Answer 1

1.选C.
解析：此题考查“get + 宾语（the harbour）+ 宾补（过去分词短语completed within half a year)" 的用法，意思是“让某人做某事”。宾语和宾补之间是动宾关系，故用过去分词短语做宾补，表被动。再如：I will get my computer repaired this afternoon.不过，此题宾语和宾补之间被which引导的非限制性定语从句隔开了。
翻译：让人震惊的是市长让人半年之内把港口建好，这座港口对当地经济的发展有很大益处。
2.选C。A也正确，不过C更常用【有些辞书倾向于with后接名词或代词，其实接动名词很常见】。
此题考查非谓语动词短语作状语的用法，因为occupy和句子主语He之间是动宾关系，故使用过去分词短语作状语。occupy oneself in 【被动形式be occupied in】和occupy oneself with 【被动形式be occupied with】均是“忙于...”之意。
如：1）On long car journeys I occupy myself with solving maths puzzles.
2）He hurried to take the suitcases and occupy himself with packing the car...
3）He occupied himself (in) writing a mystery story.他埋首于推理小说的写作
3.选B。
解析：考查非谓语动词短语作状语的用法，因为occupy和句子主语He之间是主谓关系，故使用现在分词短语作状语。因为是名词the project，故选B较佳，如接动名词则选D更好，见上题分析。

Answer 2

C 其他几项都是现在或将来时，只有C过去时，前面was要求用过去式吧
C be occupied in ,省略主语
B occupy sb with sth
