Many of the world’s pollution problems have been caused by the crowding of large groups of people into the cities. Supply for the needs of the people leads to further pollution by industry. If the rapid increase of world population in countries continues at the present rate, there may be much greater harm to human beings. Some scientists speak of the increase in numbers of people as “population pollution.”
About 2,000 years ago, the world population was probably about 250 million. It reached a billion in 1850. By 1930 the population was two billion. It is now three and a half billion. It is expected to double by the year 2,000. If the population continues to grow at the same rate, there will be 25 billion in the world a hundred years from now.
Man has been using the earth’s resources more and more rapidly over the past years. Some of them are almost used up. Now many people believe that man’s greatest problem is how to control the growth of the population. The material supplies in the world will be far from enough to support the human population in time to come, if the present rate of increase continues. Already there is overcrowding in many cities and starvation in some countries. Should man’s population keep on growing so rapidly as before? Many people believe that human survival in the future depends on the answer to this question.The rapid increase in population is considered to be __________.
A.the increase of resources | B.population pollution |
C.the development of mankind | D.the present rate |
If the present rate of increase continue, ________________.
A.the world is going to end |
B.the earth won’t be able to support the growing population in the future |
C.pollution has nothing to do with the rapidly increasing population |
D.there would be four billion in the world a hundred years from now |
Which of the following is Wrong according to the passage?
A.In 1850 the world population reached a billion. |
B.Man must fight a battle against population pollution. |
C.The world’s population is increasing with years. |
D.All of the earth’s resources are gone now. |
Even before my father left us, my mother had to go back to work to support our family.Once I came out of the kitchen, complaining, “Mom, I can't peel potatoes.I have only one hand.”
Mom never looked up from sewing."You get yourself into that kitchen and peel those potatoes," she told me. “And don't ever use that as an excuse for anything again!”
In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel bar to the next.When it was my turn, I shook my head.Some kids behind me laughed, and I went home crying.
That night I told Mom about it.She hugged me, and I saw her "we'll see about that" look. The next afternoon, she took me back to school.At the deserted playground, Mom looked carefully at the bars.
"Now, pull up with your right arm," she advised.She stood by as I struggled to lift myself with my right hand until I could hook the bar with my other arm.Day after day we practiced, and she praised me for every rung (横档) I reached.I'd never forget the next time, crossing the rungs.I looked down at the kids who were standing with their mouths open.
One night, after a dance at my new junior high, I lay in bed sobbing.I could hear Mom come into my room."Mom," I said, weeping, "none of the girls would dance with me."
For a long time, I didn't hear anything.Then she said, "Oh, honey, someday you'll be beating those boys off with a bat." Her voice was soft and weak.I glanced at her to see tears running down her cheeks.Then I knew how much she suffered on my behalf.She had never let me see her tears.Which of the following expressions can be used most suitably to describe Mom's attitude when she made the child peel potatoes?
A.Cruel. B.Serious. C Strict. D.Cold.From the passage, we know monkey bars can help a child train ____.
A.the skill to circle round a bar |

B.What the child had said brought Mom great attraction and curiosity. |
C.Mom was determined to prove she herself was better than the teacher. |

Parents are often amazed at how fast their child grows and develops. New research has determined that the ability to quantify may develop much sooner than most parents realize.
Kristy vanMarle, professor of the University of Missouri, has determined that contrary to what previous studies have shown, infants(婴儿)are able to quantify substances(物质)—like sand or water—as early as 10 months. As long as the difference between the two substances is large enough, infants will choose the larger amount, especially when it comes to food.
With the assistance of her team researchers, vanMarle tested the quantifying skills of babies by presenting them with two cups: one containing a small amount of food, and one containing a larger amount. Consistently, the babies chose the larger amount.
“Several studies throughout the last 15 years have shown that infants are very good at telling how many objects they see; however, infants don’t seem to count things like water or sand,” vanMarle said. “What we’re saying is that they can quantify substances; it’s just much harder. The infants can see how much food goes into each cup and compare that in their memories. They decide which amount is larger, and they almost always select the larger one.”
This information further refutes(驳斥)the long-held idea that babies “know nothing of the world,” vanMarle said.
“Since psychologists have begun studying infants with sensitive measures, we’ve discovered a lot of early abilities. I think for parents, it should be exciting to know that there’s somebody in there that has some fundamental and basic knowledge of the world, and that knowledge is guiding their development,” vanMarle said.
In the future, vanMarle says this kind of study could be linked to a child’s progress in math-related skills, although programs marketed to increase those abilities, such as “Baby Einstein,” still have mixed reviews when it comes to academic study.

Motherhood may make women smarter and may help prevent dementia (痴呆) in old age by bathing the brain in protective hormones (荷尔蒙) , U.S. researchers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s (早老痴呆症). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
“Our research shows that the hormones of pregnancy are protecting the brain, including estrogen (雌激素), which we know has many neuroprotective (保护神经的) effects,” Kinsley said.
“It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview. “They go through pregnancy and hormonal changes.”
Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline.
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.
“They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations (改变) to the brain.” How do scientists know “Motherhood may make women smarter”?
A.Some researchers have told them. |
B.Many women say so. |
C.They know it by experimenting on rats. |
D.They know it through their own experience. |

What can protect the brain of a woman according to the passage?
A.Estrogen. | B.The hormones of pregnancy. |
C.More exercise. | D.Taking care of children. |
“It’s rat data but humans are mammals just like these animals are mammals.” What does the sentence suggest?
A.The experiments on the rats have nothing to do with humans. |
B.The experiments on the rats are very important for animals. |
C.The experiments on the rats are much the same on humans. |
D.The experiments on the rats are much the same on other animals. |
