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．

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．

4．Which is safer--staying at home，traveling to work on public transport，or working in the office？Surprisingly，each of these carries the same risk，which is very low：However，what about flying compared to working in the chemical industry？Unfortunately，the former is 65times riskier than the latter!In fact，the accident rate of workers in the chemical industry is less than that of almost any of human activity，and almost as safe as staying at home．
The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby．It is this that makes chemical accidents so newsworthy．Fortunately，they are extremely rare．The most famous ones happened at Texas City （1947），F(xiàn)lixborough （1974），Seveso （1976），Pemex （1984）and Bhopal （1984）．
Some of these are always in the minds of the people even though the loss of life was small．No one died at Seveso，and only 28workers at Flixborough．The worst accident of all was Bhopal，where up to 3，000were killed．The Texas City explosion of fertilizer killed 552．The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542lives，just a month before the unfortunate event at Bhopal．
Some experts have discussed these accidents and used each accident to illustrate a particular danger．Thus the Texas City explosion was caused by tons of ammonium nitrate，which is safe unless stored in great quantity．The Flixborough fireball was the fault of management，which took risks to keep production going during essential repairs．The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep．When the poisonous gas drifted over the town，local leaders were incapable of taking effective action．The Pemex fire was made worse by an overloaded site in an overcrowded suburb．The fire set off a chain reaction of exploding storage tanks．Yet，by a miracle，the two largest tanks did not explode．Had these caught fire，then 3，000 strong rescue team and fire fighters would all have died．

31．Which of the following statements is TRUE？D
A．Working at the office is safer than staying at home．
B．Travelling to work on public transport is safer than working at the office．
C．Staying at home is safer than working in the chemical industry．
D．Working in the chemical industry is safer than traveling by air．
32．Chemical accidents are usually important enough to be reported as news becauseB．
A．they are very rare．
B．they often cause loss of life
C．they always occur in big cities
D．they arouse the interest of all the readers
33．According to passage，the chemical accident that caused by the fault of management happened inB．
A．Texas city  B．Flixborough  C．Seveso  D．Mexico City
34．From the passage we know that ammonium nitrate is a kind ofB．
A．natural gas，which can easily catch fire
B．fertilizer，which can't be stored in a great quantity
C．poisonous substance，which can't be used in overcrowded areas
D．fuel，which is stored in large tanks
35．From the discussion among some experts we may conclude thatC．
A．to avoid any accidents we should not repair the facilities in chemical industry
B．the local authorities should not be concerned with the production of the chemical industry
C．a(chǎn)ll these accidents could have been avoided or controlled if effective measure had been taken
D．natural gas stored in very large tanks is always safe．

14．Rice is an important part of many people's diets．Researchers from the Harvard School of Public Health in Massachusetts have released a report about rice．It shows that eating white rice increases the risk of Type Two diabetes （糖尿病）．However，eating brown rice reduces the risk of the disease．
The World Health Organization says more than two hundred and twenty million people worldwide have diabetes．Type Two diabetes results when the body cannot effectively use the sugar it produces．
    More than thirty-nine thousand men and one hundred and fifty-seven thousand women took part in the study．They were asked about their diet and day-to-day activities，as well as any pre-existing diseases．The study found that the people who ate five or more servings of white rice per week had a seventeen percent increased risk of developing Type Two diabetes．But those who ate two or more servings of brown rice a week had an eleven percent reduced risk of getting the disease．
   Brown rice is the grain in its natural form．White rice results after it has been refined．This involves removing the outer cover．Only the inner white kernel is left．White rice is often enriched to replace some nutrients lost during the refining process．
   Qi Sun is the lead writer of the report．He says the outer parts of brown rice slow down the work of the body's digestive enzymes （消化酶） into starch．This means that the release of sugar into the bloodstream is slower after eating brown rice compared to white rice．
   A diet of foods that quickly release sugar into the bloodstream has been linked with a greater risk of Type Two diabetes．The exact reason for this is not known．
   Doctor Sun says less refined grains have more nutritional value than refined grains．He says replacing white rice with whole grains like whole wheat or barley could result in a thirty-six percent lower chance of developing Type Two diabetes．He says people should replace white rice and other refined carbohydrates with whole grains whenever possible．
   However，brown rice does not last as long as white rice because of the oil-rich layer of bran．This makes it less usable in poor communities．The International Rice Research Institute is working to develop kinds of white rice whose starch is released more slowly．
63．What is the exact reason of Type Two diabetes？D
A．Eating too much white rice
B．Sugar in the bloodstream．
C．digestive enzymes in the starch
D．It is still unknown to us．
64．What does the underlined word"refined"in the fourth paragraph mean？A
A．Processed
B．Cut
C．Struck
D．Developed．
65．Which of the following is true？C
A．White rice has more nutritional value than whole grains．
B．The oil-rich layer of bran can prevent the brown rice from going bad．
C．Eating brown rice may reduce the risk of developing Type Two diabetes．
D．The outer cover of brown rice will speed the release of sugar into the bloodstream．
66．What's the best title of the passage？C
A．The importance of rice                       
B．Brown rice and white rice       
C．Diabetes and rice eating                     
D．Sugar and diabetes．

