Coming home from school that dark winter day so long ago, I was filled with excitement of having the weekend off. But I was   1   into stillness by what I saw. Mother, seated at the far end of the sofa,   2  , with the second-hand green typewriter on the table. She told me that she couldn’t type fast and then she was out of work. My shock and embarrassment（尷尬）at finding Mother in tears was a perfect proof of how   3   I understood the pressures on her. Sitting beside her on the sofa, I began very   4   to understand. “I guess we all have to   5   sometime, ”Mother said quietly. I could   6   her pain and the tension（壓力）of   7   the strong feelings that were interrupted by my arrival. Suddenly, something inside me   8  . I reached out and put my arms around her. She broke then. She put her face   9   my shoulder and sobbed. I held her   10   and didn’t try to talk. I knew I was doing what I should, what I could   11   it was enough. In that moment, feeling Mother’s   12   with feelings, I understood for the first time her being so easy to   13  . She was still my mother,   14   she was something   15  : a person like me, capable of fear and   16   and failure. I could feel her pain as she must have felt mine on a thousand occasions（場合）when I sought   17   in her arms.

    A week later Mother took a job selling dry goods at half the salary the radio station   18  . “It’s a job I can do, though”she said simply. But the evening practice on the old green typewriter continued. I had a very   19   feeling now when I passed her door at night and heard her tapping   20   across the paper. I knew there was something more going on in there than a woman learning to type.

Some personal characteristics play an important role in the development of one’s intelligence . But people fail to realize the importance of training these factors in young people .

The so-called ‘non-intelligence factors’（非智力因素）include    1     feelings , will , motivation （動機）, interests and habits . After a 30-year follow-up study of 8000 males , American psychologists （心理學）   2     that the main cause of disparities in intelligence is not intelligence     3    , but non-intelligence factors including the desire to learn , will power and self-confidence .

    4    people all know that one should have definite objectives , a strong will and good learning habits , quite a number of teachers and parents don’t pay much attention to     5    these factors .

Some parents are greatly worried    6     their children fail to do well in their studies . They blame either genetic （遺傳的）factors , malnutrition ,（營養不良）or laziness , but they never take     7    consideration these non-intelligence factors . At the same time , some teachers don’t inquire into these , as reasons    8     students do poorly . They simply give them more courses and exercises , or     9    criticize or laugh at them . After all , these students lose self-confidence . Some of them just feel defeated and     10    themselves up as hopeless . Others may go astray（迷途）because they are sick of learning .   11     investigation of more than 1,000 middle school students in Shanghai showed that 11.5 per cent of them were   12      of learning , because of examinations , 1.4 per cent lacked persistence , initiative （主動）and consciousness （正直地、謹慎的）and 10.3 per cent were sick of learning .

It is clear    13     the lack of cultivation （培養） of non-intelligence factors has been a main     14    to intelligence development in teenagers . It even causes an imbalance between physiological （生理的）and    15     development among a few students .

If we don’t start now to   16      the cultivation of non-intelligence factors , it will not only affect the development of the   17      of teenagers , but also affect the quality of a whole generation . Some experts have put forward    18     about how to cultivate students’ non-intelligence factors .

First , parents and teachers should    19     understand teenage psychology . On this basis , they can help them to pursue （調動）the objectives of learning ,     20   their interests and toughening their willpower .

We’ve heard it before-we’ve heard it on the news, from teachers, from parents －children and teenagers today are growing up too fast. There are not too many people that will   1   with that statement. Teenagers are faced with serious problems and decisions at an early   2  . In fact most teenagers’ daily schedules（日程表）are as   3   as those of an adult’s.

    I have been working since I was thirteen, and always in   4   in which I was working with adults （成年人）. I have had to learn to think and   5   like an adult to be taken seriously. So, I count myself as one who has grown up too fast. I just graduated from high school, and have recently spent some time reflecting（反思）on the   6   eighteen years－thinking about myself, what I have gained, and what   7   I have yet to achieve.

    We are expected to work hard, get excellent   8  , be in a good relationship, and know what we want to do   9  . The list goes on and on. But the   10   is clear: We live in a society today that is   11   our childhood. We no longer have many years to be careless and fancy－free. We are expected to   12   the strict school rules and to excel （擅長）in everything we do.

