    问答题
    Practice 6　　Movie-goers(电影院常客) across China will now only pay half price for tickets Tuesday, which will start in July. Any movie shown on Tuesday will be half price, even for new movies. The purpose is to bring people back to the cinema on Tuesday, when numbers of audiences are the lowest of the week. Some cinemas in Beijing and Shenzhen that began offering such discounts in advance have seen an increase in audiences Tuesday evenings.

    正确答案：
    【参考译文】
    从7月份开始,全中国的电影院常客们每周二花半价就可以去电影院看电影。凡周二上映的影片,甚至包括新片都是半价。周二是一周中观众最少的一天,在这一天实行半价政策,是为了把他们吸引回电影院来。周二半价政策已经在北京和深圳的一些影院提前开始实施,这些影院周二晚场的观众数量都有所增加。
    解析：
    　　①which引导的非限制性定语从句，代指前面句子描述的事情。
    　　②shown是被动语态作后置定语，修饰movie，可以译为“在周二上映的电影”。
    　　③when引导的时间状语从句，意为“在……时候”。
    　　④have seen/ witnessed为常用表达方式，主语是物而不是人，翻译时要转换为符合汉语表达习惯的句子。
