句子分類回顧：根據(jù)類型句子可分為四種：簡單句、并列句、復(fù)合句、并列復(fù)合句。

　　 B:六類從句句型歸納總結(jié)
　　從句是相對于主句而言的，即它是從屬于某一個主句，而不能單獨作一個句子。在英語中，主要有三大從句，即名詞性從句(包括主語從句，賓語從句，表語從句，同位語從句)、形容詞性從句(即定語從句)、副詞性從句(即狀語從句,包括時間、條件、結(jié)果、目的、原因、讓步、地點、方式和比較九種。)
　　 (1) 形式主語從句句型
　　形式主語從句是寫作中非常常用的一種從句。我們先來看一下它是如何構(gòu)成的。(That+一個完整的句子可做主語)。比如說：(That education is important ) is clear.這就是主語從句的基本形式。但如果句子要是這樣，主語過長。所以，我們習(xí)慣于用it來代替原來的主語。而把原來的主語放在句子的最后。這句話可改為：It is clear that education is important.這就叫做形式主語從句。

　　 2It is a fact that
