新素养·学习能力 Have you always thought that kids are smarter than adults? You'd be right—at least when it comes to learning new things.
New research shows that kids do get new knowledge and learn new skills faster than grown-ups. It all comes down to something in the brain(大脑) called GABA, which helps newly learned material stick in the brain. Researchers have found GABA levels increase quickly in the brains of children of primary school age while they are learning new tasks or information. However, GABA levels in the brains of grown-ups, aged 18 to 35, don't change during or after lessons in new tasks and information.
"Our results show that children of primary school age can learn more within a given period of time than grown-ups," said Takeo Watanabe, a professor(教授) at Brown University in the US.
Dr Sebastian Frank, from the University of Regensburg in Germany, said their findings agreed with the common opinion that children outperformed grown-ups in their learning abilities. "GABA plays a key role in making learning efficient(效率高的)," added Dr Frank.
The researchers suggested teachers and parents should give children as many chances as possible to develop(发展) new skills, from learning the times table to riding a bike. Professor Watanabe said the findings could also be used to help adults learn more efficiently. "For example, a new technology or therapy(疗法) could be developed to increase the level of GABA in the brains of grown-ups."

答案
1. A 图示理解题。根据第二段“Researchers have found GABA levels increase quickly in the brains of children of primary school age while they are learning new tasks or information. However, GABA levels in the brains of grown-ups, aged 18 to 35, don't change during or after lessons in new tasks and information.”可知，研究人员发现，小学学龄的儿童在学习新任务或新信息时，大脑中的GABA水平会迅速上升。然而，18至35岁的成年人大脑中的GABA水平在学习新任务和新信息期间或之后不会发生变化。所以A选项的图片正确展示了儿童和成人在学习新事物时GABA水平的变化情况。故选A。
2. B 词义猜测题。根据第三段“Our results show that children of primary school age can learn more within a given period of time than grown-ups”可知，研究的结果是小学学龄的儿童在一定时间内比成年人学习得更多。所以这里表示儿童的学习能力优于成年人。故选B。
3. D 细节理解题。根据“The researchers suggested teachers and parents should give children as many chances as possible to develop new skills, from learning the times table to riding a bike.”可知，应该给孩子们更多的机会学习新技能。故选D。
＞＞ 直接理解题
4. C 文章主旨题。根据“Have you always thought that kids are smarter than adults? You'd be right—at least when it comes to learning new things.”以及全文可知，整篇文章都在告诉我们“孩子学新东西比成年人快的原因”。故选C。
