah! There was a small garden there. It was beautiful, perhaps the most beautiful garden I had ever seen.4.
Many people told me that there was nothing much to see in the park. Now I’d like to tell them that if they had followed the right way, they would have felt differently. But when I told them about what I had seen in the park, they just smiled at me without saying a word. I knew they didn’t believe me. They couldn’t even remember that path because it was so small.
5.Don’t be afraid to choose a different path. You may get a big surprise!
A.There is nothing that I want to see.
B.It looked like it had not been cleaned for months.
C.After a while a strange feeling made me follow the dirty path.
D.“ Which way should I go?” I asked myself. I looked at one way, then the other.
E.I told them what happened.
F.My trip to the park that day made me understand something about life.
G.There were trees, flowers and chairs. I thought it was the nicest part of the park.
B
You carry a 1.3 kg mass of fatty material in your head that controls everything you will ever do. This fantastic control center lets you think, learn, create, and feel emotions. It also controls everything your body does. What is this amazing machine? It’s your brain — a structure so amazing that the famous scientist James Watson called it ＂the most complex thing we have yet discovered in our universe＂.
Imagine your kitten jumped onto the kitchen counter, and was about to step onto a hot stove. You would have only seconds to act. In situations like this, your brain reads the signals from your eyes and quickly calculates when, where and at what speed you need to run to save her. Then it tells your muscles to move. No computer can match your brain’s great ability to download, process, and react to the flood of information from your eyes, ears and other sensory organs.
If a bee lands on your foot, sensory neurons(神经元) in your skin send this information to your brain at a speed of more than 240 kilometers per hour. Your brain then uses motor neurons to send a message back to your foot: Shake the bee off quickly! Motor neurons can send this information at more than 320 kilometers per hour!
Your brain contains about 100 billion tiny cells: neurons — it would take you more than 3,000 years if you tried to count them all. Whenever you dream, laugh, think, see or move, tiny chemical and electrical signals are racing between these neurons along billions of tiny neuron pathways. Believe it or not, the activity in your brain never stops. Countless messages fly around inside it every second, like a super-fast game of table tennis. Your neurons create and send more messages than all the phones in the entire world. And although a single neuron generates only a tiny amount of electricity, all your neurons together can generate enough electricity to power a light bulb.

D. Your brains can use neurons to send messages back faster than bees’.
3. The author mentions ＂to power light bulbs＂ (Para. 4) to show __________.
A. neurons can send lots of messages
B. how many active tiny cells brains contain
C. how much electricity brains can generate
D. there is countless information in the brain
4.What is the main idea of the passage?
A. Powerful brain is a wonderful machine.
B. Brains work well in controlling body movements.
C. Brain is the most complex structure in the universe.
D. Human brains are composed of numerous neurons.
