省略了关系代词that。
先行词为不定代词时,关系代词只能用that。
4)the+序数词+最高级+N 第几(大/长/高…)One of the/形容词性物主代词+Ns 谓语用三单例:He is now one of the best students in his classOne of my best friends is a doctor.One of his most expensive pens has been lost.The yellow river is the second largest river in china.Mount Qomolangma is the first highest mountain around the world课文重点内容补充讲解a. 词汇:be interested in对……感兴趣该短语后接动词-ing形式、名词或代词,其主语必须是人或其他有生命的东西。
它相当于show/take/have/feel (an) interest in,其中interest为名词,意为“兴趣”。
其中be可换用get或become以强调由不感兴趣到感兴趣。
【例句】She’s interested in collecting shells. =She sh ows an interest in collecting shells. 她对收集贝壳感兴趣。
He became very interested in science when he was ten. 他十岁时就对科学产生了兴趣。
(以前不感兴趣,十岁时开始)【横向】interesting & interest1.interesting作形容词,有主动意味,意为“令人有趣的”,作表语时,主语通常是物。
作定语时,既可修饰人,也可修饰物。
【例句】The story is very interesting. 这故事很有趣。
This is an interesting book. 这是本有趣的书。
2.interest作不可数名词时意为“兴趣、趣味”。
作动词时意为“使(人)发生兴趣”,其主语多为事物。
【例句】They're all places of great interestinChina. 它们都是中国的名胜。
Your story interestsme. 你的经历引起了我的兴趣。
【课堂变式】I have ___ to tell you. Maybe you will be _____ in it.A. interesting something; interestedB. something interesting; interestingC. something interesting; interestedD. something interested; interesting【解析】形容词修饰不定代词时,应该放在其后面,可先排除A。
另外,修饰某物时要用interesting,可排除D。
第二空的you是人,故要用be interested in结构。
答案选择C。
b. 句式:1.Mario, you used to be short, didn’t you?马里奥,你过去很矮,对吗?used to do sth 意为“过去常常做某事”,特指在过去经常发生的动作,而现在已不再发生,其中used to 可以看作情态动词,用于各种人称。
【例句】He used to play soccer when he was young. 他年轻时经常踢足球。
(现在不踢了)She used to be an English teacher. 她过去是一位英语老师。
(现在不是英语老师了)1.其否定句为didn’t use to do或used not to do,used not可缩写为usedn’t。
【例句】Mr Li didn’t use to drink beer.=Mr Li usedn’t to drink beer. 李先生不常喝啤酒。
ed to 的疑问句形式是“Did…use to do?”或“Used…to do”。
【例句】Did she use to get up early?=Used he to get up early? 她过去经常早起吗?ed to 的反意疑问句也用助动词did(n’t)或used(n’t)构成。
【例句】Mario used to be late for school, didn’t/usedn’t he?马里奥以前上学经常迟到,对不对?【横向】be used to do sth & be used to doing sth.1.be used to do sth表示“被用于做某事”,是被动结构,强调主语是动词use的承受者。
【例句】Wood can be used to make desks. 木材可用来制作书桌。
Stamps can be used to send letters. 邮票可用来寄信。
2.be used to doing sth意为“习惯于做某事”,其中to是介词,后须接名词或动词-ing形式。
【例句】I was used to the hard life here. 我习惯这里的艰苦生活。
He is used to working before six in the morning. 他已经习惯每天早晨六点以前干活。
