How do you say

It takes me about half an hour to ride my bike to work every day.

..in Chinese?

我每天骑自行车去上班需要大约半小时。

wǒ měi tiān qí zì xíng chē qù shàng bān xū yào dà yuē bàn xiǎo shí 。

How do you say "Beijing has enjoyed several weeks of sunny, warm days, though nights have been cooling off." in Chinese?
