(5) A new species of snake has been discovered on a remote island in the Bahamas. Scientists identified 20 of the one meter-long snakes during two trips to the Caribbean islands. The second trip was made in October last year.
    (6) One of the creatures made a dramatic appearance by moving on to the head of the team leader as he slept.
    (7) The snake has been named silver boa because it is metal colored and the first specimen found was climbing a silver palm tree.
    The team was led by Dr. Graham Reynolds, from Harvard University. The scientist confirmed the snake was a previously unknown species after conducting a genetic analysis of tissue samples.
    Commenting on the find, snake expert Robert Henderson from the Muworki Museum of Natural History said: "Worldwide new species of frogs are being discovered and described quite regularly. New species of snakes, however, are much rarer."
Questions 5 to 7 are based on the news report you have just heard.
5. What is the news report mainly about?
6. What do we learn about the scientific team leader?
7. How did the newly discovered creature get its name?

选项 A、From its genes.
B、From its length.
C、From its origin.
D、From its colour.

答案 D

解析 浏览四个选项,从选项中的from可推测,此题与某物的来源有关。题干问的是新发现的生物其名字是如何得来的。新闻中提到,这条蛇被命名为银色蟒蛇是因为它是金属色,并且第一条被发现时它正在攀爬一棵银色棕榈树,D项与原文提供的信息一致,故答案为D。A项(来自它的基因),新闻中提到“通过进行组织标本的基因分析,科学家们确定了这条蛇是先前未发现的物种”,因此基因不是其名字的来源,故排除。B项(来自它的长度),C项(来自它的出身)文中均未提及,故排除。
