3.表达 从表达方面来看，发言者的语言流利度和语速基本一致，仅有少数停顿。但在某些地方，发言者的表达略显生硬，可以尝试使用更自然的说法。此外，注意正确发音以避免拼写错误。建议多加练习，提高口语表达能力。

4.话题发展 The speaker provided a coherent and well-organized response, explaining two ways weathering occurs: ice formation and plant growth. However, the answer could be improved by using more specific examples and details from the lecture, such as mentioning how the expanding ice pushes outward on either side of the crack in the rock, or how tree roots extend downward into the cracks and crevices of the rock in search of water and nutrients. Additionally, try to use more varied sentence structures and transitions to make the response even more coherent and well-organized.

Original Answer: The two-way weathering occurrence refers to the process of the ice formation and tree growing. The weathering process occurs in two ways: through ice formation and plant growth. (原句表达不够自然，修改为更通顺的说法。) The first process is referred to the ice formation. The first method involves ice formation. (改进句子结构和词汇选择。) When some water gets into the crocks cracks (拼写错误，应为"cracks"。) in the daylight and when the temperature is dropping and the ice formation will widen the crocks cracks (拼写错误，应为"cracks"。) of the rocks over time and eventually make the rock has been split out. The second process refers to the growing of plants. The second method involves plant growth. (改进句子结构和词汇选择。) For instance, if a seed gets into the rocks and it grows to be a big tree and on the top of the rocks which gets its root deep inside the rocks and will split out the rocks eventually.

Revised Answer (140 words): The weathering process occurs in two ways: through ice formation and plant growth. The first method involves ice formation, which happens when water seeps into the cracks of rocks during the day. As temperatures drop at night, the water freezes and expands, causing the cracks to widen over time. This repeated process eventually leads to the rock breaking apart. The second method involves plant growth, specifically when a seed lands in a crack within a rock and begins to grow into a tree. As the tree matures, its roots extend deeper into the rock's crevices in search of water and nutrients. Over time, these expanding roots widen and enlarge the cracks, ultimately causing the rock to break apart. Both ice formation and plant growth contribute to the natural weathering process that breaks down rocks.
