一、涂色略。提示:三原色:根据原文中“Red, yellow and blue are primary colours.”可知三原色分别为 red(红色),yellow(黄色),blue(蓝色)。故答案分别涂红色、黄色和蓝色。
涂色略。提示:合成色:根据“Secondary colours are made by mixing two primary colours.”和“Red and blue make purple.”可知合成色是三原色两两混合而成,红色和蓝色混合可得到紫色,故红色和蓝色之间涂紫色。根据“Blue and yellow make green.”可知蓝色和黄色混合可得到绿色,故黄色和蓝色之间涂绿色。根据“Orange is also a secondary colour.”可知橙色也是合成色,故黄色和红色之间涂橙色。
二、1. F 句意:红色、黄色和绿色是三原色。根据“Red, yellow and blue are primary colours.”可知三原色为红色、黄色和蓝色。故答案为 F。
2. F 句意:我们可以混合绿色和黄色制成蓝色。根据“But we can't get primary colours by mixing other colours.”可知蓝色作为三原色是不能通过混合其他颜色制成的。故答案为 F。
3. T 句意:黄色和红色可以制成橙色。根据“Orange is also a secondary colour.”可知橙色也是合成色,三原色两两混合可制成合成色。黄蓝混色为绿色,蓝红混合为紫色,故推知黄红混合得到橙色。故答案为 T。
