At first, joining the Blue Sox didn't（1） ______ Leah's feelings about sports. She went to the practices every week, but she didn't take them seriously. No matter how（2） ______ she played, Leah didn't get discouraged. She didn't want to become a star player. She was just there to have fun with Anna.

Believe in Yourself Anita was an active girl who grew up in the eastern of Nepal. Her parents were shepherds. It was that point of the year when the sky was blue, the sun smiled upon the village and so the stars in the dark never looked brighter before. Anita found a lot of tourists visit her village. Watching people all over the world visit her village made Anita curious. "What are these people doing here, father？" asked Anita. Anita's father laughed and said, "Darling, they have all come to climb those mountains."
Amazed at their courage, Anita said, "Really, father？ Is it possible to climb to the top？ "
"Of course dear," replied her father, "Many people do it. "
"Someday, I will be able to climb to the highest of these mountains." said Anita with a burning dream brewing（酝酿）in her eyes. But life had other plans for her. Anita had a terrible accident when she was thirteen. Unluckily, she lost one leg. Clouds of hopelessness darkened her happy world.
"I will never be ready to climb those mountains!" cried Anita.
Her father loved her dearly. He couldn't see his little girl in pain. He was extremely sad. But he did not lose heart. He thought over and over and he couldn't sleep well. Finally, he had a good idea.
One day Anita's father built her a wooden leg, which she could wear and walk. "Never say 'never'. Start climbing the mountains." said the determined father.
Anita was beside herself with joy. She wore the wooden leg and walked, and fell. Stood up, and tried to run, and fell again. The whole village laughed at the daddy and daughter's foolishness. But nothing pulled them down. Both the father and daughter were determined to win against all the odds. They kept practising.
After five years, Anita made it to the highest of the mountains. And she made her father very proud of her, along with her country.
24. What made Anita curious？ ______
A. Burning dream brewing in her eyes.
B. Watching the stars look brighter before.

25. Anita ______ when she was thirteen.

My friend, Robert, has a twin sister named Amanda. Though they get along well, there are some things about Amanda and her friends that puzzle Robert. He can't understand how girls can talk for so long. For example, sometimes when he leaves home to play football, Amanda and her friend, Sharon, are sitting on the sofa, talking. When he comes back three and a half hours later, they're still sitting on the sofa, continuing the same conversation on the same topic. One day Robert was so curious that he asked Amanda what they talked about, but she replied, "We're best friends. We talk about almost everything-film stars, pop songs, recipes, everything!"
Boys and girls have different attitudes towards friendship. Friendships between girls are usually based on shared feelings and support, but friendships between boys are based on shared activities or interests. A boy is likely to be careful about sharing his feelings with his close friends. A girl's closest friend, however, might be eager to tell her about something that has happened in her life.
Many studies worldwide show that girls have more friendships than boys. In fact, many teenage boys cannot name a single best friend. When asked, they hesitate before answering, "My best friend？ I can't think about that. I am busy with my homework, and I have so many different friends that it is hard to choose just one best friend."
Girls who have been asked can usually answer the question without pausing, "A best friend？ Of course. We have a lot to share with each other. We do a lot of things together such as talking and shopping."
We have to realize： boys share activities, while girls share feelings. The qualities that boys and girls consider important in a friend seem to be the same, regardless of（无论）the basis of these friendships. The important thing to remember is that both of them are friendships. We all need friends in our lives.
27. Robert wonders ______ .
A. why Amanda and her friend talk so long
B. why girls answer the question with pausing
C. what attitudes girls have towards friendship
D. what Amanda and her friend were curious about
28. The word "hesitate" in Paragraph 3 probably means " ______ ".
A. are slow to speak B. are shy to speak in public
C. share feelings secretly D. are eager to tell the answers
29. What do you know about friendships from the passage？ ______
A. Boys and girls both make sure what friendships are.
B. Friendships are the most important among girls and boys.
C. Girls like to share their attitudes to friendships with friends.
D. Boys and girls have the same idea on the qualities in a friend.
30. Which is the best title for the passage？ ______
A. Teenagers' Friendships
B. Different Attitudes towards Friendships
C. The Qualities of Friendships
D. Everybody Needs Friendships
Q

