Conditional Sentences (Kalimat Bersyarat Atau Pengandaian)

Conditional sentences merupakan kalimat bersyarat atau kalimat pengandaian. Kalimat bersyarat atau pengandaian biasanya sanggup diungkapkan dengan menggunakan klausa “if” atau “jika”.

Suatu kalimat bersyarat berisikan dua klausa yakni klausa utama (main clause) dan klausa syarat (if clause or conditional clause). Suatu klausa utama cuma akan bernilai benar atau tercapai jikalau klausa syarat sudah terpenuhi.

Selanjutnya , kita sanggup memukau suatu kesimpulan menurut kalimat bersyarat yang digunakan. Dalam penulisannya , kita sanggup menaruh klausa utama di permulaan atau di simpulan kalimat.

Dalam bahasa Inggris , ada tiga jenis atau tipe kalimat bersyarat yakni tipe 1 , tipe 2 , dan tipe 3 yang hendak kita dibahas lewat tabel dan diagram di bawah ini.

Seperti yang terlihat pada diagram di bawah , kalimat bersyarat (conditional sentences) berisikan tiga tipe yang memiliki abjad masing-masing yang berbeda.

Berikut disuguhkan tabel yang menyediakan ciri-ciri dari masing-masing tipe kalimat bersyarat beserta kesimpulannya (meaning).

If clause	Main Clause	Meaning
I. If Simple Present S + V1-s/es S + is/am/are	Simple Future S + will/shall + inf S + will/shall be	Masih mungkin terjadi. Maybe , Perhaps , Probably , Possibly.
Example : If I have much money , I will buy those motorcycles.		Maybe I have much money and buy those motorcycles.
II. If Simple Past S + V2 S + were	Past Future S + would/should + inf S + would/should + be	Simple Present S + V1-s ,es/ is ,am ,are Berlawanan dengan kalimat
Example : I would have the computer if the price were cheaper.		I don’t have the computer. The price is not cheaper.
III. If Past Perfect S + had + V3 S + had + been	Past Future Perfect S + would/should + have +V3 S + would/should + have + been	Simple Past S + V2/was/were Berlawanan dengan kalimat
Example : If She had stayed with me last night , She wouldn’t have been so lonely.		She stayed with another man. She was lonely.

Note !:
Pada tipe 2 , untuk if clause tidak dipakai tobe “was”. Apapun subjeknya baik itu jamak maupun tunggal , dipakai “were”. Sedangkan , pada kesimpulan atau arti (meaning) tetap dipakai “was” dan “were”.

Penggunaan :

Type 1
Digunakan untuk membicarakan suatu kemungkinan yang belum terjadi sehingga masih ada kemungkinan akan terjadi. Type 1 juga sanggup dipakai untuk menyatakan fakta umum. Ketik mengatakan ihwal fakta lazim , biasanya dipakai main clause dalam bentuk simple present juga. Kita juga sanggup menggunakan conditional tipe 1 dengan kalimat perintah menyerupai teladan pada nomor tiga di bawah ini.
Example :
- If the weather is fine , we will go out for a walk (menyatakan suatu kemungkinan).
- If the sum of the digits of a number is divisible by three ,the number is divisible by three (Fakta).
- If you meet my brother , please tell him that I need to talk to him (menyatakan perintah).
Type 2
Digunakan untuk membicarakan ihwal insiden kini (present) yang bertentangan dengan kalimat pengandaiannya. Dengan kata lain , kalimat pengandain tersebut berarti atau kesimpulan yang berlawanan.
Example :
- If I became president , I would change the social security system (meaning : I don’t become president).
- If Lia were ready , She would be much more confident (meaning : Lia is not ready , so she is not confident).
Type 3
Digunakan untuk membicarakan insiden atau kondisi lampau (past) yang bertentangan dengan kalimat pengandaiannya.
Example :
- If he hadn’t been careless , his car wouldn’t have hit that tree (meaning : he was careless and his car hit the tree).
- If you had warned me , I would not have told your father about that party (meaning : you didn’t warn me , so I told your father).

III. If Past Perfect S + had + V3 S + had + been	Had + S + V3 Had + S + been	Simple Past S + V2/was/were Berlawanan dengan kalimat
