6.As Dr Yuan proves,one dream is not always enough,especially for a person who loves and cares for his people.

　　从袁博士身上可以看到,一个梦想不总是够的,特别是对一个为人民着想的人来说更是如此。

　　剖析:as Dr Yuan proves是非限制性定语从句,as作为关系代词作proves的宾语,意为"正如"；not always是部分否定,意为"不总是......"；especially意为"尤其是"；注意比较:specially(专门的,特别地)；care for意为"关心"。

　　7.It seems a strange name since all crops are organic no matter how they are produced.

　　这个名字看起来有些奇怪,所有的农作物,无论是如何生产出来的,都是有机物。

　　剖析:It代替chemical farming;since引导原因状语从句,意为"既然",no matter how...是这个原因状语从句中的让步状语从句。

　　8.When farmers use this kind of natural fertilizer they keep the air,soil and water as well as the food supply free from chemicals.

　　农民使用这种天然肥料能保持空气、土壤、水以及食物来源不受化学物质的污染。

　　剖析:as well as连接并列宾语air,soil,water,food supply,意为"不仅食物来源,空气、土壤和水也......"；free from...是宾补,意为"没有;免于；无......之忧"。

　　9.These put the minerals back into the soil,making it rich and healthy and ready to grow crops that need rich and fertile soil like corn or wheat.

　　这些农作物将矿物质带回土壤,使之肥沃、宜于健康,适宜于种植要求土壤肥沃的农作物,例如玉米或小麦。

　　剖析:making...是现在分词短语作结果状语；that need...是定语从句修饰crops。

　　10.But whatever they grow they make sure that what is left in the ground after harvesting becomes a natural fertilizer for the next year's crop.

　　但无论他们种什么,他们确保在收割后留在地里的东西会成为来年农作物的天然肥料。

　　剖析:whatever they grow是让步状语从句,相当于no matter what they grow；make sure that...意为"确保......"；what is left in the ground after harvesting是that从句中的主语从句。
