总结：

1、表达“某人因为......而无法做到”，惯常思维会让人写出这样的句式“sb. cannot do...because...”, 可这种表达太普通，要学会使用以下句式：“sth. prevents sb.'s+ 名词”。尤其是原句can后的动词很容易转化成名词时，更应该用这个新句型。

2、学会用“in the hope of", "in the belief of ","in the discovery of ","in an attempt to"等经典短语，将以“同样主语+hope/believe/discovery/try"等开头的另一句与原句相连，从而构造出一个更紧密地长句。另一句与原句之间可以是目的、原因或伴随关系。
