Jawaban:

1. (+) Albert has to sleep

(?) Does Albert have to sleep?

2. (+) You have to go now

(-) You don't have to go now

Penjelasan:

(?) = Interrogative form, yaitu bentuk pertanyaan dari pernyataan. Struktur:

do/does + subject (I/you/we/they/dll.) + verb 1 (have to, dll.)+ remainder of sentence + ?

Contoh:

Do I have to attend the meeting?

Does she have to study now?

(-) Negative form, yaitu bentuk negatif (menambah kata not/-n't) dari positive form. Struktur:

subject (I/you/we/they/dll.) + do/does + not/-n't + verb 1 (have to, dll.) + remainder of sentence

Contoh:

I don't have to go to school today

She doesn't have to take care of him

(+) Positive form, yaitu bentuk positif (tanpa kata not/-n't). Untuk do/does tidak diperlukan. Struktur:

Subject (I/you/we/they/dll.) + verb 1 + s/es (jika subject he/she/nama orang) + remainder of sentence

Contoh:

You have to eat vegetables

He has to leave at 7
