在书上看到一句例句如下 One of Chomsky's achievements has been to make plausible the claim that linguistics is scientific in the more interesting sense that it can provide no t only explicit descriptions but also explanations for the classification. 有几个疑问: (1) 我对于be to + v.的理解是做为“未来式”使用或用来表示“条件句的先决条件”， 但此处搭配完成式has been to make，实在百思不解例句要表达的意思orz (2) make plausible the claim that...... v. + adj. + n.这样的倒装用法是否只能限定在使役动词使用呢? 先感谢大大赐教~~
