40. “The City of London” actually refers to only a small part of London, ________ there is a concentration of banks, insurance companies and financial markets.
(A)when
(B)which
(C)where
(D)with which

“倫敦金融城”實際上是只指倫敦的一小部分，那裡是銀行，保險公司和金融市場的集中之處。（A）…之時(關副)（B）哪一個(關代)（C）…之處(關副)（D）隨其；因其(with+關代)

“The City of London” actually refers to ～ + and there is ～

=“The City of London” actually refers to ～, where there isn～

=“The City of London” actually refers to ～, which is ～

空格前後分別是兩個帶有主詞和動詞，並為完整句子，空格處則需用連接詞性來表達前後句意。依題幹選項可知考關係詞，推出後句須對前句修飾之用，選where為關係副詞，用來表示說明某地點或某場所(即後句指出的there is修飾前句的The City of London)。

雖然關係副詞where= in which，但因前面有逗號區隔，此為「非限定用法」，故只能用which補述先行詞The City of London，其作為後句的主詞，而不用以修飾或限定前述詞，故一個句子只能有一主詞和一動詞的情況下，重複的主詞there須去除，還有關係代名詞that不可用於補述用法，用於補述用法的關係代名詞不可省略。

整理以上說法

(A)(C)

這題是一個補述用法

最佳解到底是在說 where 還是which?這題答案不是where 嗎?

=

“The City of London” actually refers to only a small part of London and there is a concentration of banks, insurance companies and financial markets.

PS.這題答案是where沒錯，7Fzoe的回文被讚到最佳解前，一開始是回答6F好想金榜題名的疑問，為什麼若是想選(B)which，那題幹不能出現there的原因；除了知道正確答案的用法，也教導錯誤答案是錯在哪，要怎麼改正。
