8、eventy-one percent of its surface is covered by water.名詞性從句連接詞(一)that、whether和if1連接詞thatthat引導(dǎo)從句時，本身無意義，在從句中不充當(dāng)成分。但是that在引導(dǎo)主語從句、表語從句時，一般不能省略。例如：That he suddenly fell ill made us surprised.。The fact is that we are behind other groups.在引導(dǎo)賓語從句時，常被省略；但是以下兩種情況除外：(1)多個并列從句出現(xiàn)時，第一個that可以省略，其他的不能省略。She said
