四、閱讀測驗I：24% ( @ 2分)Contrary to conventional wisdom, some scientists suggest that it may be healthier for people not to tidy their beds after they wake up in the morning. According to their recent research, the dust mites living in our mattresses dislike messy and unmade beds, which could be good news for people suffering from asthma. The research team reported that since the dust mites live off the moisture and sweat from our bodies, they could only survive in sheets and mattresses that were slightly damp. An unmade bed allows air to circulate between the sheets and dry them out. If the sheet are dry, the creatures will die from dehydration. The researchers also pointed out that on average there are around 1.5 million dust mites on a bed, which are less than a millimeter long, feeding on the flakes of skin that fall from human body.These researchers are cautiously optimistic that the research could reduce the amount of money spent on treating illness caused by dust mites. People often breathe in the waste produced by bed bugs or get bitten by them, which can result in asthma and other illnesses. It’s estimated that it currently costs the British health service more than one billion dollars to treat mite-related illnesses annually. The researchers also believe that their findings may help building designers create healthy homes and healthcare workers recognize environments most threatened by mites. An allergy expert also said that it would be good news if new ways were discovered to modify the home so as to reduce mites.
