One day a man met Socrates and said, “Do you know what I just heard about your friend?” “1 a minute," Socrates replied. "Before you talk to me about 2 friend, it might be a good idea to take a moment to filter (过滤) what you're going to 3. I call it Three Filter Test. The first filter is Truth. Have you made absolutely 4 that what you are about to tell me is true?" "Well, no," the man said. “5 I just heard about it and ..." "All right," said Socrates.  "So you don't really know if it's true or not. Now, let's try the second filter, the filter of 6. Is what you are about to tell me about my friend 7 good?" "No, on the contrary..." "So," Socrates continued, "you want to tell me something bad about my friend, but you're not certain it's true. You may 8 pass the test though, because there's one filter left - the filter of Usefulness. Is what you want to tell me about my friend going to be 9 to me?" "No, not really." "Well," concluded Socrates, "if what you want to tell me is 10 true, nor good, nor even useful, why tell it to me at all?"

A 16-year-old boy named Li Tao lived in a small town in China. One day, while Li Tao 1 his science homework, he came up with a great idea. He worked out a way 2 a new type of power supply（供应）for his town, which had a problem with its electricity supply.

To make his idea come true, Li Tao began to experiment at home. He believed 3 him from inventing. He made and took apart many models. Even though he faced lots of challenges and failures, he 4 give up. He corrected his mistakes, changed his plans, and kept working hard.

5 two years of hard work, he finally succeeded. He made a small device（设备）that could 6 change wind power into electrical power. This was 7 new, environmentally-friendly way for his town's power problem.

News about Li Tao's invention quickly spread around his school and town, and everyone really took pride 8 his achievement. The group of science-technology of the town decided to help him improve the invention. He 9 to give a speech to encourage other teenagers to learn more about science and be more creative in the Science and Technology Meeting.

His story encourages teenagers that being young is not a barrier（阻碍）to achieve-their dreams. Even a common teenager can do 10 !

Hello, I'm Zhang Xia. I have a good friend. He is English and his name is Jim. Look! This is 1 bedroom. It is a 2 nice room. A clock 3 some pictures are4 the wall. 5 are on the desk. There is a schoolbag on the chair. It's not his schoolbag. It's his sister's. 6 schoolbag is on the bed. Where is7 baseball? It's behind the door. What's that? 8 a cat! Its9 Mimi. It10 a hat.

Florence Nightingale was a nurse and the founder of modern nursing. Her parents gave the name for her because she was born in Florence, Italy. She liked visiting sick people and helping them,{#blank#}1{#/blank#} she often went to the hospitals. She decided to become a nurse so that she could help more people in need. 

In 1853, the Crimean War broke out. She chose to go to a British military (军事的) hospital {#blank#}2{#/blank#} she could take care of the wounded soldiers. What she saw there was terrible, because it was very dirty in the hospital. 

She {#blank#}3{#/blank#} hard so that she could make the hospital clean and save many soldiers' lives. In 1859, Florence wrote several books about nursing so that she {#blank#}4{#/blank#} start the first training school for nurses later. On 13th August 1910, she died. 

Florence Nightingale was a great hero in a special way {#blank#}5{#/blank#} she set a good example for the women in the world. 

Thousands of miles from the Earth, in outer space, is a small planet, Fliptune. It is dark and cold, far from the Sun, behind a much bigger planet. Little green aliens (外星人) live there. They use torches (手电筒) to see. 

One day, a young alien, Neila, put the wrong batteries (电池) in her torch. 

Suddenly (突然), there was bright light. It went up into the sky, around the Sun and reached the Earth. 

The light hit a boy called Billy and his dog. Neila quickly turned the torch off, but the pair were caught by the light. They flew through space and landed near Neila. 

"Hello, " said Billy. Neila smiled. 

"Wow!" said Billy, "Everything's made of ice cream!"

"The ice cream never melts, and nobody eats it. It's too cold here, " said Neila. 

Neila looked sad. "Can you help us?" she said, "We need sunshine to make things grow. "

"No problem, " said Billy, "Can you get us home? I have an idea. "

"Wait there!" said Neila. She got her torch, put the wrong batteries in again——ZOOM! Billy and his dog flew back to the Earth. 

Billy pointed his bedroom mirror (镜子) between the Sun and Fliptune. The sunlight bounced off(弹出) the mirror and up onto Neila's planet. 

Thanks to Billy, Fliptune is not cold any more. Billy moves the mirror every day to keep the sun shining there. Now Neila and her friends sit in the sun and enjoy all the free ice cream.
