Article: TransLink is urging customers to avoid non-essential travel today and to stay home where possible in the difficult weather conditions. TransLink chief executive officer Peter Strachan said bus and train services were continuing to run where possible, however all CityCat and CityFerry services had been cancelled until further notice. "These are extremely difficult conditions for South East Queensland---we are running essential services where possible but safety remains to be the most important," Mr Strachan said. "Severe weather and associated flooding has impacted on all modes of public transport, with bus, ferry and train services all impacted to varying degrees. "If you are planning to use public transport at anytime over the next few days, then I would recommend you check that your intended service is still running." Service disruptions   for today include: l City network trains running hourly on all lines. l Bus diversions, delays and cancellations in some regions, particularly across Brisbane, Ipswich and the Sunshine Coast. l CityCat and CityFerry services cancelled. Queensland Rail Chief Executive Officer Paul Scurrah said rising waterways had closed some train lines, and road closures and damage to property throughout the South-East had contributed to a shortage of available rail employees. "We intend to run trains hourly on all lines, similar to the timetable we operate on Christmas Day. We will also be looking to run other additional services to meet demand as required. At this stage we will run services stopping at all stations which will depart at the same time on the hour, however, this is all subject to the weather conditions and the availability of traincrew." Mr Scurrah encouraged all customers to visit the Translink website for specific departure times for their station, and asked for patience in the event of delays. "Queensland Rail appreciates that reduced services may cause disruptions but it is simply unavoidable. We have a dedicated and experienced team monitoring the situation around the clock and will be working to reopen the network as soon as practicably possible," Mr Scurrah said. The latest service disruption information is available on the TransLink website www.translink.com.au.

Article: One day, around Christmas time, fishermen off the west coast of Peru started on their traditional fishing trip. Much to their surprise, there were no fish! They knew immediately what had happened. Tales from years gone by had told them this was the result of El Nino which sometimes stop fishing for many months! El Nino is a warm _ that comes and goes along the west coast of South America. It got its name from fishermen in Peru more than a century ago. Every few years, they noticed a sudden warming in the normally cool Pacific water where they fished. Because this warming often came about around Christmas, they called it El Nino, which is Spanish for the "Christ Child". Generally, El Nino occurs every three to seven years and lasts only a few weeks to a month or more. El Nino warms the water it flows through. Because the fish and sea birds need cold water to live, many of them die when El Nino comes through. El Nino also causes both floods and droughts. It is believed that El Nino may have caused the 1993 Mississippi and 1995 California floods. And at the same time, it may have caused droughts in South America, Africa and Australia. El Nino has occurred thirteen times within the last fifty years, bringing natural disasters to many countries such as Indonesia and Peru. However, El Nino does not often trouble China. During this period China was badly hit by El Nino only once. In 1998, North China had a terrible drought, while South China was troubled by floods. 
 Answer: It lasts a few weeks or more.
According to the passage, which of the following is TRUE about El Nino?

Article: A public high school in the rural town of Boonsboro,Maryland,offers a special program recently. Top students in the ninth and tenth grades can attend single-sex classes for math,science,English and social studies. The aim is to help teenagers keep their mind on their work by keeping males and females apart. Rebecca Brown chooses the students for what Boonsboro High School calls the Academy. "What we really want to do is take that top group of kids and take them to the very highest level they can achieve here,so that they're prepared for college," she said. They need high marks and test scores and strong teacher recommendations. They also need to be involved in activities. Michael Bair has been at Boonsboro High School for twenty years and directs the Academy. His ninth-grade English class for boys centers on books that he believes boys find interesting. "The novels they're reading now,are very manly novels. They're novels that deal with the arrogance of man and the pride of man." One of those books,for example,is "The Call of the Wild" by Jack London. This classic story tells of a dog stolen from his home and sold to work as a sled dog in Canada's Klondike Gold Rush. On this day,the students are working in small groups. Vincent and Logan explain why they're drawing pictures that relate to the story. Vincent said,"The main character,Buck,gets abducted , and they send him off to the Yukon in a train. So I'm drawing part of the story where he's in the train. It gets you to _ the setting of the story and gets you to think more about what's going on in the story,the important events of the story."" Instead of just doing work sheets about it,this is a lot more fun," Logan added happily. Morgan Van Fleet likes being in the Academy. She says boys and girls act differently when they are together in a classroom. "To me,it almost seems like it's hindering  your chances at developing yourself because you're more focused on 'Oh,I wish they'd shut up. Oh,what do they think of me?' instead of focusing on what's the homework or what's going on in this class,what's the lesson."
