答案

1.B
由句中的will可知,该大坝尚未完工,所以是“到2010年将要被完工的大坝”,即the dam to be completed by the year 2010.
to be completed by the year 2010为不定式的被动结构作后置定语,修饰the dam,表示该动作（be completed）尚未完成.
如果用A completed,则表示“已经完工的大坝”,错误.
再如：the meeting to be held“将要举行的会议”；
the meeting held“已经举行的会议”.
2.going on为现在分词做宾语补足语,形成介词with的复合结构即：介词with + 宾语all that noise + 宾语补足语going on.
因为此句中含有一个谓语couldn't do,所以go on不能再做谓语了,只能用其非谓语形式.
因为宾语all that noise和go on之间是主动关系且已经发生即“噪音正在进行”,所以用现在分词going on.
3.C
不定式短语做句子的结果状语,表示出乎意料的结果,其前面一般会加上only,意思是“结果只是...”.
翻译：他匆忙赶到车站,结果只是发现火车已经离开了.
4.B
非谓语动词做状语,需要考查非谓语动词wait和句子主语Tom之间的关系.这两者之间明显是主动关系,所以用现在分词waiting.
又因为wait该动作发生在谓语动词realize之前,所以用其现在分词的完成形式having waited.
不定式放在句首,一般只做目的状语,翻译成“为了等...”,句意不通.
5.A
答语之间有个and连接,所以前后都是独立的句子.
而and之前的句子没有谓语动词,所以know就是该句的谓语,因此只能把它视为是祈使句,以动词原形know开头.
6.固定搭配：the answer to this question,不能用of.
楼主记忆有误,类似结构还有很多,如：the key to my door/bike“我家门/我自行车的钥匙”等.
这是固定搭配,楼主记住就是.
