问题    Turkeys (the birds) are originally from the Americas. The Europeans knew a similar looking and tasting bird, known nowadays as Guinea fowl, originally from Africa but introduced through the Ottoman Empire, who was called the turkey-cock or turkey-hen. When the Europeans arrived to the Americas and found the bird we now know as turkey, they called it turkey by association.
   Ben Franklin preferred them to bald eagles. While Ben Franklin never actually endorsed them for the position of national bird (as some believe) , he did praise them as being " a much more respectable bird" in general than the bird of prey bald eagle. He also added, " He is besides, though a little vain & silly, a Bird of Courage, and would not hesitate to attack a Grenadier of the British Guards who should presume to invade his Farm Yard with a red Coat on.
   Wild turkeys feed on the ground, which may have something to do with the myth that they can’t fly. They have to fly, however, because they roost in trees at night. Some accounts say they can soar up to 55 mph for short bursts.
   A gobbler’s droppings usually take the shape of a "J" or sometimes a question mark. A hen leaves droppings that more closely resemble a spiral that is all in one pile.
   Americans particularly love to eat turkey breast meat, so turkeys have been selectively bred over the years to have bigger and bigger breasts. Artificial insemination is a required part of turkey breeding as the modern bird is too heavy and misshapen with its massive breast area to procreate the old-fashioned way.
   Turkeys’ heads actually change colors from red to pink, white, blue, or gray depending on its mood. So you could say that they blush!
   Turkeys have a 270-degree field of vision (360 when they rotate their heads) , can see in color, and see three times more clearly than 20/20.
   Turkeys climb up into trees when it’s time to go to sleep, and throughout the night they keep watch over one another to make sure no predators are lurking. In the morning, they gobble softly to each other as a form of headcount to make sure everyone made it through the night.
   Turkeys do a lot more than gobble. Their loudest sounds can be heard from more than a mile away. Each turkey sounds slightly different than the next; this is how they tell each other apart.
   Turkeys can form a visual map of their territory, remembering tiny details of an area exceeding 1,000 a-cres even after more than a year apart.
   The heaviest turkey ever recorded reportedly clocked in at a whopping 86 pounds. Nearly 50 million turkeys are expected to be eaten on Thanksgiving this year.
Which of the following statements is true?

选项 A、Both wild and raised turkeys can fly.
B、Turkeys can literally blush when embarrassed.
C、Turkeys, like many animals, are colorblind.
D、Turkeys gobble to distinguish from each other.

答案D

解析 事实细节题。倒数第三段提到,每个火鸡的声音都与其他火鸡略有不同,它们以此来区分彼此,故[D]项为答案。第三段提到野火鸡会飞,但第五段提到饲养的火鸡胸部畸形发达,由此推断,饲养火鸡无法飞,故排除[A]项。第六段提到,火鸡的头部会根据其心情改变颜色,但未提到火鸡会因为尴尬而脸红, [B]项属于过度引申。第七段提到火鸡可以看清颜色,故排除[C]项。
