We open the front door and there's not a speck of dust in there.

我们打开前门，一尘不染。

There’s not a speck of dust in the kitchen.

【dust】厨房里一尘不染。

" Not a speck of him. Oh, Cap'n, what do you s'pose has become of him" ?

“他一点儿也不像。哦，船长，你猜他怎么样了” ？

This is the most perfect of them all; not a speck of blight or mildew in it.

这是其中最完美的； 里面没有一丝枯萎或霉变。

Not a speck escaped Aunt March's eye, and all the furniture had claw legs and much carving, which was never dusted to suit.

没有一点灰尘能逃过马奇叔婆的眼睛。而且所有的家具都有爪脚，还有许多雕刻，以致清扫工作很难令人满意。
