求翻译：在材质上，夏季使用的窗帘一般透光性要强，宜用轻薄通透的材质。绒布在欧式风格中有不错的表现，但夏天使用则嫌厚重，业主可以选择更换，或不拉绒布帘，只拉纱帘、遮光布。如果想达到更好的透气性，或是想要随时看到室外的绿色风景，不妨选择清雅的竹帘或现代感的百叶窗帘。是什么意思？

The materials, summer use curtains of light transmittance is stronger in General, material should be treated with light permeability. Rongbuk in European style with good performance, but using too heavy in the summer, owners can choose to replace or not napped fabric curtains, gauze curtains, shade cloth only. If you want to achieve a better gas permeability, or want to see outdoor green scenery at any time, may wish to select elegant bamboo curtain or modern Venetian blind.
