两年前，我在一场车祸中失去了右手，此后我开始封闭自我，认为自己再也无法过正常的生活了。我装了一只假手，但它感觉不像是我的一部分。即使是像穿衣服这样简单的事情也难以置信地困难。然而，三个月前，当我有机会测试一只新的机械手时，一切都改变了。

canmovemyindividualfingersandholdontosmallthingslikepensandpencils.Moreamazingly,myrobotichandiscapableoffeelingvaryingdegreesofpressure,justlikearealhand.Inaddition,itlooksverylifelikewithspecialrubberusedontheoutside.

近年来，科学家们在机器人技术方面取得了很大的进步，他们在机械肢体方面的工作确实改变了我的生活。用我的新手，我可以移动我的手指，握住像钢笔和铅笔这样的小东西。更神奇的是，我的机械手能够感受到不同程度的压力，就像一只真正的手一样。此外，它的外表使用了特殊的橡胶，看起来非常逼真。

在过去的三个月里，我一直在测试我用这只新手所能做的事情的极限，它不断地给我带来惊喜。我重新发现了事故前喜欢的爱好。例如，自从我有了新的手，我又开始为我的家人做饭了。我不仅可以做得更多，而且我也变得更加自信和外向。我很感激我的机械手带来的所有新可能性。1.I__________________(reflect)onthearticleIreadaboutancientmedicineallday.2.I_________________(wait)fortwohourstoseethedoctorbutitisstillnotmyturnyet.3.Mymother________________(write)areportonthenewtreatmentallmorning.4.Thecompany________________(make)herbalmedicinesformorethan100years.5.Scientists________________(do)researchonthediseasesinceitwasfirstdiscoveredintheearly20thcentury.havebeenreflectinghavebeenwaitinghasbeenwritinghasbeenmakinghavebeendoingApplyingtherulesP35B1It(1)
