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),Flixborough (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.all 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.

分析 章大意为:先对比一些人类活动的安全性,接着列举发生在一些城市的化工事故,用数字说明那些事故造成的后果;最后文章解释发生事故的原因.

解答 31.D.细节理解题:从文章第一段可知staying at home="traveling"to work on public transport="working"at the office"all is very low.根据这句子"However,what about flying compared to working in the chemical industry?Unfortunately,the former is 65 times riskier than the latter!"可知D项正确.
32.B.细节理解题:从第二段的第一、第二句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.可知,化学工厂由于出现问题而引起死亡;故选B.
33.B.细节理解题:根据第四段第三句"The Flixborough fireball was the fault of management,which took risks to keep production going during essential repairs."可知B正确.
34.B.细节理解题:根据第四段第二句"Thus the Texas City was caused by tons of ammonium nitrate,which is safe unless stored in a great quantity."可知硝酸铵是一种不能大量存放在一起的化学物质.故B正确.
35.C.推理判断题:A 根据常理,若不对设备进行维护,会增加发生事故的可能.所以不能避免,故排除;B 官方是应该关系化工厂的生产活动的.D 文章分明已列出气体爆炸引起的事故,说明那不是总是安全的.所以C 正确.

点评 考察学生的推理判断能力和联系上下文的能力,在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.此类的填空题一定要联系上下文,根据上下文的内容加上自己的理解,再作出正确的判断.

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(弯腰驼背)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(顺时针方向地) 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(凝块)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.

16.Body image is a person's opinions,thoughts,and feelings about his or her own body and physical appearance.Having a positive body image means feeling pretty satisfied with the way you look,appreciating your body for its capabilities and accepting its imperfections.Body image is part of someone's total self-image.So how a guy feels about his body can affect how he feels about himself.
Recognize your strengths.Different physical qualities and body types are good for different things-and sometimes the things you did well as a kid can change during puberty (青春期).What does your body do well?Maybe your speed,flexibility,strength,or coordination leads you to excel at a certain sport.Or perhaps you have some non-sports skills.Just exploring talents that you feel good about can help your self-respect and how you think of yourself.
A good body doesn't always translate into athletic success.Too often,the way guys see their body image is closely associated with their performance on a sports field or in the gym.But what if you don't like team sports or you got cut from a team you really wanted to make?
If you don't like team sports,find another form of physical activity that gets you going.This will help you stay in shape and help you to appreciate the skills you may not have realized you had in a team environment.
If you like team sports but didn't make a particular team,use this as an opportunity to discover what you're good at,not to regret what you aren't best at.
Look into starting a strength training program.Exercise can help you look good and feel good about yourself.Good builds don't just happen-they take hard work,regular workouts,and a healthy diet.There's no need to work out too much.A healthy routine can be as simple as exercising 20minutes to 1hour three days a week.Another benefit of working out properly is that it can cheer up yourself--lifting weights can lift your spirits.
Don't harm your body,respect it!To help improve your view of your body,take care of it.Treating yourself well over time results in a healthier,stronger body--and that contributes to a better body image.Practicing good living habits-regular showering; taking care of your teeth,hair,and skin; wearing clean clothes,etc.--also can help you build a positive body image.
Be yourself.Your body is just one part of who you are-along with your talent for comedy,a quick wit,or all the other things that make you unique.Your talents,skills,and beliefs are just as much a part of you as the cover they come in.So try not to let minor imperfections take over.

55.The HM)st important point of body image lies in it that ijt is closely associated withD
A.one's physical appearance   B.one's athletic achievements
C.one's body abilities        D.one's self-confidence
56.Witch of die following statements is true?D
A.One's abilities developed in his childhood will stay on all one's life.
B.A good body is certain to lead to a good sport performance.
C.A good body image results mainly from extreme workouts.
D.Exploring non-sports talents matters equally as sports skills in building self-respect.
57.It can be inferred from the passage thatB
A.lifting weights is the best sport in lifting one's spirits
B.keeping good living habits does good to body image
C.one should try not to let minor imperfection take over
D.any activity out of.team sports can lead to one's discovery of one's potential skills
58.This passage mainly deals withC
A.what body image is 
B.why body image is important
C.how body image should be improved      
D.what makes up body image.
13.Archaeologists believe they are on the turning point of throwing light on the life of William Shakespeare-by excavating (发掘) what may have been the playwright's dust hole.
Experts have begun excavating the ruins of New Place,Shakespeare's former home in Stratford-upon-Avon,which was destroyed 250 years ago.Although little remains of the property,the team,led by Birmingham Archaeology,believes it has identified a dust hole used by the 16th century poet.
Small pieces of pottery (陶瓷) and broken clay pipe have already been found from a muddy hole on the site,which they claim could yield some of the most significant discoveries about Shakespeare in decades.The dig focuses on three areas of the property,which Shakespeare bought in 1597 when he returned to his home town from London having achieved fame-including the so-called knot garden at the back of the building.
Dr Diana Owen,Director of the Shakespeare Birthplace Trust,which owns the site,said,"We do not know if the knot garden was an area used by Shakespeare-it may have been a yard simply used by his servants.But this could actually yield some fantastic results,especially if it was an area where rubbish was thrown or the dust hole was located."
Kevin Colls,from Birmingham Archaeology,added,"Through documentary evidence we know Shakespeare lived at New Place but we have very little information regarding the layout (布局) of the house and gardens at this time.Through archaeological fieldwork,in particular the dig of structural remains and the recovery of artefacts,we hope to fill in the blanks."
Until October,visitors will be able to watch archaeologists and volunteers at work as they excavate the remains of the house,which was knocked down in 1759.Experts hope to unearth evidence to support theories that Shakespeare wrote many of his most famous works at the property.

71.This excavation intends toC.
A.know something about the playwright's dust hole
B.search for some treasure in the dust hole
C.explore the life of William Shakespeare
D.find something that Shakespeare lost

A.15th           B.16th           C.17th           D.18th
73.Small pieces of pottery and broken clay pipe on the siteB.
A.could show Shakespeare's luxurious life
B.could lead to important discoveries about Shakespeare
C.could show us that Shakespeare lived at New Place
D.could prove when New Place was knocked down
74.The underlined phrase"the blanks"in Paragraph 5 refers toD
A.the ruins of New Place 
B.the smallest pieces of broken pottery
C.three areas of the property 
D.the layout of the house and gardens of New Place
75.What can we learn from the text?A
A.Shakespeare used to live at New Place.
B.Shakespeare became famous after 1597.
C.Only his servants used the knot garden.
D.Dr Diana Owen owns Shakespeare's property.
