Part 05Summary
Part 06Language pints
1. Typhns frm when warm water frm the cean meets certain wind patterns.
分析结构：这是一个含时间状语从句的复合句。主句结构：Typhns 主语+ frm 谓语，之后是时间状语从句。引导词when 表示“当……时”。从句结构：warm water 主语+frm the cean(介词短语作后置定语，修饰 water)+meets 谓语+ certain wind patterns 宾语。
when 引导的时间状语从句的用法：主句为一般现在时，从句也用一般现在时(表示客观规律)。若主句是一般将来时，从句常用一般现在时表将来(主将从现)。还可根据实际语境用过去相关时态。
e.g. Plants grw faster when they get enugh sunlight and water. 当植物获得足够阳光和水分时，生长更快。I will call yu when I arrive at the statin.我到达车站时会给你打电话。When she entered the rm, he was reading a bk.当她进入房间时，他正在看书。

4. During a typhn, wind speeds can reach up t 252 kilmetres per hur r even higher.
