Question

19．野生動物的數(shù)量越來越少了．
The number of the wild animals is becoming smaller and smaller．．

Answer 1

分析 The number of the wild animals is becoming smaller and smaller．

解答 答案：The number of the wild animals is becoming smaller and smaller．這里是說正在進(jìn)行的事情，用現(xiàn)在完成時am/is/are+現(xiàn)在分詞，主語是野生動物的數(shù)量，用the number of表示"…的數(shù)量"，作主語時，謂語動詞用單數(shù)，故is，變得become，越來越少了，用比較級+and+比較級表示越來越…，數(shù)量少用small，故smaller and smaller，故答案是The number of the wild animals is becoming smaller and smaller．

點評 the number of表示"…的數(shù)量"，跟復(fù)數(shù)名詞連用作主語時，中心詞是number，謂語動詞要用單數(shù)．例如：
The number of students in our class is50．我們班學(xué)生的數(shù)量是50人．
a number of表示"許多"，相當(dāng)于 many，修飾可數(shù)名詞復(fù)數(shù)．作主語時，謂語動詞用復(fù)數(shù)．number前可用large，small等修飾，以表示程度．例如：A number of students are planting trees on the hill．許多學(xué)生在小山上植樹．
