Every once in a while you will read some article about a so-called scholar unearthing material that is supposed to prove that William Shakespeare did not really write the works attributed to him. Many alternative authors have been suggested most prominently, Christopher Marlowe Francis Bacon. One proponent of Bacon as author of Shakespeares plays actually looked for words like "fat and lard" and calculated how their places in the texts of the plays proved that Bacon authored them. Any schoolboy can see the fallacy of such an argument and yet many adult readers of newspaper articles, written by men who have never done any research on Shakespeare, are taken in by the arguments proposed against Shakespeares authorship. It is true that we have no manuscripts of the plays as they came from Shakespeares hand. After all, he wrote the plays to be acted, and the actors used the authors manuscripts. However, almost half the plays appeared in print under the authors name during his lifetime which ended in 1616. A few years later, in 1623, two of Shakespeares actor friends published a great folio(对开本 ，对开的)volume with thirty-six plays and put Shakespeares name on the title page. They even got Ben Johnson, Shakespeares great rival playwright, to write a poetic introduction for the folio volume. There are other arguments I might adduce(引证)to vindicate Shakespeares authorship. Suffice it to say, a blanket argument against those who deny Shakespeares authorship is simply this: If Shakespeare did not write the plays attributed to him, it was someone else by the same name.The main idea of the first paragraph is that______.A．some scholars have proved that Shakespeare"s works were not his ownB．some scholars do not believe Shakespeare"s works were his ownC．some pseudo-scholars try to prove that Shakespeare"s works were not his ownD．some pseudo-scholars take it for granted that Shakespeare"s works were his own
