Dear Tim,There are many ways ① to go to Ningxia Library. One way is ② to go there by bus. But you need ③ to change a bus and walk for a while when you get off the bus. Another way is④ to take a taxi, but it'll cost you more money and time because it is difficult ⑤ to get a taxi at weekends. I think it' s easier and quicker ⑥ to go there by bike. What’s more, it is good for your health.Best regards, Li Ming
