7 . Researchers say a new electrical device placed in three paralyzed patients has helped them walk again. The lower bodies of the three patients were left paralyzed after they suffered spinal(脊柱的)cord injuries. But a device implanted in the spinal cord was able to send electrical signals to the muscles to permit them to stand, walk and exercise.

Scientists have discovered that neurons—which receive and send signals for muscle movements—often still work in injured patients with serious spinal cord injuries. However, past research into spinal cord injuries has centered on the stimulation of neurons. Now in the latest experiment led by Gregoire Court in e and Jocelyne Bloch of the Swiss Federal Institute of Technology in Lausanne, three paralyzed men were implanted a new electrical device designed to copy an action of the brain, in which it sends signals to the spinal cord that result in muscle movement. When the spinal cord receives the brain signals, it stimulates a collection of nerve cells that can activate different muscles.

The researchers reported that all three patients who got the spinal cord implant were able to take their first steps within an hour after receiving them. Over the next six months, the patients regained the ability to take-part in more advanced walking activities, the study found. They were also able to ride bicycles and swim in community settings.

Unlike other attempts to help paralyzed patients walk by stimulating nerves through the back of the spine, Court in e said that his team redesigned the devices so signals would enter the spine from the sides. This method permits more direct targeting and activation of spinal cord areas, he said.

The team then developed artificial intelligence (AI) systems linked to the device. The AI controls electrodes on the device to send signals to stimulate individual nerves that control muscles needed for walking and other activities. However, because the patients’ muscles were weak from not being used, they needed help with supporting their weight the researchers said. It also took some time for them to learn to work with the technology. Still, Bloch said, “The more they train, the more they start lifting their muscles, the more fluid it becomes.”

A．By using the AI system.

B．By sending the signals to the brain.

C．By making signals enter the spine from the sides.

D．By stimulating nerves through the back of the spine.

3. Which can best describe Bloch’s idea in the last paragraph?

A．Every garden has its weeds.	B．Put the cart (运货马车) before the horse.
C．It’s hard to please all.	D．Practice makes perfect.

4. What is the purpose of this text?

C．To recommend a treatment for paralyzed patients.

D．To compare a recent research with other previous researches.

This morning, I saw the shocking headline: “Passenger Dies When Car Crashes in Driverless Mode”. In the article,     1    (vary) people said that the public should oppose the idea of developing driverless cars. They said that some     2    (advance) in technology were unnecessary and could even be dangerous. Hence, we should cease     3    (accept) technology just because it is new. The newspaper reported that the car company had already apologized for the accident,     4     the families of the deceased said it was not enough. Nevertheless, the company still claimed that most people would be travelling in driverless cars one day soon.

    5     the one hand, there are many different groups of people around the world     6     live happily in the absence of new technology. Probably the most well known are the Amish, a group of Christians     7    (live) in rural America. They do not own or drive cars, watch TV, or use the Internet. They     8    (live) mainly as farmers since the 18th century, and they will probably be living the same way in the distant future. They advocate     9     simple life with an emphasis on hard work, family, and community. They think that is better than caring about luxuries or following the lives of the rich and famous. It could even be argued     10     the Amish’s quality of life is better since they live in and appreciate the natural environment rather than living in large, polluted cities.
