Article: A good joke can be the hardest thing to understand when studying a foreign language. As a recent article in The Guardian newspaper noted, "There's more to understanding a joke in a foreign language than understanding vocabulary and grammar." Being able to understand local jokes is often seen as an incredible ice-breaker for a language learner eager to form friendships with native speakers. "I always felt that humor was a ceiling that I could never break through," Hannah Ashley, a public relations account manager in London, who once studied Spanish in Madrid. Told The Guardian, "I could never speak to people on the same level as I would speak to a native English speaker. I almost came across as quite a boring person because all I could talk about was facts." In fact, most of the time, jokes are only funny for people who share a cultural background or understand humor in the same way. Chinese-American comedian Joe Wong found this out first-hand. He had achieved huge success in the US, but when he returned to China in 2008 for his first live show in Beijing, he discovered that people didn't think his. Chinese jokes were as funny as his English ones. In Australia, meanwhile many foreigners find understanding jokes about sports to be the biggest headache. "The hardest jokes are related to rugby because I know nothing about rugby," said Melody Cao, who was once a student in Australia. "When I heard jokes I didn't get, I just laughed along." In the other two major English-speaking countries, the sense of humor is also different. British comedian Simon Pegg believes that while Britons use irony-basically, saying something they don't mean to make a joke-every day, people in the US don't see the point of using it so often. "British jokes tend to be more subtle and dark, while American jokes are more obvious with their meanings, a bit like Americans themselves," he wrote in The Guardian. Question: From the article, we can learn that _ . Yes or no, is the answer "not all English native speakers can understand English jokes easily"?
Yes

Article: . As the world's largest terrestrial carnivore ,the polar bear is the king of the great white north. Adult males can measure more than 9 feet in length and weigh between 770 and 1,430 pounds. The bear's body and neck are elongated, and the head is narrow and long with small, rounded ears. Polar bear populations can be found in northern Canada, Greenland, Norway and Russia, and there have been reports that polar bear tracks have been found as far north as the North Pole. The 5,000,000-square-mile range of the polar bear circles the Arctic and contains stretches of open water where seals are easily caught. Polar bears live on the annual Arctic sea ice that provides a platform from which they can hunt. They hunt seals on the sea ice by breaking into seal dens in the sea ice. The dens aren't visible from above,but seeing is less important than smelling to a polar bear -- with their keen sense of smell,polar bears can sense the breathing holes of seals in their dens beneath the snow and ice. As the southern edge of the Arctic ice cap melts in summer, polar bears are stranded on land and spend their summers fasting ,living off body fat stored from hunting in spring and winter. It might come as a surprise that this species faces an uncertain future. Climate change is causing the disappearance of sea ice from which polar bears hunt seals. Sea ice in the Arctic is melting earlier and forming later each year. With about 22,000 polar bears living in the wild,the species is not endangered at the moment, but its future is far from certain. People have reached an agreement that controls the hunting of polar bears and directs each nation to protect their habitats, but it does not protect the bears against the biggest man-made threat to their survival : global warming. If current warming trends continue, scientists believe that polar bears may disappear within 100 years. Question: Polar bears search for seals mainly through their _ . Yes or no, is the answer "noses"?
No

Q: Article: The 9.2magnitude earthquake which caused the tsunami in the Indian Ocean on Boxing Day last year occurred at 7:58 a.m.,95 miles off the west coast of Aceh, Indonesia. Eighteen minutes later.10-metre high waves crashed the ashore along a 500----mile-long stretch of Aceh. Two hours later the tsunami hit Thailand and Malaysia and then Burma, Bangladesh, India,the Maldives,Sri Lanka,Kenya and Somalia.The final death toll is thought to be about 280,000,with tens of thousands more listed as missing.More than l.8 million people lost their homes. *What Is Tsunami? A tsunami is a chain of fast moving waves caused by a sudden strong quake in the ocean.They can be caused by earthquakes,volcanic eruptions ,or even the collision of meteorites .Tsunamis are also incorrectly known as tidal waves,but unlike tidal waves they are not caused by changes in the tides. They are also most common around the edge of the Pacific,where more than half of the world's volcanoes are found.These fast moving waves can attack coastlines,often with little or no warning.Rocks weighing as much as 20 metric tonnes have been pulled from sea walls and carried l 80m inland. *Wave Power Atsunami can have a wavelength in excess of 1 00km and there may be an hour between them.They travel at great speeds across an ocean with hardly any energy losses and are barely noticeable out at sea. Over the deep Pacific Ocean,a tsunami travels at about 800kph.If an earthquake happened in Los Angeles.a tsunami could hit Tokyo quicker than you could fly between the cities by jet. *Strange Animal Behaviors Ten days before giant waves slammed into Sri Lanka and India coastlines,wild and domestic animals seemed to know what was about to happen and fled to safety. Elephants screamed and ran for higher ground. Dogs refused to go outdoors. Zoo animals rushed into their shelters and could not be enticed to come back out. Question: ..Which of the following is a characteristic of a tsunami? Yes or no, is the answer "The waves of a tsunami travel extremely fast."?
A: No
