There were only a few coins in the hat. A man was walking by. He took a few coins from his pocket and dropped them into the hat. He then took the sign, turned it around, and wrote some words. He put the sign back so that everyone who walked by would see the new words. Soon the hat began to fill up. A lot more people were giving money to the blind boy. That afternoon the man who had changed the sign came to see how things were. The boy recognized his footsteps and asked :"Were you the one who changed my sign this morning? What did you write?" The man said: "I only wrote the truth. I said what you said but in a different way." What he had written was: "Today is a beautiful day but I cannot see it." Do you think the first sign and the second sign were saying the same thing? Of course both signs told people the boy was blind. But the first sign simply told people to help by putting some money in the hat. The second sign told people that they were able to enjoy the day, but the boy could not enjoy it because he was blind. The first sign simply said the boy was blind. The second sign told people they were so lucky that they were not blind. There are at least two lessons we can learn from this simple story. The first is: Be thankful for what you have. Someone else has less. Help where you can. The second is:Be creative. Think differently. There is always a better way! Question: The blind boy recognized the kind man by his _ . Options: A: words B: smell C: voice D: Footsteps

A giant spider web was recently found there. The thick web is swarming with millions of little spiders. Stretching across several acres it blankets a number of trees, bushes and even the ground. While the web may make some people nervous, it has become a big attraction for others-especially for unlucky insects. "At first, it was so white that it looked like fairyland," said Donna Garde, the park's manager. "Now it's filled with so many mosquitoes that it's turned a little brown." Most spiders work alone, which is why the discovery of the huge web has caused such a stir. Scientists across the country have been debating its origin. Some spider experts' say the monstrous web may have been weaved by social spiders. Social spiders work together to build larger webs to catch small insects. However, those webs take years to build. Park officials say this web was formed in just a few months. Others say it could be the work of millions of tiny ballooning spiders. These types of spiders 'fly' by throwing out thin threads of silk, which they use to ride air currents . In 2002, a similar giant web made by ballooning spiders was discovered in a field in Canada. Texas entomologist Herbert Pase says the giant web is very unusual. "From what I'm hearing, it could be a once-in-a-life-time event," he said. But John Jackman, an entomologist and professor at Texas A&M University, disagrees. Jackman says he hears reports of similar webs, like the one in Canada, every few years. "There are a lot of folks that don't realize spiders do that," he said. "Until we get some samples sent to us, we won't know what species of spider we're talking about." Park officials expect the web to last until fall when the weather gets cooler. That's when the spiders begin dying off in the park. Question: What is the main reason for scientists' excitement and argument about the giant web? Options: A: Most spiders work alone, which makes it hard to understand how the web formed. B: The huge web causes too many mosquitoes to be killed, which is unbelievable. C: No similar discoveries have ever been made throughout the world so far. D: The web forces people to stay far away from Lake Tawakoni State Park.

Article: Close relationships, thought to help communication by giving speakers a common context, are actually more likely to make _ when strangers are involved, a new study suggests. Because close colleagues and friends already share so much common knowledge that they often use short, ambiguous messages which can lead to misunderstandings. "People are so used to talking with those with whom they already share a great deal of information that, when they have something really new to share, they often present it in a way that they assume the person already knows it." says study-team member Boaz Keysar. Keysar and his graduate student, Shall Wu, trained 40 pairs of undergraduate students to memorize made-up names and descriptions of strange shapes. In each pair, the "director" had to communicate the identity of one of the 24 shapes. The partner had to use the information to choose the correct shape from a set of three images on a computer monitor. Half of the partners studied only the first six shapes, while the others learned the first 18 shapes. The directors, who had memorized all the shapes, were aware of their partners' knowledge levels of the shapes. In the pairs with the most shared knowledge, the directors were more likely to rattle off shape names, compared with pairs with little knowledge overlap , in which the directors were more likely to describe the actual shapes. Not surprisingly, participants with more shared knowledge were twice as likely to ask for clarification as those with less overlap. Language itself can be confusing. "The reason all this is happening at all is that language in general is ambiguous," said Keysar. He recalls an ambiguous billboard near a stadium holding a Rolling Stones concert that night. The billboard read, "Avoid LSD tonight." (:LSD"") Hmmm? "It was about Lake Shore Drive, and I'm sure the writer of the sign didn't realize he was being ambiguous," Keysar said. "Even though miscommunication can lead to missed meetings or deadlines, people are often unaware when their language is... Question: By this passage, the author mainly wants to say _ . Options: A: ambiguous language can lead to misunderstandings B: familiarity can mess up communication C: accurate descriptions of identity help guess shapes D: close relationships do not mean good communication
