The next thing that's very important is the vocabulary you use.
Remember, you're getting marked on four different things. One of these things is vocabulary.
How do you improve your vocabulary mark?
Well, don't use simple, easy, boring, low-level words like,
"I like basketball because it's good. I don't like soccer because it's bad."
These words, "bad, good ", they're too easy.
You need to try to find vocabulary that is higher level and practice before you do the IELTS.
For example, a good thing to do is look at the list of topics you will probably be asked about.
Food is a very common thing they will ask you about.
Try to come up with vocabulary in advance and practice this vocabulary about the different topics.
For example, I know they may ask me a question about food.
I might learn some words that have to do with food.
Maybe I don't know the word "cuisine".
Well, if they ask me a question about food, I can say, "My favorite type of food -- I love Indian cuisine."
And there you go. They've just noticed you used a higher level word.
Same with friends.
A common word we use when we talk about friends, we talk about "acquaintances".
This is another good word to use.
Again, try to come up with vocabulary for each of the different topics, and practice.
Now, in this part of the IELTS, the examiner may ask you about what you like.
"Do you like to play sports? What hobbies do you like? What are your favorite foods?"
Now, one thing a lot of students do is they overuse "I like". "I like this. I like that. I like this. I like that."
This is not going to help you with your vocabulary mark.
Instead of using "I like" a lot, try something different.
与其过度使用 I like，不如试试不同的表达。
"I enjoy playing basketball. I enjoy hanging out with my friends.
I really love yoga. I really love bowling." "I prefer playing sports to doing other activities."
"I enjoy, I really love, I prefer"
-- I'm sure you can come up with more, but it's good to practice these types of expressions before you do the IELTS."
