since可不可以用在现在完成时中，还是只能用在现在完成进行时中？ 求教，since是不是只能跟现在完成时用，不能跟现在完成进行...

since可以用在现在完成时和一般现在时、过去完成时、一般过去时等中当since 解释为“自从”时，用于现在完成时，通常后跟时间，ago 以及一般过去式的句子。例句；China has taken place great changes since 1978. They have gone to Hong Kong since two days ago. It is(has been) twenty years since they moved here.
since 还有另一层意思“既然，由于”，时态视具体情况而定。
可以用在现在完成时中
