Babies who are slow to gain weight in the first months of their lives generally catch up to their peers by age 13,a large UK study shows, Researchers said the results would make parents whose babies fail to put on weight quickly less worried.
The researchers looked at data from ,11,499 children who took part in a large study, It showed that 507 who were slow to gain weight in the first eight weeks of life recovered fairly quickly and had almost caught up by age 2. Another group of 480 who were slow to gain between eight weeks and nine months continued to put on weight slowly until they were seven years ,but then had a sudden increase and caught up by age 13, The different pattems of recovery between the two groups were likely due to different reasons for slow weight gain ,the researchers said, All the children were still lighter and shorter than their peers by the time they were teenagers ,but within the normal range.
The findings highlight the importance of monitoring a baby’s weight and height gain during the first few weeks and months ,but not creating anxiety with parents of slow-growing babies, said the study leader Prof Alan Emond from the University of Bristol.
“In the past, a lot of parents have been caused unnecessary anxiety by heaith professionals and this is a positive and reassuring message.”He said in many cases of slow growth where children do not follow the standard’curve’(曲线)it is just because they are following their genetic potential.
Dr Simon Newell, vice-president of the Royal College of Paediatrics and Child Health, said he broadly agreed with the concluslons of the researchers but stressed that poor weight gain was something that needed to be monitored closely, “I would encourage parents to use growth charts but if measurements show your baby is smaller than averager it may be completely normal, ”he said.
1.What can we know from the findings of the research?
A、All the cases of slow weight gain in the first months of the babies’ lives are caused by the same reason
B、Slow-growing babies will have the same height and weight with their peers by age13
C、Many cases of children whose growth don’t meet the growing standard curve cannot be treated as abnormal

The research carried out by the University of Bari in Italy could help prove hospitals who are accused of wasting money on art and decoration as it suggests a pleasant environment helps patients ease discomfort and pain.
A team headed by Professor Marina de Tommaso at the Neurophysiopathology Pain Unit asked a group of men and women to pick the 20 paintings they considered most ugly and most beautiful from a selection of 300 works by artists such as Leonardo da Vinci and Sandro Botticelli. They were then asked to look at either the beautiful paintings, or the ugly painting, or a blank panel while the team zapped(照射) a short laser pulse at their hand, creating a sensation as if they had been stuck by a pin. The subjects rated the pain as being a third less intense while they were viewing the beautiful paintings, compared with when looking at the ugly paintings or the blank panel. Electrodes measuring the brain's electrical activity also confirmed a reduced response to the pain when the subject looked at beautiful paintings.
While distractions, such as music, are known to reduce pain in hospital patients, Prof de Tommaso says this is the first result to show that beauty plays a part.
The findings, reported in New Scientist, also go a long way to show that beautiful surroundings could aid the healing process.
"Hospitals have been designed to be functional, but we think that their artistic aspects should be taken into account too," said the neurologist. "Beauty obviously offers a distraction that ugly paintings do not. But at least there is no suggestion that ugly surroundings make the pain worse. " "I think these results show that more research is needed into the field how a beautiful environment can alleviate suffering."
Pictures they liked included Starry Night by Vincent Van Gogh and Botticelli’s Birth of Venus. Pictures they found ugly included works by Pablo Picasso, the Italian 20th century artist Anonio Bueno and Columbian Fernando Botero. "These people were not art experts so some of the pictures they found ugly would be considered masterpieces by the art world," said Prof de Tommaso.
1.The underlined word “alleviate” in the fifth paragraph probably means “_________”.
A. cure B. ease C. improve D. kill
2.How many artists have been mentioned in the passage?
A. 4. B. 5. C. 6. D. 7.
3.Which of the following is TURE about the view of Prof de Tommaso’s?
A. Beautiful surroundings could help to heal sufferings completely .
B. Hospitals must take their artistic aspects into consideration first.
C. Ugly surroundings will surely make the pain worse.
D. Both music and beauty can reduce pain in hospital patients.
4.Which of the following is the suitable title for the passage?
A. Beautiful surroundings can ease pain.
B. Ugly paintings could be masterpieces.
C. More research should be done in the field.
D. Latest environmental research.
American researchers found females are the more talkative sex because of a special “language protein(蛋白质)” in the brain.
