Unit 18 Read the label! 看标签!
重点单词及拓展:
1. miss的用法
1) 未击中;未得到;错过
例:He threw the ball to me, but I missed it. 他把球扔给我,但我没接住。
I was late because I missed the bus. 我迟到了,因为我错过了公共汽车。
2)逃过;避开

4)怀念;思念
例:I'm sure that everybody will miss him very much. 我相信每个人都会怀念他。
注意:Miss表示未婚女性;年轻女教师
missing既是miss的现在分词形式,也是形容词,表示丢失的,迷路了。
例:My marker was missing. 我的笔找不到了。
do + 名词/动名词的用法,可以代替单独的动词
do my piano practice 练钢琴 do some reading 做一些阅读
do cleaning 打扫卫生 do washing 洗衣服
注意:这类短语要与go + 动名词短语区分开,如go shopping/swimming/fishing等也是固定用法,它们表示“去做......”。
造句练习1:
快点,否则(or)你会错过公交车。
--Tom,你怎么了?--我丢了我的英语书。
晚饭后,我会和妈妈一起做一些阅读。
once的用法
1)副词,一次;一遍;一倍
例:We go to the company once a day. 我们一天去公司一次。
He read this text only once yesterday. 这个课文他昨天只读了一遍。
2)副词,曾经;一度(常用于一般过去时)
例:Once he learned some English. 他曾经学过一点英语。
3)连词,一旦(连接时间或条件状语从句)

短语:once again 再一次 once a day/week/month...一天/周/月一次
at once 立刻;马上
拓展:twice 两次 three/four/five... times 三次/四次/五次.....
a bit的用法
1)a bit与a little都可作程度副词,表示“稍微、一点儿”的意思,修饰动词、形容词、比较级等,二者可以互换。
例:She's a bit/a little afraid of the teacher. 她有点怕老师。
This building is a little/a bit taller than that one. 这栋楼比那栋楼高一些。
a bit 不能直接修饰名词,要用a bit of + 不可数名词的结构,但a little后可接名词。
例:Tom has a bit of money in his pocket.=Tom has a little money in his pocket. Tom的口袋里有一点钱。
not a bit=not at all,意为“一点也不”
例:I don’t like that book a bit. 我一点也不喜欢那本书。
need的用法
实义动词,需要(和普通动词用法一样,有时态和人称的变化)
need + 名词/代词 需要某物/人
need sb. to do something 需要(某人)做某事
例:She needs to go there by bus. 她需要乘公交车去那。
2)情态动词,需要(和can的用法类似)后直接跟动词原型,need+do,否定 needn’t +do,没有人称和时态变化。
注意:need用作情态动词时常用于否定句和疑问句中。由need引出的一般疑问句,肯定回答常用must或have to;否定答语常用needn't.
对比例句:
My mum doesn’t need to go shopping tomorrow.
My mum needn’t go shopping tomorrow. 我妈妈明天不用去超市。

定义:和感觉器官有关的系动词,称为感官动词,常见的有look(看起来),sound(听起来), smell(闻起来),taste(尝起来), feel(摸起来;感觉)以及hear, watch,see, notice等。
感官动词look,sound, smell,taste, feel引导的主系表结构。
感官动词+形容词。

I always feel sick on buses. 我乘公交车时总会觉得恶心。
感官动词+ like + 名词 听/看/闻...起来像
例:That sounds like a good idea. 那听起来像个好主意。
注意:
1)这类动词虽然有系动词的功能,但它们有时态和人称的变化;变否定句和疑问句时,用法和普通的实义动词一样,要借助助动词。
Does the party sound noisy 聚会听起来很吵吗?
2)这类动词还可以用作普通的实义动词,要根据语境进行区分。
He looks very happy, so he looks at us happily. 他看起来挺高兴,所以他高兴地看着我们。
