2题:Scraps of food could soon be helping power your home, thanks to an ultra-cheap bacteria-driven battery. Its developers hope that instead of feeding the dog or making garden compost(混合肥料) ,organic household waste could top up your home’s electricity.
Although such "microbial fuel cells" (MFCs)have been developed in the past, they have always proved extremely inefficient and expensive. NowChris Melhuish and technologists at the University of the West ofEngland(UWE、inBristol have come up with a simplified MFC、that costs as little as £10 to make.
Right now, their fuel cell runs only on sugar cubes, since these produce almost no waste when broken down, but they aim to move on to carrot power. "It has to be able to use raw materials, rather than giving it a refined fuel," says Melhuish.
Inside the Walkman-sized battery, a colony ofE、coil bacteria produce enzymes that break down carbohydrates, releasing hydrogen atoms. The cell also contains chemicals that drive a series of redox, or reduction and oxidation reactions, stripping electrons from the hydrogen atoms and delivering them steadily to the fuel cell’s anode(正极). This creates a voltage that can be used to power a circuit.
To prove the MFC、works, the researchers are using it to power a small light-sensitive robot.And when a number of the cells are connected in series, they could power domestic appliances, running a 40-watt bulb for eight hours on about 50 grams of sugar.
Earlier MFCs were inefficient because they relied on energy-hungry filters and pumps.By experimenting with different anode materials, the UWE、team have figured out how to make their system work: they dump the bacteria and redox chemicals directly into the cell.
In its current form, the UWE、team says its organic battery can produce eight times as much power as any previous MFC、But Melhuish wants to improve this, both by scaling it up and finding a better mix of redox chemicals.
Chris Melhuish and technologists are trying to use household wastes to ______.A.feed domestic animals

B、make garden compost
C.produce electricity
D.manufacture bacteria

4题:The Vikings have left many traces of their settlement which are still visible today.Archaeology provides physical evidence of their conquests, settlement and daily life. The study of place names and language shows the lasting effect which the Viking settlements had in theBritish Isles, andDN
A、analysis provides some insights into the effect the Vikings had on the genetic stock of the countries where they settleD、All of this provides valuable information, but the only reason that we have an idea of the "Vikings" as a people is their appearance in the written sources.
Unfortunately, the value of the written evidence is limiteD、Not a lot of evidence survives, and much of what we have is either uninformative or unreliable. Many popular ideas about Vikings are nineteenth-century inventions. Others are the result of early historians accepting sources which modern scholars now regard as completely unreliable. In Scandinavia the VikingAge is regarded as part of prehistory because there are practically no contemporary written sources.Even in westernEurope, the VikingAge is often seen as part of the "DarkAges", from which comparatively few historical records have surviveD、
Surviving accounts of Viking activity were almost exclusively written by clergymen (神职人员). These monastic chronicles (编年史) outline broadly what happened, at what date. There are also sources of a more directly religious nature, such as the much-quoted letters ofAlcuin, and Wulfstan’s famous "Sermon of the Wolf ", both of which chose to interpret the Viking raids as God’s punishment on theAnglo-Saxons for their sins.Even the chronicles reflect the fact that the Vikings often attacked monasteries for their wealth, which created an obvious bias against them, and the hostile tone of these contemporary accounts has done much to create the popular image of Viking atrocities. However, modern historians have noted that the same sources showChristian rulers behaving equally unpleasantly, but without being condemned on religious grounds.
We tend to think of the Vikings as a race of Scandinavian warriors, but the reality is more complex. Raids on theBritish Isles and the coasts of France and Spain were the work of Vikings from Norway andDenmark. The word Viking means one who lurks in a "vik" or bay, in effect, a pirate.
The word "Viking" has come to describe a whole new age inEurope between about 800 and 1150. This is despite the fact that Vikings were not just pirates and warriors but also traders and colonists.But at the start of the VikingAge in the last decade of the 8th century, loot and adventure were the main goals of the Norwegians who raided in Scotland and Ireland and of theDanes who attackedEnglanD、Gold and silver treasures accumulated by the great monasteries could be converted into personal wealth and thus power, and captives could be sold as slaves. What better way for the young sons of good families to earn their way and see the world
At that time, people’s attitude toward being a pirate is ______
A、negative

B、conflicting
C.positive
D.controversial
