A. In spite of B. But for C. Because of D. As for 答案选B。 ‎ ‎(2)连词，如：so that, unless, in case, supposing, lest, provided(倘若……)，for fear that(唯恐)，in order that, on condition that, if only(要是……就好了)等。 ‎ She listened carefully in order that she might discover exactly what he wanted. =if she listened carefully, she might discover exactly what he wanted. ‎ If only I had more money, I could buy a car. ‎ ‎(注：lest, for fear that 和 in case 引起的从句中谓语动词多用should+动词原形，但可以不用虚拟语气，而用动词的陈述语气形式。)例如： ‎ The foreign teacher spoke slowly in case we misunderstood him. 这位外籍教师说得很慢以免我们听不懂。 Care must be taken in using this method lest overflow should occur.在使用此法时要小心谨慎，以免会发生溢流现象。 ‎ II: wish 后的 that 从句中:‎ ‎1. 表示现在或将来的愿望,从句中过去式.‎ ‎ I wish I knew his address.‎ ‎ I wish I were young.‎ ‎2. 表示过去没有实现或不可能实现的愿望, 从句用过去完成式或would, could, might + have + 过去分词.‎ ‎ I wish you had written to him.‎ ‎ I wish I could have slept longer this morning, but I had to get up and come to class.‎ ‎3. 如果将wish改成wished, 其后that 从句中的动词形式不变.‎ ‎4. 如果that 从句中用would , 一般表示 对现状不满或希望未来有所改变或请求 ‎ I wish he would answer my letter.‎ ‎ I wish prices would come down.‎ ‎ I wish you would help me.‎ ‎ I wish you would stop asking silly questions.‎ StepⅤ Exercises Ex.1----4 in using structures on page 43.Then check the answers.‎ Prepare for the Listening and Talking on page 41.‎ StepⅥ Homework Prepare for the Listening and Talking on page 41‎ Afterthoughts ‎ ‎ ‎ ‎ ‎ ‎
