as…as 结构和反身代词
一、形容词原级的用法
1、说明人或事物自身的性质、特征或状态时用形容词原级
2、有表示程度的副词very, so, too, enough, quite等修饰时用形容词原级。
3、原级比较即同级比较，表示两者在某一方面相同时或不同时用原级。具体结构如下：
用法 例句
A+系动词/动词+as+原级+as+B,（肯定） 意为“A与B一样……”表示相同或相等（即A=B）. China is almost as big as the US, but it is the biggest country in Asia.
A+be/动词+not+so/as+原级+as+B （否定） 意为“A不及B那样……”表示不如或不相等（即A≠B）. I can’t run as fast as my brother.
A+be+倍数+as+形容词原级+as+B 意为“A是B的……倍”（常见倍数：一半half，一倍once，两倍twice，三倍及以上：数字+times）。 Our school is twice as large as theirs.
as much/many/……+as，表示前后的数量相同。 John earns an much money as his brother.
as+原级+as+用作比喻的名词 意为“像…一样”，此结构可形成许多习惯用于，多用于口语。 He is as busy as a bee.
二、反身代词
英语中共有八个反身代词，在使用时应注意和它所指的相应的对象在人称、性别、数上保持一致。其基本形式如下表所示：
人称 单数 复数
第一人称 myself ourselves
第二人称 yourself yourselves
第三人称 himself herself itself themselves
通称 oneself
用法详解：
反身代词有三种不同的用法：
一、强调用法
反身代词在强调用法中表示强调，即用来加强某个名词或者代词的语气，可译成“亲自”、“本人”。此时，它在句中作同位语。即使去掉，也不影响句子的完整性。例如：
（1）You must do it yourself.(你必须自己做)
（2）I myself did the homework last night。（昨晚是我自己做了家庭作业）
二、非强调用法
这种用法通常表示反身代词与句中的主语是同一人。它在句中作宾语，不能省略，否则该句是一个意义不完整的错句。例如：
（1）Jane is too young to look after herself.（简年纪太小，以至于不能照看自己）
（2）I teach myself English.（我自学英语）
（3）He didn't hurt himself, thank goodness.(他未伤了他自己，谢天谢地。)
三、与by搭配
当反身代词与by搭配时，意为：单独地，没有人帮助的。例如：
（1）We must finish it all by ourselves.（我们必须全靠自己去完成。）
（2）He can swim all by himself.（他能独自一个人游泳。）
一些常用的固定搭配:
teach oneself sth./ learn sth. by oneself 自学
enjoy oneself 玩得高兴；过得愉快
help oneself to sth. 请自用……（随便吃 / 喝些……）
say to oneself 自言自语
dress oneslef自己穿衣 lose oneself in沉迷于..

1．C
【详解】句意：——你的头发和玛丽的一样长吗？——不，不是。她的头发比我的长。

2．C
【详解】句意：——吉姆和亚历克斯起得一样早吗？——不，他起得比亚历克斯早。
考查形容词用法。early早的，形容词原级；earlier更早的，形容词比较级。as...as“像……一样”，中间用原级；根据“than”可知，第二空用比较级。故选C。
3．A
【详解】句意：现在乘高铁旅行和乘飞机旅行一样受欢迎。

考查原级的用法。根据“The shoes in Miller’s aren’t…the shoes on the Internet.”可知，此处表示“米勒店里的鞋不像网上的那么便宜”，空前有aren’t，故空处填形容词，故排除D项。A、B项为错误表达。not so/as+形容词原级+as“不如……”符合题意。故选C。
7．C
【详解】句意：它尝起来和看起来一样好吗？
考查形容词原级。well好，副词；best最好；good好的；better更好。taste是感官系动词，所以空处用形容词，as...as中间加形容词/副词原级，表示“和……一样……”，故选C。
8．C
【详解】句意：——安娜和莎莉一样高？——是的，但是她更外向。
考查形容词。tall高的；taller更高的；outgoing外向的；more outgoing更外向的。“as+形容词原级+as”意为“和……一样”，结合选项，第一空选tall；根据语境可知，答语意为“她更外向”，所以第二空是两者比较，应用比较级more outgoing。故选C。

