從語法結(jié)構(gòu)上來看,go是原型,前面一種可能是情態(tài)動(dòng)詞.
如：
we need/need should go to the same school
we will/shall/would go the same school
we can/could go to the same school
但英語里沒有B開頭的情態(tài)動(dòng)詞.
第二種可能是副詞,B開頭的副詞很多,只能推測(cè)：
we barely go to the same school.我們好不容易去了同一個(gè)學(xué)校
we basically go to the same school.我們基本上去了同一個(gè)學(xué)校
we blithely go to the same school.我們快樂地去了同一個(gè)學(xué)校
