A report released by NICE says if they must drink, they should not do
8、so in the first three months and should limit consumption to one or two ounces once or twice a week afterwards. It replaces previous guidance of saying small daily amounts were fine.NICE decided to tighten its guidance partly because of the concern that people are now drinking more than in the past.
9、 Previous draft guidance suggested women should drink an ounce of alcohol a day once they were past the first three months of pregnancy. The Department of Health in England changed its guidance last year, calling for no drinking while pregnant or while trying to get pregnant. Drinking heavily in pre

11、 out(排除)any risk. National Childbirth Trust agreed women should limit their drinking during pregnancy. “Pregnant women who have had a few drinks often worry a great deal about whether they have harmed their baby. In general, it is believed that if a light infrequent drinker, in good health, drinks t

NICE also called for improvements in the care of pregnant women with diabetes(糖尿病). About 20，000 pregnancies each

28、建议孕期女士不要饮酒。文中涉及了英国不同健康机构以及英国政府对孕妇饮酒事宜的不同规定，但是同时指出了孕妇饮酒会对胎儿有不良的影响，从而呼吁孕妇限制饮酒甚至不要饮酒。同时，NICE还对怀孕和准备怀孕的女士保健工作提出了一些其他的建议，提倡社会各界来关注孕妇的健康。16C细节理解题。题干考查the Department of Health关于孕妇喝酒的建议，由文中第二段的The Department of Health in England changed its guidance last year, calling for no drinking while pregnant or while
29、 trying to get pregnant.可以看出，该机构现在呼吁孕妇不要喝酒，因此C项正确。17B词义猜测题。根据词汇所在的句子The experts said there was no evidence that several ounces once or twice a week would do any harm to the baby but could not categorically rule out any risk.的句意：专家认为没有证据表明一周内喝一次或两次几盎司的酒就会对胎儿造成伤害，但是不能categorically排除任何危险。根据下段的最后一句中的the
30、 risk to her baby is small可知少量饮酒对胎儿会造成比较微小的伤害，所以categorically在这里意为“完全地”。18D细节理解题。根据文章最后一段的About 20，000 pregnancies each year are affected by diabetes and, therefore, carry higher risk of miscarriage and stillbirth.可以看出，患有糖尿病的孕妇有着很高的流产风险，所以应该选D。19B细节理解题。第五段是National Childbirth Trust的发现Pregnant women
31、who have had a few drinks often worry a great deal about whether they have harmed their baby.可以看出，即使喝酒不多的孕妇也会很担心喝酒会对胎儿不利，所以B正确。A项是不完整的，文中说In general, it is believed that if a light infrequent drinker, in good health, drinks to the point of drunkenness on one occasion, the risk to her baby is small.可
32、知对胎儿造成比较微小的危险的怀孕妇女有以下特征：light, infrequent drinker, in good health, on one occasion，而A选项只是断章取义，所以错误；同理D项也由此判断为错误选项。20A作者意图题。作者刚开始介绍了NICE关于孕妇饮酒的新规定，然后最后一段NICE提出了一些关爱英国怀孕妇女的建议，所以应该选A。B文章向我们介绍了传奇科学家霍金。21A细节理解题。由第三段的But my classmates gave me the nickname Einstein，so presumably they saw signs of something
33、 better.可知绰号“爱因斯坦”是同学给起的，但并不意味着他就是第二个爱因斯坦。故A项不符合文意。22B推理判断题。由第一段特别是But outstanding astrophysicist Stephen Hawking has admitted that he did not learn to read until he was eight years old.和第二段开头句可知，他小时候和在大学里是非常懒惰的。故选B项。23C细节理解题。由第二段最后一句only the diagnosis that he might die young from motor neurone dise
34、ase made him concentrate on his work.可知，是“运动神经元疾病”促使他有所作为。故选C项。24B段落大意题。由最后一段，特别是信息句He said，“When you are faced with the possibility of an early death，it makes you realize that life is worth living and there are lots of things you want to do.”可知，他有可能要面对英年早逝的不幸事实。故选B项。25B细节理解题。根据第三段最后霍金的话可知，尽管老师不看好他，同学仍给他“爱因斯坦”的绰号，他们从他身上看到好的一面。6
