Imagine that you are sitting in a park and suddenly remember that you need to send an urgent email. You have your laptop computer with you and you connect it to a wireless access point and access the Internet. Then you send your email. This wouldn’t have been possible if there were no wireless Internet for laptops. Wireless Internet has come into our life in so many ways that we don’t even realize what a necessary part it has become of our day-to-day lives.
How do we connect to a wireless Internet service for laptop computers? There are two ways to do this. They are Wi-Fi connection and Bluetooth connection. Wireless networking is very easy. You just switch on the Wi-Fi button that has been provided in the laptop for Wi-Fi scanning. Once that is done, the computer will connect to the Internet.
An interesting fact about Wi-Fi networking is that you can create a network between similar wireless equipment. Consider a situation where you and your friend both have Wi-Fi laptops, and there is some data you want to exchange. Traditional networking architecture demands that you have a wireless router (路由器). But the beauty of Wi-Fi networking technology is that you can set up a network between you and your friend’s laptop, and share all the data you want.
Broadband (寬帶) Internet connection is typically preferred by any user as it provides better speed for Internet surfing. Up until the invention of 3G mobile phones, Internet speed on mobile phones was very slow. 3G has the promise of changing the entire face of broadband technology. Just imagine browsing at speeds of more that 2MB per second. To give you a measure of the speed, 3G enables you to watch high quality live videos on the Internet.
It is amazing to see how technology changes and the rate at which it changes. There may come a time when you may be able to browse using mobile wireless Internet for laptops anywhere in the world.

閱讀表達（共5小題, 每小題3分, 滿分15分）
Let me tell you about five of the enemies we face from within．The first enemy that you’ve got to destroy before it destroys you is indifference．What a tragic disease this is! “Ho-hum，let it slide. I’ll just drift along．” Here’s one problem with drifting：you can’t drift your way to the top of the mountain．
The second enemy we face is indecision(優(yōu)柔寡斷). Indecision is the thief of opportunity and enterprise．It will steal your chances for a better future．Take a sword to this enemy．
The third enemy inside is doubt．Sure，there’s room for healthy skepticism．You can’t believe everything．But you also can’t let doubt take over．Many people doubt the past, doubt the future，doubt each other，doubt the government，doubt the possibilities and doubt the opportunities．              , they doubt themselves．I’m telling you，doubt will destroy your life and your chances of success．It will empty both your bank account and your heart．Doubt is all enemy．Get rid of it．
The fourth enemy within is worry．We’ve all got to worry some．Just don’t let it conquer you．Instead, let it alarm you．Worry can be useful．If you step off the curb (路邊) in New York City and a taxi is coming，you’ve got to worry．But you can’t let worry loose like a mad dog that drives you into a small corner．Here’s what you’ve got to do with your worries：drive them into a small corner. Whatever is out to get you，you’ve got to get it．Whatever is pushing on you, you’ve got to push back．   
The fifth enemy is overcaution. It is the timid (膽小的) approach to life．Timidity is not a virtue；it’s an illness．If you let it go，it’ll conquer you．Timid people don’t get promoted．They don’t advance and grow and become powerful in the marketplace．You’ve got to avoid overcaution．       
小題1:What’s the best title for this passage? (Within 8 words)
                                                                          .
小題2:List three enemies inside that might prevent you from getting promoted．(Within 5 words)
                                                           .
小題3:Fill in the blank in Paragraph 3 with proper words or phrases．(Within 5 words)
                                                                          .
小題4:Which sentence in the text is the closest in meaning to the following one?
However，you shouldn’t be forced into a small room by the worry beyond control．
                                                                          .

                                                                          .

