New York (Reuters) --- Television can act like a painkiller when it comes to children and is more effective than a mother’s comforting, according to a small Italian study.

The University of Siena study, published in Archives of Disease in Childhood, was based on 69 children aged 7 to 12 who were divided into three groups to have blood taken.

One group was given no distraction while the blood was being taken. Meantime mothers of children in the second group attempted to distract the youngsters by talking to them, soothing(安慰), and/or caressing them.

In the third group, the children were allowed to watch television cartoons while the procedure was being carried out.

After the samples were taken, the children and their mothers rated their pain scores.

The children recording the highest pain scores were in the group getting no distraction. These scores were about three times as high as those recorded by children allowed to watch the cartoons.

Children comforted by their mothers recorded middling scores.

On average, the mothers rated pain scores higher than the children but they also recorded the lowest pain scores for children who had been allowed to watch television.

“The higher pain level reported by children during mothers’ efforts at distraction shows the difficulty mothers have in interacting positively at a difficult moment in their children’s life,” the researchers said in their report.

They added that watching television also seemed to increase children’s pain tolerance(容忍力).

64. If children are concentrated while having their blood taken, they will _______.

A. feel no pain                   B. record the lowest pain scores

C. record the highest pain scores     D. feel less pain

65. According to the Italian study, children who are suffering from pain had better _______.

A. get comfort from their mothers    B. watch cartoons on TV

C. read picture books              D. get no distraction

66. The underlined word “distract” in the third paragraph probably means “_______.”

A. reduce one’s pain              B. get one’s attention away

C. help one get concentrated        D. give comfort to

67. From the passage, we can infer that _______.

A. mothers can soothe their children greatly at hard moments

B. mothers’ love and comfort is the best medicine for children

C. children can have their pain tolerance increased by mother’s efforts

D. mothers’ comfort does not reduce much of their children’s pain

“我长小弟三岁。从我有比较完整的记忆起,生活里便有我的弟弟,一个胖胖的、可爱的小弟弟,跟在我身后。他虽然小,可是在玩耍时,他常常当老师,照顾着小朋友,让大家坐好,他站着上课,那神色真是庄严。他虽然小,在昆明的冬天里,孩子们都生冻疮,都怕用冷水洗脸,他却一点不怕。他站在山泉边,捧着一个大盆的样子,至今还十分清晰地在我眼前。“小姊,你看,我先洗!”他高兴地叫道。”
