《新概念英语第二册》Lesson49-53课文注释
《新概念英语第二册》Lesson49-53课文注释新概念英语第二册课文注释Lesson491.Tired of sleeping on the floor, a young man in Teheran saved up for years to buy a real bed. 德黑兰的一个年轻人由于对睡地板感到厌倦，于是积蓄多年买了一张真正的床。
(1)tired引导的分词短语省略了开头的being，其作用相当于原因状语从句：As he was tired of…。
sleeping为动名词，作介词of的宾语。
(2)save up为固定短语，表示“储蓄”、“攒钱”：I want to get married in one or two years, so I'm trying to save(some money)up.我想一两年之间内结婚，所以我在设法攒钱。
(3)to在这里用于表示目的，相当于in order to：I got up early to have a swim.为了游泳我起了个大早。
2.…he carried the bed on to the roof of his house.……他便把床搬到了他的屋顶上。
介词onto可拼写成一个词，也可拼写成两个词(on to)。
它用于表示动作方向而不用于表示静态的位置(与into相似)：I put the pen onto/ on the table.我把笔放到桌子上。
The pen is on the table.笔在桌子上。
(不可用onto/ on to)onto/ on to有时可用on代替，但表示位置的on不可用onto代替：Mr. Thompson jumped onto the stage.汤普森先生跳上了台上。
Mr. Thompson jumped on the stage.汤普森先生在台上跳了跳。
3.A gust of wind swept the bed off the roof…一阵大风把床从屋顶上刮了下来……gust表示“一阵强风”、“一阵狂风”，既可以单独使用，也可以用a gust of wind形式：A gust(of wind) blew my hat off.一阵大风吹掉了我的帽子。

What caused the fire?At last firemen have put out a big forest fire in California. Since then, they have been trying to find out how the fire began. Forest fires are often caused by broken glass or by cigarette ends which people carelessly throw away. Yesterday the firemen examined the ground carefully, but were not able to find any broken glass. They were also quite sure that a cigarette end did not start the fire. This morning, however, a fireman accidentally discovered the cause. He noticed the remains of a snake which was wound round the electric wires of a 16,000-volt power line. In this way, he was able to solve the mystery. The explanation was simple but very unusual. A bird had snatched up the snake from the ground and then dropped it on to the wires. The snake then wound itself round the wires. When it did so, it sent sparks down to the ground and these immediately started a fire.参考译文消防队员们终于扑灭了加利福尼亚的一场森林大火。
