You might make a disgusted face when you notice that the person waiting in their car at the red light next to you is picking their nose,but admit it,you do it too.And while it might be the natural option when there isn't a box of tissues around,it can be bad for you.The main reasons people feel the need to pick their nose is to clear it of dried liquid,stop an itch(痒),or just because it feels good.Boogers(鼻屎)form when dried liquid and cilia,the tiny hairs that line the nostrils(鼻孔),trap the dust,dirt,and other things.When boogers build up in your nose,it can be uncomfortable,and sometimes just blowing into a tissue doesn't do the trick.

Otolaryngologist Erich P.Voigt,MD,told Business Insider that picking your nose can cause injuries and bleeding within your nostrils.That's not terribly damaging,but when the bacteria from your hands get into your body,it can cause a cold and flu.So doctors strongly suggest not picking the nose.

If dry winter air is causing the dirty liquid to harden in your nostrils,making you want to pick,consider damping the air at home,or taking a steam shower to soften things up in there.

Children,who are most famous for having a finger up their nose,sometimes don't realize how much injury they're causing,and sometimes it.can lead to nose bleeds.

So,next time you go to pick your nose,think about how many bacteria are on your hands and in your boogers, and maybe reach for a tissue instead.Even if you 're alone,and not waiting for the light to turn green,please,use a tissue.

Do you sometimes argue about what seems to you to be a simple fact? Do you argue whether it’s cold outdoors or whether the car in front of you is going faster than the speed limit (限速)?

If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who felt the elephant’s trunk (象鼻) said it was like a snake. The second who felt the elephant’s side said it was like a wall, while the third said it was like a spear( 矛 ) as he touched the animal’s tusk. The fourth, who took hold of the elephant’s tail insisted that it was like a rope. The fifth man said it looked liked a tree as he put his arms around one of the elephant’s legs. The last, who was tall and got hold of the elephant’s ears, said it was like a huge fan.

Each man’s idea of the animal came from his own experience. So if someone disagrees with you about a “simple fact”, it’s often because his experience in the matter is different from yours.

To see how hard it is for even one person to make up his mind about a “simple fact”, try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm water (温水)in the third. Now put your left hand in the hot water. Put your right hand in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it is hot.

1.The man who touched the elephant’s ears must be very_______.

A. heavy B. thin

C. tall D. strong

2.The underlined word “it” in the last line of the paragraph refers to _______.

A. your left hand B. your right hand

C. the water D. the bowl

3.What makes people think about simple facts differently?

A. People’s wrong ideas. B. People’s different experience.

C. Simple facts are different sometimes. D. People often disagree with each other.

4.It can be inferred from the passage that we should__________.

A. learn from the blind men B. not agree about simple facts

C. never think about simple facts D. never decide anything with one side

Reading is really a good way to improve ourselves. 1. If you don’t believe me, please consider these reasons to read more books.

1. You will optimize your brain power.

2. Unlike watching television, which requires no thought process, reading is an active learning experience that will keep your mind sharp(even in old age).

2.3.

If you’re looking for entertainment on a budget, you can’t beat books. Thanks to the popularity of electronic reading devices like the Kindle and re-selling websites like eBay, it’s never been easier to entertain yourself for hours at a time, for the low cost of a few dollars.

3. You will reduce stress and get into a good night’s sleep.

Exposing yourself to artificial light on your cellphone or TV reduces your body’s production of melatonin (褪黑激素), which can make it difficult to get a good night’s sleep. 4. Just replace that with a good book, which is a much better sleep-friendly alternative.

4. You will change your life.

I firmly believe that if it were not for books, I wouldn’t have achieved so much in my life; nor would I have the knowledge, imagination or creativity that I depend on as a writer, business owner, and coach.

Do you have the desire to read books now?5.

A. You will entertain yourself at any time.

B. You will entertain yourself at a low price.

C. The more books you read, the better your life will be.

D. This shouldn’t come as a shock, but studies suggest reading makes you smart.

E. I hope these reasons encourage you to unlock your potential with the power of reading.

F. You should know that it is wise to keep a book in your purse or car at all times.

G. You would be wise to cut off all electronics at least an hour before bed.
