Then, we're going to do a sentence with "however" where we show a complicating factor or something that, maybe,
shows that what we're talking about we're not so clear about.
And then, as an optional sentence, you can share your experience. And this can be altogether one paragraph.
You finish that. Then, you do the same thing, but you pick a different point, either an advantage or a disadvantage.
So let's have a look at the set phrases. You can just learn these set phrases to use in your essays.
"One of the reasons"... well, obviously, it won't be about studying abroad. You just change it to fit your question.
"One of the reasons"（......的原因之一），当然啦，考试不会是关于出国留学的题目，所以你们要根据题目来把内容换掉。
"One of the reasons to study abroad..." "The main advantage of studying abroad..."
"One of the reasons to study abroad..."（出国留学的原因之一......），"The main advantage of studying abroad..."（出国留学的主要好处......），
"A good reason to study in a foreign country is..."
"A good reason to study in a foreign country is..." （去国外读书的一个重要原因是......）。
So we just take one of the pros because these are all positive statements.
"One of the reasons to study abroad is so you can make friends with people from other countries."
"The main advantage of studying abroad is to challenge yourself."
"A good reason to study in a foreign country is to learn a foreign language."
Okay? Then, you've got the first part of your introduction written.
Then, you go on to elaborate, say a little bit more about it. This bit is more general.
So let's imagine we're writing this point about making friends.
"When one studies in a foreign country, it is possible to make friends from different countries, which can be interesting."
