We all know that water is tasteless. But it happens from time to time: you pick up the bottle of water you didn’t finish yesterday, and it tastes strange. Most often, you tend to drop the bottle in the trash bin, believing that the water has gone bad. But is it true?

According to Time, of course not, taste has little to do with quality of water.

According to Time, when water is exposed to the air for 12 hours, carbon dioxide interacts with the H2O in the water, and the pH value lowers slightly. As a result, the water has a different taste.

“But it’s most likely safe to drink,” Norwegian expert Truls Krogh told Science Nordic. “If the water is covered and of good quality to start with, in principle it can last a thousand years. That’s because when water is fresh, it contains little organic matter. As long as water is held in clean glasses or bottles, no pollutants will enter it to harm our health.”

People in countries like the US, the UK and Australia usually drink tap water. According to Time, if tap water is drunk within six months, the chlorine (氯气) in the water will be enough to kill any bacteria and keep it safe to drink.

However, there are also some exceptions. If you accidentally put your fingers into water or store water in unclean containers day after day, microorganism (微生物) will enter the water.

With the help of surrounding temperature, and sunlight streaming through windows, these microorganisms multiply quickly. Sooner or later, the water will be in the charge of the unfriendly bacteria. And if you drink the water too often, then you’re more likely to be ill.

And what about water in plastic bottles? Heat and plastic are a bad combination, US researcher Kellogg Schwab stresses. When plastic bottles are used at high temperatures, they produce a chemical called BPA. BPA is something that affects hormones (荷尔蒙) and research has tentatively linked it to “several health damage, including heart disease and cancer”, Time reported.

Schwab suggests replacing disposable (一次性的) plastic bottles with the refillable containers made of metal or glass to deal with BPA.

1.The purpose of the first paragraph is to ________________.

A. show an example B. draw a conclusion

C. analyze a phenomenon D. introduce a topic

2.Which of the following may Truls Krogh agree?

A. If the water tastes different, we shouldn’t drink it.

B. The water held in a clean container is likely safe to drink.

C. Although kept fresh, water may still have much organic matter.

D. Covered water can last for a thousand years.

3.What can we infer from the passage?

A. BPA does little harm to our health.

B. Tap water is always safe to drink.

C. Microorganisms are easy to produce in the heat.

D. Disposable plastic bottles have been banned already.

4.What can be the best title of the passage?

A. Why Water is Tasteless B. How to Get Clean Water

C. Does Water Really Go Bad? D. Learn to Protect Water

We all have our ways of marking time. As a photographer, my life is measured from one story to the next. My oldest son was born in the middle of a long story about the Endangered Species Act. My daughter came along with a pack of gray wolves.

Twenty stories later, though, it’s the story in Alaska that I’ll remember best. It was the story about the loss of wilderness — and the story during which my wife Kathy got cancer. That’s the one that made time stand still. I stopped taking pictures on the day when she found that tumor (肿瘤). Cruelly, it was Thanksgiving. By Christmas, she had become very weak. Some days she was so sick she couldn’t watch TV.

Early examination saves time. But ours was not early. By the time you can feel it yourself, it’s often bigger than the doctor want it to be.

Cancer is a thief. It steals time. Our days are already short with worry. Then comes this terrible disease, unfair as storm at harvest time. But cancer also has the power to change us, for good. We learn to simplify, enjoying what we have instead of feeling sorry for what we don’t. Cancer even made me a better father. My work had made me a stranger to my three kids. But now I pay attention to what really matters. This is not a race. This is a new way of life and new way of seeing, all from the cancer.

In the end each of us has so little time. We have less of it than we can possibly imagine. And even though it turns out that Kathy’s cancer has not spread, and her prognosis (诊断) is good, we try to make it all count now, enjoying every part of every day.

I’ve picked up my camera again. I watch the sky, searching for beautiful light. When winter storms come, Kathy and I gather our children and take the time to catch snowflakes (雪花) on our tongues. After all, this is good. This is what we’re living for.

1.As a photographer, the author used to ______

A. leave his daughter with a pack of gray wolves

B. devote much more to his career than his family

C. miss a great many important historical moments

2.Why did the author decide to stop taking pictures?

A. To cure his own disease.

B. To leave the wilderness alone.

D. To spend more time with his wife.

3.What is the biggest change the cancer has brought to the author?

A. He takes his work more seriously

B. He has become a stranger to his children.

C. He treasured every bit of time with his family

D. He focuses more on medical care.

4.The author and his family catch snowflakes on their tongues probably because ______.
