I remembered that when I was a little child, I used to look for Sunday of the week. Yes, I was so looking forward to an adventure.

Now, I still have a strong affinity for buses. I used to wonder where those gigantic (巨大的) buses finally stopped. On sunshine Sundays, that’s my adventure times. He took me to the bus stop. Time passed, while I was growing impatient, he was smiling, as he always does.

It was really not that easy to get on a bus as often as we do today. I was so worried that the bus driver would have missed us. I waved my hands so high with all my strength. I looked hopefully at him. He didn’t move at all. He was still standing. It seemed that the late and infrequent coming of the bus wasn’t any trouble to him at all.

He took my hand. We managed to find seats on the upper deck. I was so excited. Only sitting beside the windows made me happy. Looking at the rewinding buildings, streets and people through windows from a higher ground was so much fun. Then, he was sitting peacefully by me and whispered to me where the bus finally would stop. I was curious about what would be the next stop of our destination as much as what really means something to him.[]

That is me. I know now. I am all he cares. He wants me to be happy, as he always does. That’s the strong bond between father and son. Childhood, naive(天真)  and precious, you showed me the world and the way I look at the world. I am so grateful for your presence in my life. Thanks, you are so wonderful!

     Grown-ups are often surprised by how well they remember something they learned as children but

have never practiced ever since. A man who has not had a chance to go swimming for years can still

swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still

ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the

words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or remember

the story of Cinderella or Goldilocks and the Three Bears.

     One explanation is the law of overlearning , which can be stated as follows: Once we have learned

something, additional learning trials (尝试) increase the length of time we will remember it.

     In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing

baseball long after we have learned them. We continue to listen to and remind ourselves of words such

as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn

but overlearn.

     The multiplication tables (乘法口诀表) are an exception to the general rule that we forget rather

quickly the things that we learn in school, because they are another of the things we overlearn in

childhood.

     The law of overlearning explains why cramming (突击学习) for an examination, though it may result

in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn

the subject well enough to get by on the examination, but he is likely soon to forget almost everything he

learned. A little overlearning, on the other hand, is really necessary for one's future development.

1. What is the main idea of paragraph I?

A. People remember well what they learned in childhood.

B. Children have a better memory than grown-ups.

C. Poem reading is a good way to learn words.

D. Stories for children arc easy to remember.

2. The author explains the law of overlearning by_________.

A. presenting research findings

C. making a comparison

D. using examples

3. According to the author, being able to use multiplication tables is_______.

A. a result of overlearning

B. a special case of cramming

C. a skill to deal with math problems

D. a basic step towards advanced studies

4. What does the word "they" in Paragraph 4 refer to?

A. Commonly accepted rules.

B. The multiplication tables.

C. Things easily forgotten.

D. School subjects.

5. What is the author's opinion on cramming?

A. It leads to failure in college exams.

B. It's helpful only in a limited way.

C. It's possible to result in poor memory.

D. It increases students' learning interest.
