BE TO and BE SUPPOSED TO - EXPECTATIONS (Beklentiler)



EXPECTATIONS : BE TO and BE SUPPOSED TO
a)      "Be to" ve "be supposed to", bir tarifeye, programa göre olması gereken olayları ifade ederken kullanılır. 
"Be to", "be supposed to" ya göre daha güçlü bir ifade biçimidir.

The film is supposed to start at 11.30.

b)      "Be to" ve "be supposed to", birinin bir başkasından beklentilerini ifade ederken de kullanılır.

"Be supposed to", bu kullanımıyla "should" ile yakın bir anlama sahiptir. Ancak "be supposed to"da gereklilik daima dış bir etkenden kaynaklanmaktadır. "Should" da ise gereklilik kişinin kendisinden de kaynaklanabilir.

(Hava kararmadan eve gitmem gerekir.)

It is not very safe in our neighbourhood at that time and I feel afraid.                                                                                                                                                     (I consider that it is better to go home before It gets dark.)

"Be to" ise "must" ile yakın bir anlama sahiptir. Her ikisi de "be supposed to" ve "should" a re daha güçlü bir ifade biçimidir. "Be to", dış etkenlerden kaynaklanan bir zorunluluğu, "must" ise kişinin kendisinden kaynaklanan bir zorunluluğu ifade eder.
