I'm taking a test and have to guess the right answer to the question after the article. Article: Internet reports of whales sounding like people are not new. But in this case in San Diego, California, scientists for the first time recorded the utterances, did an acoustic analysis and were surprised to find a rhythm similar to that of human speech, Sam Ridgway of the National Marine Mammal Foundation reported on Monday. The sounds marking is quite special : Whales make sounds through the system of the nose, unlike people, who use their throat. So this particular with whale had to make some tricky muscular and blowhole adjustments. "Such obvious effort suggests motivation for relatin", said Ridway, the main author of a study featured in the journal Current Biology. "The sounds we heard were clearly an example of vocal learning by the white whale." The wale, named Noc, died five years ago. Ridgway says that back in 1984, he and others started hearing sounds near the whale and dolphin enclosure that recalled two people speaking in the distance, too far away to be understood. The sounds were later traced to one particular white whale when a diver in its tank came to the surface because he thought he heard colleagues tell him to do so. Noc had lived among dolphins and other white whales and had often been in the presence of humans. The whale made human-like sounds for around four years until it reached the age of sexual maturity, Ridgway said. Question: Noe's making human-like sounds disappeared in _ . Options: A: 1984 B: 2012 C: 2007 D: 1988

I'm taking a test and have to guess the right answer to the question after the article. Article: A man called Greedy Black loved nothing but old things. He was so crazy about everything that was old and out of fashion because he was convinced that the older, the better. Always worried about losing his treasures, he kept all he had collected in an old room. It had no windows, so it was very dark, and of course, it was full of old things. One day Greedy Black went into this room to get a ladder, as he had often practiced, but slipped on something and fell against a big garden fork. The fork hit him on the head and knocked him down. Then it fell on top of him and hit him hard on the left leg. The ends of the fork then went into his long beard. He fought with the fork fiercely, and at last threw it off him, jumped up and ran out of the room. He was very angry. He had an old sword under his bed, and he now ran and got this. Then he ran back to the room, opened the door suddenly and shouted in a terrible voice, "All right, come out and fight, you and all the other forks in the world! I'm not afraid of you!" But there was no response for his challenge. So in great _ , he turned on the electric light, only to find that there was no other fork but the one that had repeatedly troubled him. After reading this story, what reflections have you got for yourself? Do you still think that keeping old things in a private place sounds sound? Or don't you believe that you have to be far away from forks because forks are the most powerful? Or what else.....? Question: Which of the following is true according to the story? Options: A: The man believed that he could win the game. B: The man became mad after he was in the room. C: The man mistook one fork for more than one. D: The man was wondering how to kill thieves.

I'm taking a test and have to guess the right answer to the question after the article. Article: The ecosystem is 1ike a chain.If any of the links are broken,the whole system is in danger.This is why wetland protection has been put high on the agenda in recent years.Zhao,vice--director of the State Forestry Administration,says nearly 60 percent of the country's natural wetlands are still not under effective protection.Most Chinese people are ignorant about the importance of protecting the wetlands. Ocean,forestry and wetlands are the three global ecological systems.Wetlands can conserve and purify water resources, prevent flooding and help protect the ecosystem. As well as ecological values, they can also offer economical returns. In recent years,many wetlands have become farmland.Drawing too much underground water,hunting and fishing also ruin their ecological system. Every year,the wetlands in the Sanjiang Plain of Northeast China provide habitat for birds.Local residents search the area for the birds' eggs. They consider the eggs to be a natural gift. rather than wildlife that should be protected. If they were educated,perhaps this is one activity that could be brought to an end. China is now ready to make a plan to save some of these areas.Some have been restored to raise awareness among the public.But these moves are not enough.There should be laws in place to provide legal support to the fight. Environment protection is a campaign which needs support from everyone in society.Education may be the first step. Question: What is the best title of this passage? Options: A: Ocean, forestry and wetlands are the three global ecological systems. B: Environment protection is a campaign. C: Wetland protection keeps ecological harmony. D: The ecosystem is a chain.
