2019年中考英語語法主要句式知識復習
在原因狀語從句中主要是
① because， 應譯為"因為"。它表達的因果關系最強，如： he didn't pass the exam because he didn't study hard
② since 應譯為"既然"，如： since you were ill yesterday i left some notes on your desk
③ as 應譯為"由于"，如： as it is too hot we'd better go swimming since 與 as 所表達的因果關系遠比 because 弱得多。而 for 表達的因果關系最弱。它不能用于句首，如： he studies hard, for he wants to go to college在比較狀語從句中有同級比較 as … as， 如： this book is as good as that one
要注意的有兩點：
① as … as 中間要用原級而不是比較級。
② 用形容詞還是副詞，如： mary writes as carefully as tom 而其否定句為 not as (so) … as， 如： they didn't work so hard as we did, 而不同級比較用比較級加 than, 如： he is younger than i am
要注意的是表示"越來越"這一概念時有兩個句型：
① 比較級＋and＋比較級，如： the days are getting longer and longer the little girl is becoming more and more beautiful
② 定冠詞 the ＋ 比較級＋ the ＋ 比較級，如： the harder you study, the more you can learn方式狀語中要注意的是as (連詞)與 like (介詞)的區別。 as 作為連詞其后接從句，如： please do it as i did it 但后面的句子 常作省略，如： please do it as i 而 like 是介詞，其后要接的是賓語，如： please do it like me
結果和目的狀語從句主要有 so … that， so that， in order that等幾種用法。
① so … that用在單數可數名詞前，so ＋ 形容詞 ＋ a ＋ 名詞 ＋ that，如： she is so beautiful a girl that everyone likes her 或用 such ＋ a ＋ 形容詞 ＋ 名詞 ＋ that, 如： she is such a beautiful girl that everyone likes her
② 在不可數名詞或可數名詞復數前只能用 such， 如： it is such good weather we want to go for a picnic 又如： they are such good players that they should win the game.
③ 在much， many， few， little 之前只能用so， 如： i have so little money that i can't buy it
④ so … that 之間只有形容詞時，則不能用 such， 如： it is so good that i want to buy
⑤ so that 其后接從句，如： i got up earlier so that i could catch the first bus
（二） 正誤辨析
［誤］ the stories in that book was written many years ago
［正］ the stories in that book were written many years ago.
［析］ 作主語的名詞、代詞或不定式、動名詞，它們往往要帶有修飾詞，這些詞可能是形容詞，也可能是短語，但謂語動詞還是要取決于這個主語的數，要記住的是一個名詞不可能在同一句中作兩個不同的語法成份，如： book 作了 of 的介詞賓語則不可能再作主語了。
［誤］ to read many books are good for you
［正］ to read many books is good for you
［析］ 不定式作主語應該看作單數主語。
