Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with high energy density(密度)”，said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanreal systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.
71. Which of the following is true of Jae Kwon?
A. He teaches chemistry at MU.
B. He developed a chemical battery.
C. He is working on a nuclear energy source.
D. He made a breakthrough in computer engineering.
细节理解题。根据第三段的叙述可知Kwon在研究一种原子能电池，所以C项正确。

参考译文除了那些人们所熟知的能源，例如天然气、煤、石油、核能，我们还应该关注其他许多新能源。水力电能和潮汐能就是其中的两种。这两种能源的相似之处在于，它们都是可再生能源。但是，水力电能比潮汐能的使用范围要更广。事实上，水力电站已经为全世界提供了大量电能，而潮汐电站仍然处于最初的发展阶段。就地理位置而言，水力电站工程要建在湖泊和河流地区，而潮汐电站只能建在潮汐发生频率很高的河流入口处。不幸的是，这些地方很有限。目前，水力电站主要分布在挪威、加拿大、瑞典和巴西，而潮汐电站则位于法国、俄罗斯和中国。至于资金投入，两种电站均需要高投入。另一方面，它们所产出的利润都很低。实际上，与煤、石油和核能等传统能源相比，一个大型水力电站发电的成本要低。在生产资金方面，潮汐电站也要优于核能和石油电站。和水力电站一样，潮汐电站的预期寿命也很长。据估计，它们都能够运行100多年。在供电的持续性方面，潮汐电站不同于水力电站，因为潮汐电站只能间隙性供电。而水力电站能够持续供电。答案及解析 21．C 【精析】compatible兼容的；parallel平行的；similar类似的； identical完全相同的，一模一样的；similar常与介词in连用表示在某方面相似，这里表示水力电能和潮汐能的相似之处在于两者都可再生，故选C。

第一篇
Putting Plants to Work
Using the power of the sun is nothing new.People have had solar-powered calculators and buildings with
solar panels（太阳能电池板）for decades. But plants are the real experts. They' ve been using sunlight as an
energy source for billions of years.
Cells in the green leaves of plants work like tiny factories to convert sunlight, carbon dioxide（二氧化
碳）,and water into sugars
and starche（淀粉）,stored energy that the piants can use. This conversion
process is called photosynthesis (光合作用）Unfortunately, unless you' re a plant, it's difficult and
expensive to convert sunlight into storable energy. That's why scientists are taking a closer look at exactly
how plants do it.
Some scientists are trying to get plants,or biological cells that act like plants, to work as very small
photosynthesic power stations. For example, Maria Ghirardi of the National Renewable Energy Laboratory in
Golden. Cobo.,is working with green algae（水藻）.She's trying to trick them into producing hydrogen
instead of sugars when they perform photosynthesis. Once the researchers can get the algae working efficient-
ly ,the hydrogen that they produce could be used to power fuel cells in cars or to generate electricity.
The algae are grown in narrow-necked glass bottles to produce hydrogen in the lab. During photosynthe-
sis , plants normally make sugars or strchds. "But under certain conditions,a lot of algae are able to use the
sunlight energy not to store starch , but to make hydrogen."Ghirardi says. For example ,algae will produce hy-
drogen in an airfree environment. It' s the oxygen in the air that prevents algae from making hydrogen most of
the time.
Working in an airfree environment, however, is difficult. It's not a practical way to produce cheap
energy. But Ghirardi and her colleagues have discovered that by removing a chemical called sulfate（硫酸盐）
from the environment that the algae grow in, they will make hydrogen instead of sugars,even when air
is present.
Unfortunately, removing the sulfate also makes the algae's cells work very slowly,and not much
hydrogen is produced. Still ,the researchers see this as a first step in their goal to produce hydrogen efficiently
from algae. With more work,they may be able to speed the cells' activity and produce larger quantities
of hydrogen.
The researchers hope that algae will one day be an easy-to-use fuel source. The organisms are cheap to
get and to feed, Ghirardi says,and they can grow almost anywhere:"You can grow them in a reactor, in a
pond. You can grow them in the ocean. There's a lot of flexibility in how you can use these organisms."
A: They have been using it for billions of years.
B: They are the real experts in producing it.
C: They have been a source of it.
D: They have been used to produce it.
文章的第三段说，科学家企图将植物或植物类生物细胞作为微型光合作用能源供应站 来研究，并举例说，他们正在用绿藻进行实验，若成功，绿藻所产生的氢气将可用来为汽车的燃 料电池充电。所以答案是D。
由文章第四段最后两句“…algae will produce hydrogen in an airfree environment.It' s the oxygen in the air that prevents algae from making hydrogen most of the time.（……绿藻在没有空气 的环境下能产生氢气，是空气中的氧气在阻止绿藻制造氢气。）”可知选B。
A、B都不是正确答案，因为短文的第五段、第六段告诉我们，remove the sulfate和work in an airfree environment都是可能的，但问题是两者都有弊端，使氢气的制造不那么容易。C所 述内容就是困难之一：绿藻细胞因为没有了sulfate而减缓工作速度，因此产生不了多少氢气。 D项与第四段末尾所说的“是空气中的氧气在阻止绿藻制造氢气”矛盾。故选C。
根据最后一段Ghirardi所说的话可知，绿藻可以在任何地方生长，而且用途广泛，联系 此段首句可知Ghirardi所说的意在表示绿藻易于广泛应用，有望成为一种好的能源。故选A。 B项未提到，C项“它们将被到处种植”也不是Ghirardi的话的真正意思，他只是说绿藻易于广 泛种植。D项是对文中“feed”一词所在句的错误理解，feed在此意为“养”。第二篇 文章主要讲的是公共土地在美国能源生产方面的重大作用，分别从产量、税收、未开发的传 统能源、替代能源占全国的份额以及能源开发需求等方面进行了介绍。
