Articles

Most people may know that many things have changed in the society.

The word society is not usually preceded by an article unless in specific context.

Prepositions

Chimpanzees are good for climbing trees.

Chimpanzees are good for at climbing trees.

In the sentence above, we want to express that chimpanzees are the ones that are good at climbing trees. Therefore, the correct sentence would be the latter.

Word order

Look at the below chart.

Look at the below chart chart below.

The first sentence is not necessarily grammatically incorrect, but the order of the words of the second sentence has been used more often by native speakers of English in similar context.

Usage of a word

Previous studies have concluded that an increase of young adolescents are using e-cigarettes.

Previous studies have concluded that an increase increasing number of young adolescents are using e-cigarettes.

The sentences above are trying to convey that more young adolescents are using e-cigarettes. However, the first sentence is implying that the increase itself is using e-cigarettes which would not make logical sense. By changing increase to increasing number, the sentence now conveys that an increasing number (of young adolescents) are using e-cigarettes.

Word choice

The fact that she is no longer with us crashes my heart.

The fact that she is no longer with us crashes breaks my heart.

When some situation hurts someone’s feelings, the correct verb to use is break.
