Grammar Genius B - Unit 1

Hello. I'm Mark "The spark". And I'm very clever. In fact, I'm a genius. This is my lab. As you can see, I work here everyday. I always have such brilliant ideas. I'm Betty "The brain" and I help Mark in the lab. At the moment We're fixing this computer. Here Mark! Can you hold this for me? Betty, what are you doing? Not like this. Like this. Ohhhh..... Ooops! Sometimes I hate this job.
