Usages of jiāotōng
我 奶奶 说， 她 年轻 的 时候 交通 不 发达， 去 一 次 市中心 或许 要 一 天。wǒ nǎinai shuō, tā niánqīng de shíhou jiāotōng bù fādá, qù yí cì shìzhōngxīn huòxǔ yào yì tiān.
My grandma says that when she was young, transportation wasn’t developed, and going downtown once might take a whole day.
现在 交通 很 发达， 从 郊区 到 市中心 的 地铁 常常 很 满， 要 坐 四十 分钟， 比 公交车 方便。xiànzài jiāotōng hěn fādá, cóng jiāoqū dào shìzhōngxīn de dìtiě chángcháng hěn mǎn, yào zuò sìshí fēnzhōng, bǐ gōngjiāochē fāngbiàn.
Transportation is very developed now; the subway from the suburbs to downtown is often very full and takes forty minutes, but it’s more convenient than the bus.
