Article: For some years the big drugmakers have been worrying about an approaching "patent cliff"--a fall in sales as the patents on their most popular pills expire or are struck down by legal challenges, with few new potential _ to take their place. This week the patent on the best-selling drug in history expired--Lipitor, an anti-cholesterol pill which earned Pfizer nearly $11 billion in revenues last year.In all, pill like Lipitor with a combined $170 billion in annual sales will go off-patent by the end of 2015. What is supposed to happen now is that lots of copycat firms rush in with "generic" (ie, chemically identical) versions of Lipitor at perhaps one-fifth of its price.Patients and health-care payers should reap the benefit.Pfizer's revenues should suffer. The same story will be repeated many times, as other best-selling drugs march over the patent cliff But generics makers may face delays getting their cheaper versions to market.Ranbaxy, a Japanese-owned drugmaker, struggled to get regulators' approval for its generic version of Lipitor, and only won it on the day the patent expired.More importantly, research-based drug firms are using a variety of tactics to make the patent cliff slope more gently. Jon Leibowitz, chairman of America's Federal Trade Commission (FTC), is concerned by drugmakers filing additional patents on their products to put off the day when their protection expires. Another tactic is "pay-for-delay", in which a drugmaker facing a legal challenge to its patent pays its would-be competitor to put off introducing its cheaper copy. In the year to October the FTC identified what it believes to be 28 such settlements. American and European regulators are looking into these deals. However, legal challenges against them have been delayed, and a bill to ban them is stuck in Congress. To encourage generics makers to challenge patents on drugs, and introduce cheaper copies, an American law passed in 1984 says that the first one to do so will get a 180-day exclusivity period,in which no other...

When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets. The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver's PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car's speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds. Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are "very enthusiastic" about what they're now calling "intelligent speed alert." Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use: "Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving," Paine said. "The system even has the capability to record speeding violations, so parents can monitor their teenage drivers." The product will soon go on sale in Sydney. Question: Which of the following is true of Speed Alert according to Michael Paine? Options: A: Most of the traffic deaths can be avoided. B: Speeding violations can be easily found out. C: The system will excite some teenage drivers. D: The product will not be available for adults.

Read the article and select the best answer. Article: Travelling abroad for leisure is becoming more and more popular for Chinese. The UK is high up in the list of places that the Chinese want to visit. There is a sense of mystery about the UK; it's often the images of England's green parks, countryside and Victorian houses that people point to as an alternative to polluted, overcrowded cities such as Beijing and Guangzhou. The capital is viewed as modern and dynamic, while being filled deep with history. When asked what other images are thought of by the UK, the reply is often "the Queen, tea and Oxbridge". So what's stopping them actually coming? Sebastian Wood ,the British ambassador in Beijing, has described the UK as a _ , and while this is perhaps an exaggeration ,Britain does have a reputation as a country that is harder to access. The main problem for Chinese tourists is obvious. Although visa applications are now completed online, visitors are still required to visit one of 12 UK centers across the country for a face-to-face interview and fingerprinting. If you don't live near one of these enters already, you'd have to travel some distance to get there. Another problem is also to be mentioned. If travelers from China visit the UK, they also want to cover as much ground as possible. But the UK is not included in the Schengen visa, which allows access to a host of 26 European countries such as France and Germany. So it makes the former seem a less worth it. There is also the issue of cost: PS47 for a Schengen visa, PS82 for the UK. On top of this, the UK is viewed as stricter in its handing of visas compared with the rest of Europe, fed by urban legends of rejected applications. In the end, the decision comes down to one question: Is Britain worth a visit? Question: What is the writer's attitude towards visiting the UK? Options: A: He really supports Chinese people to visit the UK. B: He suggests Chinese people visit London strongly. C: He thinks it is troublesome to visit the UK. D: He believes everyone should go to see the Queen and Oxbridge.
