a 8-year-old boy

an 8-year-old boy

a 8-years old boy

an 8-years old boy

考查形容詞和冠詞。句意：看！那邊有一個8歲的男孩。你認識他嗎？空格處為復(fù)合形容詞作定語，其基本構(gòu)成形式是：數(shù)詞+名詞（單數(shù)）+形容詞，并且要用連字符連接，排除C和D項；8發(fā)音以元音音素開頭，需用不定冠詞an修飾。故選B項。

          no bus,we had to walk home.

There was

There being

Because there being

It being

考查獨立主格結(jié)構(gòu)。句意：沒有車，我不得不走路回家。根據(jù)句意，表示“存在”，要用there be 句型；分析句子可知，設(shè)空處應(yīng)用非謂語動詞，there be只有主動形式，故用現(xiàn)在分詞；因為非謂語動詞有自己獨立的的主語no bus,所以此處是獨立主格結(jié)構(gòu)。故選B項。

The information tells me that the way of education in Canada is quite different from          in China.

one

it

that 

those

考察代詞。句意：這條信息告訴我們在加拿大的教育方式和在中國的教育方式很不一樣。前后比較的是教育方式，用that 指代the+名詞。A. one 是泛指一個，B.it 指的是同一個東西，D. those指代the +名詞復(fù)數(shù)。故選C項。

It has been warned that        to the surroundings with people infected by Covid-19 without any

protection can lead to severe result.

being exposed

exposed

having exposed

to expose

考查非謂語動詞。句意：有人警告稱，在沒有任何保護措施的情況下，暴露在有感染 Covid-19的人環(huán)境中會導(dǎo)致嚴重的結(jié)果。分析句子結(jié)構(gòu)可知expose在句中應(yīng)用非謂語動詞形式，表示“暴露”短語為be exposed to,且從句中缺少主語，expose 與主語people是被動關(guān)系，故應(yīng)用動名詞的被動式作主語。故選A項。
