今天来看一句话里学到的一些表达：
Three of them dismounted, one stayed in the saddle, his rifle ready, his eyes trained away from the house to the left and to the right, because likely as not the fugitive would make a dash for it.
Expressions
1. dismount 下车、下马
If you dismount from a horse or a bicycle, you get down from it.
可以理解为get off
2. train
aim or direct at; as of blows, weapons, or objects such as photographic equipment
例句：
"He trained his gun on the burglar"
" Don't train your camera on the women"
这个词我们一般被熟知为名词火车、动词训练。在文中有瞄准、朝着的意思。
3. likely as not
(as) likely as not = most likely 或者 very likely 表示很可能，多半、或许
例句：
"It's perfectly normal and likely as not to be correct in the longer term, if this is still a secular bear market."
"Mr. Norman will help you,as likely as not"
4. make a dash
dash 做名词的时候表示破折号，也有猛冲、撞击的意思，也作动词猛冲、撞击
make a dash 表示猛冲、撞击，类似的表达还有make a final dash 最后冲刺
原文：
Three of them dismounted, one stayed in the saddle, his rifle ready, his eyes trained away from the house to the left and to the right, because likely as not the fugitive would make a dash for it.
