Unit 3Computers话题：网上购物体裁：议论文(分析利弊型)写作思路：表明观点(网购有利有弊)；分析利弊。Online shopping is becoming more and more popular.But like everything else，it has its advantages and disadvantages.On one hand，it is convenient and time­saving because we don't really go out to shop.Besides，there are so many choices that we can compare different items carefully and it is possible for us to buy something good at low price.On the other hand，as we can't see the real objects online，we are likely to buy fake products easily.What's worse，sometimes we have to wait a long time before we can get the goods we buy due to the slow delivery.As far as I am concerned，we should take a correct attitude towards online shopping to maximize its advantages and minimize its disadvantages.写出下列必考单词1算术题；总数； 金额 n_2(电脑)操作员；接线员

was walking around in a store，when I saw a cashier (收银员) handing some money back to a little girl.“I'm sorry，but you don't have enough money to buy this doll，” the cashier said.I walked toward her and asked her whom she wished to give this doll to.“It's the doll that my younger brother loved most，but he has gone to be with God.Daddy says that Mommy is going to see God very soon，so I need Mommy to wait for me and give the doll to my brother.”Then she showed me a very nice photo of herself.She was laughing in it.She then told me，“I want Mommy to take my picture with her，so she won't forget me.”I quickly reached for my wallet and said，“Suppose we check again，just in case you do have enough money for the doll.OK？”“OK，” she said.I added some of my money to hers without her seeing and we started to count it.There was enough for the doll and even some spare money.The little girl said，“Thank you，God，for giving me enough money！”Then she looked at me and added，“I asked last night before I went to sleep for God to make sure I had enough money to buy this doll，so that Mommy could give it to my brother.He heard me！”“I also wanted to have enough money to buy a rose for my Mommy，but I didn't dare to ask God for too much.However，he gave me enough to buy the doll and a rose.”问题：1What did the girl_ask_for_God_before she went to sleep?2What did the girl want to buy for her mother?3Why did the girl
