Unit 2 The environment單元復(fù)習(xí)學(xué)案
(3)there be中be的單復(fù)數(shù)取決于be后的名詞,若有幾個(gè)并列名詞,則取決于第一個(gè)。
(4)there be+n.+v.ing/v.ed/to do中,若名詞與后面的動(dòng)詞存在主動(dòng)關(guān)系,用v.ing形式;若表被動(dòng)關(guān)系,則用v.ed;不定式既可以用主動(dòng)形式又可以用被動(dòng)形式。
17.(XX年高考安徽卷)________a certain doubt among the people as to the practical value of the project.
a.it has b.they have
c.it remains d.there remains
解析:選d。考查固定句型。此句實(shí)際是考查句型“there is a certain doubt”,這里用系動(dòng)詞remains代替了is。
