How to Build Your Own Website

Sixty years ago, people asked about your astrological (星座) sign. 1. These days, having a web address is almost as important as a street address. Your website is an electronic meeting place for your family, friends and millions of people around the world. Best of all, you may not have to spend a cent. The web is filled with all kinds of free services and all it takes is some time and creativity.

2.Like the table of contents of a book or magazine, the home page is the front door. Your site can have one or more pages, depending on how you design it.

While web pages vary greatly in their design and content, most use a traditional magazine layout (编排). 3. Next comes a greeting and a short description of the site. Pictures, texts; and links to other websites follow.

Before you start building your site, do some planning. Think about whom the site is for and what you want to say. 4.

Draw a rough layout on a sheet of paper.

While there are no rules you have to follow, there are a few things to keep in mind:

5. If you aim too high at the beginning, you may never get the site off the ground. You can always add something new to your site.

◆Less is better. Most people don’t like to read a lot of texts online. Break it into small pieces.

◆Smaller is better. Since it takes a long time to download large picture files, keep the file sizes small.

Now it’s time to roll up your sleeves and start building. Learning the net communities helps provide tools to help you build your site.

A. Start simply.

B. A personal website is not usual today.

C. Nowadays, they want to know your website.

D. Pay attention to the contents of your website.

E. At the top of the page is a banner (横幅) GRAPHIC.

F. Next, gather up the material you want to put on the site.

G. Think of your home page as the starting point of your website.

Is it wrong to use someone else’s wireless(Wi-Fi) connection?Just recently,a man was arrested for doing just that.At that time,he was sitting in the street with a laptop(便携式电脑)and using an unsecured(无安全保护措施)wireless connection to surf the Net.What do you think about this topic?Listen to the following different views on it.

For a start,if someone is using your Internet service or downloading,this will affect your speed of access or download limit.Also,it’s bad for Internet service providers.They will suffer in the long run because fewer people will pay for an Internet service if they know they can get it for free.And finally,just imagine this:what if the person who is stealing your Internet connection is involved in an illegal activity?I think the police are totally right to arrest these criminals.

—by Sandra Wilkins

Basically,if the person who paid for the service still has everything they paid for,what’s the problem?It’s just like using the light from streetlamps to read your book,or watching someone else’s firework display.It’s not stealing.

Also,if you leave your wireless connection unsecured,then it is your own fault(过错)if someone else uses it.Just as you wouldn’t leave your front door unlocked,or your car door open,neither should you leave your wireless connection open.By leaving your wireless connection open,you are inviting people to use it.Securing your wireless connection is as easy as clicking a few settings on your router(路由器).And finally,haven’t the police got more important crimes to solve?They’re always saying how they haven’t got the manpower to solve real issues.But this is just ridiculous(荒谬的).

—by James Hoarley

1.Why was the man mentioned in the first paragraph arrested?

A.For stealing someone’s laptop.

B.For surfing the Net in the street.

C.For using an Internet service without permission.

D.For destroying others’ wireless connection.

2.What does Sandra Wilkins think of people using others’ Internet service?

A.He thinks it is necessary sometimes.

B.He thinks it is unacceptable.

C.He thinks it requires good computer skills.

D.He thinks it is good for Internet service providers.

3.In James Hoarley’s opinion, .

A.Internet service should be improved

B.using others’ Internet service is not stealing at all

C.it is hard to secure one’s wireless connection

D.people should leave their wireless connection open

4.What would be the best title for the passage?
