Each new school year brings fresh reminders of what educators call the summer learning gap. Some call it the summer learning setback. Simply speaking, it means the longer kids are out of school, the more they forget. The only thing they might gain is weight.
Most American schools follow a traditional nine-month calendar. Students get winter and spring breaks and about ten weeks of summer vacation. Some schools follow a year-round calendar. They hold classes for about eight weeks at a time, with a few weeks off in between. The National Association for Year-Round Education says there were fewer than three thousand such schools at last count. They were spread among forty-six of the fifty states.
But many experts point out that the number of class days in a year-round school is generally the same as in a traditional school. Lead researcher Paul von Hippel said, "Year-round schools don't really solve the problem of the summer learning setback. They simply spread it out across the year."
Across the country, research shows that students from poor families fall farther behind over the summer than other students. Experts say this can be prevented. They note that many schools and local governments offer programs that can help.
But calling them "summer school" could be a problem. The director of the summer learning center at Johns Hopkins, Ron Fairchild, said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term summer school”. In American culture, the idea of summer vacation is connected to beliefs about freedom and the joys of childhood. The parents welcomed other terms like "summer camp," "enrichment," "extra time" and "hands-on learning."

小学生10分钟应用题系列答案For most people, shopping is still a matter of wandering down the street or loading a cart in a shopping mall．Soon, that will change．Electronic commerce （trade） is growing fast and will soon bring people more choices．There will, however, be a cost: protecting the consumer from being cheated will be harder．Many governments therefore want to apply street regulations to the electronic world．But politicians would be wiser to see cyberspace as a basis for a new era of corporate self-regulation．
Consumers in rich countries have grown used to the idea that the government takes responsibility for everything for the stability of the banks to the safety of the drugs or their rights to refund when goods are faulty．But governments cannot enforce national laws on businesses whose only presence is on the screen．Even in a country where a clear right to compensation exists, the on-line customer in Tokyo, say, can hardly go to New York to get a refund for a clothes purchase．
One answer is for government to cooperate more: to recognize each other’s rules．But that requires years of work and volumes of detailed rules．And plenty of countries have rules too fanciful for sober countries to accept．There is, however, another choice．Let the electronic businesses do the regulation themselves．They do, after all, have a self-interest in doing so．
In electronic commerce, a reputation for honest dealing will be a valuable competitive asset．Governments, too, may compete to be trusted．For instance, customers ordering medicines on-line may prefer to buy from the United States because they trust the rigorous screening of the Food and Drug Administration; or they may decide that the FDA’s rules are too strict, and buy from Switzerland instead．
Customers will still need to use their judgment．But precisely because the technology is new, electronic shoppers are likely for a while to be a lot more cautious than customers of the normal sort．And the new technology will also make it easier for them to complain when a company lets them down．In this way, at least, the advent of cyberspace may argue for fewer consumer protection laws, not more．
【小题1】According to the author, what will be the best policy for electronic commerce?
| A．Self-regulation by the business． | B．Strict consumer protection laws． |
| C．Close international cooperation． | D．Government protection． |
| A．Refuse to pay for the purchase． | B．Go to the seller and ask for a refund． |
| C．Appeal to consumer protection law． | D．Complain about it on the Internet． |
| A．international cooperation would be much more frequent |
| B．consumers could easily seek government protection |
| C．a good reputation is a great advantage in competition |
| D．it would be easy for consumers to complain |
| A．very quick | B．very cautious | C．very slow | D．rather careless |
| A．It will be easier for him to return the goods he is not satisfied with． |
| B．It will be easier for him to attain the refund from the seller． |
| C．It will be easier for him to get his complaints heard by other consumers． |
| D．It will be easier for him to complain about this to the government． |

CHICAGO (Reuters) - Smoking not only can wrinkle(起皱纹) the face and turn it yellow -- it can do the same to the whole body, researchers reported on Monday.
The study, published in the Archives of Dermatology, shows that smoking affects the skin all over the body -- even skin protected from the sun.
"We examined non-facial skin that was protected from the sun, and found that the total number of packs of cigarettes smoked per day and the total years a person has smoked were linked with the amount of skin damage a person experienced," Dr. Yolanda Helfrich of the University of Michigan, who led the study, said in a statement.
"In participants older than 65 years, smokers had significantly more fine wrinkling than nonsmokers. Similar findings were seen in participants aged 45 to 65 years," Helfrich's team added in their report.
The researchers tested 82 people, smokers and nonsmokers, taking pictures of the inner right arms. They ranged in age from 22 to 91 and half were smokers. Independent judges decided how wrinkled each person's skin was.
When skin is exposed to sunlight, notably（尤其）the face, it becomes coarse, wrinkled and discolored with a pale yellow tint, Helfrich's team wrote.
Several previous studies have found that cigarette smoking contributes to premature（过早的）skin aging as measured by facial wrinkles, the study said, but little has been done to measure the aging of skin not exposed to light.
The report did not discuss the mechanism involved but previous research has found that cigarette smoke, among other things, causes blood vessels（血管）beneath the skin to constrict（紧缩）, reducing blood supply to the skin.
Smoking can also damage the connective tissue (组织)that supports both the skin and the internal organs.
【小题1】The best title for this passage would be_______.
| A．The danger of smoking | B．Smoking causes skin aging |
| C．Quit smoking for health | D．A survey of smokers |
| A．smoking won’t make skin protected from the sun |
| B．smoking will do damage to skin rather than other organs |
| C．smokers over 65 usually won’t worry about their skin |
| D．the age of smokers is not connected with the result of the test |
| A．it will lower blood supply to skin | B．it can make you feel tired |
| C．it can make skin come off | D．it can make blood run faster |
| A．inform people about the result of the study |
| B．advise people how to protect skin |
| C．warn people not to smoke again |
| D．introduce a new way of avoiding skin aging |
