[单项选择]Scientists have long believed that constructing memories is like playing with neurological toys. Exposed to a barrage of sensations from the outside world, we connect together brain cells to form new patterns of electrical connections that stand for images, smells, touches and sounds.
The most unshakable part of this belief is that the neurons used to build these memory circuits are depletable resource, like petroleum or gold. We are each given a finite number of cells, and the supply gets smaller each year. That is certainly how it feels as memories blur with middle age and it gets harder and harder to learn new things. Maybe it’s time for this notion to be forgotten-or at least radically revised.
In the past two years, a series of confusing experiments has forced scientific researchers to rethink this and other assumptions about how memory works. The perplexing results of these experiments remind scientists how much they have to learn about one of the last great mysteri
A. The neurons used to build the memory are a depletable resource.
B. The reason of memory loss as one grows older is that the neurons are worn out with the increase of age.

Scientists have long warned that some level of global warming is a done deal—due in large part to heat-trapping greenhouse gases humans already have pumped skyward. Now, however, researchers are fleshing out how much future warming and sea-level rise the world has triggered. The implicit message: "We can’t stop this, so how do we live with it" says Thomas Wigley, a climate researcher at NCAR.
One group, led by Gerald Meehl at NCAR, used two state-of-the-art climate models to explore what could happen if the world had held atmospheric concentrations of greenhouse gases steady since 2000. The results: Even if the world had slammed on the brakes five years ago, global average temperatures would rise by about 1 degree Fahrenheit by the end of the 21st century. Sea levels would rise by another 4 inches over 20th-century increases. Rising sea-levels would continue well beyond 2100, even without adding water from melting glaciers and i

Car makers have long used sex to sell their products. Recently, how. ever, both BMW and Renault have based their latest European marketing campaigns around the icon of modern biology.
BMW’s campaign, which launches its new 3-series sports saloon in Britain and Ireland, shows the new creation and four of its earlier versions zigzagging around a landscape made up of giant DNA sequences, with a brief explanation that DNA is the molecule responsible for the inheritance of such features as strength, power and intelligence. The Renault offering, which promotes its existing Laguna model, employs evolutionary theory even more explicitly. The company’s television commercials intersperse clips of the car with scenes from a lecture by Steve Jones, a professor of genetics at University of London.
BMW’s campaign is intended to convey the idea of development allied to heritage. The latest product, in other words, should be viewed as the n
A. poverty,
B. extinction.
C. revolution.
D. evolution.
