Dear native speakers. Please, assist me to compose an amount of sentences which describe a definite world. The world looks like this: 1. There is a red hard rough heavy box; 2. There is a green soft smooth light cube; 3. The box is bigger than the cube. Please, use the words from the list: Cube, green, soft, smooth, big, above, close, stand, fast, light, good; Box, red, hard, rough, small, under, far, move, slow, heavy, bad. Sentences can be of any length: from one word to 30 or more. Any suffix, prefix, conjunction, prepositions etc. can be used.
