4. write the structure
【典型例題精析】
1. use the “it is +adj +that “structure to say how we feel about something.
（it is +形容詞 + that 從句）
在該句型結構中,it通常被稱作形式主語，而that從句才是真正的主語.that從句通常都被放在句子的末尾。能用于該句型中的形容詞有: clear, possible, wrong, sad, necessary, important, certain, true, surprising等。
eg.(1). it is clear that he is a cheat. 很顯然，他是個騙子。
(2).孩子們有足夠的睡眠是很重要的
complete the exercise in part a on their own. check their answers.
2. the structure “it is +to-infinitive” structure is similar to the structure students learned in part a except that here, the adjective describes an action or activity.
（ it is + 形容詞+ 動詞不定式）
在該句型結構中，it為形式主語，真正的主語為其后的動詞不定式。
