Are you familiar with logic in English? Using logic well will help you convince people of your opinion and score more highly in speaking tests.
This is a quick guide to a common type known as deductive logic. That means we start with a major premise, add a minor premise, then draw a logical conclusion based on them.
Here is perhaps the most famous example:
Major premise: All humans are mortal.
Minor premise: Socrates is human.
Conclusion: Socrates is mortal.
You can also follow this line of reasoning for many other topics:
Major premise: Cities with good food are great to live in.
Minor premise: Portland has good food.
Conclusion: Therefore, Portland is a great city to live in.
It's useful to put aside the message and just think about it like math: A = B, and C = A, so C = B.
Put another way:
A) good food = B) great city, and
C) Portland = A) good food, so
C) Portland = B) great city.
This is simple, but a lot of students miss it when they are speaking. For instance:
My hometown is a great place to live.
There is a lot of really good food there.
That example is not a finished logical argument. It's missing a step.
Here is that argument, done logically:
[Claim] My hometown is a great place to live.
I think (A) good food makes for a (B) great place to live.
(C) My hometown has a lot of (A) really good food.
Therefore, (C) my hometown is a (B) great place to live.
Although that was a logical answer, it's a bit weird in spoken English. It needs detailed evidence. Here's the same logic with some detail, in spoken English. It still sounds a bit weird, but it's an improvement.
I'm from Portland, Oregon. It's a great place. First of all, when I think about places to live, good food is the most important. We eat every day, hopefully three times a day, and we should enjoy that time! Portland has the best food. There are so many great restaurants. The ingredients are local and fresh, and the flavors are a mix of different cultures, like Mexican, Chinese, American, and more. It's all done so well. You have to go and taste it for yourself. So, since good food makes for a good place, and Portland has the best food—obviously, it's a good place to live!
If you want to convince people of your opinion and get a high score in your next speaking test, then practice making your logic plain and clear.
Try it now. Here's a question to help you start:
What do you recommend visitors eat in your hometown?
Think about what is important for visitors. Think about what makes for good food. Then use deductive reasoning in your answer.
