Common grammatical problems

Rule of thumb: You will usually use the present tense unless you are discussing examples or a situation in the past

1) One of the problems is

2) the media, the government, the Internet, the United States

3) in the past, there was

4) aid (help) vs Aids (disease)

5) Note the spelling of these words - sarcasm, argument, definitely, portray, athlete,
advertisement, enthusiastic, satisfied, perseverance, dependent

6) has taken, has seen, has become (use the participle form!)

7) Only singular (no 's'!) - equipment, research, proof, evidence

8) will come, shall see, can do (after 'will, shall, can, must', the word is in the basic form, no 's')

9) youth/youths? - Use 'young people'!

10) sport/sports? - Use whatever is given in the question! (sports refer to the different games)

11) (Especially for AEP students!) art/the arts - USUALLY, 'art' refers to painting & drawing, but in some cases, dance/poetry/music can also be seen as art. Look at the question, if it is too narrow to just look at drawing and painting, you should include the other forms of art as well
