Andrew Ritchie, inventor of the Brompton folding bicycle, once said that the perfect portable bike would be “like a magic carpet…You could fold it up and put it into your pocket or handbag”. Then he paused: “But you’ll always be limited by the size of the wheels. And so far no one has invented a folding wheel.”

It was a rare — indeed unique — occasion when I was able to put Ritchie right. A 19th-century inventor, William Henry James Grout, did in fact design a folding wheel. His bike, predictably named the Grout Portable, had a frame that split into two and a larger wheel that could be separated into four pieces. All the bits fitted into Grout’s Wonderful Bag, a leather case.

Grout’s aim: to solve the problems of carrying a bike on a train. Now doesn’t that sound familiar? Grout intended to find a way of making a bike small enough for train travel: his bike was a huge beast. And importantly, the design of early bicycles gave him an advantage: in Grout’s day, tyres were solid, which made the business of splitting a wheel into four separate parts relatively simple. You couldn’t do the same with a wheel fitted with a one-piece inflated （充气的） tyre.

So, in a 21st-century context, is the idea of the folding wheel dead? It is not. A British design engineer, Duncan Fitzsimons, has developed a wheel that can be squashed into something like a slender ellipse （椭圆）. Throughout, the tyre remains inflated.

Will the young Fitzsimons’s folding wheel make it into production? I haven’t the foggiest idea. But his inventiveness shows two things. First, people have been saying for more than a century that bike design has reached its limit, except for gradual advances. It’s as silly a concept now as it was 100 years ago: there’s plenty still to go for. Second, it is in the field of folding bikes that we are seeing the most interesting inventions. You can buy a folding bike for less than £1,000 that can be knocked down so small that it can be carried on a plane — minus wheels, of course — as hand baggage.

Folding wheels would make all manner of things possible. Have we yet got the magic carpet of Andrew Ritchie’s imagination? No. But it’s progress.

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).

Teachers say the digital age has had a good influence - and a not-so-good influence - on this generation of American teenagers．More than 2,000 teachers took an online survey．Three-quarters of the teachers said the Internet and digital search tools have had a "mostly positive" effect on their students' research habits and skills．But 64 percent said the technologies "do more to distract（使 - - - ---分心） students than to help them academically．" And 87 percent agreed that these technologies are creating an "easily distracted generation with short attention spans．"

The Pew Internet Project did the survey with the National Writing Project．Judy Buchanan is the vice director of the National Writing Project and a co-author of the report．Ms．Buchanan says digital research tools are helping students learn more and faster．"Teachers really favor these tools because they are ways to make some of the learning exciting and engaging．Young people favor these tools．The goal is to really help them become creators of meaningful content, and not just sort of consumers．"

But one problem the survey found is that many students lack digital literacy．They trust too muck of the information they find on the Internet．Judy says these students haven't developed the skills to determine the quality of online information．"It's something that really has to be taught and paid attention to．Because in a world in which things happen quickly, you do need to step back, reflect and analyze the information you have．"

Another problem is blamed on something that might not seem like a problem at all: being able to quickly find information online．Teachers say the result is a reduction in the desire and ability of their students to work hard to find answers．They say students are overly dependent on search engines and do not make enough use of printed books or research libraries．

Many teachers are also concerned that the Internet makes it easy for students to copy work done by others instead of using their own abilities．

D．students can't judge online information properly

4.Some students don't tend to work hard because

A．they can get answers on the Internet quickly

B．printed books and libraries around aren't enough

C．the Internet can't make students concentrate

D．they can copy each others' work without being punished

Why Rent Textbooks?
Renting textbooks is a relatively new idea for everyone. Back in the old days, the idea of renting one never existed since the books are affordable or readily available in libraries. But the time has changed and with the changes in educational system and various economic challenges happening across the globe, the price of textbooks increased.
Given such fact, textbook renting is now a new fashion among college students. Research was made to find out if renting helps one save money and time rather than buying new textbooks and realized that it really is. Let’s examine carefully further and see why renting books is a cost-effective way to still get to have your textbooks without shelling too much money from your pocket.
Gives value for your money
You don’t have to buy all of your textbooks. Those non-major subjects, are better acquired through renting. It saves one money and helps you give out the money you save on some other personal possessions you need in college.
Renting textbooks allows you to save at least 50% off the standard retail (零售) price for each item. You can tell, with a little research, that renting is a lot cheaper compared to buying used books aside from looking way better than the former.
Saves time
You can save a great deal of time when renting a textbook. Instead of browsing your way for hours trying to look for better deals online, you can simply go to a popular book renting marketplace online and just order away. There is literally no need to skimming for hours and see where you can find a great deal. Often, the rental company gives you prepaid postage slip just to get you going and do the same when you decide to return the book.
This process not only saves you time, it also saves other resources like gas if you decide to go to the nearest bookstore to buy books or spend hours using electricity just to find a good deal.
User Friendly
Aside from being able to save money and time, renting textbooks brings convenience to all users. Imagine trying to scan the virtual bookshelf and checking on comments of previous users and figuring out which ones got bad comments and which had great ones. It could be fun at first but if you are short of time, the process can become annoying.
If you rent books, you will only be needing the book’s ISBN number and find it right away. No more time-wasting site search. Type in the ISBN number, order the book, and wait for it to get shipped to your home.
【小题1】The reason why people haven’t the habit of renting textbooks in the old days is that ______.
