[单项选择]
If it were only necessary to decide whether to teach elementary science to everyone on a mass basis or to find the gifted few and take them as far as they can go, our task would be fairly simple. The public school system, however, has no such choice, for the two jobs must be carried on at the same time. Because we depend so heavily upon science and technology for our progress, we must produce specialists in many fields. Because we live in a democratic nation, whose citizens make the policies for the nation, large numbers of us must be educated to understand, to support, and when necessary, to judge the work of experts. The public school must educate both producers and users of scientific services.
In education there should be a good balance among the branches of knowledge that contribute to effective thinking and wise judgement. Such balance is defeated by too much emphasis on any one field. This question of balance involves not only the relation of the natural sciences,

[简答题] Easter
Easter is the most important festival in the Christian calendar. It is the commemoration of Jesus’’ death and his rising from the dead, also known as the resurrection. It comes at the end of Lent. The week leading up to it is called Holy Week. Palm Sunday is the first day of Holy Week and celebrates Jesus’’ arrival in Jerusalem riding on a donkey. Crowds of people came out of the city to greet him, throwing down palm branches on the road.
