高三英语Unit2 Crossing limits 教学设计及教案

Sb: I think we should not use robots to take the place of human beings because space travel explores human’s possibilities. Space travel tests people’s courage, endeavor and ability. If we use robots we will become too dependent on them and lose courage in space exploration. Take Apollo’s landing on the Moon as an example, if it were not Armstrong and his co-workers, we would not know what the moon is really like.

Sample
Does the Use of Equipment Spoil or
Lower the Value of Human Achievement
With the advancement of social development, technology has become more and more important in every field of society. In science exploration, the use of all kinds of equipment has become so widespread that it causes heated discussion among people. Some experts argue that the wide use of equipment lowers people’s achievement in exploration. They believe that technology will take away the fun of risk in exploration. It is the fun which lies in exploration that continuously stimulates people’s curiosity about it. And the curiosity always impels the advancement of science development. Besides, in the course of exploration, there will be the unknown and challenges. All these that lie ahead test human’s courage and endeavor. If science exploration is too dependent on equipment, people will lose the pleasure of showing their courage and endeavor in exploration. Therefore, the use of equipment minimize people’s ability and makes people fell unable in face of the advanced equipment. And all the advancement achieved seems to be from the equipment, not by the effort of human beings.
On the other hand, some experts argue that, instead of lower human’s achievement, the use of equipment makes human achieve greater progress. With advanced equipment, many dangerous jobs will become safe and possible. What’s more, some equipment can make many kinds of work easier and faster. Owning to oxygen, the climbers made it possible to reach the summit of Qomolangma. Taking all these reasons into consideration, we can not walk faster in the field science exploration without the use of advanced equipment.
In my opinion, we live in a world with technology all around us. We can not avoid its influence in science exploration. Therefore, it is important to make proper use of equipment. In a word, all that can be done by human beings should be accomplished by human while all that are too dangerous and impossible should be fulfilled with the assist of equipment.
