Activity 4 Convert the following short conversations into reported speeches. One time, my elder brother and I had a chance to watch a late- night movie about the possibility of the computer taking over man's tasks. "I'm afraid that these computers will really take over all our tasks," I said. "Computers cannot replace us, even though they are taking over some of the tasks that were once accomplished by our brain," my brother replied. "Yes, I learned that our brain has more than 10 billion cells while the computer has only a few hundred parts," I agreed. "Therefore, our brain is far more complex than a computer," my brother explained. "How we use it is for us, not the computer, to decide."​
