Logically C is true cos shade definitely will block off sunlight and cool down the temperature.
And that has nothing to do with the ozone layer which is another story.
Ozone layer problem mainly concerns UV light radiation and not global warming.

So I think it's 4.

Thanks to all for your contribution. After my son read, he said he agreed 4 is the answer. Thanks again!

'gai bian' is a verb which is neutral, therefore its proper use depends on the sentence structure. In the question, it was mentioned ' the smile ' .....then 两个朋友之间不愉快的心情, meaning the the proper verb should one which has positive impact to the unhappiness.

In that case, ' xiao chu' which means eliminate is proper.

Perfect explanation!! :goodpost:

You can only \"消除\" 两个朋友之间的不愉快 but you cannot \"消除\" 不愉快的心情. 心情 cannot be \"消除\", it can only be \"改变\".

Ozone layer only absorbs/blocks the UV rays and does not affect the heat coming into earth

Direct rays(or UV rays) is not heat
So the sun's heat will get directly into earth but the UV rays will be partially get into earth

[quote=\"PsleStudent\"]The gas called ozone protects the earth from the direct rays from the sun by forming a layer in the atmosphere. If not this layer the heat of the sun will get to the earth directly. When this ozone layer is depleted through the action of some chemicals man has no shelter again from the ultraviolent rays of the sun which can cause sunburn and skin cancer. There are also other negative effects of this ray from the sun.

But is the ozone layer completely depleted? If not, then the sun won't directly heat the Earth, right?

hmm... As for that i think for that, your opinion should be correct. As i think the ozone layer is not COMPLETELY depleted,there will still be a shelter but i think there would be more UV rays passing through the ozone layer? i am also not so sure about that... [/quote]