Teachers and parents usually call attention to the pictures when they read storybooks to pre-school children. But a new study suggests that calling attention to the words and letters on the page may lead to better readers.
The two-year study compared children who were read in this way in class with children who were not. Those whose teachers most often discussed the print showed clearly higher skills in reading, spelling and understanding. These results were found one year and even two years later.
Shayne Piasta, an assistant professor of teaching and learning at Ohio State University, was an author of the study. She says most pre-school teachers would find this method manageable and would need only a small change in the way they teach. They already read story-books in class. The only difference would be increased attention to the printed text. “If you get children to pay attention to letters and words, it makes sense that they will do better at word recognition and spelling.” But she says research suggests that very few parents and teachers do this in a systematic way.
More than 300 children aged four and five were observed in classrooms. They came from poor families and were below average in their language skills. For thirty weeks, the children took part in a program called Project STAR--- Sit Together and Read. The project is based at Ohio State. It tests the short-term and long-term results of reading regularly to pre-school children in their classrooms.
There are different ways that adults can talk to children about print. They can point to a letter and discuss it, and even trace the shape with a finger. They can point out a word and discuss the meaning of the print or how the words tell the story. And they can talk about the organization of the print--- for instance, showing how words are written left to right in English.
小題1:What do we know about the ways pre-school children are usually taught?
A．More attention is paid to the pictures ,with words and letters being ignored.
B．Preference is given to the shape of letters and the organization of the print.
C．The focus of the teaching is on bringing them up to be good readers.
D．Equal attention is paid to the texts and the pictures.
小題2:What does Shayne Piasta suggest pre-school teachers should do in class?
A．Teach children how to draw pictures to get an idea of what they mean.
B．Change the way they teach and pay more attention to words and letters.
C．Adopt different methods according to the students’ difference in reading skills.
D．Read storybooks to children rather than explain the meaning of the pictures.
小題3:Which of the following is TRUE about the study on language skills of pre-school children?
A．Many teachers want to change their way of teaching pre-school children.
B．Attention on the pictures has made the children uninterested in reading.
C．Project STAR aims to research into the results of reading books to pre-school children in the classroom.
D．Teachers are often prevented from taking different approaches to language teaching.
小題4:Which section of a magazine does the passage probably come from?
A．Fashion.B．Economy .C．Entertainment.D．Education.

A sandstorm, also known as a dust storm, is exactly what it sounds like. A very strong windstorm especially in the desert carries clouds of sand or dust that greatly reduces visibility. This wind is usually caused by convection currents (對流氣流), which are created by intense heating of the ground, and is usually strong enough to move entire sand dunes. Air is unstable when heated, and this instability in the air will cause higher winds to mix with winds in the lower atmosphere, producing strong surface winds.
Sandstorms can disturb people’s travel, and can sometimes destroy whole roads, and dry flat areas. Similar dust storms can be found on the planet Mars, and are thought to be seasonal. Today, the destruction of forests and too much farming of farmland can lead to sandstorms. Too much use of water resources can also cause sandstorms.
In the United States of America, sandstorms are rare because of the lack of large deserts and more importantly the development of proper agricultural techniques. The last recorded destructive sandstorm in American history was the Dust Bowl, which occurred on July 16, 1971 and was widely recorded by meteorologists (氣象學家).
To protect themselves from sandstorms, some people wear protective suits. Special equipment can be fixed in some cars to prevent sand from getting into the engine. Sandstorms can cause coughs, and the sand and dust has also been known to carry “infectious diseases”. Sand particles, unlike dust ones, will block air passages, and cause a person who breathes them in to choke. Dust particles may cause an allergic (過敏的) reaction.
小題1:Which of the following plays the first part in forming sandstorms?
A．The instability of the sand.
B．The instability of the wind.
C．The intense heating of the ground.
D．The speed of the wind.
小題2:From the second paragraph, we can learn that at present _______.
A．sandstorms are more often seen on Mars than on Earth
B．sandstorms have led to the lack of clean water resources
C．farming brings more harm than benefits to humans
D．human activities are a major cause of sandstorms
小題3:The author will most probably agree that ________.
A．there will soon be no sandstorms in the USA
B．humans haven’t thought of any way to deal with sandstorms
C．death caused by sandstorms is increasing all the time
D．humans should make more efforts to stop soil turning into desert
