The students felt proud of Helios because . A. it could run as far as 350 miles B. it was favored by many children C. it had high-quality batteries D. it was driven by clean energy 04北京D Grown-ups know that people and objects are solid. At the movies, we know that if we reach out to touch Tom Cruise, all we will feel is air. But does a baby have this understanding? To see whether babies know objects are solid, T. Bower designed a method for projecting an optical illusionof a hanging ball. His plan was to first give babies a real ball, one they could reach out and touch, and then to show them the illusion. If they knew that objects are solid and they reached out for the illusion and found empty air, they could be expected to show surprise in their faces and movements. All the 16-to 24- week -old babies tested were surprised when they reached for the illusion and found that the ball was not there. Grown-ups also have a sense of object permanence. We know that if we put a box in a room and lock the door, the box will still be there when we come back. But does a baby realize that a ball that rolls under a chair does not disappear and go to never-never land? Experiments done by Bower suggest that babies develop a sense of object permanence when they are about 18 weeks old. In his experiments, Bower used a toy train that went behind a screen. When 16-week-old and 22-week-old babies watched the toy train disappear behind the left side of the screen, they looked to the right, expecting it to reappear. If the experimenter took the train off the table and lifted the screen, all the babies seemed surprised not to see the train. This seems to show that all the babies had a sense of object permanence. But the second part of the experiment showed that this was not really the case. The researcher substituteda ball for the train when it went behind the screen. The 22-week-old babies seemed surprised and looked back to the left side for the train. But the 16-week -old babies did not seem to notice the switch. Thus, the 16-week-old babies seemed to have a sense of “something permanence, while the 22-week-old babies had a sense of object permanence related to a particular object. 查看更多

  It’s not the flashiest car in the world.Not even close.But the 1971 Volkswagen named Helios can do something most cars can’t :run on solar energy-energy from the sun’s light and head!

  Joshua Bechtold, 14,and the other students at the Riverside School in Lyndonville, Vermont, worked many months to get Helios ready.They named their car after Helios, the sun god in Greek mythology(神话).

  A teacher drove Helios, but the children talked with people wherever they stopped along the road.“That was my favorite part,” says Anna Browne,15.“We explained how the car runs.”

  Due in part to old, inefficient batteries(电池),Helios finished fourth-out of four-in its kind, the sun-powered class.“We were there for the fun of it,” Anna says, “We’re proud of Helios,”says Ariel Gleicher, 14.“It’s a car that’s good for the environment.”
