问题:

Compared to the other parts of the body, our ears don’t ask for much. They don't need to be brushed once a day like your teeth. But they need some special care, especially if you like listening to music with earphones.

Maybe your mum or dad has told you, "Turn that down before you go deaf!" Well, they are quite right. Loud noise might cause hearing loss for a short time or even forever. Think that earphones are a good way to escape from your parents’ eyes? Well. It may not be as good a way as you expect. American doctors have studied a group of 44,000 people who used earphones more than 15 hours per week. The doctors found that 37,000 of them were getting hearing problems.

If you use earphones for too long a time, your ears might feel painful. You could also lose your hearing for the rest of your life.

So don’t wear your earphones too long. Use them less than one hour a day.

Want sharp hearing? Don’t forget to do the following:

Try to stay away from places where there is too much noise, like a disco. If you have to go, wear earplugs.

When swimming, remember to put earplugs into your ears to stop water from getting in.

Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out.

Keep these things in mind! Then you won't be saying "WHAT???" when you are older.

货币,有着复杂的矛盾性,它似乎引力无穷,又似乎不值一取;有爱货币的古人,“夺泥燕口,削铁针头,鹭鸶脚上劈精肉,蚊子肚里刳脂油”;有爱货币的洋人,如为大家熟悉的葛朗台,阿尔巴贡等。但有另一些人,却对货币的种种诱惑视而不见。有“不为五斗米折腰”的,不去追名逐利,而去“采菊东蓠下”;有“一肩明月,两袖清风”的,不爱货币,因为“难得糊涂”。

(1)在“引力无穷”和“不值一取”之间我们应该采信哪种观点?为什么?

(2)我们应当怎样认识和对待货币?
