One expert points out that the percentage of native English speakers is declining while the languages of other rapidly growing regions are being spoken by increasing numbers of people. But English will continue to remain widespread and important. However,British language scholar David Graddol says English will probably drop in dominance by the middle of this century to rank,after Chinese,about equally with Arabic,Hindi,and Urdu. "The number of people speaking English as a first language continues to rise,but it isn't rising nearly as fast as the numbers of many other languages around the world,simply because the main population group has been largely in the less developed countries where languages other than English have been spoken," he says. In a recent article in the journal Science,Mr. Graddol noted that three languages that are not near the top of the list of the most widely spoken now might be there soon. These are Bengali,Tamil,and Malay,spoken in south and southeast Asia. David Crystal,the author of The Cambridge Encycloredia of the English Laeguage, says about 1. 5 billion of the world's six billion people speak it as a second tongue compared to the 400 million native speakers. But another expert on the English language says Mr. Graddol underestimates the future of its dominance. _ but nobody quite knows what's going to happen because no language has been in this position before. " he said. Question: According to David Graddol,which of the folowing will possibly be one of the languages that will be most widely spoken? Options: A: Malay. B: Arabic. C: Urdu. D: German.

Read the article and select the best answer. Article: I once experienced an unforgettable trip to Gloucester to see some of the world's most beautiful and exciting animals in their own habitat , the North Atlantic Ocean. After a long trip by bus, we got on the ship. After a while, we stopped and everyone on the ship started to shout because we saw a humpback whale . It was wonderful. Sometimes, whales came so close to the ship that you thought you could easily touch them. While we were watching the whales, a guide was giving us some information about them. She told us that we saw only two kinds of whales -- 50-foot humpback whales (singing whales) and 70-foot fin back whales (the second largest whales on earth). She also said we could easily recognize a whale by its tail because every whale has a different kind of tail just like people have different fingerprints. They all have names, and on this trip, we saw "Salt" and "Pepper", two whales named by a biologist and a fisherman. They were swimming together all the time. I took twenty-seven photos, but it was very hard to take them because the whales were quick and stayed on the surface of the ocean just for a short time. It was really something. It was one of the chances that a person hardly ever experiences in life, but I had that chance. Question: This passage is mainly about _ . Options: A: an unforgettable experience in the forest B: an unforgettable trip to see some strange animals in the mountains C: a long trip on the ship D: an unforgettable trip to watch whales

Read the article and select the best answer. Article: There are an extremely large number of antsworldwide. Each individual ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior. In colonies that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone , chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit. In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective intelligence greater than you would expect from itsindividual parts. Question: Which of the following contributes most to the survival of ants? Options: A: Their behavior. B: Their size. C: Their number. D: Their weight
