15．Their cheery song brightens many a winter's day．But robins（知更鸟） are in danger of wearing themselves out by singing too much．Robins are singing all night一 as well as during the day，British-based researchers say．
David Dominoni，of Glasgow University，said that light from street lamps，takeaway signs and homes is affecting the birds'biological clock，leading to them being wide awake when they should be asleep．
Dr Dominoni，who is putting cameras inside nesting boxes to track sleeping patterns，said lack of sleep could put the birds'health at risk．His study shows that when robins are exposed to light at night in the lab，it leads to some genes being active at the wrong time of day．And the more birds are exposed to light，the more active they are at night．
He told people at a conference，"There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing．Singing is a costly behaviour and it takes energy．So by increasing their song output，there might be some costs of energy．"
And it is not just robins that are being kept awake by artificial light．Blackoiids and seagulls are also being morenocturnal．Dr Dominoni said，"In Glasgow where I live，gulls are a serious problem．I have people coming to me saying′You are the bird expert．Can you help us kill these gulls？'．During the breeding（繁殖）season，between April and June，they are very active at night and very noisy and people can't sleep．"
Although Dr Dominoni has only studied light pollution，other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise．
However，some birds thrive（兴旺）in noisy environments．A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery．It is thought that they are capitalizing on their predators（天敌）fleeing to quieter areas．
22．According to Dr Dominoni's study，what causes robins to sing so much？B
A．The breeding season．
B．The light in modem．
C．The dangerous environment．
D．The noise from heavy machinery．
23．What is the researchers'concern over the increase of birds'song output？B
A．The environment might be polluted．
B．The birds'health might be damaged．
C．The industry cost might be increased．
D．The people's hearing might be affected．
24．What does the underlined word"nocturnal"in Paragraph 5mean？A
A．Active at night．
B．Inactive at night．
C．Active during the day．
D．Inactive during the day．
25．Why do some birds thrive in noisy environments？A
A．Because there are fewer dangers．
B．Because there is more food to eat．
C．Because there is less light pollution
D．Because there are more places to take shelter．

20．Seth DeBolt is a plant scientist at the University of Kentucky．He and other scientists want to find：a source of fuel that the poor people in rural areas of developing countries could use，to supply themselves with electricity．
Professor DeBolt went on a study trip：to rural areas in Indonesia．He saw that，everywhere he went，there was little waste in the use of agricultural products．Everything that farmers grew was used for something； Even the remains of fruit that people did not eat were fed to chickens．
Little waste  meant there was little that could  be  used for fuel．Growing fuel crops would take land away from food crops，That was something Professor DeBolt did not want．to do．But he found some items that were in plentiful supply and：l would not cause the competition between food and fuel．Coconut shells：（椰壳） are generally thrown out．Yet Professor DeBolt says there is a Lot of energy stored in them．He says they have an excellent heating，value which can be compared to coal．All someone needs is a way to release that energy．
A company in India is using small generators（发电机） in Villages to make electricity from remains of rice．The process used is called gasification（气化）．Heating plant matter in a low-oxygen condition releases gases．These can  be burned in an engine that powers a generator．Professor DeBolt says he and his team see possibilities of coconut power．
The researchers say these systems could provide as much as thirteen percent of the energy needs of a country like Indonesia．Other tropical countries with large crops of coconuts and similar fruit could benefit as well．But Professor DeBolt says this is not a perfect solution There are technical rubs，like how to safely deal with the．dangerous waste that gasification can produce And it needs much money to make these projects start．
