第2篇：Mind-reading
(参考教材，好像其中一个题选项提问与教材不一样)
32. Mind-reading1 Machine
A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what's happening in their brains.
When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons are responsible for this processing.
The fMRI (functional Magnetic Resonance Imaging ) 2 brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.
Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize3 which parts of the brain receive more oxygen-rich blood--and therefore, which parts are working to process information.
An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.
The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.
In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.

第3篇：youth emancipation in Spain
The Spanish Government is so worried about the number of young adults still living with their parents that it has decided to help them leave the nest.
Around 55 percent of people aged 18-34 in Spain still sleep in their parents’ home, says the latest report from the country’s state-run Institute of Youth.
To coax young people from their homes, the Institute started a “Youth Emancipation” programme this month. The programme offers guidance in finding rooms and jobs.
Economists blame young people’s family dependence on the precarious labour market and increasing housing prices. Housing prices have risen 17 percent a year since 2000.
Cultural reasons also contribute to the problem, say sociologists. Family ties in south Europe – Italy, Portugal and Greece – are stronger than those in middle and north Europe, said Spanish sociologist Almudena Moreno Minguez in her report “The Late Emancipation of Spanish Youth Key for Understanding”.
“In general, young people in
