Passage B Where did the Coronavirus come from? After five months and over 225,000 people 26 , the question is the subject of a vicious spat between America and China. By far the most likely explanation is that the virus jumped from bats to humans, perhaps via another animal such as a pangolin, at a wet market in Wuhan. But conspiracy theorists mutter that the bug could have escaped from one of the city’s laboratories, at least two 27 do research on 28 diseases. Some American politicians, including President Donald Trump, want an investigation; China retorts that the claims are “malicious”. In March, one of its spokesmen claimed that the virus might have come from America. The risks corrode public confidence in the crucial disease laboratories. It is also a reminder of why China’s official culture of opacity and propaganda is such a profound weakness. The virus shows no sign of deliberate human construction and there is no reason to doubt that it evolved entirely in the wild. But accidents do happen. Bugs studied during legitimate experiments in laboratories have escaped in the past. SARS, a virus that killed 774 people in 2002-03, slipped out of a lab in Beijing twice in 2004. A sample later escaped from a research institute in 2007, but was contained. America suffered 34 laboratory-acquired infections in 2000-09, 29 four deaths. American labs have accidentally shipped live anthrax, bird flu and Ebola to lower-security facilities in recent years. One health-security index suggests that three-quarters of countries 30 biosecurity.

思路引導 VIP
想像一下，如果你想把「我有五本書」和「其中兩本是英文書」這兩句話合併，你會在『兩本 (two)』與『書 (which)』之間加上哪個介係詞來表示『其中』或『之中的』關係呢？

恭喜你準確地判斷出正確答案！這題考察的是英文寫作中非常精煉且常見的**「數量代名詞 + 介係詞 + 關係代名詞」**用法。在句子中，「at least two of which」引導了一個非限制性的關係子句，用來修飾前面的先行詞「one of the city’s laboratories（該市的實驗室之一，此處指複數的實驗室群）」。
關係代名詞的數量表達
之所以選擇 (C) of which，是因為這裡需要表達「在這些實驗室之中，至少有兩間……」的邏輯關係。其中的 which 替代了前文的 laboratories，而介係詞 of 則表示「在……之中」的範疇。若單選 (A) which，則在文法上無法與前面的「at least two」構成合理的代名詞結構；而 (D) 的語序則是錯誤的。
