13.If you are sitting,please stand up.Move your legs.Touch your toes if you can.Do anything but sit.New research shows that if you cut down on the time you spend sitting,you might live longer.Sitting less than three hours a day might extend(延長) your life by two years.Cutting television time to less than two hours a day can add one point four years to life.
The human body is designed to move.The fact is just the opposite.Modern lifestyles and office jobs don't give us the chance to move around.We sit while we're eating; we sit in the car; we sit while we are watching TV.And most of us sit for many hours at work.Sitting is something we do all the time.On average,Americans sit for four and a half to five hours a day.But that does not make sitting good for us.
You may exercise often.That does not mean you can sit for the rest of your waking hours.We can't throw away physical activity.It is extremely important.Eve if you exercise for 30 minutes a day,what goes on in the other 23 and a half hours a day is also very important.
Changes are coming to some offices,especially in the design of desks.A"standing desk"lets people stand while they work.Another new design is called the"treadmill desk".It is an exercise machine that lets you walk slowly in one place.Even some U.S.schools begin to experiment with desks that are part bicycle to keep children moving.
Many companies may not buy a standing desk for everybody.However,they may get five standing desks or a treadmill desk for their employees and put them in a certain place where people can go for an hour a day to answer their emails or talk on the phone.Experts suggest some other activities:take a walk at lunchtime; walk to the offices and talk directly instead of emailing colleagues(同事).All these activities may help you live longer.
4.Why should people stand up according to the new research?D
A.They should touch their toes.
B.Standing more can cure some diseases.
C.They spend too much time watching TV.
D.Sitting less does people good and may help people live longer.
5.What can we learn about sitting?C
A.Sitting is the best position for the body.
B.The more people sit,the better they will be.
C.People usually have to sit for a long time nowadays.
D.Americans sit longer every day than people in other countries.
6.What does the underlined word"It"in Paragraph 3 refer to?A
A.Exercising.B.Sitting.C.Standing.D.The walking hour.
7.Which of the following is TRUE according to the passage?B
A.The"treadmill desk"is used by people to run.
B.The new design of desks can help people sit less.
C.It's better for school students to use standing desks.
D.It's necessary for companies to offer a sitting desk to every employees.

分析 長時(shí)間坐對人們的健康有很大的危害,而現(xiàn)代生活方式讓人們長時(shí)間坐著.為了改變這一情況,人們發(fā)明了新式的椅子,這種椅子可以讓人們站著工作,以提高人們的健康水平.

解答 4.D.細(xì)節(jié)理解題.由第一段If you cut down on the time you spend sitting,you might live longer,你坐的時(shí)間越少活得越長,本文在號召人們少坐,故選D.
5.C.細(xì)節(jié)理解題.由第二段We sit while we're eating; we sit in the car; we sit while we watch TV.Many of us sit for many hours at work.吃飯時(shí)坐著,在車?yán)镒,看電視坐著,我們工作時(shí)花費(fèi)數(shù)小時(shí)坐著,可知坐很普遍,故選C.
6.A.詞義猜測題.根據(jù)本段前兩句Though you may exercise often,that does not mean you can sit for therest of your waking hours.We can't throw away physical activity.可知即使你經(jīng)常鍛煉,也并不意味著你就可以坐很長時(shí)間.鍛煉對我們很重要,但是鍛煉之外的時(shí)間也很很重要.所以本句中的it就是指"exercising",故A項(xiàng)正確.
7.B.理解判斷題.由倒數(shù)第二段It is an exercise machine that lets you walk slowly in one place.可知這個(gè)機(jī)器會使你慢慢的走在一個(gè)地方,即減少坐的時(shí)間,故選B.

點(diǎn)評 在做閱讀理解時(shí),考生可快速閱讀短文,通讀測試題,明確考察點(diǎn),在對應(yīng)細(xì)讀,加快做題速度.有時(shí)間還可以復(fù)查校對答案.

