Question

阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。

We’ve been covering standing desks for a long time now because experts agree that sitting all day is killing us．We want to be productive while also keeping our bodies healthy．Over the years，there have been several solutions to this from fixed standing desks to adjustable ones，portable desks to ones that change into shelves．

However, the most high tech and elegant solution has to be this new smart desk called The Stir Kinetic Desk．The desk learns your daily behaviors and moves between a sitting and standing height regularly throughout the day to keep you moving without interrupting your work flow．

You can program specific sitting and standing intervals or let the desk set the schedule．If you tend to sit while returning emails in the morning，but always want to stand during that afternoon conference call，the desk will learn those regular habits and adjust the schedule to fit them. Of course，the desk can always be manually lowered or raised by using the touch screen on the lower left comer of the desk．

When switching positions，the desk gently dips and rises to let you know that a change is coming up．If you’re not ready to switch positions at that time，you can tap the touchscreen to stay sitting or standing for a while longer．

The built．in touchscreen also keeps track of your daily sitting and standing times and tells you how many calories you’ve burned．You can even set goals for how long or often you want to stand．The desk also works with fitness devices like the FitBit to track your movements．

All of that smart tech doesn’t come cheap though．The M1 desk，which is the everyday model，runs a steep $2，990，while the more executive model with added features，the F1，goes for$4，190．

While expensive，it’s worth thinking of how much time we spend at our desks．Much like a good mattress(床垫)，a good desk that works with you is worth the investment．Hopefully in a few years these smart，integrated desks will be more common and less expensive．
