图片上的题

1. 第一个空是过去分词短语做伴随状语，因为地球是被看的，所以用了被动形式seen；而第二个空是with的复合结构，水覆盖在地球上是主动，所以用了covering
   

2. 这里的cover是报道（新闻）的意思，这句话的意思就是“我想让我们最好的记者去报道这个审判（或者宣判）”

下面的题

1. 选b 固定句式 all that...第一个that引导定语从句修饰all，all that=what，比如这句话就可以改成What is important is that you are doing your best and moving in the right direction .

2. 选c 搭配argue with sb. about/over sth。about which 引导定语从句修饰subject
