完形填空
Last week, I took a sales class for female business owners. The     36   thing the instructor did was ask if anyone had been the victim of a     37   sales experience. Every person in the room    38   her hand.
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. I bought a summer membership at our community pool     43   because it advertised a lovely baby pool to which I could escape with my active one and four year-olds. 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. When the baby pool was closed, I had to swim with my     48   in the adult pool, which did not     49   me the control I wanted and as such, was quite stressful. I would have rather stayed home.
The pool has     50  a customer. I will not be buying a pass next summer.
In work and in life, it is really important not to     51   something you can’t deliver, because at best, it will improve your   52    . At worse, you could lose your job.    53   , before you assure a co-worker or customer that you can get something done, make sure that your boss or someone higher-up isn’t going to step in and force you to     54   your plan. You are not God, so don’t lead people to believe that you     55  the universe.
