[請益] TPO18 Lightning
Most lightning takes place within a cloud when the charge
separation within the cloud collapses. However, as the storm
cloud develops, the ground beneath the cloud becomes positively
charged and lightning can take place in the form of an electrical
discharge between the negative charge of the cloud and the
positively charged ground. 【Lightning that strikes the ground is
the most likely to be destructive】, so even though it represents
only 20 percent of all lightning, it has received a lot of
scientific attention.
21. the author mark "Lighting that strikes the ground is the most likely
to be destructive" in order to explain
(1.) this form of lightning has been investigated so much
(2.) this form of lightning is not as common as lightning within a cloud
(3.) scientists understand of this form of lightning is important
(4.) the buildup of positive charge on the ground beneath a storm cloud can
have serious consequence
答案是 1
照字面上的解釋
"這種打到地面的光是有毀滅性的"
是這樣翻嗎?
我自己是寫4
看不出跟答案之間的關連性
麻煩高手解惑!!!
