14、uld be assured, despite an annual 40m spent by the Department of Health on all kinds of research.However, we do have to challenge the unthinking complaint that the sector does not do enough in taking ideas to market. The most recent comparative data on the performance of universities and research in
15、stitutions in Australia, Canada, USA and UK shows that, from a relatively weak starting position, the UK now leads on many indicators of commercialization activity.When viewed at the national level, the policy interventions (interference) of the past decade have helped transformed the performances o
16、f UK universities. Evidence suggests the UKs position is much stronger than in the recent past and is still showing improvement. But national data masks the very large variation in the performance of individual universities. The evidence shows that a large number of universities have fallen off the
17、back of the pack, a few perform strongly and the rest chase the leaders.The core objective for universities which are research-led must be to maximize the impact of their research efforts. Their purpose is not to generate funds to add to the bottom line of the university or to substitute other incom
18、e streams. Rather, these universities should be generating the widest range of social, economic and environmental benefits. In return for the scale of investment, they should share their expertise (expert knowledge or skill) in order to build greater confidence in the sector.Part of the economic rec

On the evidence presented in my report, there are three dozen universities in the UK which are actively engaged in advanced research training and commercialization work.If there was
20、a greater coordination（协调）of technology transfer offices within regions and a simultaneous (happening at the same time) investment in the scale and functions of our graduate schools, universities could, and should, play a key role in positioning the UK for the next growth cycle.【小题3】69.

96、future【2014届广东珠海市高三9月摸底】(A)Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings. The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and
97、ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves. Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes
98、pain to human ears. In water, a decibel level of one hundred and ninetyfive would have the same effect. Some scientists have suggested setting a noise limit of one hundred and twenty decibels in the oceans. They have observed that noises at that level can frighten and confuse whales（鲸鱼）. A team of A

This seriously affected the whales ability to exchange information and find their way. S

Engineers say the driverless cars are safer than autos with people behind the wheel because the computers react much more quickly than humans.The Carbot is still in very early testing stages. Experts agree that
115、 it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the drivers seat of a driverless car.

Dog remains fro
203、m a Fairbanks-area gold mine helped the scientists reach their conclusion. Leonard, an evolutionary biologist, collected DNA from 11 bones of ancient dogs that were locked in permafrost(永冻层) until Fairbanks miners uncovered them in the 1920s. The miners donated the preserved bones to the American Mu
204、seum of Natural History in New York City, where they remained untouched for more than 70 years. After borrowing the bones from the museum, Leonard and her colleagues used radiocarbon techniques to find the age of the Alaska dogs. They found the dogs all lived between the years of 1450 and 1675 A.D.,
205、 before Vitus Bering and Aleksey Chirikov who were the first known Europeans to view Alaska in 1741. The bones of dogs that wandered the Fairbanks area centuries ago should therefore be the remains of “pure native American dogs,” Leonard said. The DNA of the Fairbanks dogs would also expose whether
206、they were the descendents of wolves from North America. Along with the Fairbanks samples, the researchers collected DNA from bones of 37 dog specimens(标本) from Mexico, Peru, and Bolivia that existed before the arrival of Columbus. In the case of both the Alaska dogs and the dogs from Latin America,
207、the researchers found that they shared the most genetic material with gray wolves of Europe and Asia. This supports the idea of domestic dogs entering the New World with the first human explorers who wandered east over the land bridge. Leonard and Waynes study suggests that dogs joined the first hum
