    　　Thirty years ago, when the movie version of my novel Jaw was published, few people including me knew very much about great white sharks．For hundreds of generations, we humans have been taught to fear and hate sharks, and the movie touched a nerve of horror．

    　　Now something long thought impossible has happened．A great white shark was successfully held in capacity for several months．In August last year a very young female great white shark was caught accidentally in a fisherman’s net off Huntington Beach, California, and then kept in an ocean pen(栏栅)for 25 days．After being moved to the Monterey Bay Aquarium (水族馆), she grew well in the million-gallon Outer Bay Exhibit．She was so lovely that people all liked her very much．Perhaps she was too young to understand that the big tank was not her natural environment, because she didn’t hit her head against the walls in an attempt to swim away as others of her kind have done．And she began to feed almost immediately on small fish offered to her on a pole．In the months that followed, the shark suffered no serious injuries, caught no diseases, and grew noticeably larger, breaking all records for great white sharks in capacity．The longest that any other great white shark had been held was 16 days．

    　　Until February 23, that is, when she hit and killed a soup fin shark(翅鲨), as she grew bigger and her behavior grew more aggressive, officials at the Aquarium knew the time had come．On March 31, after 198 days in the aquarium, the great white shark was released into the Pacific．

    　　Scientists still have a lot to learn about sharks, especially great white sharks which are now considered to be in danger．Scientists do know that sharks are necessary to ocean health．Remove any significant animal from the sea food chain and you will risk destroying the balance of nature．

    (1)

    We can see that in the film Jaw the shark was once described as ________．

    [　　]

    A．

    C．

    loyal and friendly

    D．

    By saying that“officials at the aquarium knew the time had come”, the writer probably means that the female great white shark ________．

    [　　]

    A．

    had to be killed

    B．

    escaped from the big tank

    C．

    had to be set free

    　　Up until now, Disney's attempt into China has been anything but magical．Its Hong Kong theme park, opened in 2005, has had a difficult time due to early mistakes and competition．But Disney doesn't throw in the towel in a market with 1.3 billion potential customers．After more than a decade of negotiations, Disney can build its second Disneyland in Shanghai．

    　　Disney officials wouldn't say when the park will open or how much it will cost．But the company stated in press release that the Shanghai park will include“characteristics adapted to the Shanghai region”．

    　　The approval for park construction comes among China's ongoing efforts to develop its tourism sector, which is expected to increase by 3％ this year．

    　　Since the mainland Chinese make up a third of visitors to Hong Kong Disneyland, some fear that the Shanghai park will take tourists away from the former park．Since opening four years ago, Hong Kong Disneyland has underperformed due to its small size－300 acres, the smallest of any Disney parks－as well as high ticket prices and competition from Ocean Park．

    　　Disney has also made several market miscalculations．Analysts say the company, in trying not to make the same mistakes it did in Paris by failing to be adapted to local tastes, may have done too much in its efforts to adapt the Hong Kong park to Chinese customers．For example, the park's restaurants originally planned to serve the shark's fin soup, until environmentalists protested(抗议)．

    　　Disney officials dismissed concerns that a new park in Shanghai will steal Hong Kong customers．“We see Hong Kong Disneyland and the Shanghai park as complementary(互补的),”said an official．“We believe the Chinese market is large enough to support more than one park．”

    　　Further expansion in Asia may be a good bet．Last year, roughly a quarter of Disney's profit came from overseas operations．Asia contributed just 5％, but leisure-industry experts are confident about the region's potential．

    (1)

    The underlined phrase“throw in the towel”in Paragraph 1 means“________”．

    C．

    bring hope

    D．

    invest more money

    C．

    hosting a successful Disney celebration

    D．

    promoting the development of local culture

    (3)

    A tourist gives up the idea of visiting Hong Kong Disneyland probably because ________．

    [　　]

    A．

    it is not well adapted to Chinese customers

    B．

    it lacks attractions

    C．

    environmentalists protest

    D．

    it is very small and the ticket price is high

    (4)

