Unit 5 Feeling Excited Topic 2 原因状语从句和形容词副词的原级 （时间：60分钟，满分：100分） 1. 原因状语从句 例句观摩: 1. She is crying in the bathroom because she did badly in the English exam. 2. She feels very lonely because she has no friends to talk with. 如上面的句子，because把两个句子连接起来的，because后面的那个句子在整个句子中充当状语成分，这样的句子叫作原因状语从句。（注：假如后面跟的不是一个句子，而是一个名词性短语则用because of 2. 形容词、副词的同级比较 (1) 表示两者在某方面程度相同时，用“as+形容词/副词原级+as+比较对象”句型。如：     I’m as tall as my father. 我和我父亲一样高。     He runs as fast as Jim. 他和吉姆跑得一样快。  (2) 表示某人或某物在某方面不如另一个人或另一物时，用“not as/so+形容词/副词原级+as比较对象”句 型。如：     Jane is not as/so brave as Maria. 简没有玛丽亚勇敢。      链接：“not as+形容词/副词原级+as”句型与“…+比较级+than…”可以互相转换。如：     This classroom is not as big as that one. 这个教室不如那个教室大。      =This classroom is smaller than that one.      =That classroom is bigger than this one. 1、 单项选择(本大题共50小题，每小题2分，共100分) 1． ________ it’s not a big deal, you can forget about it and be friends again.
