(教材P28)【句式分析】这是一个含有with复合结构的简单句。

句中的＂with black and white lines going beneath their stomachs＂作后置定语，修饰＂some zebra＂。

【重点语法】with的复合结构为＂with +宾语(n. /pron. )+宾语补足语＂。

在句中with复合结构多数充当状语, 表示行为方式、伴随情况、时间、原因或条件等。

with复合结构在句中也可以作定语。

with复合结构的具体形式：☛He often sleeps with the windows open. 他经常开着窗睡觉。

(教材P30) 【句式分析】该句为复合句，who 引导宾语从句；how 引导宾语从句，how 在从句中作方式状语；not …until…＂直到……才……＂引导时间状语从句。

【重点语法】not …until…的用法：(1)当not until 位于句首时，句子要倒装。

其结构为：Not until+从句/表时间的词+助动词+(主句)主语+谓语+…。

(2)not …until …句式的强调句型为It is/was not until …that …。

☛It was not until yesterday that I noticed it. 直到昨天我才注意到此事。

☛Not until the teacher came in did the students stop talking. 直到老师进来学生们才停止讲话。

【拓展延伸】until 与not . . . until. . .until ＂直到＂，表示某一种行为一直持续到某一时间。

用在肯定句中，句子的谓语动词必须是可延续性的；not …until … ＂直到……才＂，表示直到某一时间，某一行为才发生，之前该行为并没有发生。

用在否定句中，主句中的谓语可以是延续性动词，也可以是短暂性动词。
