Dangers Await Babies with Altitude
Women 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 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 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 life
B: underweight babies have a shorter life span
C: babies born to poor families lack certain hormones before birth
D: newborns in wealthy families have larger heads compared with their bodies

A young woman rode with her new husband in a wagon（四轮马车）.They came to a log cabin（小木屋）.The man shouted and a little boy came running out of the cabin.Sarah,the young woman,got down from the wagon,opened wide her arms and heldthe boy close.
"Hello,Abe Lincoln,"she said."I think we′ll be good friends."
The new mother with the smiling face went to work at once.She washed Abe and hissister and tidied（弄整齐）their hair.And that night she threw away the boy′s mattress（床垫）of leaves and gave him a soft mattress and enough blankets to keephim warm at night.
Sarah wove cloth and made new shirts for Abe.She made him new deerskin trousers and even deerskin shoes.
Maybe,if she hadn′t come to the cabin,he wouldn′t have lived to be a man.When Abe′s father told him not to go to school any more and help on the farm,Sarah took Abe′s part against his father.Abe would rather read than eat,and when hisfather told him to stop,Sarah said,"Let the boy read."
In 1830 the day came when Abe would leave home to work in New Salem.For the last time she had taken Abe′s part against his father.For the last time she had kept the cabin quiet so that Abe could read.More than twenty years later,when Abe,who had then become famous,was going to make a speech in a nearby town,Sarah went there just to watch him.In the crowd she tried to make herself small,but he saw her,and in front of everybody,got out of his carriage and went overand put his arms around her and kissed her.Yes,that was her Abe.
"Heloved me truly,"she said later.

Which of the following is not true?

A.The young woman in the wagon was Abe's new mother.
B.The man in the wagon was Abe's new father.
C.The little boy was the young woman's new son.
D.The little boy running out of the cabin was Abe.
