Unit 4, Present Tense was familiar and easiest unit to me untill i studied Unit 4. I have studied about present 4 tences in wider range and i can say completely understand this subject. it also helped me to find methods of how to teach effective to students. its evitable to get students to undertand fully the difference usage of these tences.The unit required much more careful reading that the other ones. One of the most difficult teaching subject was presented only on 22 pages of the unit text. All teachers will definitely need to use more resources to prepare for lessons on pronunciation. It was very useful to provide some examples of best resources on the page 22 of this unit.
