1. "I will have received my promotion <b>by</b> next November"<br/><br/>2. "The train will have left <b>when</b> you arrive"<br/><br/>3. "Will she have learned enough Chinese to communicate <b>before</b> she moves to Beijing?"<br/><br/>Hi, are <b>by</b>, <b>when</b> and <b>before</b> the only conjunctions used to make a link with a clause containing future perfect tense? Or did I miss a few others?<br/><br/>Thank you
