这题太难了，我索性先做后面的简单题。

Zhè tí tài nán le, wǒ suǒxìng xiān zuò hòumiàn de jiǎndān tí.

This question is too hard, so I might as well do the easier ones later in the test first.

既然票已经卖完了，我们索性改天再来吧。

Jìrán piào yǐjīng màiwán le, wǒmen suǒxìng gǎitiān zài lái ba.

Since the tickets are already sold out, we might as well come another day.

反正今天也睡不着，我索性把这本书看完。

Fǎnzhèng jīntiān yě shuìbuzháo, wǒ suǒxìng bǎ zhè běn shū kànwán.

Since I can't fall asleep anyway, I might as well finish reading this book.
