【考點(diǎn)】科教類閱讀．

【分析】本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了正如諺語(yǔ)人往高處走，水往低處流所說，虛擬水從山上到流經(jīng)河流到人類的消費(fèi)所經(jīng)歷的旅程，是如此的漫長(zhǎng)，許多缺水國(guó)家的虛擬水甚至基本都來自于其他國(guó)家，它真正做到了環(huán)球旅行．

【解答】25．C．推理判斷題．文章主要在講正如"人往高處走，水往低處流"，而現(xiàn)實(shí)生活中缺水國(guó)家的水基本都來自于其他國(guó)家，因此可推測(cè)As the proverb goes是正如諺語(yǔ)所說的意思，因此proverb介紹了這篇文章的主題；故選C．

26．C．細(xì)節(jié)理解題．根據(jù)文章最后一段"dry countries like Israel and Kuwait，both in the Middle East，get the majority of their virtual water from other countries"和"like the Netherlands and the United Kingdom，also get the majority of their virtual water from other places"可知色列，科威特，中東國(guó)家，荷蘭，英國(guó)等國(guó)大部分虛擬水都來自其它地區(qū)；故選C．

27．D．主旨大意題．通讀全文，可知文章主要在講虛擬水從山上到流經(jīng)河流到人類的消費(fèi)所經(jīng)歷的旅程，有時(shí)它們甚至經(jīng)歷了許多國(guó)家，因此可知最合適的標(biāo)題是"水的環(huán)球旅行"；故選D．

28．A．推理判斷題．根據(jù)文章，可知文章主要在講虛擬水從山上到流經(jīng)河流到人類的消費(fèi)所經(jīng)歷的旅程，有時(shí)它們甚至經(jīng)歷了許多國(guó)家，文章運(yùn)用了舉例的手法給出了許多具體的事實(shí)，比如缺水的國(guó)家等，因此這是一篇科技類說明文，它一般會(huì)發(fā)表在科技新聞報(bào)道上；故選A． 

29．Though many Internet celebrities try to shrug off their fame，Yan Mingliang，27，has dreamed of joining the Internet elite（精英） ever since he entered college．

However，luck didn't favor him．Instead，fame fell into the lap of his pet dog，Beiji．In early 2015，Yan used his microblog to post two pictures of Beiji lying on the ground，and they went viral on social media．Because he took the photos at a strange angle，it almost looks like Beiji's body has fallen apart．

Finally，Yan got to experience what is like to be an Internet celebrity，or more accurately，the owner of an Internet celebrity dog．New followers started to flood in，and Yan received hundreds of private messages each day．In less than four weeks，Yan managed to attract more than 20，000followers．"I am famous now．"Yan thought at that time．

However，fame didn't just bring joy，but also annoyance．Since Beiji was only 3months old and Yan sometimes had to put him into a cage as a means of"education"，there were also private messages from followers who fiercely criticized Yan for being too cruel．

"It gradually occurred to me that no matter how frankly you present yourself on social media，Internet users only witness part of your life．And their judgments depend on that partial life story of yours，"said Yan，"They don't know how hard it is to raise a pet dog when you're unemployed，Yan explained．They also don't care about whether the dog they're enjoying is being pushed too hard．"

Yan finally decided to leave his Internet fame behind and focus more on his real life．"The lesson I learned is that，if you can't live up to your followers'expectations，it's better not to be an Internet celebrity，"he said．
