Question

【題目】Symptoms of Dehydration(脫水)

You’re bad- tempered.

Researchers tested the mood and concentration of 25 women who drank healthy amounts of water one day, and then didn’t over the next two days. When slightly dehydrated, the women reported tiredness, bad temper, headaches, and difficulty focusing. In a separate test, men with mild dehydration also had trouble with mental tasks. 【1】 Scientists are still trying to figure out why.

You have a bad workout.

【2】 It impacts how much you can push yourself. Even a 2 to 3 percent fluid loss affects your ability to get a good workout and more than 5 percent dehydration decreases exercise capacity by about 30 percent. A no-brainer way to avoid dehydration and dehydration symptoms is to aim for this much water per day.

【3】

Driving while dehydrated may be just as dangerous as getting behind the wheel drunk, in terms of how many mistakes you could make on the road. British researchers had participants take two-hour drives [using a simulator (模擬器). When they drank enough water, there were 47 driving errors. 【4】

You feel dizzy when you stand up too fast.

One of the signs of dehydration is when your blood volume and pressure drops, it can leave you feeling dizzy or faint, or bring on that rush of light-headedness after you quickly get up from sitting or lying down.

The exact treatment for dehydration symptoms depends on age and how severely dehydrated someone is. 【5】 Most of the time, however, people use some over-the-counter solutions for kids, and adults can drink more water

A. You drive like you’re drunk.

B. Dehydration can be life-threatening.

C. To get rid of dehydration you have to replace lost water.

D. In extreme cases, people might go to the hospital for a treatment.

E. Dehydration reduces blood pressure and makes the heart work harder.

F. But when it came to mood changes, women changed much more than men’s.

G. But when they are short of water, there were more than doubled driving errors to 101.

【5】D

【解析】

本文是一篇說明文。文章介紹的是脫水的4種癥狀，即你會(huì)脾氣暴躁；你會(huì)鍛煉得不好；你開車就像喝醉了一樣；你起身太快會(huì)感到頭暈。

【1】根據(jù)上文In a separate test, men with mild dehydration also had trouble with mental tasks.可知，在另一項(xiàng)單獨(dú)測(cè)試中，輕度脫水的男性也有精神問題。此處承接上文說明女性的表現(xiàn)。故F選項(xiàng)“但在情緒變化方面，女性的變化要比男性大得多”符合上下文語境，故選F。

【2】根據(jù)后文It impacts how much you can push yourself.可知它會(huì)影響你對(duì)自己的要求。可推知，本句是在說明脫水會(huì)引起的身體不適，從而導(dǎo)致鍛煉得不好。故E選項(xiàng)“脫水會(huì)降低血壓，使心臟工作更加困難”符合上下文語境，故選E。

【3】由后面的Driving while dehydrated may be just as dangerous as getting behind the wheel drunk.可知開車時(shí)脫水可能和酒后駕車一樣危險(xiǎn)。由此可知，開車時(shí)脫水會(huì)讓你像喝醉了一樣，故A選項(xiàng)“你開車就像喝醉了一樣”符合上下文語境，故選A。

【4】根據(jù)前面的When they drank enough water, there were 47 driving errors可知，當(dāng)他們喝足夠的水時(shí)，有47個(gè)駕駛失誤。此處承接上文，進(jìn)一步說明開車時(shí)脫水對(duì)駕駛失誤的影響。故G選項(xiàng)“但當(dāng)他們?nèi)彼畷r(shí)，駕駛失誤增加了一倍多，達(dá)到101次”符合上下文語境，故選G。

【5】根據(jù)上文The exact treatment for dehydration symptoms depends on age and how severely dehydrated someone is.可知，脫水癥狀的確切治療取決于年齡和某人脫水的嚴(yán)重程度。由此可知，本句承接上文說明不同程度，人們的應(yīng)對(duì)方法。故D選項(xiàng)“在極端情況下，人們可能會(huì)去醫(yī)院接受治療”符合上下文語境，故選D。
