ear of corn. We placed the caterpillar in a glass fish tank with a metal mesh(网状物)cover for
its protection. We couldn’t be sure what type of leaves the caterpillar would eat, but as it had been
found in an ear of corn we decided to feed it leaves from particular garden vegetables.
Soon we began collecting information about the caterpillar and noticing changes. The children
wrote about what they saw in small groups. Three weeks into the caterpillar observation, the teacher
started a whole-group discussion going like this:
Teacher: “What do you notice about the caterpillar?”
Students: “It’s twice as big as when Edward brought it to the class.”
The students also commented that the caterpillar’s color had changed- yellowish and brownish
colors clearly appeared.
Teacher: “What do you think will happen next?”
Students: “I think it’s gonna make a cocoon(茧).”
Teacher: “Wait a minute! What do you mean? The caterpillar will become a cocoon?”
There was a considerable pause allowing the children to organize their thoughts and make a
prediction. At this point we took an informal survey showing more than half the class believed the
caterpillar would make a cocoon.
Then, to further our learning, we connected the research to literature by reading The Very Hungry
Caterpillar by Eric Carle(1969). This book presents a fictional account of the “transformation”
undergoing by a caterpillar: egg- larva- pupa- butterfly. When reading the book, the teacher used the
terms kids already knew like larva or pupa. She also pointed out an error in the book, moths have
cocoons and butterflies have chrysalides(蝶蛹).
Eventually, it developed a cocoon, which lay unnoticed for a week as the children had become
distracted by other activities and events in our school and classroom. One day, the class noticed an
open “case” with the contents gone. The children decided the caterpillar had “finished growing” and
had changed into a butterfly or a moth. They guessed the creature had managed to escape through
a tear in the mesh cover of the tank and found its way to a nearby park where there were many trees
and some gardens. All these conjectures seemed reasonable and were supported by the teacher.
B. where it tended to make its way
C. where it had been found
D. what they had learned from watching it
B. Size.
C. Form.
D. Behavior.
B. guesses
C. statistics
D. elements
B. Animal Protection
C. An Amazing Caterpillar
D. An interesting Experience

NEW YORK (AP) — In a report, the Pew Internet and American Life Project said 47 percent of U.S. adult Internet users have looked for information about themselves through Google or another search engine.
That is more than twice the 22 percent of users who did in 2002, but Pew senior research specialist Mary Madden was surprised that the growth wasn’t higher than it had been expected.
“Yes it’s doubled, but it’s still the case that there’s a big chunk of Internet users who have never done this simple act of connecting their names with search engines,” she said. “Certainly more and more people have become aware of this, but I don’t know it’s necessarily kept pace with the amount of content we post about ourselves or what others post about us.”
About 60 percent of Internet users said they aren’t worried about the extent of information about themselves online, although they are increasingly concerned over how that data can be used.
Americans under 50 and those with more education and income were more likely to self-Google---in some cases because their jobs demand a certain online persona(形象).
Meanwhile, Pew found that 53 percent of adult Internet users admit to looking up information about someone else, famous people not included.
Often, it’s to find someone they’ve lost touch with. But looking up information about friends, relatives, colleagues and neighbors also was common.
Although men and women equally searched for online information about themselves, women were slightly more likely to look up information about someone they are dating.
In many cases, the search is not harmful, done to find someone’s contact information. But a third of those who have conducted searches on others have looked for public records, such as bankruptcies(破产) and divorce proceedings. A similar number have searched for someone else’s photo.
Pew also found that teens were more likely than adults to limit the range of people who can see their information at an online hangout like Facebook or News Corp.’s MySpace, contrary to conventional wisdom.
“Teens are more comfortable with the applications in some ways, (but) I also think they have their parents and teachers telling them to be very careful about what they post and who they share it with,” Madden said.

The Pentagon(五角大楼), headquarters of the Department of Defense in US, is one of the world's largest office buildings. It is twice the size of the Merchandise Mart in Chicago, and has three times the floor space of the Empire State Building in New York. There are very few people throughout the United States who do not have some knowledge of the Pentagon. Many have followed news stories coming from this building. However, relatively few people have had the chance to visit it.
The Pentagon is in fact a city in itself. About 23,000 employees, both soldiers and other people, contribute to the planning of the defense of the country. These people arrive daily from Washington, D.C. and around over about 30 miles of highways, including express bus lanes(快车道) and one of the newest subway system in the country. They ride past 200 acres of grass land to park about 8,770 cars in 16 parking lots; climb 131 stairways or take 19 lifts to reach offices that occupy 3,705 square feet. While in the building, they tell time by 4,200 clocks, drink from 691 water taps, make use of 284 rest rooms, use up 4,500 cups of coffee, 1,700 pints of milk and 6,800 soft drinks prepared or served by a restaurant of 230 persons and distributed(分散于) in 1 dining room, 2 cafeterias, a snack bars, and an outdoor snack bar.
The building itself is an extraordinary structure. Built during the early years of World War II, it is still thought of as one of the most efficient buildings in the world. In spite of 17.5 miles of corridors(走廊) it takes only seven minutes to walk between any two points in the building.

Head held high, hands firmly gripping her walker, Mary Arnott, 99, walks slowly with dignity through the women’s changing room at the Etobicoke Olympium pool, past the teenage girls who have been blow-drying their hair for half an hour, into the mist of the showers, then out the door and first one into the heated pool. She jumps over to the shallow end, stopping to talk to friends—everyone knows Arnott here;she swims twice a week and treats it as a job—about their children, the viciousness(谬误)of bridge and their health.
In fact, Arnott is an exception to the exception. Not only has she lived 20 years past the average lifespan for Canadians, she’s healthy, her mind is sharp and she lives independently.
Born in Brooklyn on May 28, 1909, Arnott was raised on Staten Island. She survived scarlet fever(猩红热), helped bring up four siblings(兄弟姐妹)after her mother died in 1923 and worked as a secretary in New York City for 12 years, earning$35 a week and a$150 bonus at Christmas.
Now she’s happy living in a one-room apartment with a kitchen and a bathroom in her daughter’s house. She wears a hearing aid, does the cryptic crossword(有隐义的纵横字谜)with a magnifying glass, and can’t really explain why she has lived so well so long.
Until recently, she has still liked to drink red wine—she used to drink two glasses before supper each day. It’s more likely genes, she admits. Her interest in other people and life in general may have had something to do with it. Asked if a star photographer can take her picture at the pool, Arnott seems cheerful.
“I look good in a swimsuit, ” she says, nodding her head firmly. “I look better in a swimsuit than I do in pants. ”
