第一节阅读理解 (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A、B、C和D项中,选出最佳选项,并填写在答题卡上。

Linda often asked Luke to dinner. Linda loved Luke, but Luke loved Linda’s cooking, not Linda herself. Linda accepted that for the time being. But she felt that, with enough meals and enough time, she would get her man.

Luke rarely stayed more than ten minutes past the last bite of dessert. Linda would ask luke if he wanted to watch TV, or play cards or chess, or take a walk around the neighborhood, but Luke always declined. He always said, “ I’ve got to go.” They both knew that Luke didn’t have to go anywhere. All he ever did was to go back to his apartment and read books or go online.

Tonight was probably going to be more of the same. But Linda was a patient woman. She loved to cook, and she loved to watch people eat her cooking. Tonight she prepared shrimp, fresh green beans, mashed potatoes, and asparagus(芦笋). Luke ate everything. Then she brought out her homemade cheesecake with vanilla ice cream for dessert.

Luke asked, “ Are you trying to fatten me up for something? Every time I come over here, I have to eat celery(芹菜) and lettuce for a week to get back down to my normal weight. Or maybe I should start going to the gym more often. Nah, I’m too lazy for that.”

“Oh, stop exaggerating(夸张).” Linda replied. “ You enoy every mouthful. And besides, I don’t think you lazy at all.”

“ You’re right. I apologise. I love your cooking, and if you didn’t invite me over here, I’d be hurt and hungry.”

Linda watched contentedly(满足地) as Luke devoured the cheesecake and ice cream. Someday, she thought, I will be his dessert.
