Tetapi ada perbedaan antara keduanya yakni kita sanggup menggunakan “used to + infinitive” untuk menyampaikan sebuah pernyataan di periode lampau yang tidak lagi berlaku akan namun kita tidak sanggup menggunakan “would + infinitive” untuk mengungkapkan pernyataan itu.
Misalnya , untuk menyampaikan “dia dahulu mempunyai rambut panjang” maka sebutan yang paling sesuai digunakan merupakan “She used to have long hair” bukan “She would have long hair”.
Used to + Infinitive
Example :
- (+) She used to wake up early. (but now she doesn’t wake up early)
(-) She didn’t use to wake up early.
(?) Did she use to wake up early? - (+) He used to eat cereal for breakfast.
(-) He didn’t use to eat cereal for breakfast.
(?) Did he use to eat cereal for breakfast? - (+) Your brother used to go to the movies.
(-) Your brother didn’t use to go to the movies.
(?) Did your brother use to go to the movies? - (+) My mother used to have long hair.
(-) My mother didn’t use to have long hair.
(?) Did my mother use to have long hair? - (+) I used to see my grandmother on monday.
(-) I didn’t use to see my grandmother on monday.
(?) Did I use to see my grandmother on monday?
Ingat :
Pada kalimat negatif dan interrogatif , “used to” berganti jadi “use to”.
Be Used to + Verb-ing
Ungkapan ini digunakan untuk mengungkapkan sesuatu acara yang kita telah sudah biasa melakukannya.
Example :
- (+) I am used to going to my school on foot , it is not too far for me.
(-) I am not used to going to my school on foot , it is too far for me.
(?) Are you used to going to your school on foot? - (+) He is used to sleeping late at night , so he doesn’t mind doing it.
(-) He isn’t used to sleeping late at night , so he gets hard doing it.
(?) Is he used to sleeping late at night?
Pada kalimat negatif dan interrogative , “used to” tidak berubah.
Would + Infinitive
Example :
- (+) When he was a student , he would go to library on friday.
(-) When he was a student , he wouldn’t go to library on friday.
(?) When he was a student , Would he go to library on friday? - (+) When my brother lived in Jakarta , he would send me a book twice a month.
(-) When my brother lived in Jakarta , he wouldn’t send me a book twice a month.
(?) Would He send me a book twice a month?
Note :
Ungkapan “would + infinitive” biasanya digunakan untuk menceritakan acara di periode lampau akan namun jarang digunakan untuk mengungkapkan sebuah pernyataan menyerupai :
They would live in Medan.
I would have long hair.
She would get a flat nose.
