常见错误

❌ 错误:He is taking radiotherapy.
✓ 正确:He is undergoing radiotherapy.

错误:使用“taking”描述放射疗法不准确,因为放射疗法是一种医疗过程,不是口服药物。正确:应用“undergo”或“receive”来表示接受治疗。

❌ 错误:Radiotherapy can cure all cancers.
✓ 正确:Radiotherapy can help treat many cancers, but not all.

错误:夸大放射疗法的效果,暗示它能治愈所有癌症,这不准确。正确:应说明放射疗法是治疗许多癌症的有效方法,但并非适用于所有情况,需根据具体病情评估。
