9．With modern technology evolving，an increasing number of jobs involve sitting at a computer for at least 8 hours a day．This can actually cause pains and strains，known as Repetitive Strain Injuries （RSI）．The following are common complaints of people with office jobs．
Poor Posture
   Hunching over（彎腰駝背）and twisting the spine（脊柱）can ruin your posture and lead to many problems later in life．Poor posture can also make you seem shorter than you actually are．
   Ensuring you have the correct office furniture for your height is an important part of reducing back pain．Doing yoga 20 minutes every day can help improve your fitness，burn fat，and improve your posture．
Eye Strain
   Common symptoms of eye strain include dry，tired eyes，sharp pains behind them，unclear vision，and headaches．Although these symptoms are temporary，they can be very uncomfortable and make you lose concentration．
   Blink frequently to keep your eyes from going dry．Take short frequent breaks，or perform tasks which don't involve looking at your screen．Certain facial yoga sequences can really help to relax tired eyes．Try the"clock"sequence，for example．Imagine a clock in front of your eyes．With them as wide open as possible，do the sequence of the clock，starting at 12，moving to 5 past，and so on．If you repeat this twice clockwise（順時針方向地） and then twice counter-clockwise your eyes should feel refreshed．
Poor Circulation
   Sitting in the same position all day can have negative effects on your leg muscles and increase the risk of developing Deep Vein Thrombosis （DVT），which involves painful blood clots（凝塊）in the leg muscles．
   Take regular walks．Try practicing yoga sequences that target leg muscles to increase circulation in the legs and feet．
   Yoga brings with it definite mental and physical benefits．Many people see aerobic exercise as a chore，but view yoga as a pastime．When you wake up in the morning，try a few stretches to see how refreshing it feels．
64．Which is the right order for people to do facial yoga to relax their eyes？A
a．Open the eyes as wide as possible．
b．Repeat the movement clockwise．
c．Imagine a clock in front of your eyes．
d．Move your eyes from 12 to 5 past．
e．Move your eyes counter-clockwise．
A．c，a，d，b，e               
B．a(chǎn)，c，d，b，e           
C．c，a，e，d，b           
D．a(chǎn)，c，b，e，d
65．Which of the following is NOT supported by the text？C
A．Proper office furniture helps ease back strain．
B．Eye strain makes it hard for you to focus on what you're doing．
C．Having proper posture helps increase your height．
D．Sitting all day increases the risk of developing DVT．
66．The text is developed mainly byA
A．showing problems and giving solutions
