Grammar in context Complex subject Chemistry is often said to be the central science. Modal verbs Ancient man must have wondered what happened to the wood he

burnt Past Simple vs Past Perfect Although Lavoisier was the first to publish his ideas, Lomonosov had

reached the same conclusions some years earlier Constructions with infinitive Even while chemists were divided on atomism, it became necessary

for someone to make senses of the growing list of elements Emphatic constructions It was by burning things that ancient man discovered iron and glass Inversion So accurate was his classification of the elements, that he was able

to predict the properties of undiscovered ones.
