题型描述: 阅读理解Girls dream of having the perfect wedding, but when I got engaged, I have up any dream of the perfect day. My mother has to have her own way. She’s a very nice woman, but sheˊs convinced that what she wants is exactly what you want, and you cannot tell her otherwise. Since my parents were paying for the wedding, I kept my mouth shut, and let her decide everything! I was not married in church, but in the same hall where my brother was married. It had recently been remodeled, and all the charming features, such as a large stone fireplace, were removed. She insisted that my cousin make my wedding dress. I wanted a simple long white dress with long sleeves. My cousin made a short dress without sleeves. My cousin also added a HUGE bow on the back of the dress that looked as if I sat in a wedding cake! My mother also insisted on making the cake, but she ran out of time to frost (给…覆上糖霜) it, and a huge, plain cake was served. I wanted a single rose for a bouquet (花束); my mother insisted that my sister, a florist (花店店主), make me a huge bouquet of lilies (百合花), which I am allergic to! My mother referred to this as “my daughter’s dream wedding”. Dream wedding? More like a nightmare!1.Why couldnˊt the author dream of having the perfect wedding?A. Because she was very poorB.
