A. Help yourself B. It’s up to you

　　C. That’s the point

　　D. It’s a deal

　　【解析】选B。考查交际用语。句意: ——给服务员合理的小费应该是多少呢? ——你自己做主, 我通常给用餐价格的20%。所以选It’s up to you。Help yourself“自便”; That’s the point“这正是问题的关键”; It’s a deal“成交”。

　　【拓展延伸】英语情景交际“你说了算”大聚会

　　(1)It’s all up to you. 全听你的了。

　　(2)You are the boss. 你是老板(你说了算)。

　　(3)You have the conn. 你说了算。

　　Conn本来是“掌舵”的意思, 后来被当名词用, to have the conn就是负责控制舰艇行驶的方向, 也就是“有决定权”的意思。

　　(4)You have the final say. 你决定吧。

　　(5)The final decision is yours. 你做最后定夺吧。

　　(6)You are in charge here. 你是这里管事儿的。

　　. 完形填空
