Do you drink water that's been left sitting out overnight or even for another day? Have you noticed it tastes different?

Tap water that has been left to sit out slowly begins to acquire(獲得) off taste. Many people think that this is because of microorganisms. But that's not what makes old water taste not fresh. For that we can thank carbon dioxide. After about 12 hours, tap water starts to go flat as carbon dioxide in the air starts to mix with the water in the glass, lowering its pH and giving it an off taste. But it's most likely safe to drink.

However, back to those microorganisms. If you use a dirty glass day after day, there is more of a chance of bacteria making themselves known; a risk that increases if you share the glass with another mouth as well. But assuming(假設(shè)) you use a fresh glass every few days, you probably won't have a problem unless the glass has been touched by dirty fingers, and especially if those dirty fingers went unwashed after using the bathroom.

As for plastic water bottles that have been left out in the sun or in the car, step away from the bottle, warns Dr. Kellogg Schwab, director of the Johns Hopkins University Water Institute. "A chemical called bisphenol-A, or BPA, along with other things used to make plastic can leach(過濾) into your water if the bottle heats up or sits in the sun," he explains. BPA, as you probably know, has been linked to everything from heart disease to cancer. Schwab also adds that plastic used for commercial bottled water isn't meant to be washed or refilled, so use only one time and recycle. Or don't buy them at all; use refillable water bottles instead.

1.Tap water begin to acquire an off taste because of______ .

A. BPA B. carbon dioxide

C. the glass D. the microorganism

2.According to Paragragh 2 , tap water that's been left sitting out for 12 hours____.

A. is still safe to drink B. tastes better

C. contains few microorganisms D. is most likely undrinkable

3.What should we do with plastic water bottles that have been left out in the sun or in the car?

A. Throw them away.

B. Clean them and use them again.

C. Use them after they cool down.

D. Refill them with fresh water.

4.Which of the following is true about BPA

A. It is safe for people to use.

B. It is a kind of new material.

C. It can cause great harm to people.

D. It is the main material to make plastic.

Robert Ballard is probably the most famous deep-sea explorer in the past 100 years. While he is best known for his historic discovery of the wreckage(殘骸) of the R.M.S. Titanic which sank to the bottom of the sea in 1912, he also discovered the wreckage of the Bismarck and the Yorktown. Over his career, Dr. Ballard has completed over 120 deep-sea journeys and continues to push exploration to new depths with new technologies and strategies. His new high-tech Inner Space Center at the University of Rhode Island links scientists all over the world and makes it possible to identify new discoveries in realtime.

During one of those expeditions, I met Dr. Robert Norris, a Scripps graduate with a Ph. D. in marine geology, who invited me to come to the University of California, Santa Barbara where I ended up getting my undergraduate degree in Geology and Chemistry with minors in Math and Physics.

I’ve just got to talk about this problem I’m having with my postman. It all began a year ago, after the birth of his first child. Not wanting to appear rude, I asked him about the baby. The next week, not wanting him to think I had asked out of mere politeness the week before, I asked all about the baby again. Now I can’t break the habit. I freeze whenever I see him coming. The words “How’s the baby?” come out on their own. It holds me up. It holds him up. So why can’t I stop it? The answer is that I want him to like me. Come to think of it, I want everyone to like me.

What about at work? Richard Lawton, a management trainer, warns: “Those managers who are actually liked by most of their staff (員工)are always those who are honest with staff, treating them as human beings and following common politeness like saying hello in the morning.” To explain the point, Richard told the story of the company chairman who especially wanted to be liked. One day, after making one of his employees fired, the employee replied: “If you were that sorry, I wouldn’t be leaving.” The lesson is that if you try too hard to be liked, people won’t like you.

The experts say it all starts in childhood. “If children feel they can only get love from their parents by being good,” says Zelda West-Meads, a marriage adviser, “they develop low self-confidence.” But is there anything wrong in being a giver? Anne Cousins believes there is. “Sometimes giving becomes unhealthy,” she says. “It comes when you do things for others but feel bad about it.”

I am now trying hard to say to people “I feel uncomfortable about saying this, but…” and tell myself “Refusal of a request does not mean Refusal of a person” and I find I can say almost anything to almost anyone.

1.Why does the author ask the postman about his baby?

A. He is interested in the baby.

B. He wants to be always polite to him.

C. He wants to leave a good impression to him.

D. It’s a way to start a chat with great politeness.

2.Managers are more likely to be popular if they ______.

A. help the staff with their problems

B. make sure the staff do not lose their jobs

C. encourage the staff to be polite to each other

D. do not make too much effort to be liked

3.What is the author’s intention of writing this passage?

A. To show how to let others like you more.

B. To encourage people to have more self-confidence.

C. To prove how to create a harmonious atmosphere.

D. To suggest ways of dealing with difficult people.

He Jiang, who was the first person from China to deliver a Harvard University commencement (學(xué)位授予典禮) address, has made the 2017 Forbes 30 Under 30 List.

Forbes’ 30 Under 30 is a set of lists issued annually by Forbes magazine. On Tuesday, the magazine published the sixth annual 30 Under 30, featuring 600 young inventors and leaders who challenge conventional wisdom and rewrite the rules for the next generation.

The list recognizes 30 game-changers in each of 20 industries. All under 30 years old, the candidates were examined by a group of judges in their fields. “The winners are the people that will run every field for the next 50 years,” said Randall Lane, editor of Forbes.

He, a 29-year-old postdoctoral fellow at the Massachusetts Institute of Technology, was chosen for the healthcare category. He was recommended by his professors at Harvard.

At Harvard, He used a new technology to understand more about how flu infects cells, and discovered human genes with strong anti-viral effects. He is now applying the same techniques to white blood cells. He hopes the lab research he did could be put to practical use in healthcare.

He grew up in a small village with limited educational opportunities. By studying hard, he graduated from the University of Science and Technology of China with a bachelor’s degree in 2009, and was accepted into Harvard’s PhD program on a full scholarship the same year.

In May, the biochemistry PhD delivered a speech representing the university’s 13 graduate and professional schools at the ceremony. In the speech, he talked about the unbalanced distribution of science and medicine into places they aren’t reaching, like his own village, where his mother once treated his spider bite with fire.
