lie in ruins 变成废墟,是个动作 wait to be taken apart也是个动作
(通读整个句子,发现两个动作是并列的关系,并且找到了关键的“,”和“ing”)
句子中,【There on the shore 状语】
这个句子的句型结构是 you can see + 宾语从句
a steam powered ship lie in ruins and wait to be taken apart是这个宾语从句【covered with dirt是a steam powered ship的修饰语,在此忽略】
句型运用 Someone do ... and do ...可以变成Someone do ... , doing ...
第二个动作变成V-ing的形式,做这个句子的伴随状语,表这两个动作的同时进行.
所以这个句子应该是
There on the shore you can see a steam powered ship covered with dirt lie in ruins , waiting to be taken apart.
当然在心里你可以默念
There on the shore you can see a steam powered ship covered with dirt lie in ruins and wait to be taken apart.
Recently, a solar-powered (太阳能动力的) plane took to the sky for
Recently, a solar-powered (太阳能动力的) plane took to the sky for the first time. It passed an important test on the way to travel around the world.

The plane took off from an airport in Switzerland. It slowly rose above the fields and into the sky.
“There has never been an airplane of that kind that could fly — never an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project.
During the 90-minute flight(飞行), the plane did several turns. It climbed nearly 1.6km above the countryside.
Engineers plan to test a night flight before July. Then they will use the results of the tests to build a second plane. They plan to travel around the world in that plane in 2012.
“We want to fly it day and night with no fuel (燃料),” Piccard said.
Piccard and pilot(飞行员) Andre Borschberg will take the plane around the world. They will make a few stops to change places and rest after a long time in the air — and to show off their airplane.
The plane will fly at 70 km per hour on average(平均). That is faster than a bike and slower than a car. The pilots will keep the plane in the air for up to five days at a time.
小题1:The passage is probably taken from _____________.
A.a postcard B.a newspaper C.a comic book D.an advertisement
小题2:The solar-powered plane ________________.
A.is big and heavy B.uses much energy
C.passed the first test D.will have a night flight after July
小题3:How long will it take the solar-powered plane to travel 140 km?
A.About a day and a night. B.About 5 days.
C.About 2 hours. D.About 90 minutes.
小题4:Which of the following is NOT mentioned(提到)in the passage?
A.During the 90-minute flight, the solar-powered plane reached a height of 1.6km.
B.The solar-powered plane is slower than a car and faster than a bike.
C.Maybe the solar-powered plane will fly with no fuel.
D.It took a long time to build the solar-powered plane.
小题5:The passage mainly talks about ___________________.
A.the solar-powered plane
B.the speed of the solar-powered plane
C.how to make the solar-powered plane
D.the world travel of the solar-powered plane

英语翻译
Is there a chocolate-powered racing car in the world?Hey,you've read too many children's books!But wait!Now there is really such a racing car in the world.A team from a British university made it.
The chocolate-powered racing car's engine uses waste from chocolate factories or vegetable oil as fuel.Its body is made from potatoes,its steering wheel is made from carrots,its seat is made of soybeans,and its brake pads are made from nuts!Well,can this car run very fast?Certainly!It can go from zero to 60 miles per hour in 2.5 seconds,and go as fast as 135 miles per hour.When the racing car is running,it cleans itself and lets out oxygen.
"It tooks us more than nine months to complete the racing car," said a team number."The car is really green.You can find many of the car's parts at a farmer's market,or even in a litter bin because most of the materials are waste in most people's eyes.It's fun."
However,this eco-friendly car cannot be driven in the offical race because of the engine's unusual fuel.

世界上有以巧克力为动力的赛车吗?嘿,你读太多童话书了吧!但是,等下~现在世界上真的有这样一种赛车,一个来自英国大学的团队制造了它.
这种巧克力动力赛车的发动机以巧克力厂的废物或蔬菜油为燃料.它的机身使用西红柿做成的,齿轮是由胡萝卜制成的,座椅则是由大豆制成,而刹车垫则是使用坚果制成.那么这辆车能快速运转吗?当然,它的速度可以在2.5秒内从零提升到60米每小时,而且平均时速135米每小时.当这辆赛车运行的时候,它能够自我清洁并且排出氧气.
“我们花费了九个多月的时间才完成它”制作团队中的一员说.“这辆车是纯绿色的,你可以在任意一家农产品市场或者小的售货店买到这辆车所使用的零件,因为这辆车使用的零件都是大多数人严重的废物,这很可笑.”
但是,由于发动机燃料的非常规性,这辆经济适用车还不能参加官方比赛.

我们一步步地进行分析:
第一个合成词里面power作名次解释的时候表示能源、动力.在这里power词性发生变化,用作动词,表示提供能源或者是说提供动力.hydrogen-powered 相当于×× is powered by hydrogen,因此在这里是表示被动,使用power的过去分词.
至于第二个合成词hydrogen-burning,动词的现在分词表示主动,相当于×× burns hydrogen.

