Do you know why different animals or pests have their special color1s? Their color1s in them seem to be used mainly to protect themselves. Some birds like eating locusts , but birds cannot easily catch them. Why? It is because locusts change their color1s together with the change of the color1s of crops . When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color1 as crops have. Some other pests with different color1s from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night. If you study the animal life, you'll find the main use of color1ing is to protect the animals themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters . This is because they have the color1s much like the trees'. Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spreads over , its enemies cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all. How can pests with different color1s from plants keep themselves out of danger? A) They run away quickly. B) They have the color1s much like their enemies'. C) They hide themselves by the day and appear at night. D) They have to move quietly.

London's Chinese community dates back to the 18th century, when a small number of Chinese sailors moved to the city to work in Limehouse, east London. As time went by, other Chinese people came to this area and Limehouse began to be known as "Chinatown". At the start of the 20th century, there were just 545 Chinese people in Britain. However, this situation changed greatly after the Second World War. At this time, many farmers in Hong Kong lost their jobs, and decided to move to London. In the 1950s, a small Chinese restaurant opened in central London. Many British people visited it and said that Chinese food was wonderful! Suddenly, Chinese restaurants started opening in every part of the city. Instead of too little work, the new Chinese immigrants now found that they had too much! Most of the new immigrants enjoyed their lives and the chances they were offered. Many asked their friends and relatives to join them from their hometowns, and a lot of families were reunited again at this time. As time went by, London's Chinese community became more and more successful. The sons and daughters of the first restaurant workers, encouraged by their parents, studied very hard at school and university. And most got highly-paid jobs. As a result, increasing numbers of Chinese families left Chinatown and moved to the more expensive places. Chinatown, however, is still as lively as ever, and a must-see for any visitor to London. The passage is mainly about _ . A) "Chinatown" in World War II B) the history of "Chinatown" in London C) the successful Chinese in London D) an old Chinese restaurant

Ques: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. Noe's making human-like sounds disappeared in _ . A) 1984 B) 2012 C) 2007 D) 1988
