答案與題解：
1．C 第一段最后兩句說到，WHO估計每年有2000萬出生嬰兒體重過低，其中十個中有九個生于發(fā)展中國家，可見發(fā)達(dá)國家只占十分之一，故應(yīng)是200萬。
2．D 文章第二段第二、三句已經(jīng)說明，選項A、B、C均是多種維生素片所含的物質(zhì)，只有D項沒有提及，而且也不可能。
3．A 關(guān)于多種維生素制劑的作用，B項在第四段第二句提到，C項在第三段倒數(shù)第三句提到， D項在第三段最后兩句提到，只有A項在第四段倒數(shù)第二句中提到它時卻說維生素對它不起什么作用。
4．B 第三段最后一句是文章中一句說明淋巴細(xì)胞在身體中的作用的句子，故是正確答案，其他A、C、D三項都與淋巴細(xì)胞無關(guān)。
5．A 第四段第一句和第二句已經(jīng)將本題答案說得很清楚，其中的just under eight percent (只不足8％)正是A項的less than 8％。
