Speak up! No hemming and hawing, please.

有话就说，别吞吞吐吐。

Stop hemming and hawing! Tell us what’s your choice.

别总是哼哼哈哈的，你到底想要哪一个？

No more of your humming and hawing; just tell me whether you have been there.

你倒是去过那儿没有，别吞吞吐吐。

Don't stand humming and hawing, but speak out.

有话痛痛快快说出来，不要吞吞吐吐的。

Yep, instead of hemming and hawing, just grab your tennis shoes and go for a run.

对，别磨磨唧唧的了，把运动鞋抓过来去跑步吧。

But alas, I was never cool. I sat there hemming and hawing until every last molecule of oxygen had been sucked from the room.

不过我从来就没有酷过：我坐在那儿，说话吞吞吐吐，踌躇不定，只觉得大脑缺氧。
