买个好的办公桌,椅子以及电脑,让您能舒适地工作,但不要太舒服,你会松懈的。
Invest in a good desk, chair, and computer so you'll be comfortable working, but not so comfortable that you'll be tempted to slack-off.

你沉浸于手头的事,身体向办公桌和电脑前倾,双臂放在椅子的扶手上或者桌子上。
You're absorbed in whatever you're doing, leaning into your table and toward your computer, with arms placed either on the chair's armrests or on your desk.
