说到地震，人们为了保证安全应该怎么做？分析结构：此句是含时间状语从句的特殊疑问句，结构为“时间状语从句(Whenitcomesto+名词/动名词)，特殊疑问句(特殊疑问词what+情态动词+主语+谓语+其他)？”。Whenitcomesto...是固定句型，意为“当提到……时；说到……时”，用于引出话题，后接名词、代词或动名词(v.-ing)。类似表达：talkingof...(谈到……)、speakingof...(说起……)。e.g.Whenitcomestomath,howdoyousolvedifficultproblems?说到数学，你如何解决难题？Whenitcomestoreading,shealwayssharesinterestingbookswithclassmates.说到阅读，她总是和同学们分享有趣的书籍。3.Ifanearthquakehappens,weshouldstaycalmandquicklyfindsheltertoprotectourselvesfromfallingobjects.protectsb.from...保护某人免受……的伤害e.g.Parentsoftentrytoprotecttheirchildrenfromonlinedangers.父母常试图保护孩子免受网络危险。4.Fortyphoons,weshouldstayindoors,awayfromwindows.长难句分析：该句为简单句。Fortyphoons为介词短语作状语；主语是we；谓语是shouldstay；indoors为地点副词作状语；短语awayfromwindows作状语，用于补充说明stay的状态要求。5.Weshouldshutallwindowsanddoors.shut一词多义：(1)作动词时，shut可表示“关闭；(使)关门”，过去式和过去分词均为shut。(2)作形容词时，shut常用于“beshut”结构，表示“关闭；停业”。常见搭配：(1)shutthedoor/window关上门/窗(2)shutdown(使)(系统、大型设备)停止运转；(机构、企业)关闭(3)shutoff切断煤气(或水等)的供应；停止供应煤气(或水等)；关闭机器e.g.Remembertoshutthewindowbeforeyouleavetheroom.离开房间前记得关上窗户。Thestoreshutsat9p.m.everyday.这家商店每天晚上9点关门。Therestauranthasbeenshutforrenovationssincelastweek.这家餐厅从上周起停业装修了。6.Ifthereisawildfirenearby,weshouldfollowwhatauthoritiesadviseandleaveifnecessary.长难句分析：该句为复合句。Ifthereisawildfirenearby为条件状语从句；主句中，we是主语，shoulddo和(should)leave为并列谓语，由and连接；whatauthoritiesadvise作follow的宾语；ifnecessary为省略的条件状语从句，完整形式为ifitisnecessary，补充说明leave的前提条件。adv
