Indoor Pollution1 So you think that by staying at home you are safe from all the terrible kinds of pollution present outdoors, such as in or near factories, roads, and garbage dumps? Do you think that by staying in your office you are breathing cleaner, safer air than when you go outside for lunch or are on the way back home from work? Think again. Recent research done at the University of Texas has shown that staying indoors may actually be more harmful to one's health than being outdoors in smoggy cities.2 Apparently, we are safe neither at home nor in the business office. We use water in both places, but the above-mentioned 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 such seemingly harmless activities as cleaning one's house. These additives are released from water by daily actions like water running out of faucets, spraying from garden hoses, or splashing in dishwashers and washing machines. As the water is agitated, these chemicals are released into theair and then breathed in. Once inside our bodies, they start to affect our health adversely.3 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 candles and incense release a lot of things which have beenproven as harmful to health as working or living near high density traffic. New rugs, 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 and their peripherals release polluting chemicals, too. As offices and homes often have inadequate ventilation, these chemicals can build up to become health nuisances. Their toxic effects are only now being slowly recognized.4 These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise precaution. Home and office windows should be opened during good weather to allow a flushing of stale air. Even one's car need to be ventilated as well as the garage.5 We need further research to understand better other potential health hazards, too. For example, the effects of overcrowding of schools (carbon dioxide build up), factory work environments (an endless list of potentially dangerous substances), and even home heating and cooling (the furnace and air conditioner may be our enemies, not our fiends) 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".(1) (判断题)Recent research done at the University of Texas shows that staying indoors is sometimes harmful.正确错误(2) (判断题)Using water to clean one's house can be potentially harmful.正确错误(3) (判断题)The additives in the water supply may do harm to our skin when we water gardens.正确错误(4) (判断题)The authors suggests that to remove indoor pollution we need to ventilate the garage.正确错误(5) (判断题)People have long understood that air conditioners can be our enemies.正确错误

Everybody would love to make lots of money quickly, working from home, and only doing a few hours of work per week. I've spent the past two years trying to find a great way of doing this. Only over the course of the past few months have I found any "get rich quick" programs worth buying. I've been trying to make money online for a long time. I had a few small websites, but they never made much more than a few hundred per month. It was easy money and didn't require much work on my part, but I knew there were people out there doing better than I was and I knew I could do as well as them. Now, I've seen a lot of "get rich quick" programs. Most of these people make claims about earning 2, 000perdaywithG oogleorsomethin gsimilarlycrazy. .Almostallofthe sepeopleare completeliars. Eveni,ftheyweremaking2,000 per day with Google absence, it'd be because they had high-traffic websites with a lot of quality content. I'd know, because in one whole month, I never even made half of what they promised I'd make daily with their programs. Anyway, I finally got sick of what was being offered. I decided I'd look through all of the "get rich quick" programs I could find and see if there were any that were actually reasonable. I found that there were owners selling their programs for well over 100, but the information in them could be found almost anywhere online for free. Additionally, they all contained out-of-date information, had no e-mail support, no money back guarantees, and broken links in the downloads section. In conclusion, almost all of the programs I found were completely useless. The owners knew it, but they couldn't care less about their customers since they didn't offer refund (退款) policies! Amazingly, while looking through all of the programs, I actually did find a few practical programs. They were run by ordinary people like you and me, and they had found some great methods of making money from their home by doing very little work. I spent some time working with those programs, and my income is now ten times what it used to be.1. What is the ideal way of making money for people?A) Doing a few hours of work in the office.B) Doing long hours of work in the office.C) Doing a few hours of work at home.

B) Working for some websites.C) Making as much money as he wanted.D) Looking for a well-paid job.3.

What did the writer find about the "get rich quick" programs?A) The information was new.B) They were very expensive.C) They offered e-mail support.D) They were not reliable. 5. What can we infer from the last paragraph?A) A few of the programs are reliable though most are not. B) Few of the programs the writer found were useless.C) Most owners promise refund if the programs don't work.D) All programs run by ordinary people are practical.
