我們被告知,即將舉行奧運會的建筑甚至會比那個更好.
we were told (that)是主謂賓結(jié)構(gòu)的被動語態(tài),“我們被告知”,這里的賓語that 被省略了,后面的是解釋“that”—>我們被告知的內(nèi)容.that 引導的是一個從句（好像叫同位語從句：具體的我不太確定,不好意思……）.
the buildings 是從句的主語,where引導地點狀語修飾buildings放在后面.the Olympic Games would be held 就是整個狀語,正常的語序是Olympic Games would be held in the buildings.這個句子用的時態(tài)是過去將來時（我們在【過去的時間】被告知這個建筑【將要】舉行奧運會）,因為用前置的地點代詞where代替了in,所以句子倒裝了.
去掉地點狀語的句子是：The buildings were even better than that.這個句子就是由被省略的that引導的內(nèi)容,是一個主系表結(jié)構(gòu).
所以整個句子是這個樣子的：
We were told 【the buildings [where the Olympic Games would be held] were even better than that.】
【】外面的是主句,里面的是從句,[]是從句的地點狀語.
