A.twohundredsof

B.twohundred

C.twohundreds

D.twohundredof［解析］句意：志愿者们在儿童节给一所贫困的乡村学校送了两百本书。two

hundreds

of错误表达；two

hundred“两百”；two

hundreds错误表达；two

hundred

of“……中的两百个”。根据“...

books

to

a

poor

village

school”可知，句中指志愿者们给学校送了“两百”本书。“hundred”前有具体数字时，不用复数形式，也不与“of”连用，直接用“数字+hundred+名词复数”。［答案］B考点二

had

one

cup”可知，现在喝的是“第二杯”，用序数词second。［答案］D考点三

A.twothirds；are

B.twothird；is

C.twothirds；was

D.twothirds；were［解析］句意：由于上周的特殊情况，我们学校约三分之二的学生在家通过互联网上课。空一处表示分数，分子用基数词，分母用序数词，当分子大于1时，分母需用复数，因此此处三分之二应表示为two

thirds；“分数+of+名词”作主语时，谓语动词常与of后的名词保持数的一致，of后the

students是可数名词复数，则谓语动词用复数形式，且根据“last

week”可知，时态用一般过去时，因此be用were。［答案］D1.(2025·达州)—Whenareyougoingonholiday？—I’mnotsure，perhapsthe
