Scratchy throats, stuffy nos and body aches all spell miry, but being able to tel1 if the cau is a cold or flu may make a difference in how long the miry lasts.
The American Lung Association (ALA) has issued new guidelines on combating colds and the flu, and one of the keys is being able to quickly tell the two apart. That's becau the prescription drugs available for the flu need to be taken soon after the illness ts in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come.
元宵晚会主持词 The common cold and the flu are both caud by virus. More than 200 virus can cau cold symptoms, while the flu is caud by three virus—flu A, B and C. There is no cure for either illness, but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA.
But if the flu does strike, quick action can help. Although the flu and common cold have many similarities, there are some obvious signs to look for.
Cold symptoms such as stuffy no, runny no and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more vere than cold symptoms.
The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advis parents to call the doctor if their small children have flu-like symptoms.
Both cold and flu symptoms can be ead with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief becau of the risk of Reye syndrome, a rare but rious condition of the liver and central nervous system.
There is, of cour, no vaccine for the common cold. But frequent hand washing and av
oiding clo contact with people who have colds can reduce the likelihood of catching one.

In a time of low academic achievement by children in the United States, many Americans are turning to Japan, a country of high academic achievement and economic success, for possible answers. However, the answers provided by Japane preschools are not the ones Americans expected to find. In most Japane preschools, surprisingly little emphasis is put on academic instruction. In one investigation, 300 Japane and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education. Only 2 percent of the Japane respondents listed "to give children a good start academically" as one of their top three reasons for a society to have preschools. In contrast, over half the American respondents cho this as one of their top three choices. To prepare children for successful careers in
first grade and beyond, Japane schools do not teach reading, writing, and mathematics, but rather skills such as persistence, concentration, and the ability to function as a member of a group. The vast majority of young Japane children are taught to read at home by their parents.
In the recent comparison of Japane and American preschool education, 91 percent of Japane respondentscho providing children with a group experience as one of their top three reasons for a society to have preschools. Sixty-two percent of the more individually oriented Americans listed group experience as one of their top three choices. An emphasis on the importance of the group en in Japane early childhood education continues into elementary school education.
Like in America, there is diversity in Japane early childhood education. Some Japane kindergartens have specific aims, such as early musical training or potential development. In large cities, some kindergartens are attached to universities that have elementary and condary schools.
Some Japane parents believe that if their young children attend a university-bad pr
ogram, it will increa the children's chances of eventually being admitted to top-rated schools and universities. Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japane kindergartens.
6. We learn from the first paragraph that many Americans believe ______.
A.Japane parents are more involved in preschool education than American parents
B.Japan's economic success is a result of its scientific achievements
C.Japane preschool education emphasizes academic instruction
D.Japan's higher education is superior to theirs
答案：C
7. Most Americans surveyed believe that preschools should also attach importance to ______.
A.problem solving
蝴蝶谜语B.group experience
C.parental guidance
D.individually-oriented development
答案：B
8. In Japan's preschool education, the focus is on ______.
A.preparing children academically
B.developing children's artistic interests
C.tapping children's potential
D.shaping children's character
答案：D
9. Free play has been introduced in some Japane kindergartens in order to ______.

楚辞是谁写的 Lead deposits, which accumulated in soil and snow during the 1960s and 70s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas u in the United States, the lead accumulation world-wide has decread significantly.
A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued rearch led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Rearch in France. A study by Dr. Boutron published in
1991 showed that lead levels in arctic snow were declining.
In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline ud in the United States were different from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.
In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeastern United States had decread markedly since the introduction of unleaded gasoline.
Many scientists had believed that the lead would stay in soil and snow for a longer period.
The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment procesd and redistributed the lead faster than the scientists had expected.
Scientists say both studies demonstrate that certain parts of the ecosystem respond rapidly to reductions in atmospheric pollution, but that the findings should not be ud as a licen to pollute.
