网友回答
(答案→)第一句中的第一个and→or
解析：
【小题1】第一句中的第一个and→or 根据句意可知这里的colleges和universities是并列的选择关系, 故用or。
【小题2】第一句中的in→on on one’s own为固定短语, 意为“独自”。
【小题3】第二句中的Go→Going 分析句子结构可知go to college为句子的主语, 故改为动名词形式。
【小题4】第二句中的peoples→people people本身为集体名词, 不需要加s变为复数。
【小题5】第三句中的municating→municate learn to do sth. 结构中to后接动词原形, 另外and前后连接并列的动词形式。
【小题6】第四句中的had→have 在固定句式“It is the first/second. . . time that. .. ”结构中, that从句中要用现在完成时。
【小题7】第四句中的away后加from be away from表示“远离……”。
【小题8】第五句中的by→with 表示“面对”之意, 要用be faced with。
【小题9】第五句中的our→their 根据主语是they可知本句的人称应该为“their”。
【小题10】去掉第六句中的with help为及物动词, 用作help sb. (to)do sth. , 故with为多余的。
