Four Patterns to Learn
Notice the highlighted words in the notes and the underlined phrases in the examples.
happy / glad + to + action word
After words like happy, glad or ready, say to + action word. It tells what makes us feel happy or ready.
Keep the action word plain: never add -ing. Say "glad to help", not "glad to helping".
I am happy to earn a little extra money.
She was glad to help her brother with his chores.
It is hard / easy / wise + to + action word
Start with It is when you talk about doing something in general. Then say a word that shows how we feel about it: hard, easy, wise.
Then say to + action word. Say "It is hard to save". Do not say "It is hard for save".
It is hard to save when you see a nice game.
It is wise to put every penny in a safe jar.
Say who: for me, for Ben
To say who does it, put for + the person before to. Say for me, for Ben or for us.
Say for me, not "to me": "It is easy for me to spend", not "easy to me to spend".
It is easy for Ben to spend his weekly money.
It is smart for us to start a bank account early.
too big / too full + to + action word
too means more than we want, so we cannot do it. Put too before the describing word: too expensive, too full.
Then say to + action word. Do not add it at the end: say "too expensive to buy", not "too expensive to buy it".
The bag is too expensive to buy today.
This small envelope is too full to close properly.
Pattern to remember
"It is hard to save money, but it is important to put a little in the jar every week."
