It is possible that the weather of the
world may be changing. Some scientists imagine that this could even mean the
beginning of another ice age. The effects of such a change in weather on human
population of the world would be frightening. Recent research suggests that the warming trend (倾向)of the past hundred years or so may be coming to an end. During the past ten years, scientists tell us that the temperature of the world has dropped a little. This would have effects on wind and rain in the weather picture. Scientists believe clouds may be an important factor (因素) in changing the amount of heat on the earth. Another possibility is that man’s agriculture and industry ways may affect the natural weather. |

We find that bright children are rarely
held back by mixed-ability teaching. On the contrary, both their knowledge and
experience are enriched. We feel that there are many disadvantages in streaming
(把……按能力分班) pupils. It does not take into account the fact that children develop
at different rates. It can have a bad effect on both the bright and the
not-so-bright child. After all, it can be quite discouraging to be at the bottom
of the top grade! Besides, it is rather unreal to grade people just according to their intellectual ability. This is only one aspect of their total personality. We are concerned to develop the abilities of all our pupils. To the full, not just their academic ability. We also value personal qualities and social skills, and we find that mixed-ability teaching contributes to all these aspects of learning.< A. critical B. questioning C. approving D. objective [单项选择]
