谁帮我做下这个短文改错
One day the sun was very strong,Jim was so tired
to walk.There was no trees near the road ,so he rested
under a big rock.After drinking some water ,he took his
shirt,lay down on the ground and fall asleep at once.
he was very tired that he didn't wake up until the evening.
he was just about to jump while he felt something moving
near his feet.He looked up and saw a long black snake.
Jim was so frightening that he didn't dare to move .The
snake began to crawl across his legs.It crawled on and
on until it was disappeared under the rocks,Jim jumped
to his feet, picked up his shirt and ran down the road.
并解释一下为什么那么改

答案

不是十行吗?怎么变成十一行了?
1.so → too
too和后面的to构成too...to...结构,意思是“太...而不能...”
2.was → were
后面的trees是复数,所以谓语动词也用复数形式
3.took和his中间加入off
固定短语take off,意思是“脱下...”
4.fall → fell
and后面的fall是并列谓语,所以和took/lay一样用过去式fell
5.very → so
和后面的that构成so...that...结构,意思是“如此...以至于...”
6.while → when
此处when为并列连词,意思是“就在这时”= and then,引导并列句,而不是时间状语从句
7.up → down
“蛇在脚边”,当然是look down“向下看”,而不是look up“向上看”
8.frightening → frightened
frightening意思是“令人害怕/恐惧的”,frightened意思是“感到害怕/恐惧的”
9.正确
10.去掉was
disappear是不及物动词,没有被动语态,所以它直接做谓语,不能再在其前加上be动词was
11.正确
