Our ability to think has long been considered central to what makes us human. Now research suggests that our bodies and their relationship with the environment (1) even our most abstract thoughts. This includes thinking up random numbers or deciding (2) to review positive or negative experiences.
"Advocates of traditional (3) of cognition would be surprised," says Tobias Loetscher at the University of Melbourne in Parkville, Australia. "They (4) consider human reasoning to involve abstract cognitive processes without any connection to body or space."
Until recently, the (5) has been that our bodies (6) only to our most basic interactions with the environment, (7) sensory and motor processes. The new results suggest that our bodies are also (8) to produce abstract thought, and that even seemingly (9) activities have the power to influence our thinking.

Thirty years ago, such (12) led the linguist and philosopher George Lakoff at the University of Califor- nia, Berkeley, together with philosopher Mark Johnson at the University of Oregon in Eugene, to (13) "conceptual metaphor theory", the notion that we think of abstract concepts (14) how our bodies function. Now (15) for the theory has started to (16) in. In 2008, (17) , researchers found that people made to feel socially (18) reported feeling physically colder.

Gene therapy and gene based drugs are two ways we could benefit from our growing mastery of genetic science. But there will be others as well. Here is one of the remarkable therapies on the cutting edge of genetic research that could make their way into mainstream medicine in the coming years.
While it’s true that just about every cell in the body has the instructions to make a complete human, most of those instructions are inactivated, and with good reason: the last thing you want for your brain cells is to start churning out stomach acid or your nose to turn into a kidney. The only time cells truly have the potential to turn into any and all body parts is very early in a pregnancy, when so called stem cells haven’t begun to specialize.
Yet this untapped potential could be a terrific boon to medicine. Most diseases involve the death of healthy cells—brain cells in Alzheimer’s, cardiac cells in heart disease, pancreatic cells in diabetes, to name a few; if doctors could isolate stem cells, then direct their growth, they might be able to furnish patients with healthy replacement tissue.
It was incredibly difficult, but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural, gut, muscle and bone cells. The process still can’t be controlled, and may have unforeseen limitations; but if efforts to understand and master stem cell development prove successful, doctors will have a therapeutic tool of incredible power.
The same applies to cloning, which is really just the other side of the coin. True cloning, as first shown with the sheep Dolly two years ago, involves taking a developed cell and reactivating the genome within, resetting its developmental instructions to a pristine state. Once that happens, the rejuvenated cell can develop into a full-fledged animal, genetically identical to its parent.
For agriculture, in which purely physical characteristics like milk production in a cow or low fat in a hog have real market value, biological carbon copies could become routine within a few years. This past year scientists have done for mice and cows what Ian Wilmut did for Dolly, and other creatures are bound to join the cloned menagerie in the coming year.
Human cloning, on the other hand, may be technically feasible but legally and emotionally more difficult. Still, one day it will happen. The ability to reset body cells to a pristine, undeveloped state could give doctors exactly the same advantages they would get from stem cells: the potential to make healthy body tissues of all sorts, and thus to cure disease. That could prove to be a true "miracle cure".

Smart Exercise
Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developed. Dr. Cameron claims this allows people who exercise to concentrate better. As she says: "While we already know that exercise is good for the heart, exercise can literally cause physical changes in the brain."
The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. With babies, even a little movement can show big results. Margaret Barnes, a pediatrician (儿科医师), believes in the importance of exercise. She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses. They need to establish a connection between motion and memory. In this way, as they get older, children will begin to associate physical activity with higher learning, " says Margaret.
Older people can beef up their brains as well. Cornell University studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for infants, exercise for older people should involve some complexity. Learning some new skills or motions helps to open up memory paths in the brain that may not have been used for a long time.
For most people, any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain’s flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.
To be beneficial, exercise for older people should

A:be done in a group. B:be done on a daily basis. C:involve great difficulty. D:increase the heart rate.
