Answer 1

分析 隨著越來越多的中國人在網絡上尋找健康和醫療信息，人們也更加擔心找到的是一些不正確或自相矛盾的建議．這是由于網絡上的健康信息缺少規范．一項由國家衛計委健康教育中心實施的調查表明，網絡已經成為人們尋找健康信息的主渠道，大約有三成接受調查的人說他們在看病之前都會在網絡上尋找自我診斷的建議．其中，作為中國最受歡迎的搜索引擎，百度陷入了這場爭論的中心．上個月，多個非政府組織對百度的商業化模式進行了調查．對此，百度承諾將停止與健康有關的商業論壇，并邀請非政府組織來管理相關論壇．

解答 1．may；考查情態動詞．句意表達的是不肯定的推測，也許，大概，要用may來表達．
2．because of/due to/owing to；考查介詞短語．句意表達的是原因，后接名詞，要用表示原因的介詞來表示．
3．surveyed；考查分詞．句中survey是作those的后置定語；survey與those構成動賓關系，要用表示被動的過去分詞來修飾．
4．consulting；考查動名詞．句中before是介詞，在…之前，后接名詞或動名詞，在句中作時間狀語．
5．itself；考查反身代詞．句中find+名詞或代詞+地點，表示發現某人或某物在某個地方；句意表達的是Baidu發現自己陷入了爭論的中心，要用指物的itself來表示．
6．an；考查冠詞．句意表達的是一項調查，要用不定冠詞來限定；investigation是元音開頭的單詞，不定冠詞要用an．
7．accusing；考查分詞．題干中有逗號分隔，沒有連詞，要用非謂語動詞；accuse與主語The NGOs構成主謂關系，要用主動；accusing sb of sth指控某人某事，在句中作伴隨狀語．
8．in which；考查連接．句中it promised to cease the commercialization of forums修飾statement，是一個定語從句；從句結構完整，要用關系副詞；先行詞statement表示抽象地點，即in the statement在聲明中．

點評 語法填空題是考查學生的語言運用能力．解題時，要在理解文章的基礎上，靈活運用語法知識，如詞性，時態，名詞單復數，連接詞，代詞，冠詞等判斷空白處應填寫的內容．答完后，還要通讀全文，核對所填單詞形式是否正確，是否符合語境．
