Article: One day Thomas Alva Edison was given a letter by his teacher. His teacher asked him to give it to his mother. Edison thought it was something nice. After he returned home, he proudly gave it to his mother, saying "My teacher let me give this letter to you." Not knowing what it was, Edison's mother opened it, and then her eyes opened wide. With tears in her eyes, she looked at her son and read out the letter aloud, "Your child is a genius. This school is too small for him and doesn't have enough good teachers to train him. Please teach him yourself." The fact was that Edison liked asking strange questions in class. His teachers thought he was mentally ill. They could no longer stand him and decided to stop him from going to school. However, Edison's mother didn't give up on her son. She taught him at home. Many years after Edison's mother died and he was already one of the greatest inventors, one day he was looking through the old family things. Suddenly he saw a piece of folded paper in the corner of a drawer. He took it and opened it up. It read, "Your son is addled (mentally ill). We won't let him come to school any more." Edison cried for hours and then he wrote in his diary, "Thomas Alva Edison was an addled child, but, by his hero mother, he becomes the genius of the century." Having faith in those we love is very important. We should have faith in those around us. Even if others have given upon you, you should have faith in yourself. Question: What did Edison's mother do after knowing the teachers' decision? Yes or no, is the answer "She let him get educated at home."?

Ques: Article: World top-ranked badminton player Lin Dan said last Friday that he was a better player than Taufik Hidayat in the year of 2006 despite losing the Asian Games single title to the Indonesian Olympic champion. "I have ranked No.1 in the world for two straight years and I think people can easily come to a conclusion on who is a better player for the whole year," said Lin Dan, also known as Super Dan in the badminton world because of his marvelous performance in the sport. Hidayat beat Lin 21-15, 22-20 to give Indonesia its second gold medal in Doha on December 9, retaining his Asian Games singles title and avenging two losses to the badminton world champion. Lin, 23, led China to the men's team title after defeating Hidayat twice in three days, in the preliminary round and in the semifinals of the Asian Games. In their third meeting, Lin came up against a better-prepared Hidayat than he had encountered previously. Hidayat was cheered on by the noisy support from dancing and flag-waving Indonesian fans, who had converted the badminton arena into a national celebration even before the two players stepped onto the court. There's been a lot of acrimony between Hidayat and Lin, who this year won the single title in the world championships after former champion Hidayat crashed out in the quarterfinals. In Doha, Hidayat was quoted as calling Lin "arrogant" before the event began, but the two stars played down the rift (a situation where two people dislike each other). "It's no problem, we're close friends," said Hidayat. "The media _ it." Lin said last Friday in Beijing that he and Hidayat remain friends despite all the rumors . "There is no problem between Taufik and me although we don't talk to each other very much," said Lin. "Media tends to make up things in order to make their stories juicy." Question: What is the relationship between the two players like? Yes or no, is the answer "They both think they are friends."?
Ans: No

Article: A recent report has suggested that air pollution in our big cities could be as damaging to our health. The report put forward practical tips that city people can take to reduce their exposure to city air pollution. Quite a lot, it turns out. * Watch where you walk Avoid walking along busy streets and thoroughfares , instead choosing side streets and parks. because pollution levels can fall by a factor of 10 just by moving a few metres away from the main source of the pollution - exhaust fumes. " Don't walk behind smokers, and walk on the windward, side of the street where exposure to pollutants can be 50% less than on the leewardside. * Pavement sense When you're crossing a road, stand well back from the kerb while you wait for the lights to change. Every metre really does count when you are close to traffic. As the traffic moves, the gases can disappear in just a few seconds, particularly if the wind is up, which means holding your breath during this period can make a difference, silly as that might sound. Besides, cross the road as quickly as possible. And once you're over, continue along the pavement as far away from the kerb as possible. * Where to sit on the bus Sitting on the driver's side of a bus can increase your exposure by 10% compared with sitting on the side nearest to the pavement. And sitting upstairs on a double-decker can reduce your exposure too. It's difficult to say whether travelling on an underground train is better or worse than taking the bus, but the air pollution on underground trains tends to be less toxic by weight than that found at street level. * Wear a mask Masks can be a good thing, but they only make a difference if they fit tightly and are cleaned regularly. Even the slightest gap to allow you to breathe more easily will _ any advantages. Worse, if you fail to clean or change the mask regularly, something dangerous can form on the mask. So the air you breathe is dirtier rather than cleaner. Question: Which of the following is NOT TRUE according to the passage? Yes or no, is the answer "Don't get close to traffic whenever it is possible."?
No
