Trap 10 插入隔离型(10)
9.不要受however的干扰 An awful accident, however, occur the other day. A. doesB. didC. has toD. had to 此题正确答案应选B，句末的the other day意为“前几天”，所以句子应用过去时态，而选项D填进去不合题意，故选B。此句有两个难点：一是句中插有however一词，分散了同学们的注意力；二是所填选项B为许多同学所不熟悉的强调用法。 (1) Your mother, however, say that to us that day. A. doesB. didC. is doingD. was doing (2) Our math teacher, however, speak English well. A. doingB. doesC. is doingD. was doing 以上两题答案均选B，其中的does, did均为强调用法。 相关新闻
