________different life today is from__________was a century ago

________different life today is from__________was a century agoA.what a what B.what how C.how what D how how 请说明理由选A；what a different =how different a 感叹句型；后面What作宾语从句 很高兴为您解...可答案是C知道了，这里的life指生活，不需要用a修饰，所以直接用how 修饰different 即可那为什么不能选B，what different life/today is fromhow was a century ago这样来看what 做的是from后面的宾语，how不能作为宾语，谢谢