Everything in our body needs water to work! But sadly, not everyone has access to clean drinking water. In the US， for example, a lot of people living in the countryside get their water from wells and springs-and it can have bacteria in it.
If you drink water with bacteria in it, you might get very sick-some people even die. That's why people living in the countryside need to clean their water before they drink it. There are a few quite efficient ways to do this. But all of them have at least one disadvantage. Iodine tablets（碘片） have negative side effects on your body if you use them for too long. Ultraviolet（紫外线的）lamps use a lot of energy and filtration（过滤）systems are expensive.
Therefore, we wanted to use a simple energy source. Everyone nowadays carries with them： a smartphone! What if we could clean water with such a common device？ Wouldn't that save a lot of trouble？
We designed a downloadable app and a cheap device that can be plugged into a smartphone to disinfect（杀毒）water（Figure. 1）.
The method that our device uses is called electrochemical disinfection. It uses electric currents（电流）to produce substances that can kill bacteria. In our experiments, we used a smartphone to produce the electric current and copper（铜）wires as a source for the antibacterial substance. Copper ions（离子）are released from the copper wire. These copper ions kill bacteria.
Copper can also be dangerous for humans but only in much higher concentrate. We tried to find the perfect balance： where just enough copper ions are released to kill the bacteria, without reaching a harmful level for humans.
With our new device, we were able to kill almost all bacteria in the treated water. Although our device worked really well, we only tested it in a limited laboratory setting-so some things could be different in real life.
We were able to clean three liters（or 8 cups）of water by only using less than 1% of the phone's battery. However, the disinfection of these three liters took about five hours-which is too long.
Still, all of our tests suggest that it is possible to improve the speed of our device quite easily. When this is done, anyone with a smartphone can use our device to disinfect their drinking water.
Hopefully, our device will be ready for everyday use very soon!
31. What can we learn from the passage？ ______
A. Copper ions can clean the water by killing bacteria.
B. Everyone in the US can afford the filtration system.
C. Cleaning water with phones uses less battery and time.
D. It's safe to use iodine tablets to clean water for a long time.
32. The writer probably agrees that ______ .
A. the device will be put into use very soon
B. it's safe to drink water with lots of copper ions
C. it's easy to improve the speed of the smartphones
D. the smartphones have been used to disinfect water widely
33. What is the passage mainly about？ ______
A. Why teenagers love using smartphones
B. Why smartphones benefit us in daily life.
C. How you can use smartphone wisely in daily life.
D. How your smartphone can make water safe to drink.
34. The Story of Braille
Usually, when we talk about reading, we think of using our eyes to see letters written in ink on paper. However, this is not always true. For example, blind people cannot see, but they can still read books.
The man who introduced blind people to reading was Louis Braille（1809-1852）. Braille lost his eyesight at the age of three as a result of an injury. When he was ten, he went to a school for the blind in Paris. In those days, books for blind people used paper pressed against metal wire to form letters. Since the metal wire was heavy, each book weighed as much as 100 pounds. The whole system was not convenient for use. Indeed, the school library only had fourteen such books in it.
In 1821， a soldier visited the school and showed the students a system for passing messages at night during times of battle. His system used paper with small, raised dots that could be felt with the fingers. Each letter of the alphabet was represented by a different pattern which consisted of twelve dots. The soldiers would drag（缓慢地移动）their fingers over the raised dots to read the message.
While the students found the soldier's idea interesting, the system was too difficult to be of practical use. However, young Louis Braille took the idea and worked on it. At the age of fifteen, he created a system with patterns of six raised dots representing each letter. "Braille"， the system for reading used today by blind people around the world, was thus born.
The blind can easily recognize Braille with the fingers. They can also easily write in Braille with a special typewriter. Today, it is the most common system used by blind people for reading and writing, and nearly every language, including Chinese, has its own version of Braille for its people to use.
(1) Who introduced blind people to reading？
______
(2) When did a soldier visit the school and show the students a system？
______
(3) How old was Louis Braille when he created a system？
______
(4) Does the system "Braille" include Chinese？
______
(5) What can you learn from Louis Braille？
______
