【题目】 It is a question that has confused parents for many years: why do children refuse to eat greens?

Now, two American experts believe they have the answer.

After studying dozens of babies as they played with various objects, the researchers noted that they were far more unwilling to touch plants than other things. They believe this is because evolution (生物进化) has biologically made children be wary of plants.

Due to susceptibility (敏感性) to illness or injury in the early years of life, the body has designed an inner defence mechanism (内部保护机制) that limits a child’ s contact with plants, they think. The researchers believe this is why children turn their noses up when faced with a plate of broad beans.

The findings are published in a paper by Dr. Annie E Wertz and Dr. Karen Wynn, both psychologists at Yale University.

They wrote, “Throughout human evolution... plants have been important in human’s life. Yet, for all of these benefits, plants have always caused very real dangers.”

“Plants produce toxins (毒素) as defences that can be harmful, or even deadly. Some plants also produce physical defences, such as thorns (荆棘) can damage tissues (组织) and cause effects over the whole body.”

They added, “We predicted that babies may have behavioural strategies that reduce dangers caused by plants.”

To test their theory, the researchers studied how children aged eight to 18 months old reacted when presented with a variety of objects. It took much longer for children to grab plants; objects that were pretended to look like plants also caused a slow response time.

For parents attempting to spoon some peas into the mouth of their child, this finding should come as welcome relief.
