第一， 狀語從句。

　　在寫作當(dāng)中運(yùn)用的最多的是以下五種狀語從句，即原因狀語從句，讓步狀語從句，條件狀語從句，時間狀語從句和目的狀語從句。

　　Eg: Nonetheless, I am still in favor of space travel, for its merits far outweigh demerits.

　　盡管如此，我還是贊成太空探險，因為它的好處遠(yuǎn)遠(yuǎn)大于壞處。

　　2. 讓步狀語從句：常由although, though, even though/ if, as long as和notwithstanding引導(dǎo)

　　Eg: Although this view is wildly held, this is little evidence that education can be obtained at any age and at any place.

　　盡管這一觀點被廣泛接受，很少有證據(jù)表明教育能夠在任何地點、任何年齡進(jìn)行。

　　3. 條件狀語從句：常由if, on the condition that和providing that引導(dǎo)

　　第二， 定語從句。

　　這應(yīng)該算是寫作中最常用的一種句型之一。適當(dāng)?shù)剡\(yùn)用定語從句可以給你的文章增色不少。

　　例如，下面的這兩個句子用上定語從句馬上就變成了一個漂亮的復(fù)雜句。

　　第十，插入語。

　　一種獨立成分,與句子的其它成分一般沒有語法上的關(guān)系,大都是對一句話作一些附加說明或解釋。它通常由一個詞、一個短語或一個句子構(gòu)成,位置較為靈活,可置于句首、句中或句末,一般用逗號或破折號與句子隔開。
