  解析:选C 句意:老年人读报纸不仅是为了娱乐也是活跃他们心理的一个很好的方法。此句中not only置于句首,第一个分句要用部分倒装。

  6.It is very ________ of you to notice that detail straight away.

  A.sharp B.enthusiastic

  C.eager D.aware

  解析:选A 句意:你真机灵,一下子就注意到那个细节。sharp"灵敏的,敏锐的,机警的,锋利的,尖刻的,尖的"; enthusiastic"热心的,热情的"; eager"渴望的,热切的"; aware"知道的,明白的,意识到的"。根据"一下子就注意到那个细节"可判断,你很"机灵"(sharp)。

  7.________ to smoking for a considerably long time, he has much difficulty quitting it.

  A.Having been addicted B.Being addicted

  C.To have been addicted D.Having addicted

  解析:选A be addicted to意为"对......上瘾"。分析句子结构可知,逗号前后的两个句子之间没有连词,故空格处应用非谓语动词。根据"for a considerably long time"可知,空格处动作发生在"has"之前,应用现在完成时;且"he"与"have been addicted to"之间是主动关系,故用其现在分词形式。故选A。

  8.________ strong and powerful China will certainly benefit ________ whole world.

  A.A; a B.The; a

  C.The; the D.A; the

  解析:选D China为国名,其前一般不加冠词,如果China被形容词修饰时,其前应该用不定冠词a;第二空特指"整个世界",应加定冠词the。故选D。

  9.The boss took no notice of the suggestion given by the clerk that the new technology ________ the problems on conveying the products.

  A.be applied to solve B.be applied to solving

  C.applies to solving D.applies to solve

  解析:选B 句意:老板不理会那个职员给的建议即新技术应该被运用到解决运送产品的相关问题上。分析句子结构可知,that引导suggestion的同位语从句,应用"(should+)动词原形"表示虚拟语气且此处应用被动语态,B项省略了should; be applied to doing"被应用于做......",符合句意。
