5. Cavendish Laboratory The Cavendish Laboratory has had an important influence on biology, mainly through the application of X-ray crystallography to the study of structures of biological molecules. Francis Crick already worked in the Medical Research Council Unit, headed by Max Perutz and housed in the Cavendish Laboratory, when James Watson came from the United States and they made a breakthrough in discovering the structure of DNA. For their work while in the Cavendish Laboratory, they were jointly awarded the Nobel Prize in Physiology or Medicine in 1962, together with Maurice Wilkins of King's College London, himself a graduate of St. John's College, Cambridge. The discovery was made on 28 February 1953; the first Watson/Crick paper appeared in Nature on 25 April 1953. Sir Lawrence Bragg, the director of the Cavendish Laboratory, where Watson and Crick worked, gave a talk at Guy's Hospital Medical School in London on Thursday 14 May 1953 which resulted in an article by Ritchie Calder in the News Chronicle of London, on Friday 15 May 1953, entitled "Why You Are You. Nearer Secret of Life." The news reached readers of The New York Times the next day; Victor K. McElheny, in researching his biography, Watson and DNA: Making a Scientific Revolution, found a clipping of a six-paragraph New York Times article written from London and dated 16 May 1953 with the headline "Form of `Life Unit' in Cell Is Scanned." The article ran in an early edition and was then pulled to make space for news deemed more important. (The New York Times subsequently ran a longer article on 12 June 1953). The Cambridge University undergraduate newspaper Varsity also ran its own short article on the discovery on Saturday 30 May 1953. Bragg's original announcement of the discovery at a Solvay Conference on proteins in Belgium on 8 April 1953 went unreported by the British press. Sydney Brenner, Jack Dunitz, Dorothy Hodgkin, Leslie Orgel, and Beryl M. Oughton, were some of the first people in April 1953 to see the model of the structure of DNA, constructed by Crick and Watson; at the time they were working at the University of Oxford's Chemistry Department. All were impressed by the new DNA model, especially Brenner who subsequently worked with Crick at Cambridge in the Cavendish Laboratory and the new Laboratory of Molecular Biology. According to the late Dr. Beryl Oughton, later Rimmer, they all travelled together in two cars once Dorothy Hodgkin announced to them that they were off to Cambridge to see the model of the structure of DNA. Orgel also later worked with Crick at the Salk Institute for Biological Studies. 9. What can be inferred from the passage?

A、Bragg's announcement of the discovery on proteins went reported by the Japanese press.

B、The Cavendish Laboratory has had an important influence on biology.

C、Crick was not impressed by the new DNA model.

D、Dorothy Hodgkin was the third one to see the model of the structure of DNA.

While virtual reality systems are getting better at immersing us in a simulated experience
of reality, one UK business has developed a visually arresting yet surprisingly simple solution. Born out of the collaboration between Will Cavendish, an architecture student at Edinburgh University, and Oliver Collier, studying music technology, the PufferSphereTM, and soon to be released Puffer Immersive Mobile Sphere (PIMS), provides a 360-degree viewing window. Their company Pufferfish Ltd was formed in 2004 to commercialise (使商业化) their ideas for portable visual display systems.

The PufferSphere system includes projection (投影), specific lens technology and computer equipment fitted in to a base unit box from which the screen inflates to an imposing three metres tall. Cavendish says, "It's like a balloon. All of our products at this stage involve inflatables. "

He continues, "We can use the screen in any way that we can use a flat screen. Because it's inflatable it's a very tactile (有触感的)product, people are often surprised when they approach the display. It's a dramatic sight in its own right but when you add the impact of moving imagery it takes on a life of its own. "

The PufferSphere experience means that "audiences can see the same film but from different perspectives and in different time frames," explains Cavendish. "Some of the best uses have been for disparate (异类的)audiences, where we've been doing music events or fashion shows using the displays to enhance the environment. Collier refers to it as a digital campfire because it takes a central role in an environment and captures the audience's attention. "

Cavendish describes the PIMS as the natural next step. "There's a huge growth in 3D modeling software but little development of how we can view it. Our latest product allows us to take the immersive experience of virtual reality and take it to the client. The PIMS can be set up on site and allows a group of people to be fully visually immersed within an environment at a human scale. "

"What we're doing is taking technology developed for the virtual reality industries such as military, oil and gas, construction and we're creating our own software and putting it into mainstream products." And, with the Puffer Immersive Mobile Sphere, we will literally be able to enter another sphere of virtual reality.

What is the most striking feature of the PIMS?

A.Its simplicity on structure.

B.Its special window for display.

C.Its commercialization since 2004.

D.Its music technology.

