adj 修 饰 事 物 / 动 作用 fr
adj 修 饰 描述人 ( 品格 / 性格 / 品德 ) 用 f
修 饰 事 物 / 动 作常用的adj：imprtant (重要的) /necessary (必要的) / difficult/ hard(困难的）/easy（容易的）/pssible（可能的）/ impssible（不可能的）/useful（有用的）dangerus（危险的）/interesting（有趣的）/ bring（无聊的）It is necessary fr us t keep quiet in the library.It was difficult fr him t finish the wrk alne.It is useful fr students t take ntes in class.
修 饰 人常用的adj：kind (善良的) /nice（友好的）/plite（礼貌的）/ rude（粗鲁的）/ clever/smart（聪明的）/flish/silly（愚蠢的）/brave（勇敢的）/careful（细心的）/ careless（粗心的）/selfish（自私的）/generus（慷慨的）It is kind f yu t help me with my English.It is brave f the little by t save the cat.It was careless f him t make s many mistakes.
“It is/was+形容词+that ...”的用法
“It is/was+形容词+that ...”意为“……是……的”。用来表达对某件事的评价、观点或感受等。在该句型中，it是形式主语，that从句是句子真正的主语。当主句用is时，从句根据实际情况用一般现在时、一般将来时等；当主句用was时，从句常用表示过去的某种时态。It’s wnderful that ur hmetwn has changed a lt. 我们的家乡变化很大，真是太好了。◆ It was strange that he didn’t cme t schl tday. 他今天没有来上学，真奇怪。
易错点解析：① that从句的引导词：that不可省略, 即使从句语义完整, 也必须保留that如不能说“It is clear he is lying”，需说“It is clear that he is lying”.② 虚拟语气的使用：仅当形容词是“表建议、要求”类（如 advisable, desirable）时，that从句才用虚拟语气；其他类形容词后的that从句用陈述语气，时态根据实际语境调整；
与“it + is/was + adj. + t d sth.”的区别：两者核心都是it作形式主语，区别在于真正主语——前者是that从句（表达完整的事实/观点），后者是不定式（表达具体的动作），不可混淆。真正主语是that从句，形容词多为表示观点、态度的词，如true, clear, bvius, certain, strange, surprising等。It is clear that he is lying. 很明显，他在撒谎。It is strange that she didn’t cme t the party.她没来参加派对，真是奇怪。
