分析 这是一篇关于一个学生考试迟到的事。短文一开始就是电话铃声,Sam应该起来接电话,所以第l空中应选D,这四个动词中只有answer能表示“接电话”这个含义。第2空中要选择一个副词,句中已含有still at home等状语,故不能选择when,where, how表示方式,如用在本句中则句意不通,所以选A。第3空,从后文知,Sam是到学校去,故应选C。对于学生来说,exam是学生最可能要做的事,并且后文说到其他学生在writing。第4空,get dressed意为“穿衣服”,要注意这个短语的完整性。第5空,从前一句中的动词leave以及后文中的一系列动作可知,本空中应填remembered才符合逻辑,其他词不能使文章通顺。第6空要注意分析备选项的意义;从后文he had not put away his books可知选B最合适,因书应该是放在课桌上。第7空中应填fast,因Sam 要迟到了。第8空中要注意在形容词后接writing,故选busy。第9空,从上文知,Sam 已经迟到了,故老师应问他迟到的原因,选A。第10空表明Sam的态度,他害怕抬头看老师,故选up。第11空,Sam所陈述的理由是闹钟未响,故填failed。第12空,从上文Sam的话没说完知道这时老师打断了他的话,故选stopped。第13空,Sam 在教室里走去的当然是seat。第14空,本空说明Sam 思维混乱,不能思考,选A。第15空,综合上文可知Sam 感到这一天太糟糕,故选B 。

I am sitting in an empty football field after my last high school football game that finished a few hours ago. I’m the mid-field player on my team. But in fact that’s not 1 now. I was the mid-field player because, as I said, this was my 2 game. That’s a good way to end a high school football career (生涯), especially if you win, but even though you don’t, it’s 3 to leave at a high point.
I was eight when I first started playing football. My dad 4 football, and he used to practise with me at home – passing, catching, running. We used to practise
almost every evening 5 it got too dark. He tried to teach me everything he knew about the 6 . “Just remember: don’t ever 7 .” “Stay in the game. Don’t lose your concentration (专注).” “Go out there and give 110 percent every time.” Well, that was a long time ago, but I still hear his words 8 in my ears.
I had a lot on my mind 9 the game today. I don’t like things to end, I guess, and this was the last game. I was talking to myself and warning myself about what to do and not to do. I didn’t sleep at all 10 , and when the sun came up this morning, I reached the point where 11 just wanted it all to be over, finished, done. But then when the game started, my mind became 12 . I just lived in this game, this moment. I didn’t hear the crowd, I didn’t feel the cold or the pain, I never felt tired. I just kept my eyes on the 13 , and it was just me and the ball and, inside, a soft, white light 14 me the way to the goal. It was a beautiful, empty feeling.
It’s all over now, and it’s really getting cold here. It’s starting to snow. The sun’s almost gone, and I can 15 see the goal. Now it’s dark and I’m sitting here all alone. Well, I guess it’s time to say good-bye and move on.

They all went into the studio(摄影棚). " All right," the director said, "now our players are going to say goodbye. Run the film backwards through the projector so that we can 13 the 'sunset' behind them."
The "sunset" began, 14 after a quarter of a minute, the director suddenly put his face in his hands and shouted to the men to stop.
The birds in the film were flying backwards, and the waves(波浪) on the sea were 15 the beach(海滩).
