When children first learn to talk, thereare some sounds that they find _______ to articulate.

A. difficult  B. it difficult

这是很常见的高考考点，答案为A。因为本句中find已有自己的逻辑宾语，即上文中的定从先行词sounds,如果改为一个简单句应为：They find some sounds difficult to articulate.此句中的find sth + adj.为其复合结构，如果选B，则混淆了find后跟形宾结构，若it为形宾，那真正的宾语只能为其后的不定式，但是正如我上文所讲，find自身已有逻辑宾语，不可能为不定式，因此B是错的。

类似题：

Arabic is a language I found ______ to learn.

A.it is difficult B.it difficult C.difficult D.is difficult
