Wide World of Robots

Engineers who build and program robots have fascinating jobs. These researchers tinker（修补）with ma-chines in the lab and write computer software to control these devices. "They're the best toys out there," says Howie Choset at Carnegic Mellon University in Pittsburgh. Choset is a roboticist,a person who dcsigns,builds or programs robots.

When Choset was a kid,he was interested in anything that moved cars, trains,

animals. He put motors on Tinkertoy cars to make them move. Later,in high school,he built mobile robots similar to small cars.

Hoping to continue working on robots,he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena,Choset's labmates were working on something even cooler than remotely controlled cars: robotic snakes. Some robots can move only forward,backward,left and right. But snakes can twist（扭曲）in many directions and travel over a lot of different types of terrain（地形）."Snakes are far more interesting than the cars," Choset concluded.

After he started working at Carnegie Mellon,Choset and his colleagues there began developing

their own snake robots. Choset's team programmed robots to perform the same movements as real

snakes,such as sliding and inching forward. The robots also moved in ways that snakes usually don't, such as rolling. Choset's snake robots could crawl（爬行）through the grass,swim in a pond and even climb a flagpole.

But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries, the doctor has to open a patient's chest,cutting through the breastbone. Recovering from these surger-ies can be very painful. What if the doctor could perform the operation by instead making a small holein the body and sending in a thin robotic snake?

Choset teamed up with Marco Zenati,a heart surgeon now at Harvard Medical School,to investi-gate the idea. Zenati practiced using the robot on a plastic model of the chest and then tested the robot ln pigs.

A company called Medrobotics in Boston is now adapting the technology to surgeries on people. Even after 15 years of working with his team's creations,"I still don't get bored of watching themotion of my robots," Choset says.

第17题：概括大意与完成句子:

Black Holes

1. Black holes can be best described as a sort of vacuum,sucking up everything in space. Scientists have discovered that black holes come from an explosion of huge stars. Stars that are near death can no longer burn due to loss of fuel9and because its temperature can no longer control the gravitational(重力的)force,hydrogen ends up putting pressure onto the star's surface until it suddenly explodes then collapses.

2. Black holes come from stars that are made of hydrogen,other gases and a few metals. When these explode it can turn into a stellar-mass（恒星质量）black hole,which can only occur if the star is large enough(should be bigger than the sun) for the explosion to break it into pieces,and the gravity starts to compact every piece into the tiniest particle. Try to see and compare:if a star that's ten times the size of the sun ends up being a black hole that's no longer than 70 kilometers,then the Earth would become a black hole that's only a fraction of an inch!

3. ()bjccts that get sucked in a black hole will always remain there,never to break free. But

re-member that black holes can only gobble up（吞噬）objects within a specific distance to it.It's possiblc for a large star near the sun to become a black hole,but the sun will continue to stay in place. Orbits（轨道）do not change because the newly formed black hole contains exactly the same amount of mass as when it was a star,only this time its mass is totally contracted that it can end up as no bigger than a state.

4. So far,astronomers have figured out that black holes exist because of Albcrt Einstein's theory

of relativity. In the end,through numerous studies,they have discovered that black holes truly exist.

Since black holes trap light and do not give off light,it is nearly impossible to detect black holes via a telescope. But astronomers continuc to study galaxies（银河系）,space and the solar system to under-stand how black holes might evolve. It is possible that black holes can exist for millions of years,and later contribute to a bigger process in galaxies,which can eventually lead to crcation of new entities.Scientists also credit black holes as helpful in learning how galaxies began to form.

第一篇Putting Plants to Work

Using the powcr of the sun is nothing new. People have had solar-powered calculators and buildings with solar panels（太阳能电池板）for decades. But plants are the real experts. They've been using sunlight as an energy source for billions of years.

