On a hot summer day, there are few things that are more wonderful than a nice cool pool.

    {#blank#}1{#/blank#}And it is completely relaxing. Of course, if you have children, there are certain measures you should take to keep them safe, whether you have a pool in your backyard or you are going to a public pool.

    People should never swim by themselves. Actually it only takes a second for people to become injured and drown(溺水). {#blank#}2{#/blank#}This is especially true for young children.

    Splashing(玩水) is fun, but don't take it too far. {#blank#}3{#/blank#}Kids love to go after one another through the water and to splash and jump around. But it is important to teach children not to jump on top of one another and to watch their surroundings in the water, so that they do not accidentally knock into others.

    If you have a pool, you must have a locking gate around your pool. {#blank#}4{#/blank#}Keep the gate knocked at all times, even when you are in the pool.

    Know the way out. {#blank#}5{#/blank#} Make sure that they know where all ladders are and how to enter and get out of the pool properly. Although your children may be able to lift themselves out of the pool using the side, that is not the safest way to go.

A.Kids should be taken good care of when they are swimming in the pool.

B.This is to prevent children from entering your pool without your knowledge.

C.And having someone there with you can make the difference between life and death.

D. Be sure to show all children the proper way to get out of the pool.

E.Even so, attempt to avoid getting any pool water into your mouth.

F. Jumping into the water seems like the perfect way to deal with the heat.

G. .Playing around in the pool can be a lot of fun.

    Ebola is a dangerous virus that can cause people to get very sick and even die. The virus is causing the biggest problems in western Africa, where it has spread quickly. {#blank#}1{#/blank#} But it can get worse and cause life-threatening symptoms(症状), such as bleeding and trouble breathing.

    {#blank#}2{#/blank#}

    Ebola does not spread like colds or the flu because it does not float through the air. Ebola also doesn't spread through food or water, like some other viruses. Instead, Ebola spreads when someone touches the body fluids(液体) of a sick person.

    {#blank#}3{#/blank#}

    An outbreak is when many people are getting sick with the same illness around the same time. You may have heard of a flu outbreak, which is when lots of people get sick from the same types of flu virus. When an outbreak happens because of a virus, more people could get sick because there is a lot of that virus around.

    Where did Ebola come from?

    Scientists aren't sure how the first person gets Ebola at the start. {#blank#}4{#/blank#}Tropical animals in Africa believed to carry the virus include great apes, chimpanzees, gorillas, monkeys, fruit bats, porcupines, and forest antelopes.

    What do kids need to do about Ebola?

    Ebola is making many people sick in Africa, but no matter where you live, it's always a good idea to wash your hands well and often. {#blank#}5{#/blank#}

A. How do people catch Ebola?

B. But they think that people may pick up the virus by touching or eating infected animals.

C. Why do I need to wash my hands?

D. It's very important that infected people get treatment right away.

E. Ebola symptoms can start with fever and headache, kind of like the flu.

F. What is an outbreak?

G. Keeping hands clean can help protect you from common illnesses like colds and the flu.

    My teacher, Mr. August J. Bachmann, was the most influential teacher I ever had.

    I had gotten into trouble in his class: Another student had pushed me for fun, and I became angry and began to hit him. Mr. Bachmann stopped the fight, but instead of sending me to the office, he sat me down and asked a simple question, "Penna, why are you wasting your life？Why aren't you going to college?"

    I didn't know anything about colleges or scholarships. No one had ever considered that a fatherless boy from the poorest neighborhood had a future. That day, instead of rushing off for lunch, he stayed and explained possible education options to me. At the end of our talk, he sent me to see a secretary who had a child at a state college. This was in 1962 at Emerson High School in Union City, New Jersey.

    Well, 55 years have passed, and what have I done with the knowledge he gave me？I gained a PhD from Fordham University when I was only 29.I taught English and social studies and then moved up the chain of command from teacher to principal(校长).

    I've sat on the board for Magnet Schools of America and represented that organization at the United Nations. I've won a number of great educational awards. But where would I be if a truly caring teacher had not taken the time out of his lunch period to speak to me? It was without question only his confidence in me that helped me forward.

    I have repaid his kindness hundreds of times by encouraging misguided youngsters to aim higher. If I have saved any children, it is because of him. If I have been a successful educator, it is because I had a great role model in Mr. Bachmann.

    Daniel stays home on workdays. He starts his personal computer in order to connect with the office which is about three hundred miles away in another city. After work, he puts on his headphones, watches a movie on his home video recorder, or plays baseball on the computer. On many days, Daniel doesn't talk to any other human beings, and he doesn't see any people except the ones on television. Daniel is imaginary, but his lifestyle is very possible. The inventions of modern technology seem to be cutting us off from contact with our fellow human beings.

    The world of business is one area in which technology is separating us. Experts say, for example, that many people will soon be able to work at home. With access to a large central computer, employees such as office clerks, insurance agents, and accountants could do their jobs at display terminals (终端) in their own homes. They would never have to actually see the people they're dealing with. In addition, the way employees are paid will change. Workers' salaries will be automatically paid into their bank accounts, making paper checks unnecessary. No workers will stand in line to receive their pay or cash their checks. Personal banking will change, too. Customers will deal with machines to put in or take out money from their accounts. Many companies and consumers have already changed the way they sell or buy products. E-commerce, or business done on the Internet, is becoming more and more popular. This, therefore, makes it possible for people to do shopping without going out of their homes.

    Another area that technology is changing is entertainment. Music for example, was once a group experience. People listened to music at concert halls or in small social gatherings. For many people now, however, music is an individual experience. Walking along the street or sitting in their living-rooms, they wear headphones to build a wall of music around them. Movie entertainment is changing as well. Movies used to be social events. Now, fewer people are going out to see a movie. Many more are choosing to wait for a film to appear on television or are borrowing videotapes to watch at home. Instead of laughing with others, viewers watch movies in their own living-rooms.

    Many years ago, my mother read from the book Blueberries for Sal by Robert McCloskey to me. I remember as if it were yesterday, hearing her voice at my side on a cold wintry night. My mother's voice changed my world.

    Long before I could read on my own, she shared with me the strength and beauty of McCloskey's language a story of a little girl and her mother out in nature, co-existing with a mother bear and her own baby. The power of the story, of language and of my mother all came together. And it happened many times after that, over and over. The read aloud made me a reader.

    Years later, I was reading aloud a picture book to a small child in a classroom. His life, so far, had not been easy. His childhood was troubled by poverty and loneliness. In that moment, in the joy of the read aloud, he had an idea that started something big.

    What he said was this: "Mrs. Allyn, let's make sure everyone knows how good this feels. Let's have a holiday for the read aloud" Therefore, my organization, LitWorld, created a grassroots movement World Read Aloud Day in 2010 to honor this young boy's wish for everyone to be able to have a read aloud every day.

    Since the day he shared that good idea with us, World Read Aloud Day has become a worldwide event reaching over one million people in more than 65 countries around the world. This year we are over 600 cities strong, a number that is growing every day.

    Children who grow up as readers become engaged citizens of the global world, and every child deserves the right to read. When I say that reading aloud will change the world, I know it sounds simple. But one of the many great things about giving kids access to the power of stories and sharing them together is that it is simple. It is also cheap and easily done. And the impact is huge.
