1. Perhaps things might be better between the two of them if Mary accepted Elizabeth's choice of a safe Protestant husband for her in the winning form of Robert Dudley.

結構剖析：這是一個含有分隔式同為語從句的復合句。主句是：
Perhaps things might be better between the two of them；分隔式同位語從句是：if Mary accepted Elizabeth's choice of a safe Protestant husband for her。

先看主句：主語是things，謂語是might be better。其余的都做狀語，perhaps是副詞做程度狀語，between the two of them是介詞短語做狀語。

（2）再看從句：這個同位語從句的引導詞是if，它是具體意義的，意思是“是否”，能省略的。

從句中主語是Mary，謂語是accepted，賓語是choice，這里有3個定語都是修飾choice的：Elizabeth's（伊麗莎白的） 、of a safe Protestant husband（可靠的清教徒的丈夫）和介詞短語for her（為她）。

2. One tiny problem with this plan, though, Mary had no intention of being told what to do by Elizabeth.

結構剖析：這是一個含有表語從句的復合句。主句是： One tiny problem with this plan，表語從句是 Mary had no intention of being told what to do by Elizabeth。此外，though在這里是做副詞用，意思是“但是”。

在表語從句中，介詞of的后面接的是動名詞短語，這個短語使用的是被動語態——being told what to do by Elizabeth，進而來看這個動名詞短語，它其中含有一個不定式——what to do，它做賓語。
