[单项选择]The collapse of the Earth’s magnetic field—which guards the planet and guides many of its creatures—appears to have started seriously about 150 years ago, the New York Times reported last week.
The field’s strength has decreased by 10 or 15 per cent so far and this has increased the debate over whether it signals a reversal of the planet’s lines of magnetic force.
During a reversal, the main field weakens, almost vanishes, and reappears with opposite polarity. The transition would take thousands of years. Once completed, compass needles that had pointed north would point south. A reversal could cause problems for both man and animals. Astronauts and satellites would have difficulties. Birds, fish and animals that rely on the magnetic field for navigation would find migration confusing. But experts said the effects would not be a big disaster, despite claims of doom and vague evidence of links between past field reversals and species extinctions.
Although a total transiti
A. begun to change in the opposite direction
B. been weakening in strength for a long time
C. caused the changes on the polarities
D. misguided many a man and animal

Therefore, the great influence of parents cannot be ignored or discounted by the teacher. They can become strong allies of the school personnel or they can consciously or unconsciously hinder and thwart curricular objectives.
Administrators have been aware of the need to keep parents apprised of the newer methods used in schools. Many principals have conducted workshops explaining such matters as the reading readiness program, manuscript writing, and developmental mathematics.
Moreover, the classroom teacher, with the permission of the supervisors, can also play an important role in enlightening parents. The many interviews carried on during the year as well as new ways of reporting pupils’ progress, can significantly aid in achieving a harmonious interplay between school and home.
To illustrate, suppose that a father has been dr
A. is satisfied with present relationships between home and school
B. feels that the traditional program in mathematics is slightly superior to the developmental program
C. believes that schools are lacking in guidance personnel
D. feels that parent-teacher interviews can be made much more constructive than they are at present
