The first day of school a new classmate touched my shoulder, “Hi, handsome﹗I’m Rose. I am 87 years old. Can I give you a hug? I turned around and found a little lady with a warm smile. I said heartily:” Of course﹗”
“Why are you in college at such an age?” I asked.
She joked, “I’m here to meet a rich husband, get married, have children, and then travel around.”
“No seriously,” I asked.
“I always dreamed of having a college education and now I’ getting one!” she told me.
Over the year, Rose became an icon(偶像) and she easily made friends. She loved to dress up and she enjoyed the attention of the others. At the end of the term we invited Rose to our football party. I’ll never forget what she said.
“We do not stop playing because we are old; we grow old because we stop playing. Here are the secrets to stay young. You have to laugh and find humor every day. You’ve got to have a dream. When you lose your dreams, you die! There's a huge difference between growing old and growing up. Anybody can grow older. That doesn't take any talent or ability. But growing up requires finding the opportunity in change. Have no regrets.”
One week after graduation that year, Rose died peacefully in her sleep. She taught us by example that it's never too late to be all you can possibly be.

Many of us have feelings of loneliness as we grow up. As a teenager, just eating alone in the dining hall can’t be acceptable, and girls even go to the restrooms hand in hand. They fear being called a “loner”.
In these cases, we might use the word “loner” in a disapproving (不赞成的) way. However, it can actually have a positive meaning as well.
It all depends on our attitude toward being alone. If we see being alone as something not very good, we will be against it. But if we understand that it’s an everyday part of life, we’ll be able to “hug the beauty of our solo (单独的) journey”, as best-selling US writer Mandy Hale wrote in her book The Single Woman.
In some countries, more young people are choosing to be loners. In South Korea, “honjok” has become a growing lifestyle. The word comes from Korean “hon” (alone) and “jok” (group).These people eat alone, travel alone, and enjoy being by themselves. “I hope it grows into a self-supporting culture of happiness.” said Jang Jae Young, a South Korean who runs a website about this solo lifestyle called www.honjok.me.
In Japan, people have developed a strong “loner culture” and even a “loner economy (经济).” There are many solo KTVs and solo coffee bars. Noodle restaurants for solo customers are especially popular. There are boards which separate each seat. Customers fill out a form to make an order, and then press a button to call the waiter. They don’t see the faces of other customers or waiters.
People are becoming more experienced in and comfortable about being alone. This doesn’t mean we should totally keep ourselves away from the outside world, of course. But it doesn’t hurt to have some “me time” once in a while.
1.From the passage we know that “honjok” ________.
A.means a group of loners B.is a culture which brings people closer
C.is a website run by a Korean D.will be a popular lifestyle in North Korea
2.The underlined word “separate” in Para. 5 means “________”.
A.合并 B.隔开 C.监控 D.固定
3.If we put the passage into three parts, which of the following is the best?
(①=Para.1 ②=Para.2 ③=Para.3 ④=Para. 4 ⑤=Para.5 ⑥=Para.6)
A.①; ②③; ④⑤⑥ B.①; ②③④; ⑤⑥
C.①②; ③④⑤; ⑥ D.①②③; ④⑤; ⑥
4.The best title of this passage is ________.
A.Ways to Deal with Aloneness B.A Tradition of Aloneness in Asian Countries
C.Aloneness—A Common Lifestyle D.Advantages and Disadvantages of Aloneness
