They 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.

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

A. sense of hearing.

D. sense of smell.

A. the size of cards.

B. the colour of pictures.

C. the shape of patterns.

D. the number of objects.

62. 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.

63. Where does this text probably come from?

A. Science fiction.

B. Children’s literature.

C. An advertisement.

D. A science report.

Hundreds of people lined up at Grand Central Terminal yesterday, but they weren’t there to catch a train. They came to New York City’s famous railroad station to trade in old dollar bills for the new George Washington Presidential $ 1 coin.

The gold-colored coin is the first in a new series by the U.S. Mint（造币厂）that honors former U.S. Presidents. The Mint will issue four Presidential $ 1 coins a year through 2016. Like the popular 50 State Quarters(纪念币) program, which issues coins in the order in which each state joined the Union, Presidential $ 1 coins will come out in the order in which each President served. The George Washington coin is the first to be released. John Adams, Thomas Jefferson and James Madison coins will come out later this year.

The Presidential $ 1 coins will be the same size and color as the Sacagawea Golden Dollar. However, there is an important difference. For the first time since the 1930s, there is an inscription（题字）on the edge of each coin. Each coin will show a different President on its face, or head side. It will also show the President’s name, the order in which he served and his years in office. The other side of the coin will show the Statue of Liberty and the inscriptions “United States of America” and “$ 1”.

There will be one Presidential $ 1 coin for each President, except Grover Cleveland. He will have two! Cleveland is the only U.S. President to have served two nonconsecutive（不连续的）terms.

The last President scheduled to get a coin is Gerald Ford because a President must have been dead for two years before he can be on a coin.
