歸納總結(jié)：
★主語從句必須有引導(dǎo)詞；主語從句用陳述句語氣。
★連詞位于句首不能省略
★主語從句大多數(shù)情況下視為第三人稱單數(shù)，但也有例外.
★主語從句引導(dǎo)詞的選擇主要是根據(jù)從句的結(jié)構(gòu)和意義來選擇。
如果從句的意義和結(jié)構(gòu)完整，則用that。
如果從句的意義和結(jié)構(gòu)不完整，則根據(jù)從句的意義和結(jié)構(gòu)選擇相應(yīng)的引導(dǎo)詞。

that 和what 的選用：that 和 what 都可引導(dǎo)主語從句。但是，what除起連接作用外，還在主語從句中充當(dāng)成分，可做從句的主語、賓語、或表語，相當(dāng)于the thing(s) that；而that在主語從句中不充當(dāng)任何成分，只起連接作用。
