And also, a lot of people use idioms because... yeah, idioms will get you extra points, but they're using them incorrectly or in the wrong context, again,
make sure you know the words you're using, make sure you know the idioms you're using, and shorter sentences can actually be better.
Simple is often better than complex.
If you think about... as an analogy, if you think about cooking, the more spices you put into the dish, the less you taste the actual meat or the actual core of the dish.
Simple is best.
Let me give you an example.
Here are two sentences, okay, let me read them to you.
"The CEO", Chief Executive Officer, like the head of the company...
"The CEO's tenure at the company was abbreviated due to his reluctance to integrate more females into upper managerial posts,
"The CEO's tenure at the company was abbreviated due to his reluctance to integrate more females into upper managerial posts, （首席执行官在公司的任期被缩短了，因为他不愿让更多的女性进入高层管理职位，）
thereby drawing the ire of the Board who consequently relieved him of his duties."
thereby drawing the ire of the Board who consequently relieved him of his duties."（因此惹怒了董事会，他们将他罢免了。）
Now, this sentence is perfectly okay.
It's grammatically correct, all the words are being used correctly, but if you can write a sentence like this the way that I wrote it here,
then you don't need to worry about the IELTS or the TOEFL; your English is obviously very high level.
If you can do this, then this test will be very easy for you.
However, a lot of people, a lot of test-takers try to write this sentence, and then they end up making many, many mistakes.
They don't use this word correctly: "abbreviated", they say: "abbreviation", okay, that's the more common thing of it, "abbreviated" means made shorter. Okay?
"Reluctance", hesitance, like not really wanting to.
This word: "ire", I write all the time, I write for a living, I never use this word "ire", because it's so old-fashioned.
And also, it's a small word, right, so you don't need many syllables, you don't need very rare words.
You need to be simple, you need to get your message across.