Cells in the green leaves of plants work like tiny factories to convert sunlight,carbon

dioxide(二氧化碳)，and water into sugars and starches（淀粉），stored energy that the plants can use. This conversion process is called photosynthesis（光合作用）．Unfortunately,unless you' re a plant,it's difficult and expensive to convert sunlight into storable energy. That's why scientists are taking a closer look at exactly how plants do it．

Some scientists are trying to get plants,or biological cells that act like plants,to work as verysmall photosynthcsis power stations. For example,Maria Ghirardi of the National Renewable Energy Laboratory in Golden. Colo. ,is working with grecn algae（水藻）.She's trying to trick them into producing hydrogen instead of sugars when they perform photosynthesis. Once the researchers can get the algae working efficiently,the hydrogen that they produce could be used to power fuel cells in cars or to generate electricity.

The algae are grown in narrow-necked glass bottles to produce hydrogen in the lab. During photo-synthesis,plants normally make sugars or starches. "But under certain conditions,a lot of algae are able to use the sunlight energy not to store starch,but to make hydrogen. "Ghirardi says. For example, algae will produce hydrogen in an airfree environment. It's the oxygen in the air that prevents algae from making hydrogen most of the time.

Working in an airfree environment,however,is difficult.It's not a practical way to producc cheap energy. But Ghirardi and her colleagues have discovered that by removing a chemical

called sulfate(硫酸盐)from the environment that the algae grow in,they will make hydrogen instead of sugars,even when air is present.

Unfortunately,removing the sulfate also makes the algae's cells work very slowly,and not much

hydrogen is produced. Still,the researchers see this as a first step in their goal to produce hydrogcn ef-ficiently from algae. With more work,they may be able to speed the cells' activity and produce larger quantities of hydrogen.

The researchers hope that algae will one day be an easy-to-use fuel source. The organisms are

cheap to get and to feed,Ghirardi says,and they can grow almost anywhere: "You can grow them in a reactor,in a pond. You can grow them in the ocean. There's a lot of flexibility in how you can use these organisms. "

第二篇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 offshorc Outcr Continental Shelf Production from these sources amounts to ncarly 30perccnt 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,reprosenting 20,000 producing oil and gas leases and 135 producing coal lcases. Federal

lands are also estimated to contain approximately 68 percent of all undiscovered US oil reserves and 74percent 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 we repaid to State govcrnments. Public lands also play a critical role in energy delivery. Each year,federal land managers authorize (许可) rights of way for transmission lincs,

rail systems, pipelincs,and other facilities related to energy production and usc.

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 turbincs 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 thirsts for energy and increasing public unease with dependence 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 production may be banned altogcther.

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 developcd to ease energy shortage.

D. Public lands store huge encrgy resources for further development.

第三篇On the Trial of the Honey Badger

On a recent field trip to the Kalahari Desert,a team of researchers learn a lot more about honey

badgers (獾). The team employed a local wildlife expert,Kitso Khama,to help them locate and follow the badgers across the desert. Their main aim was to study the badgcrs' movements and bchavior as discreetly (谨慎地) as possible,without frightcning them away or causing them to change their natural behavior. They also planned to trap a few and study them close up before releasing them. In view of the animal's reputation,this was something that even Khama was reluctant to do.

"The problem with honey badgers is they are naturally curious animals,especially when they see something new," he says. "That,combined with their unpredictable nature,can bc a dangerous mix-ture. If they sense you have food,for example,they won't be shy about coming right up to you for something to eat. They're actually quite sociable creatures around humans,but as soon as they feel they might be in danger,they can become extremely vicious ( 凶恶的).

Fortunately this is rare.but it does happen. "

The research confirmed many things that were already known. As expected,honcy badgers ate any crea-tures they could catch and kill. Even poisonous snakcs,feared and avoided by most other animals,were not safe from them. The researchers were surprised,however,by the animal's fondness for local melons,probably be-cause of their high water content. Preciously researchers thought that the animal got all of its liquid require-ments from its prey (猎物). The team also learnt that,contrary to prcvious research findings,thc badgers occa-sionally formed loose family groups. They were also able to confirm certain results from previous research,in-cluding the fact that female badgers never socialized with each other.

