作為一個小六學生, 你已經做得好好! 加油!樓上的朋友, 人地份功課係要用used to 來做句,你做咩事減哂人地d "used to" 呀?小心睇題目

chanhapi,
"to 後面[永遠]都係bare infinitives，即係個字唔洗轉 " <- not true
just give you two examples
1. I am used to having .....
2. I look forward to hearing you.....
You have to distinguish whether [to] is used as a preposition or an idiom.

In this case, [used to] is an example of idioms.
____________________________________________--

Used to
[USED TO] + [verb]

EXAMPLES:
I used to go to the beach everyday.

USE 1 Habit in the Past

"Used to" expresses the idea that something was an old habit that stopped in the past. It says that something was often repeated in the past, but it is not usually done now.

EXAMPLES:

Jerry used to study English.

Sam and Mary used to go to Mexico in the summer.

I used to start work at 9 o'clock.

Christine used to eat meat, but now she is a vegetarian.


USE 2 Past Fact

"Used to" can also be used to talk about past facts or generalizations which are no longer true.

EXAMPLES:

I used to live in Paris.

Sarah used to be fat, but now she is thin.

George used to be the best student in class, but now Leena is the best.

Oranges used to cost very little in Florida, but now they are quite expensive.
