(2)_____, says William Tyznik, an expert in animal nutrition at Ohio State University, ice cream is not good for dogs. "It has milk sugar in it," he says, "which dogs cannot (3)_____ very well."
    (4)_____ by that knowledge but aware of the desire of dog owners to (5)_____ their companions, Tyznik invented a new frozen treat for dogs that, he says, is more nutritious than ice cream—and as much (6)_____ to eat. The product, called Frosty Paws, is made of a liquid byproduct of cheese and milk with the sugar (7)_____. Frosty Paws also contains refined soy flour, water, vegetable oil, vitamins and minerals. It (8)_____ Tyznik, who has also invented a horse food (called Tizwhiz) and (9)_____ dog food (named Tizbits), three years to (10)_____ the Frosty Paws formulas, and two (11)_____ to commercialize it. After losing $25,000 trying to market the invention himself, Tyznik sold the rights to Associated Ice Cream of Westerville, Ohio, which makes the product and (12)_____ it in cups.
    Tyznik claims that Frosty Paws has been tested (13)_____ and that "dogs love it". Of 1,400 dogs that have been (14)_____ the product, he says, 89 percent took it on the first (15)_____. Three out of four (16)_____ it to Milk-Bone or sausages. The product, which will be (17)_____ in the ice cream section of supermarkets, comes in (18)_____ of three or four cups, costing about $1.79.
    What would happen (19)_____ a human should mistake Frosty Paws for real ice cream? Nothing, says Tyznik. It’s (20)_____, but frankly, he says, it won’t taste very good.

选项 A、harmful
B、harmless
C、effective
D、ineffective
答案B
解析 本题的考点为对上文内容的理解和形容词的词义辨析。通过上句中的 Nothing一词可知，人吃了它什么事也没有，所以应该是无害的。因此，harmless"无害的"符合文意。harmful"有害的"，effective"有效的"，ineffective"无效的"都与文意不符。
