Scientists in Brazil have used frog skin to
A.eliminate bacteria.
B.treat burns.
C.speed up recovery.
D.reduce treatment cost.

参考答案B
解析:细节理解题。听力材料中一上来便提到巴西的科学家宣布找到了“treat burns”的方法,“Scientists in Brazil claim they’ve come up with a new way of treating burns.That is,with frog skin.”[A]、[C]、[D]材料中也有所提及,而且也是青蛙皮肤的作用,但都是具体的功效,而不是使用青蛙皮肤的目的。故本题答案为[B]。



巴西研究者利用青蛙皮覆盖严重烧伤患者的创面,取得了良好的辅助治疗效果。研究者称青蛙皮含有丰富的天然抗感染、消炎和抗过敏成分,用青蛙皮覆盖烧伤创面可使结痂的时间缩短一半。此方法已经在巴西一些医院进行临床应用。
