the week before......
a week before 不等于 the week before. a week before中，中心词为before，a week是修饰语，即7x24小时以前。而 the week before中，中心词为week, before为修饰语，意为，前一周，上周，这周中的某一天或整个一周。例如下句：He'd been driving Kim to school every day the week before he left. 他离开前那一周每天开车...

think of A as B. as B整体为宾补。通常认为这里as为介词，可以后接名词，形容词，过去分词，doing。当as后接形容词或过去分词时，被认为省略了being. 类似的结构如：see A as B, describe A as B, accept A as B, consider A as B, refer to A as B等。as B 都是宾补，对宾语作说明。 你的句子可以翻译为：很多人认为...

no+名词+need
preside over sth 本义为主持（会议），负责（某事），人做主语。这里是引申用法。need为情态动词，用于否定和疑问句。句子意为：不需要A、B 或C来负责消除这样的危险。消除这些危险不需要任何愤怒、报复或道德自负。
