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.

Mary is digging in the ground for a photo, when along comes John.Seeing that there is no one in sight, John starts to scream.John’s angry mother rushes over and drives Mary away.Once his mum has gone, John helps himself to Mary’s potato.

We’ve all experienced similar annoying tricks when we were young—the brother who stole your ball and then got you into trouble by telling your parents you had hit him.But Mary and John are not humans.They’re African baboons(狒狒).___1.__

John’s scream and his mother’s attack on Mary could have been a matter of chance, but John was later seen playing the same tricks on others.__2.__

Studying behavior like this is complicated but scientists discovered apes(猿) clearly showed that they intended to cheat and knew when they themselves had been cheated.__3.___ An ape was annoying him, so he tricked her into going away by pretending he had seen something interesting.When she found nothing, she “walked back, hit me over the head with her hand and ignored me for the rest of the day.”

Another way to decide whether an animal’s behavior is deliberate is to look for actions that are not normal for that animal.A zoo worker describes how an ape dealt with an enemy.“He slowly stole up behind the other ape, walking on tiptoe.When he got close to his enemy, he pushed him violently in the back, then ran indoors.” Wild apes do not normally walk on tiptoe.____4.__ But looking at the many cases of deliberate trickery in apes, it is impossible to explain them all as simple copying.

It seems that trickery does play an important part in ape societies.___5.__ Studying the intelligence of our closest relative could be the way to understand the development of human intelligence.

A.In most cases the animal probably doesn’t know it is cheating.

B.An amusing example of this comes from a psychologist working in Tanzania.

C.And playing tricks is as much a part of monkey behavior as it is of human behavior.

D.So the psychologists asked his colleagues if they had noticed this kind of trickery.

E.The ability of animals to cheat may be a better measure of their intelligence than their use of tools

F.This use of a third individual to achieve a goal is only one of the many tricks commonly used by baboons.

G.Of course it’s possible that it could have learnt from humans that such behavior works, without understanding why.

Rain and cold weather this summer saw honey yields from hives(巢)fall by almost three-quarters, the British Beekeepers Association(BBKA)said today. The average crop per hive was down 72% compared to last year, with just 3.6kg (81b) of honey produced compared to an annual average, the annual honey survey by the BBKA revealed.

The survey of 2,712 beekeepers in England, Northern Ireland and Wales found that 88% said this summer’s bad weather caused the descent in honey yields. The bad weather made it difficult for bees to excrete(排泄),which led to disease easily, and the bad weather also increased the risk of keeping bees for heavy rain caused the places which bees regularly visited to meet natural disasters. The bad weather also influenced the plants flowering which increased the cost of keeping bees. The BBKA issued a midsummer warning to feed bees if necessary to avoid dying from hunger. But in London, which recorded the worst results with just 2.5kg (5.61b)of honey harvested on average, beekeeping experts said that in addition to the bad weather there was a lack of food for bees in the city.

Angela Woods, secretary of the London Beekeepers Association, said, “Rather than putting beehives on office roofs, we encourage companies in London that want to help to look at different ways of supporting bees and beekeepers. We need more food for the bees and better-educated beekeepers.”

Elsewhere, the weather was the main problem. Peter Hutton, a beekeeper in Tunbridge Wells, Kent, said, “It has been the most difficult year I have known in my 53 years of beekeeping. Bad weather in spring prevented bees in many areas from collecting nectar(花蜜)from early-flowering crops such as oilseed rape(油菜),and the rain continued in many places throughout June and July, preventing honeybees from searching for food on later crops.”

The BBKA warned that as well as reducing the honey harvest, the bad weather is likely to have a longer-term influence as it will have affected the normal process of breeding for the queens, which mate(交配)on the wing on fine, still summer days. As a result they may have mated poorly and be unable to produce enough new babies to see groups through the winter.

1.According to the passage, last year the average crop per hive might be____.

A.5 kg

B.7.2 kg

C.10kg

D.13 kg

2.The underlined word “descent” means_____.

A. fall B. rise

C. disease D. variety

3.What caused the lack of food?

A. The bad weather in both autumn and winter.

B. The bad weather in both winter and spring.

C. The bad weather in both spring and summer.

D. The bad weather in both summer and autumn.

4.What does the last paragraph mainly tell us?

A. The bad weather just affects honey harvest.

B. The bad weather has effect on bees’ breeding.

C. The bad weather only has a short-term impact on bees.

D. The bad weather has effect on bees’ life in winter.

5. Which of the following statements is NOT true according to the passage?

A. The quality of the honeybees is influenced by the bad weather.

B. London companies are encouraged to take part in helping bees and beekeepers.

C. Both the cost and the risk of keeping bees are increased because of the bad weather.

D. Better-educated beekeepers are needed to improve the bad situations that the bad weather brought to bees.

Look carefully and you’ll find musicians at the top of almost any industry. The television broadcaster Paula Zahn(cello) and the NBC chief White House correspondent Chuck Todd (French horn) attended college on music scholarships; Both Microsoft’s Mr. Allen and the venture capitalist Rogar McNamee have rock bands. Lorry Page, a co-founder of Google, played saxophone in high school. The former World Bank president James D. Wolfensohn has played cello at Carnegie Hall.

The connection isn’t a coincidence. I know because I asked. I put the question to top-flight professionals in industries from tech to finance to media, all of whom had serious ( if often little-known) past lives as musicians. Almost all made a connection between their music training and their professional achievements.

Will your school music program turn your kid into a Paul Allen, the billionaire co-founder of Microsoft (guitar)? Or a Woody Allen (clarinet )? Probably not. These are outstanding achievers. But the way these and other visionaries (有远见的人) I spoke to process music is interesting.

But the key question is: why does that connection exist? Paul Allen offers an answer. He says music “establish your confidence in the ability to create.” He began playing the violin at age 7 and switched to the guitar as a teenager. Even in the early days of Microsoft, he would pick up his guitar at the end of marathon days of programming. The music was the emotional analog (类比) to his day job, both of them show his different creativity. He says, “something is pushing you to look beyond what currently exists and express yourself in a new way.”

For many of the high achievers I spoke with, music functions as a “hidden language,” as Mr. Wolfensohn calls it, one that enhances the ability to connect different or even opposite ideas. When he ran the World Band, Mr. Wolfensohn traveled to more than 100 countries, often taking in local performances (and occasionally joining in on a borrowed cello), which helped him understand “the culture of people”.

Consider the qualities these high achievers say music has sharpened : cooperation, creativity, discipline and the capacity to coordinate (协调) conflicting ideas. All are qualities obviously absent from public life. Music may not make you a genius, or rich, or even a better person. But it helps train you to think differently, to process different points of views --- and most important, to take pleasure in listening.

1.The reason why the author quote so many outstanding people as examples in the first paragraph is ___________.

A. to prove the popularity and the charm of music

B. to prove all winners are musicians before

C. to encourage kids to choose school music program

D. to prove the connection between success and music

2.Which of the following is true?

A. Everybody knows those well-known people are musicians before.

B. Musicians exist in all industries.

C. Music can certainly make you become a better person.

D.Music helps Mr. Wolfensohn have a better understanding of the different culture.

3.The author develops the passage mainly _________.

A. by classification B. by comparison

C. by example D. by process
