We’ve known that sitting for long periods of time every day has countless health consequences, like a higher risk of heart disease. But now a new study has found that sitting is also bad for your brain.
A study published last week, conducted by Dr. Prabha Siddarth at the University of California, showed that sedentary(久坐的)behavior is associated with reduced thickness of the medial temporal lobe(中颞叶), a brain area that is critical to learning and memory.
The researchers asked a group of 35 healthy people, ages 45 to 70, about their activity levels and the average number of hours each day spent sitting and then scanned their brains. They found that the subjects who reported sitting for longer periods had the thinnest medial temporal lobes. It means that the more time you spend in a chair the worse it is for your brain health, resulting in possible damage to learning and memory.
What is also interesting is that this study did not find a significant association between the level of physical activity and thickness of this brain area, suggesting that exercise, even severe exercise, may not be enough to protect you from the harmful effects of sitting.
It then surprisingly turned out that you don’t even have to move much to enhance cognition(认知); just standing will do the trick. For example, two groups of subjects were asked to complete a test while either sitting or standing. Participants are presented with conflicting stimuli(刺激), like the word “green” in blue ink, and asked to name the color. Subjects thinking on their feet beat those who sat by a 3-milicond margin.
The cognitive effects of severe physical exercise are well known. But the possibility that standing more and sitting less improves brain health could lower the bar for everyone.
I know, this all runs counter to received ideas about deep thought, from our grade school teachers, who told us to sit down and focus, to Rodin’s famous “Thinker,” seated with chin on hand.
They were wrong. You can now all stand up.
1.What can we infer from Paragraphs 3 and 4?
A.Severe exercise can lessen the damage of sitting.
B.Severe exercise can greatly improve our brain health.
C.Sedentary behavior will possibly damage our brain.
D.Brain health has nothing to do with sedentary behavior.
2.What does the underlined word “margin” in Paragraph 5 mean?
A.blank. B.edge.
C.decrease. D.difference.
3.What is the received idea about deep thought?
A.Sitting more is good for our mental health.
B.Sitting is better when we think.
C.Exercise more can improve our cognition.
D.We should stand while thinking.
4.The passage mainly tells us ________.
A.people tend to sit while thinking
B.standing more can make our brain healthier
C.physical exercise can improve our brain health
D.sedentary behavior leads to countless health problems

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.
1.The Stir Kinetic Desk has been designed to_______.
A.help users with their work
B.keep users moving all the time
C.get users to exercise while working
D.remind users of their working schedule
2.Which is the feature of the touchscreen of the desk?
A.It can tell users when to change positions.
B.It can track users’changes of positions.
C.It can keep users in a fixed position.
D.It can detect users’health condition.
3.Which of the following can best describe the desk?
A.Productive but challenging.
B.Convenient but unaffordable.
C.Complex and impractical.
D.Multi-functional and intelligent.
4.What does the author intend to tell us in the last paragraph?
A.To spend money on such a desk is rewarding.
B.We should get such a desk as soon as possible.
C.It won’t be long before the desk is widely used.
D.Desks play a very important role in our daily life.
