(1)It＋不及物动词(短语)＋that从句，that引导主语从句，常用于该句型的不及物动词(短语)有：seem(看上去)，turn ut(证明是)，appear(显得)，happen(碰巧)。(2)①s…that… 引导结果状语从句，意为“如此……以至于”。其常见形式为：
②such…that… 意为“如此……以至于……”，such后接名词。其常见形式为：
(3)“have＋宾语＋宾语补足语”的用法有以下几种： have sb. /sth. ding让某人做某事(动作具有持续、进行的含义) have sb. d让某人做某事 have sth. dne让/请别人做某事；遭受到

【句式剖析】 “the threat f chlera arund the wrld saw a substantial decrease”是一个以无生命的名词词组作主语的句式。“无生命的名词＋see/find/witness…”意为“……经历、发生、见证、目睹某事”。
有些动词，如see, find, witness等，可以用地点或时间名词作主语，表示某地或某时经历、发生、见证或目睹某事。

3．(P3)Mrever, in his use f maps and statistics, Snw transfrmed the way scientists study diseases. 【翻译】此外，通过使用地图和统计数据，斯诺改变了科学家研究疾病的方式。
【句式剖析】 “Snw transfrmed the way scientists study diseases”，是主从复合句。“scientists study diseases”是省略了关系代词that的定语从句，修饰“the way”。
在含有定语从句的复合句中，the way作先行词时有以下三种情况： (1)关系词在定语从句中作状语，关系词用in which，that或省略。(2)关系词在从句中作主语，关系词用that或which。(3)关系词在从句中作宾语，关系词用that, which或省略。
