当你使用这支笔的时候，你可以选择任何颜色来配合你的感受，这样你就可以更加专注记笔记。此外，不同的颜色可能会改变你的感受。一项研究表明，颜色对我们的大脑有很大的影响。例如，当你感到悲伤时，你可以选择蓝色来让你放松。如果你需要在不好的事情发生时冷静下来，绿色可以起作用。第三种颜色是黄色。它意味着充满活力和幸福。你一定想知道它有多少钱。只要20元。它很便宜。

我相信我的发明可以帮助你很多。它不仅可以配合你的感受，还可以安慰你，给你带来很多好处。;Samplewriting;1.Completethepassagewiththecorrectformsofthewordsinthebox.;2.Rewritethesesentencesusingthepassivevoice.;3.Findoutinformationaboutoneinventionandwritesentencesbelow.;
