My best friend and I were in the shop that she owns. It was the middle of the afternoon. We were both very happy and making plans for the weekend. Suddenly a man entered the shop. We knew that he didn’t look like one of our usual customers, but we welcomed him _ __ anyway. Without any hesitation he pulled something out of his coat. We didn’t notice that it was a __ __ until he ordered us to go into the back with him. After he warned us that he could fire at any time, he looked for the money everywhere, in the bank, from our wallets, and then he asked for our jewellery (珠宝) and we gave him all he wanted. Finally, he finished his “job” and left. When I was a child, I felt safe with my parents in my home or wherever I was not alone. Then I began to understand the news and I learnt that __ __ things were happening “out there”, but I still kept thinking that those events were just other people’s __ __, not mine. From the moment the man walked out of the shop, I completely ___ ___. I always look around to see which kinds of people are possibly following me. Now I usually double-check everything: if I’ve locked myself in the car or in the house. I am always careful not to wear any jewellery. Whenever a stranger is getting too close or is trying to get information from me, I feel nervous. I know that it is wrong, and that not everyone is going to _ __ me again. After all, I consider myself lucky, since nothing really bad happened to me or my friend, but since that day I haven’t felt safe any more. I hate that man not for having taken my jewellery and money, but for having deprived（剥夺）of my innocence.
