2.whether/ifthat

不充当句子成分，无语义，只起连接作用，不能省略。Whether

whether/ifThatHubbleisbasedinspaceallowsittoseefurtherthanground-basedtelescopes.whether不做成分，表意思“是否”。从属连词:

that/whether/if

主语从句中用whether不用if的情况：1.主语从句位于句首时;

2.从句后有or或紧跟ornot时。1.__________he'llcomethiseveningisuncertain.2.It’suncertain_________he’llcomethisevening.3.__________she’scomingornotdoesn’tmattertoomuch.Whetherwhether/ifWhether宾语从句中

it

作形式主语放句首,从句为真正的主语，放在句末，使句子更平衡。1.It+be+形容词

+that从句常用句型clear,obvious,necessary,possible,likely,...Itisclearthatthegirltoldalie.2.It+be+名词词组

isapitythathemissedsuchaninterestingfilm.3.It+be+过去分词

原因状语用why；方式状语用how。如什么都不缺用that，Whether表“是否”。做题原则B1Circlethemistakesandcorrectthemintheblanks.1Thespacemissionwentsowellwasbeyondourexpectations.谓主Thatthespacemissionwentsowellwasbeyondourexpectations.Applyingtherules

主从为陈述句，不缺成分，不缺意义，用that来引导2Whethertheyareabletogrowmorevegetablesdependonhowmuchtimeittakes.谓主单个从句做主语，主句谓语用三单。Whethertheyareabletogrowmorevegetablesdependsonhowmuchtimeittakes.3Itwasnotclearhowlonghewillstayonthespacestation.主从句时态应与主句保持一致Itis
