Hello!<br/><br/>My exercise book writes that 'as' can mean 'even though' when the structure is like;<br/><br/><font color="#0000ff">1. adjective + as + subject + verb</font><br/><br/><font color="#0000ff">2. adverb + as + subject + verb</font><br/><br/><font color="#0000ff">3. noun (without any article) + as + sbuject + verb</font><br/><br/>1. and 2. are OK. But in 3. what if there comes a noun with an article, for example,<br/><br/><font color="#ff1493">A boy</font> as he is, he knows well how to deal with people.<br/><br/>Is the sentence wrong?<br/><br/>My book says it's wrong. It should be ' <font color="#ff1493">Boy</font> as he is, he knows well how to deal with people.'<br/><br/>The book might be right. But there is no book with no flaw(my opinion). So, I just want to check it.
