One of the most common mistakes we see in ESL students’ writing concerns doubling the last letter of a verb when we add “-ing” or “-ed” to it. ESL students do not know when to double it and when not to. In students’ essays, I often see spelling mistakes like this: “planing” for “plan,” “rainning” for ”rain,” “writting” for “write,”  ”enjoyying” for “enjoy,” “studing” for “study,” “prefering” for “prefer,” and “offerring” for “offer.” These mistakes show that the students have not fully understood the grammatical rules used here.

Actually, the rule is not simple. We often give our students an incomplete rule. Here are a few things we need to do. First we should help students understand SYLLABLES. They need to be able to make a distinction between one-syllable verbs and two-syllable verbs. If a one-syllable verb ends with a single vowel letter + a single consonant letter, then we need to double the consonant letter before adding “-ing”. For example, “hitting”, but “eating”. We do not double “t” in “eating” because there are two vowel letters. For two-syllable verbs, what makes the difference is the stress. If the stress is on the first syllable, we’ll never double the last consonant letter; if the stress is on the second syllable, then we need to follow the rules to double or not to double the last consonant letter. That is why it is “referring”, but “offering”.  -Ron Lee

If you ask ESL students which is correct — “an university” or “a university”, many students will say “an university” is correct because “u” is a vowel. This kind of mistake occurs because we did not make the rules clear to our students, who know that there are five vowel letters “a, e, i, o, u.” They believe that if a noun starts with a vowel letter, we should use “an.” Actually the rule is that if a word starts with a vowel sound, we have to use “an.” That is why we say “an SUV,” even though “S” is a consonant letter. “U” is pronounced in two ways. “a uniform,” but “an uncle,” We say “a hotel,” but “an hour” because in “hour” h is not voiced.

The article “the” is the most frequently used word in English (“a/an” is the fifth).  Therefore, we often assume that it should not be a problem to our students. Actually, articles are very difficult to learn for ESL students because in their own languages, they might not have “articles”.

For the definite article “the”,  ESL students want to be told when “the” is used and when “the” is not to be used. Here a list I gave my students.

Where ”the” needs to be used:

1. To refer to something that has already been mentioned;

e.g. There is a watch on the table. The watch belongs to our teacher.

2. When both the speaker and listener know what is being talked about;

e.g.  Remember to turn off the TV;

3. Something that is unique;

e.g. the sun, the moon.

4. Directions;

e.g. in the east, in the south

5. Before superlatives;

e.g. the busiest day

6. Before ordinal numbers;

e.g. the first, the second, for the first time

7. With adjectives to mean a group of people;

e.g. the rich, the old

8. With names of oceans, rivers, and mountains;

e.g. the Atlantic Ocean, the Red Sea, the Amazon

9. With names of countries;

e.g. the United States, the People’s Republic of China (What we need to explain here is that “the” is used when the name of the country is composed of general English words. If the name is a proper noun which only means that country, we cannot put “the” before it. e.g. Brazil. We cannot say the Brazil.)

Readers are welcome to add more to the list.
