1.指的是某个时间段内不能使用手机,后面的should not be using your phone指的不是time的状态,times是一个限定条件.如果是the time ___ you've wasted,这里可以用that,因为wasted是修饰time.
2.如果填when,这一句话就必须有前文,变成当we have trouble doing something的时候,it often happens.那么我就要问了,what often happens?这个句子的原意是"we have trouble doing something"这个事件often happens,所以要用that引导后面的从句.
