I can still remember the first Halloween holiday I had in the USA.On the morning of Halloween, we paid a visit to a pumpkin farm. Each of us brought a pumpkin to school with us. I used the pumpkin to make a lantern which had two triangle eyes and a scary mouth.In the afternoon, we put on the Halloween costumes and went on parade in school. Some of the costumes were nice, but some of them looked scary. I chose to wear a suit of Superman’s clothes.I did a lot of things that day, but the part I liked best was “trick or treat” in the evening. After dinner, I went outside with an empty bag. I hoped to get a lot of candies from people. At first, I was a bit nervous, so when I knocked at the door, my heart was beating very fast. A lady came out, and I said carefully to her, “Trick or treat.” My voice was very low, and even myself could hardly hear it. To my surprise, the lady was so kind to give me two candy bars, and I was so excited, t hanked the lady and moved on. I couldn’t remember how many houses I visited, but I could remember how many candies I got—I got 91 pieces of candy that day, and I was so proud of myself.What a happy Halloween I had! And I wish we could have a Halloween every month!根据短文内容,完成句子(每空一词,1分)。

I can still remember the first Halloween holiday I had in the USA.On the morning of Halloween, we paid a visit to a pumpkin farm. Each of us brought a pumpkin to school with us. I used the pumpkin to make a lantern which had two triangle eyes and a scary mouth.In the afternoon, we put on the Halloween costumes and went on parade in school. Some of the costumes were nice, but some of them looked scary. I chose to wear a suit of Superman’s clothes.I did a lot of things that day, but the part I liked best was ―trick or treat‖ in the evening. After dinner, I went outside with an empty bag. I hoped to get a lot of candies from people. At first, I was a bit nervous, so when I knocked at the door, my heart was beating very fast. A lady came out, and I said carefully to her, ―Trick or treat.‖ My voice was very low, and even myself could hardly hear it. To my surprise, the lady was so kind to give me two candy bars, and I was so excited, thanked the lady and moved on. I couldn’t remember how many houses I visited, but I could remember how many candies I got—I got 91 pieces of candy that day, and I was so proud of myself.What a happy Halloween I had! And I wish we could have a Halloween every month!根据短文内容,完成句子(每空一词,1分)。
