1.Some of the most commonly used medicines for high blood pressure are drugs called ACE inhibitors（抑制剂）.Doctors have given these drugs to patients for twenty-five years.A government study in the United States found that the use almost doubled between 1 995 and 2000.2.Doctors have known for years that women should not take ACE inhibitors during the last six months of pregnancy（怀孕）.The medicine can injure the bahy.ACE inhibitors,though,have been considered safe when taken during the first three months.But a new study has found that women who take these drugs early in their pregnancy still increase the risk of hirth disorders（先天性疾病）.Thestudyshowsthat,comparedtoothers,theirbabieswerealmostthreetimesaslikely to be horn with major problems.These included problems with thefo朋ation of the brain and nervous system and holes in the heart.3.The researchers say they found no increased risk in women who took other blood pressure medicines during the first three months.Researchers at Vanderbilt University in Tennessee and Boston University did the study. The New England Journal of Medicine published the results.The researchers studied the records of almost thirty thousand births between 1985 and 2000.Two hundred nine babies were born to women who took ACE inhibitors during the first three months of their pregnancies.Eighteen of the babies,or almost nine percent,had major disorders.4.ACE inhibitors are often given to patients with diabetes（糖尿病）.But diabetes during pregnancy can result in birth defects（先天性缺陷）.So the study did not include any women known to be diabetic. ACE inhibitors suppress a protein called angiotensin-converting enzyme（血管紧张素转化酶）,or ACE. This enzyme produces a chemical in the body that makes blood passages narrow. The drugs increase the flow of blood,so pressure is reduced.5.New drugs are tested on pregnant animals to see if they might cause birth defects in humans. But experts say these tests are not always dependable.The United States Food and Drug Administration helped pay for the study.The FDA says women who might become pregnant should talk with their doctor about other ways to treat high blood pressure.FDA suggests that pregnant women with high blood pressure should consult_________.A:that may cause our blood vessels to become more and more narrowB:for pregnant women to take during their last six months of pregnanciesC:that their likelihood to suffer major problems is two times higher than other babiesD:with their doctors about how to treat their problemsE:because diabetes during pregnancy may sometimes lead to birth defectsF: though their mothers took ACE inhibitors during their first three months of pregnancies

Dangers Await Babies With AltitudeWomen who live in the world's highest communities tend to give birth to underweight babies,a new study suggests.These babies may grow into adults with a high risk of heart disease and strokes.Research has hinted that newborns in mountain communities are lighter than average.But it wasn't clear whether this is due to reduced oxygen levels at high altitude or because their mothers are under-nourished一many people who live at high altitudes are relatively poor compared with those living lower down.To find out more,Dino Giussani and his team at Cambridge University studied the records of 400 births in Bolivia during 1997 and 1998.The babies were born in both rich and poor areas of two cities:La Paz and Santa Cruz.La Paz is the highest city in the world,at 3.65 kilometers above sea level,while Santa Cruz is much lower,at 0.44 kilometers.Sure enough,Giussani found that the average birthweight of babies in La Paz was significantly lower than in Santa Cruz.This was true in both high and low-income families.Even babies born to poor families in Santa Cruz were heavier on average than babies born to wealthy families in lofty La Paz."We were very surprised by this result,"says Giussani.The results suggest that babies born at high altitude are deprived of oxygen before birth."This may trigger the release or suppression of hormones that regulate growth of the unborn child," says Giussani.His team also found that high-altitude babies tended to have relatively larger heads compared with their bodies.This is probably because a fetus starved of oxygen will send oxygenated blood to the brain in preference to the rest of the body.Giussani wants to find out if such babies have a higher risk of disease in later life. People born in La Paz might be prone to heart trouble in adulthood,for example.Low birth weight is a risk factor for coronary heart disease.And newborns with a high ratio of head size to body weight are often predisposed to high blood pressure and strokes in later life.Giussani's team members are all British researchers and professors from Cambridge University.A:RightB:WrongC:Not mentioned

Passage?One
The small number of newborn babies,which has been caused by high prices and the changing social situation of women,is one of the most serious problems inAsia.When people talk about it,you can hear a word invented inJapan,"DINKS",which means Double Income No Kids.
In many majorAsian cities like Seoul,Singapore,and Tokyo,the cost of a house is extremelyhigh.A young couple who want to buy their own house may have to pay about$300,000（though prices have fallen）.For a flat with one bedroom,onedining-room,a kitchen,and a bathroom,the couple will pay about$900 amonth.What′s more,if they want to have a child,the child′s education is veryexpensive.For example,most kindergarten charges are at least$5,000 a year.In such a situation,it′s difficult to afford children.
The number ofmarried women who want to continue working increases rapidly because they enjoytheir jobs.However,if they want to have children,they immediately haveserious problems.Though most companies allow women to leave their jobs for ashort time to have a baby,they expect women with babies to give up their jobs.In short,if they want to bring up children properly,both parents have towork,but it is hard for mothers to work.Indeed,women who want to continueworking have to choose between having children or keeping their jobs.
In a word,Asiangovernments must take steps to improve the present situation as soon aspossible.
What is the main problem beingdiscussed in the passage?A.The small number of newborn babies.
B.The changing social situation of women.
C.The high prices of houses andeducation.
D.The necessary steps of Asiangovernments.

