Penjelasan

Kata kerja bantu Tobe (is,am,are) bisa digunakan dalam bentuk kalimat Positive, negative (Menyangkal) , ataupun Interrogative  (Pertanyaan), terutaama dalam kalimat Nominal (Nominal Senteces). Tobe juga digunakan dalam kalimat Present Continuous atau Past Continuous tense, seperti dalam kalimat;

She is watching TV now but last night she was reading her lessons until late in the night.

Kata kerja bantu Do dalam bentuk simple present tense bisa berubag menjadi Does jika subjectnya  Orang ketiga tunggal (She, He, it), dalam betuk Lampau (Past tense) do berubah manjadi Did untuk semua Subject, Do juga berfungsi sebagai kata kerja yang artinya”Melakukan” =”What did you do last week?”

Kata kerja setelah Modal adalah kata kerja pertama tanpa to (Bare infinitives) dan jika tida ada kata kerja maka “Be” sebagai penggantinya.
