EAlthough we already know a great deal about flu, and although the World Health Organization is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be.
There are three kinds of flu virus, known as A, B and C. Flu C virus is relatively stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies (抗体) which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability(可变性) is less developed in the flu B virus, which affects only human beings. Flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918 and 1919, when about half the world’s population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence (病毒性), the ease with which it can be transmitted and the strength of the opposition it encounters (遇到). Scientists, however, have a reliable general picture of the world situation.

An inventor seeks to create a new product that serves a specific need and fulfills a role that other products do not. Sometimes an inventor comes up with a wholly new idea, but more often inventions are simply improvements on an older design. With a little imagination and creativity (创造力), an old idea can suddenly become something new.
However, creating a new invention means much more than having a brilliant idea. A good designer follows the design process: identifying the challenge, researching and brainstorming ideas(集思广益), designing a solution, testing and evaluating the ideas, and finally building the product. Designers also use science, math, technology, and engineering to design a tool that satisfies the need they identified.
Anyone can be an inventor —even kids! For example, Chester Greenwood was just fifteen years old when he invented a product that changed his life. In fact, his idea was so good that his invention supported him for the rest of his life. You may not know his name, but you probably know his invention —earmuffs (保暖耳罩)!
The inspiration for his earmuff design came to Chester when he was ice-skating. His ears were cold, and he decided to find a way to keep them warm. With the help of his grandmother, he made a new product to protect his ears and at the age of eighteen, Chester patented his earmuff design.
Many other famous inventors started young as well. Margaret Knight —the inventor of the flat-bottomed brown paper bag —is said to have created a safety device for textile looms(织布机) when she was just twelve years old. Another example is Thomas Edison, one of the greatest inventors in history, who applied for his first patent when he was just twenty-one years old. Over the course of his life, Thomas Edison patented a total of 1,093 inventions! In most cases, an invention ________ according to the first paragraph.
A.comes from a complete new idea |
B.is usually based on an old product or idea |
C.will change its creator’s life completely |
D.is created by scientists in different fields |
The second paragraph mainly wants to tell us _______.
A.the difficulty in making a new invention |
B.the common steps of creating new things |
C.having a good idea is the key to creation |
D.designing a tool is the first step in inventing |
The example of Chester Greenwood is used to show that ________.
A.children can also invent something |
B.it is easy even for children to make inventions |
C.kids have more advantages in inventing things |
D.to be an inventor is the best way to change one’s life |
At first Chester designed his earmuffs in order to ________.
A.protect his ears while ice-skating |
B.earn money to support his poor family |
C.realize his dream of becoming an inventor |
D.make himself look fashionable while ice-skating |

Uncle Tom gave little Vicki Black a birthday gift one week before her birthday. He told her not to open it until her birthday. She knew her mother wouldn’t tolerate any disrespect to the kind man who helped them out after Vicki’s father passed away; besides, Vicki didn’t want Uncle Tom to get angry. But little Vicky didn’t want to just hold it and guess what was in it. After all, she looked forward to his coming to show her interesting things, like how to turn an old sock into a doll.
All the day, Vicki couldn’t stop thinking about the gift while her teacher was giving a lecture. Vicki sat still in her seat, drawing paper dolls inside the box. When school was done, she raced home. Walking into the room, again, she shook the present, but she heard nothing. Holding her breath, she opened the box and looked inside. Seconds later, she cried. When Mrs. Black saw the box, she said angrily, “Didn’t I tell you to leave it alone?” Vicki sobbed and said, “Mommy, you don’t understand.”
“Don’t cry to me. You have missed everything now, just because you couldn’t wait,” Mrs. Black accused. “What will Uncle Tom think now?”
“Uncle Tom gave me nothing,” Vicki cried and handed the empty box to her mother. “He played a trick on me.”
Mrs. Black said doubtfully, “Uncle Tom is not like that. You must have dropped it.”
Vicki kept crying. Only a rapid knock on the door made the house quiet. It was Uncle Tom. He looked at the empty box. “You have already done it? I told you to wait for your birthday.”
“You didn’t give me a gift.” Fresh tears filled her eyes.
“I try to give you something. I know your birthday is a special day. I tell myself to give you something valuable to last your whole life. I think hard and get the idea to give you an important lesson. If you open it on birthday, I see you learn. Then I will make a big party to celebrate. Maybe next year you listen and then you will understand the gift better.
Vicki’s cheeks flushed(脸红).
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. The quantifying ability refers to the ability to .
A.choose between different substances | B.describe the quantity of something |
C.get much knowledge of the world | D.obtain math-related skills |
What is mainly talked about in Paragraph 4?
A.The process of doing research. | B.The final choice of infants. |
C.The scientific findings. | D.The observation of infants’ behavior. |
Babies choose the larger amount of food .
A.through their natural abilities | B.with the help of parents |
C.on personal preference | D.by saying numbers |
We can learn from the text that .
A.some parents don’t care about their kids |
B.scholars disagree on baby-training programs |
C.little research has been done on infants |
D.people used to think the world is known to babies |
What’s the best title of the text?
A.Unique Quantifying Methods | B.Amazing Baby-training Ideas |
C.Early Human Abilities | D.Breakthrough in Baby Studies |
TAIBEI - Increasing numbers of Taiwanese students are joining the island’s “China rush”, seeking education on the Chinese mainland.
According to official Chinese figures, the number of Taiwanese students admitted into college and postgraduate(研究生)programs on the mainland totaled 461 in 1996, 928 in 1997 and 839 in 1998.Although no latest official numbers were available,” Netbig.com said this number had risen between 30 to 50 percent annually in the past two years with well over 1000 entering mainland campuses last year.
The Internet site, based in the Chinese city of Shenzhen, provides education service and information on Chinese mainland college and universities. “Many Taiwanese believe a Chinese education giving more knowledge about the people and culture in the mainland will increase their chances in the Chinese job market,” Netbig.com vice-president Ingrid Huang said.“I believe it will give me hands-on experience in the business field in the Chinese mainland and a better understanding of the Chinese mainland people,” said Lydia Chang, a 19-year-old majoring in journalism at Shih Shin University. Chang plans to go on to get a master’s degree in business administration in Shanghai, which she says offers the best environment for such studies.
A journalism graduate student, surnamed Lin, at the National Taiwan University said he would like to study law on the Chinese mainland since “there will be better career prospects now that more Taiwanese companies are going there”. “They hope the children could build up connections which could later become useful in their business operations,” said Yang Ching-yao, professor of the Chinese mainland studies. A Netbig.com survey showed the campuses favored by Taiwan students included Beijing, Qinghua and Renmin universities in Beijing, and Jinan and Zhongshan universities in Guangzhou. The most popular studies were law, business and Chinese medicine.
At present, Chinese Taibei doesn’t recognize diplomas earned in the Chinese mainland nor help with any inquiries about studying there. But recognizing the trend, education authorities are giving a final form to a policy accepting certificates(证书)from selected universities.One Taiwanese students study on the Chinese mainland because ___________.
A.Taiwan will reunite with the mainland sooner or later |
B.the fees asked for are lower than those of Taiwan |
C.there are many famous universities for them to choose |
D.what they have learned on the mainland will bring them a bright future |
Some business executives were sending their children to study in the Chinese mainland so that their children _______.
A.could receive better education | B.could do well in the business operations |
C.could learn more about the policy there | D.could make more friends there |
The underlined word “it” in the third paragraph refers to __________.
A.Netbig.com | B.the Chinese job market |
C.a Chinese education on the mainland | D.the university |
The author wrote the article to tell us ______________.
A.the number of Taiwanese students going to universities on the mainland had been increasing year after year |
