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 rod 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 elbow. Day after day we practiced, and she praised me for every rung I reached. I’ll 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 boys 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 faint and cracking. I peeked out from my covers 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.

Scientists are uncovering the secrets of two port cities lost under the waters of the Mediterranean Sea, a researcher said yesterday.
Herakleion and Menouthis were rich and proud cities until something reduced them to rubble (碎石) and buried them in the mud beneath 30 feet of sea water, French underwater explorer Franck Goddio said at the American Geophysical Union conference.
“This is a mystery that is ongoing,” said Goddio, a founder of the European Institute of Marine Archeology, a Paris-based underwater research organization backed by the wealthy Hilti Foundation of Liechtenstein(列支敦士登基金会).
The destruction of the twin port cities has haunted Goddio ever since he happened upon the site about 15 miles from Alexandria while exploring sunken ships from Napoleon’s fleet.
Goddio and his group of expert divers, marine archeologists(海洋考古学家) and others, are using high powered vacuums, satellite navigation systems and sophisticated sonar(声纳) to excavate(挖掘) the sunken cities from underneath a carpet of silt about one meter (three feet) high.
Walls of shops, remains of streets and gold artifacts have been found and recovered.
Some experts believe that the port cities were destroyed by a series of massive earthquakes, much like the quakes scientists believe felled Troy(特洛伊城), Jericho and other ancient cities. The uniform direction of the collapsed columns and walls suggest an earthquake, Goddio said, but no fault lines have been found nearby.
Other researchers believe a massive wave, caused by either an offshore earthquake or a distant underwater landslide, could explain the catastrophe. Still others think rising seas and a shift in the Nile River outlet doomed the cities.
“The argument, as you can see, continues,” Goddio said.The reason why the two port cities disappeared under the waters of Mediterranean Sea is that ______.
A.the two port cities were destroyed by huge earthquakes |
B.the disappearance of the two port cities was caused by underwater landslide |

B.the two cities belonged to France |
C.some mysterious creatures from other planets destroyed the two cities |
D.the American Geophysical Union conference was once held in one of the two cities |

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. reseachers 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(怀孕) 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. |

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. |

Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient —no matter where he or she may be.
Online doctors offering advice based on normal symptoms(症状) are the most obvious example. Increasingly, however, remote diagnosis(远程诊断) will be based on real physiological data(生理数据) from the actual patient. A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone, it is perfectly practical to send a patient’s important signs over the telephone. With this kind of equipment, the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural(countryside) care. And at least one team wants to use telemedicine as a tool for disaster need—especially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts’ opinions.
But there is one problem. Bandwidth(宽带) is the limiting factor for sending complex(复杂的) medical pictures around the world — CT photos being one of the biggest bandwidth users. Communication satellites may be able to deal with the short-term needs during disasters such as earthquakes or wars. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts’ opinions and diagnosis are common. The writer chiefly talks about _______.
A.the use of telemedicine | B.the on-lined doctors |
C.medical care and treatment | D.communication improvement |
The basis of remote diagnosis will be _______.
A.personal data assistance |
B.some words of a patient |
C.real physiological information |
D.medical pictures from the Internet |
Which of the following statements is true according to the text?
A.Patients don’t need doctors in hospitals any more. |
B.It is impossible to send a patient’s signs over the telephone. |
C.Many teams use telemedicine dealing with disasters now. |
D.Broadband communications will become cheaper in the future. |
The “problem” in the fourth paragraph refers to the fact that _______.
A.bandwidth isn’t big enough to send complex medical pictures |
B.the second-generation of Internet has not become popular yet |
C.communication satellites can only deal with short-term needs |
D.there is not enough equipment for spreading the medical care |
With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物种). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & M’s College of Veterinary Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.
It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.
This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.” The aim of “Noah’s Ark” project is to _______.
A.make efforts to clone the endangered pandas |
B.save endangered animals from dying out |
C.collect DNA of endangered animals to study |
D.transfer the nuclear of one animal to another |
According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.
A.available panda eggs | B.host animals |
C.qualified researchers | D.enough money |

Language learning begins with listening. Children are greatly different in the amount of listening they do before they start speaking, and later starters are often long listeners. Most children will “obey” spoken instructions some time before they can speak, though the word “obey” is hardly accurate as a description of the eager and delighted cooperation usually shown by the children. Before they can speak, many children will also ask questions by gesture and by making questioning noises.
Any attempt to study the development from the noises babies make to their first spoken words leads to considerable difficulties. It is agreed that they enjoy making noises, and that during the first few months one or two noises sort themselves as particularly expressive as delight, pain, friendliness, and so on. But since these can’t be said to show the baby’s intention to communicate, they can hardly be regarded as early forms of language. It is agreed, too, that from about three months they play with sounds for enjoyment, and that by six months they are able to add new words to their store. This self-imitation(模仿) leads on to deliberate(有意的) imitation of sounds made or words spoken to them by other people. The problem then arises as to the point at which one can say that these imitations can be considered as speech.
It is a problem we need to get our teeth into. The meaning of a word depends on what a particular person means by it in a particular situation; and it is clear that what a child means by a word will change as he gains more experience of the world. Thus the use, at seven months, of “mama” as a greeting for his mother cannot be dismissed as a meaning-less sound simply because he also uses it at another time for his father, his dog, or anything else he likes. Playful and meaningless imitation of what other people say continues after the child has begun to speak for himself. I doubt, however, whether anything is gained when parents take advantage of this ability in an attempt to teach new sounds.Before children start speaking _______.
A.they need equal amount of listening |
B.they need different amounts of listening |
C.they are all eager to cooperate with the adults by obey spoken instructions |
D.they can’t understand and obey the adult’s oral instructions |
Children who start speaking late _______.
A.may have problems with their listening |
B.probably do not hear enough language spoken around them |
C.usually pay close attention to what they hear |
D.often take a long time in learning to listen properly |
A baby’s first noises are _______.
A.an expression of his moods and feelings |
B.an early form of language |
C.a sign that he means to tell you something |
D.an imitation of the speech of adults |
The problem of deciding at what point a baby’ imitations can be considered as speech _______.
A.is important because words have different meanings for different people |
B.is not especially important because the changeover takes place gradually |
C.is one that should be properly understood because the meaning of words changes with age |
D.is one that should be completely ignored(忽略) because children’s use of words is of-ten meaningless |
The speaker implies _______.
A.parents can never hope to teach their children new sounds |
B.children no longer imitate people after they begin to speak |
C.children who are good at imitating learn new words more quickly |
D.even after they have learnt to speak, children still enjoy imitating |
