          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。
