[简答题]European countries are buffeted by two global forces: One is climate change. The other is demography. Both prevalent pressures silently transform societies and the assumptions of public policy. The two have a lot in common. Both are easily recognized but less easily understood. Both are products of complex forces and unobtrusive influences. Both create huge effects from minuscule changes. A rise in global temperature by one degree or a fall in fertility by one point may sound trivial but, over 100 years, will make the earth unbearably hot, or reshape the size and composition of societies. Yet though every rich country has a climate-change policy, few have a population one (there are historical reasons for that). And just as everyone whinges about the weather, but does nothing about it, so everyone in Europe complains, but does nothing, about population. Received opinion holds that "demography is destiny" and that Europe is doomed by its death-spiral population numbers. Amer

[填空题]These countries aim to exploit two contradictory facts: information can now be stored anywhere, but energy is most efficiently consumed close to the source. ______ Internet Villages International has joined up with Atlantis Resources, an engineer of ocean turbines, to develop technology that could power local data centers with energy from Scotland ’s rugged seas Another company, Lockerbie Data Centres, is planning a green home and business communitycentered on a clean -energy data facility that runs on wind farms and a biomass plant.

• A. Thus several Scottish IT developers are now planning nearly $ 3 billion in green datacenters that tap into Scotland’s clean - electricity grid, 20 percent of which comes from renewables like wind.
• B. Google disputes this number, but there’s little doubt the IT industry is becoming one of the biggest contributors to global warming.
• C. Iceland, struggling to recover from the financial crisis, may he even better poised to become a gr
  

[单项选择]Two techniques have recently been developed to simplify research and reduce the number of nonhuman primates needed in studies of certain complex hormonal reactions. One technique involves the culturing of primate pituitary cells and the cells of certain human turnouts. In the other, animal oviduct tissue is transplanted under the skin of laboratory primates. Both culturing techniques complement existing methods of studying intact animals.
With an in vitro culturing technique, researchers are deciphering how biochemical agents regulate the secretion of prolactin, the pituitary hormone that promotes milk production. The cultured cells survive for as long as a month, and they do not require serum, a commonly used culture ingredient that can influence cellular function and confound study results. One primate pituitary gland may yield enough cells for as many as 72 culture dishes, which otherwise would require as many animals.
The other technique allows scientists to monitor cellu
A. reproductive organs of nonhuman primates
B. diseases of the pituitary glands
C. in vitro studies of pituitary hormones
D. techniques for studying hormonal reactions
