Pregnancy(妊娠) and childbirth kill more than 536,000 women a year. More than half of the cases happened in Africa, according to the World Health Organization. In fact, most of the deaths are preventable with basic medical care.
The five leading causes are bleeding, infection, high blood pressure, long­time labor and bad abortions (流產(chǎn)). Mothers' deaths from such causes were largely reduced nearly a century ago in developed countries.
Experts say that what kill many women are “the three delays”— the woman's delay in deciding to go to the hospital, the time she loses traveling there and the hospital's delay in starting treatment. Only about 15 percent of births have dangerous complications(并發(fā)癥).
Women lack education and information about birth control. Husbands and in­laws, may decide where a woman gives birth and insist that she stay at home to save money. However, there is no single solution to a problem with so many factors—shortages of doctors, nurses, drugs, equipment, roads and transportation—though hospital officials are trying many things now.
One stopgap measure to solve the problem for the present has been to train assistant medical officers, to perform certain operations. Some African countries are now struggling to train more assistants and midwives (接生婆) , and provide places for pregnant women to stay near hospitals.
But there is a long way to go. Only 20 percent of women in the continent give birth at the hospital. More than 50 percent stay at home to give birth, and the rest go to local clinics that cannot handle emergencies.
【小題1】Which is not included in the five leading causes of women's deaths during pregnancy and childbirth?

A.Infection.B.High blood pressure.
C.Traveling long distances.D.Bleeding.
【小題2】The underlined word “stopgap” probably means “________ ”in the passage.

A.The governments of African countries have to take more effective measures to save pregnant women.
B.Developed countries should help African countries reduce mothers'deaths.
C.The husbands in poor countries should take responsibility for their wives'deaths.
D.Most problems that cause women's deaths during pregnancy and childbirth can be treated or prevented.
【小題4】What is the author's attitude towards the future of preventing women's deaths during pregnancy and childbirth?
A.Positive.B.Negative.C.Objective.D.Subjective.

閱讀下列短文,從每題所給的A、B、C和D項(xiàng)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。
For most pregnant women, exercise is the last thing on their minds. After all, keeping slim while you’re expecting isn’t exactly the top priority— rather, it’s making sure your baby gets enough nutrients to grow. But in a small new study, researchers at the University of Auckland in New Zealand report that a mother’s regular aerobic exercise may be good for a growing fetus’ health — and may even help a baby get a healthier start in life.
The finding is a bit surprising, because exercise is known to lower the risk of insulin resistance(胰島素抵抗),a condition eventually leading to diabetes(糖尿。. Although insulin resistance is a detriment in healthy adults, it turns out to be helpful for proper fetal(胎兒)development. In pregnant women, this condition means nutrients get shunted to the growing baby.
The question is: could a mother’s exercise put her developing baby’s food supply at risk? Past studies looking at the effect of exercise on birth weight have been inconclusive, and none have really investigated the influence of exercise on the mother’s sensitivity to insulin. So the University of Auckland’s Dr. Paul Hoffman and his team decided to study 84 first-time mothers, who were of normal weight on average, and track any effects aerobic exercise(有氧運(yùn)動(dòng)) might have on their insulin sensitivity and, ultimately, on their babies’ birth weight. Researchers asked some women to exercise on a stationary bicycle for at least 40 minutes per session, up to five times each week, starting in the 20th week of pregnancy; the other women were not specifically asked to exercise. When the two groups and their babies were compared, the team found that women who bicycled regularly gave birth to babies who were on average 150g lighter than those born to the non-exercising mothers. In both groups, however, the babies were of healthy weight, and there was no difference in the mothers’ weights.
Generally speaking, babies on the lower end of the normal weight range are considered healthier and less prone to developing diabetes and obesity than heavier ones, so this was an encouraging result. Even more reassuring was that regular exercise did not seem to affect the flow of nutrients to the growing babies in the womb.
1. According to the new study, a pregnant woman’s regular exercise may _______.
A. bring benefits to a baby’s growth
B. lower the risk of insulin resistance
C. put her baby’s food supply at risk
D. help her keep slim and healthy
2. What does the underlined word “detriment” mean in the second paragraph?
A. Something that brings good.
B. Something that brings damage.
C. Something that brings obstacles.
D. Something that brings development.
3. What is the purpose of the experiment carried out by Dr. Paul Hoffman?
A. To investigate the influence of exercise on pregnant women.
B. To find out what aerobic exercise can benefit a baby’s growth.
C. To make sure of the effects exercise may have on babies’ birth weight
D. To compare the differences between mothers who exercise and who don’t
4. Which of the following statements is true according to the passage?
A. Lighter babies are generally believed to be healthier than heavier ones.
B. Non­-exercising mothers will definitely give birth to heavier babies.
C. No studies have looked at the effect of exercise on birth weight before.
D. Some women studied were asked to exercise regularly while some don’t.
5. Which of the following may be the best title for the passage?
A. All mothers should take aerobic exercise.
B. Moms who exercise give birth to lighter babies。
C. Exercise reduces the risk of insulin resistance.
D. Heavier babies are more likely to develop diabetes.

