in和within的用法区别
in后接表示时间长度的名词，意为“过多少时间”或“在多少时间内”，有“不少于”之含意；within后可接表示时间长度或距离的名词，表示在“这一范围内”，有“不到”或“不超过”之意。如：

过几天学生将要期中考试。
②He will be hack in a week. 他过一星期回来。
③ He finished drawing the horse in/within five minutes.
他五分钟内画完了那匹马。

⑤Keep the dictionary within your reach.
把词典放在你够得着的地方。(不用in)
▲in表示“过多少时间”时，通常和一般将来时连用，如句①②：表示某一动作“在多少时间内”完成时通常用within，和一般将来时，一般现在时或一般过去时连用。
▲句①中 in a few days\'time = in a few days. 如要说某一活动或事情离现在还有多少时间，一般说 in…time或 away。如：
⑥ Bob\'s birthday is in five days\' time.＝Bob\'s birthday is five days away.
