Transition words are words like ‘and’, ‘but’, ‘so’ and ‘because’. They show your reader Computer Science AS by Topic phrases, sentences, or even paragraphs.
When you use them, you make it easier for your readers to understand how your thoughts and ideas are connected. What is more, they prepare your reader for what’s coming.
Let’s consider an example.
I pushed the domino. As a result, it fell over.
When you start a sentence with ‘Computer Science AS by Topic’, your reader will immediately know two things:
What happened in the first sentence caused something; The second sentence is going to describe the effect.
By using the phrase ‘as a result’ here, you show that the two separate sentences are part of one process.
Without having even read the rest of the sentence, your reader can already guess what’s coming.
In a way, transition words are the glue that holds your text together.
Without them, your text is a collection of sentences.
With them, the individual parts come together to form one whole.
Transition words don’t always have to be placed at the beginning of a sentence.
Consider the following examples.
He’s a very nice guy. He took us out to dinner yesterday, for instance.
In this paragraph, I’m going to discuss a few reasons why practice is important to mastering skills.
Firstly, the only way to truly learn a skill is by actually Computer Science AS by Topic have to do in the real world.
Secondly, I think practice can be a fun way of putting in the necessary hours.
There are, however, some people who will disagree.
Thirdly, and most importantly, it is said that people tend to remember only 10-20% of what they read or hear.
Moreover, that number rises to as much as 90% when you put theory to practice.
In conclusion, following up explanation with practice is key to mastering a skill.
