阅读下列说明，回答问题1至问题3，将解答或相应的编号填入答题纸的对应栏内。【说明】某公司为当地一家书店开发图书资料垂直搜索引擎产品，双方详细约定了合同条款，包括合同金额、产品验收标准等。此项目是该公司独立承担的一个小型项目，项目经理小张兼任项目技术负责人。项目进行到设计阶段后，由于小张从未参与过垂直搜索引擎的产品开发，产品设计方案经过两次评审后仍未能通过。公司决定将小张从该项目组调离，由小李接任该项目的项目经理兼技术负责人。小李仔细查阅了小张组织撰写的项目范围说明书和产品设计方案后，进行了修改。小李将原定从头开发的方案修改为通过学习和重用开源代码来实现的方案。小李还相应地修改了小张组织编写的项目范围说明书，将其中按照项目生命周期分解得到的大型分级目录列表形式的WBS改为按照主要可交付物分解的树型结构图形式，减少了WBS的层次。小李提出的设计方案和项目范围说明书得到了项目干系人的认可，通过了评审。

小李修改了项目范围说明书，但原有的项目范围管理计划不需要变更。

阅读理解。

     We tried so hard to make things better for our kids that we made them worse. For my grandchildren, I'd know better. I'd really like for them to know about hand-me-down clothes and home-made ice cream and leftover meatloaf. I really would.

     My cherished boys, I hope you learn humility by surviving failure and that you learn to be honest even

when no one is looking. I hope you get a black eye fighting for something you believe in. I hope you have

to share a bedroom with your younger brother. And it is all right to draw a line down the middle of the

room, but when he wants to crawl under the covers with you because he's scared, I hope you'll let him.

And when you want to see a Disney movie and your kid brother wants to tag along, I hope you take him.

     I hope you have to walk uphill with your friends and that you live in a town where you can do it safely.

I hope you learn to dig in the dirt and read books, and when you learn to use computers, you also learn

how to add and subtract in your head.

     May you skin your knee climbing a mountain, burn your hand on the stove and stick your tongue on a

frozen flagpole (旗杆). I hope you get sick when someone blows smoke in your face. I don't care if you

try beer once, but I hope you won't like it.

     I sure hope you make time to sit on a porch with your grandpa or go fishing with your uncle.

     I hope your mother punishes you when you throw a baseball through a neighbor's window, and that

she hugs you and kisses you when you give her a plaster of pared mold of your hand.

     These things I wish for you-tough times and disappointment, hard work and happiness.
