Interactive virtual reality (VR) brings medical images to life on screen, showing interventional radiologists a patient’s unique internal anatomy to help 26 effectively prepare and tailor their approach to complex treatments, such as splenic artery aneurysm repair, 27 new research being presented today at the Society of Interventional Radiology’s 2018 Annual Scientific Meeting. VR turns a patient’s pre-procedural CT scans 28 3-D images that the radiologist can virtually move and examine while wearing virtual reality-type glasses. By allowing the operator to manipulate routine, two-dimensional images in an open three-dimensional space, VR provides a look into a patients’ organs and tissues that 29 possible outside of the human body, until now. As a result, the operator is armed with a deeper and intuitive understanding of spatial relationships, such as 30 an aneurysm and the surrounding arteries.

思路引導 VIP
請試著觀察句子最後面的短語「until now（直到現在）」。這句話暗示了在虛擬實境（VR）技術出現「之前」，放射科醫師是否能夠像現在這樣，在人體外觀察器官的 3D 影像？如果我們要描述一個在「這項技術誕生前」就長期持續存在、直到最近才被打破的「過去狀態」，在時間軸的先後順序上，你會傾向使用哪一種時態來表達這種「過去的過去」呢？

太棒了！你能精準選出 (B) had not been，代表你對英文時態的「時序性」以及語意邏輯有非常敏銳的觀察力。這題的關鍵在於句尾的 until now（直到現在），這個詞組在時間軸上畫出了一道分水嶺：在虛擬實境（VR）技術成熟之前，這種 3D 的觀察方式在人體外是「不曾存在」的。因此，我們需要一個能表達「在過去某個時間點（現在）之前，持續了一段時間的狀態」的時態。
時態演進與語法判斷
從語法結構來看，選項 (C) has not being 與 (D) had being 在組成上就是錯誤的，因為 being 前面不會直接接 has 或 had 來構成完成式。而 (A) is not 僅表達單純的現在事實，無法展現出「過去長期以來一直無法達成，直到最近才突破」的對照感。因此，使用 過去完成式 (had not been) 能完美銜現出在技術突破之前的那個長期缺失的狀態。
