1. 1.pile up (="lay" in a pile or as if in a pile) 把......放成一堆, 堆積：pile up the books on the table (把書堆在桌子上) 。Pile up作不及物動詞用, 意為“積壓; (若干汽車) 相撞”：1) Perishable goods are piling up at the docks. (碼頭上易腐爛的貨物堆積如山。) 2) Several cars piled up after ignoring the fog warning on the motorway. (由于無視高速公路上的大霧警告, 有好幾輛汽車相撞。)
2.be charged with受指控犯有......; He was charged with murder. (他受指控犯有兇殺罪。)
3.I am sure that +從句。He is sure to come. =" He" is certain to come.但在it作形式主語, that引導(dǎo)主語從句時, 主句中表語只能用certain, 不能用sure.
