And experts say that as adults they have a higher risk of diseases including heart disease and diabetes. The World Health Organization1 estimates that every year twenty million babies are born with low birth weight. Nine out of ten of them are born in developing countries. 欖閾團(tuán)皺鵬緦壽驏頦蘊(yùn)釙負(fù)壽虜餉駒。The new study took place in Dar es Salaam.4,200 pregnant women received multivitamins. The pills contained all of the vitamins in the B group along with2 vitamins C and E. They also contained several times more iron and folate than the levels advised for women in developed nations. Pregnant women especially in poor countries may find it difficult to get enough vitamins and minerals from the foods in their diet. 遜輸吳貝義鰈國鳩猶騸繢樣餃鱉饒禿。The scientists pared the findings with results from a group of4,000 women who did not receive the vitamins. A report by the scientists, from the United States and Tanzania, appeared in the New England Journal of Wafaie Fawzi of the Harvard University School of Public Health4 led the study. None of the women in the study had , the virus that causes The scientists reported earlier that daily multivitamins were a lowcost way to reduce fetal deaths in pregnant women infected with7 .

Just under eight percent of the babies born to women who took the multivitamins weighed less than2,500 grams. The rate was almost nine and onehalf percent in the group of women who received a placebo, an inactive pill, instead of the vitamins. But the vitamins did not do much to reduce the rates of babies being born too early or dying while still a fetus. Still, the researchers say multivitamins should be considered for all pregnant women in developing countries. 誦終決懷區(qū)馱倆側(cè)澩賾鱺罷礙鋮飴盜。詞匯：multivitamin n. 多種維生素制劑urge v. 極力主張；強(qiáng)烈要求；敦促pregnant adj. 懷孕的，妊娠的Tanzania n. 坦桑尼亞（非洲）diabetes n. 糖尿病，多尿癥Dar es Salaam n. 達(dá)累斯薩拉姆（坦桑尼亞首都）folate n. 葉酸鹽mineral n. 礦物質(zhì)；無機(jī)鹽 adj. 礦物質(zhì)的；無機(jī)的fetal adj. 泰的，胎兒的lymphocyte n. 淋巴細(xì)胞immunity n. 免疫力；免疫性infection n. 傳染，感染；傳染病placebo n. 安慰劑；安慰劑治療inactive adj. 無作用的pilln. 藥丸，丸劑fetus n. 胎，胎兒注釋：World Health Organization (WHO)：世界衛(wèi)生組織along with：與…一起New England Journal of Medicine：新英格蘭醫(yī)藥雜志。New England 是美國東北六州( Maine, Vermont, New Hampshire, Massachusetts, Rhode Island 和 Connecticut )的總稱。醫(yī)滌侶綃噲睞齒辦銩凜贗囂審慶飼頗。4.

In an experiment that exposed healthy volunteers to a cold or flu virus,3 researchers found that people with a generally sunny disposition4 were less likely to fall ill. 嬤鯀賊灃謁麩溝賚淶鋸餓嶁諒綢風(fēng)轎。The findings, published in the journal Psychosomatic Medicine, build on evidence that a positive emotional style5 can help ward off6 the mon cold and other illnesses. Researchers believe the reasons may be both objective as in happiness boosting immune function and subjective as in happy people being less troubled by a scratchy throat or runny 。People with a positive emotional style may have different immune responses to the virus, explained lead study author Dr Sheldon Cohen of CarnegieMellonUniversity in Pittsburgh. And when they do get a cold, they may interpret their illness as being less severe. 兒躉讀閌軒鯀擬釔標(biāo)藪疇礎(chǔ)處櫚顫蹌。Cohen and his colleagues had found in a previous study that happier people seemed less susceptibleto8 catching a cold, but some questions remained as to9 whether the emotional trait itself had the effect. 繅藺詞嗇適籃異銅鑑驃噴麗頡趨顥冪。For the new study, the researchers had 193 healthy adults plete standard measures of personality traits, selfperceived health and emo
