In contrast to true hibernators such as woodchucks and hedgehogs, whose body temperatures drop close to the freezing point during the winter months, the body temperature of bears remains nearly normal throughout their prolonged sleep. (A) the body temperature of bears remains nearly normal (B) a nearly normal body temperature is maintained by bears (C) a bear’s body temperature remains nearly normal (D) a bear maintains a body temperature that is nearly normal (E) bears maintain a nearly normal body temperature 为了和hibernators平行,必须选择bears,但是我的疑问是为什么后面是“a temperature”而不用复数。。。。。不统一了阿 求nn帮助 |