考查形容词辨析及as+形容词原级+as。as good as和……一样好；as cheap as像……一样便宜；as low as和……一样低；as high as和……一样高。price“价格”，价格论高低。故排除选项A和B。根据“And some people plan to buy new energy cars”可知，汽油价格应该是不如去年低。故选C。
10．C
【详解】as句意：——爸爸，你能给我买一台电脑吗？——当然可以。这台电脑比那台更便宜，但是和那台一样好。
考查形容词的比较级和as…as的同级比较。此处第一空后的“than”可知强调这台电脑更便宜，故用“主语+be+形容词比较级+than”的句式结构，故第一空用cheaper；根据“as…as”可知此处是同级比较，故用“as+形容词原级+as”结构，as good as“和……一样好”。故选C。

12．A
【详解】句意：我认为吉姆不如他父亲有才华。
考查as…as的用法。根据“I don’t think Jim is as…as his father.”可知，not so/as+形容词原级+as表示“不如……”。故选A。
13．C
【详解】句意：李明，你的书写不像上学期那么好了。继续练习！

【2024秋季（牛津译林版）八上英语单元分块精准训练】
Unit 3 A day out (重点语法提升练)
as…as 结构和反身代词
一、形容词原级的用法
1、说明人或事物自身的性质、特征或状态时用形容词原级
2、有表示程度的副词very, so, too, enough, quite等修饰时用形容词原级。
3、原级比较即同级比较，表示两者在某一方面相同时或不同时用原级。具体结构如下：
用法 例句
A+系动词/动词+as+原级+as+B,（肯定） 意为“A与B一样……”表示相同或相等（即A=B）. China is almost as big as the US, but it is the biggest country in Asia.
A+be/动词+not+so/as+原级+as+B （否定） 意为“A不及B那样……”表示不如或不相等（即A≠B）. I can’t run as fast as my brother.
A+be+倍数+as+形容词原级+as+B 意为“A是B的……倍”（常见倍数：一半half，一倍once，两倍twice，三倍及以上：数字+times）。 Our school is twice as large as theirs.
as much/many/……+as，表示前后的数量相同。 John earns an much money as his brother.
as+原级+as+用作比喻的名词 意为“像…一样”，此结构可形成许多习惯用于，多用于口语。 He is as busy as a bee.
二、反身代词
英语中共有八个反身代词，在使用时应注意和它所指的相应的对象在人称、性别、数上保持一致。其基本形式如下表所示：
人称 单数 复数
第一人称 myself ourselves
第二人称 yourself yourselves
第三人称 himself herself itself themselves
通称 oneself
用法详解：
反身代词有三种不同的用法：
一、强调用法
反身代词在强调用法中表示强调，即用来加强某个名词或者代词的语气，可译成“亲自”、“本人”。此时，它在句中作同位语。即使去掉，也不影响句子的完整性。例如：
（1）You must do it yourself.(你必须自己做)
（2）I myself did the homework last night。（昨晚是我自己做了家庭作业）
二、非强调用法
这种用法通常表示反身代词与句中的主语是同一人。它在句中作宾语，不能省略，否则该句是一个意义不完整的错句。例如：
（1）Jane is too young to look after herself.（简年纪太小，以至于不能照看自己）
（2）I teach myself English.（我自学英语）
（3）He didn't hurt himself, thank goodness.(他未伤了他自己，谢天谢地。)
三、与by搭配
当反身代词与by搭配时，意为：单独地，没有人帮助的。例如：
（1）We must finish it all by ourselves.（我们必须全靠自己去完成。）
（2）He can swim all by himself.（他能独自一个人游泳。）
一些常用的固定搭配:
teach oneself sth./ learn sth. by oneself 自学
enjoy oneself 玩得高兴；过得愉快
help oneself to sth. 请自用……（随便吃 / 喝些……）
say to oneself 自言自语
dress oneslef自己穿衣 lose oneself in沉迷于..
