实验室的帘子必须使用阻燃材料,以免设备短路时扩大火势。Shíyànshì de liánzi bìxū shǐyòng zǔrán cáiliào, yǐmiǎn shèbèi duǎnlù shí kuòdà huǒshì.The laboratory curtains must use flame-retardant material to avoid spreading a fire if equipment short-circuits.
早上我拉开帘子,阳光一下子照了进来。Zǎoshang wǒ lākāi liánzi, yángguāng yíxiàzi zhào le jìnlái.In the morning I pulled the curtain open and sunlight streamed in.
夜里风一吹,窗边的帘子就轻轻晃动起来。Yè lǐ fēng yì chuī, chuāng biān de liánzi jiù qīngqīng huàngdòng qǐlai.At night when the wind blew, the curtain by the window swayed gently.
