2.whether/ifthat

不充當(dāng)句子成分，無語義，只起連接作用，不能省略。Whether

it

作形式主語放句首,從句為真正的主語，放在句末，使句子更平衡。1.It+be+形容詞

原因狀語用why；方式狀語用how。如什么都不缺用that，Whether表“是否”。做題原則B1Circlethemistakesandcorrectthemintheblanks.1Thespacemissionwentsowellwasbeyondourexpectations.謂主Thatthespacemissionwentsowellwasbeyondourexpectations.Applyingtherules
