Pushbike Danger
Low speed bicycle crashes can badly injure一or even kill一children if they fall onto the
ends of the handlebars（车把）.So a team of engineers is redesigning it to make it safer.
Kristy Arbogast,a bioengineer at the Children's Hospital of Philadelphia in
Pennsylvania,began the project with her colleagues.The cases they reviewed about
serious abdominal（腹部的）injuries in children in the past 30 years showed that more than
a third were caused by bicycle accidents."The task was to identify how the injuries occurred
and come up with some countermeasures."she says.
By interviewing the children and their parents,Arbogast and her team were able to
reconstruct many of the accidents and identified a common cause for serious injuries.They
discovered that most cases occur when children hit an obstacle at slow speed,causing
them to topple（摇摆）over. To maintain their balance the children turn the handlebars
through 90 degrees一but their momentum（冲力）forces them into the end of the
handlebars.The bike then falls over and the other end of the handlebars hits the ground,
pushing it into their abdomen（腹部）.
The solution the group came up with is a handgrip（握柄）fitted with a spring and
damping（减速）system. The spring absorbs up to 50 per cent of the forces transmitted
（传递）through the handlebars in an impact. The group hopes to commercialize the device,
which should add only a few dollars to the cost of a bike."But our task has been one of
education because up until now,bicycle manufacturers were unaware of the problem."
says Arbogast.
The advantage of the new handgrip is that
A:it can be made cheaply.
B:it reduces the impact in bicycle accidents.
C:it helps to slow down the speed of the bicycle.
D:it sells well at bicycle shops.

Energy Cycle
Do you find getting up in the morning so difficult that it's painful?This might be called laziness,but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.
During the hours when you labor through your work you may say that you're“hot”.That's true .The time of day when you feel most energetic is when your cycle of body temperature is at its peak .For some people the peak comes during the morning. For others it comes in the afternoon or evening.No one has discovered why this is so,but it leads to such familiar monologues as:“Get up,John!You'll be late for work again!”The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.
You can't change your energy cycle,but you can learn to make your life fit to it better. Habit can help,Dr. Kleitman believes. Maybe you're sleepy in the evening but you must stay up late anyway .Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day,rise before your usual hour. This won't change your cycle,but you'll get up steam and work better at your low point.
Get off to a slow start which saves your energy .Get up with a leisurely yawn and stretch.Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the trouble of searching for clean clothes by laying them out the night before .Whenever possible,do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.
You are advised to rise with a yawn and stretch because it will_______.
A: help to keep your energy for the day's work
B: help you to control your temper early in the day
C: enable you to concentrate on your routine work
D: keep your energy cycle under control all day

1 Ford's great strength was the manufacturing process一not invention.Long before he
started a car company,he was a worker,known for picking up pieces of metal and wire
and turning them into machines.He started putting cars together in 1891.Although it was
by no means the first popular automobile,the Model T showed the world just how creative
Ford was at combining technology and market.
2 The company's assembly line alone threw America's Industrial Revolution into overdrive
（高速运转）.Instead of having workers put together the entire car, Ford's friends, who
were great toolmakers from Scotland,organized teams that added parts to each Model T as
it moved down a line. By the time Ford's Highland Park plant was humming（嗡嗡作响）
along in 1914,the world's first automatic conveyor belt could turn out a car every 93 minutes.
3 The same year Henry Ford shocked the world with the$5-a-day minimum wage
scheme,the greatest contribution he had ever made.The average wage in the auto
industry then was$2.34 for a 9-hour shift.Ford not only doubled that,he also took an
hour off the workday.In those years it was unthinkable that a man could be paid that much
for doing something that didn't involve an awful lot of training or education.The Wall Street
Journal called the plan"an economic crime",and critics everywhere laughed at Ford.
4 But as the wage increased later to daily$10,it proved a critical component of Ford's

