Coca-Cola seems determined that Slice's sales won't come at the expense of Sprite. ( )
A、strengthened
B、brittle
C、to have a strong will
D、weakened
【正确答案】：C
【题目解析】：句意：可口可乐公司似乎下定了决心，不能用牺牲“雪碧”来换取“斯来思”的销售额。determined意为“下定决心的”。选项中strengthened意为“加强的”；brittle意为“脆的，易碎的”；to have a strong will意为“意志坚定”；weakened意为“变弱的”。故本题选C 。