    I’ve known these things for a long time, and knew that they   13   me. But, I never really admitted it until last night, when I learned a   14   lesson, taught to me by my boss where I work. We had finished a job at a remote（遙遠的）site. It was about 11:30 at night, and we had   15   to his house. We were talking about the   16   he had been making to his home. One of the things he said was “I   17   my basketball hoop（籃圈）. ”Then he threw a basketball to me.

    I hadn’t   18   a basketball in five years.

    We proceeded to shoot hoops for about 5 minutes. Both of us were terribly bad at it, but we spent the whole time   19   like children. Then I realized something: I am still a child. Oh, the law says I’m an adult. But, we are still really and truly children. We all need to have   20   once in a while.

Anthropology is a science which deals with man and his social habits. I think of anthropology here as “being interested, without 1, in the way other people choose to live and 2.”

―When you are curious about the way someone behaves or the way　3　feel about something, it’s　4　that you will he annoyed（惱火）.

When someone acts in a way that seems 5 to you, rather than react in your usual way, such as “I can't believe they would do that,” 6 say something to yourself like “I see, that must be the way they 7 things in their world. Very interesting.” In order for this 8 to help you, you have to be genuine (真誠的).

Recently I was at a shopping mall with my six-year old daughter　9　a group of punk rockers walked by with orange spiked hair and tattoos (紋身) covering much of their bodies. At the sight of them, my daughter immediately asked me, “Daddy, why are they 10 like that?” Years ago I would have felt very 11 with such young people. I would have given a judgmental explanation and passed along to her my 12. Pretending to be an anthropolgist, however, has 13 my perspective (看法) a great deal, so it’s made me 14 .I said to my daughter, “I’m not really sure, but it’s interesting how 15 we all are, isn’t it?” She said, “Yeah, 16 I like my own hair.”

When you are interested in other perspectives, it doesn’t mean you’re 17　them. I certainly wouldn’t choose a punk rock lifestyle or 18 it to anyone else. At the same time, however, it’s really not my 19 to judge it either. One of the most important rules of joyful living is that judging others takes a great deal of energy and 20 you away from where you want to be．

What is your favorite    1  ?Do you like yellow, orange or red? If you do, you must be an optimist（樂觀者）, a leader, an active person who enjoys life, people and  2  . Do you prefer grays and blues? Then you are   3  quiet, shy, and you’d rather  4  than lead. You tend to be a pessimist（悲觀主義者）.

After graduation from Harvard Medical School, Dr. William Thomas never thought he’d work in a nursing home. Then,  1   , he became a medical director of a nursing home in New York, and his ideas began to  2   . “For the first time in my career, I was  3   for the answer to the question, What does it mean to   4   another person?”

  5   that the biggest trouble facing nursing-home residents（居住者） are helplessness,

  6   and boredom, he arranged laughter, usefulness and love as  7   .

8   Thomas calls it, he began the “”Edenization” of the nursing home in 1992. At last he founded the Eden Alternative.

Lazy moments and loud television programmes were  9   with lovely children, playful pets,  10   plants and music in the lobby. These living things are  11   into life. Residents are

  12   to tend the animals, water the plants, weed outdoor gardens and do crarts with the children.

The Eden Altemative changed the   13   of the residents at this 80-bed nursing home. In a three-day study, the nursing home was  14   with a nursing home of equal size. The Eden Alternative had 26 percent less nurse-aide turnover, 15 percent   15   resident deaths and 3 percent lower medication costs.

In 1995 Dr. Thomas  16   his full time to the promotion of the Eden Alternative. More than 200 nursing homes throughout the country have  17   the Edenization process. Thomas receives queries（質疑）from as   18   away as Turkey, Japan, Brazil and the Netherlands. He hopes that his idea of filling “  19   ”into nursing homes and inviting the community in will help to “break conventional practice in long term   20   .”

 “Down-to-earth” means someone or something that is honest, practical and easy to deal with. It is   1   to find someone who is down-to-earth. A person who is down-to-earth is easy to talk to and   2   other people as equals. A down-to-earth person is just the   3   of someone who acts important and proud.

Down-to-earth persons   4   be important members of society, of course.   5  they do not let their importance “go to their heads”. They do not   6   themselves to be better persons than others of less importance. Someone who is filled with his own importance and pride, often without cause, is   7   to have “his nose in the air”. There is   8   way a person with his nose in the air can be down-to-earth.