Pregnant Women Warned About ACE InhibitorSome of the most commonly used medicines for high blood pressure are drugs called ACE in-hibitors.Doctors have given these drugs to patients for twenty-five years.A government study in the United States found that the use almost doubled between 1995 and 2000.Doctors have known for years that women should not take ACE inhibitors during the last six months of pregnancy.The medicine can injure the baby.ACE inhibitors,though,have been con-sidered safe when taken during the first three months. But a new study has found that women who take these drugs early in their pregnancy still increase the risk of birth disorders. The study shows that,compared to others,their babies were almost three times as likely to be born with major problems .These included problems with the formation of the brain and nervous system and holes in the heart.The researchers say they found no increased risk in women who took other blood pressure medicines during the first three months.Researchers at Vanderbilt University in Tennessee and Boston University did the study.The New England Journal of Medicine published the results. The researchers studied the records of almost thirty thousand births between 1985 and 2000.Two hun-dred nine babies were born to women who took ACE inhibitors during the first three months of their pregnancies.Eighteen of the babies,or almost nine percent,had major disorders.ACE inhibitors are often given to patients with diabetes. But diabetes during pregnancy can result in birth defects.So the study did not include any women known to be diabetic.ACE inhibi- tors suppress a protein called angiotensin-converting enzyme or ACE.This enzyme produces a chemical in the body that makes blood passages narrow.The drugs increase the flow of blood so pressure is reduced.New drugs are tested on pregnant animals to see if they might cause birth defects in humans. But experts say these tests are not always dependable.The United States Food and Drug Adminis- tration helped pay for the study .The F. D.A.says women who might become pregnant should talk with their doctor about other ways to treat high blood pressure. Evidence showed only a small percentage of babies suffered major disorders______.A: that may cause our blood vessels to become more and more narrowB: for pregnant women to take during their last six months of pregnanciesC: that their likelihood to suffer major problems is two times higher than other babiesD: with their doctors about how to treat their problemsE: because diabetes during pregnancy may sometimes lead to birth defectsF: though their mothers took ACE inhibitors during their first three months of pregnancies

Dangers Await Babies with AltitudeWomen who live in the world's highest communities tend to give birth to underweight babies, a new study suggests.These babies may grow into adults with a high risk of heart disease and strokes.Research has hinted that newborns in mountain communities are lighter than average.But it wasn't clear whether this is due to reduced oxygen levels at high altitude or because their mothers are under-nourished—many people who live at high altitudes are relatively poor compared witf those living lower down.To find out more,Dino Giussani and his team at Cambridge University studied the records of 400 births in Bolivia during 1997 and 1998.The babies were born in both rich and poor areas of two cities:La Paz and Santa Cruz.La Paz is the highest city in the world,at 3 .65 kilometers above sea level,while Santa Cruz is much lower,at 0 .44 kilometers.Sure enough,Giussani found that the average birthweight of babies in La Paz was significantly lower than in Santa Cruz.This was true in both high and low-income families.Even babies borr to poor families in Santa Cruz were heavier on average than babies born to wealthy families in lofty La Paz.“We were very surprised by this result,”says Giussani.The results suggest that babies born at high altitude are deprived of oxygen before birth. “This may trigger the release or suppression of hormones that regulate growth of the unborn child,”says Giussani.His team also found that high-altitude babies tended to have relatively larger heads compared with their bodies.This is probably because a fetus starved of oxygen will send oxygenated blood to the brain in preference to the rest of the body.Giussani wants to find out if such babies have a higher risk of disease in later life.People born in La Paz might be prone to heart trouble in adulthood,for example.Low birthweight is a risk factor for coronary heart disease .And newborns with a high ratio of head size to body weight are often predisposed to high blood pressure and strokes in later life. It can be learned from the last paragraph that＿________.A: high-altitude babies tend to have high blood pressure in their later lifeB: underweight babies have a shorter life spanC: babies born to poor families lack certain hormones before birthD: newborns in wealthy families have larger heads compared with their bodies

Pregnant Women Warned About ACE InhibitorSome of the most commonly used medicines for high blood pressure are drugs called ACE in-hibitors.Doctors have given these drugs to patients for twenty-five years.A government study in the United States found that the use almost doubled between 1995 and 2000.Doctors have known for years that women should not take ACE inhibitors during the last six months of pregnancy.The medicine can injure the baby.ACE inhibitors,though,have been con-sidered safe when taken during the first three months. But a new study has found that women who take these drugs early in their pregnancy still increase the risk of birth disorders. The study shows that,compared to others,their babies were almost three times as likely to be born with major problems .These included problems with the formation of the brain and nervous system and holes in the heart.The researchers say they found no increased risk in women who took other blood pressure medicines during the first three months.Researchers at Vanderbilt University in Tennessee and Boston University did the study.The New England Journal of Medicine published the results. The researchers studied the records of almost thirty thousand births between 1985 and 2000.Two hun-dred nine babies were born to women who took ACE inhibitors during the first three months of their pregnancies.Eighteen of the babies,or almost nine percent,had major disorders.ACE inhibitors are often given to patients with diabetes. But diabetes during pregnancy can result in birth defects.So the study did not include any women known to be diabetic.ACE inhibi- tors suppress a protein called angiotensin-converting enzyme or ACE.This enzyme produces a chemical in the body that makes blood passages narrow.The drugs increase the flow of blood so pressure is reduced.New drugs are tested on pregnant animals to see if they might cause birth defects in humans. But experts say these tests are not always dependable.The United States Food and Drug Adminis- tration helped pay for the study .The F. D.A.says women who might become pregnant should talk with their doctor about other ways to treat high blood pressure. ACE is a risk factor to our body______.A: that may cause our blood vessels to become more and more narrowB: for pregnant women to take during their last six months of pregnanciesC: that their likelihood to suffer major problems is two times higher than other babiesD: with their doctors about how to treat their problemsE: because diabetes during pregnancy may sometimes lead to birth defectsF: though their mothers took ACE inhibitors during their first three months of pregnancies
