请大家从英文语法的角度给我讲解一下这四个句子~
1.It experienced enough failures to cause serious doubts about gene therapy ever being worthwhile.（不懂to和being的语法构成）
2.Out of the diversity more than 30 countries and almost as many languages,a generation appeared that felt itself to b truly American.（不懂as和truly而不是true的语法构成）
3.There is a tendency among nonexperts to regard primary health care in developing countries as exclusively for the prevention of disease.（不懂exclusively而不是exclusive的语法构成）
4.Ten months later,the children's immune systems appeared to be functioning normally,evidence that the normal gene had taken over the work of the defective one.（我觉得evidence应该改为evidencing）

1.enough ...to,失败次数多到...程度；gene therapy ever being...动名词从句,做about的宾语,也可以说成 gene therapy's ever being ...
2.as 表示同等比较,指有相同数目的语言,即30多种语言；truly副词修饰形容词American
3.这里要用副词,修饰整个短语,相当于only
4.这是一个比较松散的说法,指前面说的事是个证据,其后的that从句是其同位语
