Teaching a child to read at a young age gives him a valuable start in life. Reading is the basic part of education and a child’s reading ability will influence his school success greatly. Learning difficulties, many of which begin from poor reading skills, can damage a school child’s confidence and affect his future achievement. Young children are programmed to learn and they can learn better with encouragement. Ten to twenty minutes of reading a day still leaves plenty of time for play.Many parents are concerned that learning to read is too challenging a task for a pre-school child, but they should also remember that most children learn to speak by the time they are 3. Learning a language is probably the single most challenging task any individual can undertake, yet children do it without formal instruction, achieving the fluency much better than adult language students.
There is a window of opportunity in terms of IQ development, which is most open during a child’s early years. A scientific study, carried out by Dr. Peter Huttenlocher at the University of Chicago, showed that the number of connectors, called synapses(神经元突触), between the nerve endings in a newborn baby’s brain is similar to the number in the average adult brain. These synapses increase rapidly during early childhood. By 12-24 months a child’s brain has about 50% more synapses than the average adult brain. After that the synapses which are not in use begin to atrophy(衰退). For most people, from age 16, the number remains steady. It begins to drop again as we move into our golden years. Doing intellectual activities at a young age, such as learning to read, can stimulate(刺激)and preserve these connectors in the brain resulting in a long-term beneficial(有益的)effect on IQ development.
Another notable study is probably the Milwaukee project. This study took a group of babies, all of whose mothers had low IQs, and gave them special training for seven hours a day, five days a week, until they started first grade. By the age of 6 these children had an average IQ 30 points higher than their contemporaries. The overwhelming conclusion is that the early intellectual stimulation can have a positive, long-term effect on a child’s brain development.
From birth you should talk to and explain things to your baby. Reading to him can be a wonderful way of spending quality time with your child. The enjoyment of books and being familiar with the idea of print will pave the way for(为……铺平道路)learning to read later.
If your child is a fast learner you can help him realize his potential by introducing him to the joy of the printed word at an early age. This will lay the foundations(基础)for both a high achieving school career and a lifelong love of reading. If your child shows early signs of reading difficulties, your efforts may help him get rid of such problems before he goes to school.
It can be difficult to teach your own child because emotional(引起情绪激动的)issues arise easily. Online programs for learning to read English are excellent options. They allow children to repeat new materials as many times as they need to, without wearing out the parents’ patience.

The designer says he came up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp,” he said.
The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors(传感器)then ensure that the umbrella offers pedestrians (行人) shelter whenever it starts raining.
In addition to the rain sensor, there’s also a 360° motion sensor on the fiberglass street lamp which detects whether anyone is using the Lampbrella. After three minutes of not being used the canopy is closed.
According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lightning strike. Each Lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.
While there are no plans to take Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department, and insists this creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.
小题1:For what purpose did Belyaev create the Lampbrella?
A.To predict a heavy rain. |
B.To check the weather forecast. |
C.To protect people from the rain. |
D.To remind people to take an umbrella. |
A.His creation was inspired by an experience. |
B.It rains a lot in the city of Saint Petersburg. |
C.Street lamps are protected by canopies. |
D.He enjoyed taking walks in the rain. |
A.motor→canopy→sensors | B.sensors→motor→canopy |
C.motor→sensors→canopy | D.canopy→motor→sensors |
A.The designer will open a company to promote his product. |
B.The Lampbrella could be put into immediate production. |
C.The designer is confident that his creation is practical. |
D.The Lampbrella would be put on show in Moscow. |
They examined differences between red squirrels and gray squirrels in the American state of Indiana. The scientists wanted to know how these differences could affect the growth of black walnut (黑胡桃) trees. The black walnut is the nut of choice for both kinds of squirrels. The black walnut tree is also a central part of some hardwood forests.
Rob Swihart of Purdue University did the study with Jake Goheen, a former Purdue student now at the University of New Mexico. The two researchers estimate that several times as many walnuts grow when gathered by gray squirrels as compared to red squirrels. Gray squirrels and red squirrels do not store nuts and seeds in the same way. Gray squirrels bury nuts one at a time in a number of places. But they seldom remember where they buried every nut. So some nuts remain in the ground. Conditions are right for them to develop and grow the following spring. Red squirrels, however, store large groups of nuts above ground. Professor Swihart calls “death traps for seeds”.
Gray squirrels are native to Indiana. But Professor Swihart says their numbers began to decrease as more forests were cut for agriculture. Red squirrels began to spread through the state during the past century.
The researchers say red squirrels are native to forests that stay green all year, unlike walnut trees. They say the cleaning of forest land for agriculture has helped red squirrels invade Indiana. Jake Goheen calls them a sign of an environmental problem more than a cause.
小题1:The study done by Rob Swihart and Jake Goheen is to ________.
A.find out the living conditions for squirrels |
B.learn squirrels’ influence on black walnut trees |
C.do something to get rid of squirrels |
D.save the forests in the American state of Indiana |
A.the way they gather the walnut |
B.the time they have winter sleep |
C.the place they have winter sleep |
D.the place they store the walnuts |
A.red squirrels eat more nuts than gray squirrels |
B.gray squirrels and red squirrels will have severe fights |
C.nuts above the ground will not develop into plants |
D.seeds can be traps for other animals in the forest |
A.The black walnut is equally attractive to both gray and red squirrels. |
B.Gray squirrels do more harm to the forest than red squirrels. |
C.Red squirrels and gray squirrels have helped the spread of walnut trees. |
D.The cleaning of forest land benefits red squirrels directly. |
In the early days of Internet marketing, online advertisers used banner (框式广告) and pop-up ads (弹出式广告) to attract customers. These techniques reached large audiences, led to many sales leads, and came at a low cost. However, a small number of Internet users began to consider these advertising techniques annoying. Yet because marketing strategies relying heavily on banners and pop-ups produced results, companies invested growing amounts of money into purchasing these ad types. As consumers became more complicated, frustration with these online advertising techniques grew. Independent programmers began to develop tools that blocked banner and pop-up ads.