Study Helps Predict Big Mediterranean Quake
1.Scientists have found evidence that an overlooked fault in the eastern Mediterranean is likely to produce an earthquake and tsunami every 800 years as powerful as the one that destroyed Alexandria in AD 365.
2.Using radiocarbon dating techniques,simulations and computer models,the researchers recreated the ancient disaster in order to identify the responsible fault."We are saying there is probably a repeat time of 800 years for this kind of earthquake,"said Ms Beth Shaw,an earthquake scientist at the University of Cambridge,who led the study. Scientists study past earthquakes in order to deter-mine the future possibility of similar large shocks.
3.Identifying the fault for the AD 365 earthquake and tsunami is important for the tens of millions of people in the region,Ms.Shaw said.The fault close to the southwest coast of Crete last produced a big enough quake to generate a tsunami about 1300,which means the next powerful one could come in the next 100 years,she added in a telephone interview.
4.Ms.Shaw and her colleagues calculate the likely intervals by measuring the motion of either side of the fault to find how often such large earthquakes would have to occur to account for that level of motion,she said.Their computer model suggested an 8 magnitude quake on the fault would pro-duce a tsunami that floods the coastal regions of Alexandria and North Africa,the southern coast of Greece and Sicily all the way up the Adriati to Dubrovnik.This would be similar to the ancient quake in AD 365 that caused widespread destruction in much of Greece and unleashed a tsunami that flooded Alexandria and the Nile Delta likely killing tens of thousands of people,she said.

First Image-recognition Software
1. Dartmouth researchers and their colleagues have created an artificial intelligence software that uses photos to locate documents on the Internet with far greater accuracy than ever before.
2. The new system,which was tested on photos and is now being applied to videos,shows for the first time that a machine learning algorithm（运算法则）for image recognition and retrieval is accurate and efficient enough to improve large-scale document searches online. The system uses pixel（像素）data in images and potentially video-rather than just text-to locate documents. It learns to recognize the pixels associated with a search phrase by studying the results from text-based image search en-gines. The knowledge gleaned（收集）from those results can then be applied to other photos without tags or captions（图片说明）,making for more accurate document search results.
3. "Over the last 30 years,"says Associate Professor Lorenzo Torresani,a co-author of the stud-y,"the Web has evolved from a small collection of mostly text documents to a modern,massive, fast-growing multimedia data set,where nearly every page includes multiple pictures or videos. When a person looks at a Web page, he immediately gets the gist（主旨）of it by looking at the pictures in it.Yet,surprisingly,all existing popular search engines,such as Google or Bing, strip away the information contained in the photos and use exclusively the text of Web pages to perform the document retrieval. Our study is the first to show that modern machine vision systems are accurate and efficient enough to make effective use of the information contained in image pix- els to improve document search."
4. The researchers designed and tested a machine vision system-a type of artificial intelligence that allows computers to learn without being explicitly programmed-that extracts semantic（语义的）information from the pixels of photos in Web pages. This information is used to enrich the description of the HTML page used by search engines for document retrieval.The researchers test-ed their approach using more than 600 search queries（查询）on a database of 50 million Web pages. They selected the text-retrieval search engine with the best performance and modified it to make use of the additional semantic information extracted by their method from the pictures of the Web pages.They found that this produced a 30 percent improvement in precision over the original search engine purely based on text.
The new system was found more effective in document search than the______.
A: using photos
B: description of the HTML page
C: current popular search engines
D: document search
E: information in images

