8．What do we know about Dan Smiley? A．He lived in New York City. B．He was a scientific researcher. C．He owned the Mohonk Preserve. D．He kept a record of wildlife.
解析：选D 细节理解题。根据第二段第二句可知，20世纪30年代，这个地区原来的主人的一个后人Dan Smiley记录了该地区的动植物信息。故D项正确。
9．What does the underlined word “it” in Paragraph 4 refer to? A．The birds' birth. C．The nest building.
B．The birds' arrival. D．The insects' appearance.
解析：选B 代词指代题。根据第四段第一句可知，对于鸟类来说，在春天适时到达很重要，因为它们需要用昆虫的出现来确定它们到达的时间。又结合本段中的“Once the eggs hatch ...when the insects are most abundant”可知， 一旦这些蛋孵化，它们就有了幼鸟，所以它们需要在昆虫数量最多的时候安排时间到达。据此可知，it指代鸟的到达，故B项正确。
10．What does Megan Napoli think of Smiley's long-term record? A．It has affected the birds' migration. B．It challenges the previous research. C．It has changed official attitudes. D．It is of great value to her research.
解析：选D 细节理解题。根据第三段第二句可知，Megan Napoli认为Smiley
收集的长期观测数据对研究气候变化的影响非常有用。故D项正确。
11．What can we learn from Napoli's research? A．It is totally based on Smiley's long-term notes. B．Scientists have to rely on more personal data. C．Climate change affects birds' migration time. D．It contributes greatly to other personal research.
解析：选C 细节理解题。根据第五段的内容尤其是最后一句“Her results suggest that they do”可知，Napoli的研究说明气候的变化影响鸟类的迁徙时间，故C项正确。
D
(2020·太原模拟)Architect Vincent Callebaut recently introduced a plan for high-flying teams of self-sufficient aircraft that are one part of airship cities and one part of hydrogen-producing floating farms. Called hydrogenase (氢化酶), the aircraft are 100% emission-free and are capable of creating hydrogen without consuming land needed for crops or forests.
We've seen futuristic airships before, but never one that doubles as a hydrogen-producing flying farm! Designed for the South China Sea near Hainan, Callebaut's hydrogenase airships are completely self-sufficient and contain a specialized breed of seaweed that absorbs sunlight and CO2 to produce hydrogen.
According
to
the
architects,
“The
output
obtained
from
micro-seaweed is superior to that of using farming to produce biofuel. 330 grams of seaweed produce 1,000 liters of hydrogen per day, while soybeans produce roughly 1,000 liters of oil per hectare (公顷). A hectare of seaweed could thus produce much more biofuel than a hectare of soybeans.”
In addition to providing a clean source of renewable energy, hydrogenase airships offer an eco-friendly means of transportation. Although certainly slower than ordinary planes, the airships are nearly silent and require a very little basic structure to take off and land. The architects also suggest that the airships should provide disaster relief for remote areas, and be used as flying hospitals and aid centers. Each hydrogenase airship is covered with flexible photovoltaic cells (光电池)．The interior features room for housing, offices, scientific laboratories, and entertainment, and a series of bioremediating (生物降解) vegetable gardens provide a source of food while recycling waste. Hydrogenase is certainly for the futuristic concept, but it does use a set of technologies being developed today — and perhaps one day we will see fantastic ideas like this develop.
语篇解读：本文主要介绍了氢化酶飞艇的优点：完全自给自足，含有一种可以吸收阳光和二氧化碳从而产生氢气的特殊种类的海藻。用微型海藻能生产更多的生物燃料。除了提供一种清洁的可再生能源的来源外，还能提供一种环保的交通方式。 12．What do we know about Vincent Callebaut? A．He is working on a floating farm.
B．He compares many different airships. C．He has developed a self-sufficient aircraft. D．He has come up with a plan for new aircraft.
解析：选D 细节理解题。根据第一段第一句可知，Vincent Callebaut提出了一个新的飞行器计划。故选D项。
13．Why do the hydrogenase airships contain seaweed? A．To produce oxygen. C．To absorb hydrogen.
B．To create hydrogen. D．To absorb harmful gases.
解析：选B 细节理解题。根据第二段第二句“... contain a specialized breed of seaweed that absorbs sunlight and CO2 to produce hydrogen”可知，氢化酶飞艇包含海藻为的是产生氢气。故选B项。
14．What can we learn from Paragraph 3? A．Farms with seaweed produce more food.
B．Farms with seaweed are more efficient at producing biofuel. C．Soybeans can't be planted on the airships.
D．Farms with seaweed will surely replace traditional farmland. 解析：选B 推理判断题。根据第三段“The output obtained from micro-seaweed is superior to that of using farming to produce biofuel”和后面的例子可推断出，带海藻的农场在生产生物燃料方面效率更高。故选B项。
15．What does the text mainly talk about? A．The advantages of the airships.