请问下面的英语怎么翻译
Powered by two hybrid diesel-electric engines, TaxiBot reduces the amount of fuel used in taxi operations by 85 per cent. For example, the average taxiing-time in Frankfurt is 10 to 12 minutes. The net saving generated by using TaxiBot to tow a Boeing 737 to a disconnecting point close to the runway is 35 gallons of jet fuel, which cost more than $100 at today’s prices. For an Airbus A380 superjumbo jet on a 10-minute taxi, TaxiBot will cut 95% of the fuel burn, generating a net saving for each departure of 130 gallons of jet fuel costing nearly $400.
Totally in line with TLD’s Green philosophy,TaxiBot is the perfect combination of the ecological and economic interests of its users. TaxiBot solves the two main problems encountered in dispatch towing applications:
• The liability issue of the pilot versus driver liability during taxiing; this is a key requirement of the application because once passengers are onboard, the pilot is fully responsible for the aircraft.
• Nose landing gear fatigue; in addition to ensuring that the system is under pilot control, there is also a major concern about the stress applied during traction and braking, not only to the nose landing gear but also to the front fuselage.

TaxiBot解决两个主要问题在牵引应用中所遇到的调度:•责任问题的试点与司机的责任在滑行;这是应用程序的一个关键要求是因为一旦乘客在船上,飞行员是完全负责的飞机.
•责任问题的试点与司机的责任在滑行;这是应用程序的一个关键要求是因为一旦乘客在船上,飞行员是完全负责的飞机.

A solar-powered(太阳能动力的) plane has passed an important test on the way to travel around the world. The plane took off from an airport in Switzerland at 45km an hour. it slowly rose above the fields and into the sky. During the 90-minute flight, the plane did several turns. It climbed nearly 1.6km above the countryside.
“There has never been an airplane of that kind that could fly – never an airplane so big, so light, using so little energy,” said Bertrand Piccard, a leader of the project.
Engineers plan to test a night light soon. They plan to travel around the world in that plane in 2012. “We want to fly it day and night without fuel,” Piccard said.
Piccard and pilot Andre Borschberg will take the plane around the world. They will make a few stops to change places and rest after a long time in the air – and to show off their aircraft.
The plane flies at 70 kilometers per hour on average. That is faster than a bike. The pilots will keep the plane in the air for up to five days at a time.

Solar-powered 'supertrees' breathe life into Singapore's urban oasis
Singapore's latest development will finally blossom later this month,with
an imposing canopy(天蓬,遮篷) of artificial trees up to 50 meters high towering over a vast urban
oasis.
The colossal solar-powered supertrees are found in the Bay South garden,
which opens to the public on June 29.It is part of a 250-acre(英亩) landscaping project -- Gardens by the
Bay -- that is an initiative from Singapore's National Parks Board
that will see the cultivation of flora and fauna from foreign lands.
The man-made mechanical forest consists of 18 supertrees that act as
vertical gardens,generating solar power,acting as air venting ducts(管道) for nearby conservatories,and collecting rainwater.To
generate electricity,11 of the supertrees are fitted with solar photovoltaic
systems that convert sunlight into energy,which provides lighting and aids
water technology within the conservatories below.

Varying in height between 25 and 50 meters,each supertree features
tropical flowers and various ferns(蕨类植物) climbing across its steel framework.The large canopies
also operate as temperature moderators,absorbing and dispersing heat,as well
as providing shelter from the hot temperatures of Singapore's climate to visitors
walking beneath.
The project is part of a redevelopment scheme(计划,方案) to create a new downtown district in the Marina Bay(滨海湾) area,on Singapore's south side.Project organizers hope
the completed Gardens by the Bay will become an eco-tourist destination
showcasing sustainable practices and plants from across the globe.
Bridges dubbed(命名)
"skywalks" have been erected(建造) connecting several of the higher 50-meter supertrees
(the same height as the Arc de Triomphe(凯旋门) in Paris),letting visitors stroll between them and view
the gardens from dizzying heights.
The horticultural heaven also boasts two green conservatories in close
proximity -- the Cloud Forest(雾林) and Flower Dome(屋顶) -- climate-controlled biomes(生物群系) inspired by the shape of an orchid flower,which project
organizers hope will become the park's main attractions.The biomes are the
equivalent size of four football fields and will become the new home for
220,000 plants from almost every continent.These are some of the only areas
where an admission fee is charged -- approximately US$22 (S$28) for
holiday-makers or US$16 (S$20) for Singapore residents.
还有一段:
However,the supertrees and biomes only make up 5% of the multimillion-dollar landscaping development won after an international design competition by UK landscape architects Grant Associates(英国景观建筑联营公司).The remainder of the Bay South garden will pay homage to the ethnic makeup of the country.In the Heritage Gardens,visitors can explore the Chinese,Malay,Indian and Colonial-themed areas and learn about the links between plants and Singapore's history.Surrounding these cultural green spaces in the rest of the 103-acre(英亩) Bay South park are sprawling areas complete with lakes and bridges.

有可能是指“多点供电/多电源供电”.

如果它是交流电供给的,230伏的CE标准就可以了,不必满足RoHS标准.
