有四个正面的

This morning, I took a bullhead fish and ride toward to the old factory rapidly, I found the cat lying under the megranate tree, in front a shed from a building's windows threw several case layer upon layer on the ground, there are three or four paper cases had been thrown out the building's window, when I saw this scene, my first idea is about the little cat, if the scene had been in n years ago, Teacher Huang should say to another young teacher Huang and me for we had been in favor of raising many ducks:" You have the catface of mother loving!"

今天天气晴好，早上，我带了大头鱼，朝老厂区的方向迅速地骑车，找到了正卧在石榴树下面的猫，前面车棚前的大楼楼道里往窗外扔下重重的纸盒箱，有三四个纸箱已经被扔了出来，看见这幅场景，我的第一个念头是想到了那只小猫，如果在 n ……年前，黄老师一定会对我另一位年轻的黄老师对养鸭子的爱好程度给予有力的讽刺的："母爱的畸形变态！"

Bout three months ago my cousin Bud, fourteen year old, was riding through the woods on t'other side of the river, and didn't have no weapon with him, which was blame' foolishness, and in a lonesome place he hears a horse a-coming behind him, and sees old Baldy Shepherdson a-linkin' after him with his gun in his hand and his white hair a-flying in the wind; and 'stead of jumping off and taking to the brush, Bud 'lowed he could outrun him; so they had it, nip and tuck, for five mile or more, the old man a-gaining all the time; so at last Bud seen it warn't any use, so he stopped and faced around so as to have the bullet holes in front, you know, and the old man he rode up and shot him down.

大概三个月前，我的堂兄弟、十四岁的勃特骑着马，穿过河对面的林子。他身边没有带武器，这真是他妈的再傻也没有了。在一处偏僻的地方，他听得身后有马声。一看，是巴第·歇佛逊老头儿，手里拿着枪正飞快赶来，一头白发迎风乱飘。勃特并没有跳下马来，躲到树丛里，反倒让对方赶上来。于是，两人赛开了，一个在前飞奔，一个在后紧追，足足奔了五英里多路，老头儿越追越近。到最后，勃特眼见自己没有希望了，便勒住了马，转过身来，正面朝着人家，于是一枪打进了胸膛。你知道吧，老头儿赶上前来，把他打倒在地。
