1,am 这个句子的动词使用就近原则,靠近的是I,所以用am
2,finishing upon是介词,介词后面的动词要用动名词形式
3,for it is+形容词+for sb to do sth.这是固定搭配,做某事对于某人来说很……
希望能对你有所帮助
AAD
B
either ……or……谓语动词就近原则，与I保持一致
A
upon是介词，+动名词
D
it is + adj +for/to sb to do sth.对于某人来说干某事是怎么样的
用for时，形容词是来形容这件事的
用to时，是用来形容人的品质的。
B (主谓一致的就近原则)
A （主从句主语相同）
D
1、B either.....or ... 谓语动词看or的主语
2、B 过去式做状语
3、D be necessary for 是固定搭配
建议你多翻翻语法，看起来就简单了
