“It’s perfect for　 39　 ,” my mother continued. “I　 40　 someone had made a dress like this for me.”

　　　 41　 you can’t wear it, I thought. But I knew Mom had spent a lot of time on the dress. Only the world’s most　 42　 daughter would refuse. reluctantly(不情愿的). I put it on.

　　 All through church I prayed, Lord, let me get out of here __43　 anyone seeing me. Especially Dennis Pearce, the boy I had a crush on. He was one of the cutest (bright) guys at Neptune High. Although we were in some of the same classes, Dennis had　 44　 taken any notice of me.

　　 At the end of the service I　 45　 for the door. But I had to wait on the　 46　 while my parents chatted with their friends. Just a little while longer… Then　 47　 the corner of my eye I saw the Peace approaching.　　 48　 I could escape, Dennis was right beside me.

　　 I started gabbing a mile a minute, hoping if I kept it　 49　 he wouldn’t notice my horrible dress. “I am going to college in September,” I said.

　　 “That’s great,” Dennis replied. “I got　 50　 to the police academy.”

　　 “Wow!” I said.　 Somehow I kept the conversation going. Soon we were walking to the parking lot together. The next thing I knew Dennis had first asked me　 51　 .

　　 We courted through college, and eventually got married. Months after our wedding I asked Dennis if he remembered the day　 52　 he had first asked me out.

　　 “_ 53　 bet I do,” he said. “You were always　 54　 in school, almost standoffish (coldhearted). I didn’t think you’d be much fun. But you were so animated (lively) when we talked on the church steps, I wanted to get to know you better.” Maybe that　 55　 yellow dress wasn’t what I would have chosen, but that day it was the perfect dress for me.

8．(9分)在一定温度下，将8 molSO₂和4 molO₂放入密闭容器内进行反应：

2SO₂(g) + O₂(g) 　2SO₃(g)

(1)如果原容器内的压强为3×10⁶ Pa,平衡时SO₂的转化率为80%，求平衡时容器内的压强．
