Tears were welling up in her eyes.

她热泪盈眶。

Droplets of sweat were welling up on his forehead.

一颗颗小汗珠从他额头上不断冒出来。

With tears welling up in my eyes, I rushed out of the flat and ran along the street.

我泪流满面地冲出了公寓，沿着街道跑。

Welling and swelling I bear in the tide.

在潮汐中孕育喷涌的泉源汹涌的浪花。

"I don't know," Tess replied with her eyes welling up.

“我不知道”，苔丝含着眼泪回答说。
