1. Read the sentences and determine relationships between the parts in each sentence.

§ Innumerable benefits include not only new materials, food additives, and pesticides, but also new analytical tools for the study of living matter.

§ The scientists have made the progress that has provided unforeseen power, which enables us to change our lives, our world as well as our future.

§ Because of its precision, mathematics is an essential tool for all of the sciences.

Showing relationships between ideas To connect words and phrases that have the same grammatical function in a sentence we use conjunctions, prepositions and adverbs. § conjunctions* e.g.: The twentieth century saw much momentous change that either brought enormous benefits to human beings, or threatens the very existence of the human species.
Both … and … when connects two subjects require plural verb
Not only … but also … Either … or … Neither … nor … when connects two subjects, the latter determines whether the verb is singular or plural  
* The samegrammatical form should follow each word of the pair. Neither … nor …is already negative in meaning so doesn’t require negative form of a verb   § prepositions e.g.: Apart from large-scale research programmes, scientific research with little short- term economic profit may be called into question.
Because of … Due to …*     are followed by an object noun show cause and effect
Apart from … Except for … In addition to … show contrast
continue the same idea

 

Due to … in formal writing is followed by a noun clause introduced by the fact that   § adverbs e.g.: The chemical sciences developed new analytical tools for the study of living matter as well as the environment.
As well as is usually followed by an object noun indicates addition

 

 

 

Practice

1. Change the sentences using an appropriate conjunction, preposition or adverb. Translate the sentences into your native language.

a) Big cities suffer from air pollution. They also suffer from the shortage of fresh drinking water.

b) Nowadays biochemistry doesn’t provide an answer to the fundamental question of the generation of life on earth. Modern biology doesn’t answer this question either.

c) The research project will be funded from one of the sources: local or national.

d) The research project took a lot of time and much money.

e) The cost and size of computing power has been reduced. The design and implementation of the Internet allows access to information from all over the globe at an unprecedented level and speed.

f) Discovery and study of quasars, black holes and pulsars were made possible by new observation instruments.

g) The concentration of atmospheric carbon dioxide (CO2) is increasing because the vast amount of fossil fuels is burnt every day.
