    優(yōu)質(zhì)解答
    1.() is known to us all是句子主語,稱作主語從句.能引導(dǎo)主語從句,又在從句里做主語指事或物,用what.
    2.(1)如果選A項it,則去掉第二個is才可以.這樣變成了it作形式主語,that the 2008 Olympic Games will take place in Beijing是真正主語.It is known to us all that the 2008 Olympic Games will take place in Beijing.
    (2)如果選C項as,則變成由as引導(dǎo)的定語從句,但要用逗號隔開.
    即:As is known to us all ,the 2008 Olympic Games will take place in Beijing.
    (3)如果選D which,則也變成定語從句.which引導(dǎo)的定語從句不能位于句首
