[原创]两道语法题，原文已贴。

单复数问题：
200308-Structure 23
THE water of the Atlantic, Pacific, and Indian Oceans MAKE UP 70.8 percent TO the Earth;s surace.
大写部分为划线部分：答案选“TO”.但是“MAKE UP”为什么不改为“MAKES UP OF”,即“组成”之意。况且，THE WATER 是单数名词，谓语动词应该用单数

199305
Structure:
Direct mail advertising serves to acquaint customers with products, alert them to new opportunities, and PAVING the way for other sales activities.
正确答案是：把paving 改为pave。
疑问：为什么不改为paves, 应该与serves的单复保持一致。
