20. Although the manager agreed to a more flexible work schedule, he said that it must be posted on the bullletin board so that both management and labor will know what everyone is assigned to do .
D.he said that the schedule would have to be posted on the bulletin board so that both management and labor would know what everyone was
答案:A
这题,我有三个问题:
1)LZM说,A比D好,是因为can 表主观,而have to 表客观,有宾语从句中,无需用had to 替代.这种区别在实际做题中,能用吗?好象不好把握啊.或者有什么其它判断标准.
2)管为东说:have to /be able to 的发起人一定是有生命的,可我在实际做题中,也发现发起人不一定是有生命体,这种规则在GMAT的实际考试中能用吗?
26,For some birds the sense of smell appears to play a role in navigation, since pigeones with surgicallly removed olfactory nerves were found to have increased difficulties in homing.
20（1）这个题目就可以用have to 用于“生命体和由人组成的组织”，后一种有拟人的思路。如果通过时态是无法判断，甚至D在其他方面比A要好，比如代词的使用....这时候就是抓住主要动词不放。“LZM说,A比D好,是因为can 表主观,而have to 表客观,有宾语从句中,无需用had to 替代”让LZM 得非典吧，这肯定是他杜撰的。
（2）注意拟人用法，这个很重要。拿题讲吧！
（3）时态是整个英语的难点，能闪就闪，学会回避难点。
26、比较选项如果非要从时态入手，是几乎不可能解这个题目的。
were found to have increased difficulties in homing
have been found to have increasing difficulty in homing.
