A.哌拉西林

B.苯唑西林

C.氟氯西林

D.头孢哌酮

E.氨曲南

答案

参考答案:A

解析:不能正确选择的原因是记忆混淆。①苯唑西林和氟氯西林是耐酶的半合成青霉素类。头孢哌酮是三代头孢菌素类对酶稳定,氨曲南属单环β-内酰胺类抗生素,对革兰阴性菌有强大的抗菌作用,对革兰阳性菌弱,具耐酶、低毒等特点,这样BCDE均排除。

A woman repeated a bit of gossip (流言) about a neighbor. Within a few days the whole neighborhood knew the story. The neighbor was deeply hurt. Later the woman learned that it was completely untrue. She was very sorry and went to a wise old man to find out what she could do to repair the harm.

“Go to the market,” he said, “and buy a chicken, and have it killed, then on your way home, pick its feathers(毛) and drop them one by one along the road.” Although surprised by this advice, the woman did what she was told.

The next day the wise man said, “Now, go and collect all those feathers you dropped yesterday and bring them back to me.”

The woman followed the same road, but she was so discouraged when she found the wind had blown all the feathers away. After looking for hours, she returned with only three in her hand.

“You see,” said the old man, “it’s easy to drop them, but it’s impossible to get them back. So it is with gossip. It doesn’t take much to spread(散布) a gossip, but once you do, you can never completely undo(弥补) the wrong.”