Following some of the male badgers was a challenge,since they can cover large distances in a short space of time. Some hunting territories cover more than 500 square kilometers. Although,they seem happy to share these territories with other males,there are occasional fights over an important food source,and male badgers can be as aggressive towards each other as they are towards other species.

As the badgers became accustomed to the presence of people,it gave the team the chancc to get up close to them without being the subject of the animal's curiosity - or sudden aggression. The badgers' eating patterns,which had been disrupted returned,to normal. It also allowed the team to observe more closely some of the other creaturcs that form working associations with the honey badger,as these seemed to adopt the badgers' relaxed attitude when near humans.

Why did the wild life experts visit the Kalahari Desert?

A. To find where honey badgers live.

B. To catch somc honey badgers for food.

C. To observe how honey badgers behave.

D. To find c)ut why honcy badgers have a bad reputation.

The Tough Grass that Sweetens Our Lives

Sugar cane was once a wild grass that grew in New Guinea and was used by local people for roof-

ing their houses and fencing their gardens. Gradually a different variety evolved which contained su-

crose（蔗糖）and was chewed on for its sweet taste. Over time,sugar cane became a highly valuable

commercial plant,grown throughout the world. (1)

Sugar became a vital ingredient in all kinds of things,from confectionery（糖果点心）to medicine,

and,as the demand for sugar grew,the industry became larger de more profitable. (2) Many

crops withered（枯萎）and died,despite growers' attempts to save them and there were fears that the

health of the plant would continue to deteriorate.

In the 1960s,scientists working in Barbados looked for ways to make the commercial species

stronger and more able to resist disease. They experimented with breeding programmes,mixing genes

from the wild spccies of sugar cane,which tends to be tougher,with genes from the more delicate,com-

mercial type. (3) This sugar cane is not yet ready to be sold commercially,but when this

happens,it is expected to be incredibly profitable for the industry.

(4) Brazil,which produces one quarter of the world's sugar,has coordinated an interna-

tional project under Professor Paulo Arrudo of the Universidade Estaudual de Campinas in Sao Paulo.

Teams of experts have worked with him to discover more about which parts of the genetic structure of

the plant are important for the production of sugar and its overall health.

Despite all the research,however,we still do not fully understand how the gcnes function in sugar

cane. (5) This gene is particularly exciting because it makes the plant resistant to rust,a

disease which probably originated in India,but is now capable of infecting sugar cane across the world.

Scientist believe they will eventually be able to grow a plant which cannot be destroyed by rust.

A. Since the 1960s,scientists have been analysing the mysterious of the sugar cane s genetic code.

B. Unfortunately,however,the plant started to become weaker and more prone to disease.

C. The majority of the world's sugar now comes from this.particular commercial species.

D. One major gene has been identified by Dr Angellique D'Hont and her team in Montpelier, France.

E. Eventually,a commercial plant was developed which was 5 percent sweeter than before,but al-

so much stronger and less likely to die from disease.

F. Sugar cane is now much more vigorous and the supply of sugar is therefore more guaranteed.

2013年职称英语考试理工类复习笔记 一、动词 从一定意义上讲，英语语法就是动词的语法，因此，掌握动词的特性、变化、句型是学习英语语法的重中之重。为了能更好地理解下面的讲课内容，首先要搞清动词的几个基本概念。 1) be 动词和do动词：be动词也称状态动词，用于说明状态或性质，主要用于构成英语的主系表句型;do动词也称为行为动词，分及物动词和不及物动词; 2) 及物动词和不及物动词：不及物动词后面不跟宾语, 也没有被动语态; 及物动词后面一定要有宾语; 3) 双宾语(直接宾语和间接宾语)结构和复合宾语(宾语+ 宾语补足语)结构：比较下面两个句子： My mother made me a cake.(母亲给我做了块蛋糕。) My father made me a doctor. (父亲把我培养成一名医生。) 第一句是双宾语结构，即My mother made a cake for me. 第二句是复合宾语结构，其句法功能为：My father made me (to) be a doctor (I am a doctor). 说明复合宾语结构中，宾语和宾语补足语之间有"主谓关系".

