I want to learn how()quickly.a.run b.to run c.runs d.ran填什么请解释
还有一个问题：The sitting room needs(),but it'll have to wait until Saturday.a.cleaning b.to be cleaned .c.clean d.being cleaned填什么请解释

第一题：是run,选A.第二题选Acleaning.
怎么解释呢,其他的要么是错的要么不是最好的.第一个用to run 也没有错,但为什么不选他呢,因为他有两个单词,当然要选简单的那个了.第二个needs 是动词,动词后面要加个名次词.所以选cleaning最合适.B D选项显然多余了,因为有了need 就不需要被动语态了.
再问：可我练习册第一题选 TO RUN，第二题选TO BE CLEAN
再答：我说我的对，你相信不？我英语已过国家六级水平测试。
再问：不是不信，您别生气只是有疑问
再答：没有生气撒，第一题用 how to 给人的感觉就是你还不会跑步，教你怎么跑步，用how run 就是你已经会跑步了，只是需要一些技巧，提高速度。
