B.羊毛脂可作为软膏剂油脂性基质
C.聚乙二醇为油脂性基质
D.性质稳定，与主药不发生配伍变化
E.不妨碍皮肤的正常功能，具有良好释药性能
参考答案：C
解析：软膏剂基质要求：润滑无刺激，稠度适宜，宜于涂布；性质稳定，与主药不发生配伍变化；具有吸水性，能吸收伤口分泌物；不妨碍皮肤的正常功能，具有良好释药性能；易洗除，不污染衣物。聚乙二醇为水溶性基质，C选项说法错误。所以答案为C。
The teacher stood before his class and was going to hand out the final exam papers. “I know how 1 you have worked to prepare for this test,” he said. “And because I know you can do it well, I am willing to offer a B to those who 2 not to take the test.” Many students thanked the teacher and left. The teacher looked at the students left and said, “Does anyone else want to get a ‘B’? This is your last 3 .” Two more students decided to go. Only seven students were still in the classroom. The teacher then handed out the papers. There were only three sentences on the paper: Congratulations! You have just 4 an ‘A’ in this class. Keep believing in 5 . I never had a teacher like that, but I think it is a test that any teacher could give. Students who are not 6 in what they have learned are ‘B’ students at most. The same is 7 in our daily life. The ‘A’ students are those who believe in what they are doing because they have 8 both successes and failures. They have got life’s lessons, not only from normal education, but from events in their 9 , and have become 10 people. You see, one should always believe in himself.
