A report released by NICE says. It says if they must drink, they should not do so in the first three months and should limit 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. Previous draft guidance suggested women should drink an ounce of alcohol a day once they were past the first three months of pregnancy.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 pregnancy can cause fetal alcohol syndrome (胎儿酒精综合症), which can leave children with features like small heads, widely spaced eyes and behavior or learning problems,‎ ‎ 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 (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 to the point of drunkenness on one occasion, the risk to her baby is small."‎ ‎ NICE also made a number of other recommendations for the care of women in the UK who were pregnant or planning to get pregnant. It said vitamin D and folic acid (叶酸) supplements should be offered by health staff to help avoid conditions such as rickets (软骨病) and spina bifida (脊椎裂). Officials also called for local health officials to ensure equal support plans where mothers encourage new parents to breastfeed are set up. NICE also called for improvements in the care of pregnant women with diabetes. About 20;000 pregnancies each year are affected by diabetes and, therefore, carry, higher risk of miscarriage (流产) and still birth. The guidance said women should get access to advice and ‎ support, in particular to achieve good blood sugar control before they get pregnant.‎ ‎41. What is the advice made by the Department of Health on drinking alcohol during pregnancy?‎ ‎ A. Little in the first three months and a gradual increase afterwards.‎ ‎ B. An ounce a day after the first three months. ‎ ‎ C. No drinking for pregnant women.‎ ‎ D. Those who drink regularly need not worry about the harm to their babies.‎ ‎42. What's the meaning of the underlined word "categorically'' in Paragraph 3 ?‎ ‎ A. Honestly. B. Absolutely. C. Physically. D. Doubtfully.‎ ‎43. According to the passage, miscarriage is caused most probably by __________.‎ ‎ A. the lack of vitamin D and folic acid ‎ B. rickets and spina bifida ‎ C. the lack of doctors' advice and support ‎ D. diabetes carded by pregnant women ‎44. National Childbirth Trust found that __________. ‎ ‎ A. a pregnant woman drinking alcohol infrequently has little risk to her baby ‎ B. pregnant women who drink a little occasionally are always afraid ‎ of the effects ‎ C. there is no evidence that a pregnant woman drinking alcohol might harm her baby ‎ D. getting drunk once won’t harm the baby ‎45. In this passage, the author mainly intends to ___________. ‎ ‎ A. show NICE's new guidance on pregnant women's alcohol drinking and its advice for the care of pregnant women ‎ B. warn pregnant women against any alcohol during pregnancy ‎ C. show the present situation of pregnant women's drinking limit ‎ D. call for more care for pregnant women in society ‎4基础写作 ‎ ‎ [写作内容]‎ ‎ 假如你的美国朋友John想了解有关2010年在广州召开的第16届亚运会的一些情况，现在让你给他写一封信介绍第16届广州亚运会会徽及意义，信件内容应包含以下内容：‎ ‎ 1．太阳，意味着亚运会充满活力；‎ ‎ 2．五羊标志，代表广州及其人民的美好愿望：‎ ‎ 3．四条跑道和五羊结合成燃烧的火炬，象征燃烧着的亚运会圣火：‎ ‎ 4．会徽里的文字表示第16届亚运会举办的地点和时间。‎ ‎ [写作要求] ‎ ‎ 1．只能使用5个句子表达全部的内容。‎ ‎ 2．信的开头已给出不算词数。‎ ‎ 3．文中不能出现真实姓名和学校名称。‎ ‎ [评分标准]‎ ‎ 句子结构准确，信息内容完整，篇章结构连贯。‎ ‎ [写作向导]‎ ‎ 1．时态：介绍第16届广州亚运会会徽及意义，应该用一般现在时为主要时态。‎ ‎ 2．可用词汇与句型：sacred flame圣火,the Emblem of the l6th Asian Games第16届广州亚 ‎ 运会会徽，the Five Goats五羊标志，Track跑道，dynamic，adj充满活力的．dynamism n，充满活力，combination n．结合。‎ Dear John,‎ ‎ How are you?

What's more, the English words in the emblem show that the 16th Asian Games will be hosted in Guangzhou in 2010.‎ ‎ Yours,‎ ‎ Li Hua
