Article: Experts believe that storms and severe weather in North America and Asia have disrupted bird flight paths across the world and swept huge numbers of bird species towards the British Isles. Birds flying to the other side of the Atlantic or to the Pacific to lay their eggs have been trapped in Britain and Ireland, adding their numbers to native species, and causing great excitement in the bird-watching community. Local birdwatchers have already observed a total of 442 species in the British Isles this year. The highest number ever seen in one year is 445, in 2008. "We only need four more to break our record," said Lee Evans, who runs the British Birding Association. "With three months to go I'm sure we'll do it." Last month an extremely rare Siberian Rubythroat bird was seen in Scotland, sending hundreds of birdwatchers north in the hope of catching a glimpse of this colourful Asian beauty. Another very uncommon bird, the bufflehead duck was cited in Cornwell and caused similar excitement. "I couldn't believe it," said Evans. "The poor thing was completely _ . It must have been blown to England by the storms while trying to fly from Canada to the southern United States for the winter. That's 3000 miles!" Evans said that global warming over the past decade was playing a key role in transforming bird movements across the world. In addition, melting Arctic sea ice may also be opening up bird flight paths over the North Pole, making it easier for birds from the Pacific -- such as the slaty-backed gull and tufted puffin, both of which appeared in London earlier this year -- to reach Britain. Bird-watching is becoming an increasingly popular hobby among all age groups, added Evans. "A fifth of our members are under 18. This is a round-the-year hobby that you can enjoy from the kitchen window or from a car. More and more people are bird-watching, and as a result more and more unexpected species are being spotted in the British Isles."
Question: What is the passage mainly about?

Article: One day, a brave jackal came to the river to drink some water. He saw a lion looking weak and tired, and asked, "What is the matter, King of the Jungle?" The lion told the jackal his story. The jackal felt sorry for the lion. He pulled and pulled at the lion's tail until the lion became free. The lion was very happy and said, "Thank you so much for helping me. I thought I would die! You are my friend for life! I would like you to come and live with me. From now on, I will hunt and share my food with you." The jackal moved in with the lion's family and had a wonderful time. Soon, the lion had children of his own and so did the jackal. The lioness was not happy about the friendship. She complained to her children. Her children complained to the jackal's children; the jackal's children complained to their mother and their mother complained to the jackal. The jackal was upset and told the lion, "You told me to live with you. If you don't like it any more, you should have said so yourself." The lion was shocked and said, "This is not true. I've never complained about you. I still want you to continue staying with me." The jackal said, "We understand each other. But our families don't. Perhaps it is better for us to live apart, but continue meeting each other when we are free. We can even hunt together!" The two families parted, but the lion and the jackal met often and remained friends for the rest of their lives. From the above paragraphs, we can conclude that in order to keep our good friendship, we have to give something up or give in in some particular cases. However, we can never give up or destroy our families. What do you think of it?
Question: How was the lion when the jackal first met him?
Options: (A) Strong and happy. (B) Fierce and cruel. (C) Kind and friendly. (D) Weak and tired.
answer:
D

question:
Article: Today is Sarah's birthday. She is seventy-five. We asked a few old friends to dinner. Like most elderly people, I suppose, we spent most of the evening talking about old times. Thirty years ago, the village used to be a quiet place. Now it has changed. Every Sunday hundreds of cars pass through the village at what I think a dangerous speed. They make the village almost as noisy as the streets of a large town. As a boy I enjoyed riding on the backs of the farm horses. Things are different now. Today there are very few horses working on the farms. The farm workers today drive tractors, not horses. A man is not of much use on a farm unless he knows all about machines. Now almost every house in the village has a TV set. Is it a good thing for children to spend the evening sitting in front of a TV set? When I was young I did not waste my time indoors. I would spend the long summer evenings outdoors. I would play with my friends, go fishing or walk by the river. When my grandchildren asked me the reason why I haven't bought a TV set, I tell them there are many books I still want to read. I can't find time for both reading and watching TV.
Question: The old like to talk about _ .
Options: (A) themselves (B) others (C) the past (D) nothing

C
