現在完成式v.s現在完成進行式

版主說的沒錯，用「現在完成進行式」會比較符合題目的要求，因為原題前半段就已經強調她現在仍然在公司工作，也就是說從過去的一個時間點開始，到目前狀態仍然持續著，眼前尚未有終止的跡象。

She has been working in this company since she graduated from college.
她從大學一畢業，就一直在本公司工作到現在。

若老師意思不是強調狀態持續中，那請參考意見欄裡BEN, Beth大大們的看法。
若能加上一段期間明確表示完成之意，那就不會混淆了。

She has worked in this company for ten years since she graduated from college.
從她畢業到現在已在公司待10年了。

如果使用現在完成式, 通常語意上是要表達和現在的關係. 也就是說,
She has worked in this company since she graduated from college.
翻成中文是
他從畢業後, 就已經在這公司上班了.
She has been working in this company since she graduated from college.
他從畢業後, 就一直在在這公司上班.

從單句的意思來看可能沒有太大差別, 但是如果後面還有句子, 就可以根據後面的語意選出哪一種時態比較適合.
She has worked in this company since she graduated from college. Maybe it's about time for her to make a change.
She has been working in this company since she graduated from college. She knows everything about this company.

====== She is working in this company,she works here since she graduated from college. =====

很簡單,因為這句是 (( is working )),所以當然要使用==>>現在完成進行式.
如果是==>>現在完成式,則表示現在已經完成了,也就不能是(( is working ))了

所整句改成如下

She has been working in this company for 10 years since she graduated from college.

==== 考試的答案是現在完成式捏 ====
==== 老師的答案是說這題強調"他開始工作的時間點" 並不是持續性 ===

Ans:
考試的答案是錯誤的
你老師的說明也是錯的

我覺得兩個都可以耶
我覺得she has worked in this company since she graduated from college
比較沒有強調，就很平淡地說大學畢業後就在這間公司服務

She has been working in this company...
則比較強調，大學畢業後到現在，她一直都在這間公司服務

不知道這樣解讀是否正確?
