A brain-dead woman who was kept alive for three months so she could deliver the child she was carrying was removed from life support on Wednesday and died, a day after giving birth.
"This is obviously a bittersweet time for our family," Justin Torres, the woman#39;s brother-in-law, said in a statement.
Susan Torres， a cancer-stricken， 26-year-old researcher at the National Institutes of Health， suffered a stroke in May after the melanoma （黑瘤） spread to her brain.
Her family decided to keep her alive to give her foetus （胎儿） a chance. It became a race between the foetus#39; development and the cancer that was destroying the woman#39;s body.
Doctors said that Torres#39; health was getting worse and that the risk of harm to the foetus finally outweighed the benefits of extending the pregnancy.
Torres gave birth to a daughter by Caesarean section （剖腹产手术） on Tuesday at Virginia Hospital Center. The baby was two months premature and weighed about a kilogram. She was in the newborn intensive care unit.
Dr Donna Tilden-Archer， the hospital#39;s director of neonatology （新生儿学）， described the child as "very vigorous." She said the baby had responded when she received stimulation， indicating she was healthy.
Doctors removed Torres from life support early Wednesday with the consent of her husband， Jason Tortes， after she received the final sacrament （圣礼） of the Roman
Catholic Church.
"We thank all of those who prayed and provided support for Susan, the baby and our family," Jason Torres said in a statement. "We especially thank God for giving us little Susan. My wife#39;s courage will never be forgotten."
English-language medical literature contains at least 11 cases since 1979 of
irreversibly brain-damaged women whose lives were prolonged for the benefit of the
developing foetus, according to the University of Connecticut Health Center.
Dr Christopher McManus, who coordinated care 1"or Susan Torres, put the infant#39;s chances of developing cancer at less than 25 per cent. He said 19 women who have had the same aggressive form of melanoma as Tortes have given birth, and five of their babies became ill with the disease.
36 Susan Torres died soon after
A she suffered a stroke.
B she became brain-dead.
C she was diagnosed with cancer.
D she gave birth to a baby.
37 The pregnancy was stopped because
A the foetus was found seriously ill.
B the risks outweighed the benefits.
C there was no hope to rescue the foetus.
O the Tortes family couldn#39;t afford the expenses any more.
38 Which is NOT true of the baby?
A She was born of a dead mother.
B She was two months premature
C She weighed about a kilogram.
D She was healthy.
39 Susan Torres had been put on life support so
A she could live comfortably.
B she could see her baby.
C she could die without pain.
D she could deliver her baby.
40 The baby#39;s chances of developing cancer were said to be
A about 11 per cent
B around 19 per cent.
C less than 25 per cent.
D close to 5 per cent.
第三篇 Smart Exercise
Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and Science University, studies brain development. According to her research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developed. Dr. Cameron claims this allows people who exercise to concentrate better. As she says: "While we already know that exercise is good for the heart, exercise can literally cause physical changes in the brain."
The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. With babies， even a little movement can show big results. Margaret Barnes， a pediatrician （儿科医师）， believes in the importance of exercise. She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses. They need to establish a connection between motion and memory. In this way， as they get older， children will begin to associate physical activity with higher learning，" says Margaret.
Older people can beef up their brains as well. Cornell University studied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for infants, exercise for older people should involve some complexity. Learning some new skills or motions helps to open up memory paths in the brain that may not have been used for a long time.
For most people, any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain#39;s flow of blood. And your brain can benefit from as little as two to three hours of exercise a week.
41 Research by Dr. Cameron seems to suggest that exercise can
A generate new blood vessels.
B change the way a person thinks.
C promote brain development.
D divert one#39;s attention.
42 Margaret Barnes thinks that a lack of movement in infancy can
A lead to learning troubles later.
B cause physical disabilities later.
C stimulate the five senses.
D bring about changes in the brain.
43 The expression "beef up" in paragraph 3 means
A "control".
B "strengthen".
C "operate".
D "encourage".
44 To be beneficial, exercise for older people should
A be done in a group.
B be done on a daily basis.
C involve great difficulty.
D increase the heart rate.
45 The title of the passage implies that
A only smart people do exercise.
B exercise can be smart or stupid.
C exercise keeps the brain strong.
D it is fashionable to do exercise.
