When she knew details, we learned that the 39 situations had one thing in common. It 40 that whenever a class member had a bad sales experience, it involved the 41 promising something he wouldn’t or couldn’t deliver. The example I 42 with the class was a current one.

However, every time I’ve used the pool this summer, the baby area has been 44 . Too much chlorine(氯气), 45 one manager. I’m sure the pool director was very apologetic that his 46 had been inconvenienced, and that’s nice, but the 47 is that I did not get what I paid for.

You are not God, so don’t lead people to believe that you 55 the universe.
