A high school history teacher once told us, ¡°If you make one close friend in school, you will be most fortunate. A true friend is someone who stays with you for life.¡±  1   teaches that he was right. Good friendship is just not easily    2   .

It is possible that we simply do not stay in one place long enough for a   3   friendship to develop. However, there can be no disagreement on the   4   for each of us to think carefully about the   5   of friendship we want.

To most of us, friendships are   6   very important, but we need to have cleared in our  7 the kinds of friendship we want. Are they to be close or   8  at arm¡¯s length? Do we want to share ourselves or do we want to walk on the   9   ? For some people, many friendships on the surface are   10   enough and that¡¯s all right. But at some point,  11   to make sure that our expectations are the same as our friends¡¯ expectations. The   12   of personal experience including our tears as well as our dark dreams is the   13    way to deepen friendships. But it must be undertaken(½øÐÐ)slowly and   14    only if there are signs of interest and action in return.

What are some of the   15   of friendship? The greatest is the attraction to expect too much time. Another ¡°   16    difficulty¡±is the selfishness to take actions too soon. Deep relationships   17   one ¡°possesses¡±the other, including his time and attention.  18   , friendships in return. In other words, you must give as much as you take.  19    there is a question of taking care of them.  20   you spend reasonable time together, talking on the phone, writing letters, doing things together, friendships will die away.

Love in a Box

When I was a little girl£¬I found love in a box all because of a class assignment.On a Friday night I__1__at the dinner table£¬¡°My teacher said we have to bring a box£¬a special box£¬for our Valentines (ÇéÈ˽Ú) on Monday.¡±

Mother said£¬¡°We¡¯ll see¡±£¬and she continued eating.

What did ¡°We¡¯ll see¡± mean£¿I had to have that box__2__my second grade Valentine¡¯s Day would be a disaster.Maybe they didn¡¯t love me enough to help me with my__3__.

All Saturday I waited__4__and with Sunday arriving£¬my concern increased£¬but I__5__an enquiry about the box might__6__anger or loud voice£¬for in my house children only ask once.More than that __7__trouble.

Late Sunday afternoon£¬my father called me into the kitchen.The table was covered with colorful__8__of different kinds.A(n)__9__shoebox rested on top of it.__10__flooded through me when Daddy said£¬¡°Let¡¯s get started__11__your project.¡±

In the next hour my father__12__the shoebox into an impressive valentine box.Colorful paper covered the ugly cardboard with red hearts__13__to what I considered all the right places.He sang while he worked.When he finished£¬he was so delighted that a__14__smile spread over his face.¡°What do you think of that£¿¡± he asked.

I answered him with a hug.

But inside£¬__15__danced all the way to my heart.It was the first time that my father devoted so much__16__to me£¬for his world consisted of work only.

The holiday party arrived£¬and my classmates put cards£¬and presents into the valentine boxes.Laughter filled our classroom until dismissal time__17__.

On the way home£¬I held out my valentine box for the world to__18__.The love that filled it meant more to me than all inside.

The valentine box became a symbol of his love that__19__through decades of other Valentine¡¯s Days.He gave me other gifts through the years£¬but none__20__compared with the love I felt within the limits of the old£¬empty shoebox.

It is natural that children are curious (ºÃÆæµÄ) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.

¡¡¡¡As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (ÉúÑÄ¡¢Ö°Òµ) in science.

¡¡¡¡Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .

¡¡¡¡These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (±Ã) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.

¡¡¡¡Of course, scientists cannot answer all of our questions. If we ask, ¡°Why does the ocean water taste salty¡± scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , ¡°What happens to the salt in the ocean? The ocean does not get saltier every year.¡± Scientists are not sure about the answer to this question.

¡¡¡¡We know a lot about our world, but there are still many answers that we do not have, and we are curious.

According to the passage, which of the following statements is true?

¡¡ A£®People are curious in the same way.

¡¡ B£®People in different countries are interested in different things.

¡¡ C£®Men and women are curious about different things.

¡¡ D£®People of different ages are interested in different things

Scientists who work with the biological sciences study____.

    A£®the earth , the oceans and the sky   B£®man-made things

A£®more nutrition and oxygen    B£®more signals   

C£®more salt                  D£®water

A£®in wet regions       B£®in dry regions

C£®at very high or very low temperatures     D£®when salty water falls in
