Bamboo is one of the world's most useful plants.For thousands of years,bamboo has been used in many different ways from food to medicine to clothing and in small ways as a building material.
However,bamboo is not often used as a building material in the developed world.A professor at the University of Pittsburgh is trying to change that.The professor and his students are testing the strength of bamboo.They are testing how much pressure or weight it can take before breaking.Kent Harries is a professor at the University of Pittsburgh.Harries says that testing methods for bamboo need to be the same for all.They need to be standardized.Standardizing test methods for bamboo will help to bring the plant into common use.It will also give engineers and builders around the world a dependable standard.
Harries says bamboo is strong in nature.The strength of at least three species of bamboo is similar to steel.Besides its strength,bamboo has other features that make it very useful in building.He says it i s resilient(有彈性的),meaning it keeps its shape and strength even under pressure.
Bamboo also grows quickly.Bamboo that is suitable for construction needs much less resources than wood.The harvest cycle of bamboo is about 3 years.Softwoods such as cedar,pine and spruce have a harvest cycle of about 10 years.And hardwoods that come from flowering plants such as oak and walnut need more than 30 years.
Bamboo is widely used as food for pandas.It is also used for flooring and window covers.However,for building,bamboo is not used much outside is native growing area.This is mostly because of its round shape.But there are other reasons too.People think that bamboo is a low quality building material.

1.閱讀下面短文,根據其內容寫一篇60詞左右的內容概要。
What time do you start work?Do you prefer a leisurely start to the day,or are you an early bird who likes to get going at the crack of dawn?
At one computer programming company in the US you have no such choice.Work begins at the same oddly specific time every day-9:06 am.
In contrast to a more conventional 9 am kick-off,employees in Pivotal Software's 20 offices around the globe have to be at work and ready to go precisely six minutes later.
At that time a cowbell is rung and employees gather for a brief stand-up meeting.After that it's a long time to work,with no other meetings or distractions throughout the working day.They focus on working until 6 pm sharp,at which point everybody stops working.
So what's the reason behind this unique timekeeping?Company CEO Rob Mee explains it's about making his team of computer programmers as efficient as possible.
"I realized that programmers,if left to their own devices,may roll in at 10 am," he says.
"We thought that if we made it 9 am,developers prepare themselves for the day would think,'Well if it is 9 am I'll be late.'"
He needed a little more extra time,but a starting time of 9:05 am felt too rigidly precise-whereas 9:06 am seemed "fun".
Mr Mee was also thinking of their stomachs.Lazier programmers who turned up around 10:00 am would also often have missed breakfast.This meant they would be hungry by 11:00 am and take an early lunch,leaving them with an endlessly long working afternoon ahead.So he decided to provide breakfast as an extra incentive(激勵)to get in to the office on time.
The company's approach to punctuality may seem boring,but Pivotal Software is in fact a highly successful company,valued at 20 billion RMB.And Pivotal is not alone:Silicon Valley has long been associated with an alternative working culture.Google has "nap pods" and meditation classes,while Netflix offers a year's paid parental leave(親子假).發(fā)布:2024/12/10 2:0:1組卷:2引用:1難度:0.6 -

The World Rice Conference has voted Cambodian rice the best rice in the world.Cambodia produced just one percent of the world's rice.It is trying to increase that amount,and the award may help.
The country's rice industry is small and not well-organized.As a result,large amounts of unprocessed rice are sent to Thailand and Vietnam where it is sold for a higher price.But rice means a lot to Cambodia's economy.Many Cambodians survive in part by growing rice on small pieces of land.
Sok Puthyvuth is the president of Cambodia Rice Federation. "We need better seeds,we need a better collection process,we need better storage,we need better logistics(物流),and also our export needs to brand Cambodian rice to be one of the top brands in the world." Keat Chhon is Cambodia's former deputy prime minister.He says increasing rice export will improve the lives of many of the country's farmers.He says the purpose of the rice policy is to reduce poverty and help people in rural areas earn more.This is highly beneficial to making the development gap between rural and urban areas in Cambodia smaller.
But exporter David Van says the country's rice industry continues to suffer from the same problems it has had for many years.He says these include the high cost of electricity and a lack of good seeds.And he says the country's rice industry needs to change the way it markets its product to show it is different from what other countries offer. "You need to differentiate your product from that of your competitor next door.Otherwise,your product will continue being compared automatically to what the next-door competitor is offering." Cambodia faces other problems as well.Countries like Myanmar also want to increase their rice export.And,Thailand has extra rice,which is forcing down prices.發(fā)布:2024/12/10 23:0:1組卷:4引用:1難度:0.3 -
3.閱讀下面短文,根據其內容寫一篇60詞左右的內容概要。
Speed is very important in avalanche (雪崩)rescues.There will be narrow chances to escape if a skier is buried for 30 minutes or more.Now that 30 minutes can mean the difference between life and death for a skier lost on a snowy mountain,most people would depend on lifesaving dogs.
Noble works as a rescue team member in a vacation land,California.He tells us,"Dogs run fastest when an accident happens." His partner Wylee,a lifesaving dog,can search an accident scene the size of a football field.It only needs 5 to 10 minutes.However,5 rescue team members have to spend a couple of hours in the same area.
Apart from its excellent speed,Noble chooses Wylee as his partner partly because it weighs only about half what other kinds of dogs weigh.Rescue team members have to carry their dogs to search sites in addition to carrying 60 pound backpacks with food,water and other equipment.The dogs need the lift so that don't get tired before they start working.
There aren't adequate data on how often dogs take part in avalanche searches or how often they are able to help local people in danger.But the dogs don't save that many people.That's because there aren't that many to save.A quarter of people in danger die from serious injuries before the snow stops moving.Of those buried who weren't killed by injuries,half die within 20 minutes.If there is a chance of rescue,though,the dogs also cut search time for the remains.
Erica Mueller,a famous director,wanted to see how the lifesaving dogs worked,so she volunteered to spend part of an hour in a roomy snow cave waiting to be found.She was armed with a radio and was wearing several layers to stay warm.After being rescued by Wylee,she said,"I can't talk like a survivor,but it was definitely a cool way to see how well trained those dogs are."發(fā)布:2024/12/18 5:30:1組卷:6引用:2難度:0.4
