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?