Energy and Public Lands
The United States boasts substantial energy resources. Federal lands provide a good deal of US energy production,the US Department of the Interior manages federal energy leasing （租赁）both on land and on the offshore Outer Continental Shelf Production from these sources amounts to nearly 30 percent of total annual US energy production.
In 2000,32 percent of US oil,35 percent of natural gas,and 37 percent of coal were pro-duced from federal lands,representing 20,000 producing oil and gas leases and 135 producing coal leases. Federal lands are also estimated to contain approximately 68 percent of all undis-covered US oil reserves and 74 percent of undiscovered natural gas.
Revenues from federal oil,gas,and coal leasing provide significant returns to US taxpayers as well as State Government. In 1999,for example,$553 million in oil and gas revenues were paid to the US Treasury,and non-India coal leases accounted for over$304 million in revenues,of which 50 percent were paid to State governments. Public lands also play a critical role in energy delivery. Each year , federal land managers authorize（许可）rights of way for transmission lines , rail systems , pipe-lines,and other facilities related to energy production and use.
Alternative energy production from federal lands falls behind conventional energy pro-duction , though the amount is still significant. For example , federal geothermal（地热）re-sources produce about 7. 5 billion kilowatt-hours（千瓦时）of electricity per year,47 percent of all electricity generated from US geothermal energy. There are 2,960 wind turbines on public lands in California alone,producing electricity for about 300,000 people. Federal hydropower （水电）facilities produce about 17 percent of all hydropower produced in the United States.
Because of the growing US thirst for energy and increasing public unease with depend-ence on foreign off sources,pressure on public lands to meet US energy demand is becoming more intense. Public lands are available for energy development only after they have been evaluated through the land use planning process.If development of energy resources conflicts with management or use of other resources,development restrictions or impact moderation measures may be enforced,or mineral be banned altogether.
Geothermal resources,wind turbines,and hydropower facilities in Paragraph 4 are ci-ted as examples to illustrate that______.
A: alternative energy production is no less than conventional energy production
B: they are the most typical conventional energy resources from public lands
C: geothermal resources are more important than the other two
D: the amount of alternative energy production from public lands is huge

There are 2,960 wind turbines on public lands in California alone,producing electricity for about 300,000 people. Federal hydropower （水电）facilities produce about 17 percent of all hydropower produced in the United States.
Because of the growing US thirst for energy and increasing public unease with depend-ence on foreign off sources,pressure on public lands to meet US energy demand is becoming more intense. Public lands are available for energy development only after they have been evaluated through the land use planning process.If development of energy resources conflicts with management or use of other resources,development restrictions or impact moderation measures may be enforced,or mineral be banned altogether.
Geothermal resources,wind turbines,and hydropower facilities in Paragraph 4 are ci-ted as examples to illustrate that______.
A: alternative energy production is no less than conventional energy production
B: they are the most typical conventional energy resources from public lands
C: geothermal resources are more important than the other two
D: the amount of alternative energy production from public lands is huge

Energy and Public Lands
The United States boasts substantial energy resources.Federal lands provide a good deal of US energy
production,the US Department of the Interior manages federal energy leasing（租赁）,both on land and on
the offshore Outer Continental Shelf. Production from these sources amounts to nearly 30 percent of total
annual US energy production.
In 2000,32 percent of US oil,35 percent of natural gas,and 37 percent of coal were produced from
federal lands,representing 20,000 producing oil and gas leases and 135 producing coal leases.Federal lands
are also estimated to contain approximately 68 percent of all undiscovered US oil reserves and 74 percent of
undiscovered natural gas.
Revenues from federal oil,gas,and coal leasing provide significant returns to US taxpayers as well as
State Government.In 1999,for example,$553 million in oil and gas revenues were paid to the US Treasury,
and non-Indian coal leases accounted for over $304 million in revenues,of which 50 percent were paid to
State governments.Public lands also play a critical role in energy delivery.Each year,federal land managers
authorize rights of way for transmission lines,rail systems,pipelines,and other facilities related to energy
production and use.
Alternative energy production from federal lands falls behind conventional energy production,though the
amount is still significant. For example , federal geothermal（地热）resources produce about 7. 5 billion
kilowatt-hours（千瓦时）of electricity per year , 47 percent of all electricity generated from US geothermal
energy.There are 2,960 wind turbines on public lands in California alone,producing electricity for about
300 ,000 people. Federal hydropower（水电）facilities produce about 17 percent of all hydropower produced

Because of the growing US thirst for energy and increasing public unease with dependence on foreign oil

If development of energy resources conflicts with management or use of other resources,development restric-
tions or impact moderation measures may be enforced,or mineral production may be banned altogether.
What is the main idea of this passage?
A:Public lands play an important role in energy production.
B:Public lands are one of the main sources of revenues.
C:Public lands should be developed to ease energy shortage.
D:Public lands store huge energy resources for further development.
