Safe Coffee Drinking of Pregnant Women

1 researchers found no evidence of a link between prematurity ,birth weight and the amount of caffeine consumed by mothers-to-be.

2 previous studied suggested caffeine might harm unborn babies as is stays in the system longer in pregnant women, passing easily to a growing baby. Health officials have warned that a high caffeine intake could affect birth weight or the chance of having a miscarriage , pregnant women are advised against drinking more than four cups of coffee a day-or six cups of tea.

3 the study ,by the university of Aarhus in Denmark ,recruited more than 1,000women before they were 20 week’s pregnant, who drank at least three cups of coffee a day. The group was split into two, with 568 women drinking ordinary instant coffee and 629 drinking decaffeinated. The authors then monitored the birth weight of 1,150 newborn babies and the length of pregnancy for the babies.

4 the study, published by the British Medical Journal, found “no significant difference” between the two groups for birth weight or length of pregnancy. The researchers concluded that a moderate reduction in caffeine intake in the second half of pregnancy had “no effect” on the outcome.

5 the women were not told what type of coffee they were drinking ,and the research was adjusted to take into account factors such as age, weight and whether the women smoked. When the adjustments were made, the average weight of babies born to women in the decaffeinated group was a mere 16g higher than those born to women in the caffeinated group, the study said. The average difference in the length of pregnancy was less than two days.

6 A spokeman for the British Coffee Association said:”this new study is very interesting and supports the consistent advice given that pregnant women should stick to a safe upper limit- in line with guidance issued by the Food Standards Agency. This equates to three cups of brewed, or four cups of instant coffee.”

參考答案：D B C E D A B E

答案解析：

23 D 第二段提到了以前的關(guān)于孕婦攝入咖啡因的調(diào)查結(jié)果和一些鑒于該研究基礎(chǔ)上對于孕婦的忠告。

24 B 第三段主要講的是對于孕婦的分組試驗以檢測咖啡因?qū)τ谠袐D的影響。

25 C 第五段在實驗的結(jié)果上總結(jié)適當(dāng)攝入咖啡因和未咖啡因?qū)τ谔旱暮腿殉狡诘挠绊懯俏⒑跗湮⒌摹?/p>

26 E 第六段主要是通過試驗得出的結(jié)論，即適當(dāng)攝入咖啡因是安全的，并提出了安全飲用咖啡的數(shù)量。

27 D 問題問的是：一些衛(wèi)生官員對咖啡因高攝取量持什么樣的觀點？第二段的health officials have warned that a high caffeine intake could affect birth weight or the chance of having a miscarriage,指出咖啡因高攝取量會影響胎兒的體重并且增大流產(chǎn)的幾率。注意miscarriage和abortion的同義轉(zhuǎn)換。

28 A 問題問的是：衛(wèi)生官員們對孕婦有什么樣的建議？根據(jù)第二段pregnant women are advised against drinking more than four cups of coffee a day-or six cups of tea.得出孕婦應(yīng)當(dāng)適量飲用咖啡與茶。

29 B 問題問的是：Aarhus 大學(xué)的試驗怎么樣？文章的第五段提到未射入咖啡因的那組孕婦所生嬰兒的平均體重僅為16克。而兩組孕婦妊娠期長度的平均差別還不到兩天。所以得出兩組孕婦的妊娠期沒有很大的區(qū)別。

30 E 問題問的是：新的試驗結(jié)果表明了孕婦應(yīng)該怎么辦？最后一句提到了孕婦每天可以喝三杯煮咖啡，或四杯速溶咖啡。因此E是正確的選項。
