additional mouths怎么翻译？（20181014长难句）

【昨日回顾】

Taking all this into account, what might we reasonably estimate supermarkets to be like in the year 2001?  To begin with，the world food supply is going to become steadily tighter over the next thirty years—even here in the United States.

考虑到所有这些因素，我们可以适当地估计一下2001年的超市将会是什么样子呢? 首先，今后的30年内，世界的食品供应日益紧张，甚至美国这里也不例外。

Never give up any opportunity to make progress!

We, never met, always love in mind!

【今日长难句】

By 2001, the population of the United States will be at least two hundred fifty million and possibly two hundred seventy million, and the nation will find it difficult to expand food production to fill the additional mouths.

【重难点词汇】

expand food production 扩大食物生产

fill 满足，填满

additional 多余的，额外的

【参考译文】

By 2001, the population of the United States will be at least two hundred fifty million and possibly two hundred seventy million, and the nation will find it difficult to expand food production to fill the additional mouths.

到2001年美国人口将至少达到2亿5千万，也可能是2亿7千万。那时，美国将很难扩大食品生产来满足人口增长的需要。

【翻译提示】

对于复杂句而言，脱离语境的逐字翻译的译文就是“笑话”，例如 fill the additional mouths 如果逐字翻译，就是“填满多出来的嘴”，What？ 这是人话吗？显然结合语境，应译为：满足人口增长的需求。但你如果脱离句子去背单词，你能背到fill 表满足吗？你能背到additonal mouths 表人口增长吗？

【分子分析】

1. 句子主干为and连接的并列句：the population will be two hundred fifty million and possibly two hundred seventy million, //and//the nation will find it difficult to expand food production；前半句为主系表结构，后半句为主谓宾宾补结构。

2. …find it difficult to … ：it为形式宾语，to do sth. 为真正宾语

3. by 2001为句子的时间状语；at least 修饰 two hundred fifty million；目的状语：to fill the additional mouths 修饰to expand food production

【明日长难句】
