终于懂了。把我的思路写出来:
题目要判断哪种情况:should occur but is unlikely to do so
1)should or shouldn't:
从以下这句判断:Reassessments再课税 should be frequent in order to remove distortions that arise when property values change at differential方向不同的 rates.
should------differential rate
2)likely or unlikely:
从以下这句判断:In practice, however, reassessments typically occur when they benefit the government – that is, when their effect is to increase total tax revenue.
unlikely------decrease |
