【題目】 Why Ultra-pure(超高純的)Water Is Actually Bad for Your Health Many people are surprised to hear that drinking purified water on a regular, daily basis is actually dangerous. So why is 100% ultra-pure water not good for us? 1

There is no such thing as truly pure water in the natural world. 2When these minerals dissolve(溶解)in water, they form what we commonly refer to as electrolytes(電解質).They allow us to perform all the “bioelectrical” functions such as moving, heart-beating, thinking, and seeing.

But pure water fails to provide these fundamental electrolytes. 3You can think of it this wayimagine a room with no gravity, split in half down the middle. You throw a couple hundred balls into the left side of the room. 4 But if you cut a bunch of holes in the barrier, they will slowly start to spread over to the right side. Eventually, they will be evenly distributed across the entire room.

The water in your organs stays at very specific levels of minerals. When you drink ultra-purified water, it pulls the minerals out of your blood just like the right side of the space room pulled some of the bouncy balls over from the left. 5

Purified water can only be recommended as a way of drawing poisons out of the body. Once this is accomplished, the continued drinking of purified water is a bad idea.

A.Purified water is an active absorber.

B.Since there's no gravity, they bounce around everywhere.

C.It actually tries to rob your body of them when you drink it.

D.Even water in the purest lakes contains small amounts of minerals.

E.If you drank enough of it, the lack of minerals would eventually kill you.

F.The simple answer is that ultra-pure water doesn't provide the natural minerals we need#

G.This is why materials tend to move from more concentrated areas to less concentrated ones.

【解析】

本文是一篇說明文,介紹了為什么喝超純水會對身體造成危害。

1空前“So why is 100% ultra-pure water not good for us?”提到了一個問題——為什么超純水對我們沒有好處?此處是對這個問題的回答,故F項(簡單的答案是,超純水不能提供我們需要的天然礦物質)符合語境。

2根據空前的“There is no such thing as truly pure water in the natural world.”可知,自然界中沒有真正純凈的水,此處是對前面的補充說明,故D項(即使在最純凈的湖泊里,水也含有少量的礦物質)符合語境。

3根據空前的“But pure water fails to provide these fundamental electrolytes.”可知,高純水不能提供這些基本的電解質,此處承接上文,講的是高純水對體內電解質的危害,故C項(當你喝高純水的時候,實際上它會把你體內的電解質奪走)符合語境。

4根據空前的“imagine a room with no gravity, split in half down the middle. You throw a couple hundred balls into the left side of the room.”可知,想象一個沒有重力的房間,從中間一分為二,你把幾百個球扔到房間的左邊,此處承接上文,講的是沒有重力的影響,故B項(因為沒有重力,它們到處彈跳)符合語境。

5根據空前的“When you drink ultra-purified water, it pulls the minerals out of your blood”可知,當你喝超純水時,它會把你血液中的礦物質排出體外,此處總結上文,說的是缺乏礦物質對身體的不利影響,故E項(如果你喝的足夠多,礦物質的缺乏最終會殺死你)符合語境。

Last weekend, I went to visit my English teacher, who was already in his fifty. He gives me a lot of help when I was a junior middle school student. Delighting to see me, he asked my senior middle school life. Then he advised me to make fully preparations for the coming entrance examination. It was so a pleasure to see him again that I didn’t notice it was pretty later. I had to say goodbye to each other.

He is not only a good teacher but my close friend. Wherever I will go, I will always treasure a time that I spent with my teacher.
