一些新的顧慮涌現(xiàn)出來，成了我們如何對待孩子的爭論的一部分。
點睛本句的主干是A new set of considerations has come to the fore。as part of...為補語，其中how引導的是介詞about的賓語從句。
set在此處為名詞，意思是“一組，一套”。如：
He gave me a set of Dickens' novels as my birthday present. 他送給我一套狄更斯的小說作為我的生日禮物。
come to the fore的意思是“突然出現(xiàn)，脫穎而出”。如：
After the election several candidates came to the fore. 選舉后，幾位候選人脫穎而出。
考點歸納不僅僅動詞有賓語從句，介詞也有賓語從句，介詞賓語從句的引導詞有以下幾種：
that引導介詞賓語從句，但僅限于用在except，but，notwithstanding等少數(shù)介詞后。如：
He would have helped us but that he was short of money at the time. 要不是他那時缺錢，他一定會幫助我們的。
連接代詞和連接副詞引導介詞賓語從句。如：
I have no definite information yet as to which route he will take. 對于他要走哪條路線，我還沒有確切的信息。
名詞性關系代詞what，whatever，whichever，whoever引導介詞賓語從句。如：
The boy was interested in whatever he saw here. 那孩子對在這里看到的任何事物都感興趣。
The first prize should go to whoever writes best. 一等獎應頒給最優(yōu)秀的作者。
