题目

A: Did Mary have a fever?B: No, she didn't. ________. She ate too much ice-cream, which made her stomach uncomfortable. 答案：【答案】She had a stomachache【解析】句意：A：Mary发烧了吗？B：不，她没有。她胃疼。她吃了太多的冰淇淋，这使她的胃不舒服。根据“She ate too much ice-cream, which made her stomach uncomfortable”可知，是胃疼，have a stomachache表示“胃疼”，根据“didn't”可知，动词要用其过去式，故填She had a stomachache。下列二元一次不等式组可用来表示图中阴影部分表示的平面区域的是（　　）A．x+y-1≥0x-2y+2≥0B．x+y-1≥0x-2y+2≤0C．x+y-1≥0x-2y+2≤0D．x+y-1≤0x-2y+2≥0
