答案

C A B A A A
1.funiture是不可数名词,没有复数形式,因此排除B、D ,说有几件家具,通常是many pieces of furniture 或者many set of furniture
2、3题是一种类型的题,都是考察连字符号的,遇到这种题型,一般情况下,你只要选带有连字符好的且连字符号所缀连的单词都是单数形式这一项!它在句中充当定语,例如：一个两岁的男孩,可以说成“a two years old boy”,用连字符号就变成“a two-year-old boy”!
4.整个句子的意思是“电脑科技在20世纪90年代发展迅速”,computer science 是单数,所以谓语动词也相应的用单数形式,因此排除C、D,因为电脑科技发展迅速这个动作已完成的,并将可能持续发展下去,所以用现在完成时态!即是说应选择A
5.考查damage为不可数名词,没有单数形式,damage意为“损害”,整个句子意为：风暴对这个地区已经造成很大的损害.
6.hundred,million,billion只有与of连用时才用复数形式,且用基数词修饰!所以最后一题选择A
