题目内容
5．When you are searching for some information online，just as you ________ look at when a book was published，you must also check the dates of the websites，usually at the bottom of the webpage．（ ）| A． | must | B． | might | C． | can | D． | should |
分析 当你在网上搜查信息时，也许正如你看一本出版的书，你也必须核查通常位于网页底部的日期．
解答 答案是B．本题考查表示推测的情态动词；must在肯定句中表示"有客观依据的推断"，"肯定…"，本题中无肯定推测的客观依据，故排除；might可以用在肯定句和否定句中表示不太确定的推测"也许"，本题中表示在看出版的书的时候你"也许"会看书的出版日期，故B正确；can往往用在否定句和疑问句中表示推测，故排除；should表示"责任和义务"，不符合语境．
点评 要在正确理解情态动词的基本含义的基础上，整体理解语境中的情感态度，做出合理的判断．

20．Elephants in Uganda are starting to come close to villages near national parks．Sometimes，the big animals harm or even kill villagers．（36）ASo，the Uganda Wildlife Authority has been giving people new tools to keep the elephants away：vuvuzelas，which became very popular in the South Africa World Cup．They are plastic instruments some fans use at sports events to cheer for their teams．
（37）CWhen the elephants hear the unpleasant sound，they leave，and no one is harmed．

Another official for the Uganda Wildlife Authority，Gessa Simblicious，says one elephant-prevention solution will not work everywhere in Uganda．And one day，elephants may get used to the vuvuzela noise，just as they do the sound of the A-K47．（40）F
