I have never been there before,…
Have you found him yet
Have you ever been to France
Yes, I have seen him already.
现在完成时常与下列副词连用：already(多用于肯定陈述句），never (多用于陈述句，表示否定)，ever（多用于疑问句），yet(多用于否定句表示“还（没）”；用于疑问句表示“已经”)，just(位于谓语动词之前)，before(一般位于句末)。
2.—I really hate to go to such a place .
—So do I. 我也是。
—No one likes “Little Emperors”.
—Neither do my parents.
So do I.为倒装句，表示前面提到的肯定情况也同样适合另外一个主体，意为“ 某某也一样”，结构为“so +be/助动词/情态动词 +另外一个主语”。此句所用的时态要与前句的时态相同。表示前面提到的否定情况适合另外一个主体，结构为“neither/nor +be/助动词/情态动词+另外一个主语”表示“……也不这样”。
--Tina isn’t a lazy girl.
--Neither/nor am I.
3. At that time, China had the largest population in the world and it was not well developed .
