Single-parent Kids Do BestSingle mums are better at raising their kids than two parents-at least in the bird world.Mother zebra finches have to work harder and raise fewer chicks on their own,but they also produce more attractive sons who are more likely to get a mate.The finding shows that family conflict is as important an evolutionary driving force as ecological factors such as hunting and food supply.______(46)In evolutionary terms,the best strategy for any parent in the animal world is to find someone else to care for their offspring,so they can concentrate on breeding again.Soit's normal for parents to try to pass the buck to each other.But Ian Hartley from the University of Lancaster and his team wondered how families solve this conflict,and how the conflict itself affects the offspring.______(47)They compared single females with pairs,by monitoring the amount of food each parent collected,and removing or adding chicks so that each pair of birds was raising four chicks,and each single mum had two-supposedly the same amount of work.But single mums,they found,put in about 25 per cent more effort than females rearing with their mate. ______(48)"The offspring suffer some of the cost of this conflict,"says Hartley.The cost does not show in any obvious decrease in size or weight,but in how attractive they are to the opposite sex.When the chicks were mature,the researchers tested the"fitness"of the male offspring by offering females their choice of partner.______( 49)Sexual conflict has long been thought to affect the quality of care given to offspring,says zoologist Rebecca Kilner at Cambridge University,who works on conflict of parents in birds."But the experimental evidence is not great.The breakthrough here is showing it empirically."More surprising,says Kilner,is Hartley',S statement that conflict may be a strong influence on the evolution of behaviour,clutch size and even appearance."People have not really made that link,"says Hartley.A female's reproductive strategy is usually thought to be affected by hunting and food supply.______(50)______(50)A:To avoid being exploited,mothers with a partner hold back from working too hard if the father is being lazy,and it's the chicks that pay the price.B:To find out,they measured how much effort zebra finch parents put into raising their babies.C:Those males reared by single mums were chosen more often than those from two一parent families.D:With two parents around,there's always a conflict of interests,which can have a detrimental effect on the quality of the offspring.E:Kilner says conflict of parents should now be taken into account as well.F:It turned out that single mums had greater influence on their offspring.

The trick in food photography is to show the food looking fresh，so many dishes have stand-ins，just as movie stars do．“When I get my lights and cameras set up，I remove the stand-in and put in the real thing，”explains Ray Webber，who photographs food for magazine advertisements．“Sometimes I have to brush the meat with its juices because it may have dried out a bit．A and when I‘m shooting（拍照）something like tomatoes，I always carry water to spray them with dew just before I shoot．”
Shooting food outdoors has special problems．“I‘m always worrying about flies or worms crawling up a glass，”Webber explains，“my worry is that someday a dog will come up from behind and run off with the food．”Once Webber was shooting a piece of cheese outdoors and needed something to make its color beautiful．Finally he found it：a weed with lovely blue flowers．When the shot appeared，several people were horrified-the weed was deadly nightshade！
（）Just before being photographed，some meats and vegetables are_______．
