Children who are brought up by two parents grow up to be cleverer than those raised by just one person, new research suggests. Being with both parents in the earliest years of life leads to a child developing more brain cells, the scientists believe. Being brought up by both parents causes boys to have better memory and learning functions. By contrast, it causes girls to develop improved co-ordination and sociability.
It is believed that babies with two parents tend to get more attention and more stability(稳定), and that they are less likely to suffer emotional distress(悲伤) in the first years of life. This leads to greater brain cell production ------ for boys it is grey matter brain cells that develop and for girls is white matter brain cells.
The researchers from Canada studied mice and experimented by creating one-parent and two-parent family groups. They then measured the offspring’s(后代的) brain cell development from birth to adulthood. Adult mice with the highest number of brain cells turned out to be those who had been brought up by two parents rather than one. As babies they had received more attention and more nursing as both parents took turns to lick and tend to their youngsters, said Dr Samuel Weiss.
As a result, the babies with two parents are less likely to suffer early life hurt which can have a massive impact on how their brains develop in later life, the research shows. However, what did surprise the researchers is that female babies who grew up with both parents turned out to be good single mothers, as if good parenting was passed on.
The researchers said,“ In the mouse model, parenting and the environment directly impacted adult brain cell production. It is possible that similar effects could be seen in other mammals, such as humans.”
1.From the first paragraph we can draw a conclusion that ________.
A. Girls have better memory and learning functions.
B. Boys are better at co-ordination and sociability.
C. The benefits vary between the sexes.
D. The benefits are the same between the sexes.
2.The researchers proved their idea ________.
A. by questionnaire on parents.
B. by experiment on mice.
C. by raising babies themselves.
D. by experiment on humans.
3.The underlined word “impacted” means _________.
A. destroyed B. constructed
C. influenced D. disagreed
4.What does the passage mainly tell us?
A. Children brought up by two parents are cleverer.
B. Children brought up by single parent are cleverer.
C. Children grow up themselves are cleverer.
D. Children grow up themselves are more self-confident.

“When I grow up, I want to be a runner.” These words are spoken by thousands of Kenyan children. 50 percent of the Kenyan top runners are members of Kalenjin, one minority race of the country. They make up less than two percent of Kenya’s population. This fact has puzzled sports scientists. They have spent considerable time and effort trying to answer one question: What enables the Kalenjin people to run so fast?
Although the question seems simple, finding the answer has proven to be difficult and controversial. A team of Danish sports scientists spent 18 months and discovered the Kalenjins had remarkably slow heart rates even when running long distances. The Kalenjins live in high-elevation（高海拔） villages in the Rift Valley in western Kenya. People living at high elevations produce more red blood cells, which aid in the transport of oxygen throughout the body. Because the air is thinner and contains less oxygen at high elevations, the body produces more red blood cells. Scientists believe there is a connection between increased red blood cells and low heart rates and that both may enable high-altitude athletes to outperform those who train at low altitudes. The Danish scientists also studied the bodies of the Kalenjins and compared them to those of the Danes. They found that the Kalenjins have longer “birdlike” legs. The Kalenjins also have lower body mass indexes (a measure of body fat based on weight and height) and shorter bodies than Danish people.
As a result of the Danish study, some scientists made the conclusion that the Kalenjins possess what is called a “speed gene(基因)”. However, Kenyan runners were offended by this conclusion They credited their success to hard work and endless hours of training.
Although the controversy over the “speed gene” remains unsolved, British runner Mo Farah’s experience offers an interesting perspective on the subject. In 2005, he realized he wasn’t meeting his potential as a runner. A group of Kenyan runners were training in England then. After he accidentally observed the Kenyans’ strict training routines and dedication to their sport, Farah said it was like a switch had been turned on in his head. He began eating healthy foods, going to bed early, and training harder than he had ever trained in his life. As a result, Farah’s running career exploded. He has won seven world and Olympic titles in the 5000m and regularly beats Kenya’s top runners!
Farah’s story proves what Kenyans have known all along. Regardless of genetics, their success would not be possible without hard work, dedication, sacrifice, and mental toughness. Their “secret” is simple. Train hard, run fast, and never give up.
1.What interested the sports scientists?
A.Kenyan sports history.
B.Kanlenjins’ running ability.
C.Kanlenjins’ training methods.
D.Kenyans’ enthusiasm for sport.
2.According to Danish scientists, what leads to the Kanlenjins’ success?
A.Physical condition. B.Hard training.
C.Living style. D.Strong will.
3.How did Kenyan runners think about Danish research result?
A.Convincing. B.Astonishing.
C.Unacceptable. D.Important.
4.Why is Mo Farah’s story mentioned in the passage?
A.To show running methods count.
B.To encourage British athletes.
C.To prove effort pays off.
D.To support gene theory.