18.Pupils remember more and behave better when 3D images are used in lessons,research suggests.They are quicker to learn and absorb new concepts,and display higher levels of concentration.
Professor Anne Bamford,of the University of the Arts,London,studied the effectiveness of 3D content in 15schools across seven countries,including the UK.Pupils in 3D classes can remember more than those in the 2D classes after four weeks,improving test scores by an average of 1 7percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D,using hand gestures and mime(模仿動作) to answer the test questions successfully.
The teachers commented that the pupils in the 3D groups had deeper understanding,increased attention span,more motivation and higher engagement in the lessons.
Children are used to 3D with the rise of computer games that use the technology-90percent of those in the study had seen a 3D film.Schools would need 3D-enabled projectors(投影儀),laptops with good picture capabilities,3D software and glasses for children to introduce animations(動作) into classrooms.
But Danny Nicholson,an educationist,said the technology would be impractical to use in
schools and could be costly.He said,"While I think the idea of 3D technology is very interesting,
I worry that 3D is a bit of an expensive gimmick(小玩意兒).There are a few cases where a true 3D image might help,but most of the time,good 2D models that can be moved would be just as effective."
In the US,one school district in Colorado is already in the process of having 1.000 3D projectors fixed in classrooms.And the University of Caledonia,which carries out scientific research into the Lake Tabon Basin  has used 3D presentations with Grade Six pupils.Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.
25.What is the main idea of the first three paragraphs?B
A.There are slight differences between 3D and 2D images.
B.Pupils perform better when 3D images are used in classes.
C.Schools have difficulties in making full use of 3D technology.
D.3D technology is always more effective than 2D technology.
26.Danny Nicholson holds the view that 3DD.
A.is of no help in classes  
B.has a bright future in classes
C.is more practical than 2D models  
D.may not be affordable for schools
27.What can we learn from the last paragraph?D
A.3D technology will replace 2D models in the future.
B.Many pupils are now more Interested In science than before.
C.Teachers will use the 3D technology through specific training.
D.3D will soon be put into use in one school district in Colorado.
28.The underlined word"engrossed"in the last paragraph meansA.
A.a(chǎn)bsorbed     B.a(chǎn)nnoyed   C.relaxed      D. confused.

2.I remember the first time that I was extremely happy.I was about 8years old when for the first time,there was a computer in the classroom.I remember that my teacher allowed each student to take turns playing various educational games on the computer.One day,I found the source code (密碼) for one of these games.Without knowing or being taught any programming language,I was able to figure out some portions of the BASIC code.
Anyone who knows a bit of programming can tell you that I just give myself an infinite(無窮大) number of lives in the game,so I can continue playing forever.This was also my first introduction to algebra (代數(shù)),and I didn't even know it at the time.This was a decisive (決定性的) moment in my life.For the first time that I can remember,I was quite happy because of what I was learning and what I was able to do.As a result,I became enthusiastic(熱情的) for the rest of my life about self-learning and computers,and I was quite happy doing them,too.
I've noticed that people who are truly content(滿意的) with life are enthusiastic in what they do.This enthusiasm,along with good health,is the key to being happy.It also leads to self-confidence and fulfillment in life,too.It may also lead to success,wealth,and achievements.
Yes,success,wealth,or achievements seem to bring some people happiness,too.Yet,I don't think they can indeed make people happy.I know plenty of people who are successful and wealthy.However,I also know several of the people with successful businesses are not happy with what they are doing.I know people who continuously buy themselves new toys,cars,computers,and televisions,yet they never seem content for too long.
Please remember that happiness comes from enthusiasm,and happiness is the journey of life,not the destination.

25.What did the writer's teacher ask the students to do on the computer?A
A.To play various educational games.
B.To figure out the BASIC code.
C.To get the knowledge of algebra.
D.To read some latest news.
26.The underlined word in Paragraph 1probably can be replaced byB.
A.danger        B.parts          C.health        D.value
27.According to the author,what can lead a person to be happy?D
A.Success and wealth.
B.Education and self-confidence.
C.Knowledge and achievements.
D.Enthusiasm and good health.
28.The author uses his own experience of being happy in order to tell usC.
A.it's very easy to learn the BASIC code
B.he has always been happy since his childhood
C.concentrating on what you love makes you happy
D.one can solve any problem in life by himself.
