题目列表(包括答案和解析)
Apparently，we are safe neither at home nor in the business office.We use water in both places，but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap，spraying from garden pipes，or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.
We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”

Children are our future, and it’s up to us to arm them with the tools to succeed. Sadly, today’s children are being armed with more dangerous tools like weapons （武器）, drugs and gangs. Once a relatively peaceful environment, many schoolyards of today are becoming unsafe for both students and teachers.
Home schools are available to give you choices. Home schooling provides top-quality education, flexibility, and freedom to create your own schedule. At Heritage Home School we believe the choice should be yours. Thanks in part to modern technology, home schooling information is becoming readily available across our nation. A recent study by the ITBS （Iowa Tests of Basic Skills） and TAP （Tests of Achievement and Proficiency） shows us that students of home schools do particularly well when compared with the nationwide average. In every subject at every grade level, students of home schooling scored obviously higher than those in public and private schools.
If you’re new to home schooling, you may be asking yourself, “Will home schools really work for my children?”
Fact: A nationwide study using a random（任意）selection of 1,516 families found students of home schooling to be scoring, on average, at or above the 80th percentile in all areas on standardized achievement test.
Note: The national average on standardized achievement tests is the 50th percentile. Collectively, the staff at Heritage Home School brings 65 years of experience in home schooling curriculum. We’ve placed students in the top 2 % of the nation in math and many are successfully moving on to college.
One study found that of the home schooled adults, 0% were unemployed, 0% were on welfare and 94% said home education prepared them to be independent persons. For more home schooling information, call us today toll free at（877）532-7665.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。
Is bottled water better for you than tap? Or should you choose vitamin-enriched water? Experts say, skip it all．None of these products is likely to make you any healthier．Below, we look at four major myths about the benefits of drinking water． 1 Experts say there’s an easy way to judge．If you are not thirsty, your fluid intake is likely “just right”
Myth No 1：Drink eight glasses each day．
Scientists say there’s no clear health benefit of drinking so much water a day． 2 “Nobody really knows,” says Dr．Stanley Goldfarb, a kidney expert at the University of Pennsylvania．
Myth No．2：Lots of water equals healthier skin．
The body is already 60 percent water． 3 Adding a few extra glasses of water each day has a limited effect．“It’s such a tiny part of what’s in the body,” says Goldfarb．“ It’s very unlikely that one’s getting any benefit．”
Myth No．3： 4
A more accurate statement may be：Drinking water is a helpful tool for dieters．“Water is a great strategy for dieters because it has no calories,” says Madeline Fernstrom of the University of Pittsburgh．“So you can keep your mouth busy without food and get a sense of satisfaction．” But water is not magical, she adds．“Other zero-calorie options such as diet sodas are fine, too．”
Myth No．4：It’s easy to get dehydrated(脱水的)during a workout．
Dehydration sets in when a person has lost 2 percent of his or her body weight． 5 “It’s also obvious that individuals in hot, dry climates have an increased need for water,” says Goldfarb．“But for a walk in the park, no water bottle is necessary．”
A．So where does the standard advice come from?
B．But it’s unclear whether these changes are clinically significant．
C．So for a 200-pound man, this means losing 4 pounds of water．
D．Drinking extra water leads to weight loss．
E．Drink as much water as you can．
F．So, if you take a 200-pound man, he’s 120 pounds of water．
G．But first, how do you know if you’re drinking enough water?
