托福综合写作范文:Sample answer:
In the lecture, the professor refutes against the view raised in the reading that space-based solar panels are better than earth-based solar panels.
Firstly, the reading holds that the space-based solar panels can capture more energy for without the blockage of the earth’s atmosphere they can absorb more sun energy. However, the professor refutes that they can not gather more energy in the long term. When they have some problem functioning, due to the fact that people should be sent to the space to fix them, the cost and the time is far from plausible. Therefore, the time when they can work well to absorb energy is not very long.
Secondly, the reading claims that they can be exempted from meteoroid impacts for they can more easily detect meteoroids. But the professor disagrees with this by suggesting that despite of little chance of meteoroid impacts, there are space dusts which can cause huge damage to them. The space dusts are such tiny particle that they can be hardly detected. What’s more, their speeds are so fast that they can cause intensive heat which will definitely impair the panels.
Finally, in the reading passage, it indicates that they are environment-friendly, posing no harm to the earth. In contrast, the professor holds that the space-based panels depend on beams to transmit the energy to the earth, which will damage the ozone layer. In such situation, ultraviolet rays will directly penetrate the atmosphere, harming the human and animals on the earth and also leading to the decrease of the crop production.
