【題目】根據(jù)短文內(nèi)容，選擇最佳答案。
The healthy adolescent boy or girl likes to do the real things in life,to do the things that matter. He would rather be a plumber's mate and do a real job that requires doing than learn about hydrostatics(流體靜力學(xué))sitting at a desk, without understanding what practical use they are going to be. A girl would rather look after the baby than learn about child care. Logically we should learn about things before doing them and that is probably why the experts enforce this in our educational system.But it is not the natural way---nor, in my view, the best way. The adolescent wants to do things first for only then does the appreciate the problems involved and want to learn more about them.
They do these things better in primitive life,for there at puberty(青春期) the boy joins his father in making canoes,patching huts,going out fishing or hunting.He is serving his apprenticeship in the actual accomplishments of life.It is not surprising that anthropologists(人類學(xué)家) find that the adolescents of primitive communities do not suffer from the same neurotic(神經(jīng)質(zhì)的) “difficulties” as those of civilized life.This is not,as some assume,because they are permitted more sexual freedom,but because they are given more natural outlets for their native interests and powers and are allowed to grow up freely into a full life of responsibility in the community.
In the 19th century this was recognized in the apprenticeship system,which allowed the boy to go out with the master carpenter,or ploughman,to engage in the actual work of carpentry or roof-mending,and so to learn his trade.In some agricultural colleges at the present time young men have to do a year's work on a farm before their theoretical training at college.The great advantage of this system is that it lets the apprentice see the practical problems before he sets to work learning how to solve them,and he can therefore take a more intelligent interest in his theoretical work.
Since more knowledge of more things is now required in order to cope with the adult world, the period of growing-up to independence takes much longer than it did in more primitive community,and the responsibility for such education,which formerly was in the hands of the parents,is now necessarily undertaken by experts at school. But that should not make us lose sight of the basic principle, namely the need and the desire of the adolescent to engage responsibly in the real pursuits of life and then to learn how—to learn through responsibility, not to learn before responsibility.
（1）According to the author, what is the natural way of education?
A.Doing things while learning.
B.Doing things before learning.
C.Doing things as an apprentice.
D.Learning practical knowledge first.
（2）The main advantage of the natural way of education, whether in primitive or modern times, is that learners.
A.can learn the trade through solving problems at work
B.can work with their masters throughout their learning
C.are given opportunities to develop their interest first
D.are given more freedom in doing things and learning
（3）According to context, “this” in the third paragraph refers to ________.
A.the kind of skills boys learned from their father
B.the difficulties modern adolescents experience
C.the amount of freedom in learning in primitive life
D.the way of learning in primitive communities
（4）Which of the following sums up the author's main point?
A.The apprenticeship system was effective in learning.
B.Learning to solve problems is learning through responsibility.
C.Students develop their interest through learning.
D.Students should be given more freedom in learning.

Yesterday we had our PE lesson. The teacher had taught us how to practice high jump. The bell rang and we went to the playground in line. The teacher told me the way of jumping and then gave us example. Followed the teacher one after another, my classmate did very well. Soon it was my turn and I felt little nervously. I failed at my first attempt, but I was not a bit discouraging. I kept on thinking about the teacher's words and practising. I managed to jump over the pole at the end. From this class I have realized one can succeed whether he was perseverance(毅力), just as an old saying go, “Where there is a will, there is a way.”
