Key phrases:

·be afraid of…

·need to do…

·have no choice but to do…

·dress in

·on the way to…

Key sentences:

·I don’t know why,but I have had this fear since I was very young.

·I had no choice but to go with her.

·My tooth did not hurt at all.

·It can be used to address doctors such as dentists,surgeons,physicians and some professors.

1.I’m really afraid of going to the dentist.

be afraid of害怕……,后跟名词、代词或动名词,表示害怕会发生某事或某情况,相当于be scared of。

I’m afraid of going out at night.

我害怕晚上外出。

【拓展】

(1)be afraid to do sth.表示“因害怕而不敢做某事”。

He is afraid to go out alone at night.

他不敢晚上一个人出去。

(2)“I’m afraid+从句”表示“我恐怕……”,常用来表达不愿发生的事情。

I’m afraid I can’t go there with you.

我恐怕不能和你一起去那儿。

2.I don’t know why,but I have had this fear since I was very young.

since为连词,意为“自从……以来”,与现在完成时连用,其后可跟句子,也可跟“时间段+ago”。

I have worked here since two years ago.

我在这儿工作两年了。

3.I had no choice but to go with her.

have no choice but to do sth.意为“除了做某事以外,别无选择”或“只好做某事”。

I have no choice but to give up.

我没有办法,只好放弃。

4.Fortunately,the dentist,Dr. Hu,was very kind.

fortunately为副词,意为“幸运地”,其同义词为luckily,反义词为unfortunately/unluckily;其形容词形式是fortunate。fortunately多用作插入语,比luckily更具强调性。

5.She saw right away that I was scared and told me not to worry.

◆right away意为“立刻,马上”,其同义短语有:at once,in a minute/moment。

◆scared为形容词,意为“对……感到恐惧的,害怕……的”。主语通常是人,指人对某事恐惧/害怕。be scared of…意为“对……感到害怕”。

6.Before I knew it,my aching tooth was fixed.

◆aching为形容词,意为“疼痛的”,它是由ache去-e加后缀-ing构成的形容词。

【辨析】

pain,ache

(1)pain既可指一般疼痛,又可指剧痛。疼痛范围可以是全身或局部,时间可长可短。

(2)ache指人体内部或外部的某一器官感觉上较持久的疼痛。常与head/tooth/stomach/back等表示身体部位的词连用,构成合成词。

◆was fixed是被动语态形式。当谓语动词与主语之间是动宾关系时,句子就用被动语态。被动语态中谓语动词为“be+过去分词”。fix的过去分词在词尾直接加上-ed。

7.My tooth did not hurt at all.

not…at all意为“一点儿也不,根本不”。

I don’t know about it at all.

对那件事我一点儿也不知道。

8.It can be used to address doctors such as dentists,surgeons,physicians and some professors.

be used to do sth.意为“被用来做某事”,属于被动语态结构。

Wood can be used to make paper.

木头可被用来造纸。
