举一反三
The council want people to know that everyone who feeds the pigeons makes the streets crowded (拥挤)with these birds. They hope to encourage the birds to move away from the city centre and into parks and open spaces.
Ten robotic birds have been brought into the city centre to scare the pigeons away and visitors are asked not to give the pigeons any food. The mechanical birds—known as ‘robops’—will sit on the roofs of buildings. They can be moved around to different places. They look like a peregrine falcon, which is a bird that kills pigeons. They even make noises and flap their wings to scare the pigeons. They hope that the pigeons will go away before the city becomes the European Capital of Culture in two years.

You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays (喷) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (树脂)and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair --- the smoother and finer the object will be.
This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was hardly affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now they cost only about £ 1,000, according to the BBC.
Taken out of the factory and introduced to more diverse and common uses, 3-D printing can create just about anything you can think of ---flutes (笛子), bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3-D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3-D printing becomes more common, it may bring about certain problems --- such as piracy(盗版). "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun?
小题1:According to the article, in the future, the 3-D printing technology will ___.
| A．enable people to make better purchases online |
| B．be applied as widely in our daily lives as computers |
| C．change the way we make many products |
| D．shorten the time it takes for people to get what they buy online |
| A．The 3-D printing technology was taken out ofthe factory. |
| B．The 3-D printer became more affordable forconsumers. |
| C．The 3-D printer was used for medical treatmentfor the first time. |
| D．3-D printing technology began to be used invarious fields. |
| A．By analyzing a cause and an effect. | B．By making comparisons. |
| C．By giving examples. | D．By presenting research findings. |
| A．Printing out everything | B．Technology in the future |
| C．Online shopping disappearing | D．Great demand for 3-D printers |
It started when l became a junior, when college came into view. It"s the first big step to making your life your own. So when Jobs discussed his life as a student, some fears were eased. He, too, felt the need to attend college to make something of himself. He faced what many are extremely afraid of: uncertainty. His lack of understanding caused him to stop attending college and focus on what he felt was important. His story had a happy ending, of course, since he certainly turned out well.
This doesn"t mean that students shouldn"t attend college, but rather that they shouldn"t worry so much. You"ll get where you need to go, even if your path is a bit morewinding(蜿蜒的)than you"d like.
Jobs talked about the hardships in his work. His love of his work helped him carry on and he got where he was meant to be, which restates the point: don"t panic.One particular part of his speech stayed with me. Steve Jobs quoted(引用)thc saying"Stay hungry, stay foolisll" and it has become my motto. Staying foolish is realizing thatyou are still a fool, no matter how much you"ve learned or experienced. There is always more to explore. Staying hungry is wanting to find those things about which you are still uneducated.
Steve Jobs" level of success is possible to achieve, and I aim to prove that. With the will power to go into the world living every day like it"s my last and allowing the future to take care of itself, I will do great things. In the last moments of my life, I"ll be proud of what I have done and hope to have all the wisdom a person could wish for.

Now, scientists say the microbes that live on our hands could be used in a surprising way: fighting crime.
When police visit the scene of a crime, they often look for fingerprints to try to identifythe criminal. But according to a recent study, investigators could even use microbes to help break a criminal case.
Every person has his or her own set of microbes that live on their hands, according to scientists at,the University of:Colorado. That means the mix of different kinds of microbes on everybody"s hand is unique-much like one"s fingerprint.
The scientists wanted to know whether this microbe mix could be used as a new kind of fingerprint-especially in a crime scene where fingerprints might be hard to find. And policemen use forensics such as studying fingerprints to identify the criminal.
"Microbe fingerprints are harder to hide," said Noah Fierer, one of the scientists.
"You can"t sterilize(为……杀菌) a surface just by wiping it off. "
His team compared the bacteria on the hands of 273 people with the bacteria found on each person"s computer keyboard. For the study, the keyboards had been used only by the people who were being tested. The study showed that the mix of microbes from each per- son"s hands matched the mix of microbes on that person"s keyboard. The scientists were easily able to tell the 273 people apart-just by looking at their keyboards.
But there are a lot more than 273 criminals. Other scientists wonder whetherthe microbe fingerprint can really be that useful.
Fierer agrees that scientists have a lot more work to do before the microbe fingerprint will be a useful tool．

| B．They could tell who had used which computer. |
| C．Computer keyboards couldn"t keep people"s microbe fingerprints. |
| D．People"s characters could be identified by the keyboards they used. |
| A．your microbes may give you away |
| B．scientists will come to a clear conclusion soon |

The book is a comprehensive survey of structures and forms, written in clear modern English and illustrated with numerous examples. Areas of particular difficulty have been given special attention. Differences between conversational usage and strict grammatical forms are shown but the emphasis is on controversial forms.
In the fourth edition the main changes are as follows.
1. Explanation and examples have been brought up to date.
2. There is now more information on countable and uncountable nouns, attributive and predicative adjectives, adverbs of place, sentence adverbs, cleft sentences, prepositions, conjunctives, modal verbs, perfect tenses, infinitive constructions, the passive, purpose clauses and nouns.
3. Some material has been rearranged to make comparisons easier. For example, parts of chapters on can, may, must etc. are now grouped by functions; verbs of liking and preference have a chapter to themselves; suggestions and invitations have joined the chapter on commands, requests and advice.
4. The contents list now summaries every edition heading, and there is a new index containing many more entries references.
In this edition the sign “~” is frequently used to show a change of speaker in examples of dialogue. Note also that although the sign “="”" sometimes connects two words or expressions with the same meaning, it is often used more freely, e.g. to indicate a transformation from active to passive or direct to indirect speech.
We wish to thank all at Oxford University Press who have assisted in the preparation of the fourth edition. We would also like to thank Professor Egawa of Nihon University, Japan, Professor Rene Dirven of Duisburg University, West Germany and other colleagues for their friendly and helpful suggestions.
