不符合呼吸系统疾病引起的咳嗽、咳痰特征的是（）
A.长期、频繁的咳嗽可使胸腔内压增高
B.剧烈的咳嗽常可引起呼吸肌疼痛
C.常分为干性咳嗽和湿性咳嗽

参考答案：D
解析：咳嗽是一种保护性反射动作，通过咳嗽可以清除呼吸道分泌物和进入呼吸道内的异物。咳嗽也有一定的危害性，例如长期、频繁的咳嗽可使胸腔内压增高，影响静脉血回流，每一次咳嗽动作都对肺泡产生一次压力性冲击作用，剧烈的咳嗽常可引起呼吸肌疼痛。咳嗽是呼吸系统疾病常见的症状之一，咳嗽无痰或痰量甚少，称为干性咳嗽。

Susan suddenly felt sad. She knew this man would take all that he could get. So she went up to him and gave him some fruit. The man looked up in 5 and took what she gave him. A big smile appeared on his face and she felt very happy. Then he said, "Wow! First someone gave me this sandwich, then the orange juice, and now some delicious 6 . This is my daughter's lucky day. Thank you, girl." Then he went 7 , singing a song. Just then, Susan understood 8 the saying "Giving is getting" really meant.