高二英语单项填空简单题查看答案及解析
There are two great trends on parents bringing up children today．First，children are now praised to an unbelievable degree．As Dorothy Parker once joked，American children aren’t raised；they are motivated．Children are constantly told how special they are．The second is that children are honed(磨砺) to an unimaginable degree．Parents spend much more time than in past generations on their children’s development．
These two great trends—greater praise and greater honing—combine in close ways. Parents shower their kids with affection，but it is intermingled with the desire to help their children achieve success．Parents are happy when their child studies hard，practices hard，wins first place，gets into a famous college．
The wolf of conditional love is hidden in these homes．The parents feel they love their children in all circumstances．But the children often think differently．They feel that childhood is a performance—on the athletic field，in school and beyond．The shadowy presence of conditional love produces a fear，the fear that there is no completely safe love．
Meanwhile，children who are uncertain of their parents’ love develop a great hunger for it. This conditional love is1ike an acid that affects children’s criteria to make their own decisions about their own colleges，majors and careers．At key decision-points，they unconsciously imagine how their parents will react．
These children tell their parents those things that will bring praise and hide the parts of their lives that won’t. Studies suggest that children who receive conditional love often do better in the short run．They can be model students．But they suffer in the long run. They come to hate their parents．They are so influenced by fear that they become afraid of risk．
Parents today are less likely to demand obedience(顺从) with explicit rules and lectures．But they are more likely to use love as a tool to exercise control. But parental love is supposed to ignore achievement. It’s meant to be an unconditional support -a gift that can not be bought and cannot be earned．
1.What does the underlined word “intermingled” in Paragraph 2 mean?
A. Greeted． B. Mixed． C. Compared． D. Separated．
2.Some children can’t make their own decisions probably because________.
A. they have too many options B. they are lacking in parents’ advice
C. they are doubtful about parents’ love D. they care too much about parents’ reaction
3.What’s the author’s opinion about parental love？
A. It doesn’t go to children with poor grades.
B. It is meant to control children’s behaviour.
C. It shouldn’t focus on children’s achievement.
D. It works with strict rules and constant reminding.

Dear daughters,
Most parents tell their children, “You can be anything you want when you grow up.” I feel the same and I say this often. But I also want you to understand that realizing your dreams comes from hard work, some good luck and good timing.
Here are some words of wisdom for you as you make your way in the world, from an entrepreneur (企业家) and from your mama.
1. Be open-minded to changing your path along the way
In high school, I wanted to be a politician. I left my hometown and went off to college in Washington,
DC. There, I discovered that I loved to support women. It taught me that I’m creative, a strong leader and great at marketing. As a result, I moved on to be the head of a national healthcare nonprofit. Becoming a mother while in that job opened my mind to launching a breast pump bag (储奶袋) business. Now I run a highly successful company that I started up on my own. I'm not a politician!
2. Failure is critical to your success
Failure can be heartbreaking. But I will tell you that every failure I’ve had along the way has absolutely made me better.
Failing the big math exam in high school and going to summer school was embarrassing. I eventually passed, and I’ve never failed an exam again. I learned from that experience to ask for help. Now, I ask for help in business all the time.
I’m proud to be a role model to you as a mom and an entrepreneur. I hope I inspire you to believe that you can be anything you want. It will be my pleasure to watch your lives unfold before my eyes.
Love,
Your mom

D.It’s important to turn to others for help.

How I Turned to Be Optimistic
I began to grow up that winter night when my parents and I were returning from my aunt’s house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.
I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see—the strange and magical places I had known only from books and pictures. The country I was leaving never to come back was hardly in my head then.
The four years that followed taught me the importance of optimism (乐观), but the idea did not come to me at once. For the first two years in New York I was really lost-having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex (复杂的) for me. Some time passed before my stepfather and I got used to each other. I was often sad, and saw no end to “the hard times.”
My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.
From my experiences I have learned one important rule: almost all common troubles finally go away! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy.
