1.Entering the office this morning, I found Bob___at the desk, __in thought.

第一個(gè)空是答案是seating,第二個(gè)空是Lost,我想問第一個(gè)空為何不需要seated 呢，或者把found 后面看作是省略that的賓語從句，填was seating,我的這兩個(gè)答案為何不對(duì)呢。


2.The government managed to have two chemical factories built,thought________by the citizen.

答案是opposed to ,為何不選having been opposed to 呢，有空閑先后。


3.The collision of cultures between the two countries led to many nations ______actions against them.

答案是taking ，taking actions 做的什么成分?

1 第一個(gè)空應(yīng)該用seated 或者sitting。seat是及物動(dòng)詞，意為使賓語坐下。所以用seating或者was seating都是不對(duì)的。

2 thought應(yīng)為 though（雖然）。這是讓步狀語從句省略了 it was. 這種讓步狀語從句的省略需要是主語和 be 同時(shí)省略。

3 lead to為短語動(dòng)詞，= result in，意為致使，引起，后接名詞性結(jié)構(gòu)作賓語。many nations taking actions against them 為動(dòng)名詞復(fù)合結(jié)構(gòu)作led to的賓語，其中many nations為動(dòng)名詞的邏輯主語（動(dòng)名詞復(fù)合結(jié)構(gòu)作介詞賓語時(shí)，動(dòng)名詞的邏輯主語一般用通格而不是所有格）。
