答案与题解：
1. B 题句说2007年4月28日的地震致使全英格兰都停电，与短文第一段第一句表达的内容不符。短文说地震殃及英格兰东南部的肯特郡部分地区，电力中断，几千名居民无电可用。所以，题句是错误的，答案为B.
2. C 本题所说的意思是：地震发生后，海峡隧道关闭了10小时。题句表达的内容短文中找不到，故答案为C.
3. A 题句的意思是：地震中一个妇女的头部和颈部受了点轻伤。题句表达的意思与第一段最后一句表达的内容相符。所以选项A是答案。
4. C 题句表达的意思是：法国和其他几个欧洲国家派遣他们的医疗队去英国与当地的医生并肩工作。这一内容短文中找不到，故答案为C.
5. B 题句所说的英国最强烈的地震于1580年发生在伦敦，这与短文表述的事实不符。短文第七段第一句明白无误地说，英国最强烈的地震于1931年发生在北海。题句表达的信息是错误的，故答案为B.
6. A 题句说Masson预言在英格兰东南部迟早将发生另一次地震。这一说法与短文最后一段第三句所表达的意思相符。所以答案是A.
7. A 短文第六段第一句说，全球每年发生强度为里氏4级左右的地震有几千次，但是这种中等强度的地震在英格兰很少发生。据此，读者可以容易地推断出，高震级的地震在英格兰就更少见了。
