The Most Useful Inventions

The Most Useful Invention of All Time?

Barbara－Saturday, April 13

I’m writing a paper for my English class, and I need some ideas. What do you think is the most useful invention of all time? Thanks for your thoughts.

RE: The Most Useful Invention of All Time?

Cindy Wu－Saturday, April 13

There are many－the phone, the car, the bridges, but these are not my choices. For an everyday, useful invention, I vote() for the air conditioner. I live in Hong Kong, and during the summer, the temperature reaches 35 degrees Celsius or more. The heat is terrible! Without air conditioning, people here can not work or study. A lot of people might also get sick without cool air.

RE: The Most Useful Invention: The Internet!

Jorge－Sunday, April 14

The most useful invention of all time is the Internet . We can now communicate with people and do business faster. I own a clothing store in Mexico City. I also have a website. Now, people from all over the world can buy my clothing using my web site. I can keep in touch with friends and family in Mexico and around the world using e-mail. It’s faster than regular mail, and it’s cheaper than using the phone!

RE: The Most Useful Invention: Yes, but…

Kazuo－Monday, April 15

Jorge, I agree－the Internet is useful. But, in my opinion, there is an invention that is the most useful －electricity. Of course, this isn’t a man－made invention, but people like Benjamin Franklin and Alessandro Volta learned how to use it. Without electricity, many of the world’s most important inventions would not work.

1._____ needs some ideas about the most useful invention.

A. Jorge B. Cindy Wu C. Barbara D. Kazuo

2.Cindy Wu thinks the air conditioner _____.

A. is useful in summer B. makes people sick

C. is terrible D. is cheaper

3.Jorge thinks that the Internet is the most important invention because_____.

A. it uses electricity

B. it helps him do business

C. he can buy things from all over the world

D. it is man-made

4.______ is the most useful invention in Kazuo’s opinion.

A. Phone B. Car C. Internet D. Electricity

閱讀短文，根據(jù)短文內(nèi)容回答問(wèn)題

As life-saver Christopher Walsh rescued（營(yíng)救） his brother and then his sister from the water of a canal（運(yùn)河）, his mother shouted to him:” I’m proud of you.”

His mother Berry sat proudly and watched last night as Christopher was given the “Child of Courage‟ award by his favorite TV star.

Christopher was in the car with his mother, father, sister Rosie, and brother Mac, when his father drove into a metal barrier.

The family’s car fell down a hill into the canal, and landed with its wheels up.

Christopher, then , swam through a broken window and got out into the fresh air. Then he saw the rest of his family were still in the car－in the water. He took a big breath and swam back to save first Mac, and then Rosie. Christopher, from England, said:“ I didn’t think about it and only knew I had to get them out. I was frightened, but it was all happening so fast, and I didn’t really think about the danger.”

Christopher freed Mac and then swam back to get non-swimmer Rosie, who was under the cold, cloudy water, in the car.

Christopher had to feel for her seatbelt（安全帶） because he could not see anything. He took the seatbelt off her, then went up for air. Finally he went back to pull her out of the car.

Berry said:“ When I got to the side and looked back, I thought Christopher and Rosie had gone. I thought they were dead. Then I saw him come up out of the water like a dolphin, and I could see he had Rosie. I shouted across the canal, ‘I’m so proud of you. ’”

Christopher’s father was badly hurt in the accident and was taken to a nearby hospital.

1.Was Christopher given the “Child of Courage” award by his favorite TV star?

2.What happened to Christopher’s family?

3.Why did Christopher have to feel for the seatbelt of his sister?

4.Who was badly hurt in the accident?

5.What do you think of Christopher? Why?
