第一篇 Immigration and Problems
Hundreds of thousands of people supporting immigration rights in the US filled streets all over America in early 2006. Many held signs and American flags and asked to be treated as citizens - not criminals. Many of these supported legislation from Senator John McCain that would open a path to citizenship to immigrants who were already in the country illegally. Proposed legislation from other politicians called for stricter measures - including rounding up undocumented immigrants and sending them back to their home countries.
Canadian officials say that immigration applications continue to rise. Some want to keep the doors open. They need the labor. About 400，000 immigrants were allowed into the country in 2005， according to the Canadian Government statistics. However， all this growth means that cities need to adapt. Newcomers don‘t always make a smooth transition into jobs for which they are skilled. So industries are using mentoring programs to help new immigrants find proper jobs.
With the large numbers of undocumented African immigrants arriving in the Canary Islands and showing no sign of abating， the Spanish Government has decided to get tough. There will be no more mass amnesties for illegals， and anyone coming to Spain without permission will be sent back， the government has announced. About 23，000 migrants landed on the islands in 2006， and riots have erupted in some crowded reception centers. This has promoted local authorities to appeal to the United Nations for help.
France‘s new immigration and integration law gives the government new powers to encourage high-skilled migration. It takes effect in 2007. The new law authorizes the government to identify particular professions where France has a talent shortage. Then the government will help these identified employers find immigrant workers with needed skills or qualifications. The selected foreign employees will be granted “skills and talents” visas， valid for three years. But some concern that itll cause brain drain in developing countries.
31 Many immigrants swarmed into streets in the US in early 2006， demanding that they should be treated as
A animals
B citizens
C civilians
D criminals
第二篇 Mind-reading 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) 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 visualize 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 volunteer‘s 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.
36 What is responsible for processing the information sent by your eyes?
A A small region of the brain.
B The central part of the brain.
C Neurons in the brain.
D Oxygen-rich blood.
