Question

1.many lifestyle patterns do such____great harm to health that they actually speed
up____weakening of the human body.
A.a;/ B./;the C.a;/ D./;/
2.Her son,to whom she was _____,died two years ago.
A.loved B.cared C.devoted D.affected

Answer 1

1.B
harm为不可数名词,前面不能加a,且有固定短语：do harm to...“对...有伤害”；
第二空,特指“人体的虚弱”,所以前面加上定冠词the.
2.C
楼主要理解定语从句的含义.
to whom she was dovoted
= she was devoted to whom
= she was devoted to her son.
固定短语：be devoted to...“致力于/献身于/专心于...”.
如果用B,则变成：she was loved to her son,句意不通,如果说成she was loved by her son还差不多.
