【指点迷津】
单元重点词汇点拨
1 . have to 不得不，必须
〖 点拨 〗该词相当于must 。must含主观性比较强烈。have to含客观性强。
She doesn't feel well , she has to go to see a doctor . 她感到身体不好，她得去看医生 ( 看病 ) 。
注意对比：I must go home now . I have nothing else to do .
I have to go home now . I have an important thing to do . I will leave for Shanghai tomorrow .
2 . tidy 弄整洁，弄整齐
〖 点拨 〗该词可作动词也可作形容词。
Little Lucy can tidy ( up ) her own room . 小露茜能收拾她自己的房间了。
This is a tidy room . 这是整洁的屋子。
You must keep the room tidy . 你必须保持房间的整洁。
3 . washing 冲洗，洗 ( 衣 ) ，洗澡
I want to do some washing this evening . 今天晚上我想洗衣服。
〖 点拨 〗do some washing洗衣服。a washing machine洗衣机。
Please wait a moment . He is washing now .
4 . baby 婴儿，年龄最小的人
What a lovely baby ! 多可爱的婴儿啊 !
〖 点拨 〗a baby boy男婴，a baby girl女婴。
The baby is crying all the night . Perhaps she is ill .
5 . garden 花园，庭园，菜园
There are many kinds of flowers in the garden . 花园里有许多种花。
They are working in the garden .
6 . volleyball 排球
He likes playing volleyball very much . 他非常喜欢打排球。
〖 点拨 〗play volleyball打排球。注意球类名词前不用冠词。又如：
All the boys and girls are playing volleyball at the back of our school .
7 . instead 代替，顶替
Please give me this instead . 换这个给我吧。
〖 点拨 〗instead 是副词，常放在句末。
instead of 是介词词组，of 后面接名词、代词或相当名词的词。表示1 ) 代替，以代。如：
I will go instead of you . 我愿代你去。
2 ) 而不，而不是
Instead of working , he had a good rest . 他好好休息了一下而没有工作。
注意instead of连接的对等平行结构：They will go there by bus instead of on foot .
8 . mommy = mummy 妈妈 ( 美国英语 )
I am hungry , mommy . 我饿了，妈妈。
〖 点拨 〗口语中还用mum一词表示“妈妈”。mother是书面语。
9 . tired 疲劳的，累的
〖 点拨 〗注意 tiring 是“令人疲劳的”。That is a tiring job .那是一件令人疲劳的工作。
Are you tired ? 你累吗 ?
She looks tired out . 她显得疲惫不堪。
10 . rest 休息
Sit down and rest for a while . 坐下来休息一会儿。
Let's rest ( have a rest ) here , shall we ? 我们在这里休息一下，好吗 ?
〖 点拨 〗take / have a rest = take / have a break休息一下。
另外，rest还可以作“其余的”讲。The rest of the boys are short .
11 . problem 问题，习题
Today we'll think about the second problem . 今天我们要思考一下第二道习题。
〖 点拨 〗该词有待解决的问题，而 question 为有待回答的问题。
－ May I ask a question , Miss Gao ?
－ Of course , please .
12 . fat 肥的，胖的，
She is a fat girl . 她是个胖女孩。
Nobody likes fat now . 现在没有人喜欢吃肥肉。
〖 点拨 〗该词可作名词表肥肉。fat的反义词是：thin 。
My mother is thin , but my father is too fat .
13 . thin 瘦的，薄的，稀薄的
The ice on the lake is too thin for skating . 湖上的冰太薄，不能溜冰。
