✍️ Pratik Sorular
Soru 1: "Invention" ile "discovery" arasındaki fark nedir?
Invention yeni bir şey yaratmak (telefon, ampul), discovery ise zaten var olan bir şeyi bulmaktır (yerçekimi, penisilin).
Soru 2: "The telephone was invented by Bell." Bu cümle neden passive?
Çünkü cümlenin öznesi eylemi yapan değil, eylemden etkilenendir. "The telephone" (telefon) icat eden değil, icat edilen nesnedir. Yapı: was + V3 (invented).
Soru 3: Simple Past Passive nasıl kurulur?
was/were + V3 şeklinde kurulur. Tekil: was (The car was made), Çoğul: were (The books were written). "by" ile yapan belirtilir.
