It took courage to stand up at work. Now more and more people like to have a change and stand up when they are on something important. Standing up is popular. Medical researchers have found that people who stand at work tend to be much healthier than those who sit.
In the last few years, many office supply companies have begun to sell the adjustable- height desk. These so- called “ sit/ stand” models are equipped with an electric motor that lets them shift from chair height to person height at the push of a button. Unfortunately, they’re regarded as specially furniture. Sit/ stand desks tend to be expensive, hard to find and not easy to test it in person.
When you worked standing up, your mind was more excited and new ideas kept coming out. This is because when you’re standing, you feel a bit unchained from your desk. If you got stuck on a word or sentence as you wrote, you found yourself shaking your arms, bouncing on your feet or stepping away from the desk for a bit------ things you couldn’t do in a chair. Often, standing up seemed to relax your mind enough for you to get over creative barriers.
There’s one other thing about standing for a long time; you tended to get hungrier than you do when you sit on a chair. That felt like confirmation of the stand-up advocates’ belief that you burn more calories when you stand than when you sit. For this reason alone, I’m hoping that sit/ stand desks one day hit the mainstream, with mass- market furniture companies making many low- priced versions. We could all do with a bit more standing up.

| C．can make us relaxed and be creative |
| D．make us move about and unfocused |
| A．free | B．tired | C．uneasy | D．Unbalanced |
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.
