When scientists set out to explore the roots of human laughter, some apes（类人猿） were just tickled（胳肢）to help. That’s how researchers made a variety of apes and some human babies laugh. After analyzing the sounds, they concluded that people and great apes inherited laughter from a shared ancestor that lived more than 10 million years ago. Experts praised the work, it gives strong evidence that ape laughter and human laughter are related through evolution（进化）.
Scientists have noted that apes make characteristic sounds during play or while being tickled, especially to signal that they’re interested in playing. It’s been suggested before that human laughter grew out of primate（灵长类动物） roots. But ape laughter doesn’t sound like human laughter. It may be slower noisy breathing. So what does that have to do with the human ha-ha? To investigate that, Marina Davila Ross and her colleagues carried out a detailed analysis of the sounds made by tickling three human babies and 21 other primates, apes included.
After measuring 11 features in the sound from each species, they tried to find out how these sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themselves are related, the scientists reported online in the journal Current Biology. They also concluded that while human laughter sounds much different from ape laughter, their typical features could have come from the same ancestor.
Panksepp, who studies laughter-like responses in animals but didn’t participate in the new work, called the paper exciting. Panksepp’s own work concludes that even rats produce laughter in response to playing and tickling, with sounds that can hardly be heard by people. Robert Provine, a scientist, who wrote the book, Laughter: A Scientific Investigation, said the new paper showed some important clues, like ape sounds that hadn’t been realized before.
69. Why did the scientists analyze the laughter made by tickling human babies and apes?
A. To try to discover if they can make characteristic sounds.
B. To see if they interested in playing.
C. To find out if the laughter of apes and humans is related.
D. To find out the differences between humans and apes.

“I was ___39___ at maths at school,” they say. “still am. Can’t ___40___ up to save my life. My little girl takes after____41___. Thinks take-aways are something to do with fish and chips. Ha-ha!” Oh, how we all laugh.

But how many of us remember it being ___42___ at the time? How many of us remember the blind panic of the Monday morning maths test when the ___43___ we could hope for was a miracle(奇迹) to make the numbers we ___44___ without thinking as answers somehow ___45___ the questions?

On the face of it, today’s children can ___46___ be considered happier and more satisfied. They have a daily numeracy lesson ___47___ to improving their maths skills. But if that sounds like hell to you, you may ___48__ find that your child surprises you by actually quite ___49__ it.

One of the __50___ is that over the last ten years or so, there has been a ___51___ in the way maths is taught. And many of those who teach it feel it’s been a ___52__ for the better.

Often the first question a teacher will ask is: can you do this in your___54___? And if they can, they do.

The whole approach is more___55___, the goal to get children understanding numbers, not just putting them through the uninteresting process of learning something by repeating it until they remember it.
