advice,suggestion,proposal,request,order,idea等，

從句謂語(yǔ)形式是“should＋動(dòng)詞原形”(should可以省略，但不可換成would)。Mysuggestionisthatwe(should)startearlytomorrow.我的建議是我們明天早點(diǎn)出發(fā)。[巧學(xué)活用2]——語(yǔ)法填空①IdrovetoZhuhaifortheairshowlastweek.Thisis________Ihadafewdaysoff.②Hewaslatetoday.Thisis________hegotuplate.③[2022·新課標(biāo)全國(guó)卷讀后續(xù)寫]Thereasonwhyyous