While I was in my 4th month of pregnancy (妊娠期) with my second child, we were preparing for a trip to Louisiana, where Marshall’s family live, to celebrate Jane’s 2nd birthday. Two days before we were to leave, we got the shocking news that I was going to lose the baby. Not knowing when this would happen, we decided to continue with our trip.

Since Marshall’s family lives on a 600-acre cattle farm, you often find that you have a lot of time to yourself to think when you are there. That is precisely what I did not want to do at this time. I told Marshall that I needed to get a good book to get lost in while I was there. I told him I heard the Harry Potter books were good, so he went out and got the first one for me.

During that trip, I totally got lost in the book, which was of great help during a time when I needed a distraction to forget about the sadness. In the book, I noticed the name “Seamus”. I vaguely remembered it was pronounced “Shamus” and I liked the sound of that. I mentioned it to Marshall and he liked it too. Toward the end of the trip, I had just 5 chapters left and I knew I was about to finish the first book, which I was pretty excited about.

Soon after we put Jane down to bed, I had started labor (分娩), so I was unable to read. The labor lasted 5 and 1/2 hours, but Marshall stayed there with me, sitting beside me and reading aloud the last 5 chapters of Harry Potter. I can never fully explain how much that helped me through the experience. And ever since then, Marshall and I both have been fans of the Harry Potter books. We remember how they helped us get through that time of our lives.

We were sad to have lost the baby, but the name Seamus started our journey toward adoption. And we gave this name to our adopted son. Though our Seamus doesn’t have a drop of Irish blood in him, the name fits him perfectly.

1.Why did the writer want a good book during the trip?

A. Because the trip to Louisiana would take a long time.

B. Because she didn’t want to think of losing her baby.

C. Because she had nothing else to do except reading.

D. Because a good book could help her enjoy her trip.

2.According to the story, we can know that the Harry Potter books _________________.

A. made the family’s trip more exciting

B. include five books all together

C. have someone called Seamus in them

D. can help people deal with their problems

3.The writer named her son Seamus because ___________________.

A. she wanted to keep her trip in memory

B. she loved this name very much

C. her son doesn’t have Irish blood

D. it is a perfect name for a boy

4.Which of the following is TRUE about the couple?

A. They planned their trip after getting the shocking news.

B. They thought the cattle farm was too large to do anything on.

C. They felt excited when they almost finished the trip.

D. They liked reading Harry Porter very much after the trip.

5.Which is the best title for the passage?

A. Funny Stories Of My Family           B. Seamus And Harry Potter

C. How We Got To Louisiana              D. How My Son Got His Name

Using a Mobile Phone to Improve Mother and Child Health

People around the world are working to expand the uses for mobile technology in health care.

