5.Languagepoints:

I’mreallyafraidofgoingtothedentist.

beafraidof害怕……，后跟名詞、代詞或動名詞，表示害怕會發(fā)生某事或某情況，相當(dāng)于bescaredof.

(1)beafraidtodosth.表示“因害怕而不敢做某事”

Heisafraidtogooutaloneatnight.

他不敢晚上一個人出去。

(2)“I’mafraid+從句”表示“我恐怕……”，常用來表達(dá)不愿發(fā)生的事情。

I’mafraidIcan’tgotherewithyou.我恐怕不能和你一起去那兒。

Idon’tknowwhy,butIhavehadthisfearsinceIwasveryyoung.

since為連詞，意為“自從……以來”，與現(xiàn)在完成時連用，其后可跟句子，也可跟“時間段+ago”。

Ihaveworkedheresincetwoyearsago.

我在這兒工作兩年了。

Ihadnochoicebuttogowithher.

havenochoicebuttodosth.意為“除了做某事以外，別無選擇”或“只好做某事”。

Ihavenochoicebuttogiveup.

我沒有辦法，只好放棄。

Fortunately,thedentist,Dr.Hu,wasverykind.

fortunately為副詞，意為“幸運(yùn)地”，其同義詞為luckily，反義詞為unfortunately/unluckily，其形容詞形式是fortunate。fortunately多用作插入語，比luckily更具強(qiáng)調(diào)性。

ShesawrightawaythatIwasscaredandtoldmenottoworry.

rightaway意為“立刻，馬上”，其同義短語有：atonce,inaminute/moment。

scared為形容詞，意為“對……感到恐懼的，害怕……的”。主語通常是人，指人對某事恐懼/害怕。bescaredof…意為“對……感到害怕”。

BeforeIknewit,myachingtoothwasfixed.

aching為形容詞，意為“疼痛的”，它是由ache去-e加后綴-ing構(gòu)成的形容詞。

(2)ache指人體內(nèi)部或外部的某一器官感覺上較持久的疼痛。常與head/tooth/stomach/back等表示身體部位的詞連用，構(gòu)成合成詞。

wasfixed是被動語態(tài)形式。當(dāng)謂語動詞與主語之間是動賓關(guān)系時，句子就用被動語態(tài)。被動語態(tài)中謂語動詞為“be+過去分詞”。fix的過去分詞在詞尾直接加上-ed。

Mytoothdidnothurtatall.

not…atall意為“一點兒也不，根本不”。

Idon’tknowaboutitatall.

對那件事我一點兒也不知道。

Itcanbeusedtoaddressdoctorssuchasdentists,surgeons,physiciansandsomeprofessors.
