How to Prevent Dehydration
When the weather’s warm, you need to make sure you drink enough water. But did you know that you lose your sense of thirst as you get older? This means you're more likely to become dehydrated, making you more prone to (有傾向) falls, heart disease, urinary-tract infections, kidney stones and confusion. A study from Loughborough University in the UK has shown that drivers who had only a little water an hour made twice as many mistakes as motorists who were properly hydrated. In fact, they made a similar number of errors to what you’d expect from someone over the drink-drive limit.
So how do you know when you’re dehydrated? Warning signs include:
*Feeling tired
*Dry mouth and dry skin
*Dark urine
*Reduced appetite (食欲)
*Reduced concentration
*Headache
*Constipation.
But you might not notice any symptoms (癥狀)at all，so to make sure you stay hydrated:
*Keep a glass of water by your side when you’re at home, and drink it regularly.
*Form a new drinking habit—for example, when watching TV, always reach for the water glass during an ad break.
*Take a small bottle of water with you when you go out.
*Always drink a large glass of water with a meal.
*Eat fruit and vegetables with high water content.
*Draw up a weekly water card—a bit like a coffee loyalty card—with a target of eight glasses of water a day. Mark it every time you have a glass of water. Award yourself a prize when ifs full at the end of the week,
*Drink water before, during and after you take any exercise.

【1題詳解】
猜測詞義題。根據(jù)第一段第一句“When the weather’s warm, you need to make sure you drink enough water. But did you know that you lose your sense of thirst as you get older? This means you’re more likely to become dehydrated,…”可知，當(dāng)天氣暖和時，你需要確保你喝足夠的水。但是你知道隨著年齡的增長你會失去口渴感嗎？所以你沒有了口渴的感覺，可能就會導(dǎo)致身體“缺水”。以及第二段“So how do you know when you’re dehydrated?”下面的內(nèi)容可知，都是人“脫水”的癥狀。由此可推斷出劃線詞為 “dehydration”意為“脫水”。故選A。
【2題詳解】
細(xì)節(jié)理解題。根據(jù)第一段“But did you know that you lose your sense of thirst as you get older? This means you're more likely to become dehydrated, making you more prone to (有傾向) falls, heart disease, urinary-tract infections, kidney stones and confusion.”脫水意味著你更容易脫水，使你更容易跌倒、心臟病、尿路感染、腎結(jié)石和精神錯亂？芍“跌倒、心臟病、尿路感染、腎結(jié)石”屬于身體上的毛病，“精神錯亂”為精神上的疾病？芍撍畷䦟(dǎo)致身心問題。故選D。
【3題詳解】
細(xì)節(jié)理解題。根據(jù)文章中的“when watching TV, always reach for the water glass during an ad break.Take a small bottle of water with you when you go out.Always drink a large glass of water with a meal….Mark it every time you have a glass of water.”可知，看電視時在廣告間隙伸出手拿杯子喝水，出去的時候帶上一小瓶水。吃飯時一定要喝一大杯水…要做到隨時手邊有水。由此可知，為確保你保持水分充足，要隨時都能喝到水。分析選項(xiàng)可知B符合題意，故選B。
