A. for
B. of
C. at
D. on
为何选AB???

Answer 1

1.首先，固定搭配be different from,所以先排除D，然后因为前半句去掉主语life today(today修饰life)different是形容词，对形容词提问用how,排除BC。
翻译为，现在的生活和三十年前相比是多么不同。
2.固定搭配be of great benefit意为拥有巨大的好处，例如be of great value,意为有很大价值。
解释不好还请多多原谅，毕竟我才初三。

Answer 2

都是感叹句
第一个,修饰"different",所以用how,from 与diferent是固定短语

第二个，be of 也是固定用法，“be of great benefit”
