参考答案

正确答案：as well leave out the things you aren't sure of
as well leave out the things you aren't sure of 解析：as well与may/might/could连用，表示“还是……好了”，也可表示为may/might/could just as well，例如：There is nothing to do，so I may as well go to bed．没什么事可做，我还是上床睡觉好了。The taxi was so slow we might just as well have gone on the bus．出租车太慢了，我们还是乘公交车出去吧。
