不费劲地

It tires not nor does it boast of its power; but belongs to the air, travelling it may be six thousand miles to and from its northern nesting home feeding its flown young as it flies and slipping through a medium that seems to help itspassage even when the wind is adverse.

它不知疲劳，也不夸耀自己的飞翔能力，然而它在空中十分自如，可以一直飞行6，000英里。飞向北方的筑有鸟巢的家乡以及从那里飞走，在飞行的过程中还要喂养已出窠的雏燕，甚至在顶风的时候也能够不费劲地穿过那似乎有助它迁栖的气流。

Medium 的含义是"介质",没有这种"介质"便达不到一定的目的 It tires not nor does it boast of its power; but belongs to the air, travelling it may be six thousand miles to and from its northern nesting home feeding its flown young as it flies and slipping through a medium that seems to help itspassage even when the wind is adverse.

我认为哪一天要是我不能提起一只脚登上一级台阶，再费劲地拖上另一只脚--如此重复14次直到精疲力竭，那我就完了--那时我只能承认我失败了，可以躺下来等死了。

J e neither lose the filberts,nor drow back his hand.so crying loadly.one stranger fand the way of question solved.and said to him,"all right, child,donot be sad.it should be content with own half' you can fetch out you hand with a wet finger."

他既不想丢掉坚果，却又不能缩回手，于是就放声大哭起来。一个路人看出了问题的所在，就对他说：&好啦，孩子，别那么贪心！能拥有一半就知足的话，你就能毫不费劲地把手拿出来了。&

Now, if words and images came to me without effort, it is a pretty sure sign that they are not the offspring of my own mind, but stray waifs that I regretfully dismiss.

现在，如果有什么文思毫不费劲地涌入我的脑海，那我敢断定，它一定不是我头脑中的产物，而是从别人那里捡来的东西。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
