第一节：阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。

The other day, I bought six packages of ink for my printer, then I found a deal on better ink at the local computer store, so I went back to the $1 Store to exchange the ink for some other items.

I put the ink into a plastic bag and tied it up. When at the store, I immediately showed the bag to a clerk and told her that I was returning some items, but she was obviously very busy. Then without thinking much, I just put the bag into a cart and started shopping.

I was making my way through the crowd when a female employee suddenly yelled to stop me. I was told not to be allowed to carry a plastic bag of items around in the store and my bag should be checked.

I was astonished. There was no need for her to yell. I opened the bag and showed her the receipt. “I’m returning these to exchange for some other items,” I said.

“You should learn how to follow store regulations. Leave this bag here with the clerk. You can have it back when you check out”.

I was embarrassed and did as told to. I felt like a shoplifter. By the time I had finished shopping and exchanged the items, I was angry and then went looking for her. I wanted an apology. I found her finally and asked what her name was. She yelled at me again, “Ursula!” and stormed away.

Having got home, I called the store’s headquarters. I described my unpleasant experience. A customer service representative responded, “We will not tolerate such behavior. Give me your phone number and I will call you back.”

Two days later, I received a phone call from the representative, “I’m sorry,” she said, “but there is no one at that store named Ursula. Can you describe her? I’ll find out who she is. We do not tolerate rude behavior, nor do we tolerate lying to customers.”

By this time, I had calmed down, so I told the representative to forget about it.
