18．There is an old Chinese proverb that states"One Generation plants the trees； another gets the shade，"and this is how it should be with mothers and daughters．The relationship between a mother and daughter is sometimes confusing．If close，the relationship can be similar to friendship．However，the mother and daughter relationship has unique characteristics that distinguish it from a friendship．These characteristics include a hierarchy （等級） of responsibility and unconditional love，which preclude mothers and daughters from being best friends．
Marina，27 years old，says，"I love spending time with my mom，but I wouldn't consider her my best friend．Best friends don't pay for your wedding．Best friends don't remind you how they carried you in their body and gave you life!Best friends don't tell you how wise they are because they have been alive at least 20 years longer than you．"This doesn't mean that the mother and daughter relationship can't be very close and satisfying．
While some adult relationships are still troubled，many find them to be extremely rewarding．This generation of mothers and adult daughters has a lot in common which increases the likelihood of shared companionship．Mothers and daughters have always shared the common experience of being homemakers，responsible for maintaining and passing on family values and traditions．Today contemporary mothers and daughters also share the experience of the workforce and technology，which may bring them even closer together．
Best friends may or may not continue to be best friends，but for better or worse，the mother and daughter relationship is permanent，even if for some unfortunate reason they aren't speaking．The mother and child relationship is closer than any other．There is not an equal relationship．Daughters should not feel responsible for their mother's emotional well-being．It isn't that they don't care deeply about their mothers．It's just that they shouldn't be burdened with their mother's well being．
The mother and daughter relationship is a relationship that is not replaceable by any other．Mothers never stop being mothers，which includes frequently wanting to protect their daughters and often feeling responsible for their happiness．Mother always"trumps"friend．

分析 本文論述了母女關系，認為母女關系獨具特點，不同于友誼，母親與女兒不可能成為最好的朋友．作者認為，母女之間有許多共同之處，母女關系永存、不可替代．而友誼是雙向的，但是母親永遠希望保護女兒、為女兒負責，女兒卻不必為母親的幸福承擔責任．
解答 36．B 詞義猜測題．根據第二段"Best friends don't pay for your wedding…Bestfriends don't tell you how wise they are…"可推斷，這里指母女之間不能成為最好的朋友，preclude意為"阻止"，preclude后面的from提示其含義應為prevent．故答案為B．
37．A 細節(jié)理解題．根據第三段…many find them to be extremely rewarding．Thisgeneration of mothers and adult daughters has a lot in common which increasesthe likelihood of shared companionship．說明母女之間的共同之處有助于增強相互關系的可能性，因而這是一種rewarding adult relationship．故答案為A．
38．C 主旨大意題．縱觀全文可知，本文論證的是母女關系不同于朋友關系但超越朋友關系．A，B兩項與文章主旨不符，D項與第二段I lovespending time with my mom 一句不符．故C項正確．
39．B 寫作方法題．問的是"論證方法"．本文采用的是"說理"的方法．故B項正確．A項"列數據"；C項"引名言"；D項"舉實例"．
40．D 主旨大意題．本文對比了母女之間的友誼和好朋友之間的友誼，認為母女不可能像最好的朋友，D項最能體現文章的主題，故答案為D．
點評 本文是科教類閱讀，主要考查細節(jié)理解題和推理判斷題．在做細節(jié)理解題時，首先根據題目要求迅速在文章里找出相應的段落、句子或短語．認真比較選項和文中細節(jié)的區(qū)別，在做推理判斷題時不要以個人的主觀想象代替文章的事實，要根據文章事實進行合乎邏輯的推理判斷．
