sit in for 是一个词组么?原句是 millions of college students sit in for the post百度和词霸我搜了搜不到,给这个句子的翻译也成, sink in 是词组么? search for和in search of 有什么区别,我知道一个是动词词组,一个是介词词组,但是不知道怎么用在句子里 have in是一个词组吗? “sit down”是一个祈使句还是一个短语呢?还有补充说明一下短语与词组有什么区别? we have enough chair for everyone to__ A:sit B:sit on C:sit in D:sit atsit on 和sit in都有什么区别? 是sit in the sofa 还是sit on the sofa? 是sit on the chair还是sit in the chair 是sit in a chair还是sit on a chair? 请问这句句子中词组的含义原句：I have enough to live off of for about 3 months.翻译：我有足够的钱支持我生活3个月其中：live off 是 “依靠.生活”的意思其中的 “of”起到一个什么作用?与句子中哪 might 是一个词组么? wouldn't he be cold sitting right there?这句怎么翻译,be cold sit是词组,还是right there是词组怎么理解其中的成分,是词组,还是单个理解,我想仔细分析这句话,谢谢 sit on seat 这个词组 是sit on还是 on seat啊 帮忙分析下这句英语里词组the Union is calling for a national day of direct action and expects sit-ins and occupations to be staged in protest at the higher fees in large numbers of colleges.主要是这里的看不懂be staged in protest a bad,eyes,reading,for,sun,the,in,is,your.（连词组句） China,he,holiday,in,be,for,his,will.（连词组句） 求两句英语原句,只知道发音不知道究竟是哪些词组成的句子in did（发音）意思是：没错=w=well well（发音）意思是：瞧瞧谢谢!第一个意思是：没错/就是这样 一个术语,有关工科或者机器人里面有stubs/stub这个词是什么东西?原句来源“Stubs are supplied for all projects and you fill fill in the code”.Stubs是程序包?还是一种语言还是一种理论?
