问题补充：

She is too thin. She gain some weight but she too little.

A. would; ate

B. will; eat

C. would; eats

D. will; ate

答案：

@@A. would; ate@@B. will; eat@@(答案→)C. would; eats@@D. will; ate

解析：根据第一句She is too thin所给的信息可以知道，“她瘦”是客观事实，所以“吃得少”也是客观事实，因此用陈述语气的eats。那么“体重增加”则应该是一种假设（注意句中的转折连词but），所以第一个空要填would。本句可以理解为其后面省略了一个条件从句if she ate more。
