Running after fireflies （萤火虫）on a warm summer night might become a rare childhood
memory if humans don't take action. There are over 2,000 different firefly species around the world, but their populations are decreasing due to artificial light pollution, pesticides （杀虫剂）and smaller habitat size.
A team of Tufts University-led researchers surveyed scientists and conservationists about the threats to firefly populations around the world. According to the study, one of the main threats to
fireflies in East Asia and South America is artificial light. Fireflies light up to attract mates, but they can easily mistake human-made lights as potential partners. Adult fireflies typically live only a few days, which doesn't give them long to find a mate.
Humans' destroying the insects' natural habitats creates another threat. During their larval phase （幼虫期），Malaysian fireflies live in riverside bushes that are often pulled out for human-made fish farms. In Europe, Lampyris fireflies are finding less food to eat due to the growing urbanization of what were once woods and farmlands. In Malaysia, adult pteroptyx fireflies that usually prefer to mate in specific trees next to rivers have to find new mating areas because the trees are being knocked down
的C
for farmhouses.
The study also looked at the effects of climate change, tourism, invasive （侵入的）species and water pollution. On a positive note, while fireflies around the world seem to be suffering from the previously mentioned issues, Big Dipper fireflies living in the US happen to be booming. \can survive pretty much anywhere,said Sara Lewis, a biologist from Tufts University.
The study urges countries where firefly populations are dwindling to take measures to preserve suitable habitats, lessen light pollution, reduce use of pesticides and develop better guidelines for tourism around known firefly areas.
8. What mainly causes the drop of the firefly population in East Asia? A. Light pollution. C Climate change.
B. Habitat loss. D. Food shortage.
9. Which of the following is more likely to adapt to the environment? A. The Malaysian firefly. C. The Pteroptyx firefly.
B. The Lampyris firefly. D. The Big Dipper firefly.
10. What does the underlined word “dwindling” in paragraph 5 mean? A. on the rise C. under control
11. What does the text mainly talk about? A. Watching fireflies is a rare childhood memory. B. Cooperation is the key to firefly protection. C. Urbanization becomes a main threat to fireflies. D. Human activities lead to less firefly population. 【答案】8. A 9. D 10. B 11. D 【解析】
这是一篇说明文。文章主要讲述了人类的行为包括光污染、杀虫剂和更小的栖息地使得萤火虫的数量减少。 【8题详解】
细节理解题。根据文章第二段第2句内容“According to the study, one of the main threats to fireflies in East Asia and South America is artificial light.”可知东亚和南美洲的萤火虫面临的主要威胁之一是人造光。因此，这一地区萤火虫数量减少的原因应是光污染。故选A项。
B. on the decrease D. out of control
【9题详解】
细节理解题。根据文章第四段第2句内容“On a positive note, while fireflies around the world seem to be suffering from the previously mentioned issues, Big Dipper fireflies living in the US happen to be booming. \from Tufts University.( 积极的一面是，当世界各地的萤火虫似乎都在遭受上述问题的困扰时，生活在美国的北斗七星萤火虫却在蓬勃发展。塔夫茨大学的生物学家萨拉·刘易斯说:“这些家伙几乎可以在任何地方生存。)”可知生活在美国的北斗七星萤火虫几乎可以在任何地方生存而使得它们数量激增。因此可知，北斗七星萤火虫能够适应环境。故选D项。 【10题详解】
词义猜测题。分析可知，划线单词所在句“where firefly populations are dwindling”应是之前名词的areas的定语从句，根据主句“The study urges countries to take measures to preserve suitable habitats, lessen light pollution, reduce use of pesticides and develop better guidelines for tourism around known firefly areas.”可知该研究敦促这些国家采取措施，保护合适的栖息地，减少光污染，减少杀虫剂的使用，并制定更好的指南，在已知的萤火虫地区周围旅游。因此可知，这些国家应是萤火虫数量在减少的国家。可推知划线单词“dwindling”应有“减少；下降”等含义，与选项B. on the decrease(在减少)表达含义一致。故选B项。 【11题详解】
主旨大意题。通读全文可知，文章结构为总分结构，首段提出了本文的话题中心“There are over 2,000 different firefly species around the world, but their populations are decreasing due to artificial light pollution, pesticides and smaller habitat size.( 世界上有超过2000种不同种类的萤火虫，但是由于人为的光污染、杀虫剂和更小的栖息地，它们的数量正在减少。)”，可知本文主要讲述了人类的行为使得萤火虫的数量减少。选项D.Human activities lead to less firefly population.合理概括了文章主旨要义。故选D项。
D
Swiss researchers have developed a machine that can keep human livers （肝脏）alive outside of the body for one week. At present, technology and methods are only able to keep human livers alive for up to 24 hours. The new machine is able to keep the liver active by performing several functions normally carried out by the human body.
Scientists from the University of Zurich in Switzerland developed the machine. The researchers say the purpose of their “Liver4Lifb” machine is to perform what they call liver perfusion （灌注）
operations outside of the human body. Perfusion is the process by which blood or other fluids are pumped through organs and tissue. The machine keeps the liver at the right temperature and moves it in a way that would be natural in the body. It uses a pump to fill the liver with blood acting like a replacement for a human heart. The machine also provides oxygen to the organ, controls red blood cell levels and removes waste.
The research team began their experiments using livers from pigs. After repeated testing and engineering development, the team said it was able to get the pig livers to survive for seven days with support only provided from the Liver4Life machine.
They also discovered that the system can work to repair damaged livers. In one test, the team connected the machine to 10 injured human livers that had been rejected for transplantation by all European medical centers. After seven days of perfusion treatment from the machine, six of the human livers fully regained important liver functions, the researchers reported.
The success of this unique perfusion system, developed over a four-year period by a group of surgeons, biologists and engineers, clears the way for many new applications in transplantation and cancer medicine, helping patients with no liver grafts （移植）available. 12. How does the machine keep the liver active? A. By pumping to fill it with kinds of medicine. B. By balancing the temperature of the body. C. By providing blood for the liver like a heart. D. By controlling its white blood cell levels. 13. What do we know about the system? A. It took researchers four periods to invent it. B. It is designed to repair damaged livers. C. It's possible that it may have a bright future. D. It needs more evidence to prove its functions. 14. In which section of a newspaper may the text appear? A. Education. C. Psychology.
15. What's the best title for the text?
A. New Machine Keeps Livers Alive for Full Week
B. Environment. D. Technology.
