Turtles may be cute, but they are also slow and clumsy, which doesn’t really help them when they are trying to cross train tracks. Luckily, for the turtles in Japan’s Hyōgo Prefecture, railway operators and a local aquarium teamed up to find a solution.

Between 2002 and 2014,　 disruptions (中断) of train operation caused by turtles were reported 13 times, with many more probably going unreported. That is why, in 2015, West Japan　 Railway Co. and Suma Aqualife Park in Kobe joint forces to prevent tragic turtle deaths on the　 tracks and unnecessary train delay. After running a series of tests and experiments, they came up with a U-shaped ditch (沟渠 ) that collects the turtles, preventing them from getting stuck between the metal tracks and getting crushed to death.

Tests showed that turtles trying to cross the train tracks often fall into the space between them, which leaves them with no other option than to walk between them. Sadly, this causes some of them to get stuck between the metal tracks at junctions（交叉口）, and they unavoidably get crushed to death when the points blades（叶片）move.

“The turtles are basically just going about their daily business and have to cross the lines to　 get to a pond,” a railway spokesperson said. “When the points blades move, unfortunately they　 get squashed between them and die. They can cause long delays to operations so we consulted with a turtle specialist to find the best way to help them.”

The U -shaped concrete ditches installed at several critical points along the train lines near the city of Kobe catch the turtles at danger of getting stuck between the tracks. They allow the turtles to get past the junctions safely. 10 turtles were reportedly saved in the first month since the U-shaped ditch was put to use in November 2015.

They may be small and not able to speak, but babies are proving their amazing cleverness. Scientists began finding infants’ skills are more than they are supposed to be.

_________

Speaking of music, babies can’t seem to resist it. Not only are their ears turned to the beats, babies can actually dance to the music.

To test babies’ dancing ability, the researchers played recordings of classical music, rhythmic beats and speech to infants, and recorded the results. They also invited professional dancers to analyze how well the babies matched their movements to the music. The babies moved their arms, hands, legs feet and heads in response to the music, much more than to the speech. The finding suggests this dancing ability is innate(与生俱来的) in humans, though the researchers aren’t sure why it becomes weaker later in their life.

Learning Quickly while Sleeping

Babies can learn even while asleep, according to a 2011 study. In experiments with 26 sleeping infants, each just 1 to 2 days old, scientists played a musical tone followed by a puff of air to their eyes 200 times over the course of a half-hour. 124 electrodes(电极) stuck on the head and face of each baby recorded brain activity during the experiments. The babies rapidly learned to foretell a puff of air upon hearing the tone, showing a four-time increase on average in the chances of tightening their eyelids in response to the sound by the end of the experiments.

As newborns spend most of their time asleep, this newfound ability might be crucial to rapidly adapting to the world around them and help to ensure their survival, researchers said.

Judging Characters Well

Judging another person helpful or harmful is crucial when choosing friends. And that ability starts early. Kiley Hamlin of Yale University showed both 6-and 10-month-olds a puppet(木偶) show, in which one character helped another climb a hill. In another scene a third character pushed the climber down. The little ones then got to choose which character they preferred. For both age groups, most babies chose the helper character. This character-judging ability could be baby’s first step in the formation of morals, Hamlin thought.

1.Which of the following subtitles can fill in the underlined blank?

2.The underlined word “it” in the third paragraph refers to______.

3.The experiment with 26 sleeping infants prove that_______.

4.In the last experiment, most babies chose the helper character, showing that________.
