考點三 表語
系動詞be作謂語時，與之搭配的部分被稱作表語，表語多由形容詞、名詞擔(dān)當(dāng)，也可是介賓短語、不定式、分詞或動名詞等
如：He is a doctor.
It’s fantastic.
She was in hospital.
以上句子中a doctor, fantastic, in hospital就是表語
例題：
(1)
Quasars----emitting extremely intense radio waves and visible radiation.
(A) starlike objects are
(B) starlike, they are objects
(C) are starlike objects
(D) are they starlike objects
答案：C
解釋：此句缺少謂語，C由系表結(jié)構(gòu)組成，原句中的分詞短語恰好作表語的定語。A B 與原句主語沖突，也不符合同位語的要求；D中they和starlike objects重復(fù)
(2)
Wherever there is plenty of rain during the growing season, life is ----in various forms.
(A) abundant
(B) the abundance
(C) an abundant
(D) it abundant
答案：A
解釋：空格處需要is的表語，B不可數(shù)名詞abundance之前不應(yīng)加the；C少名詞；D多代詞it; A形容詞，恰好作表語
