Today I’m going to introduce a special pen. This special pen was invented by Liu Jie. It has three colors and is used for taking notes quickly. It is very useful if you have a lot to write down. There is a microchip that can store a number of common words. When you are writing, you just need to write several letters with the pen, then press the button on the pen, finally the letters will change into the complete words. The microchip can contain up to 1000 words and you can make changes to them whenever you need to. I think this special pen is going to be popular among students. I’d like to introduce a new invention to you. It’s a cleaning dog which was invented by Alex. It was invented in 2017. It is used for dealing with rubbish at home. It looks like a real dog, but it is cleverer than a real dog. Also, you don’t need to feed is because it uses its nose to look for its food --- the rubbish. And the rubbish will turn into energy after being eaten. You must want to know how much it is. It’s 30 dollars. It’s a little expensive but you will find it very convenient to help with the housework. I think it will be widely used in the future. It is often difficult to decide on the inventor of certain inventions. This is because sometimes a few people may ________ things which are nearly the same. It’s hard to tell who came up with the idea first. invent, doubt, mention, website, all of sudden 1. Complete the passage with the correct forms of the words in the box. invent Some inventions can also lead to other inventions _____________. So some people _______ whether the inventor came up with the idea himself or herself. They think that the inventor used someone else’s idea to create his or her invention. That is why books or _________ usually _________ more than one inventor when giving information about inventions. all of a sudden doubt websites mention invent, doubt, mention, website, all of sudden 1. Someone stole my watch. _______________________________________________ 2. They used five eggs to make this big cake. _______________________________________________ 3. When did they invent the personal computer? _______________________________________________ 4. They asked us not to run in the hallway. _______________________________________________ 5. Someone took the video back to the store. _______________________________________________ My watch was stolen (by someone). When was the personal computer invented? Five eggs were used (by them) to make this big cake. 2. Rewrite these sentences using the passive voice. The video was taken back to the store (by someone). We were asked not to run in the hallway (by them). $
