河南省顶级名校2015届5月热身模拟英语试卷(2) (本试卷共120分,考试时间100分钟) 第一卷 第一部分听力部分(略) 第二部分阅读理解(共两节,满分40分) 第一节(共15小题;每小题2分,满分30分) 阅读下列短文,从每题所给的四个选项(A, B, C和D)中,选出最佳选项.并且在答题卷上将该项涂黑。 A My grandparents were married for over half a century, and played their own special game the time they had met each other. The goal of their game was to write the word “shmily” in a surprise place for the other to find. They took turns leaving “shmily” around the ho use, and as soon as one of them discovered it, it was their turn to hide it once more. They dragged “shmily” with their fingers through the sugar and flour containers to await whoever was preparing the next meal. “Shmily” was written in the steam left on t he mirror after a hot shower, where it would reappear bath after bath. There was no end to the places where “shmily” would pop up. Little notes with “shmily” were found on car seats, or taped to steering wheels. The notes were put inside shoes and left und er pillows. “Shmily” was written in the dust upon the mantel(壁炉架)and traced in the ashes of the fireplace. This mysterious word was as much a part of my grandparents’ house as the furniture. It took me a long time before I was able to fully appreciate my grandparents’ game. Skepticism has kept me from believing in true love—one that is pure and enduring (持久的). However, I never doubted my grandparents’ relationship. It was based on passionate affection which not everyone is lucky enough to experience. But there was a dark cloud in my grandparents’ life: my grandmoth er had breast cancer. The disease had first appeared ten years earlier. As always, Grandpa was with her every step of the way. He comforted her in their yellow room, painted that way so that she could always be surrounded by sunshine, even when she was too sick to go outside. But my grandmother grew steadily weaker until, finally, she could not leave the house any more. Then one day, what we all dreaded finally happened. Grandma was gone. “Shmily.” It was written in yellow on the pink ribbons of my grandmother’s funeral bouquet (花束). As the crowd thinned and the last mourners turned to leave, Grandpa stepped up to my grandmother’s coffin and, taking a shaky breath, he began to sing to her. Through his tears and grief, the song came: S-h-m-i-l-y: See How Much I Love You. 21. The first paragraph is mainly about ________. A.what the word “shmily” means B.how the author’s grandparents played their special game C.how the author appreciated her grandparents’ game D.how the author’s grandparents cared for each other 22. The underlined phrase “pop up” in Paragraph 1 means ________. A. appear B. change C. survive D. work
