现在完成时讲解与专项练习
The present perfect tense is used to describe an n or state that began in the past and continues up to the present or has just ended。

It is formed by using the auxiliary verb "have/has" followed by the past participle of the main verb.
For example。

"He has turned off the light" means that the n
of turning off the light happened in the past。

but the result of the n (the light being off) is still relevant to the present.
Another use of the present perfect tense is to XXX up to the present or may continue in the future。

This is often used with continuous verbs and is XXX such as "for" or "since".
For example。

"Mary has been ill for three days" means that Mary became ill three days ago and is still ill now.
It is important to note that the present perfect tense cannot be used with specific XXX such as "for" or "since"。

It is often used
with time XXX general or indefinite。

such as "already"。

"yet"。

"just"。

"before"。

"recently"。

"still"。

and "lately".
Finally。

the present perfect tense is often used with time
XXX indicate frequency。

such as "ever"。

"never"。

"twice"。

and "several times".
Have you ever been to Beijing。

I have XXX。

I have only used this pen three times。

but it is still in good n。

e has had the XXX。

"She has been up for quite some time" instead of "She has got up for quite some time"。
