请教以下英语句子
If Martin is correct,trying to tune this stuff out is about to get a whole lot harder.
逗号前面我做了改动,主要是逗号后面不明白,麻烦翻译一下.
You might expect optimism to erode under the tide of news about violent conflicts,high unemployment ,tornadoes and floods and all the threats and failures that shape human life.
这里shape human life 翻译成什么?
The major problems include the rising cost of doing business—thanks primarily to new regulation requiring banks to hold more capital and liquidity to ensure that the industry better withstands future shocks—scarcity of capital and liquidity,changing consumer behavior as a growing number of customers move to mobile and online channels ,and diverging regional growth paths.
原有的中文翻译大致是这样的：这个主要问题包括成本的增加,这个成本的增加是新规定要求的怎样怎样以确保承受未来的冲击,这个冲击又包括资金不足、消费者行为转变和什么什么.
也就是说,这个翻译表示这句话第一个破折号后面解释说明第一个破折号前面,第二个破折号后面解释说明前面,是一层层递进的.
我想问,为什么不能把这两个破折号之间的内容当做插入语去掉,使the rising 、changing、and diverging 作为The major problems 并列的内容?当然如果这样理解的话,第二个破折号后scarcity of capital and liquidity我又不知道它处于什么地位了.
