1.参考答案:D
参考解析:空格后一句讲到,然而,有关疼痛过程的新知识使医生得以更好地控制疼痛。由此可见,空格处句子的内容应与此句内容相反,即医生对疼痛过程了解得很少。?
2.参考答案:E
参考解析:文章第四段最后一句提到了“two different kinds ofpain messages”,而文章最后一段第一句中又用了“The first message”,显然,空格处的句子应以“The other message”开始。3.[不定向选择题]第47题___________A.And others have painful attacks all the tim B.These signals travel from nerve cells in the injured area, up the spinal cord ( 脊髓 ) to the brain, and back down agai C.It tells us that we are injured and should do something about i D.They knew little about the process of pain itselE.The other message moves at a speed of only one meter a second,F.And they send the second, slower message of pain tot.he braiABCDEF确定
