[单项选择] It’’s hardly news that the immigration system is a mess. Foreign nationals have long been slipping across the border with fake papers, and visitors who arrive in the U.S. legitimately often overstay their legal welcome without being punished. But since Sept. 11, it’’s become clear that terrorists have been shrewdly factoring the weaknesses of our system into their plans.

Over a third of teachers in primary schools said they had experienced physical aggression, compared with 20% in secondary schools.
The government says teachers have sufficient means at their disposal to punish destructive pupils. However, almost 60% of those questioned for the Association of Teachers and Lecturers’ survey thought pupil behavior had worsened during the past five years. And the responses of the survey questioning over 1 000 teachers from primary and secondary schools appear to suggest that bad behavior is not the preserve of secondary schools.
One teacher at a primary school in England said: "A six-year-old completely trashed the staff room, put a knife through a computer screen, attacked staff and we had to call the police. A