1．Federal Hocking High School in Stewart，Ohio，draws its 360students from a 270-square-mile rural area of the state's southeast corner．
In the early 1990s，teachers and students were not at all motivated．The school，says social studies teacher Deborah Burk，was sticking to the 19th-century concept of dividing the day into 42-minute periods （still common in many schools across the country），with each period counted as a credit toward graduation．Back then，Burk says，students focused more on the clock than on what she was saying．They weren't entirely to blame．The system，she felt，didn't let her do much beyond repeating the same lectures over and over：There wasn't time to challenge students to research into details．"You couldn't analyze their progress--or even think about it．"
In 1992，Dr．George H．Wood，an Ohio University education professor who'd never run a high school，was named principal．He asked students for their ideas，organized visits to programs around the country，and met frequently with staff．The result：Time passed quickly．With some arm-twisting of superintendents and state lawmakers，F(xiàn)ederal Hocking moved from the tiresome credit system to a less-is-more schedule tied to four 80-minute classes．"We decided，"Wood says，"to teach fewer things better．"In American history，for example，the emphasis changed from devoting equal time to every era to focusing on big events．
The school developed its own credit system based on important studies but added other requirements--a senior portfolio，and a yearlong project created by the students that's not always linked directly to their coursework．Project topics range from writing a world-foods cookbook to the restoration of an old tractor．Graduation based just on racking up a set number of credits was no longer possible．
Other changes followed．The seven-minute daily homeroom period--basically an attendance call--was replaced by an hour-long advisory meeting every Wednesday morning．Each teacher advises the same 14or 15kids through high school．Wood，meanwhile，never lowered his strict academic standards．"Everybody here reads Shakespeare，Emerson and Thoreau，"he says，"even kids who are going to be mechanics．"
Teacher Tim Arnold says the schedule changes had an effect similar to the flipping（彈開）of a switch："The pressure was released．Instead of looking at the clock，we could look at the students．On the first day we all went‘Wow!That was cool．'"
Between the 1995-96and 2003-04school years，the percentage of the school's ninth-graders that passed Ohio's math proficiency test rose from 50percent to 85percent．Passing grades in reading shot from 69percent to 96percent．And honors diplomas jumped from 8percent to 20percent．"We don't focus on test scores，"Wood says，"but it's clear that if you pay attention to the overall culture of the school，the test scores will rise．"
Problems of the school in the pastThe（71）division of the day into 42-minute periods
（72）Repeatingthe same teaching content again and again
No time to challenge students to（73）carryout research into details

19．Humans are among the very few animals that form a threat to elephants．Yet not all people are a danger-and elephants seem to know it．The giants have shown a remarkable ability to use sight and smell to distinguish between African racial groups that have a history of attacking them and groups that do not．Now a study shows that they can even tell these differences from words spoken in the local tongues．
Biologists Karen McComb and Graeme Shannon at the University of Sussex in Brighton，UK，guessed that African elephants might be able to listen to human speech and make use of what they heard．To find out whether this was true，they recorded the voices of men from two Kenyan racial groups calmly saying，"Look，look over there，a group of elephants is coming，"in their native languages．One of these groups was the Maasai，some of whom regularly kill elephants during fierce competition for water or cattle-grazing（放牧） space．The other was the Kamba，a crop-farming group that rarely has treated elephants violently．
The researchers played the recordings to 47elephant family groups at Amboseli National Park in Kenya and monitored the animals'behavior．The differences were remarkable．When the elephants heard the Maasai，they were much more likely to cautiously smell the air or crowd together than when they heard the Kamba．Indeed，the animals bunched together nearly twice as tightly when they heard the Maasai．
"We knew elephants could distinguish the Maasai and Kamba by their clothes and smells，but that they can also do so by their voices alone is really interesting，"says Fritz Vollrath，a zoologist at the University of Oxford，UK．
Attracted by their findings，McComb，Shannon and their colleagues wondered whether the Maasai language on its own was a danger signal，or whether the animals were responding to the combination of the language and the voice of an adult male who was likely to hold a spear．To find out，they recorded Maasai women and boys saying the same phrase，and monitored elephant-family responses to them．They found that the differences were similar to what they saw with the Kamba．

47．What is the main idea of the passage？B
A．Elephants can distinguish their enemies by sight and smell．
B．Elephants can recognize the voices of their Enemies．
C．Elephants have a remarkable ability to distinguish their enemies．
D．Elephants know that not all people are their Enemies．
48．Why did the biologists record the voices of the Maasai and the Kamba？C
A．To find out whether elephants have a good listening ability．
B．To find out the differences in voices between the Maasai and the Kamba．
C．To find out whether elephants can recognize the voices of their Enemies．
D．To find out the different characters between the Maasai and the Kamba．
49．How did the biologists come to the final conclusion in the study？A
A．By comparison．
B．By listing．
C．By discussion．
D．By argument．
50．What may be mentioned right after the last paragraph of this passage？D
A．The elephants were more likely to flee from the voices of Maasai women and boys
B．The elephants did not show any concerns about the voices of Maasai men．
C．The elephants may remain calm while hearing the voices of Maasai men．
D．The elephants were less likely to flee from the voices of Maasai women and boys．
