Question

1,(1)i left school as soon as i can and started work .
(2)after having a short rest there and sharing with the food we had brought ,we started going down.
这句话中,（1）需要把can改成could,（2）需要把with去掉,然而,为什么（1）中started work 用start do形式而（2）中 started going 用start doing形式?
2,i was in great pain at that moment,but i tried to act as if nothing has happened until the class was over .
这句话中哪里错了?
3,i felt as if flying like a superman .
这句话有错么?是不是felt as if flying 中有错?
4,in the end,i got to the finishing line first..
这句话中,是否需要把first.改成firstly?

Answer 1

1.因为这句话的时态是过去式,left,started都表明是过去式,另外,连词and前后时态应该一致.
share意为分享；share with 意为与.分享,后面接人,而这句话后面接的是物the food,因此,要把with 去掉.
start to do 和start doing 都为开始做某事,前者start为不及物动词,后者start为及物动词,这里work为名词,工作.
2.has改为had,as if 从句用虚拟语气时,从句表示与过去事实相反,谓语动词用“had＋过去分词”,这里他实际上是疼,却表现的好像什么都没发生似的,另外,at that moment表过去,因此,has happened 改为has happened.
3.i felt as if flying like a superman 这句是省略句,原句为i felt as if i am flying like a superman .没有语境,看不出哪有错.
4.不能将first.改成firstly,first为第一的意思,而firstly 为首先的意思.这句话为“最后,我第一个到达终点”.
