　　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：

　　work at 还有“在……工作”的意思。如：

　　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.

　　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

　　StepV.Phrases

　　Be suitable for day by day up to 30% ruin in storage starve to death be likely to do attack various things

　　参考文档1

　　只有11%的地球表面适合种庄稼(be suitable for)，而且这个面积还在日渐减小(day by day)。高达30%的食品在存储时丢失(up to)。存储的食品被雨，老鼠不断的毁坏(ruin,in storage)。每年都有大量的人们因饥饿而死亡(starve to death)。人们正在尝试很多办法来增加粮食供给。科学家正在发明新的植物，这些植物不容易被害虫侵害(attack,pest) 。

　　参考译文：Only 11% of the earth’s land surface is suitable for growing crops.And this area is becoming smaller and smaller day by day.It’s worked out that up to 30% of food is lost in storage.Food stores are frequently ruined by rain ,or eaten by mice.Every year a great number of people starve to death.People are trying various ways to increase food supply.Scientists are developing new types of plants which are less likely to be attacked by pests and diseases.

　　feed the world

　　A food scientist is discussing the main types of food crops.( S=scientist; I=interviewer)

　　I: One of the most important food crops in the world of course is rice. Why is it so important?

　　S: Well, for one thing, everyone can eat it, and it’s suittable for sick people and young children.

　　I:Is it grown all over the world?

　　S: No. It needs a hot climate and lots of water.So it can’t be grown in cold countries or where there is little water. But where the conditions are right, you can grow three rice crops in a year.

　　I: Can you live on rice alone?

　　S: No.It doesn’t contain all the foods a body needs to stay healthy.Also it’s better to eat the whole grain, but in many parts of the world it’s the custom to remove the brown outside part of the grain. I: What about the potato?

　　S:Well,the potato is a very good food for the human body. So you could live for six months just by eating potatoes. In a year, you would also need to eat a little fat and some fresh fruit to stay healthy.

　　I:Where are potatoes grown?

　　S:They can be grown in cold countries , like the north of Europe and up in the mountains of South American , where the potato came from.

　　I:What about bread?

　　S:Bread can be made from different grains. It’s an important food in the north of Europe where it’s cold but also in the Middle East.It’s a very good food,but you need to eat other foods like fresh fruit and vegetables to stay healthy.

　　I:Are there any other foods we haven’t mentioned?

　　S:Yes, there’s Indian corn. This came from America, but is now a very important crop all over the world. You need a warm sunny climate to grow maize , but it doesn’t need as much water as rice. Mind you, if you water your maize, you will get a better crop.

　　I: And we haven’t mentioned noodles.

　　S: No. Very important!Noodles and pasta are both made from a type of hard grain . thje grain is turned into a powder, mixed with water and then formed into different shapes. In Asia and the Middle West these are called noodles and in Italy these are called pasta.

Her granddaughter took up the book and opened it. “Why, it’s just blank pages!” she cried in 15 .

　　John's face turned 16 . Then the girl understood. There never was a book. Grandma couldn’t hear the little bell when the typewriter came to the 17 of the line.
