Vicky Zhao is a mainlander working in Hong Kong. For her, one thing she can't put up with is people standing on the wrong side of the escalator  in subway stations. "Escalators help us move faster and save time. It isn't a place to rest," the 24-year-old says. "I often see tourists block the way with their suitcases or chatting on the escalators during rush hours. _ annoys me to no end." Admitting she is not the patient type, Zhao says things are much better in Hong Kong than in cities on the mainland where "stand right, walk left" signs are often ignored. The logic behind the "stand right, walk left" escalator etiquette  seems obvious. Even though you may want to catch your breath while you're transported up or down, you should still consider others and leave enough space for people in a hurry, so that they can run and catch the train. Many cities' escalators, including London's and Beijing's, use the "stand right, walk left" system to speed up the flow of people. (Australia is an exception and you should stand on the left side instead.) But some cities discourage people from moving on escalators out of safety reasons. In Hong Kong's subway stations there are regular announcements asking people to "stand still" on escalators. Even so, most people in thisfast-paced cityobserve the "stand right, walk left" etiquette. But the people who stand on escalators defend themselves by telling the walkers not to be so impatient. The BBC quotes one stander as saying: "If the person is in such a rush, why not just take the stairs? Even when the escalator is packed and there's nowhere to move, I see these same people complaining about not being able to pass." Whatever the escalator etiquette is in the place you live or visit, do what most people are doing and always be mindful of others: leave enough space between each other, don't stay at the end of the escalator, and if someone is blocking... Question: Which of the following statements is the writer's opinion? - People should stand right no matter where they are. - People should do as the Romans do and consider others. - People should do as they like on the escalators. - People should be seriously criticized when they block the way.
People should do as the Romans do and consider others.

This age-old strategy has worked well for Real Networks, Microsoft's main competitor in multimedia software for the Internet. Now, the smaller Seattle-based firm is trying a novel way to contain the software giant. On October 29th, it released the underlying recipe, or source-code, of its RealPlayer software and will soon do the same for its other programs--giving away a big chunk of its intellectual property . This may sound like a desperate echo of 1998, when Netscape, struggling in Microsoft's chokehold, published the source-code of its web browser. Yet Real Networks is not playing defence. It is trying to encourage the creation of a common multimedia software infrastructure for every kind of file format and device, thus thwarting  Microsoft's ambitions in this promising market. The firm hopes that others in the industry (volunteer programmers, media firms and hardware makers) will take the code, called Helix DNA, improve it and make it run on new devices, such as mobile phones and home stereos, turning Real Networks' software into an industry standard. Clever licensing terms are supposed to ensure that this standard does not splinter and  that the firm still makes money. Individual developers, universities and other non-profit organisations can modify the software as they please, and even redistribute it for free, so long as they also publish the source-code for their changes. This is a sort of payment in kind, for Real Networks is then allowed to use these contributions. Firms, on the other hand, must pay royalty fees if they distribute more than 1m copies of the code. They also have to make sure that their software works with other Helix DNA products. The software's development community already has 2,000 members. And several hardware makers back the effort. But there are risks. Afraid of piracy, media groups are suspicious of anything that might be related to hackers. The self-created competition could also hurt Real Networks if customers decide its commercial products, which... Question: Which of the following can be a disadvantage of releasing the source-code? - It can bring about self-created competition. - It can defeat Microsoft's ambitions in this market. - It can use the improved software. - It can get royalty fees from some firms.
