Firemen had been fighting the forest for nearly three weeks before they could get it under control. A short time before, great trees had covered the countryside for miles around. Now, smoke still rose up from the warm ground over the desolate hills. Winter was coming on and the hills threatened the surrounding villages with destruction, for heavy rain would not only wash away the soil but would cause serious floods as well. When the fire had at last been put out, the forest authorities ordered several tons of a special type of grass-seed which would grow quickly. The seed was sprayed over the ground in huge quantities by aeroplanes. The planes had been planting seed for nearly a month when it began to rain. By then, however, in many places the grass had already taken root. In place of the great trees which had been growing there for centuries patches of green had begun to appear in the blackened soil.

get it under control表示“使它得到控制”，get有“使……处于某种状态”的含义：
You'd better get your dog under control.
The Government can no longer keep prices under control.政府已控制不住物价。
2．for miles around,方圆数英里。
This is the only modern building for miles around.
3．Winter was coming on and the hills threatened the surrounding villages with destruction…冬季即将来临，这些山丘对周围的村庄具有毁灭性的威胁……
When spring comes on, there will be flowers everywhere.
I was still in the forest when night came on.
The thief threatened him with a knife.
Then whole village is threatened with destruction.
4．…for heavy rain would not only wash away the soil but would cause serious floods as well.……因为大雨不仅会冲走土壤，而且还会引起严重的水灾。
（1）for引导的句子与前面的两个分句为并列句，用于陈述原因。heavy rain这个主语之后是由not only… but… as well连接的两个谓语。与并列连词 not only…but(also)的含义一样，not only…but…as well也表示“不仅……而且……”，用于连接并列句，只是as well通常位于句尾。试比较：
He not only washed the car, but (also) polished it.
He not only washed the car, but polished it as well.
A wooden bridge was washed away by the flood.
I can't wash the spot away.
5．in huge quantities,大量地。
They drank a large/great/small quantity of beer last night.
He bought books in (large) quantities.
He has quantities of books/stamps.
6．… in many places the grass had already taken root.……很多地方的草已经生了根。
This type of grass takes root easily.

7．In place of the great trees which had been growing there for centuries, patches of green had begun to appear in the blackened soil.一片片的绿草开始出现在这片烧焦的土地上，代替了多少世纪以来一直生长在那里的参天大树。
（1）in place of表示“代替”、“取代”：
Jane answered the phone in place of Mary.
（2）介词短语 in place of的宾语是trees。trees有一个which引导的关系从句，which在从句中作主语，不可省略；从句中的时态为过去完成进行时。（cf．本课语法）
There are patches of cloud in the sky.
What is that yellow patch on the wall?
The smoke has blackened the walls.
