Hi Radha,
Do not worry, learning the English language is not difficult. Even people coming from a Tamil medium speak English well.
You can try out a few steps:
1. For an HR presentation, skills are very important. So, you can learn from "Young World" (THE HINDU) "Opportunities" where HR tips are well presented in sentences. While reading the sentences, pay attention to whether they are presented in the past tense or present tense, singular or plural. This is very important. By concentrating on this, you will be able to frame sentences and paragraphs easily.
2. While you watch CNN, IBM, BBC, focus on the accent but not exactly the way they speak because they are news readers. Concentrate more on novels and movies. By doing so, you will clearly understand the accent and the way they speak.
3. Learn a story in Tamil and its English translation (try to purchase a book with both versions). Understand the Tamil story and try to frame a sentence in English, then compare.
4. Daily, look up words in the dictionary for their meanings. While you listen to the television and read books, mark those words or write them on paper to revise daily and improve your verbal skills.
These are easy ways for you to improve your verbal communication and writing skills in a short period.
I have attached the communication handbook for you to review.
If any of your friends speak English well, ask them to speak with you so that you can improve.
Good luck, Radha!
Regards,
Kanchana
