Televisions enable us to see things happen almost at the exact moment____.
A.\x05which they are happening B.they are happening　　
C.which they happen D.they have happened

Answer 1

1.D
as 引导的让步状语从句要倒装
2.C
这是一个独立主格结构,There having been no rain 的完整结构是There has been no rain
主语是 no rain
两个部分因为主语不同 加之是主语+非谓语形式(可带宾语）故可以判断为独立主格结构；
使用完成时是强调未下雨对田野的影响.
3.B.
at the exact moment
在此作为连词,其后可以直接加；一个完整句子they are happening　　
类似的还有 the moment / the minute / immediately等词
若去掉at 会更恰当些.
A.which they are happening 若把which改为when就是一个定语从句了.
选现在进行时的原因在于强调那个时刻的动作.
moment引导同位语从句这个说法是错误的,作为同位语从句必须是说明名词内容的,一般moment后也不加同位从,其后加同位从的名词有 information / news / ideas / suggestions etc.
