hi,
i have problems about the usage of definite article!
first one is this sentence:'the discovery of elementary particles'. shouldnt it be like 'the discovery of the elementry particals?' which one is right?
second question is about the word earth.i see this word taking definite article like 'plastic materials buried in the earth' and not taking any article in 'radio waves transmitted from earth'. what is the differance?
any help?
regards;
