So, smile away!继续微笑

The thing that goes the farthest toward making life worthwhile, that costs the least and does the most, is just a pleasant smile.
那最能赋予生命价值、代价最廉而回报最多的东西，不过一个令人心畅的微笑而已。

The smile that bubbles from the heart that loves its fellow men, will drive away the clouds of gloom and coax the Sun again.
由衷地热爱同胞的微笑，会驱走心头阴郁的乌云，心底收获一轮夕阳。

It's full of worth and goodness, too, with manly kindness blent; It's worth a million dollars, and it doesn’t cost a cent.
它充满价值和美好，混合着坚毅的仁爱之心；它价值连城却不花一文。

There is no room for sadness when we see a cheery smile; It always has the same good look; it's never out of style; It nerves us on to try again when failure makes us blue;
当我们看到喜悦的微笑，忧伤就会一扫而光；它始终面容姣好，永不落伍；失败令我们沮丧之时，它鼓励我们再次尝试；

The dimples of encouragement are good for me and you.It pays the highest interest — for it is merely lent;
鼓励的笑靥于你我大有裨益。它支付的利息高昂无比──只因它是种借贷形式；

It's worth a million dollars, and it doesn’t cost a cent.
它价值连城却不花一文。

A smile comes very easy — you can wrinkle up with cheer. A hundred times before you can squeeze out a salty tear. It ripples out, moreover, to the heartstrings that will tug, and always leaves an echo that is very like a hug.
来一个微笑很容易──嘴角欢快翘起来，你能百次微笑，可难得挤出一滴泪；它的涟漪深深波及心弦，总会留下反响，宛若拥抱。

So, smile away! Folks understand what by a smile is meant. It’s worth a million dollars, and it doesn’t cost a cent.
继续微笑吧！谁都懂得它意味着什么。它价值连城却不花一文。
