The incident took place, believe it or not, on the playground. I was something of a football player, but I had never been a good player, far less a great one. I played for the mere physical joy that I got out of the game, but I played with a will, and put my whole heart into the game. The result was that, though I had plenty of energy and enthusiasm, I was never picked for my college team.

Let me confess frankly that this was only because there was another player in the same position who happened to be much better than me. I considered myself the better sportsman, but he was certainly the greater player. So I never grumbled or complained. I was content to wait and bide my time.

And at last my patience was rewarded. It was for me a very special day. Our team had shot up into the final and was meeting its rival(竞争对手). Our star­player sent word at the last moment that he was ill and he could not take the field. Imagine the astonishment in the college camp! The thought was that the game was as good as lost, and so also, I confess, did I for this player was our trump card(王牌): That is what everybody always said. However, something had to be done, and that something had to be myself! The captain called me up almost apologetically for having failed to recognize my greatness before, and—there I was, on the playground, greeted by the cheers of my friends, and a few jeers from those who had little faith in my prowess.

I can tell you that I played like a demon(魔鬼). I was here, there and everywhere—now leading the attack, now falling back to help the defense. It was indeed a thrilling moment in my life. For a time, I was the center of all attention, the object of universal applause, and “the observed of all observers”. And, believe it or not, it was I who put in the winning goal. It marked the top of a glorious day. Even now I look back on the episode with unmixed pleasure and satisfaction.

There is increasing alarm about the extent of microplastic pollution, which has been found everywhere from Everest to the Arctic. However, it turns out there’s an even smaller and more toxic form of plastic pollution entering remote reaches of the globe. A new study published in Environmental Research found significant quantities of nanoplastics in ice samples from both the North and South Poles.

“Now we know that nanoplastics are transported to these corners of the Earth in these quantities. This indicates that nanoplastics are really a bigger pollution problem than we thought,” study lead author Dusan Materic said in a press release.

Nanoplastics are plastics that are smaller than a micrometer in size. Their small size means they are more difficult to study than microplastics, or plastics between five millimeters and a micrometer. But they may be even more dangerous.

“Nanoplastics are very toxicologically (毒理学地) active compared to, for instance, microplastics, and that’s why this is very important,” Materic said.

Materic and his team used new methods to measure nanoplastic pollution in ice samples from Greenland and Antarctica. They sampled a 14-meter-deep ice core from the Greenland ice cap and sea ice from Antarctica’s McMurdo Sound. They found that there were an average of 13.2 nanograms per milliliter of nanoplastics in the Greenland ice and an average of 52.3 nanograms per milliliter in the Antarctic ice.

But what was even more surprising than the amount of nanoplastics in the remote ice was just how long they had sat there. “In the Greenland core, we see nanoplastic pollution happening all the way from the 1960s. So organisms in that region, despite the lack of the solid evidence, likely all over the world, have been exposed to it for quite some time now,” Materic said.

The study also looked at the types of plastic present in the samples. Half of the Greenland nanoplastics were polyethylene (PE), the kind of plastic used for plastic bags and packaging. A quarter came from tires and a fifth were polyethylene terephthalate (PET), which is used for clothing and bottles.

“I’m sorry” are two very important words that play a big part in daily life. You might apologize while squeezing through a crowd or using the last of the printer paper at work. It’s easy to say “I’m sorry”, but true apologies are a different story.    13     Or you may wonder how to properly demand an apology if the other person is at fault? With the following tips, you’ll find these are not hard.

Apologize sincerely. A genuine apology can help repair your relationship, and even your reputation—you’re showing that you can be trusted to do what’s right. But your relationship will remain tense if your apology seems casual.    14    

Apply specific principles. A meaningful apology comes down to the three R’s- regret, responsibility and remedy (补救办法). Firstly, communicate your regret. Show the other person you have recognized your error and can relate to his/her pain. Then take complete responsibility.    15     Lastly, show that you’re working to improve the situation. Offer to make up for the harm you caused or promise you wouldn’t repeat it again.

    16    If you’re the offended (冒犯) party, describe what’s changed in the relationship and your true feeling. For example, you could say, “Although there’s a disagreement between you and me, I want us to be friends again. But I’ve been hurt, and I’d like an apology. I need you to acknowledge what you’ve done.”

Don’t expect immediate forgiveness. Most people hope for immediate forgiveness while apologizing, but that may mean you don’t respect the others’ emotions and all you care about is yourself.    17    After all, they were hurt and it would take them a while to recover.
