注：(1) for和since引导的时间状语的区别: for + 一段时间, since + 一点时间 从句(从句中常用一般过去时)
(2)表示继续的现在完成时也可和lately, recently, so far, up to now, till now, in the past(last) few years……, this week (month, year……), all day, all this week等时间状语连用。如：

1. 现在完成时和一般过去时的区别
(1)两者都可表示过去发生过的动作，但前者表示的是过去的动作对现在的影响，而后者则是表示过去动作的事实。
(2)两者都可表示过去开始并延续了一段时间的动作，现在完成时含义为该动作仍在继续，而一般过去时则说明该动作现已终止。如：

某些非延续性动词可以与since连用，表示重复的动作或状态。如：

有些非延续性动词现在完成时在否定结构中可以与since或for短语连用。如：
He has never touched beer for a whole week.
I haven't bought anything for a year.
3. has been to和has gone to的区别
has been to表示“曾经去过”说明所提及的对象一回到说话地点
has gone to表示“去……”说明所提及的对象不在说话地点。如：

Tom has gone to Beijing and will come back next week.汤姆已到北京去了，下星期才回来。
