Shortly after the British naturalist, Charles Darwin, published his theory of evolution, a Victorian lady was asked what she thought of the idea that humans and animals were descended from a common ancestor. "Let us hope it is not true," she said. (46)
This story is probably apocryphal, but it illustrates well the attitudes of the time. (47) Many people accept Darwin's view of how we came into being that our bodies evolved through the process of natural selection acting on our genes.
However, Darwin believed evolution was responsible for far more than just our physical characteristics. He saw it as the major influence in shaping our psychology. In- deed, he predicted that "in the distant future, psychology will be based on a new foundation". (48)
To proponents of concepts like free will and personal responsibility, such an idea seems absurd. (49) Their research has revealed increasing evidence that the human mind is made up of innate mechanisms, which control everything from the way we perceive time and space, to how we learn survival techniques and choose mates.
(50) Steven Pinker, Professor of Cognitive Science at the Massachusetts Institute of Technology, likens language ability to computer software, "children learn a new word every 90 minutes of their waking life for years, then they have to figure out how to string them together using a kind of mental computer program. The essence of human language is the ability to convey new ideas by putting words together in different combinations. Since we all have this language 'software' in our minds, we can figure out what others are saying by the meanings of the words and the order in which they are arranged."
A. Today, we are more comfortable with out past.
B. "And, if it is true, let us hope it does not become public knowledge."
C. But a growing number of scientists are questioning the extent to which our behavior. is controlled by our culture.
D. Many people are calling for controls on cloning immedicte1y before the practice is abused.
E. The foundation was, of course, his theory of evolution.
F. Nowhere is this more obvious than our innate ability to learn languages.

Before high school teacher Kimberly Rugh got down to business at the start of a recent school week, she joked with her students about how she'd had to clean cake out of the corners of her house after her 2-year-old son's birthday party. This friendly combination of chitchat took place not in front of a blackboard but in an, E-mail message that Rugh sent to the 145 students she's teaching at the Florida Virtual School, one of the nation's leading online high schools. The school's motto is "any time, any place, any path, any pace."
Florida's E-school attracts many students who need flexible scheduling, from young tennis stars and young musicians to brothers Tobias and Tyler Heeb, who take turns working on the computer while helping out. with their family's clam-farming business on Pine Island, off Florida's southwest coast. Home-schoolers also are well represented. Most students live in Florida, but 55 hail from West Virginia, where a severe teacher shortage makes it hard for many students to take advanced classes. Seven kids from Texas and four from Shanghai round out the student body.
The great majority of Florida Virtual Schoolers—80 percent—are enrolled in regular Florida public or private high schools. Some are busy overachievers. Others are retaking classes they barely passed the first time. The school's biggest challenge is making sure that students aren't left to sink or swim on their own. After the school experienced a disappointing course completion rate of just 50 percent in its early years,Executive Director Julie Young made a priority out of what she calls "relationship-building," asking teachers to stay in frequent E-mail and phone contact with their students. That personal touch has helped. The completion rate is now 80 percent.
Critics of online classes say that while they may have a limited place, they are a poor substitute for the face-to-face contact and socialization that take place in brick-and-mortar classrooms. Despite opportunities for online chats, some virtual students say they'd prefer to have more interaction with their peers.
Students and parents are quick to acknowledge that virtual schooling isn't for everyone. "If your child's not focused and motivated, I can only imagine it would be a nightmare," says Patricia Haygood of Orlando, whose two daughters are thriving at the Florida school. For those who have what it takes, however, virtual learning fills an important niche. "I can work at my own pace, on my own time," says Hackney. "It's the ultimate in student responsibility."
Kimberly Rugh Talked about her son's birthday party ______ .
A.with her friends
B.with her colleagues
C.in the classroom
D.in an E-mail massage sent to her students

As was reported that there was an accident at a corner of the Roman Street in this morning. A car ran into a truck and fortunately, nobody got injured. Who will be responsible for an accident is still under investigation. What the police should do now is that they must find out what led the accident. They said it was difficult of them to judge because how the accident happened was not clear. Perhaps the reason was that the driver was too tiring to stop the car in time. The driver didn't admit the fact that he is driving too fast at the turning. The police doubted that what he said was true and decided to make a farther investigation.
