Article: Down on the beach of Dover,56-year-old Channel swimmer Jackie Cobell bravely set off for Calais.The time was 6:40 am.28 hours and 44 minutes later the exhausted,successful mother from Kent crawled to the shore and walked proudly into the record books.After five years in training,Mrs.Cobell became the slowest person to cross the Channel under her own steam.The previous record for the slowest crossing,set by Henry Sullivan at 26 hours and 50 minutes,has stood for 87 years before Mrs.Cobell started at Dover Saturday morning. She had struggled through changing tides that swept her first one way,then the other.It turned the 21-mile crossing into a 65-mile one.She declared,"Time and tide wait for no man--and they certainly didn't wait for me.I was fully expecting it to get dark before I got to Calais but I never imagined I'd also see the dawn again.But I wasn't going to give up." Her feat raised more than $2,000 in charity sponsorship for research into Huntingdon's disease,a sum that was continuing to grow as news of her achievement spread.That was why she did it."I don't really know myself," she said."I just kept thinking of all the people I'd be letting down if I stopped." Mrs.Cobell took to the water so well at school.But after bringing up two daughters,she started to gain weight.Five years ago she took up swimming again and decided to prepare for the Channel challenge to lose weight.She became much fitter.Then came the big swim."I practiced on Windermere Lake," she said."it's about half the distance of the Channel so I just doubled it,added some extra time,and worked out I could probably get to Calais in about 16 hours." Her husband David,trainer,official observer and friend sailed alongside her on a boat.She said,"I sang to keep myself going.When they told me I was a record breaker I thought they were just having a joke--until I realized it was the record for the slowest crossing.But maybe next time I might be a bit quicker." Question: Why did Mrs.Cobell spend so much time crossing the Channel? Options: A: Because the tides changed her direction. B: Because she was not in good condition. C: Because she wasn't good at swimming. D: Because the winds kept her from swimming fast.

Article: When a consumer finds that something he or she bought is faulty or in some other way does not live up to what the producer says for it, the first step is to present the warranty ,or any other records that might help, at the store of buying. In most cases, this action will produce results. However, if it does not, there are various means the consumer may use to gain satisfaction.A simple and common method used by many consumers is to complain directly to the store manager. In general, the "higher up" the consumer takes his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favour, taking it as true that he or she has a just right. Consumers should complain in person whenever possible, but if they cannot get to the place of buying, it is acceptable to phone or write the complaint in a letter. Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can show clearly what is wrong with what was bought in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example,"The left speaker does not work at all and the sound coming out of the right one is unclear" is better than "This stereo does not work.". The store manager may advise the consumer to write to the producer, if so, the consumer should do this, stating the complaint as politely and as firmly as possible. But if a polite complaint does not achieve the expected result, the consumer can go a step further. He or she can threaten to take the seller to court or report the seller to a public organization responsible for protecting consumers' rights. Question: According to the passage, the last way a consumer has to use is _ Options: A: to write to the producer B: to quarrel with the manager C: to warn the seller to turn to the court or a public organization for help D: to collect several fighters to threaten the seller

But Lee Gray, PhD, of the University of North Carolina, the US, has made it his business to examine this overlooked form of public transport. He is known as the "Lift Guy". "The lift becomes this interesting social space where etiquette is sort of odd ," Gray told the BBC. "They (Lifts) are socially very interesting but often very awkward places." We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, lift users unthinkingly go through a set pattern of movements. He told the BBC what he had observed. He explained that when you are the only one inside a lift, you can do whatever you want--it's your own little box. If there are two of you, you go into different corners, standing diagonally across from each other to create distance. When a third person enters, you will unconsciously form a triangle. And when there is a fourth person, it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle. New entrants to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple--look down, or look at their phones. Why are we so awkward in lifts? "You don't have enough space," Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. "Usually when we meet other people, we have about an arm's length of distance between us. And that's not possible in most lifts." In such a small, enclosed space it becomes very important to act in a way that cannot be construed as threatening or odd. "The easiest way to do this is to avoid eye contact,"she said.

Options: A: remind us to enjoy ourselves in the lift B: tell us some unwritten rules of lift etiquette C: share an interesting but awkward lift ride D: analyze what makes people feel awkward in a lift
