Fill in the Blanks Verb to beOnline version The Greek sea god, Proteus, was (like the sea) capable of changing form in an instant. In order to get any decent information out of him, you had to grab him and hold on tight while he went through his various forms — lion, wild boar, snake, tree, running stream — it wasn't easy. The verb “To be” is said to be the most protean of the English language, constantly changing form, sometimes without much of a discernible pattern. Considering that we use it so often, it is really too bad that the verb “To be” has to be the most irregular, slippery verb in the language. by Marisol Arias Muñoz 1 _am___ _are___ _am___ __are__ __is__ _is_ __is_ __are__ _are___ __is_ 1 Susan my new friend . 2 I a very good driver . 3 My neighbours very noisy . 4 Your black cat in the garden . 5 Susan and Mike my parents . 6 They my best friends . 7 I sure . 8 Your best friend at home . 9 We from Spain . 10 Luke and Tom actors .
