Modal Auxiliary


Dalam bahasa Inggris kita sering menemui kata-kata untuk mengekspresikan sesuatu yakni modal.  Salah satu ciri khasnya adalah selalu diikuti oleh kata kerja bentuk pertama.  Kecuali pada kalimat pasif, maka diikuti oleh be+V3 atau past participle. Untuk lebih jelasnya bisa dibaca dalam ringkasan berikut ini.

Study the summary below.

The use and meaning of modals:

1.     can/could

a. Can and could are used to express ability. Could is the past form of can.

Example:

When I was a child I couldn’t take a bath alone, but now I can.

b.     Sometimes, could is used as a polite remark in a request.

Example:

Could you do me a favor? It is more polite than “Can you do me a favor?”

2.     may/might

a. Might, which is used to express permission, is the past form of may.

Example:

Sir, why may I not go home earlier now whereas yesterday I might do it?

b.     When may and might express possibility, both refer to either now or future time.

Their difference lies in the degree of probability; when we use might we refer to something less possible to happen, while may refer to a more probable thing to happen.

Example:

a.     She may come late because of the traffic jam.

b.     Even though she is a rich girl, she might not have money to buy a new car because she drives an old car.
