______too much TV isn’t good _______our eyes.
A．Watch , to B．Watching ,for C．Watch ,for D．Watching ,to
B
                                                                               
試題分析：根據(jù)isn’t可知，前面的部分應(yīng)該是主語，動詞原形不能作主語，動名詞可以作主語，所以應(yīng)該排除AC；be good for“對…有益處”，而be good to“對…友好”，根據(jù)句意應(yīng)該用be good for。本句的意思是“看太多的電視對我們的眼睛沒好處�！彼员绢}選B。
點評：應(yīng)將動名詞作主語的情況和祈使句區(qū)分開來。動詞原形可以放在開頭，這是祈使句。另外，應(yīng)區(qū)分有關(guān)good的短語，如：be good at，be good to ，be good for，be good with 等。
