形容词的原级和比较级
语法展示
形容词和副词有三个比较等级，即：
1. 原级，也就是原形。
2. 比较级，表示“较……”或“更……”的意思。（用于两者之间比较）一般是在原级后面加er，等同于中文的“更…”。
3. 最高级，表示“最……”的意思。 （用于三者或三者以上的比较）一般是在原级后面加est，等同于中文的“最…”。
单音节词和部分双音节词 一般在词尾加-er smart-smarter
high-higher
以字母e结尾的词加-r fine-finer
wide-wider
重读闭音节词词尾只有一个辅音字母时，先双写该辅音字母，再加-er hot-hotter
big-bigger
以 “辅音字母+y” 结尾的双音节词，变“y” 为 “i”，再加-er early-earlier
happy-happier
多音节词和部分双音节词在其前面加more interesting-more interesting
popular-more popular
形容词的原级和比较级变化规则：
比较级要变化，一般词尾加 er。
词尾若有哑音e，直接加r就可以。
辅音字母若加y, 记得变y为i。
一辅重读闭音节，末尾字母要双写。
多、双音节有规律，词前加more就可以。

那是塔拉，对吗？此句是在That’s Tara. 这一陈述之后添加了一个附着的简略疑问结构，用以进行确认。(附加疑问句：前肯后否，前否后肯）
both adj. & pron. 两个；两个都
1) both用作形容词，置于被修饰的名词前。
Look at the three on both sides of the streets.
2) both用作代词，可单独使用，也可用于both of...结构。作主语时，谓语动词要用复数形式。
Both of my parents are Chinese.
My parents are both Chinese.
注意：both...and... ……和……都；既……又……
both...and...通常用来连接两个并列的句子成分，若连接两个并列成分作主语，谓语动词用复数形式。
eg: Both Ann and her brother like listening to soft music.
They both like listening to soft music.
反意疑问句:是指在陈述句后附加一个简短问句 ，用于征询肯定或否定的意见，或者希望陈述句所说的内容得到证实。简短问句的主语应为相应的代词（there be句型除外）。
常见形式：①肯定的陈述句+否定的简短问句
②否定的陈述句+肯定的简短问句
注意：答语应符合事实。事实是肯定的，用yes；事实是否定的，用no。当句式是“前否定，后肯定”的结构时，翻译要以事实为依据，yes译为“不是”；no 译为“是的”。
—There is someone in the room, isn't there 房间里有人， 不是吗
—Yes, there is. / No, there isn't. 是的，有人。/ 不。 没人。
A: That’s Tara, isn’t it
B: No, it isn’t. It’s Tina. Tina is taller than Tara. And she also sings more loudly than Tara.
