　　If a woman has an extra piece of cake,don’t blame it on greed,blame it on her brain.

　　Scientists have found that women’s brains react to food very differently—and much more strongly—than men’s.Academics found that decades of dieting pressure on women and advertising have programmed certain parts of the female brain to react strongly when faced with any kind of food.Men,on the other hand,are not usually as obsessive (着迷的) about what they eat.

　　Dr.Rudolf Uher and his colleagues at the Institute of Psychiatry in King’s College London used brain scanning technology,known as functional magnetic resonance imaging (fMRI),to look at the brains of eighteen men and women.

　　The volunteers were given images of food to look at,as well as food to taste.Their brain reactions were observed by the scientists.

　　They found that the female brains reacted much more strongly than those of males.

　　The same reaction did not happen when they were shown non-food images.The team believe this means women think more about food than men tend to do.

　　Dr.Uher said,“This could be related to biological differences between men and women.But the more likely explanation is that women have a more complicated reaction to food because of social pressure.

　　Professor Carey Cooper,psychology and health professor at Lancaster University,said,“For centuries women have had a providing role — preparing and cooking food for their families.And it is part of that rule to make sure the food is safe.They will therefore be much more sensitive to food than men are,and I would not be surprised if that was now built into their DNA.If the female brain reacts to food because it historically has developed neural (神经的) pathways to do this,then food will be the way they express their stress.Food actually,is a comfort for women.”

　　But other experts have said that more research must be done before the results can be proved.American scientist Angelo del Parigi of the John B.Pierce Laboratory in New Haven,Connecticut,said,“Looking at an fMRI alone cannot make sure whether the stronger reaction in women is due to innate (天生的) differences or a learned process.

　　1.Dr.Uher and his colleagues carried out the research by comparing 　. 

　　A.fMRI’s effectiveness on women and men

　　B.women’s and men’s reaction to different images

　　C.volunteers’ reaction to food before and after meals

　　A.told to do so for a long time

　　B.influenced by advertisements

　　C.forced by powerful social influences

　　D.born to do so due to biological reasons

　　3.According to Professor Carey Cooper,women 　.

　　My husband and I insisted that our children were old enough to clean their rooms and make their beds.But they thought 　1　.My complaints,even self-justified shouting,were always landing on 　2　 ears.Very often a whole hour’s scolding would end with their 　3　 into tears,and I felt very frustrated.I realized I needed to 　4　 my method of “mothering”. 

　　One day when they were at school,I spent some time 　5　 their rooms.On their desks,in plain 　6　,I left the cards:“Dear Bill(the other card was 　7　 to Sarah),your room was messy this morning and I’m sure you like it clean.Love,the Room Fairy.” 　8　 arriving back,the children were 　9　 excited to receive the little note from the Room Fairy.The next day,their rooms were fairly tidy.Sure enough,there was another note from the Room Fairy 　10　 for them,thanking them for their nice “gift” of a clean room and 　11　 asking them to play a certain violin 　12　.Each day,thank-you notes would be written differently to keep the ideas 　13　. 

　　Sometimes the Room Fairy would propose a little 　14　: “If you can finish your homework and 　15　 your lessons before dinner,I’d like to watch a particular television program with you tonight.” Sometimes some colored markers or other little items would be left in 　16　 of well done jobs the day 　17　. 

　　　18　 I can’t remember how long “the Room Fairy” continued leaving her love notes.When they were age appropriate,we used various versions of PostIts (贴条).The bathroom mirror became the 　19　 centre of our home.Appointments,notices about visiting relatives,lesson schedules,and changes in plans could be posted. 

　　We all benefited from and 　20　 the idea of sharing reminders and daily details of life through notes.I believe the true advantage of the Room Fairy notes survives in our frequent and enjoyable communication.

　　C.doubtfully D.otherwise

　　C.neither D.either
