³3)2 Common Grammar Errors.For many students ,two aspects of grammar that are a particular problem are; with prepositions, articles, verbs, adverbs.
Prepositions
There are two specific prepositions that you will probably use numerous times in your Task 1 essay when reporting change –‘in ’and ‘of’. They are easy to get wrong. Follow this general rule: When stating the specific value of the change (number, amount ,percentage, etc.)-use’ of’. When stating what has changed –use ‘in’. For ex; An increase of 20%. An increase in the number of over 60’s taking exercise classes. An improvement of 45 units per week. An improvement in retail sales from April to June. ‘Of ‘ is also used after a value. You will probably want to use proportional values in your Task 1 essay here some examples. A small percentage of, just under a quarter of, exactly a half of ,roughly three quarters of, a significant majority of, a high number of etc. You will find lots more vocabulary for expressing proportional values in Writing IELTS Task 1 essays on this page: Vocabulary for Task 1 Academic Essays. Another preposition to learn is ‘between’ which you will need to make comparisons. For ex: The price of houses went into sharp decline between 1980 and 1985 but increased significantly from 1986 to 1990.
Articles
Many languages do not have articles ,and native speakers of those languages can find it a huge challenge to remember to use them . In English ,there are three articles –the ,a, and an. Each is used in specific instances. 1)With singular and plural nouns: Use the before singular and plural nouns when the noun is a spec thing .For ex: The bar graph illustrates how many male and female students were studying full-time and part-time in Britain during the years 1970/1971, 1980/1and 1990/1. Use a or an before a singular noun or noun pharase when the noun is non-specific and could be any one of a group or type. Use a before a noun or noun phrase beginning with a vowel. For ex: Less than 30%of the population took a foreign holiday between 1975 and 1985. There was an upward trend in families taking an annual holiday abroad after 1990. 2) Noun combinations:
Also, use a/an before adjective singular noun combinations such as these from our preposition list: a small percentage of ,An insignificant minority of, a high number of
The key to improving your grammar is to know your weaknesses and focus on these as yiu practice and when you check your work in the exam.
