Hello, everyone!<br/><br/>I am thinking about 'preparatory it' and I'm not sure when to use it.<br/><br/>Examples :<br/><br/>1. I find <b>it</b> interesting <b>to talk to him</b>.<br/><br/> =&gt; I find <b>to talk to him</b> interesting. (O, X)<br/><br/>2. I find <b>it </b> interesting <b>talking to him</b>.<br/><br/> =&gt; I find <b>talking to him</b> interesting. (O,X)<br/><br/>Two sentences above ,without 'preparatory it' are grammatical?<br/><br/>If not, why?<br/><br/>Gooday!
