39、Susan is reading a storybook now. 苏珊正在看一本故事书。2. 现在完成进行时和现在完成时比较：有些动词 (如：work, study, live, teach 等)用现在完成进行时与现在完成时表达的意思差不多。试比较：The teacher has been teaching at this school for ten years. 十年来，那位老师一直在这所学校教书。The teacher has taught at this school for ten years. 那位老师在这所学校已经教了十年书了。英语中的多数动词在这两种时态中表示不同的含义。现在
