Ask why most people are right-handed,
and the answer might fall along the same lines as why fish school(鱼成群地游). Two
neuroscientists suggest that social pressures drive individuals to coordinate
their behaviors so that everyone in the group gets an evolutionary
edge. Approximately 85 percent of people prefer their right hand, which is controlled by the left hemisphere of the brain. One theorized benefit of locating a particular function in one hemisphere is that it frees the other to deal with different tasks. But that idea does not explain why. population-wide trends for handedness exist in the first place. Moreover, evidence gleaned in recent years has overturned the long-held belief that human handedness is a unique by-product of brain specialization attributable to language. A suite of studies has revealed brain lateraliz A. it was a necessary evolutionary process B. it has something to do with human right-handedness C. they need to coordinate with other fish D. their brain function is unique [单项选择]
Now, you want to know about life in the past. Right I can tall you. When I was a boy, things were different. I had to get up at six every morning, That was not very bad in summer, but in winter it was cold. And we didn’t have any hot water in the house. We had to wash in cold water. My dad had some chickens. I had to feed them every morning and then I had to go to school on foot with my little sister. It was two miles to school and two miles back in the evening.

On Sundays we had to go to church three times-morning, afternoon and evening. And we couldn’t play outside on Sundays. But it wash’t all bad. We had some good times. We could go out and our parents didn’t have to worry about us. There weren’t so many cars on the roads then, so the streets were safe to play in. And there were no 我来回答: 提交
