将种子的结构与其功能用直线连接起来．

答案

种子具备了外界条件和自身条件后，开始萌发，首先吸水膨胀，种皮变软，呼吸作用逐渐增强，将储存在子叶或是胚乳中的营养物质逐步分解，转化为可以被细胞吸收利用的物质，输送到胚的胚轴、胚根和胚芽．在种子萌发初期，胚根生长最快，首先突破种皮向地生长，并发育成根．随后胚轴伸长，胚芽突破种皮背地生长，发育成茎和叶．通过这个过程，种子的胚就发育成了幼苗．

It was 20 years ago. I was driving home with my 4-year-old son. Traffic was light. I was singing quietly along       the song playing on the radio. I    at the intersection(交叉路口) and looked both ways. The road was      . I slowly started to make a right turn when suddenly a car rounded the curve at high speed and came      at me. I stomped (猛踩) on the brakes of my car killing the engine in the process. The speeder zoomed (疾驰) past my dead car     me by inches without even slowing down.
     I knew it, a stream of rude words was flying from my lips,      after the car and its driver. I then saw my son who was staring up at me     . With a red face and a(an)      smile I started the car, pulled back onto the road, and headed home.
Later that evening I was reading a book when I heard certain     words coming from my son’s bedroom. He was replaying the       over and over in his mind. Too          I realized the       of those words that had flown from my lips in that moment of    . It took a lot of talks about good language and bad language with my son to undo (消除)the      of that incident.
That     , however, did teach me just how strong words      be. It helped me to decide to stop swearing (咒骂) in my own life and to start using words uplifting and inspire instead. I slowly realized that language is a      from God and should be used to make our world better but not worse. I learned      that a few loving words can help a hurting heart, strengthen a       spirit, and lighten a heavy load. I pray then that all of your words today are full of love, joy, happiness, and light.
