答案與解析：
46.A。文章第一段提到，我們都曾感覺(jué)過(guò)疼痛。從空格前一句的內(nèi)容，即“有些人很少遭受疼痛之苦”，可以推斷空格處句子的內(nèi)容應(yīng)當(dāng)與這一句的內(nèi)容相反，即“另外一些人卻總是遭受疼痛的襲擊”。
47.C。空格前的句子講到，疼痛是我們身體的警報(bào)系統(tǒng)。因此接下來(lái)的句子應(yīng)該說(shuō)明這樣說(shuō)的原因。
48.D。空格后一句講到，然而，有關(guān)疼痛過(guò)程的新知識(shí)使醫(yī)生得以更好地控制疼痛。由此可見(jiàn)，空格處句子的內(nèi)容應(yīng)與此句內(nèi)容相反，即醫(yī)生對(duì)疼痛過(guò)程了解得很少。
49.B。空格前一句中的“chemical and electrical signals”等詞語(yǔ)是對(duì)空格處句子的很好提示。
50.E。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“Thefirstmessage”，顯然，空格處的句子應(yīng)以“Theothermessage”開(kāi)始。
