(B)
“We are reading the first verse of the first chapter of a book whose pages are infinite...”
I do not know who wrote those words，but I have always liked them as a reminder that the future can be anything we want to make it.We can take the__28__，hazy future and carve it out of anything that we can imagine，just like a sculptor carves a statue from a__29__stone.
We are all in the position of the__30__.If we plant a good seed，we will reap a good harvest.If our seed is poor and full of weeds，we will reap a__31__crop.If we plant nothing at all，we will harvest nothing at all.
I want the future to be better than the past.I don't want it contaminated(玷污)by the mistakes and errors with which history is filled.We should all be__32__about the future because that is where we will spend the remainder of our lives.
The past is gone and static.Nothing we can do will__33__it.The future is before us and dynamic.Everything we do will affect it.Each day will bring with it__34__frontiers，in our homes and in our businesses，if we only recognize__35__.We are just at the beginning of the progress in every field of human endeavor.
28.A.real B.certain C.serious D.mysterious
解析 从该空后面的hazy可知将来是不可知的、神秘的。mysterious神秘的，符合语境。serious严重的，严肃的;certain确实，确定。
答案 D
29.A.shapeless B.useless C.worthless D.stainless
解析 雕塑家在雕刻之前用的石块应该是“不成形的”，故shapeless“无定形的，不成形的”符合语境。worthless“没用的，无价值的”;stainless“无污点的，无瑕疵的”;useless“无用的，无价值的”。
答案 A
30.A.sculptor B.farmer C.teacher D.doctor
解析 从下文的描述可以看出这里选B。
答案 B
31.A.bad B.useful C.wonderful D.good
解析 从上文中的“If our seed is poor and full of weeds”可以推断出不好的种子长不成好庄稼，故A项符合语境。bad crop意为“歉收”。
答案 A
32.A.worried B.curious C.anxious D.concerned
解析 既然不想让将来被错误所玷污，我们就应该关注将来。be concerned about“关注”，符合语境。故D项正确。答案 D
33.A.make B.keep C.change D.have
解析 从上一句可以知道，过去一去不复返，因此我们无法改变过去，故用change。
答案 C
34.A.new B.old C.gone D.away
解析 和本段开头进行对比：过去一去不复返，而将来的一切还未到来，也就是将来的一切都是新的，不为我们所知，故A项正确。
答案 A
35.A.it B.them C.that D.this
解析 根据句意可以看出这里的代词是指代前面的frontiers，因此应该用them。
答案 B
