2005年的诺贝尔化学奖颁给在烯烃复分解反应研究方面做出突出贡献的化学家。烯烃复分解是指在催化条件下实现C=C双键断裂两边基团换位的反应。如图表示两个丙烯分子进行烯烃换位，生成两个新的烯烃分子：2—丁烯和乙烯。

现以丙烯为原料，可以分别合成重要的化工原料I和G，I和G在不同条件下反应可生成多种化工产品，如环酯J；

（1）G的结构简式：______________ ；
（2）反应②的化学方程式是___________________________________________ ；
（3）反应④中C与HCl气体在一定条件只发生加成反应，反应④和⑤不能调换的原因是___________________________________，E的结构简式：_____________ ；
（4）反应⑨的化学方程式：___________________________________________ 。

（1） My father was an ill-humored man．I knew he loved me and his love was deep．He just didn’t know how to 36 it.
One evening we went out for a night on the town．We were sitting in an elegant restaurant that had a small but lively 37 ．When it played a familiar waltz tune I decided to 38 him for a dance.
“Dad, you know I’ve never 39 with you before．I begged you but you 40 wanted to．How about right now?”
I waited for the 41 refusal．But instead, he considered thoughtfully and then said, “Let’s hit the floor and I’ll 42 you just what kind of moves an old guy like me can still make.”
My father took me in his 43 and I felt overcome by emotion.
As we danced I looked up at my father carefully but he 44 my eyes.
“Dad,” I finally 45 , tears in my eyes, “Why is it so hard for you to look at me?” At last his eyes dropped to my face．“ 46 I love you so much.” he whispered back．I was struck dumb by his 47 ．It wasn’t what I had thought．But it was of course exactly what I needed to 48 ．I had always known that he loved me．I just hadn’t understood that his vast emotion had 49 him and made him silent．“I love you too, Dad!” I whispered back softly．He stumbled （结结巴巴地说） over the next few words: “I’m s orry that I’m not open．It’s 50 for me, but just remember how much I love you.”
When the dance ended I excused myself to the ladies’ room and during my absence 51 changed．
When I came back, Dad sat in his chair 52 his body leaning forward, very pale．Everything was really too late．He was 53 ．
That night all I saw was his leaning body and pale face．But it’s a totally different scene that I 54 now．I remember him saying “I love you” and my saying it back．The three words 55 on forever long after we are gone．
