1.问 这一课我们学了nobody这个单词,但是我还不
答 知道everybody, somebody和anybody,它们有什么区别呢?
它们都是不定代词,下面是它们的用法,相信对大家会有所帮助。
(1) nobody意为“没人”,是否定词,表示否定意义,一般在句中作主语。例如:
Nobody is in the room. 房间里没有人。
(2) everybody意为“每个人”,表示集体概念,但当其在句中作主语时,谓语动词用单数形式。例如:
Everybody loves their parents. 每个人都爱自己的父母。
(3) somebody意为“某人”,一般用在肯定句中,但如果是表示请求等,可用在疑问句中。例如:
There is somebody outside waiting for you. 外面有个人在等你。
Can somebody help me? 有人能帮帮我吗?
(4) anybody意为“任何人”,一般用在否定句和疑问句中。例如:
I dont know anybody. (=I know nobody.)我一个人都不认识。
Does anybody want to go? 有人想去吗?
2.问 tall和high都有“高”的意思,它们之间有什么区别?
答 tall和high这两个形容词都表示“高”,但有时含义不同,可修饰的对象也不同。
(1) tall指从某物(或人)的顶端到底部的长度,与此物(或人)的宽度相对,往往含有高度远过于宽度,或高于同类物体的意味。它通常指人、树、建筑物等的高度,其反义词是short。例如:
Yao Ming is a very tall man. 姚明是一个身材高大的人。
There is a tall tree behind our classroom. 我们教室后面有一棵高树。
(2) high指高度,强调的是从地面或某基准面向上到某点的距离,通常用来形容山脉、高楼等,其反义词是low。例如:
That is a high mountain. 那是一座高山。
The table is one meter high. 这张桌子一米高。
(3) 注意tall和high的名词形式都是height(高度)。例如:
What is the height of the new station? 新车站有多高?
(4) high常用于比喻,表示程度、地位、时间、声音、价格等方面的“高”,而tall却不能这样用。例如:
Date_________ Weather_________
high temperature(高温),high price(高价),high speed(高速),high voice(高声),high summer(盛夏)等。
3.问 我们课文中有这样两个句子:1. Shes good-looking but shes a little bit quiet. 2. Shes short and a little bit heavy.请老师解释一下a little bit的用法,好吗?
答 好的。a little bit与a little同义,两者都意为“一点儿、少许”。She is a little bit quiet.也可说成Shes a little quiet.由于a little bit是固定结构,因此不可以将little和bit调换位置,也就是说,只能说a little bit,不可以说a bit little,这一点在使用时要特别注意。
4.问 What ... look like?是本单元里的一个主要问句,请问老师,怎么回答这种疑问句?
答 在What ... look like?中,如果主语是“人”,如What does she look like?/ What do you look like? /What do they look like? 则通常问的是人的“外貌”,因此答语通常是表示“相貌特征”的形容词或名词,如:Shes short./Im thin. /Theyre of medium height.等。如果主语是“某物”或“某个地方”,如:What does the hat look like?/What does the city look like?等,则通常问的是某物或某地的“外部特征”,因此答语通常是表示“外部特征”的形容词或名词,如It looks like a cat./Its very clean./Its a beautiful place. 等。
5.问 请给我解释一下She never stops talking.这句话,好吗?
答 好的。此句相当于 “She is always talking!”意为“她总是讲个不停!”。句中的never是副词,意为“从不;决不”,它在句中的位置与always在句中的位置相同。
stop在此是动词,意为“停止;终于”,常构成stop doing sth.与stop to do sth.两种结构。stop doing sth.意为“停止做某事”,强调停止现在正在做的事情;stop to do sth.意为“停下来去做另一件事”,强调停止现在正在做的事情,然后去做另外一件事情。例如:
Stop singing, please!请停止唱歌!
Stop to listen to me. 停下来听我讲。
6.问 本单元主要学习询问外貌与描述外貌,请老师给我归纳一下其常用句型,好吗?
答 好的。请看下面的归纳。
询问外貌的常用句型
1. What + do/does +某人(主语) + look like?, 侧重于询问人的长相或总体特征。例如:
—What does his brother look like? 他哥哥长得什么样子?
—He has a medium build. 中等身材。
2. What is/are+某人(主语) like?, 侧重于询问人的性格、气质、个性等内在的东西。例如:
—What is Miss Green like? 格琳小姐是个什么样的人?
—She is quite nice. 她相当和善。
描述外貌的常用句型
1. 从身高、体重方面:
My uncle is medium height. 我叔叔中等个儿。
Our English teacher is medium build. 我们的英语老师中等身材。
2. 从发型、面部特征方面:
Jack has curly hair. 杰克有一头卷发。
My P.E. teacher has a beard. 我们的体育老师留着胡须。
3. 从着装方面:
Date_______ Weather_________
They are wearing uniforms. 他们穿着制服。
【拓展】 有些描述人的短语不只有表面理解的含义,更多时候用其引申含义,所以使用时应该注意:
long face 可以指人的脸很长,更多时候表示不高兴,拉长脸。例如:
She has a long face all day long. 她整天拉长着脸。
big mouth 可以指人的嘴很大,也可形容人爱乱讲话。例如:
I dont like her, because she always has a big mouth. 我不喜欢她,因为她整天讲话。
big nose 可以指人的鼻子很大,也形容人总爱打听别人的私事。例如:
You have a big nose, Jim. This is private. 你真爱打听,吉姆,这是隐私。
