After the September 11 terrorist attacks, some high schools in America wanted the students to pledge allegiance（宣誓效忠） to the flag. Is it necessary or not? Let’s see how the kids think of this requirement.

Lea Mouallem, Marymount High School

I believe that saying the Pledge of Allegiance is a way of reminding our country that no matter what happens, we are united. I don’t think our president wants us to go and join the army now, but he wants to tell us that we will be able to overcome the disaster as a whole nation that is working together.

Harry Chin, 15, Culver City High School

I am not for the Pledge of Allegiance and I am not against the Pledge of Allegiance because I just say it so many times that it loses meaning. I say it every day at school in the second period. It doesn’t mean anything any more.

David Tran, 15, Warren High School.

The Pledge of Allegiance is another sign of country. We should have some respect to it. In many schools, we don’t say the Pledge every morning-we just stand up and let the National anthem ring through the silence. We said the Pledge of Allegiance on Sept. 12.

Danny Maryanor, 16, Santa Monica High School

I wonder why we were suddenly asked to recite the Pledge when many of us stopped after elementary school; and the Pledge was recited before the play of “Ode to Joy” （欢乐颂）with recorders. This was not to express patriotism（爱国主义）, or even to remember those who lost their lives on Sept. 11.

I feel I cannot support a nation that in this time of crisis looks outward for revenge（报复）instead of inward for peace. Perhaps we should think more about our problems.

Watch out, Yahoo. There is a search engine out there with super speed and accuracy. It’s very cool.

Google is the Web’s largest search engine. In just two years it has gained a reputation for surprising speed and accuracy, delivering what you are looking for in a second. The site now does this 40 million times a day --- a number achieved without spending a penny on a TV or newspaper ad.

Google doesn’t need them. In the past six months alone, the site has won a Webby (the online version of the Oscar) for technical excellence, set a new record for search engines by indexing a billion Web pages.

Yahoo still has ten times the audience, but Google consistently ranks first in customer satisfaction: 97% of users find what they are looking for most or all of the time. “You see people smile when they use it, like they’ve found something no one else knows about,” says Danny Sullivan, editor of an online newsletter.

No one is smiling more than Larry Page, 27, and Sergey Brin, 26, who seem certain to become billionaires when the company goes public, probably sometime in 2004. they make a great comedy duo(成对的表演者)。When they first met as Ph. D. students, the pair say, they found each other horrible – “I still find him horrible,” adds Brin – but driven together by a computer-science project aimed at coming up with better ways of searching the Web.

The idea behind the Google is that traditional search engines are stupid. They think relevance (关联) is based on repetition; if you type in a request for Tiger Woods, say, you’ll get websites listed according to how many times those words appear. Not only is this no guarantee of quality, but it’s also open to abuse. If you own a Tiger fan site and want to lead more people to it, simply type his name thousands of times in the site’s source code(编码).

1What does the underlined word “them” in the third paragraph refer to?

A. 40 million times              B. Speed and accuracy. 

C. TV and newspaper ads.        D. Web pages

2. Which of the following win greater customer satisfaction?

A. Yahoo        B. Tiger Woods      C. Larry Page     D. Google

3. It can be inferred that Page and Brin ______________.

A. hold very important positions in Google

B. are two ordinary computer programmers of Google.

C. used to hate each other very much

D. hold quite different opinions of computer-science

4. We can learn from the last paragraph that ___________.

A. Google is open to abuse

B. Google remains a traditional search engine

C. Google thinks relevance is based on repetition

D Google is better than traditional search engines

When you are hungry, what will you respond ? Have your favorite meal and stay quiet after that？   1   But it never lets you know，because you keep it busy thinking about your friends or favorite stars．So it silently serves your needs and never lets itself grow．When mind loses its freedom to grow，creativity sets a full stop．This might be the reason why we all sometimes think “What happens next？”, or “Why can’t I think？”

  2   Why reading but not watching TV？It is because reading has been the most educative tool used by us right from childhood．Since it develops other aspects of our life，we have to take help from reading．

When you read a book，of course you run your eyes through the lines and your mind tries to explain something to you．  3   Now this seed is unknowingly used by you to develop new ideas．If it is used many times，the same seed can give you great help to relate a lot of things，which you would have never thought of in your wildest dreams!

This is nothing but creativity． 4   Within no time you can start talking with your friends in English or any other language and never run out of the right words．

So, friends, do give food to your thoughts by reading, reading and more reading． 5   Go and get a book!

A．The interesting part of the book is stored in your mind as a seed．

B．Why not do some reading while you are hungry?

C．Just like your stomach, your mind is also hungry．

D．Now what are you waiting for?

E．Hunger of the mind can be actually solved through wide reading．

F．Reading can help you make more friends, too．

G．Also this makes a significant contribution to your vocabulary．