4) 情态动词：must, should, ought to, can, may, need, used to 等动词称为情态动词，有三大特征：A. 不受主语人称和数的影响，如：He may go now. / May I go now? 句中may的形式不变;B. 否定时在后面加not, 如：You ought not to have cheated her. C. 与另一动词连用，中间不用+ " to ", 如上举例。 请根据上述原则，(从语法角度)说出以下那种表达方式是对的： A. She needs to see a doctor. B. She doesn't need to see a doctor. C. Does she need to see a doctor? D. She needs not see a doctor. E. She needn't see a doctor. F. She doesn't need see a doctor. G. She needs see a doctor. 从语法角度看，A、B、C、E是对的。 5) 助动词：帮助实意动词构成某种结构的词，如: He did come yesterday; I saw him in the office.(他昨天确实来了;我在办公室见到他的。——表示强调) 五个基本句型 考研网校医药网校外语网校公务员网校网络课堂网上学习建筑网校

2020年职称英语理工A概括大意真题及答案

2020年职称英语理工A概括大意真题及答案 Geothermal(地热)Energy 1.Since heat naturally moves from hotter regions to cooler ones, the heat from the earth's center flows outwards towards the surface. In this way, it transfers to the next layer of rock. If the temperature is high enough, some of this rock melts and forms magma(岩浆). The magma ascends in its turn towards the earth's surface. It often remains well below the earth's surface, creating vast areas of hot rock. In such regions, there are deep cracks, which allow rainwater to descend underground. Some of the heated rainwater travels back up to the earth's surface where it will appear as a hot spring. However, if this ascending hot water reaches a layer of impermeable(不可渗透的)rock, it remains trapped, forming a geothermal reservoir. If geothermal reservoirs are close enough to the surface, they can be reached by drilling wells. Hot water and steam shoot up the wells naturally, and can be used to produce electricity in geothermal power plants. 2.A few geothermal power plants depend on dry-stem reservoirs which produce steam but little or no water. In these cases, the steam is piped up directly to provide the power to spin a turbine generator. The first geothermal power plant, constructed at Lardarello in Italy, was of this type, and is still producing electricity today. 3.Most currently operating geothermal power plants are either "flash" steam plants or binary(双重的)plants. Flash plants produce mainly hot water ranging in temperature from 300° to 700°Fahrenheit. This water is passed through one or

Is it art or is it just vandalism (野蛮行为)? Well, it's still a crime, but graffiti (涂鸦) has changed since the days of spraying your name on a wall to mark your territory. Street art has become much more sophisticated since a 17-year-old called Demetrius started spraying his "tag" , TAKI 183, all over the New York underground in 1971, and hip - hop culture was born. Hip-hop is a mixture of art, music and dancing, poetry, language and fashion. It came from young inner-city people who fell left out by their richer classmates and who were desperate to express themselves in any way they could. An experiment to control the spread of graffiti in Rochdale, Creater Manchester, has been sosuccessful that plans have been made by local street artists for an international convention in June. "We're planning to get people together from different countries like France and Cermany for a week, " says Liam, one of the organizers. The scheme started in 2000, and has attracted people of all age groups and both sexes. " We all share a commen interest and get on really well with each other. " The first site to be chosen was a subway. " Before we began, people were afraid to use the subway. We had it cleaned up and now, with all the artists hanging out down there, people are using it again. People can relate to graffiti much more now. " By providing places to display their talents legally, there has been a fall in the amount of "tagging" on people's private property. Street artists Temper developed his drawing skills at a young age. In art classes at school he was really frustrated because the Art teacher didn't spend time with him. They thought he was already very good at art and so spend more time with other students. So, at 12 years old, Temper started painting with all these guys he'd hooked up with who were about 22 years old. He looked
