请认真阅读下面短文,从短文后各题所给的A、B、C、D四个选项中,选出最佳选项,并在答题卡上将该项涂黑。

What is it about maths, anyway? Why is it that a ___36___ who would rather die than ___37___ they found reading difficult at school will happily say he is brain-dead when it ___38___ to numbers?

“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.

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. There’s generally much more emphasis now on __53___ arithmetic, getting children used to doing calculations without forever having a pen in one hand and a calculator in the other. 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.
