All the useful energy at the surface of the earth comes from the activity of the sun. The

sun heats and feeds mankind. Each year it provides men with two hundred million tons of grain and nearly ten million tons of wood.

Coal, oil, natural gas, and all other fuels are stored-up energy from the sun. Some was collect ed by this season's plants as carbon compounds. Some was stored by plants and trees ages ago.

Even waterpower derives from the sun. Water turned into vapor by the sun falls as rain. It courses down the mountains and is converted to electric power.

Light transmits only the energy that comes from the sun' s outer layers, and much of this energy that is directed toward the earth never arrives. About nine-tenths of it is absorbed by the atmosphere of the earth. In fact; the earth itself gets only one half-billionth of the sun' s entire output of radiant energy.

A．directly from the sun

B．from the sun' s activity

Propositional Meaning

Propositional meaningis also referred to assentence meaning. To know the meaning of a sentence is to know what the sentence is all about, and what, who, where, when and how are involved. The following sentences differ in their structure, but they share the same propositional content:

Her colleague regard her as being less than bright.

She is regarded as being less than bright by her colleague.

She strikes her colleague as being less than bright.

In other words, the above three sentences can be used to paraphrase each other's propositional meaning, and therefore paraphrasing becomes a very useful device to help us to check our understanding of the propositional content of a sentence.