Section B

Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.

We love what we can do with our computers, yet when it comes to reading, given the choice, most people prefer printing their material. But a new device to be launched early next year by Plastic Logic will be utterly different from any electronic reader we are familiar with.

The technology was originally developed at Cambridge University's Cavendish Laboratory in the 1990s, where they discovered how to put transistors(电晶体) on plastic. The use of plastic in these devices is the big idea, as Dr. Seamus Burns explains, "we are making the display on plastic rather than glass. Our core technology is the ability to put electronics on a plastic substrate(基质)rather than a glass substrate. This means that we can make a display device that is thin, lightweight and robust, without it being prohibitively expensive. "

The device is initially aimed at business people who carry around briefcases full of papers. It supports the standard software used to read and create documents, but also allows for the reading of newspapers, magazines and books. The device is built to make for easy reading, "this new media looks like paper and uses reflective light so it's easier on the eye," says Burns. "It doesn't have a backlight, consumes much less power, and you can turn power off between image updates. So, if you were to read a book, it uses no power whatsoever between page turns, which adds massively to the portability as it has a longer battery life. "

At the moment most people tend not to read on electronic devices, but the Plastic Logic reader may prove a milestone simply because it is more like paper in its size and durability. "Not only is the display made on a lighter material, it also isn't as fragile as glass. It needs less protection so the device can be made in a less bulky way. Secondly, the display is much larger, at 10.7 inches diagonally(斜对地), making the device closer to a sheet of paper. "They are also giving it touchscreen capability, which makes it more tactile and removes the need for extra buttons on the device." In the future people will do a lot more reading digitally," says Burns. And this device looks like a step in that direction.

Which of the following is true according to the first paragraph?

A.People can't do their reading without computer.

B.Most people are tired of computer reading.

C.Paper reading holds the most people if condition allowed.

D.Paper reading will be replaced in the coming years.

Lawrence Bragg, the Cavendish Professor of Experimental Physics, once wrote: "I will try t
o define what I believe to be lacking in our present courses for undergraduates. They do not learn to write clearly and briefly, marshalling their Points in due and aesthetically satisfying order, and eliminating inessentials. They are inept at those turns of phrase or happy analogy which throw a flying bridge across a chasm of misunderstanding and make contact between mind and mind. They do not know how to talk to people who have a very different training from them, and how to carry conviction when plans for action of vital importance to them are made." Perhaps this would not matter too much if physical science students were destined only for the backrooms of scientific laboratories. But recent trends indicate that many science graduates end up in careers far from their initial training. Many a physics graduate is to be found predicting the future market in the Square Mile; many a chemist is hyping it up in public relations. One of the main complaints of those graduates who leave science is that their course concentrated on producing students equipped to follow a research career, and that the underlying assumption was that such research would be carried out in an academic environment. Those who eventually find themselves elsewhere, whether as scientific researchers or in another capacity, often feel ill equipped for the environment of commerce and industry. These young people often have to write off their last three years' training. At most, all they got from their BSc was a grounding in scientific logic and numeracy. The factual content of their subject was just so much excess baggage.

The academic scientific community which supplied the excess baggage can be heard loudly bemoaning the "loss" of talented young scientists. Yet academic scientists also complain about scientific illiteracy in exactly those non-science professions, which are now welcoming science students.

Perhaps if there were less moaning and greater acceptance of this intellectual osmosis(渗透), the exodus could be turned to everyone's advantage. The refugee graduates ought to be able to think of their scientific knowledge and training as a bonus. It ought to make a positive, constructive contribution to their working lives, and be a source of insight for their colleagues. At the same time, the scientific community should be reaping the benefit of this broad and influential distribution of people who are sympathetic to science.

The reason why this is not the case is that science graduates are often unable to share their science with their nonscientific colleagues. They are unable to communicate. Instead of building Bragg's "flying bridge" they find themselves erecting barriers whenever called upon to explain scientific concepts in everyday terms. Attitudes in the scientific community are changing. In 1985, the Royal Society published a report on the public understanding of science in Britain. Its conclusions took many members of the scientific community by surprise.

The report advocated increased cooperation with the media, more training in communication skills for scientists and wider science education. It also recommended that communication skills be an integral part of every undergraduate science course. The response in British universities has been patchy, to say the least, the reasons are not clear. It may be that nothing more than straightforward inertia is responsible. Being more charitable, academic scientists may simply feel their job is to teach science and that any attempts to delve into the art of communication will be ill received by both students and the outside world. However, there is evidence to suggest these fears are ill founded. For example, the departments of chemical and electrical engineering at Imperial College, London, have for many years offered their students tuition in giving talks. The
