The baby is just one day old and has not yet left hospital. She is quiet but alert (警觉). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus - until a third, with three black spots, is presented. Her gaze returns; she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?

Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects(a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise(同样地) when the researchers started with drumbeats and moved to spots.

1.The experiment described in Paragraph 1 is related to the baby’s ______.

A.sense of hearing.

B.sense of sight.

C.sense of touch.

D.sense of smell.

2.Babies are sensitive to the change in ______.

A.the size of cards.

B.the colour of pictures.

C.the shape of patterns.

D.the number of objects.

3.Why did the researchers test the babies with drumbeats?

A.To reduce the difficulty of the experiment.

B.To see how babies recognize sounds.

C.To carry their experiment further.

D.To keep the babies’ interest.

4.Where does this text probably come from?

A.Science fiction.

B.Children’s literature.

C.An advertisement.

D.A science report.

Los Angeles June 14, 2006 – Hollywood actress Daryl Hannah was arrested yesterday after spending two weeks sitting in a walnut tree on an urban farm a few kilometers from downtown Los Angeles. She was one of 40 people, including celebrities from the music and movie world, who were protesting at the proposed destruction of the 14 – acre farm. Police officers cut away branches from the tree and used a fire engine to reach Ms Hannah and her co – protester, environmentalist John Quigley. The two of them raised their fists in defiance(反抗)as they were removed.
Protesters, some of whom had chained themselves to concrete –filled barrels(桶),said that it was essential to keep the farm operating, as it provided food for hundreds of poor families in the area. About 350 people grow produce and flowers on the farm, which has been there for more than a decade and is situated in an inner –city area surrounded by warehouses and railroad tracks. However, the local authority recently approved plans for the area to be cleared and redeveloped for the construction of a huge new warehouse.
Ms Hannah, 45, star of films such as Splash and Kill Bill was not thrilled about being arrested. “But I felt it was important to show my support for the people,” she said. “This farm should be a model for sustainable (可持续的) urban agriculture. It needs to be replicated, not eradicated.”
The record length for a tree protest is held by a woman called Julia Hill, who remained on top of a 30-metre-high redwood tree in Northern California for 738 days from December 1997 to December 1999. She was successful in saving the tree and those around it from destruction. Ms Hill was also at the Los Angeles urban farm project this week, but her presence failed to stop the inevitable (不可避免的). No sooner had the protesters been removed than earth-moving machines moved in and began to clear the land.
