请英语语法专家回答 1.It is well konwn ______a person eats causes changes in the body A.that what B.that C.what D.how 2You will easily know______video recorders are the same A.what those B.that of those C.that all of Dwhich of those 3.we give him _________help we could a.what .b.that c.which d.this 怎么没人对啊
A 首先it is...that是强调句 然后what a person eats作为causes的主语 what是eat的宾语 B of those是video recorders的主人 因为后面说了是the same所以选that B 这里的help是名字,后面的we could作它的定语 用that
1C 2C 3A 1,C. what 引导主语从句,在从句中做eat的宾语. it 是形式主语,代替由 what 引导的主语从句. 其他选项:(从句中缺宾语,而that引导主语从句是不能充当任何成分的,故不选A. B.多了that,由 what引导从句就够了.C在从句中要做状语,意思也不对.) 2.C 宾语从句中不缺成分和意义,用that...
1. c it is well known 。。。it是形式主语 what a person eats 。。是真正的主语。 就是what a person eats。。。is well known 2。d kown后面+宾语从句。在那些video recorders中,哪些是一样的。 3。a what help we could(offer/give)