In the world, there are six billion mobile phone users in a population of seven billion people.

   1.     Africa has widespread adoption. Three or four years ago the penetration rates were 20 percent or 30 percent, and now they’re getting upwards of 60 percent in some countries.

    2.     Earlier research has been to look at mobile technologies and HIV and AIDS. And so we have some great evidence on the effectiveness of mobiles.

During the first week of December, 2012, more than 4,000 people from 50 countries met for the fourth annual mHealth Summit. It brought together experts from what the organizers call the mHealth ecosystem.

In 2011 Secretary of State Hillary Clinton started a public/private partnership called the Mobile Alliance for Maternal Action, or MAMA. There are about 800 women a day and about three million babies a year die from pregnancy and childbirth-related causes.      3.     The messages cover pregnancy and the first year of a baby’s life. These health messages may also be sent to a pregnant woman’s husband and mother-in-law.    4.    

Messages can be text or voicemail. You can have a pregnant woman in Bangladesh registered into a system that provides messages that help her know what to do and when to do certain things.

Simple text messages can be important sources of information to people without Internet

access.      5.     They have to be able to read through thousands of entries that come back to them on Google, for example, and then figure out what that information means to them. And that’s not something that someone in a poor and uneducated kind of situation can do.  

A.They have no access to the relevant information.

B.That way they too can understand what needs to be done.

C.Millions of messages about baby care are received every day.

D.A lot of work has been done to use mobile technology for health.

E. And the most rapidly growing markets are those in developing countries.

F. The program sends messages to women to educate them about their health.

G. Besides, online users may sometimes not understand all the information available.

When I first saw the book Alice in Lace, I thought I was going to like it. And as it turned out, I love it! I love books about life and being a kid. And Alice in Lace is just that kind. It’s a humorous book about being thirteen and the problems kids might face. Alice and her friends get a strange assignment from their totally cool teacher, Mr. Everett. It was like playing the game of “Life,” but you had to act it out.

So Pamela is pregnant, Elizabeth buys a car and Alice gets married. Well, of course, Pamela wasn’t really pregnant, but she walked around with a pillow under her shirt to get people’s reactions. Elizabeth didn’t really buy a car, but she went to the car lot and made the sales guy think she was. The whole class got assignments like these! I would love to do something like that for school.

In the book Alice has a lot to think about. “Getting married is hard!” Alice says. She has to plan the ceremony, the honeymoon, find a place to live, pay for furniture and two months’ rent and food. Maybe she and her “husband” could work it out — if they were getting on fine!

Although this book was funny, it really made me think about how problems like these could really mess up your life. Take teenage pregnancy for example. How could you have a baby and stay in school? You couldn’t find a babysitter every day to stay with your kid. A child really consumes your life. I understand what the teacher was trying to do. He was trying to discourage the class from getting into these problems by giving them a glimpse of life. As someone about to become a teenager myself, I can say sometimes a story makes you think about what’s up ahead.

Overall, I would say this book is wonderful. My favorite part of the book is discovering that if I like it, there are seven other Alice books I can check out at my local library. I love this book, and I hope you will too.

1.We can infer from the passage that Pamela, Elizabeth and Alice _______.

A.turn out to be the author’s classmates

B.a(chǎn)re characters in Alice in Lace

C.get along quite well

D.become dismissed from school

2.By saying “getting married is hard” in the paragraph 3, Alice means ______.

A.life isn’t easy as expected

B.it is hard to deal with her husband

C.she regrets getting married

D.it’s fun to get married

3.Why did Mr. Everett give his students such assignments?

A.To encourage them to enjoy a meaningful life.

B.To prevent them getting into those troubles at an early age.

C.To make them realize the hardship of life.

D.To teach them how to make a living.

4.The author writes the passage mainly to _____.

A.a(chǎn)dvise us to buy Alice in Lace

B.tell us how wonderful Mr. Everett’s idea is

C.share her inspiration from Alice in Lace

D.show off her reading ability
