初三英语语法单词汇总
agobefore的用法区别
区别两者均表示“以前”,但ago以现在为基准,即指“现在以前”,因此常与一般过去时连用;而before以过去某一时间为基准,指“在那时以前”,因此常与过去完成时连用(且多用于宾语从句中)。如:
He left two years ago. 他是两年前离开的。
She said he had left two year before. 她说他是两年前离开的。
区别2  before也可泛指“以前”,不与具体时间连用。此时可用于现在完成时或一般过去时。如:
I have read the book before. 我以前读过这本书。
He didnt know that before. 他以前不知道此事。
有关age 的几条用法说明
说明1. 有关“年龄”(age)的常见表达:
How old is he? / Whats his age? 他多大年纪?
He is ten (years old). / He is ten years of age. 他10岁。
I have a son (of) your age. / I have a son the same age as you.
我有一个像你这样年纪的儿子。
Their ages are 47 and 9. 你们的年龄是4岁、7岁和9岁。
说明2. 表示“在……年龄时”,英语常用“at the age of +数字”(有时也省略为“at age+数字”,或改用 when 从句)。如:
He joined the army at the age of eighteen.
He joined the army at age eighteen.
He joined the army when he was eighteen (years old).
18岁时参了军
说明3. “他年纪 / 老”不能直择为:His age is young / old. 可译为:He is young / old
短语after all用法说明
1. 表示“尽管怎样,但还是……”,可译为“终究”、“毕竟”(通常放在句末)。如:
I was right after all. 毕竟是我对。
初三英语He tried for an hour and failed after all.
他试了一个钟头,终究还是失败了。
2. 表示“别忘了”(通常放在句首)。如:
I know he hasn’t finished the work but, after all, he’s very busy.
我知道他还没做完工作,但别忘了他很忙。
注:不要将 after all 理解为“最后”、“终于”,而与finally at last 混淆。
almost nearly的用法异同
一、相同之处
两者均可表示“几乎”“差不多”,均可修饰不定代词、形容词、副词、动词、介词短语等,此时两者常可换用。如:
Its almost [nearly] impossible. 那几乎是不可能的。(修饰形容词)
He almost [nearly] always arrives late. 他差不多总是迟到。(修饰副词)
He fell and almost [nearly] broke his leg. 他摔了一跤,险些摔断了腿。(修饰动词)
Almost [Nearly] all the students passed the exam. 差不多所有的学生都通过了考试。(修饰不定代词)
注意:修饰动词时,通常应放在行为动词之前,特殊动词之后(见上例);修饰形容词、副词、名词等时,通常应将其放在被修饰词语之前,否则会造成错误。如:
◎他工作了几乎一整天。
正:He worked almost all day.
误:He almost worked all day.
◎我们当中几乎每一个人都读过这本书。
正:Almost every one of us read the book.
误:Every one of us almost read the book.
二、不同之处
1. almost 可用于 any 以及 no, none, nobody, nothing, never 等否定词之前,但 nearly 一般不这样用。如:
Almost any man can do it. 几乎任何人都会做。
Almost no one came to the party. 几乎没有人来参加晚会。
I almost never see her. 我几乎从未见过她。
但是,两者都可用在否定动词之前。如:(www.zkenglish)
He almost [nearly] didnt catch the bus. 他差点没赶上公共汽车。
2. nearly 前可用 very, pretty, not 等词修饰,但 almost 之前不能用这些词。如:
Its not nearly so difficult as you think. 这远不像你想象的那么难。
The car is pretty nearly new. 这汽车几乎是全新的。
注:not nearly 意为“远非”,very [pretty] nearly 意为“几乎”,都是习语。
3. 有时 almost 可表示十分相似(但又不完全相同),此时不用 nearly。如:
I almost wish Id stayed at home. 我真有点后悔没在家里呆着。
Our cat understands everything — hes almost human. 我们这只猫什么都懂——快通人性了。
含有add的四个有用短语
1. add in 包括。如:

Would you add in these items, please? 请你把这些条款包括进去好吗?
2. add to 增加。如:
This adds to our difficulties. 这增加了我们的困难。
It adds to my pleasure to see you here today. 今天在这里见到你我格外高兴。
3. add up
(1) 加起来。如:
You havent added the figures up right. 这些数字你没有加对。
(2) 有意义,有道理(主要用于口语中,且主要用于否定句)。如:
His excuse just doesnt add up. 他的借口完全站不住脚。
What he said doesnt add up. 他说的话自相矛盾。
4. add up to
(1) 加起来等于,总计。如:
The figures add up to 500. 这些数字加起来等于500

(2) 总起来看说明了。如:(www.zkenglish)

angry的用法
1. 表示“对某人生气”,一般用介词with,有时也用at.
He got angry with (at) me. 他对我生气了。
注:有人认为用with表示心中感到生气,而用at则表示怒气流露于外表。但总的说来还是用with的场合较多。
2. 表示“对某事生气”,一般用介词about at。如:
She was very angry at what he said. 她对他说的话很生气。
I was angry about missing the film. 没看上那部电影我很所恼。
注:有人认为:at之后接某人之言行,about之后接某事,但种区别并不十分严格,两者常可混用。