A major development in online marketing came with the introduction of pay-per-click ads. Unlike banner or pop-up ads, which originally required companies to pay every time a website visitor saw an ad, pay-per-click ads allowed companies to pay only when an interested potential customer clicked on an ad. More importantly, however, these ads are not affected by the pop-up and banner blockers. As a result of these advantages and the incredible growth in the use of search engines, which provide excellent places for pay-per-click advertising, a great number of companies began turning to pay-per-click marketing. However, as with the banner and pop-up ads, pay-per-click ads came with their shortcomings. When companies began pouring billions of dollars into this emerging medium, online advertising specialists started to notice the presence of what would later be called click fraud (欺诈): representatives of a company with no interest in the product advertised by a competitor click on the competitor’s ads simply to increase the marketing cost of the competitor. Click fraud grew so rapidly that marketers sought to diversify (摆脱) their online positions away from pay-per-click marketing through new mediums.
Although pay-per-click advertising remains a common and effective advertising tool, marketers adapted yet again to the changing elements of the Internet by adopting new techniques such as pay-per-performance advertising. As the pace of the Internet’s evolution increases, it seems all the more likely that advertising successfully on the Internet will require a strategy that avoids constancy (持续性) and welcomes change.
小题1:What is the main idea of the passage?
A.The pace of the Internet’s evolution is increasing and will only increase in the future. |
B.Internet advertising fails to reach Internet users, causing ads to be blocked. |
C.The Internet has experienced dramatic changes in short periods of time. |
D.Rapid development of the Internet calls for new advertising strategies and mediums. |
A.the type of individual each medium reaches |
B.whether the medium is interactive |
C.the pace at which the medium develops |
D.the cost of advertising with each medium |
A.Using software to block competitors’ advertisements. |
B.Clicking on the pay-per-click ads of competitors. |
C.Clicking on the banner advertisements of opponent companies. |
D.Using search engine to attack the pages of competitors. |
A.It will eventually become less popular just like other forms of Internet advertising. |
B.It will not face shortcomings due to its differing approach to online marketing. |
C.Internet users will develop free software to block its effectiveness. |
D.Although it improves on pay-per-click advertising, it still suffers from click fraud. |
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch(缝合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle(脚踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical, it could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement(侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties(版税). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小题1:Barthelemy Thimonnier’s garment factory was burned down because _____________.
A.people did not know how to put out the fire |
B.Elias Howe thought Thimonnier had stolen his invention |
C.the sewing machines was couldn’t work finally |
D.workers who feared the loss of their jobs to a machine set fire |
A.Singer is an American inventor and manufacturer. |
B.The Singer sewing company became more practical. |
C.The foot treadle helped to make the sewer’s hands free. |
D.Singer made improvements to the design of sewing machines. |
A.Because the judge was against Singer for his surly attitude. |
B.Because Howe had already patented the lockstitch used by Singer. |
C.Because Singer had borrowed money from Howe and never repaid it. |
D.Because Singer and Howe had both invented the same machine. |
A.Stitch in Time Saves Nine |
B.The Case between Howe and Singer |
C.Patent Laws on the Sewing Machine |
D.The Early History of the Sewing Machine |
Researchers examined the results of 97 studies. Most of the studies were less than 10 years old. They included almost three million adults from around the world, including the United States, Canada, China, Taiwan, Brazil, India and Mexico.
The researchers at the National Center for Health Statistics found that people who are considered overweight or slightly obese were five to six percent less likely to die from all causes than people of normal weight. People with higher obesity ratings, however, had almost a 30 percent greater risk of death compared to normal-weight individuals.
Katherine Flegal was the lead author of the study. She says she was not surprised that overweight people would not have a higher risk of death.
“Because we’d actually already read a lot of this literature and realized it was likely that mortality rates (死亡率) for overweight would be at least not higher than normal weight. I guess I was a little bit surprised that it was definitely lower. And I was also surprised that the lower rates of obesity also didn’t seem to differ from normal weight.”
But she says the difference in death rates appears to be small between normal-weight people and those who are overweight or mildly obese.
The study has raised new questions about “body mass index,”(体重指数) or BMI. This is a measurement of body fat as a ratio(比率) of height to weight. In recent years, many public health experts have promoted body mass index as a way to predict the risk of health problems. Bu t a person"s BMI can be misleading in some cases.
Steven Heymsfield ,the executive director of the Pennington Biomedical Research Center, says people can be physically fit and in good health, but might weigh more because they are more muscular.
Still, Dr. Heymsfield says people should not think gaining extra weight is OK just because of the new findings. He says being at a healthy weight lowers the risk for heart disease and diabetes(糖尿病).
小题1:According to the new findings, the researchers found that __________ .
A.People with high obesity have a lower risk of early death than people with low obesity |
B.People with overweight have a greater risk of early death than people of normal weight. |
C.People with mild obesity are less likely to die than people of normal weight. |
D.People with obesity live much longer than people of normal weight. |
A.works like novels and poems |
B.books and articles on a particular subject |
C.printed material |
D.magazines and newspapers |
A.BMI is commonly used to measure body fat as a ratio of height to weight. |
B.Not all people with a little higher BMI are fat . |
C.Many public health experts encourage more people to use BMI as a way to predict the risk of health problem |
D.Because of the ne w findings, people should think about gaining extra weight. |
