问题 Which of the following best states the main idea of the passage?
Which of the following statements is true7
选项 A、Developing fever is the privilege of warm-blooded animals, so sick lizards can not run a fever.
B、Invertebrates also have the ability to raise their temperature.
C、The internal temperatures of warm-blooded creatures are independent of the weather, so are the cold-blooded animal.
D、Sick lizards move into the sun to develop fever.
答案B
解析 本题测试的是文章的细节部分。文章第一段开始两句话告诉我们升高体温曾被认为是热血动物的特权，但是冷血动物也同样具有这种能力，蜥蜴就是一个例子，因此A项不正确。文章第二段Now,fever has spread to invertebrates.(现在，升高体温的能力扩展到了无脊椎动物。)由此可见B项“无脊椎动物也具有升高体温的能力”是正确答案，C项中所说热血动物的体内温度是独立于天气之外的，这是正确的说法，但冷血动物是否也如此，文章并未提及，故放弃。生病的蜥蜴是呆在笼子里以求体温升高，所以D项也不正确。
