Researchers have found that being grateful isn’t just a nice personal quality that leads to good manners. I also leads to a great payoff. By being truly thankful for all that life provides, a child has more chance of being emotionally, and socially Successful.

“Gratitude opens your mind and lets you recognize the goodness in your life,” says Froh, a psychology professor who has conducted eight studios on gratitude over the past three years. According to Froh, a grateful child feels more connected and loved. After all, if he’s able to understand that many others care enough to make an effort for him, his life is improved. When older children aged 14 to 19 are able to acknowledge their good fortune, they’re more likely to be happy and experience lower levels of depression, envy and selfness.

For the past decade, experts like Froh have been conducting “gratitude interventions(干预)”, in which kids are encouraged to do a series of exercises, from writing a thank-you note to reciting it to make a gratitude journal, Overall, the results have been encouraging: Just in comparison with adults, it seems that children become more grateful.

Yet there remains much to be learned about children and gratitude. There’s some evidence suggesting that girls are more grateful than boys, Also, Froh says that while there’s not yet any hard data, there’s possibility that a child’s ability to be grateful depends on his or her age. One study looked at gratitude and life satisfaction in kids aged 3 to 9 and found that only 7 to 9-year-olds followed the example set by their parents in their ability to feel true gratitude. Most 3 to 6-year-olds don’t have the emotional development to see outside themselves enough to be truly grateful.

So how do people apply these newfound scientific findings? Froh encourages parents not to command children to express their thanks, but to let them show gratitude in whatever way is most comfortable. As Froh points out, children learn best when grown-ups model the very behavior they’d like to see in their kids.

1.What can we know about children who are grateful?

A.They are less likely to feel depressed.

B.They seem to be more thoughtful.

C.They feel proud of others’ good fortune.

D.They attach importance to selfness.

2.How do the experts conduct gratitude interventions?

A.By asking kids to do hard work.

B.By comparing kids with adults.

C.By guiding kids to follow good examples.

D.By encouraging kids to express their thanks.

3.What does Froh advise parents to do?

For the first time, researchers have discovered that some plants can kill insects in order to get additional nutrients. New research shows that they catch and kill small insects with their own sticky hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall to the ground.

Professor Mark Chase, of Kew and Queen Mary, University of London, said: “The cultivated (改良的) tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects.”

The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia（矮牵牛）, some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized.

It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil – and even various plants grown in your vegetable garden still have the ability.

The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: “We may be surrounded by many more murderous plants than we think.” “We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meat-eating plants," they added.

1.Tomatoes and potatoes kill insects to _____.

A. get more sticky hairs

B. make themselves grow better

C. make their roots stronger

D. avoid falling down to the ground

2.The word “carnivorous” in Paragraph 3 most probably means _____.

A. fast-growing

B. harmless

C. insect-killing

D. nutritious

3.The insect-killing technique of vegetables is developed most probably through _____.

A. evolution of species

B. helps from other garden plants

C. artificial cultivation

D. nutrients preserved in rich soil

4.The text is probably taken from _____.

A. a student book

B. a science fiction

C. a scientific repot

D. a bulletin board
