1.In this text, did you notice the word “farming”? What’s the difference between “farming” and “farm”? Let’s look at a sentence first.
The farmers live by _______.(farm,farming) (Which word will you choose?)
Yes,“farming” is the correct word.
Farm: an area of land, together with its buildings.
Farmland: only the land for farming.
Farming: working on the farm.
To farm : to do farm work
1).They like to eat _______. 2).They live by________.(fish,fishing)
2.work out: The FAO has worked out that up to 30% of food is lost in storage.
a)work out 一词的“新词义”曾经出现在2001年高考“单项真空”中，现在，可结合Lesson14的内容，试用work out的“新词义”造句如下：
Various things have been done to increase the food supply in the world. But at first they all seemed unlikely to be of any efficiency at all. However, dozens of years have passed and most of the efforts seem to be working out far better than most of the optimistic people expected.
b)work at, work on, work out
work at和 work on都有“从事……”的意思。
在此意义上，两者可以换用。如：
Is Tom still working at / on the new novel that he promised?
work at 还有“在……工作”的意思。如：
How long have you been working at this school?
work on 还有（激起人的感情等）“对……起作用，影响……”的意思。如：
The sight of so much suffering worked on our hearts so that we were filled with pity.
这么多受难的情景时震憾了我们的心，我们心中都充满了同情。
work out 表示“计算出，解决（问题）”等意思。如：
Can you work out how much it costs to feed a common family?
I can’ t work out this sum.
work out 还有“想出，弄清楚（常用于否定句）”等意思。如：
We must work out a better method of saving money.
I can’t work out the meaning of this poem. 1. order的用法