    [　　]

    A．

    only after long years of negotiations can Disney build its second park in Shanghai

    B．

    when the Shanghai park will open and how much it will cost haven't been decided

    C．

    the Shanghai park will be as successful as the Hong Kong theme park

    D．

    Humpback whales

    　　A humpback whale breathes air at the surface of the water through two blowholes which are located near the top of the head．It blows a double stream of water that can rise up to 4 meters above the water．

    　　The humpback has a small dorsal fin located towards the tail flukes about two-thirds of the way down its back other distinguishing features include large pectoral fins, which may be up to a third of the body length, and unique black and white spots on the underside of the tail flukes．

    阅读下面短文，根据所读内容在文后第1至第10小题的空格里填上适当的单词或短语。

    注意：每空不超过3个单词。

    　　Sharks have lived in the oceans for over 450 million years, long before dinosaurs appears．There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely．

    　　Sharks range in size from the 6-inch-long dwarf-dog shark to the 60-foot-long whale shark－the world’s biggest fish．The whale sharks, like two other large shark species－the basking shark and the mega mouth shark－are harmless to people because they feed on plants and small aquatic animals．

    　　Every year, we catch and kill over 100 million sharks, mostly for food and for their fins．Dried shark fins are used to make shark fin soup, which sells for as much as $50 a bowl in fine Hong Kong restaurants．Other sharks are killed for sport and out of fear．Sharks are vulnerable(脆弱的) to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring．

    　　While sharks are seen as people-eating monsters, they help save human lives．In addition to providing people with food, they are helping us in cancer．They are among the few animals in the world that almost never get cancer．A research shows that chemicals extracted from shark cartilage(软骨) have killed cancerous tumors in laboratory animals．Their highly effective immune system also allows wounds to heal quickly without becoming infected．

    　　Sharks are needed in the world’s ocean ecosystems．Although they don’t need us, we need them．We are much more dangerous to sharks than they are to us．For every shark that bites a person, we kill one million sharks．

    To support the recent Earth Day, a small group of HELP University College students from the

    Greens Club, a nature society, did their bit for the hard situation of an unlikely mistreated group: sharks (鲨鱼).　

    Nearly 100 million sharks are killed every year for their fins (鳍)，which are made into shark fin soup that is referred to as the delicacy.

    Some members of the club spent one month gathering research materials for a show. “I thought I already knew how sharks were treated—I never thought it could be so cruel,” admitted Hui zhi, who helped set up the “shark murder” TV corner for the club and was one of the first to watch the video materials. “It’s very beneficial to anyone who watches it”, said Clarence meanwhile. “And watching it probably does a lot to get people to stop eating shark fin soup and stop the demand for it.” He is right. Watching the poor sharks killed at the hands of human is not different from watching one’s beloved household pet killed unmercifully(无情地) just for something God gives them, like fins, or fur.

    “Young people can influence their parents’ thinking. We wanted to screen Shark Tale to show the human side of sharks, the human side that every animal has.” added Ee Ling, who founded the Greens Club three years ago.

    Fortunately, there is the good sense of young hearts and minds like Ee Ling and friends who are able to see and value the soul in natural things before they become exploited (不正当地利用) for our own pleasure.　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　

    1. Why are so many sharks killed every year?

    　 A. People hunted them for their fins.　　　　　　

    B. Because they are dangerous to fishermen.

    　 C. Because people want to screen “Shark Tale”.

    　 D. Because they are not like our beloved pets.

    2. Form the passage we can infer that______.

    　 A. shark fin soup is the best delicacy in the world

    　 B. people who watched the video materials about sharks would stop eating shark soup at once

    　 C. people don’t like sharks

    　 D. many people aren’t able to see and value the soul in natural things

    3. How does the writer feel about the present situation?

    　 A. depressed　　 B. angry　　　　 C. sad but hopeful　　　 D. disappointed