The study, conducted by neuroscientists （神经学家）and psychologist from the University of Maryland, concluded that women talked more because they had more of the Foxp2 protein. The research, published in the Journal of Neuroscience, found that higher levels were found among humans that were women but in rats that were males. Their findings came after it was previously claimed that ladies speak about 20,000 words a day – over 13,000 more than men. "This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Prof Margaret McCarthy, who led the study. In their study, the researchers attempted to determine what might make male rats more vocal than their female friends.
They separated four-day-old rats from their mothers and then counted the number of times they cried out in the “ultrasonic range”, the frequencies higher than humans can hear, over five minutes. While both sexes called out hundreds of cries, the males called out twice as often, they found. But when the pups were returned to their mother’s cage, she fussed over her sons first. Tests conducted on the parts of the brain known to be associated with vocalcalls showed the male pups have up to twice as much Foxp2 protein as the females. The researchers then increased the production in the brains of female pups and reduced it in males. This led to the female rats crying out more often and their mothers showing more interest to them. In contrast, males became less “talkative”.
The researchers then tested samples from ten children, aged between three and five, which showed that females had up to 30 per cent more of the Foxp2 protein than males, in a brain area key to language in humans.
“Based on our observations, we assume higher levels of Foxp2 in girls and higher levels of Foxp2 in male rats is an indication that Foxp2 protein levels are associated with the more communicative sex,” said Prof McCarthy.
"Our results imply Foxp2 as a component of the neurobiological basis of sex differences in vocal communication in mammals."
1.From the second paragraph, we can learn that ________.
A．women always speak more words than men
B．men and male rats have low levels of language protein
C．women and male rats have similar levels of Foxp2
D．McCarthy isn’t the first to find females more talkative
2.The underlined phrase “fussed over” in the third paragraph probably means______.
A．paid attention to B．related to C．put pressure on D．counted on
3.The researchers carried out the experiments on rats in order to _______.
A．test which part of the brain is key to language in rats and humans
B．prove the levels of Foxp2 protein in humans and rats are different
C．determine the reason why female rats are more talkative than male rats
D．discover the association between Foxp2protein and vocal communication
4.Which of the following can be the best title for the passage ?
A．Tests on humans and rats B．Why women are the talkative sex
C．Sex differences in Foxp2 protein D．Foxp2 protein determines oral ability
While success is surely sweeter than failure, it seems failure is a far better teacher, and organizations that fail miserably often flourish (繁荣) more in the long run, according to a new study by Vinit Desai, assistant professor of management at the University of Colorado Denver Business School. Researchers have found that people missing their goals perform much better in the long run. That is because they gain more knowledge from their failures than their successes and the lessons are more likely to stay longer in their minds.
“We found that the knowledge gained from success was often fleeting while knowledge from failure stuck around for years,” said professor Desai, who led the study. “But companies often ignore failure. Managers may fire people or turn over the whole workforce while they should treat the failure as a learning opportunity.”
Prof Desai compared the flights of the space shuttle Atlantis and the Challenger. During the Atlantis flight last year, a piece of insulation (绝缘体) broke off and damaged the left solid rocket booster (助推火箭) but didn’t influence the program. There was little investigation. The Challenger was launched next and another piece of insulation broke off. This time the shuttle and its seven–person crew were destroyed. The disaster led to a major investigation resulting in 29 changes to prevent future disasters.
The difference in response in the two cases came down to this: Atlantis was considered a success and the Challenger a failure.
“Despite crowded skies, airlines are extremely reliable,” he said. “The number of failures is extremely small. And past researches have shown that older airlines, those with more experience in failure, have a lower number of accidents.”
Prof Desai doesn’t recommend finding out failure in order to learn. Instead, he advises organizations to analyze small failures to collect useful information rather than wait for major failures.
【小题1】 Why did experts pay little attention to the problem of Atlantis?
| A．Because it worked perfectly. |
| B．Because the right booster was still OK. |
| C．Because nothing serious happened then. |
| D．Because fewer people died in the flight. |
| A．their planes couldn’t fly high in the sky |
| B．they gained much from experience in failure |
| C．their planes were often checked by the experts |
| D．they were unpopular among passengers |
| A．show failure is a better teacher than success |
| B．explain why Challenger failed |
| C．introduce something about Prof Desai |
| D．tell managers how to achieve success |
| A．Giving definitions. |
| B．Making comparisons. |
| C．Analyzing causes. |
| D．Providing different examples. |
